A grinding mechanism 9 is installed on the lower surface of the lower pressing plate 3 just below the stamping through-hole 7. The grinding mechanism 9 includes: a mounting plate 901, Grinding motor 904, one end of the grinding motor 904 is located above the mounting pad 901 and is equipped with a grinding head, the interior of the mounting pad 901 is located on the lower surface of the lower pressure plate 3 and is equipped with a limiting rod 902, the mounting pad 901 is movably connected to the limiting rod 902, the limiting rod 902 is fixedly connected to the lower pressure plate 3, and a spring 903 is sleeved on the outside of the limiting rod 902 below the mounting pad 901, and the mounting pad 901 is fixedly connected to the limiting rod 902 through the spring 903.

[0024] like Figure 2-3 As shown, in this embodiment, the lower surface of the impeller plate limit frame 8 is located on the side close to the stamping perforation 7 and is provided with an impeller plate slot 801. The lower surface of the impeller plate limit frame 8 is located inside the movable slide 6 and is installed with a guide slider 802. The impeller plate limit frame 8 is slidingly connected to the movable slide 6 through the guide slider 802. The upper surface of the impeller plate limit frame 8 is located on the side away from the impeller plate slot 801 and is installed with a positioning screw 803. The positioning screw 803 is engaged and movably connected with the impeller plate limit frame 8. A guide rod 4 is connected between the upper pressure plate 2 and the lower pressure plate 3. The upper pressure plate 2 is movably connected to the guide rod 4.
