Abstract

The utility model relates to a kind of punching die, belongs to mechanical field.A kind of punching die, comprise drift and die sleeve, described drift comprises the first connecting portion, the second connecting portion and the 3rd connecting portion that connect from the bottom to top, and the radius that the radius of described 3rd connecting portion is greater than the second connecting portion is greater than the radius of the first connecting portion.Punching die described in the utility model, structure is simple, applied widely, can solve the technical problem that punching die of the prior art is unfavorable for carrying out for the sheet material that hardness is larger punching, it is a little longer that the punching die of punching die described in the utility model also has shelf life.

Description

A kind of punching die
Technical field
The utility model relates to a kind of punching die, belongs to mechanical field.
Background technology
Punching die, as the one of the high efficiency tool of production, is use in industrial production very extensively and important technological equipment.Adopt punching die article of manufacture and part, there is production efficiency high, the large batch of production of high speed can be realized.Design that the punching die held water can not only improve the quality of products, productivity ratio, service life, product economy benefit can also be improved.In conventional art, the drift of punching die, is generally column structure, punching under the effect of outside punch press.But for the larger specific sheet material of some hardness, there is the situation of broken sheet material difficulty in the drift of column structure, punching easily damages sheet material by force, and shorten the mold use life-span.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of punching die, and this punching die can solve the technical problem that traditional punching die easily damages sheet material.
The technical solution of the utility model is: a kind of punching die, comprise drift and die sleeve, described drift comprises the first connecting portion, the second connecting portion and the 3rd connecting portion that connect from the bottom to top, and the radius that the radius of described 3rd connecting portion is greater than the second connecting portion is greater than the radius of the first connecting portion.
Drift is designed to the stepped construction that radius increases from the bottom to top successively by the utility model, when punching, first connecting portion minimum by radius first wears out the sheet material treating punching, plate surface is made to produce the crackle of certain area, then the second connecting portion is worn out crackle further and is expanded in hole, stablizes the aperture in rushed hole finally by the 3rd connecting portion.There is the technical problem of broken sheet material difficulty in the drift that can solve traditional column structure.
Further, described first connecting portion is connected by chamfering with the second connecting portion.
Further, described second connecting portion is connected by chamfering with the 3rd connecting portion.
Chamfering syndeton can when colliding dissipation of ferees to a certain extent, extend the service life of drift.
Further, described first connecting portion is conical structure.
Further, the ratio of the radius of the radius of described first connecting portion, the radius of the second connecting portion and the 3rd connecting portion is 1:2:4.
Further, the height of the second connecting portion is 2 times of the first connecting portion height.
Punching die described in the utility model, structure is simple, applied widely, can solve the technical problem that punching die of the prior art is unfavorable for carrying out for the sheet material that hardness is larger punching, it is a little longer that the punching die of punching die described in the utility model also has shelf life.
Accompanying drawing explanation
Fig. 1 is the first preferred embodiment structural representation of the drift of punching die described in the utility model.
Fig. 2 is the second preferred embodiment structural representation of the drift of punching die described in the utility model.
Fig. 3 is the A portion partial enlarged drawing of Fig. 1.
Detailed description of the invention
Punching die described in the utility model comprises drift and overlaps with punching.
Please refer to Fig. 1, Fig. 1 is the structural representation of the drift of punching die described in the utility model.
Described drift comprises the first connecting portion 1, second connecting portion 2 and the 3rd connecting portion 3 that connect from the bottom to top, described first connecting portion 1, second connecting portion 2 and the 3rd connecting portion 3 are column structure, and the radius that the radius of described 3rd connecting portion 3 is greater than the second connecting portion 2 is greater than the radius of the first connecting portion 1.
As a kind of preferred embodiment of the present embodiment, from punching angle easily, please refer to Fig. 2, described first connecting portion 1 is conical structure.
Drift is designed to the stepped construction that radius increases from the bottom to top successively by the utility model, when punching, first connecting portion 1 minimum by radius first wears out the sheet material treating punching, plate surface is made to produce the crackle of certain area, then the second connecting portion 2 is worn out crackle further and is expanded in hole, finally by the aperture in the 3rd stable hole rushed of connecting portion 3.
In actual use, described first connect, 1 and second connecting portion 2 owing to colliding sheet material for a long time, be that drift easily produces deformation, affect the service life of drift.For solving this technical problem, please refer to Fig. 3, described first connecting portion 1 is connected by chamfering with the second connecting portion 2.Chamfering syndeton can when colliding dissipation of ferees to a certain extent, extend the service life of drift.
In like manner, described second connects, and 2 are connected by chamfering with the 3rd connecting portion 3.
As a kind of preferred embodiment of the present embodiment, the ratio of the radius of the radius of described first connecting portion 1, the radius of the second connecting portion 2 and the 3rd connecting portion 3 is 1:2:4.The height of described second connecting portion 2 is more than 2 times of the first connecting portion 1 height.
Punching die described in the utility model, structure is simple, applied widely, columniform drift traditional in prior art can be solved, be unfavorable for the technical problem of carrying out punching for the sheet material that hardness is larger, it is a little longer that the punching die of punching die described in the utility model also has shelf life.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
