A clamping plate 610 is fixedly installed at one end of the extension rod 69;

[0030] The specific implementation method is as follows: When the punching plate 3 moves downward to punch the workpiece, the punching plate 3 drives the long rod 4 to move downward. The long rod 4 drives the lower pressing plate 61 to move. While the lower pressing plate 61 moves, it drives the toothed plate 62 to move. The gear 63 is meshed with the toothed plate 62. When the toothed plate 62 moves, it drives the gear 63 to rotate. The gear 63 drives the threaded rod 65 to rotate through the transmission rod 64. The outer wall of the threaded rod 65 is threadedly connected with the internally threaded ring 67. When the threaded rod 65 rotates, it drives the internally threaded ring 67 to move on its outer wall. While the internally threaded ring 67 moves, it drives the extension rod 69 to move through the connecting rod 68. The extension rod 69 will drive the clamping plate 610 to move, so as to fix the workpiece placed in the placement groove 2.

[0031] The anti-warping edge component 7 includes a fixing plate 71. One side of the fixing plate 71 is fixedly installed on the side wall of the clamping plate 610.

An arc plate 75 is fixedly installed on one side of the extrusion plate 74. A second spring 73 is sleeved on the outer wall of the telescopic rod 72;

[0032] The specific implementation method is as follows: When the clamping plate 610 displaces and clamps the side wall of the workpiece, the clamping plate 610 squeezes the arc plate 75, causing it to displace upward. The arc plate 75 drives the extrusion plate 74 to displace a short distance. When the workpiece displaces to the bottom of the extrusion plate 74, the extrusion plate 74 will be squeezed, driving one end of the second spring 73 to be squeezed, causing the second spring 73 to be in a compressed state. Then it will generate a downward elastic force, and this elastic force presses down on the edge of the workpiece through the extrusion plate 74.

[0033] Working principle: When the stamping plate 3 moves downward to stamp the workpiece, the stamping plate 3 drives the long rod 4 to move downward. The long rod 4 drives the lower pressing plate 61 to displace. While the lower pressing plate 61 displaces, it drives the toothed plate 62 to displace. The gear 63 is meshed with the toothed plate 62. When the toothed plate 62 displaces, it drives the gear 63 to rotate. The gear 63 drives the threaded rod 65 to rotate through the transmission rod 64. The outer wall of the threaded rod 65 is threadedly connected with the internal thread ring 67. When the threaded rod 65 rotates, it drives the internal thread ring 67 to displace on its outer wall. While the internal thread ring 67 displaces, it drives the extension rod 69 to displace through the connecting rod 68. The extension rod 69 drives the clamping plate 610 to displace, fixing the workpiece placed in the placement groove 2. When the clamping plate 610 displaces and clamps the side wall of the workpiece, the clamping plate 610 squeezes the arc plate 75, causing it to displace upward. The arc plate 75 drives the extrusion plate 74 to displace a short distance. When the workpiece displaces to the bottom of the extrusion plate 74, the extrusion plate 74 will be squeezed, driving one end of the second spring 73 to be squeezed, causing the second spring 73 to be in a compressed state. Then it will generate a downward elastic force, and this elastic force presses down on the edge of the workpiece through the extrusion plate 74.
