 release time : 2022-01--23  Traffic : 0

Classification And Technical Characteristics Of Crimping Machines The crimping machine is the same as other machines, and its types and functions are also varied. The classification of crimping machines can be divided into hydraulic high-pressure pipe crimping machines, brake pipe crimping machines, air-conditioning pipe crimping machines, power hose crimping machines, etc. according to the function of use, such as straight barrel crimping machines and double-column crimping machines according to their mechanical structure Machine, open-type crimping machine, C-type crimping machine, such as the control method can be divided into electromechanical crimping machine, PLC-type crimping machine, CNC-type crimping machine. Withholding machine technical guidance: 1. The operation principle of double hydraulic circuit is adopted, that is, the advance and retreat of the piston and the opening and contraction of the mold are all powered by the hydraulic power source. It not only moves smoothly and returns quickly, but also does not cause the phenomenon of spring return, which makes the mold unable to open and locks up. Moreover, the design of the cylinder locking system is through the front and rear, which is easy to crimp various special-shaped elbows. 2. The hydraulic system consists of a motor, an oil pump, a solenoid valve, a pressure regulating valve and a hydraulic valve to form a dual hydraulic oil circuit with forward and backward motion, and a quick oil drain valve oil circuit is added to the dual hydraulic oil circuit to achieve more The purpose of quick return, and the speed is adjustable, the noise and system pressure are reduced. 3. In terms of electrical control system, the control circuit is suitable for PLC circuit, which is easy to repair the circuit, easy to maintain, and simple to replace. 4. The crimping die and die base are processed with no cumulative error to ensure that the crimping lines of the product after crimping are evenly spaced and there is no big or small head phenomenon. 5. For the permanent mechanical precision and life of the crimping machine, not only high-quality alloy steel materials are selected for the components of the locking mechanism, but also a unique heat treatment process is adopted. Therefore, the long service life of the crimping machine is inseparable from the rationality of material selection, heat treatment, mechanical processing technology and structure. 6. For the double-column crimping machine and the C-type crimping machine, the crimping size must be controlled by numerical control because it is inconvenient to set the dead position.

Talking About The Selection Of Hydraulic Oil For Crimping Machine

 release time : 2022-01--21  Traffic : 0

Talking About The Selection Of Hydraulic Oil For Crimping Machine 1. Appropriate viscosity, good viscosity-temperature characteristics Viscosity is the first factor to consider when selecting hydraulic oil. Under the same working pressure, if the viscosity is too high, the movement resistance of hydraulic components will increase, the pressure drop of the pipeline and the power loss will increase; if the viscosity is too low, it will increase the volume loss of the oil drum. The internal leakage of the component increases, and the oil film of the sliding parts is thinned, the supporting capacity is reduced, and there is atomization, which overflows from the exhaust port. 2. Good lubricity (anti-wear) The hydraulic system has a large number of moving parts that need to be lubricated to prevent the wear of the relative moving surfaces, especially the hydraulic equipment with high pressure, which requires much higher anti-wear properties of the hydraulic oil. 3. Good antioxidant properties Hydraulic oil will also be oxidized during use. The acidic substances produced by the oxidation of hydraulic oil will increase the corrosiveness to metals, and the resulting sludge deposits will block filters and small gaps, causing the equipment to work abnormally. Therefore, it is required to have good of antioxidant properties. 4. Good rust and corrosion resistance Hydraulic oil will inevitably come into contact with moisture and air during use, as well as acid substances generated after oxidation, which will affect the corrosion of the metal valve core, so that the hydraulic crimping machine equipment cannot work normally. It is recommended to completely replace the old and new oil in 3-5 years.

How To Crimp A Satisfactory Hose With A Crimping Machine And A Hose Crimping Machine

 release time : 2022-01--20  Traffic : 0

How To Crimp A Satisfactory Hose With A Crimping Machine And A Hose Crimping Machine The technicians of the BNTFLEX crimping machine manufacturer are here to explain how to use the crimping machine to crimp a satisfactory hose. The high-pressure oil hose is mainly divided into high-pressure steel wire braided oil hose and high-pressure steel wire wound oil hose. The high-pressure steel wire braided oil hose is mainly composed of black oil-resistant synthetic rubber inner rubber layer. , middle rubber layer, Ⅰ, Ⅱ, Ⅲ layers of steel wire braided layer, weather-resistant synthetic rubber outer rubber layer. The high-pressure steel wire winding oil hose is mainly composed of inner rubber layer, middle rubber layer, 2, 4 and 6 layers of steel wire winding layer and outer rubber layer. When the user crimps the high-pressure oil hose with the crimping machine and the hose crimping machine, if the crimping amount is too small, the pressure between the fittings and the hose is too loose, and the rubber hose of the crimping machine may be released from the fitting at the beginning of use under the action of oil pressure. , If the withholding amount is too large, then the joint and the hose are pressed too tightly, which will easily lead to local damage to the inner layer of the hose, resulting in cracks. out, or have been running along the steel wire layer to accumulate somewhere, causing the outer layer of rubber to bulge or even rupture. When crimping with a crimping machine and a hose pressing machine, the crimping speed should not be too fast, which will easily cause damage to the inner rubber and rupture of the steel wire layer, which will cause the hose to be damaged prematurely in use. In actual work, when replacing the high-pressure hose, the length of the hose, the number of steel wire layers, the shape and size of the joint should be reasonable, and the bending degree of the hose should be minimized. Most of the damage to the high-pressure hose is caused by improper production. . It is hoped that when users use the hose crimping machine to crimp the high-pressure oil hose assembly, they can correctly select the high-pressure oil hose and buckle out the satisfactory hose assembly.

