release time : 2021-09--20 Traffic : 0
How to install and debug the crimping machine and matters needing attention The crimping machine is suitable to be transported by a forklift, and the pressure is applied to the bottom of the pipe press. The crimping machine is strictly prohibited from inverting. It is specially added to raise the hand, which is convenient for users who do not have a forklift to carry it at will. It is strictly forbidden to lift the head of the buckle tube, motor and electrical box. The selected mold refers to the plastic tube to be crimped. If you are not satisfied after crimping, adjust the micrometer and crimp a hose. When crimping the hose joint: Too much crimping size, the rubber layer in the hose is crushed, causing oil leakage; too little crimping size, causing oil leakage and being hydraulically flushed out of the joint. Be sure to grasp a reasonable degree of crimping, subject to the shrinkage of the inner hole of the connector core. Precautions for pipe press 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 head. 3. After each work is completed, the eight mold bases must be opened to the maximum extent, so that the spring can be in an open state and the spring can be maintained, and the oil cylinder is also in a pressure relief state to extend the life of the oil seal. The hose crimping equipment produced by the crimping machine manufacturer deforms the metal joint under pressure, so as to steadily and accurately crimp the hose on the special equipment, such as (hydraulic machinery, excavators, loaders, cranes, automobile air-conditioning pipes) , It is the necessary equipment for hydraulic machinery factory and excavator maintenance point. This pipe press module adopts double inclined surface design, with increased buckle pressure, no taper, long service life, low noise, small size, light weight, multiple functions, fast mold opening, easy operation, and easy maintenance. The plunger pump is installed in the oil tank and soaked in the hydraulic oil to achieve the purpose of scientific heat dissipation and mute design. The plunger pump is driven by the motor to output hydraulic oil and push the plunger in the withholding cylinder to move, causing the mold base to shrink radially to realize the mold. 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.

release time : 2021-09--16 Traffic : 0
Introduction to the fault and troubleshooting of the crimping machine With regard to the permanent mechanical precision and life of the crimping machine, not only high-quality alloy steel materials are selected for the locking organization components, but also a unique heat treatment process is selected. Therefore, the longer service life of the pressure tube is inseparable from the material selection, heat treatment, machining, installation and structure rationality. 1. When the machine is used for the first time, it should be withheld for 20 to 30 times, and it can be used after investigating that all parts are normal. The pipe locking machine should be crimped 20-30 times without load in winter to increase the oil temperature. 2. Press the mold opening button to open the mold base. Select the corresponding mold device on the mold base and adjust the scale of the ruler according to the standard of the hose to be crimped. (See the technical parameter reference table for details) 3. Press the mold opening button and take out the crimped hose assembly. Use a vernier caliper to check the outer diameter of the crimped pipe sleeve. If the crimped diameter does not match the parameter table, you should fine-tune the scale of the ruler and repeat the above operation until it meets the requirements. 4. Put the rubber tube with the joint in the proper position in the lock, so that the whole length can be crimped at one time. 5. Press the crimping button to perform the crimping operation until the lock head stops crimping. The cylinder piston of the crimping machine is made of integrated fine cast steel to completely solve the cylinder deformation caused by welding, and the product accuracy cannot be reached. The advance and retreat of the piston and the opening and contraction of the mold are all driven by the hydraulic power source. . It not only moves steadily and returns quickly, but also does not cause the phenomenon that the mold cannot be opened and locked like a tension spring returning to its position. In addition, the cylinder locking system is designed to run through the front and back, which makes it easy to withhold various special-shaped elbows.

