Abstract
The utility model discloses a small-hole punching center punch breaking-preventing die for punching products with the punch hole diameter smaller than the thickness of the materials, two sections of reinforcing are arranged in a center punch, two layers of inserts are arranged in a middle template, and the two layers of inserts in the middle template play a role of alignment guiding, the first insert in the middle template guides alignment of the first section of reinforcing of the center punch, the second insert in the middle template guides alignment of the second section of reinforcing of the center punch, the first insert in the middle template and the second insert in the middle template are hung firmly through the forked tail shape, the first insert in the middle template and the second insert in the middle template are prevented from falling into the die, and the die is prevented from being broken. The small-hole punching center punch breaking-preventing die is very good in structure, the strength of the center punch is protected, cost is low, dismounting and mounting are convenient, and applicability is high.
Description
Technical field
The utility model relates to punching press field, particularly relates to the anti-breaking mould of a kind of aperture punching press punching pin.
Background technology
When product has aperture punching press, in prior art, punching pin is done a joint and is strengthened, directly often can only correcting one section by middle template, and due to punching stroke relation, the part that punching pin is the thinnest need to be accomplished 8mm left and right, has so all affected greatly the intensity of punching pin, and punching pin phenomenon of rupture often occurs in punching course.
Utility model content
The technical problem that the utility model mainly solves is to provide the anti-breaking mould of a kind of aperture punching press punching pin, and it is with low cost, easy accessibility, and applicability is strong.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of aperture punching press punching pin anti-breaking mould, comprise successively from top to bottom: upper bolster, upper die plate, cope match-plate pattern, middle die-cushion plate, middle template, lower bolster, counterdie backing plate and die shoe, described middle template inside be also provided with in first that mould is inserted and second in mould insert, in described first mould insert and second in the axis inserted of mould be positioned at same straight line, in first, mould is inserted and is arranged at the top that in second, mould is inserted, the bottom that in first, mould is inserted is provided with groove, the top that in second, mould is inserted is provided with projection, described groove and protruding position and shape match.
Preferably, the insert groove of bottom of mould is dovetail groove in described first, and the insert projection at top of mould is closely connected with dovetail groove in second, prevents from second that mould is inserted to drop, and breaks mould.
The beneficial effects of the utility model are: the utility model adds two-layer inserting in middle template, and two-layer inserting all played correcting effect, prevent from punching pin phenomenon of rupture occurs in punching course, have protected punching pin, and with low cost, easy accessibility, practicality are stronger.
Accompanying drawing explanation
Fig. 1 is the structural representation of anti-breaking mould one preferred embodiment of the utility model aperture punching press punching pin;
Fig. 2 is the part signal enlarged drawing of A part in Fig. 1;
In accompanying drawing, the mark of each parts is as follows: 1, upper bolster, and mould is inserted in 2, upper die plate, 3, cope match-plate pattern, 4, middle die-cushion plate, 5, middle template, 6, lower bolster, 7, counterdie backing plate, 8, die shoe, 9, punching pin, 10, first, and mould is inserted in 11, second.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises:
The anti-breaking mould of a kind of aperture punching press punching pin, comprise successively from top to bottom: upper bolster 1, upper die plate 2, cope match-plate pattern 3, middle die-cushion plate 4, middle template 5, lower bolster 6, counterdie backing plate 7 and die shoe 8, described middle template 4 inside are also provided with in first the mould mould in 10 and second of inserting and insert 11, in described first, mould insert 11 the axis of mould in 10 and second of inserting is positioned at same straight line, in first, mould is inserted and 10 is arranged at insert 11 top of mould in second, in first, insert 10 bottom of mould is provided with groove, in second, insert 11 top of mould is provided with projection, described groove and protruding position and shape match.
As shown in Figure 1: punching pin 9 is done two joints and strengthened, in middle template 5, do two-layer inserting, two-layer middle mould is inserted and is all played correcting effect, in first, the insert first paragraph of 10 correcting punching pines 9 of mould is strengthened, in second, the insert second segment of 11 correcting punching pines 9 of mould is strengthened, in second, the mould mould of inserting in 11 use swallowtail shapes and first is inserted and 10 is firmly linked with, prevent from falling into and in mould, break mould, punching pin 9 is followed upper mould and is partly moved up and down, when punching pin 9 moves downward in process, first in first, the insert first paragraph of 10 correcting punching pines 9 of mould is strengthened, continue again to move downward, in second, the insert second segment of 11 correcting punching pines 9 of mould is strengthened, until material is worn in punching pin 9 punchings, prevent from occurring punching pin phenomenon of rupture in punching course, protected punching pin 9.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
