The upper die holder 1 moves up and down to drive the slotting tool 7 to move up and down.

A stripping plate 5 is arranged below the stripping plate 4, a sliding block seat 8 is arranged in the stripping plate 5, and the lower end of the slotting tool 7 penetrates through the sliding block seat 8. A slide block 10 is arranged below the slide block seat 8, and an inclined pushing block 22 matched with the lower end of the slotting tool 7 is arranged on the left side in the slide block 10. The slotting tool 7 moves upwards, the slotting tool 7 is contacted with the oblique pushing block 22, and the sliding block 10 is driven to move leftwards. The lower surface of the slotting tool 7 is of an upper inclined surface structure, the upper part of the sliding block 10 is provided with a lower inclined surface structure matched with the upper inclined surface structure, and the slotting tool 7 moves downwards and can drive the sliding block 10 to move rightwards through the inclined surface matching of the upper inclined surface structure and the lower inclined surface structure. The lower end of the slide block 10 is connected with a punch 12, and the slide block 10 is connected with the punch 12 through a key block 11. The movement of the slide 10 in turn moves the punch 12.

A stripping block 6 is vertically arranged in the sliding block seat 8, the stripping block 6 is positioned on the right side of the punch 12, and a sliding block limit 9 is arranged on the left side of a sliding block 10 in the sliding way.
