Problems solved by technology

Due to the defects of large environmental pollution, complex recycling process, high energy consumption and low efficiency of heat treatment in the electroplating copper and stripping processes in the prior art, in addition, the copper electroplating and centerless grinding processes have problems of low production efficiency and poor quality stability. Defects, among which, poor quality stability is manifested in: the electroplated copper layer is prone to fall off during subsequent use and processing, and it is difficult to control the stability of centerless grinding accuracy
When the current product style is interference fit with the compressor body, there are still defects such as large fitting pressure, poor assembly stability, poor steel plasticity, small variability, and insufficient sealing, which may easily cause deformation of the compressor pump body and affect the performance of compression refrigeration.

Abstract

The invention relates to the technical field of connecting pipes of compressors, in particular to a production technology for a connecting pipe of a compressor. The production technology for the connecting pipe of the compressor includes the steps that firstly, material selecting is conducted; and secondly, continuous multistage punching stretching forming or pipe machining technology forming is adopted, wherein firstly continuous multistage punching stretching forming is adopted includes the first step of blanking, the second step of multistage stretching, the third step of trimming, the fourth step of punching and the fifth step of shaping, and secondly, pipe machining technology forming is adopted; thirdly, polishing cleaning is conducted; and fourthly, drying is conducted. The production technology for the connecting pipe of the compressor has the beneficial effects of environment friendliness and energy conservation, due to the fact that the end portion of a diffusionless pipe end portion is covered with a red copper plate layer, assembling stability and sealing performance of the connecting pipe of the compressor can be improved, deformation of pump body parts can be reduced, the production efficiency can be greatly improved, and the quality reject ratio is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of compressor connecting pipes, in particular to a production process for compressor connecting pipes. Background technique [0002] At present, the connecting pipes for air-conditioning compressors generally use 10# steel pipes or cold-rolled low-carbon steel plates. Angle→centerless grinding→polishing cleaning→drying→shipping inspection) or stamping and stretching process (incoming material inspection→stamping and stretching forming→electroplating copper→deplating→polishing cleaning→drying→shipping inspection) production. Copper electroplating is to facilitate the brazing of the expanded tube side and related components. The centerless grinding / deplating process is to remove the electroplated copper layer attached to the non-expanded tube side, which is convenient for interference fit with the compressor body and ensures that no copper layer falls off. Due to the defects of large environmental pollution, ...
