Sand blasting method for aluminum alloy wheel hub

Abstract

The invention discloses a sand blasting method for an aluminum alloy wheel hub. The sand blasting method comprises the steps that the prototype of the aluminum alloy wheel hub passes through a first sand blasting section, a second sand blasting section and a third sand blasting section sequentially; the sand blasting of the first sand blasting section is conducted with quartz sand of the mesh number being 10-50; the sand blasting of the second sand blasting section is conducted with quartz sand of the mesh number being 50-100; and the sand blasting of the third sand blasting section is conducted with quartz sand of the mesh number being 100-300. According to the design, the prototype of the aluminum alloy wheel hub is made to pass through the first sand blasting section, the second sand blasting section and the third sand blasting section sequentially, so that the surface of the prototype of the aluminum alloy wheel hub is not just subjected to a one-step polishing process simply and accordingly the surface smoothness of the aluminum alloy wheel hub is greatly improved. Due to the fact that the gradient sand blasting is set sequentially, the surface of the aluminum alloy wheel hub can be polished effectively, and can be adjusted step by step according to the roughness of the surface, and the effect of the smoother surface is achieved.

Description

technical field [0001] The invention relates to a surface treatment process for an aluminum alloy wheel hub, in particular to a sandblasting method for an aluminum alloy wheel hub. Background technique [0002] As an important accessory in automobiles, aluminum alloy wheels play an extremely important role in automobiles. During the use of aluminum alloy wheels, the surface finish not only affects people's interest in purchasing them, but also affects the quality of products. Quality, the aluminum alloy wheels with too rough surface will often scratch the paint or scratch people if you are not careful during actual use. [0003] Therefore, it is an urgent need of the present invention to provide a sandblasting method for aluminum alloy wheels that can make the obtained aluminum alloy wheels have a high surface finish and will not scratch others or scratch the paint layer of the car surface in actual use. question.
