Fig. 1 is a structural representation of the present invention.
(5) specific embodiment
See Fig. 1; The present invention includes mode structure and following mode structure; Be connected through outer guiding post 56 between last mode structure and the following mode structure, be equipped with on the last mode structure and cut waste material cutter 34, correspondence is equipped with punching part, flange part, semishearing partly and moulding section on last mode structure and the following mode structure.
Last mode structure comprises upper bolster 1, and upper bolster 1 bottom is mounted with upper padding plate 2 and fixed head 3 successively through screw 40; Last mode structure also comprises baffle plate 4 and stripper plate 5; Fixing between baffle plate 4 and the stripper plate 5 through screw 39; Passing through screw such as height such as grade 38 between upper bolster 1, upper padding plate 2, fixed head 3 and baffle plate 4, the stripper plate 5 is connected; Following mode structure comprises die shoe 8; Die shoe 8 is supported in bottom plate 10 through bottom seat pad 9; Be connected through screw 29,28 respectively between bottom seat pad 9 and die shoe 8, the bottom plate 10; Die shoe 8 tops are equipped with lower bolster 7, and lower bolster 6 is installed on the lower bolster 7, and lower bolster 6, lower bolster 7, die shoe 8 connect through screw 16;
Punching partly comprises bullport punching part and flange pre-punched hole part; The bullport punching comprises that partly patrix pilot punch 53 and counterdie bullport go into son 14; Patrix bullport drift 53 is fixed in fixed head 3 through the head countersunk head; The counterdie bullport is gone into son 14 and is fixed on the lower bolster 2 through screw; The flange pre-punched hole comprises that partly patrix pierce punch 52 and counterdie circular hole go into son 15; Patrix pierce punch 52 is fixed in fixed head 3 through screw 51; The counterdie circular hole is gone into son 15 and is fixed on the lower bolster 7;
The turn-up portion branch comprises that the patrix flange goes into son 43 and counterdie flange drift 22, and the patrix flange is gone into son and 43 passed through
The turn-up portion branch comprise the patrix flange go into the son 43 with counterdie flange drift 22; The patrix flange is gone into son 43 and is fixed in stripper plate 5 through screw 44, and it be to push up in the flange that counterdie flange drift 22 is fixed in lower bolster 6,45 through screw 21; It uses the head countersunk head to be fixed on the upper padding plate 2
Semishearing partly comprises patrix semishearing drift 41 and counterdie hemisection die 27; Patrix semishearing drift 41 is fixed in fixed head 3 through screw 42, and counterdie hemisection die 27 is fixed in lower bolster 7 through screw;
Moulding section comprises mold forming drift 36 and counterdie molding concave die 30; Last mold forming drift 36 is fixed in fixed head 3 through screw 37, and counterdie molding concave die 30 is fixed in lower bolster 7;