Selection And Design Consideration Of Crimping Machine

 release time : 2022-01--20  Traffic : 0

Selection And Design Consideration Of Crimping Machine More than 95% of the power source of the crimping machine today uses the hydraulic system, and it is occasionally used in the crimping machine that only presses the low-pressure oil pipe or the crimping machine of the sanitary pipe that uses the pneumatic system or the lever to provide the power. The oil pump of the hydraulic system is equivalent to the heart of the human being, and its function is very important. The selection of the gear pump as the power source of the crimping machine often considers factors such as its low cost, cost saving, and low requirements for oil cleanliness, but its shortcomings For: the supply pressure is low, only equivalent to 60% of the pressure of the plunger pump, the noise is large, and the service life is short. Due to the low supply pressure, in order to increase the withholding pressure, manufacturers often consider sacrificing the shrinkage and expansion capacity of the withholding machine. Improve the transformation of the axial force and radial force of the crimping machine, so often when the customer's requirements are not high, the gear pump crimping machine can be selected. The plunger pump is used as the power source of the crimping machine. The advantages are: high pressure (300kg/cm2), long life of the pump, low noise, such as automatic variable oil supply for YCY series, low pressure large flow, high pressure small flow, the same specifications The motor saves 30% of electricity, and the hose withholding is not easy to leak oil. Because the system is high, the design can achieve a larger opening under the same withholding pressure, so that customers can use it for a long time. But its disadvantages are: higher cost, the same displacement pump, the plunger pump is 8-10 times that of the gear pump, which increases the cost of a single machine, and requires relatively high oil cleanliness, but consider the basic performance. Input-output ratio, it will be very cost-effective to choose YCY system variable pump crimping machine.

Experts Analyze The Reasons For The Failure Of The Pressure Pipeline System

 release time : 2022-01--18  Traffic : 0

Experts Analyze The Reasons For The Failure Of The Pressure Pipeline System The experts of the withholding machine manufacturer will analyze some faults in the pressure pipeline for us today, and analyze the reasons for the faults. The hydraulic pipeline system of construction machinery is the power transmission system of the main engine of construction machinery, which can be described as the blood of the whole machine. The quality problems existing in the hydraulic pipeline system of domestic construction machinery are mainly manifested in the oil leakage, oil seepage and cleanliness of the pipeline system, and the product quality is not up to standard. Causes of failure of hydraulic hose assembly: (1) When the hydraulic hose assembly is crimping the fittings the crimping pressure is too large, and the inner rubber layer of the hose is damaged, causing oil leakage. (2) When the hydraulic hose assembly is crimping the fittings, the crimping pressure is not enough, resulting in oil leakage, oil leakage and pulling off. (3) Under the action of repeated pulse pressure, the jacket rebounds and the buckle pressure decreases, resulting in oil leakage, oil leakage and pulling off. (4) The machining accuracy of the joint is not up to standard, resulting in oil leakage and oil leakage at the interface. (5) The use method is incorrect, resulting in reduced service life. During the operation of the hose crimping machine, the operator needs to be familiar with the relevant production processes, be proficient in operating the crimping machine, tools, and labor protection supplies, and can only take up work after they are fully dressed. Before starting the machine, ensure that all fasteners are firm, that each running part and moving surface are free of obstacles, and that safety protection devices are complete. The joint surface of the mold seat and the mold should be kept clean, and there should be no hard objects such as metal chips. First of all, what are the operating steps of the hose crimping machine? 1. Use a ruler to measure the length of the hose sample. Use a caliper to measure the metal joint data and observe the inner diameter of the hose sample. Prepare the required hoses and fittings. Use a pipe cutter to cut the hose to the desired length and clean the inner hole of the hose. 2. Use a peeling machine to peel off the outer rubber of the hose, and then insert the hose into the metal joint sleeve. The outer rubber of the hose must be peeled off. Insert the metal fitting straight into the hose all the way to the bottom. Measure whether the hose is the same length as the hose sample. Machine the hose with a non-taper shrink machine. Adjust the specified data by the positioner according to the hose to be crimped. 3. Start crimping the hose, either using the manual crimping button or using the foot crimping button. Snap the hose into place, then press the mold open button. After crimping, use a caliper to measure the crimping data. The hose can reach the specified withholding data. After the withholding is completed, stop the machine and cut off the power supply. Secondly, what matters should we pay attention to during the operation of the hose crimping machine? 1. Tighten the positioning screws before installing the module. Before starting the machine, lubricating oil should be injected into the inclined surface of the die base. It is strictly forbidden to use the oil cylinder over-travel. If it shakes during pressurization or depressurization, it is strictly prohibited to process it. If the cylinder piston vibrates or the oil pump makes a sharp noise, the gas should be discharged. 2. The pressure regulating valve should be adjusted to the specified pressure and calibrated regularly. It is strictly forbidden to put your hands on the crimping part when the equipment is running. The replacement of the mold should be carried out after the shutdown. When the temperature of the working oil exceeds 45°C, the machine should be stopped for inspection.

