Abstract
The utility model discloses a kind of metal stamping die edge of a knife corner structure, comprise and support the upper padding plate of material stripping drift and the stripper plate of correcting material stripping punching pin, it is characterized in that: punching pin fixed by train wheel bridge, stripper plate correcting punching pin with push down raw material, material stripping punching pin and the counterdie edge of a knife is made to enter the cooperation position zero deflection of block, again the counterdie edge of a knife is entered block corner gap to strengthen, reduce the friction to punching pin, improve the service life of punching pin.The utility model advantage is compared with prior art: the utility model structure is very simple, and operation is also very convenient, effectively raise material stripping punching pin service life and after preventing metal material product cutting from completing the scrap of corner produce.
Description
Technical field
The utility model relates to a kind of metal stamping die edge of a knife corner structure, belongs to metal stamping techniques field.
Background technology
Traditional stripping technology, the corner of product all sets identical with the straight flat blade clearance located, and the wearing and tearing of material stripping punching pin corner are very serious, and in production in the near future, corner easily produces fines to this technique, and cause product to weigh wounded, scratch etc. are bad.
Utility model content
The utility model is to solve above-mentioned deficiency, provides a kind of structure simple, easy to operate, can effectively extend or prevent the metal material product cutting structure that tiny scrap produces after having cut.
Above-mentioned purpose of the present utility model is realized by following technical scheme: a kind of metal stamping die edge of a knife corner structure, comprise: upper padding plate, train wheel bridge, stripper plate, material stripping drift, the counterdie edge of a knife enter block, it is characterized in that: described upper padding plate is connected with slider of punch, after described train wheel bridge is fixing by material stripping drift, be connected with upper padding plate, it is matched in clearance that the described counterdie edge of a knife enters between the edge of a knife of block and material stripping drift, and the gap, corner of the edge of a knife and material stripping drift that the counterdie edge of a knife enters block is 1.3 ~ 2 times of straight Ping Chu gap.
The surface roughness of described material stripping drift is within 0.008mm;
The hardness of described material stripping drift material need be greater than more than HRC62 degree;
Operation principle of the present utility model is: the utility model first utilizes stripper plate and lower bolster to be pushed down by material, by material stripping punching pin, unnecessary raw material are excised, in counterdie edge of a knife corner, gap is strengthened, the material elastic deformation time is before separation lengthened, reduce reaction force to punching pin, improve punching pin service life.
The utility model advantage is compared with prior art: the utility model structure is very simple, and operation is also very convenient, in effective service life of improving punching pin, prevents the fines of cutting corners.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing, 1-upper padding plate; 2-train wheel bridge; 3-stripper plate; 4-material stripping drift; 5-material; 6-counterdie edge of a knife enters block; 7-waste material.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of metal stamping die edge of a knife corner design, comprise upper padding plate 1, train wheel bridge 2, stripper plate 3, material stripping drift 4, the counterdie edge of a knife enter block 6, described upper padding plate 1 is connected with slider of punch, described train wheel bridge 2 by after fixing for material stripping drift 4,
Train wheel bridge 2 is fixed on slider of punch by upper padding plate 1, it is made to drive material stripping punching pin 4 to do upper and lower back and forth movement by slider of punch, stripper plate 3 had not only been pushed down by material stripping punching pin 4 correcting but also by material 5, material stripping punching pin 4 and the counterdie edge of a knife is made to enter block 6 matched in clearance, entering gap, block 6 corner by strengthening the counterdie edge of a knife, improving the service life of material stripping punching pin 4, preventing corner scrap from producing, described material stripping drift and the counterdie edge of a knife need matched in clearance, and the gap of corner is than directly putting down the gap at place at 1.3 ~ 2 times.
As preferred version of the present utility model, the surface roughness of described material stripping drift 4 is within 0.008mm; The material hardness of described material stripping drift 4 need be greater than more than HRC62 degree.
The course of work of the present utility model is: first utilize stripper plate 3 and lower bolster 4 to push down fixing by material 5, by material stripping punching pin 4, excess waste 7 is excised, in the counterdie edge of a knife 6 corner, gap is strengthened, the elastic deformation time lengthens before separation to make material 5, reduce reaction force to material stripping punching pin 4, improve material stripping drift service life.
It is last it is noted that above-described embodiment is only for the utility model example is clearly described; and the restriction not to embodiment; for those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here exhaustive without the need to also giving all embodiments, and thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
