Description
Technical field
The utility model relates to a kind of shaped device of strength plates.
Background technology
At present, domestic in punching course, the mild steel less for yield strength adopts one time punching molded substantially, in the time that the yield strength of sheet material is larger when (being generally greater than 800N/mm2), because sheet material is difficult to plastic deformation, screen resilience is large, the existing basic post forming that adopts, basic forming for the first time, second-order correction moulding.The appearance poor that makes like this product, machining accuracy is low, and the cost of processing is high simultaneously.In existing domestic auto parts and components processing industry, having most is all stamping parts, for alleviating the weight of vehicle body, stamping parts adopts high-intensity board making, precision to product and appearance requirement are more and more higher simultaneously, and due to the intensified competition of enterprise, each enterprise must be in ensureing weight simultaneously, reduce production costs, as post forming is made into one-shot forming.
High-strength panel is placed on and on blank holder, up withstands patrix, when simultaneously patrix down moves to certain position with high-strength panel and blank holder, punch withstands high-strength panel and moves in the molding concave die of patrix, the high-strength panel of periphery is and then toward the motion of molding concave die place, high-strength panel now is only subject to the power that press on punch top, high-strength panel deforms, in the time that the yield strength of high-strength panel is larger, only there is part plastic deformation, all the other are deformed into rigid deformation, so the high-strength panel after moulding produces resilience.Be not inconsistent with the requirement of moulding, need to revise for the second time punching press.Therefore, need to make rational improvement to prior art labor strength is high, and operating efficiency is low.
Utility model content
For the weak point existing in the problems referred to above, the utility model provides a kind of shaped device of strength plates.
For achieving the above object, the utility model provides a kind of shaped device of strength plates, comprising:
Patrix, described patrix bottom surface has multiple shaping grooves, and the patrix bottom surface of described shaping groove both sides also has technique groove;

Guide pillar is arranged on described patrix and described counterdie junction, and the guide column sleeve matching with described guide pillar is installed on described blank holder, and described guide pillar both sides are provided with spring.
Further improve as the utility model, described shaping groove lower end is circular arc chamfering.
Further improve as the utility model, described punch and described shaping groove are used in combination.
Preferred as the utility model, described punch is fixed by bolt and described counterdie.
Further improve as the utility model, described rocker piece and described blank holder junction are provided with supporting plate.
Further improve as the utility model, described shaping groove is identical with described punch quantity.
Further improve as the utility model, described technique groove is identical with described rocker piece quantity.
Further improve as the utility model, between described counterdie and described blank holder, be reserved with space.
Further improve as the utility model, the setting height(from bottom) of described punch is greater than the setting height(from bottom) of described rocker piece, and difference in height is determined by the thickness of described pad.
Compared with prior art, the utlity model has following advantage:
1, the utility model adopts float drawing mechanism, makes high-strength panel in punching course, produce bidirectional stress, dwindles the region of plastic deformation simultaneously, and decreasing rebound amount, makes high-intensity sheet material disposable high-precision modeling in the time of punching press;
2, the utility model adopts float drawing mechanism to have easy to operately, can reduce labor strength, with the advantage of increasing work efficiency.
3, ensure the top lifting height of rocker piece by the adjusting of pad, make high-strength plate bidirectional stress in punching course even, simple and convenient.

Detailed description of the invention
As Figure 1-3, the shaped device of a kind of strength plates described in the utility model embodiment, comprising: patrix 1, and described patrix 1 bottom surface has multiple shaping grooves 2, and patrix 1 bottom surface of described shaping groove 2 both sides also has technique groove 4; Described shaping groove 2 lower ends are circular arc chamfering 3.Counterdie 11 is positioned under described patrix 1, described counterdie 11 tops are provided with blank holder 5, described counterdie 11 tops are provided with multiplely to be run through the punch 6 of described blank holder and the rocker piece 7 matching with described technique groove 4 is installed on the blank holder 5 of described punch 6 both sides, described rocker piece 7 lower ends are inserted in described counterdie 11 inside, and described rocker piece 7 lower ends are provided with pad 13; Guide pillar 10 is arranged on described patrix 1 and described counterdie 11 junctions, and the guide column sleeve 9 matching with described guide pillar 10 is installed on described blank holder, and described guide pillar 10 both sides are provided with spring 8.Between described counterdie 11 and described blank holder 5, being reserved with punch 6 described in space is used in combination with described shaping groove 2, described punch 6 is fixing by bolt and described counterdie 11, described rocker piece 7 is provided with supporting plate 12 with described blank holder 5 junctions, described shaping groove 2 is identical with described punch 6 quantity, described technique groove 4 is identical with described rocker piece 7 quantity, the setting height(from bottom) of described punch 6 is greater than the setting height(from bottom) of described rocker piece 7, and difference in height is determined by the thickness of described pad 13.Make high-strength panel in punching course, produce bidirectional stress, dwindle the region of plastic deformation simultaneously, decreasing rebound amount, disposable high-precision modeling; Easy to operate, can reduce labor strength, the advantage of increasing work efficiency, ensures by the adjusting of pad the top lifting height of rocker piece to make high-strength plate bidirectional stress in punching course even, simple and convenient.
When concrete use: in the time that high-strength panel needs punch forming, high-strength panel is placed on blank holder, and spacing by other mechanisms, blank holder up moves, high-strength panel is contacted with patrix, patrix down moves with high-strength panel and blank holder simultaneously, and in the time moving to certain position, punch withstands high-strength panel, continue down motion, now high-strength panel deforms, and the top pressure that part high-strength panel is subject to punch enters in the shaping groove of patrix, and predeformation occurs.In the time that patrix down moves with high-strength panel and blank holder again, the rocker piece of float drawing mechanism withstands high-strength panel, push high-strength panel moves simultaneously in technique groove, when patrix continues down to move with high-strength panel and blank holder, the region that now high-strength panel deforms is in the interval of rocker piece and punch formation, this interval high-strength panel is subject to two-way power (power that press on the power that press on punch top and rocker piece top), produce plastic deformation, springback capacity disappears, the resilience hardly of product after the demoulding, meet the requirement of moulding, one time punching molded.Press on the top of high-strength plate by float drawing mechanism, by two-way drawing, plastic deformation region is diminished, and high-strength plate is perfect plasticity distortion in groove, overcomes the large problem of springback capacity after high-strength plate punching press.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