What Should Be Paid Attention To When The Hose Crimping Machine Fails

 release time : 2022-01--18  Traffic : 0

What Should Be Paid Attention To When The Hose Crimping Machine Fails It is absolutely essential that the hose crimping machine encounters failures during use. If you encounter some minor faults, friends who know some mechanical maintenance can probably solve them quickly, but once there are some major faults in the locking machine, it is not so easy to solve. Then it indicates that the locking machine may need an overhaul. So what elements should we pay attention to before overhauling? 1. Technical appraisal before overhaul At present, some overhauls of the crimping machine are mostly repairs to restore its performance. After the machine has been running for a long time, the aging of the main components and assemblies has reached the limit, so all the machines should be carried out. Dismantled, cleaned, inspected and repaired to make it perform to factory standards. Before the overhaul of the crimping machine, a technical appraisal shall be carried out, which shall be presided over by the technical person in charge of the user unit, with the participation of management, maintenance and drivers, and the pressure, flow, temperature and torque of the various parts of the machine before they are disassembled. Review technical files and operation records and other materials, examine the consumption of fuel and lubricants in detail, and make detailed records. Then compare with the relevant overhaul parameters provided by the original manufacturer to determine whether overhaul is required. The main technical conditions that determine whether a crimping hose machinery needs an overhaul are: (1) The engine power performance index drops by more than 20%; the oil consumption exceeds more than 1 times the rated value; the cylinder pressure of the engine does not reach 60% of the specified index when the temperature reaches 45 ℃ or more. (2) The wear of the main parts of the transmission mechanism has reached the limit, and there are phenomena such as yaw, abnormal noise, impact and jitter. (3) After the steering mechanism is worn, the clearance is too large, and the operation fails; the gears and shafts of the transmission are severely worn, and the gear shift is difficult or frequently skips; the braking mechanism is severely worn, and the braking performance decreases or fails, and cannot be adjusted. (4) The main body of the frame is deformed or cracked; the working device is seriously worn and the operation fails; the normal workload cannot be completed, or the operation accuracy cannot meet the requirements; the traveling mechanism is severely worn and cannot work normally. 2. Selection of overhaul method When the hose-crimping machine is overhauled in the factory, each part should be disassembled, measured, inspected and identified, and the wear detection of each part of each assembly, the cylinder liner, crankshaft, etc. of the engine should be carried out to obtain whether basis for replacement. Generally, the moving parts with greater wear and tear need to be replaced; for some parts that are inconvenient to replace, it is advisable to use welding repair, thermal spraying, electric brush plating and chrome plating to restore their original design dimensions. If the quality is not guaranteed, the parts to be replaced should be purchased from the original manufacturer or the designated cooperative manufacturer as required. Maintenance methods are divided into: on-vehicle repair and replacement assembly repair. The car repair method is to remove the parts from the machine in turn during the repair process, clean, test, classify and repair or replace them, and then reassemble them to restore performance. The on-vehicle repair method takes up a long time for downtime for repairs. Replacing the assembly repair method is that in the repair process, in addition to refurbishing the original frame, it is only necessary to remove all the remaining damaged assemblies or accessories and replace them with pre-prepared (or repaired) assemblies or accessories. , and then assembled into a complete machine repair method. This method can greatly reduce the repair time of downtime, which is beneficial to improve the repair work efficiency, reduce the cost and ensure the repair quality. This is also the most popular maintenance method in the American maintenance system, which is of great significance for the user to improve the integrity rate, utilization rate and production efficiency of mechanical equipment. 3. Precautions ⑴ Pay attention to eliminate potential safety hazards. During the overhaul process, attention should be paid to eliminating potential safety hazards, such as: adjusting the brake clearance, replacing the worn clutch friction plates and making the cab seat to be easily adjusted up and down, as well as eliminating some that are likely to cause injuries to drivers and maintenance personnel and machine failures security risks. Strengthen the driver's awareness of labor protection. When carrying out th