About the related functions of the crimping machine

release time : 2021-09--15 Traffic : 0
About the related functions of the crimping machine First of all: Let's talk about the working mechanism of the tube crimping machine: the compression sleeve is driven by the cylinder piston to achieve reciprocating motion. The crimping machine manufacturer continuously compresses and relaxes the spring pressure head fixed on the front plate. Put the assembled connector into the appropriate position in the middle round hole of the spring pressure head, turn on the motor, drive the oil pump to supply oil, and control the electromagnetic reversing valve to drive the cylinder piston to move forward through 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 joint can be taken out of the shrinking machine. The most commonly used are: hydraulic, numerical control, etc. There is no national standard for the pipe locking machine for the time being. Related national standards for hydraulic hose joints: GB/T 9065.1-1988 hydraulic hose joint connection size flared type GB/T 9065.2-1988 hydraulic hose joint connection size card sleeve type GB/T 9065.3-1988 hydraulic hose joint connection size welding type or quick change type The function of the tube locking machine oil seal is simply to seal the oil, and the purpose is to prevent the oil inside the tube locking machine from leaking. The oil is a necessary liquid substance in the system, so the oil seal plays a key role in the tube crimping machine. More than 95% of today's pipe shrinking machines use hydraulic systems, and they are occasionally used in low-pressure oil pipe shrinking machines or sanitary pipe shrinking 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 a gear pump as the power source of the tube shrinking machine often considers its low cost, cost saving, and low requirements for oil cleanliness. The disadvantages are: low supply pressure, which is only 60% of the pressure of the plunger pump, high noise and short lifespan. Due to the low supply pressure, manufacturers often consider sacrificing the expansion and contraction capacity of the tube shrinking machine in order to increase the buckle pressure. .

In the seasons that are not suitable for plant growth, it can provide growth period and increase yield. It is mostly used for plant cultivation or seedling cultivation of temperature-loving vegetables, flowers, forests, etc. in low temperature seasons. So we can eat the vegetables we like to eat in winter, and the greenhouse brings great convenience to people. Greenhouses can be divided into thin-film greenhouses, glass greenhouses, and plastic greenhouses according to their materials. Among them, plastic greenhouses are the most commonly used. The main structure of plastic greenhouses generally uses hot-dip galvanized steel pipes as the main bearing structure, factory production, and on-site installation. Steel pipes play a vital role in the firmness of greenhouses. Because of the different lengths and shapes of steel pipes, they need to be connected. The hose crimping machine uses pressure to crimp one steel pipe to a smaller size, and insert it with another steel pipe to make the greenhouse skeleton structure stable. Regarding the steel pipe crimping to make the outer diameter smaller, there are currently 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 steel pipes and the resulting steel pipes are neat in shape, easy to install and disassemble, and the steel pipes can be reused.

However, the processing cost of this method is relatively high and the efficiency is low.   The appearance of this machine broke the long-term monopoly of the domestic market by international products on this series of machines. This machine was just off the assembly line, and it was bought by a Ningbo customer, and another 5 units were ordered on the spot. After the machine has been used for a long time by customers, the effect of withholding fully meets the needs of customers. The machine is of good quality, high precision and reasonable price. Welcome new and old customers to come to consult and negotiate! 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 circuit with forward and retreat movement, and a quick drain valve circuit is added to the dual hydraulic circuit to achieve faster return. The purpose of the position, and the speed is adjustable, the noise and the system pressure are reduced. 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 longer service life of the crimping machine is inseparable from the rationality of material selection, heat treatment, machining technology and structure!

How to use the hose crimping machine correctly? The structure of the steel pipe shrinking machine: Weld a site with channel steel, and the power end is equipped with a motor, a reducer, and a chuck (for pipe clamping, it can be replaced by a lathe chuck). A support base (openable) is installed at the other end, and a heating ring is fixed on the outer end of the support base (8-10 nozzles, welded to a copper pipe ring by gas welding by grabbing the nozzle). On the outermost side is a movable bracket on which an alloy mold is installed. After years of research and development by R&D personnel, a new generation of fully automatic hose crimping machine has been developed and produced through changing methods. The advance and retreat of the piston and the opening and contraction of the mold rely on the power generated by the hydraulic power source. It not only moves smoothly and returns quickly, but also does not cause the mold to be locked due to the spring return. Moreover, the design of the cylinder locking system is through front and back, which is easy to withhold various special-shaped elbows, and finally meet the forming requirements. The hose crimping machine uses pressure to crimp one steel pipe to a smaller size, and insert it with another steel pipe to make the greenhouse skeleton structure stable.

