Manufacturing process of oil cylinder

Abstract

The invention relates to the technical field of oil cylinder manufacturing, and discloses a manufacturing process of an oil cylinder. The manufacturing process of the oil cylinder sequentially comprises the following process steps of blank forging, blank heat treatment, turning, laser strengthening, honing and the like, wherein the laser strengthening step comprises the operation of carrying out strengthening treatment on the surface of an inner hole of the oil cylinder by using a laser strengthening treatment device, the laser strengthening treatment device comprises a laser generator and a light guide main shaft connected with the laser generator, the front end of the light guide main shaft is provided with a laser output port perpendicular to the axis of the light guide main shaft, anda laser strengthening density controller used for achieving the interrupted strengthening on the surface of the inner hole of the oil cylinder is arranged at the laser output port. According to the manufacturing process of the oil cylinder, the surface quality of the inner hole of the oil cylinder is improved, the abrasion between the oil cylinder and a piston is reduced, and then the stability ofequipment application is improved.

Description

technical field [0001] The invention relates to the technical field of oil cylinder manufacturing, in particular to a manufacturing process of an oil cylinder. Background technique [0002] The oil cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It includes a cylinder body and a bottom plate connected to the end of the cylinder body, and its structure is relatively simple, and it is widely used in various mechanical equipment (such as engineering machinery, etc.). Conventional oil cylinders are classified according to their uses, including tensioning device cylinders for tensioning or tensioning, top pressure support cylinders for top pressure support, etc. [0003] Conventional oil cylinders in the prior art mainly have the following problems in use: [0004] One is that the surface of the inner hole of the oil cylinder has not been strengthened after processing, resulting i...

AI Technical Summary

Problems solved by technology

[0004] One is that the surface of the inner hole of the oil cylinder has not been strengthened after processing, resulting in a limited service life, especially the inner hole surface of the oil cylinder with high frequency of use wears faster

[0005] The second is uneven wear on the surface of the inner hole of the oil cylinder. On the one hand, this uneven wear leads to a decline in the performance of the oil cylinder, and on the other hand, it reduces the stability of the equipment in use, and even causes vibration of the equipment, thereby reducing the reliability of the equipment.

[0006] The third is that for some oil cylinders that require high matching precision with the piston, due to the very small fit clearance, it is easy to cause bite between the piston and the oil cylinder, thus accelerating the wear between the piston and the oil cylinder