My Country's Hydraulic Machinery Crimping Machine Industry Has Broad Prospects For Development With the improvement of industrialization and automation level, these equipments need to be equipped with a large number of high-performance and high-reliability hydropneumatic and sealing components. According to preliminary calculations, it is estimated that by 2013, the total domestic demand for hydraulic, hydraulic, pneumatic and sealing products will increase from 20 billion yuan in 2005 (including about 900 million US dollars in imports and nearly 300 million US dollars in exports) to about 35 billion yuan (including about 30 billion yuan in exports). Imports are about 1.5 billion US dollars and exports are about 500 million US dollars). Among them, hydraulic products increased from more than 10 billion yuan to 20 billion yuan, hydraulic products increased from more than 1 billion yuan to more than 2 billion yuan, pneumatic products increased from nearly 3 billion yuan to more than 5 billion yuan, and sealing products increased from more than 3 billion yuan. Yuan increased to 7 billion yuan. construction machinery Construction machinery is the largest user of hydraulic products, accounting for 42.3% of industry sales, and the proportion will expand in the future, so the development trend of construction machinery is very important. It is estimated that by 2013, the annual demand for hydraulic excavators will be about 60,000 to 80,000 units, bulldozers (over 120 horsepower) will be nearly 10,000 units, loaders will be about 100,000 to 120,000 units, graders will be about 2,000 units, and road rollers will be about 1.5 million units. There are about 20,000 engineering cranes, about 80,000 forklifts, and nearly 10,000 cement mixers. In addition, my country now has about 1.4 million construction machinery, which is expected to reach 2 million by 2013. It is also reported that the hydraulic parts imported for the excavators, road machinery, cement mixers and other supporting facilities produced by domestic enterprises each year amount to more than 150 million US dollars. Weifang Yongfeng's hydraulic manufacturing share accounts for 30% of the country's total. In short, the market of hydraulic and seal parts for construction machinery and maintenance will face a new period of great development. These construction machinery products require a large number of high-performance and long-life crimping machines, pipe pressing machines, pipe locking machines, glue stripping machines, pressure testing machines, oil cylinders, cutting machines, etc. Metallurgical mining equipment It is understood that the utilization rate of hydraulic and pneumatic technology in metallurgical equipment reaches 6.1% to 8.1%, accounting for about 10% of the total equipment cost. From the analysis of industry statistics, hydraulic and pneumatic products directly provide support for the metallurgical industry, accounting for 14.5% and 9% of sales respectively (excluding retail sales). It is reported that the hydraulic, pneumatic and sealing products imported by the metallurgical industry for maintenance each year amount to tens of millions of dollars. Therefore, the demand for hydraulic and pneumatic seals for metallurgical and mining equipment supporting and maintenance will increase significantly. Metallurgical mining equipment will require a large number of plunger pumps, cartridge valves, solenoid valves, proportional valves, servo valves, oil cylinders, complete sets of hydraulic systems, pneumatic components and a large number of seals. By 2011, the annual demand for plastic machinery will reach about 150,000 units, of which injection molding machines account for about 40%. There are currently about 400,000 plastic machinery in my country, and it is expected to reach about 800,000 by 2013. Although the current development trend of small and medium-power injection molding machines using electric drives, according to analysis, in the next few years, due to plastic products and costs and other reasons, in addition to high-precision, high-efficiency, and high-quality products that require electric drives, my country will still have a large number of Apply fluid transmission. Therefore, the market demand for plastic machinery supporting, maintenance hydraulic, pneumatic and sealing parts will still maintain a rapid growth trend.

Parts Of The Hose Crimping Machine That Need Regular Maintenance The hose crimping machine produced by the withholding machine manufacturer not only moves smoothly and returns quickly, but also does not cause the phenomenon of spring return, which makes the mold unable to open and crimps. Moreover, the design of the cylinder crimping system is through the front and rear, which is easy to crimp various special-shaped elbows. The hydraulic system consists of a motor, an oil pump, a solenoid valve, a pressure regulating valve and a hydraulic valve to form a double hydraulic oil circuit with forward and backward movement, and a quick oil drain valve oil circuit is added to the double hydraulic oil circuit to achieve a faster return. bit purpose, with adjustable speed, noise and system pressure reduction. When crimping, the crimping speed should not be too fast, which will easily cause damage to the inner rubber and rupture of the steel wire layer, which will cause the hose to be damaged prematurely in use. In actual work, when replacing the high-pressure hose, the length of the hose, the number of steel wire layers, the shape and size of the joint should be reasonable, and the bending degree of the hose should be minimized. Most of the damage to the high-pressure hose is caused by improper production. . Check whether the protective device on the hose crimping machine is in good condition. If it is not installed properly, it is not allowed to drive the intermediate frequency hose pressing machine. It should have good grounding and electrical insulation, and the voltage should be stable. Check the lubricating parts of the hose crimping machine, and add enough oil when there is no oil or no oil. When crimping hoses of different specifications, the indenter of different specifications should be replaced. When oil leakage is found after long-term use, the seals in the oil cylinder and pipe valve system should be replaced in time. The hydraulic oil is 46# Great Wall brand anti-wear hydraulic oil, and the oil temperature is generally controlled at 30℃~35℃. Whether the pipe end is in good condition and the compression degree of the ferrule nut, etc., and at the same time eliminate the external force of the pipe. For flared pipe joints, most of them are caused by excessive flaring, unsatisfactory quality or repeated disassembly, resulting in flaring deformation or cracks, etc. If there is leakage, the front end can be cut off and re-flaring. If the male and female cone top pressure is used for sealing, the leakage is mostly due to the damage of the two cone surfaces. The cone surface can be ground with abrasive sand. In some cases, O-rings are used. For sealing by end face or outer diameter.

