Abstract
The invention relates to an automatic spraying process of a compressor piston, which mainly comprises two procedures of spraying the piston and drying the piston after the spraying. The process is characterized in that the piston is pre-baked before being sprayed so as to remove the water adsorbed on the surface of the non-processed piston and increase the coating thickness of the first spraying.The automatic spraying process of the compressor piston uses the pre-baking method to heat and dry the piston before spraying and removes the water on the surface of the piston, thus effectively increasing the spraying thickness and reinforcing the adhesion of the coating. By circularly and repeatedly spraying the piston, the workpiece automatically rotates at a uniform speed when spraying the workpiece, thus ensuring the thickness requirement and uniformity requirement of the coating layer. Simultaneously the accurate pre-baking and drying temperature is determined, the best drying effect isachieved at the temperature, the energy resource used for drying is not wasted, thus achieving the object of reducing exhaust.
Description
Technical field
The present invention relates to a kind of spraying method, particularly a kind of automatic spraying process that is used for compressor piston.
Background technology
Compressor piston is because its bad working environment, need be piston outside the spraying abrasion-proof layer with the life-span of increase piston.The spraying of wearing layer is a very important production process, and the quality of wearing layer is directly connected to the service life of piston.The automanual spraying method of the general use of existing spraying method, the spraying that matches of artificial and machine, because manually-operated uncertainty, produce the spraying inhomogeneities, coating can't be attached on the piston uniformly, cause the thickness of piston coating uneven, also can appear at the coating layer thickness inequality of same piston sometimes, directly cause this piston to scrap.Simultaneously, when piston sprays,, cause the spray-on coating quality to descend because piston face is attached with certain moisture content.
Summary of the invention
The objective of the invention is provides a kind of coating even for the deficiency that solves above-mentioned technology, and the adhesion effect of coating is good, increase piston rub proofness and service life compressor piston automatic spraying process.
In order to achieve the above object, the automatic spraying process of the compressor piston that the present invention is designed, it mainly comprises piston is sprayed and spray the two procedures that dry piston the back, it is characterized in that before piston is sprayed piston being carried out prebake.Prebake can be removed the moisture content of undressed piston face absorption in advance before spraying, and increases the sprayed coating thickness of spraying first.
To uniformly spray effect and drying effect in order reaching, piston to be carried out prebake, remain piston when spraying and oven dry and carry out rotation.Simultaneously, when the coating required thickness of piston is big, behind piston---spraying---baking operation of having finished a prebake, again piston is sprayed---baking operation, promptly piston is carried out at least twice multilayer spraying repeatedly, till the specification requirement that reaches the piston sprayed coating.
In order to reach drying effect preferably, make coating that preferable quality be arranged, when piston is carried out prebake, its prebake temperature is between 40 ℃ to 100 ℃, is the best with 70 ℃ wherein, when piston is dried, its bake out temperature is 140 ℃ to 170 ℃, is good with 170 ℃ wherein.
The automatic spraying process of the resulting compressor piston of the present invention, the method for use prebake is just carried out heating, drying to piston before spraying, remove the moisture content of piston face, thereby effectively increases the thickness of spraying, the enhancing adhesive force of coatings.Repeatedly spray by piston cycle, and when the spraying workpiece, make workpiece at the uniform velocity rotation automatically, guarantee that coating layer thickness requires and uniformity requirement.Determined accurate prebake and bake out temperature simultaneously, can reach best drying effect under this temperature, being unlikely to again wastes the energy that oven dry is used, and reaches the purpose of energy-saving and emission-reduction.
Description of drawings
Fig. 1 is the embodiment of the invention 1 schematic flow sheet;
Fig. 2 is the embodiment of the invention 2 schematic flow sheets.
The specific embodiment
The invention will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1:
As shown in Figure 1, the automatic spraying process of the described compressor piston of present embodiment, it mainly is earlier piston to be carried out prebake, then piston is sprayed, and piston is dried at last again, finishes spraying coating process.In whole technical process, piston remains the state of rotation, guarantee spray-on coating drying be heated evenly.Described prebake temperature is controlled between 40 ℃ to 100 ℃ simultaneously, and bake out temperature is controlled between 140 ℃ to 170 ℃.Can carry out the adjusting of temperature according to the technological requirement and the characteristic of coating, in the hope of reaching best spraying effect.
Embodiment 2
As shown in Figure 2, the automatic spraying process of the compressor piston that present embodiment is described, behind piston---spraying---baking operation of having finished a prebake, again piston is sprayed---baking operation, form spraying---the circulation of baking operation, piston is carried out repeatedly the multilayer spraying, and till the specification requirement that reaches the piston sprayed coating, the passable thickness of piston coating that makes reaches more than 30 μ.Described prebake temperature is 70 ℃ simultaneously, and bake out temperature is 179 ℃.
