Abstract

The invention discloses a machining method of a powder metallurgy cross slip ring die. The method comprises steps of processing a reference part, including a shape processing step and a bottom surfacegrinding step; machining a contour part, including an inner hole machining step and a notch machining step; a heat treatment part, including a tempering step and a bottom surface grinding step; a finish machining part, including a step of slowly threading an inner hole. The method is advantaged in that die precision can be improved, and deformation and scrapping are reduced.

Description

technical field [0001] The invention relates to mold processing, in particular to a powder metallurgy cross slip ring mold processing method. Background technique [0002] Oldham slip rings are parts of automotive compressors, usually manufactured by powder metallurgy. [0003] When making the Oldham slip ring, it is also necessary to use the Oldham slip ring mold, so that the Oldham slip ring can be punched. [0004] The cross slip ring mold is a tubular part with large inner diameter, large outer diameter, and thin wall thickness. The top surface of the cross slip ring mold also has multiple notches, thus meeting the processing needs of the cross slip ring. [0005] However, the precision of the mold for the Oldham slip ring is low, and it is also prone to cracking, which affects the production of the Oldham slip ring. Contents of the invention [0006] The object of the present invention is to at least solve one of the technical problems in the prior art, and provide ...