The Use Of Hose Crimping Machine In Greenhouse The technicians of the crimping machine will explain the application of the crimping machine in the greenhouse today; Greenhouse, also known as greenhouse, can transmit light, keep heat (or heat), and is used to cultivate plants. In the season that is not suitable for plant growth, it can provide growth period and increase yield, and is mostly used for plant cultivation or seedling raising of warm vegetables, flowers, forest trees and so on in low temperature season. So we can eat the vegetables we like in winter, and the greenhouse brings great convenience to people. Greenhouses can be divided into film greenhouses, glass greenhouses, and plastic plate greenhouses according to their materials. Among them, plastic greenhouses are commonly used. The main structure of plastic greenhouses generally uses hot-dip galvanized steel pipes as the main bearing structure, which is factory-produced and installed on site. The firmness of the greenhouse, the steel pipe plays a vital role, because the length and shape of the steel pipe used are different, the steel pipe needs to be inserted. The hose crimping machine uses pressure to crimp a section of the steel pipe to make it smaller, and insert it together with the other section of the steel pipe, so that the greenhouse skeleton structure can be stabilized. Regarding the way to reduce the outer diameter of the steel pipe by crimping, there are two ways, one is through thermal deformation, that is, the steel pipe is placed in a certain temperature environment, and the corresponding tooling is used for processing to make the outer diameter smaller. However, the processing cost of this method is relatively high and the efficiency is low. The other is cold extrusion deformation. The performance of our company's hose crimping machine is stable and reliable. It can crimp the steel pipe and the shape of the crimped steel pipe is neat, easy to install and disassemble, and the steel pipe can be reused.

The Crimping Machine Industry Rises From Innovation

 release time : 2022-01--10  Traffic : 0

The Crimping Machine Industry Rises From Innovation With the rapid development of China's economy, especially the large-scale expansion and explosion of the real estate industry, the entire construction machinery has been driven by sudden and rapid development, forming a blowout trend. As an important supporting equipment for the maintenance of construction machinery, the crimping machine has gradually become a favorite in the hearts of machinery users. Therefore, there are as many projects as there are large markets. The daily operation of the machine rumblingly brings about an increase in the market demand for maintenance and spare parts. Many businesses have also seized this opportunity to expand their scale, improve technology and expand their markets. In order to rapidly expand the market share, it has become an open secret in the industry to adopt methods such as rewarded sales, cash on delivery, and inferior accessories. This behavior directly leads to low equipment quality and lagging after-sales service. Excessive promotion of the vitality of the withholding machinery industry, although it can create some myths in the short term, will cause manufacturers to ignore technological innovation and process improvement; it also ignores product quality and service life, and ultimately affects the development of withholding machinery. With the slowdown and delay of infrastructure projects such as real estate and road and bridge construction, the crimping machine industry is affected by the decline in the overall economic growth rate. In the future, under the premise of maintaining overseas markets, we will increase the independent innovation of products and continue to improve the research and development of crimping machines and pipe pressing machines. Invest in efforts to create value for products and services and maintain a leading position in the industry. Construction machinery is the largest user of hydraulic products, accounting for 42.3% of industry sales, and the proportion will expand in the future, so the development trend of construction machinery is very important. It is estimated that by 2013, the annual demand for hydraulic excavators will be about 60,000 to 80,000 units, bulldozers (over 120 horsepower) will be nearly 10,000 units, loaders will be about 100,000 to 120,000 units, graders will be about 2,000 units, and road rollers will be about 1.5 million units. There are about 20,000 engineering cranes, about 80,000 forklifts, and nearly 10,000 cement mixers. In addition, my country now has about 1.4 million construction machinery, which is expected to reach 2 million by 2013. It is also reported that the hydraulic parts imported for the excavators, road machinery, cement mixers and other supporting facilities produced by domestic enterprises each year amount to more than 150 million US dollars. Weifang Yongfeng's hydraulic manufacturing share accounts for 30% of the country's total. In short, the market of hydraulic and seal parts for construction machinery and maintenance will face a new period of great development. These construction machinery products require a large number of high-performance and long-life crimping machines, pipe pressing machines, pipe locking machines, glue stripping machines, pressure testing machines, oil cylinders, cutting machines, etc.

