Oil way system of crimping machine and oil way control method thereof

Abstract

The invention provides an oil way system of a crimping machine and belongs to the technical field of hydraulic transmission. By means of the oil way system, the problem that an existing oil way system of a crimping machine is low in work efficiency is solved. The oil way system of the crimping machine comprises an oil pump, an oil cylinder and an oil tank used for storing oil. The oil pump is arranged in the oil tank and connected with a motor, and the motor can drive the oil pump to pump out the oil in the oil tank. The oil pump and the oil cylinder are communicated through an electromagnetic reversing valve, a booster for increasing the pressure of the oil way system is arranged between the electromagnetic reversing valve and the oil cylinder, and the booster is communicated with the electromagnetic reversing valve and the oil cylinder. The invention further provides an oil way control method of the oil way system of the crimping machine. The oil way system has the advantages that the structure is simple, and oil input and return are rapid.

Description

technical field [0001] The invention belongs to the technical field of hydraulic transmission, and relates to an oil circuit system of a crimping machine and an oil circuit control method thereof. Background technique [0002] The crimping machine is a kind of hydraulic equipment used for crimping the pipe fitting assembly. It applies shrinkage force to the matching metal joint through the mold of the crimping machine, and firmly crimps the metal joint on the high-pressure oil pipe for the supporting construction machinery or the car. Brake pipes, oil pipes, air-conditioning pipes, power pipes, widely used in vehicles, construction machinery, hydraulic machinery, welding and cutting equipment and other industries. [0003] Different industries and different products have different requirements for the crimping speed, crimping pressure and other parameters of the crimping machine.

AI Technical Summary

Problems solved by technology

[0003] Different industries and different products have different requirements for the crimping speed, crimping pressure and other parameters of the crimping machine. The crimping machine is driven by a hydraulic system. For different crimping jobs, it is necessary to set up corresponding oil pumps, oil circuit systems, etc. etc. There are many equipments and the system is relatively complicated, so the work efficiency is not high enough, which often leads to the extension of the work cycle, which is not conducive to the continuous withholding work

[0004] In addition, for some working mechanisms with high local working pressure, the driving components with a fixed pressure range cannot meet their needs, resulting in the failure of related work to be carried out smoothly
