Description
Technical Field
[0001] This utility model relates to the field of punching equipment technology, and in particular to a device for punching holes on both sides of a workpiece. Background Technology
[0002] In the attached document Figure 1 When punching mounting holes on both sides of the workpiece, the workpiece first needs to be fixed with a fixture. Then, while the abutment block abuts against the inner wall of the workpiece, the side wall of the workpiece is impacted by the punching rod to punch the mounting holes. Traditionally, punching is done manually, but the punching efficiency is low and the punching accuracy cannot be guaranteed. In order to improve the punching efficiency, automated equipment is now used to assist punching. However, in order for the abutment block to be able to extend smoothly into the workpiece without interfering with it, the volume of the abutment block is usually smaller than the gap of the workpiece. This causes the abutment block to not be able to abut against the inner wall of the workpiece, which may cause the side wall of the workpiece to deform during the punching process, thus affecting the punching accuracy. Therefore, improvement is necessary. Utility Model Content