 release time : 2022-01--09  Traffic : 0

How Does The Crimping Machine Work? The crimping machine firmly crimps the metal fittings on the matching high-pressure oil hoses for construction machinery or the brake hoses, oil hoses, air-conditioning hoses and power hoses of automobiles. The crimping machine is suitable for crimping various types of mechanical high and low pressure oil hoses, gas hoses, water hoses, cable fittings, automobile air conditioning hoses, automobile power steering hoses, oil hoses, gasoline fuel supply hoses, as well as building accessories and daily hot water gas hoses. It is widely used in Vehicles, construction machinery, hydraulic machinery, welding and cutting equipment and other industries. The working process of the crimping machine: The crimping mechanism is the working mechanism of the crimping machine. The pressure sleeve realizes reciprocating motion driven by the cylinder piston, and continuously compresses and relaxes the spring pressure head fixed on the front plate. Put the assembled joint into the appropriate position in the middle circular hole of the spring pressure head, start the motor, drive the oil pump to supply oil, control the direction of the electromagnetic reversing valve, drive the cylinder piston to move forward, and pass the pressure sleeve with the inner cone hole. , press the spring pressure head with the same taper to achieve the purpose of pressing. Press the mold opening button, the piston drives the pressure sleeve to move in the opposite direction, and the spring pressure head is restored. At this time, the hose fitting can be taken out from the crimping machine. In recent years, the withholding machine has entered the mature development cycle of the industrial life. In such an environment, all manufacturers are based on tradition, stick to the existing models, and lack the courage to reform and innovate. The adverse consequences are: the development of the entire industry appears. Insufficient stamina, lack of stamina for enterprise management and technology improvement. How to use the crimping machine: 1. Before starting the machine, add 50kg of 46# hydraulic oil to the crimping machine and the crimping machine at a time (preferably genuine original oil). 2. Connect the power supply, if you are using a three-phase motor, be careful not to connect it in reverse direction (top view: the motor fan rotates clockwise, one is forward rotation). 3. After the above process is completed, you can start the pressure test. 4. Use of crimping machine and crimping machine positioner: press 1mm more for each reverse rotation, and 0.01mm for each positive rotation, and so on, the same specification of hose and joint, the first metal joint reaches the required pressure, There is no need to move the positioner any more, keep pressing the specification, and the compressed data of the result is exactly the same. When you finish the pressure test of the first tubing, you have already learned it, and the rest is gradually proficient.

Briefly Describe The Functional Structure Of The Crimping Machine The crimping machine is a hydraulic automatic hose end processing machine controlled by the integrated control touch display screen to expand and shrink the end of the pipe under normal conditions. The replacement of the mold can expand, shrink, bulge, and upset the pipe. Wait for the hose end to be processed and shaped, and you can freely decide to use manual, inching or automatic processing according to user needs The machine tool is composed of oil tank, bed, slide block, main cylinder, mold core rod (optional), limit cylinder, compression cylinder, clamping mold, axial positioning cylinder, axial positioning angle iron and other main parts. Tube necking is a forming process that reduces the diameter of the end of the tube blank. The tube blank enters the deformation zone under the action of axial force, produces tangential shrinkage shrinkage plastic deformation in the deformation zone, and then enters the stable zone, Z eventually forms a reduced end diameter. Tube flaring is a forming process that enlarges the diameter of the end of the tube blank. The flaring shape can be tapered or cylindrical. The tube blank enters the deformation zone under the action of axial force, and produces tangential stretching in the deformation zone. The flaring is plastically deformed, and then enters the stable deformation zone, and Z is finally formed. The working speed of the main oil cylinder can be adjusted by setting a tubular throttle valve on the main oil cylinder circuit; a superimposed hydraulic control check valve is installed on the compression oil cylinder circuit to ensure that the mold does not become loose during clamping; shifting the oil cylinder , The limit oil cylinder and the axial positioning oil cylinder circuit are equipped with superimposed two-way throttle valves, which can adjust the two-way movement speed of the above-mentioned oil cylinders. Among them, the shifting oil cylinder and the limit oil cylinder are used in conjunction with the conversion station, so that the station conversion is convenient and accurate, and the processing quality of the hose fittings is ensured.

How To Choose Crimping Machine Products From Many Aspects The crimping machine is a combination of various engineering machinery, forming a device that integrates multiple purposes, and realizes one machine with multiple functions. The products on the market are good or bad, and so are the crimping machines. So when choosing a crimping machine, how do you choose a high-quality crimping machine? Here, the crimping machine manufacturer recommends three tips for everyone. Helped. Look: Observe visually whether the hydraulic accessories and electrical components selected by the crimping machine are brand-name products or are produced by regular manufacturers; whether the circuit configuration is regular; whether the design of the oil station piping is reasonable; whether there is oil leakage at the connection. If the above passes the visual inspection, you can proceed to the next step. Listen: Turn on the device after connecting it to the power source, and listen to whether the device's operating sound is normal. If there is abnormal noise, it is usually caused by the installation coaxiality of the motor and the oil pump. Another possibility is caused by the unreasonable selection of the oil pump displacement and pipe diameter, and the quality of the selected motor or oil pump. Not very well caused. Measurement: measure the main parameters of the equipment after Z Keep the crimping machine equipment in a dry running state, touch each module block with your hand, and there should be no jitter in the hand, otherwise it will be regarded as a substandard product. Install the crimping machine equipment on the mold, crimp a sample joint, measure the crimping joint with a caliper or a micrometer, the roundness and taper should be buckled within 0.1mm, which is considered excellent. The hardness of the mold base and the mold hardness are also the key to the normal use of the equipment in the future. Customers can request manufacturers to use a desktop or portable hardness tester to test the mold base or mold. When the hardness of the mold base is lower than Rockwell HRC60 and the mold hardness is lower than Rockwell HRC50, it will affect the withholding quality of the hose. After Z, it is to inspect the uniformity of the eight petals of the mold base of the equipment and the flushness of the mold. Good equipment will specifically control and adjust these two parameters, while some low-quality equipment does not control the above two parameters.

