Stripping device and stripping method for preparing copper-plated tube for air-conditioning compressor

Abstract

The invention relates to a deplating device for preparing copper-plated pipes for air-conditioning compressors. The deplating pool is connected to the deplating chemical solution circulation system, and the deplating chemical solution will be between the deplating pool and the deplating chemical solution circulation system during the deplating process. To achieve circular supply and recovery, the base is height-adjustable and installed in the deplating pool. Multiple semi-finished tubes are placed vertically on the base, and the section that needs to be deplated faces downward; each semi-finished tube needs to be deplated for a section. The deplating height is α1; the deplating chemical liquid level height in the deplating pool is α2; the distance between the plane contacting the base and the semi-finished pipe body and the bottom surface of the deplating pool is α3; α1=α2 α3; the present invention also The invention includes a method for deplating copper-plated pipes for air-conditioning compressors by using a deplating device, including chemical deplating, and partially deplating semi-finished pipe bodies. The invention adopts chip-free processing to complete partial deplating, does not produce iron filings and burrs, reduces processing steps, effectively reduces production costs, and prolongs service life.

Description

technical field [0001] The invention relates to the processing field of copper-plated pipes for air-conditioning compressors, in particular to a deplating device and a deplating method for preparing copper-plated pipes for air-conditioning compressors. Background technique [0002] At present, the production process of copper-plated tubes for air-conditioning compressors is generally to perform full electroplating on the formed tube body, and then turn or grind one section of the copper-plated tube to remove the copper-plated layer on the surface, and the iron The surface of the pipe body is exposed again, so as to achieve the purpose of welding one end of the pipe body with the iron material or an interference tight fit seal with the cylinder, and welding the inner end of the compressor with the copper material, as disclosed in Chinese invention patent ZL201110389070.7. Although the structure can achieve the above purpose, it also has the following defects: 1) The step of t...

[0002] At present, the production process of copper-plated tubes for air-conditioning compressors is generally to perform full electroplating on the formed tube body, and then turn or grind one section of the copper-plated tube to remove the copper-plated layer on the surface, and the iron The surface of the pipe body is exposed again, so as to achieve the purpose of welding one end of the pipe body with the iron material or an interference tight fit seal with the cylinder, and welding the inner end of the compressor with the copper material, as disclosed in Chinese invention patent ZL201110389070.7. Although the structure can achieve the above purpose, it also has the following defects: 1) The step of turning the copper layer, otherwise the tube body will be covered with tiny iron powder, iron filings, burrs and other impurities, which will cause great trouble to the later cleaning , if the cleaning is not clean, the pipe body with residual impurities is directly installed on the compressor, which will cause the compressor to stall and seriously affect the work of the compressor; When the copper layer is cut off, the iron part is often cut off a little, resulting in a smaller thickness of the pipe body, a decrease in strength, and a decrease in service life; The manufacturing cost is high, and it is easy to produce poor processing, resulting in high scrap rate, and the surface of the tube body is damaged by multiple clamping of mechanical processing, which affects the assembly accuracy
