In the setting mode, the knife-edge plate 2 is arranged under the clamping plate 1, the lower end faces of the clamping plate 1 and the knife-edge plate 2 are provided with the feeding grooves 11 which are respectively the first feeding groove 11 and the second feeding groove 21, the first feeding groove 11 is used for conveying the inner shrinking glue 4, the second feeding groove 21 is used for conveying the steel strip 5, at least two punches 3 are installed in the clamping plate 1, the lower ends of the punches 3 extend out of the clamping plate 1 and penetrate through the knife-edge plate 2, the punches 3 can obtain the driving force in the vertical direction through the connected external driving mechanism, so that the inner shrinking glue 4 conveyed by the first feeding groove 11 can be punched and then further downwards, the inner shrinking glue 4 is punched to the steel strip 5 conveyed by the second feeding groove 21, the steel strip 5 is further provided with the heating sheets 6 corresponding to the punches 3, the inner shrinking glue 4 can be conducted and heated on the punching press, the inner shrinking glue 4 is tightly attached to the steel strip 5, the inner shrinking glue 4 is attached to the steel strip 5, the hot-pressing mold is also used for reducing the hot-pressing efficiency and the hot-pressing efficiency, and the production efficiency of products are reduced, and the hot-pressing efficiency is reduced.

Referring to fig. 1, in the present embodiment, three punches 3 are provided, each punch 3 has a first step portion 31 protruding outward, the splint 1 is formed with a second step portion (not labeled in the figure) protruding inward, and when the punch 3 is installed in the splint 1, a lower end of the first step portion 31 can abut against an upper end of the second step portion, so that an upper section of the punch 3 can be hung in the splint 1. Preferably, the upper end surface of the punch 3 and the upper end surface of the clamping plate 1 are positioned on the same horizontal plane. In this embodiment, the first step portion 31 is a rectangular parallelepiped, but in other embodiments, the first step portion 31 may also be disposed around the circumference of the main body of the punch 3, so that the entire punch 3 is hung in the splint 1 in a table-like structure.

Specifically, in this embodiment, the clamp plate 1 and the knife-edge plate 2 are correspondingly provided with three cavity holes 7, and a main body of each cavity hole 7 is adapted to a shape required by the corresponding shrink fit 4, for example, the main body of each cavity hole 7 is pentagonal in this embodiment.