Crimping Operation And Preparation Of Crimping Machine The crimping machine is a kind of hydraulic equipment used to crimp the hose assembly in industrial production. It is suitable for crimping the high-pressure hose assembly in mechanical engineering. It applies the shrinking force to the matched metal joint through the mold of the crimping machine. What preparations do we need to make for safety and normal use? The crimping machine is a kind of hydraulic equipment used to crimp the hose assembly. It applies the shrinking force to the matched metal joint through the mold of the hose crimping machine, and firmly crimps the metal joint on the matched engineering machinery hose or automobile. Brake hoses, oil hoses, air conditioning hoses, power hoses. The crimping machine is suitable for the crimping of various mechanical high and low pressure oil hoses, air hoses, water hoses, cable joints, automobile air conditioning hoses, automobile power steering hoses, oil hoses, gasoline supply hoses, as well as construction accessories and daily hot water hoses. It is widely used Vehicles, construction machinery, hydraulic machinery, welding and cutting equipment and other industries. The oil pump of the crimping machine is installed in the oil tank and immersed in the hydraulic oil to achieve the purpose of scientific heat dissipation and mute design. The oil pump is driven by the motor to output hydraulic oil and push the plunger in the crimping cylinder to move, causing the mold base to shrink radially to realize the mold alignment. Squeeze the outer sleeve of the hose joint. When the shrinkage reaches the preset value of the micrometer, the extrusion stops automatically. After the electromagnetic reversing valve changes the direction, the plunger in the cylinder moves in the opposite direction, the mold opens, and the hose is crimped. The hose crimping machine should be crimped without load dozens of times when it is used for the first time. It can be used after observing that all parts are normal. The hose crimping machine should be crimped without load when used in winter to increase the oil temperature. Press the open button and mold After the base is opened, select the corresponding mold to install on the mold base according to the specifications of the clamped hose, and adjust the micrometer scale. Place the rubber tube with the joint in the proper position in the tube head, so that the entire length is crimped at one time, and press the crimp button to perform the crimping operation until the hose crimping head stops crimping and automatically opens the mold. Take out the crimped hose assembly, use a vernier caliper to check the outer diameter of the crimped joint jacket. If it does not match the parameter table, fine-tune the micrometer scale until the next hose crimp meets the requirements.

How To Choose The Right Crimping Machine

 release time : 2022-01--02  Traffic : 0

How To Choose The Right Crimping Machine More than 95% of current crimping machines provide power sources using hydraulic systems, which are occasionally used in low-pressure hose crimping machines or sanitary hose crimping machines that use pneumatic systems or levers to provide power. The oil pump of the hydraulic system is equivalent to the human heart, and its role is very important. Choosing gear pumps as the power source of the crimping machine often considers its low cost, cost-saving, and low requirements for oil cleanliness, but its shortcomings To provide a lower pressure, which is only equivalent to 60% of the pressure of the plunger pump. It is noisy and has a short lifespan. Due to the lower supply pressure, manufacturers often consider sacrificing the expansion and contraction capacity of the crimping machine in order to increase the crimping force. Improve the conversion of axial force and radial force of the crimping machine, so it is often possible to choose a gear pump crimping machine when the customer's requirements are not high. Using plunger pump as the power source of the crimping machine has the advantages of providing high pressure (300kg/cm2), long pump life, low noise, such as YCY series can automatically variable fuel supply, low pressure large flow, high pressure small flow, the same specifications The motor saves 30% of electricity and the hose that is crimped is not easy to leak oil. Because the system is high, it can be designed to achieve a larger opening under the same crimping pressure, so that customers can use it for a long time. But its disadvantages are: higher cost, the same displacement pump, the plunger pump is 8-10 times that of the gear pump, which increases the cost of a single machine, and requires relatively high oil cleanliness, but considering the basic performance Input-output ratio, choosing YCY system variable pump crimping machine will be very cost-effective.

Is there a limit to the crimping hose diameter of the crimping machine?

 release time : 2022-01--01  Traffic : 0

Is there a limit to the crimping hose diameter of the crimping machine? The crimping machine is an important auxiliary machine of the hose braiding machine, which is used in general hose production. It can effectively solve the problem of hose fitting sealing. The working principle of the crimping machine is to use high-strength liquid pressure to physically deform the connecting part of the hose fitting, so that the metal sleeve on the outside of the hose and the inner tube core are tightly combined, so as to achieve the function of sealing and leakproofing. Each crimping machine has restrictions on the diameter of the crimping pipe and the size of the nut. Generally speaking, the hose diameter suitable for the crimping machine is below 10cm. For the hose above 10cm, the crimping type hose connection is generally no longer used. Most of them are connected by hoop. Withholding range, the conventional is 6-51mm, withholding hose diameter 6-51mm spot supply is exported to the country's largest sales of 1.5 inch hose crimping machine, 2 inch hose crimping machine. Suitable for all kinds of mechanical high and low pressure oil pipes, air hoses, water hoses, cable joints, automobile air conditioning hoses, automobile power steering hoses, oil hoses, gasoline supply hoses, as well as construction accessories, daily hot water hoses, widely used in vehicles, High-pressure tubing presses, high-pressure tubing presses, construction machinery, hydraulic machinery, welding and cutting equipment and other industries. When the user is crimping the high-pressure hose, if the crimping amount is too small, and the pressure between the joint and the hose is too loose, the crimping hose may come out of the joint at the beginning of use under the action of oil pressure. If the crimping amount is too large, then If the joint and the hose are pressed too tightly, it is easy to cause local damage to the inner layer of the hose, causing cracks. The hydraulic oil will directly enter the steel wire layer from the rupture, and then leak out along the gap between the steel wires to the end of the outer jacket, or continue along the steel wire layer. It accumulates somewhere, causing the outer layer of glue to bulge or even break. When crimping, the crimping speed should not be too fast, which will easily cause damage to the inner rubber and breakage of the steel wire layer, which will damage the hose prematurely during use. In actual work, when replacing the high-pressure hose, the length of the selected hose, the number of steel wire layers, the shape and size of the joint should be reasonable, and the degree of bending of the hose should be minimized. Most of the damage of the high-pressure hose is caused by improper production. .

