Detailed ways

The invention is further described in the following with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, and are not intended to limit the scope of the present invention.

As shown in FIG. 1 to FIG. 4, a punched stable rapier belt stamping processing die includes an upper module and a lower module, and the upper module includes an upper template 2, a punch fixing plate 3, a punch 4, and an unloading a die plate 5 to which a die holder 1 is attached, the punch fixing plate 3 is mounted on a lower surface of the upper die plate 2, and the upper surface of the discharge plate 5 is connected with a discharge spring 11 At the lower end, the upper end of the discharge spring 11 is fixed in the punch fixing plate 3, the punch 4 passes through the discharge plate 5 and the punch fixing plate 3, and the top end thereof and the upper template 2 The lower surface is connected; the lower module includes a female touch 7 and a lower die plate 9, the female die 7 is mounted on the upper surface of the lower die plate 9, and the positioning die is passed between the female die 7 and the lower die plate 9 8 fixed, the female mold 7 is provided with a hole for the head of the punch 4 to pass through, the guiding pin 6 passes through the discharging plate 5 and the punch fixing plate 3, the guiding pin 6 The top end is coupled to the lower surface of the upper die plate 2, and the lower end of the pilot pin 6 is inserted into the female touch 7.
