Description

Technical Field

[0001] This utility model relates to the technical field of workpiece processing, specifically a device for quickly removing sharp edges and burrs from workpiece punch cuts. Background Technology

[0002] After the workpiece is punched, if the clearance between the punch and die is not set properly, the upper and lower cracks will not coincide, resulting in burrs when the material is separated, which in turn form sharp edges that are easy to prick. Therefore, after the workpiece is punched, it is necessary to remove the sharp edges and burrs on the workpiece. Existing devices for removing sharp edges and burrs from workpieces are inconvenient to adjust the workpiece angle during processing, making it difficult to remove sharp edges and burrs from different positions on the workpiece. Furthermore, traditional devices for removing sharp edges and burrs from workpieces generate dust and debris during the removal process, resulting in poor performance. Therefore, we propose a device for quickly removing sharp edges and burrs from workpiece punch cuts to solve the problems mentioned above. Utility Model Content