Matters Needing Attention In Daily Use Of Crimping Machine

 release time : 2021-12--28  Traffic : 0

Matters needing attention in daily use of crimping machine The use of crimping machines has been very common and extensive. There are certain operating procedures in the process of use. The crimping machine manufacturers need operators to be familiar with the entire related production process, and to be particularly familiar with the entire operating process of the crimping machine. Let's take a look at what are the operating steps and precautions during use? 1. When using the tube press for the first time, it should be crimped 20 to 30 times without load, and it can be used after observing that all parts of the ferrule pre-installation machine are normal. 2. When using the pipe press in winter, it should be withheld for 20 to 30 times without load to increase the oil temperature. 3. Press the open button, after the mold base is opened, select the corresponding mold to install on the mold base according to the specifications of the hose to be crimped, and adjust the micrometer scale (see the crimping parameter table for details). 4. Place the rubber tube with the joint in the proper position of the tube press, so that the entire length is crimped at one time. 5. Press the crimping button to execute crimping operation until the crimping head stops crimping and automatically opens the mold. 6. Take out the crimped hose assembly, use a vernier caliper to check the outer diameter of the connector jacket after the crimping machine. If it does not match the parameter table, fine-tune the micrometer scale until the next hose crimp meets the requirements. Precautions for crimping machine 1. When crimping, place the joint in the center of the mold as much as possible, and do not press on the hexagonal nut. 2. Prevent tools and other foreign objects from entering the press tube head. 3. Every time after the work is finished, the eight mold bases must be opened to the degree of Z, so that the spring can be in the opened state and the spring can be maintained, and the oil cylinder is also in the pressure relief state to extend the life of the oil seal.

Engineering noise reduction solution for hose cutting machine workshop Determination of the reverberation time and the noise value of each noise source in the hose cutting machine workshop Reverberation time means that the indoor sound reaches a stable state, and the sound source stops after the sound... Noise reduction engineering solutions for workshops 1. Determining the reverberation time of the hose crimping machine workshop and the noise value of each noise source. Reverberation time means that the indoor sound reaches a stable state. After the sound source stops sounding, the residual sound is reflected back and forth in the room and absorbed by the wall, and the average sound energy density drops to One millionth of the original value (or the time required for the sound energy density to attenuate 60dB). The longer the reverberation time, it means that the sound is reflected multiple times in the workshop, and the energy decay rate is slow. Under the same sound source, the workshop with long reverberation time will have more noise than the workshop with short reverberation time. 2. Selection of sound-absorbing materials Figure 6 shows the basic structure of the sound-proof board. It can be seen from the figure that the sound-proof board is composed of 5 parts. The noise enters the sound-absorbing cotton through the small holes of the perforated board. The energy is converted into heat and consumed, and the other part is isolated by the outer steel plate to achieve the purpose of absorption and sharing. (1) The outer steel plate with a thickness of 2mm plays the role of sound insulation and support, and is the outer surface of the sound-absorbing panel. (2) The middle part of the sound-absorbing board is made of sound-absorbing material, made of glass wool, which is used to absorb sound energy and is the main component of the noise-reducing material. It mainly includes two aspects. On the one hand, the thickness of the outer steel plate, especially in places where low-frequency noise is relatively large, the outer steel plate needs to be thickened, because the sound absorption effect of sound-absorbing cotton on low-frequency noise is far worse than that on high-frequency noise. Absorption; on the other hand, it is the choice of the thickness of the sound-absorbing cotton. Generally, according to the size of the noise, 50-100mm is a commonly used thickness range value. In this noise reduction project, the noise value exceeds the standard more. In order to ensure the noise reduction effect, Make sure that the thickness of the sound-absorbing cotton is 100mm. 3. Lighting treatment Since the interior of the equipment is isolated from the external workshop lighting after the implementation of the enclosed project, a lighting system needs to be added to the enclosed body. In order to ensure the lighting required for production and later equipment maintenance, the design illuminance reaches more than 500 lumens. The lighting system in the enclosed body is individually wired and switched independently to ensure convenient use and does not affect the original power supply system. In addition, in order to prevent sudden power outages in the workshop, an emergency lighting system was installed in the enclosure to ensure the safety of equipment and personnel.
