Abstract
The invention discloses a blanking bending compound die comprising an upper die base, a lower die base, two outer male dies, two outer female dies, an inner male die and two inner female dies, wherein the inner male die is fixedly arranged on the upper die base; the outer male dies are movably arranged on the upper die base through guide sleeves; the two outer male dies are respectively located at two sides of the inner male die; limit caps are fixedly arranged at upper ends of the outer male dies; an elastic body I is arranged between the limit caps and the upper die base; the outer male dies are also provided with limit pins; the limit pins are located at bottoms of the guide sleeves; the inner female dies are fixedly arranged on the lower die base; and the outer female dies are fixedly arranged on the inner female dies. The blanking bending compound die provided by the invention is capable of increasing the stamping force of the first-stage process i.e. blanking, so that the processing property of the compound die is increased and the impact force provided by a punch press can be reduced.
Description
Technical field
The present invention relates to the cold punching technology processing technique field, be specifically related to a kind of blanking bending compound die.
Background technology
Compound die can be in the one stroke of punch press, finish a plurality of operations such as blanking, punching, it is a kind of efficient, punch process mould of saving, therefore the compound die of development of new as much as possible, improving the utilization rate of compound die, is the important way that reduces the cold punching technology processing cost, enhances productivity.
Existing blanking bending compound die and since design and installation multistage spring, therefore in order to guarantee higher punching press dynamics, need punch press that higher impulse force is provided, cause having reduced the mold use life-span, and production cost is high, processing safety is low, remains further perfect.
Summary of the invention
The object of the present invention is to provide a kind of blanking bending compound die, can improve first order operation is the punching press dynamics of blanking, thereby has improved the processing characteristics of compound die, and can reduce the impulse force that punch press provides.
To achieve these goals, the technical scheme of the present invention's proposition is:
A kind of blanking bending compound die, comprise upper bolster, die shoe, outer punch, outer die, interior punch, interior die, described interior punch is fixedly arranged on described upper bolster, described outer punch is movably set in described upper bolster by guide pin bushing, described outer punch is two and lays respectively at interior punch both sides that described outer punch upper end is installed with limited cap, is provided with elastomer one between described limited cap and the upper bolster, described outer punch also is provided with spacer pin, and described spacer pin is positioned at the guide pin bushing bottom; Described interior die is fixedly arranged on the described die shoe, and described outer die is fixedly arranged on the described interior die.During work, upper bolster moves downward, and under the effect of spacer pin and guide pin bushing, outer punch keeps the dynamics downward punching press identical with punch press, thereby finishes the blanking operation; Then take off spacer pin, upper bolster continues to move downward, and outer punch upwards shrinks, thereby interior punch and indent mold pressing are closed and finished bending operation.
As the further improved blanking bending compound die of the present invention, described elastomer one is spring or spring glue.
As the further improved blanking bending compound die of the present invention, described outer punch lower end is provided with movable ram, and described movable ram is movably set in outer punch lower end by rotating dog.Described structure only needs the outer punch of rotation and spacer pin after the blanking operation is finished, make spacer pin aim at the groove of guide pin bushing, can continue bending operation, and simple operation has improved production efficiency.Because outer punch lower end is provided with rotating dog, guaranteed that therefore outer punch does not affect the state of movable ram in rotation, namely movable ram can realize rotation with respect to outer punch.
As the further improved blanking bending compound die of the present invention, bottom, described interior die hole chamber is provided with jigger pin, is provided with elastomer two between described jigger pin and the described die shoe.Described structure can realize the automatic ejection of workpiece, thereby enhances productivity.
As the further improved blanking bending compound die of the present invention, described elastomer two is spring or spring glue.
Blanking bending compound die provided by the present invention, can improve first order operation is the punching press dynamics of blanking, thereby has improved the processing characteristics of compound die, and can reduce the impulse force that punch press provides, thereby cut down finished cost, improve processing personnel's processing safety.

The specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples the present invention is done to describe in further detail, this embodiment only is used for explaining the present invention, does not consist of the restriction to protection domain of the present invention.
Shown in Fig. 1-4, the blanking bending compound die that present embodiment provides, comprise upper bolster 1, die shoe 2, outer punch 3, outer die 4, interior punch 5, interior die 6, described interior punch 5 is fixedly arranged on described upper bolster 1, described outer punch 3 is movably set in described upper bolster 1 by guide pin bushing 7, described outer punch 3 is two and lays respectively at interior punch 5 both sides, described outer punch 3 upper ends are installed with limited cap 8, be provided with elastomer 1 between described limited cap 8 and the upper bolster 1, described outer punch 3 also is provided with spacer pin 10, and described spacer pin 10 is positioned at guide pin bushing 7 bottoms; Described interior die 6 is fixedly arranged on the described die shoe 2, and described outer die 4 is fixedly arranged on the described interior die 6.Described elastomer 1 is spring or spring glue.
During work, upper bolster 1 moves downward, and under the effect of spacer pin 10 and guide pin bushing 7, outer punch 3 keeps the dynamics downward punching press identical with punch press, thereby finishes the blanking operation; Then take off spacer pin 10, upper bolster 1 continues to move downward, and outer punch 3 upwards shrinks, thereby interior punch 4 is finished bending operation with interior die 5 pressings.
