The invention has the beneficial effects as follows: a kind of punching-pressing composite mould of the present invention, blanking, drawing can be made, rush bottom outlet, rush flange hole, trimming is once-combined, so only need 1 secondary mould, blanking, drawing completed before punching and trimming, realize the compound of five operations smoothly, meet the requirement of modern production high accuracy, low cost, high benefit.

Accompanying drawing explanation

Fig. 1 is the structural representation of a preferred embodiment of a kind of punching-pressing composite mould of the present invention.

Detailed description of the invention

Below in conjunction with accompanying drawing, present pre-ferred embodiments is described in detail, to make the advantage of invention and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.

Refer to Fig. 1, the embodiment of the present invention comprises:

A kind of punching-pressing composite mould, this punching-pressing composite mould comprises patrix 16 and counterdie 33, and on the guide pillar 36 of described counterdie 33, cover has the guide pin bushing 18 of patrix 16; Described patrix 16 center that also comprises is provided with bottom outlet punch 9, and the position that patrix 16 avoids bottom outlet punch 9 is provided with flange hole punch 4, and flange hole punch 4 overcoat has upper punch-die 3; The described counterdie 33 that also comprises is provided with the lower punch-die one 31 corresponding with bottom outlet punch 9, flange hole punch 4 and upper punch-die 4, lower punch-die 26 and blanking die 23.

Described patrix 16 also comprises upper bolster 19, upper padding plate 6, punch retainer 5, epirelief die block 2, discharging rubber 20, stripper 22, drawing die 21, push piece plate 1, small rubber block 15, connects push rod 10 and push pedal 13, and described upper padding plate 6, punch retainer 5, epirelief die block 2, discharging rubber 20 and stripper 22 are fixed on upper bolster 19 lower plane after superposing successively; Described epirelief die block 2 is fixed with punch-die 3, and upper punch-die 3 inner sleeve has drawing die 21, and drawing die 21 is provided with small rubber block 15 between plane and punch retainer 5, and drawing die 21 lower plane is provided with push piece plate 1; Described punch retainer 5 is fixed with bottom outlet punch 9 and flange hole punch 4, bottom outlet punch 9 and flange hole punch 4 are successively through small rubber block 15, drawing die 21 and push piece plate 13; Described also comprising between upper padding plate 6 and upper bolster 19 is provided with push pedal 13, push pedal 13 lower plane be connected push rod 10 upper-end contact, connect push rod 10 successively through being against on push piece plate 1 after upper padding plate 6, punch retainer 5, epirelief die block 2, small rubber block 15 and drawing die 21.
