The implication marked in figure: 1-connecting plate, 2-lower bolster, 3-lower bolster, 4-forming punch fixed head, 5-die, 6-stripper, 7-forming punch, 8-location-plate, 9-punch, 10-jacking block, 11-locating piece, 12-punch retainer, 13-upper padding plate, 14-hollow sheeting, 15-cope match-plate pattern, 16-die shank, 17-makes bar, and 18-re-packs, 19-drift, 20-elastic device polyurethane, 21-connecting rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1 be the structural representation of a kind of composite mould structure for Flange Forming of the present utility model, the utility model proposes a kind of composite mould structure for Flange Forming, comprise connecting plate 1, lower bolster 2, lower bolster 3, upper padding plate 13, cope match-plate pattern 15, lower bolster 2 is arranged on connecting plate 1, lower bolster 3 is arranged on lower bolster 2, cope match-plate pattern 15 is arranged at the top of upper padding plate 13, hollow sheeting 14 is provided with between cope match-plate pattern 15 and upper padding plate 13, lower bolster 3 is provided with forming punch fixed head 4, die 5 is provided with above forming punch fixed head 4, upper padding plate 13 bottom is provided with punch 9, lower bolster 2, lower bolster 3, upper padding plate 13, cope match-plate pattern 15, forming punch fixed head 4 inside has cavity.
The cavity of cope match-plate pattern 15 is provided with die shank 16, and die shank 16 inside is provided with makes bar 17, and the bottom making bar 17 is provided with and re-packs 18; Forming punch fixed head 4 internal cavities is provided with forming punch 7; The periphery of punch 9 is fixedly installed punch retainer 12, and the inner circumferential of punch 9 is provided with drift 19, is provided with jacking block 10 between drift 19 and punch 9, is provided with locating piece 11 between jacking block 10 and punch 9; The inner circumferential of die 5 is fixedly installed stripper 6; The radial dimension of lower bolster 2 is greater than the radial dimension of lower bolster 3, connecting plate 1; Connecting plate 1 is two-layer and is linked together by connecting rod 21, is provided with elastic device polyurethane 20 between connecting plate 1.
Assembling process is as follows: during counterdie assembling, first forming punch 7(is comprised forming punch fixed head 4 and lower bolster 3) be placed on lower bolster 2 by direction, outside forming punch 7, put die 5, on die 5, load onto location-plate 8; Then with screw and parallel clips clamping, match and squeeze into pin; Finally below lower bolster 2, load stripper bolt, in die 5, stripper 6 is installed, makes stripper 6 parallel with die 5; Below lower bolster 2, connecting plate 1 is installed again, and polyurethane rubber, load connecting rod 21, polyurethane rubber is clamped; First jacking block 10 is put into punch 9 during patrix assembling, drift 19 and punch retainer 12 are bumped in punch 9; Again punch 9 and guide pillar are bumped in punch retainer 12; Then position upper padding plate 13 being aimed at punch retainer 12 is put well, and the cope match-plate pattern 15 that closes, and will re-pack 18 to put into hollow sheeting 14, tightens jacking block bolt; Cope match-plate pattern 15, hollow sheeting 14, upper padding plate 13, punch retainer 12 clamp by following parallel clips; Refill die shank 16, and after pushing device is assembled, in insert molding delthyrium; Finally close up patrix, squeeze into pin, use screw fastening.
The course of work is as follows: during work, and be placed on by the blank that stamping-out is good on location-plate 8 on die 5, patrix is descending.First be that punch 9 contacts with blank, carry out flangikng, and it be descending to promote stripper 6, keep a close watch on the downward polyurethane 20 that compresses of connecting plate 1 by unloading bolt and make it be out of shape, forming punch 7 also contacts with blank simultaneously, upwards carries out drawing to blank.When patrix continues descending, flangikng can terminate, but forming punch 7 can continue upwards drawing blank, to a certain extent, drift 19 can go out a bottom outlet on blank, and forming punch 7 starts to carry out circular cross-esction immediately, and promote jacking block 10 and move upward, promote to re-pack 18 together to move upward together with making bar 17 by unloading bolt, when going downwards to certain distance, circular cross-esction and part mid portion are shaped end.When patrix starts backhaul, stripper 6 will be up and return to origin-location gradually along with patrix, and forcing press dnockout cross bar can beat lower rod-knocking 17 simultaneously, promotes jacking block 10 descending, and then part is released from the inner chamber die of punch 9, complete the production overall process of a flange.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
