[0031] The punching device 3 is driven by the hydraulic cylinder 2 to move and punch the iron plate inside the iron plate storage box 1. The punching device 3 moves back and forth once to punch the iron plate inside the iron plate storage box 1 twice, which improves the punching rate. After the punching device 3 punches the iron plate, the punching device 3 adjusts the position of the iron plate through the position limiting device 5 to avoid safety hazards when the iron plate is moved manually.

[0032] Among them, Figure 1-9 As shown, the iron plate storage box 1 includes a storage box body 1-1, a storage cavity 1-2 and a through hole 1-3. The storage box body 1-1 is provided with a storage cavity 1-2 for storing iron plates. The through hole 1-3 runs through the storage box body 1-1. The driving punching device 3 punches the iron plate inside the storage cavity 1-2 through the through hole 1-3. The storage box body 1-1 is provided with a collecting box 4 below the through hole 1-3. The position limiting device 5 is arranged inside the storage box body 1-1.

Two releasing devices 5-2 are arranged inside the storage box body 1-1. The releasing device 5-2 releases the restriction on the position of the iron plate by the limiting device 5-1. The movable mounting frame 3-1 drives the releasing device 5-2 to release the restriction on the limiting device 5-1 through the first connecting device 5-3 or the second connecting device 5-4.

[0036] When the mounting frame 3-1 is stamping, the mounting frame 3-1 drives two stamping columns 3-2, the first connecting device 5-3 and the second connecting device 5-4. When one of the stamping columns 3-2 completes stamping the iron plate, it resets and moves. During the moving over-punching, one of the first connecting device 5-3 or the second connecting device 5-4 drives one of the releasing devices 5-2 to move. The moving releasing device 5-2 drives the limiting device 5-1 to move and releases the restriction on the iron plate. Then the stamping column 3-2 detaches from the stamping hole on the iron plate. While the iron plate falls, the limiting device 5-1 resets into the inside of the stamping hole just after stamping to limit the position of the iron plate. Then the other stamping column 3-2 stamps the iron plate. After stamping, the second connecting device 5-4 drives the other releasing device 5-2 to drive the limiting device 5-1 to make the iron plate move downward again and fix its position during the resetting process of the other stamping column 3-2.
