Abstract
The invention discloses a coating method, and particularly provides a method for carrying out coating on the surface of an automobile air conditioning compressor piston cylinder. The method is capable of reducing the cost, enabling the coating on the surface of an automobile piston cylinder to be uniform and having a high coating utilization rate. The method comprises the steps of a first step, cleanly treating the surface of the automobile air conditioning compressor piston cylinder; a second step, carrying out silk screen printing treatment on the surface of the automobile air conditioning compressor piston cylinder; a third step, carrying out sintering treatment; a fourth step, discharging. According to the method for carrying out the coating on the surface of the automobile air conditioning compressor piston cylinder, disclosed by the invention, the thickness of a Teflon coating layer on the surface of the automobile air conditioning compressor piston cylinder after being processed through a silk screen printing technology is uniform, thus the cost is reduced, and the coating utilization rate is also increased.
Description
Technical field
The present invention relates to a kind of coating process, especially a kind of method to the surface coating of automobile air conditioner compressor piston barrel.
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 producing automobile air conditioner compressor piston, its processing technology is: first that the surface treatment of automobile air conditioner compressor piston barrel is clean, then at the surface of automobile air conditioner compressor piston barrel spray gun spraying one deck teflon coatings, after spraying, carrying out sintering processes on business again, finally the coating of automobile air conditioner compressor piston barrel surface spraying is carried out to grinding process, thereby make the coating layer thickness on automobile air conditioner compressor piston barrel surface consistent.
But in this machining process, there is following some shortcoming: 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 barrel but only has 20%, and the mode of this spraying also exists the coating of ejection to drop to the ground in a large number downwards, thereby cause a large amount of waste of Teflon coating, make cost higher; The second, owing to being that mode by spray gun spraying is carried out spray treatment, the teflon coatings thickness that makes to spray rear automobile air conditioner compressor piston barrel surface is wayward, makes the teflon coatings on automobile air conditioner compressor piston barrel 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 the method to the surface coating of automobile air conditioner compressor piston barrel that piston of automobile drum surface coating is even and utilization efficiency of coatings is high.
In order to achieve the above object, the method to the surface coating of automobile air conditioner compressor piston barrel that the present invention is designed, step is as follows:
The first step: the surface treatment of automobile air conditioner compressor piston barrel is clean;
Second step: serigraphy processing is carried out in automobile air conditioner compressor piston barrel surface, utilize screen printing forme mesh not the basic principle of strike through print, during printing, on screen printing forme one end, pour Teflon coating into, with scraping the Teflon coating position of scraper plate on screen printing forme, apply certain pressure, towards the screen printing forme other end, move simultaneously, automobile air conditioner compressor piston barrel starts rotation, and Teflon coating is expressed to the surface of automobile air conditioner compressor piston barrel in movement from mesh by scraper plate;
The 3rd step: sintering processes, is placed into the automobile air conditioner compressor piston barrel after serigraphy is processed to carry out sintering processes in sintering machine;
The 4th step: discharging.
According to the above, the method to the surface coating of automobile air conditioner compressor piston barrel of gained of the present invention, by original spraying method, changed over the mode of serigraphy, and as long as regulate, scrape scraper plate with regard to the thickness of the fabulous control teflon coatings of energy when serigraphy, make the teflon coatings even thickness on automobile air conditioner compressor piston barrel surface after processing by screen printing technique, thereby reduced cost, also improved the utilization rate of coating.
The specific embodiment
The method to the surface coating of automobile air conditioner compressor piston barrel that the present embodiment is described, step is as follows:
The first step: the surface treatment of automobile air conditioner compressor piston barrel is clean;
Second step: serigraphy processing is carried out in automobile air conditioner compressor piston barrel surface, utilize screen printing forme mesh not the basic principle of strike through print, during printing, on screen printing forme one end, pour Teflon coating into, with scraping the Teflon coating position of scraper plate on screen printing forme, apply certain pressure, towards the screen printing forme other end, move simultaneously, automobile air conditioner compressor piston barrel starts rotation, and Teflon coating is expressed to the surface of automobile air conditioner compressor piston barrel in movement from mesh by scraper plate;
The 3rd step: sintering processes, is placed into the automobile air conditioner compressor piston barrel after serigraphy is processed to carry out sintering processes in sintering machine;
The 4th step: discharging.
