Integral step type multi-stage oil cylinder machining technology

Abstract

The invention provides an integral step type multi-stage oil cylinder machining technology and relates to the technical field of oil cylinder machining. The integral step type multi-stage oil cylindermachining technology comprises the following steps that S1, a thin-wall steel pipe and a thick-wall steel pipe are prepared; S2, the thin-wall steel pipe is machined into a step type multi-stage oilcylinder thin-wall part; S3, the thick-wall steel pipe is machined into a thick-wall step part; S4, welding forming is conducted on the thin-wall part and the thick-wall step part of a step type multi-stage oil cylinder in a friction welding manner; and S5, molded product inspection is conducted. According to the integral step type multi-stage oil cylinder machining technology, the thin-wall partof the step type multi-stage oil cylinder is machined by adopting the thin-wall steel pipe, the step part is machined by adopting the thick-wall steel pipe, and then the thin-wall part and the thick-wall part are welded and formed by adopting a friction welding technology. Compared with an existing technology, the production technology is relatively simple in machining manner, high in machining efficiency and low in technology cost, the loss of raw materials is less, and large-scale production and machining of enterprises are facilitated.

Description

technical field [0001] The invention relates to the technical field of oil cylinder processing, in particular to an integral stepped multi-stage oil cylinder processing technology. Background technique [0002] The oil cylinder is the hydraulic cylinder. The hydraulic cylinder is a linear motion executive element whose output force is proportional to the effective area of ​​the piston and the pressure difference on both sides. Its function is to convert hydraulic energy into mechanical energy. The input volume of the hydraulic cylinder is the fluid flow and Pressure, the output is the speed and force of linear motion. The piston of the hydraulic cylinder can complete the linear reciprocating motion, and the output linear displacement is limited. The hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy of reciprocating linear motion.

Problems solved by technology

[0003] At present, when processing step-type multi-stage oil cylinders, it is necessary to use thick-walled steel pipes for inner hole processing and reserve step lengths. The production process and processing methods are relatively complicated, the processing efficiency is low, the process cost is high, and the loss of raw materials is huge, so there are certain limitations. sex
