A surface treatment process for aluminum-magnesium alloy precision die-casting parts

Abstract

The invention relates to a surface treatment process for aluminum-magnesium alloy precision die-casting parts, which uses a surface treatment device for aluminum-magnesium alloy precision die-casting parts. , spray head, conveying mechanism and cleaning mechanism, the present invention can solve the problem that during the surface treatment process of aluminum-magnesium alloy precision die-casting parts, due to the complex shape of the outer surface of the die-casting part, it is necessary to replace cleaning tools with different diameters according to different grinding and cleaning areas. A large number of repetitive operations increase the labor intensity of the workers, and it is difficult to wash the outer surface of the die casting during the process of conveying it, and it is also difficult to make the die casting vibrate and accelerate Problems such as burrs and residue drop effects.

Description

technical field [0001] The invention relates to the field of die-casting preparation, in particular to a surface treatment process for aluminum-magnesium alloy precision die-castings. Background technique [0002] Die-casting is a kind of pressure-casting part. It uses a pressure-casting mechanical die-casting machine equipped with a casting mold to pour liquid copper, zinc, aluminum or aluminum alloy into the feed port of the die-casting machine, and passes through the die-casting machine. Die casting, casting copper, zinc, aluminum parts or aluminum alloy parts of the shape and size limited by the mold, such parts are usually called die castings. Because copper, zinc, aluminum and aluminum alloys have good fluidity and plasticity, and the casting process is cast in a pressure die-casting machine, aluminum die-castings can be made into various more complex shapes, and can also be made into more complex shapes. High precision and smoothness, thereby greatly reducing the mac...

Problems solved by technology

[0004] 1) Due to the complex shape of the outer surface of the die-casting parts, the grinding operation is often done manually. Usually, the number of die-casting parts produced in the same batch is large, and cleaning tools of different diameters need to be replaced according to different grinding and cleaning areas. Repeated operations increase the labor intensity of the workers, and the sharp edges of the die-casting parts may cause injury to the workers during the grinding process
