The upper pressure plate 23 has an L-shaped storage groove 43 at the position corresponding to the two L-shaped limiting blocks 19 to receive the L-shaped limiting blocks 19. The power output of the lifting drive motor 18 causes the L-shaped limiting blocks 19 to rise or fall.

[0032] The operation steps of this embodiment are as follows:

[0033] 1. Place the material 47 to be punched on the lower module 10. The L-shaped limiting blocks 19 of the limiting structure on both sides rise to a predetermined height to limit the opposite sides of the material 47. The first electromagnetic chuck 11 adsorbs and fixes the material 47.

[0034] 2. The punching drive motor 25 causes the upper pressure plate 23 to move the punching blade 34 downward to form and punch the material 47;

[0035] 3. The punching drive motor 26 causes the punching column 42 to move down to complete the punching action and then resets. At the same time, the upper pressure plate 23 also resets.

[0036] 4. The self-unloading structure 21 picks up the punched finished product 44, flips it at a predetermined angle, and moves it to the next process. It will be connected to the conveyor belt. The self-unloading structure 21 directly places the finished product 44 on the conveyor belt. Then, the second rotary drive motor 15 drives the U-shaped tipping rod 14 to perform a flipping action, flipping up the remaining edge scrap 46 and pushing it out to the waste collection box 13. At the same time, the electric push-pull rod 27 outputs power to cause the L-shaped push rod 28 to push the waste 45 located in the buffer trough 17 into the inclined discharge channel 36.

[0037] 5. Repeat step 1.

[0038] This implementation method can realize the functions of punching, punching, automatic unloading, automatic waste removal, and anti-blocking of the buffer groove for punching. It has a high degree of automation and improves processing efficiency.
