The Crimping Machine Industry Rises From Innovation

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.

How Does The Crimping Machine Work?

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

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

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.

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.
