Abstract

The invention belongs to the technical field of preparation methods for double-metal composite sliding plates of automobile air-conditioning compressors and moulds, and discloses a preparation method for a double-metal composite sliding plate of an automobile air-conditioning compressor, a powder laying and sintering mould and a rotary forging mould. The preparation method and the moulds are characterized in that the surface of a matrix is copperized or sprayed with an adhesive layer, copper alloy powder is laid on the two surfaces of the matrix through the special powder laying and sintering mould, and one-time two-surface sintering is achieved; then a rotary forging and compacting method is adopted, tempering treatment is lastly performed, therefore, the binding force between a copper alloy layer and matrix metal is further improved, and work hardening is eliminated. Through detection, according to the double-metal composite sliding plate, produced by adopting the method, of the automobile air-conditioning compressor, tin bronze is adopted to serve as the copper alloy powder, and the shearing strength between the tin bronze and the matrix is above 150 Mpa and is much larger than that of other composite methods.

Description

technical field [0001] The invention belongs to the technical field of a method for preparing a sliding plate of an automobile air-conditioning compressor and molds, and in particular relates to a method for preparing a bimetallic composite sliding plate of an automobile air-conditioning compressor, a special powder-spreading sintering mold and a swing rolling mold. Background technique [0002] The swash plate of the air conditioner compressor mainly acts as a high-speed sliding mechanism. Aiming at the problem of seizure failure that is easy to occur in the use of swash plate air-conditioning compressors, people choose to improve the lubricity of the swash plate by improving the surface coating and matrix material of the swash plate. Before the improvement, the base material of the swash plate was 45# steel, but when the surface coating was worn, the sliding shoe would slide directly on the 45 steel base material at high speed. Due to the material characteristics of 45 # s...