If the crimping machine is hot, the foot switch should be reset first, and the machine should be turned on after shutting down for 2 minutes

release time : 2021-09--02 Traffic : 0
If the crimping machine is hot, the foot switch should be reset first, and the machine should be turned on after shutting down for 2 minutes It is important to have a reasonable heat dissipation area to keep the oil temperature within a reasonable range. Generally, if the crimping machine is overheated, it is necessary to check whether the heat dissipation area of ​​the electrical circuit of the crimping machine is working normally. The surface temperature or noise of the servo motor or variable frequency motor is often tested, and it is necessary to deal with it in time. When the system load changes, simply control the oil to maintain a stable temperature. It is necessary to install a cooling device. Outside dust, sand, etc., friction will also generate heat during the operation of the crimping machine, and the leaking oil flowing back to the oil tank will enter the hydraulic oil. In addition, when repairing, a little carelessness will also cause magazines and so on to enter the hydraulic oil. The crimping machine itself also continuously generates dust and dirt, which directly enters the hydraulic oil, such as wear particles of metal and sealing materials, fallen particles or fibers, and gelatinous substances generated by the oxidation and degeneration of the oil due to the increase in oil temperature. The principle of the withholding machine is not far away. If the liquid passes through the inside of the pressure gauge, it will also have a pressure. If this pressure gauge is working for a long time, the original is that the pressure of the liquid must be continuously operated on the pressure gauge. It is necessary to know how large the pressure of the liquid is, so it will not have a serious impact on the crimping machine. Users should understand the rules and regulations and safe operation procedures, master the sequence of turning on and off the crimping machine, and understand and master the structural principle of the crimping machine. Some users of crimping machine will feel the machine is hot during use. In order to make the crimping machine overload for a long time, open the crimping machine to dissipate heat. This is a wrong method, which will eventually cause the crimping machine to fail. Speed ​​up the damage.

Do you know the working principle of the crimping machine The principle of dual hydraulic circuit operation is adopted, that is, the advance and retreat of the piston and the opening and contraction of the mold are all driven by the hydraulic power source. It not only moves steadily and returns quickly, but also does not cause the phenomenon of a spring to return, which prevents the mold from being opened and locked. Moreover, the design of the cylinder locking system is through front and back, which is easy to withhold various special-shaped elbows. 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 longer service life of the crimping machine is inseparable from the rationality of material selection, heat treatment, machining technology and structure! The oil pump 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 withholding cylinder to move, causing the mold base to shrink radially, realizing the mold to the hose joint cover Squeeze. 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 seat is opened, and the hose is crimped. Pipe press maintenance 1. The hydraulic oil should be replaced in time. 2. Frequently inject anti-wear hydraulic oil into the moving surface of the mold base. 3. During the non-pressing time, please cover the dust cover to prevent debris from falling into the mold base.

What are the problems that the operators of the hose crimping machine easily overlook? The principle of dual hydraulic circuit operation is adopted, that is, the advance and retreat of the piston and the opening and contraction of the mold are all power generated by the hydraulic power source. It not only moves steadily and returns quickly, but also does not cause the phenomenon of a spring to return, which makes the mold not open and locks up. Moreover, the design of the cylinder locking system is through front and back, which is easy to withhold various special-shaped elbows. 1. First, check whether the hydraulic accessories, electrical components, oil pumps, and motors selected by the hydraulic crimping machine can be produced by the on-track manufacturer; whether the circuit configuration is orderly; whether the oil circuit design is reasonable and natural; whether there are pipeline connections Oil seepage phenomenon. 2. Turn on the crimping machine after it is connected to the power supply, and listen to the running sound of the machine. If there is abnormal noise under normal conditions, it is often caused by the coaxiality of the motor and the oil pump device. It may also be caused by the mismatch of the oil pump displacement and the pipe diameter design choice. The most serious problem is the selected motor or oil pump. Caused by quality. 3. Keep the hydraulic crimping machine in an idling state, touch the eight-leaf seat module with your hand, there should be no violent vibration in the hand, otherwise it will be regarded as a substandard product. With its performance, hose crimping machines are used in construction machinery, vehicles, hydraulic machinery, welding and cutting equipment and other industries, and are favored. In the process of use, the operator can easily overlook some operating procedures:  1. The operator must operate in accordance with the process regulations.  2. The power supply must be cut off after the machine is stopped.  3. When changing the mold, it must be done after the shutdown.  4. The joint surface of the mold seat and the mold should be kept clean, and there should be no hard objects such as metal shavings.  5. Pour lubricating oil on the inclined surface of the mold base before starting the machine.  6. The positioning screws must be tightened before installing the module.  7. The pressure regulating valve must be adjusted under the specified pressure.

