Grinding process of vibration reducer piston rod

Abstract

The invention discloses a grinding process of a vibration reducer piston rod. The grinding process comprises the steps of: (1) performing the first rough grinding form a molded piston rod rough blank; (2) quenching the piston rod after the first rough grinding; (3) straightening the quenched piston rod; (4) performing the second rough grinding for the straightened piston rod; (5) performing the finish turning for the piston rod after the second rough grinding; (6) performing the semi-finish grinding for the piston rod after the finish turning; (7) polishing the piston rod after the semi-finish grinding; (8) electroplating the polished piston rod; (9) performing the ultra-finish grinding for the electroplated piston rod; and (10) performing the UB grinding wheel polishing for the piston rod after the ultra-finish grinding. The grinding process can largely improve the surface quality of the vibration reducer piston rod, can prolong the service life of the piston rod, and can improve the use precision of a vibration reducer.

Description

Technical field: [0001] The invention relates to the technical field of shock absorber piston rod processing, in particular to a grinding process capable of improving the surface precision of the shock absorber piston rod. Background technique: [0002] At present, various manufacturers usually use polishing before electroplating when producing shock absorber piston rods, and use ordinary grinding wheels such as resin. This kind of processing makes the surface roughness of the piston rod only reach about 0.1. The size is not uniform, and in the long-term continuous operation, it will also produce scratches and heat to reduce the hardness of the surface. Therefore, the surface quality of the piston rod processed by this processing technology is relatively poor, the service life is short, and it will also affect the shock absorption. The use accuracy of the device. Invention content: [0003] The object of the present invention is to provide a shock absorber piston rod grin...
