Abstract

The invention belongs to the field of design and manufacturing of punching dies, and particularly relates to a bending die.The bending die comprises a lower die base which is fixedly arranged and an upper die base which reciprocates up and down.The upper die base is provided with male dies and a pressing plate.Each male die comprises a swing arm and a pulley, wherein the upper end of the swing arm is hinged to the upper die base, and the pulley is rotationally arranged at the lower end of the swing arm.The lower die base is provided with female dies.Each female die is provided with an inclined groove.The opening of each inclined groove is right opposite to the corresponding pulley.When the upper die base moves downwards, the pulleys can guide the lower ends of the swing arms to swing along the inclined grooves.The male dies swing along the inclined grooves in the downward pressing process, a workpiece is bent to be formed, the workpiece is transversely drawn out from the side when released from the die, the workpiece is formed at a time, production efficiency is greatly improved, and meanwhile machining precision is remarkably improved.

Description

A kind of bending die tool

Technical field

The invention belongs to stamping Die Design and manufacture field, be specifically related to a kind of bending die tool.

Background technology

The subject matter that closing in shape workpiece faces in punch forming process is to be difficult to the demoulding, in prior art, often adopt the method for Multi-step forming to process this type of part, but, Multi-step forming not only has a strong impact on production efficiency, and part needs to carry out multiple clamping, this can be substantially reduced the machining accuracy of part, causes that finished workpart rate is not high.

Summary of the invention

It is an object of the invention to provide one and can make closing in shape workpiece one-shot forming, and be easy to the bending die tool of the demoulding.

For achieving the above object, the invention provides techniques below scheme: a kind of bending die tool, including the die shoe being fixedly installed and the upper bolster pumped, described upper bolster is provided with punch and holding pad, described punch includes swing arm and pulley, described swing arm upper end is hinged with upper bolster, and described pulley rotation is arranged on swing arm lower end;Described die shoe is provided with die, and described die is provided with skewed slot, and described pulley is just arranged by the notch of described skewed slot, and when upper bolster is descending, pulley can guide swing arm lower end edge skewed slot to swing;

Preferably, described holding pad vertically slides relative to upper bolster setting, and described upper bolster is provided with guide hole, and described holding pad is positioned at guide hole, is additionally provided with stage clip in described guide hole;

Preferably, described die being additionally provided with locating pin, described holding pad is provided with the hole, location coordinated with locating pin;

Preferably, described punch and skewed slot are equipped with two groups, see along pulley axis direction, and two groups of skewed slots are that inverse Ba type is arranged;

Preferably, described locating pin is vertically flexible is arranged;

Preferably, described female bottom is provided with a cavity, described locating pin lower end is positioned at cavity, locating pin is connected with a push pedal, described push pedal is through to outside die, and push pedal is slided setting in the horizontal direction, and push pedal the inner is provided with slope, when push pedal slid inward, slope can by locating pin jack-up gradually;

Preferably, described locating pin lower end is arranged with back-moving spring, and the two ends of described back-moving spring are resisted against between head of screw and cavity roof;

Preferably, described push pedal outer end is provided with handle;Described handle is provided with annular knurl;Described die is affixed by bolt and die shoe.

The method have technical effect that: pressing through under punch in journey and swing along skewed slot, make workpiece bending forming, during the demoulding, workpiece is extracted out from the side of the transverse, workpiece one-shot forming, substantially increasing production efficiency, machining accuracy is also significantly improved simultaneously.

Accompanying drawing explanation

Fig. 1 is the front view of the present invention;

Fig. 2 is the right view of die shoe of the present invention.

Detailed description of the invention

Following embodiment is to further illustrate using as the explaination to the technology of the present invention content for present invention; but the flesh and blood of the present invention is not limited in described in following embodiment, those of ordinary skill in the art and can should know any simple change based on true spirit or replacement all should belong to protection domain of the presently claimed invention.
