[0025] In this embodiment, the driving assembly includes a moving groove 13 opened at the top of the moving seat 4, and moving blocks 14 are slidably connected to both sides of the inner wall of the moving groove 13. The two moving blocks 14 are fixedly connected to the moving plate 6, and a hydraulic rod 15 is fixedly connected between the two moving blocks 14;

[0026] The hydraulic rod 15 is started to move the moving block 14, thereby moving the moving plate 6 inward, thereby completing the clamping and limiting of the metal sheet, facilitating the subsequent stamping operation.

[0027] In this embodiment, the inner wall of the base 1 is fixedly connected with a first electric push rod 16 and a second electric push rod 18, respectively; the telescopic end of the first electric push rod 16 is fixedly connected with a first guide plate 17; the first guide plate 17 is slidably connected to the base 1; the first guide plate 1 is limited by the base 1 to enable it to slide stably.

[0028] In this embodiment, the telescopic end of the second electric push rod 18 is fixedly connected to a second guide plate 19, the second guide plate 19 is slidably connected to the base 1, and the second guide plate 19 is arranged above the first guide plate 17;

[0029] The second electric push rod 18 moves with the second guide plate 19 and limits the second guide plate 19 through the base 1 to enable it to move stably.

[0030] In this embodiment, a guide post 20 is provided between the first guide plate 17 and the second guide plate 19, and the guide post 20 is fixedly connected to the moving seat 4;
