Description

Technical Field

[0001] The utility model relates to the technical field of burr removal devices, in particular to a burr removal device for sheet metal edges. Background Art

[0002] Sheet metal processing is a comprehensive cold processing technology for thin metal plates, including shearing, punching, cutting, compounding, folding, riveting, splicing, forming, etc. It has been widely used in the fields of electronics, communications, automotive industry, medical equipment, etc. After punching, shearing and cutting of sheet metal plates, burrs are prone to appear on the edges, which affects the accuracy of subsequent processing and is also prone to cause cuts.

[0003] In the prior art, since the thickness of the metal sheet is usually less than 6 mm, when the edge is ground and deburred, the edge of the metal sheet is easily deformed during the grinding process, resulting in the overall flatness of the edge after grinding being difficult to control. In addition, during grinding, since the edge is thin, the burrs are easily squeezed to the edge of the edge, resulting in the burrs on the upper and lower edges of the metal edge cannot be effectively removed. Utility Model Content
