Abstract

The invention belongs to the technical field of machining parts and in particular to a machining method for a stop ring. The machining method for the stop ring takes a GCr15 bearing-steel steel pipe as a raw material and the inner and outer diameters of the steel pipe are sizes of the inner and outer diameters of a stop ring blank; and then the steel pipe is cut to obtain the stop ring blank. According to the machining method for the stop ring, provided by the invention, the qualitative transition is realized by abandoning sheet material machining and replacing the sheet material machining with pipe machining, so that the utilization rate of the material is improved and material stress generated by rolling the material for a plurality of times is reduced; a cutting method is used for replacing punching so that punching machining stress of the blank is reduced and a foundation of solving a planeness problem is laid for subsequent machining; a heat treatment method is modified and the material stress, machining stress and heat treatment deformation are controlled to be minimum; and in conclusion, the problems of uncontrollable planeness, poor parallelism, poor thickness and plane roughness in an old method are solved through the machining method provided by the invention and the yield and market credibility of a product are improved.

Description

technical field

[0001] The invention belongs to the technical field of mechanical processing parts, and in particular relates to a processing method of a stop ring. Background technique

[0002] The stop ring is a commonly used part in mechanical parts. As an important part of the car air-conditioning compressor, its quality directly affects the noise, mechanical performance, and even life of the whole machine.

[0003] The processing method of the stop ring generally includes the following steps:

[0004] 1) Forming the inner and outer diameter of the stop ring; 2) Stamping and leveling the plane of the stop ring; 3) Soft grinding processing of both front and back planes; 3) Heat treatment; 4) Centerless grinding of the outer diameter of the stop ring; 5) Hard grinding of the stop ring 6) The inner diameter of the stop ring is ground on the inner die; 7) The inner diameter and outer diameter of both sides are chamfered; 8) The stability treatment eliminates the processing ...
