For solving the problems of the technologies described above, a kind of puncher for spacer strip die device that the utility model provides, for two guide pillar structures, comprise upper bolster and die shoe and die shank, described die shank is assemblied in upper bolster centre, its mounted inside has mobilizable bar of beating, the guide pin bushing that is provided with symmetrical guide pillar between described upper bolster and die shoe and matches with guide pillar, upper bolster is connected with push pedal from top to bottom, upper die plate, upper mould fixed plate, blanking die, die shoe is connected with counterdie backing plate from lower to upper, counterdie fixed head, rubber washer and stripper, described blanking die middle part offers shoulder hole, and the ejector coordinating with described shoulder hole is installed, described ejector is socketed on piercing punch outside, this ejector upper end is connected with push rod, push rod upper end is connected with push pedal, push pedal is movably connected in upper bolster, push pedal upper end with make bar and be connected, corresponding position, described blanking die below is provided with punch-die, punch-die is connected with die shoe by counterdie fixed head, punch-die outside is socketed with stripper, stripper is flexibly connected with die shoe by unloading bolt, between stripper and die shoe, be provided with rubber washer, described rubber washer, between stripper and counterdie fixed head, offers dumping pit on described punch-die.

Preferably, the dumping pit end positions of described punch-die offers screwed hole, and is fixed on counterdie backing plate by trip bolt.

Preferably, described dumping pit is the shoulder hole that size is different, and its small end matches with the size of piercing punch.

Preferably, described counterdie backing plate and die shoe middle part all offer through hole, and its size is consistent with the large end of dumping pit.

Preferably, described upper die plate, upper mould fixed plate, blanking die, counterdie backing plate, counterdie fixed head, stripper are cylindrical.

By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: the puncher for spacer strip die device that the utility model provides, integrate blanking and punching two procedures, head part, discharging are conveniently, and reduced the resetting of workpiece, production efficiency is high, reduced manpower simultaneously.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:

As Figure 1-3, the utility model provides a kind of puncher for spacer strip die device, for two guide pillar structures, comprise upper bolster 1 and die shoe 2 and die shank 3, described die shank 3 is assemblied in upper bolster 1 centre, its mounted inside has mobilizable bar 4 of beating, the guide pin bushing 6 that is provided with symmetrical guide pillar 5 between described upper bolster 1 and die shoe 2 and matches with guide pillar 5, upper bolster 1 is connected with push pedal 7 from top to bottom, upper die plate 8, upper mould fixed plate 9, blanking die 10, die shoe 2 is connected with counterdie backing plate 11 from lower to upper, counterdie fixed head 12, rubber washer 13 and stripper 14, described blanking die 10 middle parts offer shoulder hole, and the ejector 15 coordinating with described shoulder hole is installed, described ejector 15 is socketed on piercing punch outside 16, these ejector 15 upper ends are connected with push rod 17, push rod 17 upper ends are connected with push pedal 7, push pedal 7 is movably connected in upper bolster 1, push pedal 7 upper ends with make bar 4 and be connected, corresponding position, described blanking die 10 belows is provided with punch-die 18, punch-die 18 is connected with die shoe 2 by counterdie fixed head 12, punch-die 18 outsides are socketed with stripper 14, stripper 14 is flexibly connected with die shoe 2 by unloading bolt 19, between stripper 14 and die shoe 2, be provided with rubber washer 13, described rubber washer 13 is between stripper 14 and counterdie fixed head 12, on described punch-die 18, offer dumping pit 181, dumping pit 181 end positions of described punch-die 18 offer symmetrical screwed hole 182, and be fixed on counterdie backing plate 11 by trip bolt 20, described dumping pit 181 is the shoulder hole that size is different, its small end matches with the size of piercing punch 16, described counterdie backing plate 11 all offers through hole with die shoe 2 middle parts, its size is consistent with the large end of dumping pit 181, described upper die plate 8, upper mould fixed plate 9, blanking die 10, counterdie backing plate 11, counterdie fixed head 12, stripper 14 is cylindrical.
