Abstract

The invention discloses a process for processing a cylinder block of a hydraulic cylinder. The method comprises the following steps: A: selecting seamless steel pipe as the material of the hydraulic cylinder; B: cutting and blanking the seamless steel pipe by a sawing machine; C: cutting and blanking the seamless steel pipe Quenching and carburizing treatment, after quenching and carburizing, check the hardness of the seamless steel pipe; D: lathe the outer circle of the seamless steel pipe, process thread, end face and chamfer; E: first rough the seamless steel pipe Boring, followed by semi-finish boring, then fine boring of seamless steel pipes, and finally fine reaming of seamless steel pipes; F: use rolling head to roll the holes obtained after deep hole push boring; G: Turning process thread, turning outer circle steps; H: taper hole and turning end face; I: drilling and tapping; J: checking the dimensional accuracy and surface roughness of the hydraulic cylinder; in general, the present invention has reliable quality , Long service life and good wear resistance.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a hydraulic cylinder body processing technology. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. Its structure is simple, and it is easier to manufacture compared with other more complex parts. It is suitable for mass production, with low production cost and wide application range. However, the current processing technology is prone to low-quality hydraulic cylinders, rapid wear and short service life. Therefore, in order to effectively solve the above problems, a processing technology for hydraulic cylinder cylinder...
