[0047] Working principle:

[0048] Fix the base frame 11 in the main structure 1 on the corresponding processing table, and support the base 12 at a certain height through the base frame 11 so that there is space for the gear rod on the first punching seat 14 to descend. Then, set the first punching seat 14, the second punching seat 31 and the die seat 33 that cooperate with each other according to the corresponding punching requirements;

[0049] During processing, the slice is placed on the die base 33 on the base 12, and at this time, the shielding frame 21 in the first shielding assembly 2 is forced by the spring 26 on the mounting frame 25, and the shielding frame 21 is perpendicular to the base 12 in the first flip opening 6, thereby blocking the rear side of the die base 33 to limit the punching workpiece of the slice; the same principle is used, and the second shielding assembly 4 is located on the rear side of the die base 33 on the second punching seat 31 to block and limit the workpiece, and similarly, the workpiece is placed on the die base 33 above the second punching seat 31;

[0051] Then, the lifting structure is controlled to move upward to punch another workpiece. Based on the same principle, the first gear rod 27 in the first shielding component 2 engages with the gear 24 in the second shielding component 4 to retract the shielding frame 21 in the second shielding component 4 into the second flip opening 7 to prevent obstruction. At the same time, after the gear 24 in the first shielding component 2 is disengaged from the second gear rod and the second punching seat 31 is away from the base 12, the shielding frame 21 in the first shielding component 2 is reset with the help of the spring 26 to block the material workpiece to be put in next time, thereby realizing the stamping process in both the lifting and lowering directions.

[0052] The equipment can set the required stamping die shape of the first stamping seat 14, the second stamping seat 31 and the die seat 33 according to actual needs, and set the length of the connecting rod 16 and the screw rod 18 according to needs to adjust the height of the stamping workpiece; and install the drive frame 15 in the first mounting groove 5 or the first socket 8 for fixed assembly.
