Abstract

The utility model discloses a compensation shearing die for a punching plate. The compensation shearing die comprises an upper die part and a lower die part. A flitch is arranged between the upper die part and the lower die part. The lower die part is fixed, and the upper die part can move up and down to punch the flitch. The upper die part comprises an upper die base, an upper die substrate, a plunger chip and a pressing plate. The lower die part comprises a lower die base, a lower die substrate and a lower die notch. The cross section of the plunger chip is in a wave shape, the cross section of the lower die notch is in a wave shape, and the plunger chip is embedded into the lower die notch to punch a workpiece with the edge in a wave shape. The improvement is carried out based on the fact that the traditional blanking and shearing technology only can be used for punching a workpiece with the edge in a line shape, the utilization rate of a material is greatly improved, and production cost is saved.

Description

A kind of compensatory shear mould of punching press plate

Technical field

The utility model relates to decompressor, refers in particular to a kind of compensatory shear mould of punching press plate.

Background technology

Stamping-out is to utilize punch die to make part material or the process part processing a kind of stamping procedure separated with another part material, process part processing or waste material.Stamping-out is that shearing, blanking, punching, punching lack, jet-bedding, dissect, cut a hole cut, trimming, the general name of cutting the separation circuits such as tongue, incision, trimming.Stamping-out is to utilize the cutting edge of punch die to make plate produce detrusion separated along certain outline line.Stamping-out shared ratio in punching production is maximum.

In prior art, stamping-out material shear line is generally straight line, can only production rectangle plate, and its maximum profile depends on that punching parts launches full-size afterwards, for workpiece in irregular shape, add and often need man-hour stamping-out just can obtain final shape many times, and in stamping-out process, material waste is serious.

Utility model content

The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of compensatory shear mould for punching press plate is provided.

The technical scheme that the utility model is taked is as follows: a kind of compensatory shear mould of punching press plate, this compensatory shear mould comprises part of the upper die and part of the lower die, between described part of the upper die and described part of the lower die, be provided with flitch, part of the lower die is fixed, part of the upper die moves up and down with stamping-out flitch, wherein: described part of the upper die comprises upper bolster, upper die base, drift and holding pad, described part of the lower die comprises die shoe, lower die base and counterdie otch, the cross section of described drift is undaform, the cross section of described counterdie otch is also undaform, counterdie otch and drift are mutually chimeric, the stamping-out of take forms the workpiece that edge is undaform.

Further, described upper die base and holding pad are arranged on the bottom of upper bolster, and drift is fixed in upper die base.

Further, described upper die base is L-type block, and upper die base in the vertical direction is fixed on upper bolster, and drift in the vertical direction is fixed in the breach of upper die base.

Further, described holding pad is connected on upper bolster by guide pillar and spring, and holding pad slides up and down along guide pillar under the pulling force of spring and thrust, to compress flitch.

Further, described lower die base is arranged on die shoe, and counterdie otch is arranged in lower die base.

Further, described lower die base is L-type block, and lower die base in the vertical direction is fixed on die shoe, and counterdie otch in the vertical direction is fixed in the breach of lower die base.

The beneficial effects of the utility model are:

The utility model be linear workpiece for can only stamping-out in traditional stamping-out shearing technique forming the length of side, and improved, by adopting drift and the counterdie otch of undaform, so that stamping-out forms the workpiece that edge is undaform, when stamping-out workpiece in irregular shape, greatly improve the utilization rate of material, saved production cost.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figures 1 to 4, a kind of compensatory shear mould of punching press plate, this compensatory shear mould comprises part of the upper die and part of the lower die, between described part of the upper die and described part of the lower die, be provided with flitch, part of the lower die is fixed, part of the upper die moves up and down with stamping-out flitch, wherein: described part of the upper die comprises upper bolster 1, upper die base 2, drift 3 and holding pad 4, described part of the lower die comprises die shoe 5, lower die base 6 and counterdie otch 7, the cross section of described drift 3 is undaform, the cross section of described counterdie otch 7 is also undaform, counterdie otch 7 is mutually chimeric with drift 3, the stamping-out of take forms the workpiece that edge is undaform.

Further, described upper die base 2 and holding pad 4 are arranged on the bottom of upper bolster 1, and drift 3 is fixed in upper die base 2.

Further, described upper die base 2 is L-type block, and upper die base 2 in the vertical directions are fixed on upper bolster 1, and drift 3 in the vertical directions are fixed in the breach of upper die base 2.

Further, described holding pad 4 is connected on upper bolster 1 by guide pillar and spring, and holding pad 4 slides up and down along guide pillar under the pulling force of spring and thrust, to compress flitch.