Repair and maintenance of crimping machine Repair and maintenance of crimping machine 1. Working principle of the pipe press The oil pump 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 withholding cylinder to move, causing the mold base to shrink radially, realizing the mold to the hose joint cover Squeeze. 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. 2. Installation and commissioning of the pipe press Handling: The pipe press is suitable to be transported by a forklift, and the pressure is applied to the bottom of the pipe press. The pipe press is strictly prohibited from inverting. It is strictly forbidden to lift the pressure pipe head, motor and electrical box. Installation: The pipe press must be placed horizontally on a stable foundation and grounded. Oil filling: Open the oil tank cover and add 68# anti-wear hydraulic oil to the 2/3 position of the oil level gauge. Electricity connection: Connect the power cord to the power supply specified by the tube press, start the motor and observe the direction of rotation. The direction of the motor should be consistent with the direction marked by the motor. If the direction of the motor is inconsistent with the marked direction, please change the position of two of the power cords. Micrometer: It is used to adjust the shrinkage of the crimping hose. It is 1mm more in the counterclockwise half a week, and 1mm less than the clockwise half a week. Pressure adjustment: The maximum pressure of the pipe press system is 31.5Mpa, which is adjusted by the overflow valve. The clockwise adjustment pressure increases, and the counterclockwise adjustment pressure decreases (it has been adjusted at the factory, and can be adjusted by itself if necessary). Mold opening speed adjustment: the speed of mold opening speed is controlled by the diverter valve. It is adjusted clockwise, the opening speed is increased, and the counterclockwise adjustment is adjusted. The best value is not more than 10Mpa (it has been adjusted before leaving the factory, you can adjust it yourself if necessary). Three, withholding operation 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 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. 4. Place the hose with the joint in the proper position in the press head, 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 and 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 crimping of the next hose meets the requirements. Four, pressure tube test example Crimping Ф19mm four-layer steel wire hose (Italian Manuli 4sp standard) From the hydraulic tubing crimping parameter table, it is found that the outer diameter of the Ф19mm four-layer steel wire hose joint jacket is 37mm before crimping and 33.5mm after crimping. The inner diameter of the mold should be Ф33mm, and the corresponding micrometer scale is 3. Install the Ф33mm mold on the mold base, rotate the micrometer scale to 3 places, peel the rubber tube and assemble it with the joint. After the crimping is completed, the outer diameter of the connector jacket is measured to be the crimped value 33.5mm in the crimping parameter table, and then the crimping is completed. If the outer diameter does not match after crimping, trim the micrometer and crimp a hose. When crimping the hose joint: Too much crimping size, the rubber layer in the hose is crushed, resulting in oil leakage; too small crimping size, causing oil leakage and being flushed out of the joint by hydraulic pressure. Be sure to grasp a reasonable degree of crimping, based on the shrinkage of the inner hole of the connector core, the compression of the national standard connector is 0.1~0.4mm, and the compression of the ordinary connector is 0.1~2mm. Due to the different manufacturers of hoses and joint jackets, for example, most hose manufacturers in the north use GB standards, the south uses 602 standards, and foreign SAE standards.

Application of hose crimping machine in greenhouse

release time : 2021-08--05 Traffic : 0
Application of hose crimping machine in greenhouse Greenhouse is also called a greenhouse that can transmit light and keep warm (or heat), and is used to cultivate plants. In the seasons that are not suitable for plant growth, it can provide growth period and increase yield. It is mostly used for plant cultivation or seedling cultivation of temperature-loving vegetables, flowers, forests, etc. in low temperature seasons. So we can eat the vegetables we like to eat in winter, and the greenhouse brings great convenience to people.        Greenhouses can be divided into thin-film greenhouses, glass greenhouses, and plastic greenhouses according to their materials. Among them, plastic greenhouses are the most commonly used. The main structure of plastic greenhouses generally uses hot-dip galvanized steel pipes as the main bearing structure, factory production, and on-site installation. Steel pipes play a vital role in the firmness of greenhouses. Because of the different lengths and shapes of steel pipes, they need to be connected.        The hose crimping machine uses pressure to crimp one steel pipe to a smaller size, and insert it with another steel pipe to make the greenhouse skeleton structure stable. Regarding the steel pipe crimping to make the outer diameter smaller, there are currently 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 steel pipes and the resulting steel pipes are neat in shape, easy to install and disassemble, and the steel pipes can be reused. After years of research and development by R&D personnel, a new generation of fully automatic hose crimping machine has been developed and produced through changing methods. The advance and retreat of the piston and the opening and contraction of the mold rely on the power generated by the hydraulic power source. It not only moves smoothly and returns quickly, but also does not cause the mold to be locked due to the spring return. Moreover, the design of the cylinder locking system is through front and back, which is easy to withhold various special-shaped elbows, and finally meet the forming requirements. Through this innovation, the problem of fast crimping speed and high precision of the fully automatic crimping machine has been realized in a true sense. Realize the compact structure of the equipment, reasonable assembly process, one machine with multiple functions, which can complete low-pressure oil pipes, air pipes, water pipes, cable joints, automobile air conditioning pipes, automobile power steering pipes, engine oil pipes, gasoline fuel supply pipes, as well as construction accessories and daily heating The withholding of water and gas pipes provides users with more sources of raw materials and a variety of products to meet the needs of various users.

