[0023] Specifically, a motor 18 is installed at the rear of the base 4 , and the rotation of the motor 18 drives the connected rotating frame 14 to rotate, and the output end of the motor 18 is fixedly connected to the rotating frame 14 .

[0024] Specifically, an upper die 10 is installed at the bottom of the punching frame 3 , and the downward movement of the punching frame 3 drives the upper die 10 to move downward to punch the workpiece below. The upper die 10 is located above the die groove 7 .

[0025] Specifically, the mold base 5 is installed on the surface of the machine base 4 , the mold base 5 is fixed on the surface of the machine base 4 , and the mold base 5 is slidably connected with a connecting plate 15 , and the connecting plate 15 can slide up and down along the mold base 5 .

[0026] Specifically, the spring 12 is located between the stamping frame 3 and the pressing plate 9 , and the pressing plate 9 moves downward to compress the spring 12 . The pressing plate 9 is located on both sides of the upper die 10 .
