Detailed description of the invention
A kind of hole flanging mold structure, it mainly comprises cope match-plate pattern 1 and lower bolster 2, it is characterized in that described cope match-plate pattern 1 is provided with punch 3, lower bolster 2 is provided with die 4, outwardly formation one round boss of bottom centre of described punch 3, punch center is provided with resigning hole 5, and described die 4 is provided with the keeper 6 matching with described round boss, the center of described keeper 6 is provided with the cylinder 7 matching with resigning hole 5, is provided with a circle flange 8 at die 4 tops along keeper 6 outers.In order to match with described flange 8, in the bottom of punch 3, surrounding's setting of round boss and a circle depressed part 10, and the side of described round boss is the inclined-plane of inclination.In described die 4, be provided with a circular hole, the lower end of keeper 6 is positioned at described circular hole, can slide up and down the bottom outwardly convex of keeper 6 in circular hole, the bottom of described circular hole is provided with the limited block matching with the lower lobes of keeper, and described keeper is also provided with elasticity reset device.The structure of elasticity reset device is as follows: in described keeper 6, be provided with a centre bore, be provided with spring 9 in described centre bore, one end of spring 9 contacts with keeper, and the other end of spring 9 contacts with lower bolster 2.This punch structure, in the time of hole flanging, can play the effect with die guiding.
When use, to be processed is placed on die 4, cope match-plate pattern 1 drives the downward punching press of punch 3, when punch 3 tops are with after to be processed contacts, under the effect of stamping press, the inside indentation of spring 9, the round boss of punch 3 embeds in the circle sunk area between flange 8 and the cylinder 7 on die 4 top keepers 6 simultaneously, cylinder 7 on die 4 top keepers 6 is in the resigning hole 5 of jacking punch 3, thereby on workpiece, forms hole flanging.After machining, on punch 3, lift, when spring 9 resets, drive keeper 6 to rise, until the lower lobes of keeper 6 contacts with the limited block of die 3 interior circular holes, keeper 6 has resetted.
