Description

Disk sieve aperture subregion perforating die

Technical field

The utility model belongs to the perforating die technical field, is specifically related to a kind of disk sieve aperture perforating die.

Background technology

The perforating die of prior art, all disposable punching press is finished, but for the workpiece that large quantities of apertures are arranged, all there is certain problem in disposable punching out for the size of stamping press, the vibration of workpiece etc., and therefore once the someone has invented the mould of height red needle structure.

For example China Patent No. 201220087007.8, name is called the utility model patent of " mould with height red needle ", disclose a kind of mould with height red needle, had die ontology, described die ontology is provided with high red needle and the low red needle that is interspersed.This utility model adopts the scheme punching that the height red needle is set at interval, the red needle of this structure can be run into red needle length and is difficult to calibration when mould is adjusted, because uneven its end face of length can't be used the surface grinding machine reconditioning, this can be because workpiece always be attached on the red needle when punching end workpiece takes off material, and long red needle postpones to take off material generation deflection frangibility, and a red needle also is the thing that very bothers even this class mould fractures; Also having is exactly need reprocess when the wearing and tearing of red needle cutting edge, and this interval arranges the structure of height red needle can not use the surface grinding machine reconditioning too.

Summary of the invention

The utility model technical issues that need to address are that the interval that overcomes prior art arranges the existing deficiency of perforating die of height red needle, provides a kind of and not only has the advantage of length red needle but also make things convenient for reconditioning and durable sieve aperture subregion perforating die in enormous quantities.

The purpose of this utility model is achieved by following technical proposals: a kind of disk sieve aperture subregion perforating die, comprise upper die and lower die, it is characterized in that, patrix comprises upper bolster and convex template, and convex template is provided with several impartial fanned partitions, is provided with a collection of red needle in each subregion, red needle length in the same subregion is identical, the length of the red needle in the different subregions is unequal mutually, is provided with stripper plate below the convex template, and stripper plate is provided with the through hole that cooperates with red needle; Counterdie comprises concave template, and concave template is provided with the die hole corresponding with whole red needles, and upper die and lower die are provided with the reference column device at the position between the adjacent sectors territory.

Several technology locating holes are arranged on the workpiece, these several locating holes are enclosed within on the guide pillar; Patrix down dashes because the length difference of red needle, at first be one in the sector region the red needle contact workpiece and cooperate punching with the die hole of counterdie, and then be second red needle contact workpiece punching in the sector region, move successively in all the other zones; Red needle length in the same sector region is identical, relies on mutually when taking off material, avoids indivedual red needles to fracture or bending; Be divided into several sector regions by the echelon punching, can avoid stamping press to concentrate and apply, alleviate the stamping machine maximum load, can select the littler stamping machine of rated pressure in other words for use, and can prevent that stamping machine and mould from vibrating.

As preferably, the die hole is ladder-type structure, and the upper end of ladder-type structure is the cutting edge of die adaptive with drift, and the lower end of ladder-type structure is the furfur hole, and the aperture in furfur hole is greater than the aperture of cutting edge of die.

As preferably, be connected with hexagon socket head cap screw above the stripper plate, hexagon socket head cap screw cooperates with convex template and upper bolster activity, and the head of hexagon socket head cap screw cooperates with the counterbore of upper bolster is movable.

As preferably, the reference column device comprises the reference column that is fixed in lower bolster and is arranged at reference column hole on the stripper plate.

As preferably, red needle is ladder-type structure, and the through hole that cooperates with red needle on the stripper plate is same ladder-type structure.Ladder-type structure is conducive to shorten red needle head elongated portion, improves stability and the bend resistance intensity of red needle head.

As preferably, described fanned partition is that trisection distributes.

As preferably, the length of the red needle in the adjacent sectors differs 1~3mm successively.

As preferably, the outside left that is positioned at whole sector regions between the upper and lower mould is arranged with two secondary guide pin bushing guide pillars.

The beneficial effects of the utility model are:

1, the progressive punching of subregion alleviates stamping press, avoids the punch press overload to cause vibration;

2, same regional red needle is isometric, is convenient to adjust and reconditioning, can prevent that red needle from fractureing or bending.
