Description of drawings
Fig. 1, cold stamping compound die structural representation.
1 is upper bolster, and 2 is die shoe, and 3 is die, and 4 is punch, and 5 is stripper, and 6 is stock supporting plate, and 7 is fixed head, and 8 is pin, and 9 is limited block, and 10 is that elastomer one, 11 is a projection, and 12 is buffer stopper, and 13 is that elastomer two, 14 is an elastomer three.
The specific embodiment
In order to deepen to understanding of the present utility model, the utility model is done describing in further detail below in conjunction with drawings and Examples, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
As shown in Figure 1, the cold stamping compound die that present embodiment provided, comprise upper bolster 1, die shoe 2, die 3, punch 4, stripper 5, stock supporting plate 6, described die 3 is fixedly arranged on upper bolster 1 by fixed head 7, described stripper 5 is movably set in described fixed head 7 by pin 8, described pin 8 is two and is symmetricly set in described die 3 both sides, described pin 8 tops are installed with limited block 9, described fixed head 7 is provided with the through hole that supply and marketing 8 is passed through, and described through hole is divided into coaxial two sections, the epimere diameter is more than or equal to the diameter of described limited block 9, and the hypomere diameter is more than or equal to the diameter of described pin 8 and less than the diameter of described limited block 9; Described punch 4 is fixedly arranged on described die shoe 2, and described stock supporting plate 6 is being provided with elastomer 1 above the die shoe 2 and between described stock supporting plate 6 and the die shoe 2, and described elastomer 1 is two and is symmetricly set in described punch 4 both sides; Described stock supporting plate 6 is provided with projection 11, and described protruding 11 are positioned at described die 3 belows and punch 4 both sides.Described elastomer 1 is a spring.
During work, die 3 together presses down with stripper 5, when projection 11 external diameter during less than die 3, workpiece carries out flange and pull and stretch operation under the effect of projection 11 and stripper 5, when the external diameter of projection 11 equals die 3, workpiece carries out the blanking operation under the effect of projection 11 and stripper 5, this moment, in fact stripper 5 brought into play the effect of diel; When punch 3 continued to descend with stripper 5, stock supporting plate 5 began to descend, thereby makes punch 4 and die 3 pressings, promptly forms operation.
Further improve as present embodiment, described stock supporting plate 6 is provided with buffer stopper 12, and described buffer stopper 12 is positioned at described protruding 11 the outside, is provided with elastomer 2 13 between described buffer stopper 12 and the stock supporting plate 6.Described elastomer 2 13 is a spring.By said structure can be effectively fixing workpiece, avoid workpiece slippage dislocation.
