[0041] The upper die assembly 102 comprises a stamping head 115 matched with the stamping hole 108, and the stamping head 115 is matched with the stamping hole 108 for stamping forming of the workpiece;

[0042] As shown in Figure 1 and 4 , the utility model stamping die in the use process, the blank is placed on the bearing plate 104, through the stamping head 115 and the stamping hole 108 are matched with the stamping, so that the circular workpiece stamping forming and finally fall into the bearing block 114, the circular workpiece is placed on the bearing block 114 The periphery is abutted with the inner wall of the annular polishing piece 111, the power piece 113 drives the transmission piece 112, and the transmission piece 112 drives the annular polishing piece 111 to reciprocate at high speed, so that the periphery of the circular workpiece is polished smooth, thereby facilitating subsequent high-quality processing;

[0063] The state of the elastic piece 129 on the second guide column 127 makes the elastic abutting plate 128 contact the workpiece and apply a progressive pressure before the stamping head 115, effectively absorbs the rigid impact in the stamping moment, and forms stable limiting for the blank, avoiding the displacement of the blank affecting the stamping precision in the stamping process;

[0064] The outer wall of the elastic abutting plate 128 is slidably sleeved with the vertical constraint of the first guide column 124, so as to ensure the trajectory accuracy of the stamping head 115 in high-speed reciprocating motion.
