Description

The portable fine blanking die of punch

Technical field

The utility model relates to the portable fine blanking die of a kind of punch.

Background technology

Stamping-out is a kind of stamping procedure utilizing punch die to make part material or operation part and be separated with another part material, operation part or waste material, stamping-out is that shearing, blanking, punching, punching lack, rush groove, cutting, cutter are cut, trimming, cut tongue, incision, the separation circuit such as trimming general name. Stamping-out is except as except getting the raw materials ready, being usually used in directly processing packing ring, bicycle chainwheel, instrument gear, cam, shift fork, instrument panel, and the siliconized plate on motor, electrical equipment, the connector assembly etc. in unicircuit. The stamping-out mode generally adopted at present is that blank is placed in lower cavity die top, and punch is descending directly carries out punching press to blank, namely completes stamping-out after the waste material blanking that stamping-out falls. Often there are some problems in the workpiece of the stamping-out gained adopting this just common: it shears end face has and compare coarse zone of fracture, and with certain gradient, but also may there is collapse angle, burr etc., the workpiece quality processed is poor.

Practical novel content

The utility model is intended to provide a kind of punch portable fine blanking die, and the quality problems such as end face is more coarse sheared by the workpiece gone out to solve existing cutting die stamping-out.

The portable fine blanking die of punch in this scheme, comprise lower die holder, lower die holder has vertical up big and down small ladder hole, the ladder in ladder hole is fixed with backing plate, the top of backing plate is provided with gear ring pressing plate, being provided with in the lower section of lower die holder can the slide block of vertical motion, the top of slide block is arranged with two push rods with erecting of slide block to medullary ray, two push rods are used for applying stamping-out power to convex-concave mould, hole was had in the middle part of gear ring pressing plate, convex-concave mould passed hole, patrix seat is positioned at the surface of lower die holder, the bottom of upper die holder is fixed with the blanking die of ring-type, the top of upper die holder is provided with upper plug, the lower end of upper plug and push pedal are fixed, push pedal and two push rods are fixed, the lower end of push rod and upper male mould are fixed, upper male mould is through blanking die, upper male mould is also provided with piercing punch.

The utility model has the advantage of: during work, from side direction, blank is sent into the top of convex-concave mould and gear ring pressing plate, then upper plug drives upper male mould, upper die holder to drive blanking die descending, blank is compressed by the flanging power of gear ring pressing plate and blanking die, and slide block and upper plug move in the same way, drives convex-concave mould and upper male mould that blank is carried out stamping-out simultaneously, after stamping-out, upper plug drives row on upper male mould, and upper die holder drives row on blanking die, and the blank good by stamping-out and waste material are released.

The utility model has the advantage of: by gear ring pressing plate and blanking die to the compression of blank, can prevent blank from outwards moving in footpath when upper male mould is descending, blank is under the extruding of convex-concave mould, gear ring pressing plate and upper male mould, improve the plasticity of material, inhibit the generation shearing end capacity check, can reduce and even eliminate coarse zone of fracture, it is to increase work pieces process quality.

Further, being fixed with vertical guide pillar on lower die holder, upper die holder has vertical guiding hole, when closing mould, guide pillar can be inserted in guiding hole. By guide pillar and when being engaged in the motion of upper die holder of guiding hole, it is had the effect of guiding, makes conjunction mould position more accurate.

Further, in guiding hole, it is provided with spring. Spring is set, when blanking die is descending, there is shock absorption, prevent the instantaneous impact of blanking die excessive and blank is caused damage.

Further, being provided with flange on the top of upper male mould, the upper surface of gear ring pressing plate can offset with the lower surface of flange. The motion of blanking die is had upper stroke limit effect by flange.