The inner diameter of the mold should be Ф33mm, and the corresponding micrometer scale is 3. install Install the Ф33mm mold on the mold base, rotate the micrometer scale to 3 places, peel the rubber tube and assemble it with the joint. After the crimping is completed, the outer diameter of the connector jacket is measured to be the crimped value 33.5mm in the crimping parameter table, and then the crimping is completed. If the outer diameter does not match after crimping, trim the micrometer and crimp a hose. When crimping the hose joint: Too much crimping size, the rubber layer in the hose is crushed, resulting in oil leakage; too small crimping size, causing oil leakage and being flushed out of the joint by hydraulic pressure. Be sure to grasp a reasonable degree of crimping, based on the shrinkage of the inner hole of the connector core, the compression of the national standard connector is 0.1~0.4mm, and the compression of the ordinary connector is 0.1~2mm. Due to the different manufacturers of hoses and joint jackets, for example, most hose manufacturers in the north use GB standards, the south uses 602 standards, and foreign SAE standards.

Debugging of crimping machine and answers to common questions

release time : 2021-07--29 Traffic : 0
Debugging of crimping machine and answers to common questions In the process of installation and commissioning of the crimping machine, there are many details that need to be paid attention to. The main items to be paid attention to are handling, installation, micrometer, pressure adjustment, oil injection, power connection, and mold opening speed adjustment. 1. Handling: The pipe pressing machine is suitable for forklift handling, and the pressure is applied to the bottom of the pipe pressing machine. The crimping machine is strictly forbidden to be inverted. It is strictly forbidden to lift the pressure pipe head, motor and electrical box. 2. Installation: The pipe press must be placed horizontally on a stable foundation and grounded. Wuzhou hydraulic: precautions for installation and debugging of pipe press 3. Micrometer: It is used to adjust the shrinkage of the crimping hose. It is 1mm more in the counterclockwise half a week, and 1mm less than the clockwise half a week. 4. Pressure adjustment: The maximum pressure of the pipe press system is 31.5Mpa, which is adjusted by the overflow valve. The clockwise adjustment pressure increases, and the counterclockwise adjustment pressure decreases (it has been adjusted at the factory, and can be adjusted by itself if necessary). Wuzhou hydraulic: precautions for installation and debugging of pipe press 5. Oil filling: Open the oil tank cover and add 68# anti-wear hydraulic oil to the 2/3 position of the oil level gauge. 6. Connecting to electricity: Connect the power cord to the specified power source of the pipe crimping machine, start the motor and observe the direction of rotation. The direction of the motor should be consistent with the direction marked by the motor. Wuzhou Hydraulics: Precautions for installation and debugging of the pipe press If the rotation of the motor is inconsistent with the marked direction, please change the position of two of the power cords. 7. Mold opening speed adjustment: The mold opening speed is controlled by the diverter valve and adjusted clockwise. The opening speed is increased, and the opening speed is adjusted counterclockwise. The opening speed is slowed down, but too fast opening speed will increase the noise. , The best value is not more than 10Mpa (it has been adjusted before leaving the factory, you can adjust it yourself if necessary). The installation and commissioning of the pipe press cannot be ignored. Perhaps it is this sloppy that causes the quality of the pipe press to be reduced and the life span is shortened, which will directly affect the benefit of the enterprise. Common failure phenomena of pipe presses Possible causes   elimination method 　　 The motor does not rotate after the tube press is energized, and the power supply has no power 1. Check whether the power switch is off. 　　 2. Check whether the contactor is closed. 　　 3. Check whether the fuse is blown. 　　 4. Check whether the thermal relay is disconnected. The motor rotates, 　　 But it doesn't work. The power supply lacks phase. 1. Check whether the fuse is blown. 　　2. Check whether all three wires are energized. Motor reverse rotation 1. Reverse any two phases of the three-phase power supply. The locking nut of the pressure regulating valve is loose 1. After the pressure regulating valve is tightened one turn, the nut is locked. Insufficient amount of hydraulic oil 1. Check whether the oil level is at the liquid level line. The electromagnetic reversing valve does not operate

