Detailed Description

To make the objects, contents and advantages of the present utility model more apparent, the following detailed description of the present utility model will be given with reference to the accompanying drawings and examples.

The embodiment provides a continuous blanking and forming die device for a fixed disc, which is structurally shown in fig. 1 and 2, and mainly comprises a lower die plate 1, a female die 2, a first guide rule 3, a stripper plate 4, a male die fixing plate 5, a base plate 6, an upper die plate 7, a guide head 8, a first male die 9, a die shank 10, a second male die 11, a third male die 12, a side edge 13 and a second guide rule 14.

The upper die part comprises a punch fixing plate 5, a base plate 6, an upper die plate 7, a guide head 8, a first punch 9, a die shank 10, a second punch 11, a third punch 12 and a side edge 13. Wherein the bottom end of the die shank 10 is inserted into the top central groove of the upper die plate 7 and is assembled together by screw fastening. The guide head 8 is embedded into the bottom end of the first male die 9 in a transition fit mode, the first male die 9, the second male die 11 and the third male die 12 are embedded into corresponding male die mounting holes on the male die fixing plate 5 in a transition fit mode, and the side blades 13 are embedded into side blade mounting holes on the male die fixing plate 5 in a transition fit mode to play roles in punching blanking and repositioning notch punching. The backing plate 6 is placed above the punch fixing plate 5, the backing plate 6, the punch fixing plate 5 and the bottom of the upper die plate 7 are combined and positioned by using pins, and the upper die plate 7, the backing plate 6 and the punch fixing plate 5 embedded with the punch and the side blades 13 are fastened and combined together by screws.

The lower die part comprises a lower die plate 1, a female die 2, a first guide rule 3, a stripper plate 4 and a second guide rule 14. Wherein the screw holes and the pin holes of the female die 2 are aligned with the positions of the screw holes and the pin holes of the lower die plate 1 and are arranged on the lower die plate 1.
