Problems solved by technology
There are mainly two ways to achieve it. One is to transfer the LOGO pattern to the wheel hub by pad printing after spraying a color. This method uses the principle of gravure printing, and the pad printing equipment transfers the ink to the hub surface through the rubber head. Print out the LOGO pattern; this process requires precise confirmation of ink adjustments, pattern lines, etc., which will waste a lot of manpower, and waste ink generated by pad printing also needs to be cleaned up, wasting costs; the second is to spray a After coloring, use self-adhesive labeling to display the LOGO on the wheel hub
However, there are still many defects and risks in these methods at present. The pad printing scheme will cause the color difference of the pattern, the lines are not clear and incomplete, and there may even be a risk that the LOGO pattern will fall off in the later stage.

Abstract
The invention provides a laser spraying process for a precise pattern of a wheel hub. According to the laser spraying process for the precise pattern of the wheel hub, the three-dimensional numericalquantity in the laser marking process is strictly controlled, and the pretreatment, powder primer spraying, color paint spraying and powder permeabilizing processes are performed before and after thelaser treatment of the pattern, so that the laser marking of the pattern can be performed on the basis that a certain amount of color paint is sprayed onto the wheel hub in the laser process; after the laser marking of the pattern is finished, the wheel hub is subjected to washing and powder permeabilizing again; and after the wheel hub is subjected to powder permeabilizing treatment again, not only can the clearness of the pattern be guaranteed, but also the high precision of the pattern can be achieved.
Description
technical field [0001] The invention relates to the technical field of laser spraying, in particular to a precise pattern laser spraying process for wheel hubs. Background technique [0002] At present, the aluminum alloy wheels on the market are all finished by machining after casting or forging, and the surface decoration is finished by painting and spraying. With the changes in aesthetics and individual needs, there are more and more wheel shapes, and the requirements for surface decoration are also getting higher and higher. Many wheel hubs have more personalized LOGO patterns. There are mainly two ways to achieve it. One is to transfer the LOGO pattern to the wheel hub by pad printing after spraying a color. This method uses the principle of gravure printing, and the pad printing equipment transfers the ink to the hub surface through the rubber head. Print out the LOGO pattern; this process requires precise confirmation of ink adjustments, pattern lines, etc., which wi...
