Description
Technical field
The utility model relates to pressing equipment fine blanking die technical field, is specifically related to a kind ofly protect shape fine blanking die for thin-walled stamping parts.
Background technology
Diel is equipment material being carried out to pressure processing use, its operation principle be generally under the effect of punching press, drive the folding of patrix and counterdie by mould and by it between raw material carry out cutting, punching, the setting such as stretching, form stamping parts.According to the operation principle of forcing press, mechanical press and hydraulic press can be divided into.Mechanical press have been moved punching course by motor driven slide, and hydraulic press is by hydraulic principle, drives hydraulic cylinder to move back and forth punching course.Mechanical press work reciprocating frequence is fast, and speed is high, and efficiency is high, but the power produced is less, is generally used for mini-type punching equipment, and punching, shearing technique.The force rate that hydraulic pressure function produces is comparatively large, but speed is comparatively slow, is generally used for stretching, shaping production, also for punching press and the shearing of heavy parts.
Fine blanking die is that current existing product manufactures the novel mould in field.It is combined by the punch-die coordinated up and down usually, and punch-die is fixed by upper padding plate, and upper padding plate and cope match-plate pattern are fixed.Current punched thin-wall part, the step punching press no matter adopted or Multi-step forming formula, capital to part collapse angle produce considerable influence, when this endoporus is near part outer rim, dimensional accuracy and the serviceability of whole product can also be affected, therefore need to develop a kind of mould being applicable to thin-walled punching press on this basis.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency for above-mentioned existence, provides a kind of and protects thin-walled position, reduces plastic deformation during punching press, and that improves the precision of stamping parts protects shape fine blanking die for thin-walled stamping parts.
The utility model solves the technical scheme that its technical problem adopts:
Shape fine blanking die is protected for thin-walled stamping parts, include the upper and lower mould of the male-female clamping stamping parts, patrix comprises cope match-plate pattern, upper padding plate and punch, cope match-plate pattern is fixed with upper padding plate, punch is installed under upper padding plate, punch is provided with drift, counterdie comprises lower bolster, lower bolster and die, lower bolster is fixed with lower bolster, die installed by lower bolster, it is characterized in that: on punch, just multiple punching press station is provided with to the position, multiple hole of stamping parts, each station is equipped with drift, be followed successively by multiple cutting edge drift and multiple forming punching head from outside to inside, described die is inner in corresponding position, each hole site, is also provided with hair down thorn pin, described forming punching head is equipped with and protects shape pin.
In such scheme, described punching press station has three at least.
In such scheme, described shape of protecting is sold for damascene structures is arranged on forming punching head surface, and departs from forming punch position of center line.
In such scheme, the center, end of described forming punching head is provided with bulge-structure.
Principle of the present utility model adopts the punching press of method realization to porous member protecting shape, shear stress time to reduce punching press and plastic deformation stress, stamp out position, inside parts multiple hole at first, then burr is outwelled with dabbing thorn pin, do middle drawing process again, last punch shape is identical with stamping parts, and protects shape pin at Kong Weizhong equipment, completes the punching press to part.
The beneficial effects of the utility model are: can improve stamping-out cross section quality, reduce the plastic stress of multi-hole position stamping-out, improve the mechanical property of stamping parts.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is further described:
As shown in Figures 1 to 4 protect shape fine blanking die for thin-walled stamping parts, include the upper and lower mould of the male-female clamping stamping parts, patrix comprises cope match-plate pattern 1, upper padding plate 2 and punch, cope match-plate pattern 1 is fixed with upper padding plate 2, upper padding plate installs punch 2 times, punch is provided with drift, counterdie comprises lower bolster 4, lower bolster and die 5, lower bolster 4 is fixed with lower bolster, lower bolster is installed die 5, punch is just provided with multiple punching press station to the position, multiple hole of stamping parts, each station is equipped with drift, be followed successively by multiple cutting edge drift 6 and multiple forming punching head 7 from outside to inside, described die 5 inside, in corresponding position, each hole site, is also provided with hair down thorn pin 9, described forming punching head 7 is equipped with and protects shape pin 8.
In the present embodiment, described punching press station has three.
In the present embodiment, described protect shape pin 8 for damascene structures and be arranged on forming punching head 7 surface, and depart from forming punch 7 position of center line.
In the present embodiment, the center, end of described forming punching head 7 is provided with bulge-structure.
More than illustrate and be only Application Example of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalence change that the utility model claim is done, still belong to protection domain of the present utility model.
