The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, a kind of perforating die, comprise upper bolster 5, die shoe 12, four guide pin bushing guide pillars 1, hanger 2, the first piercing punch body 3, the second piercing punch body 4, the 3rd piercing punch body 6, the 4th piercing punch body 7, the first punching concave die body 11, the second punching concave die body 10, the 3rd punching concave die body 9, the 4th punching concave die body 8, upper bolster 5 and die shoe 12 are strip, each corner of upper bolster 5 and die shoe 12 respectively arranges a guide pin bushing guide pillar 1, be furnished with the first piercing punch body 3 in the rectangular area that the guide pin bushing guide pillar 1 of upper bolster 5 forms, the second piercing punch body 4, the 3rd piercing punch body 6 and the 4th piercing punch body 7, be furnished with the first punching concave die body 11 in the rectangular area that the guide pin bushing guide pillar 1 of die shoe 12 forms, the second punching concave die body 10, the 3rd punching concave die body 9 and the 4th punching concave die body 8, the first piercing punch body 3 and the first punching concave die body 11 are supporting, the second piercing punch body 4 and the second punching concave die body 10 are supporting, the 3rd piercing punch body 6 and the 3rd punching concave die body 9 are supporting, and the 4th piercing punch body 7 and the 4th punching concave die body 8 are supporting.

Hanger 2 is made up of hanger cover 13 and bolt 14, and described hanger cover 13 has the endoporus that bolt 14 passes, and the outer surface middle part of hanger cover 13 has groove, and bolt 14 can be hexagon socket head cap screw.This kind hanger 2 adopts the form of hanger cover and bolt combination, bolt is connected with die shoe with the upper bolster of mould, and the hanger cover can adopt the round steel material directly to process, and processing technology is simple, the stock utilization height, bolt adopts standard component, the intensity height, and bearing load is big, the stress of having avoided prior art to produce is concentrated and is caused rupturing, if hanger overlaps long-time service failure, hexagon socket head cap screw still can use, economic security.

This perforating die has four stations, be installed in simultaneously on the mould bases, each station all has dismountable guide, keeper, liftout spare and bolster separately, can dash a part simultaneously on each station, can utilize the lathe tonnage fully like this, reduce and change preface, save time, shorten the process-cycle, reduced operating personnel's workload, improved operating efficiency.
