Description

Technical Field

[0001] The invention relates to the technical field of casting processing, and in particular to a casting surface refinement treatment process. Background Art

[0002] Castings are made by pouring liquid metal into a mold cavity that is compatible with the shape and size of the part and waiting for it to cool and solidify to obtain a blank or part.

[0003] Common castings include motor housings. In order to prevent the motor housing from rusting after long-term use, a protective layer is usually sprayed on the outer surface of the motor housing. However, the surface of the newly cast motor housing is relatively rough, and the direct spraying of the protective layer is not effective. Therefore, the motor housing needs to be finely processed first. There are usually a large number of heat sinks on the motor housing, and the gaps between these heat sinks are not easy to be finely processed. At present, the existing processing methods are mostly to lift the motor housing and polish its surface by sandblasting. However, in this method, during the process of spraying polishing sand, the polishing sand will constantly hit the motor housing, and the cast iron motor housing is prone to hidden cracks inside after being hit. This situation reduces the strength of the motor housing. Secondly, the existing fine processing method needs to collect the sprayed polishing sand again after use for reuse. This situation reduces the efficiency of the fine processing of the motor housing and increases the cost of the fine processing of the motor housing. Summary of the invention