The maintenance of the crimping machine and its daily failure maintenance

release time : 2021-07--28 Traffic : 0
The maintenance of the crimping machine and its daily failure maintenance When crimping the crimping machine, place the joint in the center of the mold as much as possible, and do not press on the hexagonal nut. Prevent tools and other foreign objects from entering the press head. Each time after the work is completed, the eight mold bases must be opened to the maximum extent, so that the spring can be in an open state and the spring can be maintained, and the oil cylinder is also in a pressure relief state to extend the life of the oil seal. The most important steps for the operation of the crimping machine Maintenance of the pipe press: The hydraulic oil in the oil tank should be replaced when it exceeds the time limit specified by the hydraulic oil manufacturer, or the oil level gauge should be checked visually. If the hydraulic oil is oxidized and darkened, it must be replaced. Frequently inject anti-wear lubricant into the moving surface of the mold base. During non-pressing machine working hours, please cover the dust cover to prevent debris from falling into the mold base Hose crimping machine is a kind of special hydraulic equipment that rivets high-pressure hose and metal pipe joints together by cold extrusion. According to the structure, it is divided into: four-post crimping machine, ram crimping machine and ring crimping Three kinds of machines. Among them, the ring crimping machine is popular in the market because of its simple structure, small size, material saving, low price, and high power conversion rate. However, the ring crimping machine also has its shortcomings. The tapered layer of the crimped workpiece will peel off and will enter the cylinder block and the working surface of the mold base along the eight expansion joints of the eight-part mold base, and it is not easy to clean, although it is through the opening of a chip hole at the front end of the cylinder and an additional installation in front of the piston Measures such as non-standard dust-proof ring still cannot cure the scratches on the inner wall of the cylinder and the working cone of the mold base.  The choice of anti-wear hydraulic oil in the crimping machine and pipe pressing machine is good or bad, which has a great impact on the working efficiency and service life of the equipment. It can be said that it is an invisible hazard in the crimping machine and the pipe pressing machine. Developed on the basis of anti-oxidant hydraulic oil, it has alkaline high zinc, alkaline low zinc, neutral high zinc type and ashless type products. They are all divided into 22, 32, and 32 according to the 40'C kinematic viscosity. 46 and 68 four grades. The crimping machine and the pipe pressing machine use No. 46 anti-wear hydraulic oil. When crimping with crimping machine and pipe crimping machine, the crimping speed should not be too fast, which can easily cause damage to the inner rubber and breakage of the steel wire layer, and cause premature damage to the hose 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. .

Remember three points in the operation of the crimping machine With its performance, the crimping machine is used in construction machinery, vehicles, hydraulic machinery, welding and cutting equipment and other industries, and has been favored. In the process of use, the operator can easily overlook some operating procedures: 1. The operator must operate in accordance with the process regulations. 2. The power supply must be cut off after the machine is stopped. 3. When changing the mold, it must be done after the shutdown. 4. The joint surface of the mold seat and the mold should be kept clean, and there should be no hard objects such as metal shavings. 5. Pour lubricating oil on the inclined surface of the mold base before starting the machine. 6. The positioning screws must be tightened before installing the module. 7. The pressure regulating valve must be adjusted under the specified pressure. 8. It is strictly forbidden to reach inside when working. 9. The electrical safety regulations must be observed when overhauling electrical parts Whether the operation of the crimping machine is correct and reasonable is related to the quality of the crimping, so we will share the three points of attention to the operation of the crimping machine. 1. When crimping, prevent tools and other foreign objects from entering the crimping head. 2. When crimping, place the joint in the center of the mold as much as possible, and do not press on the hexagonal nut. 3. After the work is completed, the eight mold bases must be opened to the maximum extent, so that the spring can be in an open state and the spring can be maintained, and the oil cylinder is also in a pressure relief state to extend the life of the oil seal. The staff abide by the operating precautions of the three-point crimping machine to better achieve the crimping effect.
