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.
