Summary of the invention
For solving the problems of the technologies described above, the invention provides and a kind ofly can make punching press product material strip surfacing out, without the diel of the collapse problems such as angle, torsional deformation or fold.
Diel of the present invention, comprise module and lower module, upper module comprises die shank, stripper, upper bolster and upper die plate, wherein upper die plate is arranged on the lower surface of upper bolster, also comprise punching pin backing plate, punch fixing plate and punching pin, punch fixing plate is arranged on the lower surface of punching pin backing plate, punching pin group is located on punch fixing plate, lower module comprises die shoe, counterdie backing plate, lower bolster, wherein counterdie backing plate is arranged on die shoe upper surface, lower bolster is arranged on counterdie backing plate upper surface, upper module also comprises guide pin and guide pin fixed head, guide pin fixed head is arranged on the lower surface of upper die plate, guide pin group is located on guide pin fixed head, stripper is positioned at the below of guide pin fixed head, stripper is connected with guide pin fixed head, between stripper and guide pin fixed head, be connected with the first spring, lower bolster, on lower bolster and die shoe, be provided with pilot hole with the corresponding position of guide pin, upper bolster lower surface is provided with circular groove, upper bolster is provided with manhole, manhole vertically extends to the roof of circular groove from the upper surface of upper bolster, punching pin backing plate and punch fixing plate are positioned in circular groove, die shank is arranged on punching pin backing plate upper surface, and through the manhole on upper bolster, punch fixing plate connects upper die plate by the second spring.
Further, diel of the present invention, the madial wall of circular groove is provided with the first wearing layer.
Further, diel of the present invention, the roof of circular groove is provided with cushion.
Further, diel of the present invention, counterdie backing plate is provided with louvre.
Further, diel of the present invention, lower bolster comprises die cavity, the inner surface of die cavity is provided with the second wearing layer.
Further, diel of the present invention, the second wearing layer inner surface is provided with anticorrosive coat.
Compared with prior art beneficial effect of the present invention is: by said structure, arrange, punching pin is before stamping products material strip, stripper and product material strip and lower bolster fit tightly, thereby product material strip is pressed between stripper and lower bolster, then punching pin carries out punching press to product material strip again, avoid product sheet material strip to suppress in punching course not tight, thereby caused product material strip occur the collapsing problem of angle, fold, surface irregularity.
Accompanying drawing explanation
Fig. 1 is that master of the present invention looks cutaway view;
Fig. 2 is the partial enlarged drawing of A portion in Fig. 1.
In Fig. 1,2,1: upper module; 2: lower module; 101: die shank; 102: stripper; 103: upper bolster; 104: upper die plate; 105: punching pin backing plate; 106: punch fixing plate; 107: punching pin; 108: guide pin; 109: guide pin fixed head; 110: the first springs; 111: the first wearing layers; 112: cushion; 201: die shoe; 202: counterdie backing plate; 203: lower bolster; 204: pilot hole; 205: the second wearing layers; 206: anticorrosive coat; 207: louvre.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
As depicted in figs. 1 and 2, diel of the present invention, comprise module 1 and lower module 2, upper module comprises die shank 101, stripper 102, upper bolster 103 and upper die plate 104, wherein upper die plate is arranged on the lower surface of upper bolster, also comprise punching pin backing plate 105, punch fixing plate 106 and punching pin 107, punch fixing plate is arranged on the lower surface of punching pin backing plate, punching pin group is located on punch fixing plate, lower module comprises die shoe 201, counterdie backing plate 202, lower bolster 203, wherein counterdie backing plate is arranged on die shoe upper surface, lower bolster is arranged on counterdie backing plate upper surface, upper module also comprises guide pin 108 and guide pin fixed head 109, guide pin fixed head is arranged on the lower surface of upper die plate, guide pin group is located on guide pin fixed head, stripper is positioned at the below of guide pin fixed head, stripper is connected with guide pin fixed head, between stripper and guide pin fixed head, be connected with the first spring 110, lower bolster, on lower bolster and die shoe, be provided with pilot hole 204 with the corresponding position of guide pin, upper bolster lower surface is provided with circular groove, upper bolster is provided with manhole, manhole vertically extends to the roof of circular groove from the upper surface of upper bolster, punching pin backing plate and punch fixing plate are positioned in circular groove, die shank is arranged on punching pin backing plate upper surface, and through the manhole on upper bolster, punch fixing plate connects upper die plate by the second spring 113.
