[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as car body), etc. Its notable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts. After the sheet metal is produced, its surface usually has burrs, so the sheet metal needs to be deburred.

[0003] At present, the conventional sheet metal deburring device mainly uses a grinding belt to grind and deburr the surface of the sheet metal. However, only the top surface of the sheet metal can be deburred each time. Therefore, after the burrs on the upper surface of the sheet metal are removed, the sheet metal needs to be turned over and the other side of the sheet metal needs to be grinded and deburred. Therefore, the deburring efficiency of the sheet metal is low. Utility Model Content
