Abstract
The invention discloses a kind of coating process, especially a kind of method of the surface coating to automobile air conditioner compressor piston cylindrical shell; The object of the present invention is to provide and a kind ofly reduce cost, make piston of automobile drum surface coating evenly and the method for the high surface coating to automobile air conditioner compressor piston cylindrical shell of utilization efficiency of coatings; The first step: by clean for the process of automobile air conditioner compressor piston drum surface; Second step: serigraphy process is carried out to automobile air conditioner compressor piston drum surface; 3rd step: sintering processes; 4th step: discharging; The method of the surface coating to automobile air conditioner compressor piston cylindrical shell of gained of the present invention, even by the teflon coatings thickness of automobile air conditioner compressor piston drum surface after screen printing technique processing, thus reduce cost, also improve the utilization rate of coating.
Description
Technical field
The present invention relates to a kind of coating process, especially a kind of method of the surface coating to automobile air conditioner compressor piston cylindrical shell.
Background technology
At present, enterprise can adopt the mode of spraying at the surface spraying last layer teflon coatings of piston of automobile cylindrical shell in the process of production automobile air conditioner compressor piston, its processing technology is: first by clean for the surface treatment of automobile air conditioner compressor piston cylindrical shell, then on the surface of automobile air conditioner compressor piston cylindrical shell with spray gun spraying one deck teflon coatings, the process of sintering official business is carried out again after spraying, finally grinding process is carried out to the coating of automobile air conditioner compressor piston drum surface spraying, thus make the coating layer thickness of automobile air conditioner compressor piston drum surface consistent.
But there is some shortcoming following in this machining process: first, the utilization rate of Teflon coating is low, it is 100% that sprayed coating content is robbed in spray, the amount that can really use on automobile air conditioner compressor piston cylindrical shell but only has 20%, and the coating that the mode of this spraying also exists ejection can drop to the ground downwards in a large number, thus the waste causing Teflon coating a large amount of, make cost higher; The second, owing to being carry out spray treatment by the mode of spray gun spraying, making the teflon coatings thickness spraying rear automobile air conditioner compressor piston drum surface wayward, make the teflon coatings of automobile air conditioner compressor piston drum surface in uneven thickness.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and reduce cost, make piston of automobile drum surface coating evenly and the method for the high surface coating to automobile air conditioner compressor piston cylindrical shell of utilization efficiency of coatings.
In order to achieve the above object, the method for the surface coating to automobile air conditioner compressor piston cylindrical shell designed by the present invention, step is as follows:
The first step: by clean for the process of automobile air conditioner compressor piston drum surface;
Second step: serigraphy process is carried out to automobile air conditioner compressor piston drum surface, screen printing forme technology is utilized to print, on screen printing forme one end, Teflon coating is poured into during printing, certain pressure is applied with scraping the Teflon coating position of scraper plate on screen printing forme, move towards the screen printing forme other end simultaneously, automobile air conditioner compressor piston cylindrical shell starts to rotate, and Teflon coating is expressed to the surface of automobile air conditioner compressor piston cylindrical shell in movement from mesh by scraper plate;
3rd step: sintering processes, is placed into the automobile air conditioner compressor piston cylindrical shell after serigraphy process in sintering machine and carries out sintering processes;
4th step: discharging.
According to the above, the method of the surface coating to automobile air conditioner compressor piston cylindrical shell of gained of the present invention, the mode of serigraphy is changed over by original spraying method, as long as and adjustment scrapes the thickness of scraper plate with regard to control teflon coatings that can be fabulous when serigraphy, make by the teflon coatings thickness of automobile air conditioner compressor piston drum surface after screen printing technique processing even, thus reduce cost, also improve the utilization rate of coating.
Detailed description of the invention
The method of the surface coating to automobile air conditioner compressor piston cylindrical shell that the present embodiment describes, step is as follows:
The first step: by clean for the process of automobile air conditioner compressor piston drum surface;
Second step: serigraphy process is carried out to automobile air conditioner compressor piston drum surface, screen printing forme technology is utilized to print, on screen printing forme one end, Teflon coating is poured into during printing, certain pressure is applied with scraping the Teflon coating position of scraper plate on screen printing forme, move towards the screen printing forme other end simultaneously, automobile air conditioner compressor piston cylindrical shell starts to rotate, and Teflon coating is expressed to the surface of automobile air conditioner compressor piston cylindrical shell in movement from mesh by scraper plate;
3rd step: sintering processes, is placed into the automobile air conditioner compressor piston cylindrical shell after serigraphy process in sintering machine and carries out sintering processes;
4th step: discharging.
