Beneficial effect

The utility model replaces the bar of beating of patrix with rubber, rigidity is ejected and becomes flexibility and eject, not only saved material but also it ejected more steady, put respectively two block rubbers at the former two push rod places of counterdie simultaneously, original mechanical ejecting mechanism is replaced, simple in structure, save design time, greatly reduce production costs, reduce greatly manufacturing cycle and the production cost of mould.

The accompanying drawing explanation

Accompanying drawing 1 is structural representation of the present utility model.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described further.

Embodiment

As shown in Figure 1, a kind of flexible blanking die, it comprises part of the upper die 1 and part of the lower die 2, part of the upper die 1 comprises upper bolster 101, upper padding plate 102, punch-die fixed head 103 and stripper 104, upper bolster 101, upper padding plate 102, punch-die fixed head 103 is fixed together successively, stripper 104 is contained on upper bolster 101 and is positioned at punch-die fixed head 103 belows by unloading bolt, punch-die 105 is contained on punch-die fixed head 103 through stripper 104, part of the lower die 2 is successively by blanking die 201, lower supporting plate 202, piercing punch fixed head 203, lower bolster 204 and the fixing composition of die shoe 205, it is characterized in that: between described punch-die fixed head 103 and stripper 104, rubber 106 is housed, push rod 107 is through punch-die 105, push rod 107 heads withstand the top board 108 be contained in upper bolster 101 inside grooves, top board 108 upper surfaces are equipped with top board rubber 109, head part plate 206 is contained in the head part plate installing hole 206a of blanking die 201, head part plate 206 bottoms are contained on head part plate rubber 207, head part plate rubber 207 is arranged in lower supporting plate 202 inside grooves, drift 208 is fixed on piercing punch fixed head 203 through head part plate 206.

Described part of the upper die 1 and part of the lower die 2 are by guide pillar guide pin bushing 3 guiding.

On described upper bolster 101, die shank 110 is housed.

Described upper bolster 101, upper padding plate 102, punch-die fixed head 103 are fitted together by screw and pin stationary positioned.

Described blanking die 201, lower supporting plate 202, piercing punch fixed head 203, lower bolster 204 and die shoe 205 are connected with the pin stationary positioned by screw.

Under the effect of forcing press, die shank 110 drives upper bolster 101 and moves downward, by guide pillar guide pin bushing 3 guiding.Thin plate is placed on the upper plane of blanking die 201.Stripper 104 moves downward, and pushes down sheet material.Punch-die 105 moves downward, and stamping falls into and falls into die 10 in the effect of punch-die 105, and punched scrap is stayed punch-die 105.Head part plate 206 moves downward, compressing rubber.After Blanking Shaping, part of the upper die 1 moves upward, and rubber starts uphold to promote head part plate 206, and then heads on product and move upward, and the punched scrap same principle is ejected simultaneously, after stamping-out finishes, takes out product.

The utility model replaces the bar of beating of patrix with rubber, rigidity is ejected and becomes flexibility and eject, not only saved material but also it ejected more steady, put respectively two block rubbers at the former two push rod places of counterdie simultaneously, original mechanical ejecting mechanism is replaced, simple in structure, save design time, greatly reduce production costs, reduce greatly manufacturing cycle and the production cost of mould.
