[0031] In specific implementation, when the rotating cylinder 5 drives the fixed ring 501 to rotate, and then drives the multiple movable sliders 504 to rotate together, the grinding piece at the lower part of the movable slider 504 performs annular grinding on the burr. In the actual stamping process, the aperture requirements are also different. After the punch head 201 is replaced, for different apertures, the operator can rotate the driving screw 503, and the driving screw 503 drives the movable slider 504 to move outside the sliding plate 502, so as to adjust the grinding position according to different apertures, and the application range is wider. The grinding piece in this embodiment can be a grinding block, and the bottom of the grinding block is at the same level as the bottom of the supporting contact column 403, ensuring that the burrs on the workpiece can be processed.

[0032] In this embodiment: Figure 8 and Fig. 9 As shown, the grinding piece includes: Two auxiliary support plates 5041 are fixedly connected to the bottom of the movable slider 504, a first transmission wheel 5042 and a second transmission wheel 5043 are arranged between the two auxiliary support plates 5041, and the second transmission wheel 5043 is rotatably connected to the auxiliary support plate 5041, and a grinding belt 5044 for grinding burrs is sleeved between the first transmission wheel 5042 and the second transmission wheel 5043; The transmission member is used to drive the first transmission wheel 5042 to transmit, thereby driving the grinding belt 5044 to grind the burrs.
