Description
Technical field
The utility model is related to a kind of new mould for tearing.
Background technology
Generally, can be on the bottom surface of sheet material in hole after punching on sheet material with punching die in common punch press
There is burr in edge, therefore, also to there is debarring process after punching.The debarring process of prior art is more, most of to be
Sanding and polishing or electrochemical deburring.The method that also improvement mould carries out deburring punching with mould, but this method needs will punching
The sheet material in hole stands up 180 degree and carries out second of punching, requires high to accuracy of alignment, common punch press is difficult to, and to be carried out
Punching and deburring two procedures.Or have the method that positive deburring is carried out on punching die, Mold Making complexity and bottom surface
Burr can not be removed, and this mould needs to use on special punch press, and for example Publication No. 201220027060.9 is special
Profit application, i.e., using positive deburring method, it is necessary in deburring mould and under spherical punch-pin cooperation come extrusion orifice, then
Will also be by shaping terrace die come shaping, the punching die structure is complicated.
Utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of new mould for tearing,
Flash removed can be removed while tearing.
In order to achieve the above objects and other related objects, the utility model provides a kind of new mould for tearing, including upper mould
It is provided with below seat, die shoe, the upper bolster above cope plate, the die shoe and is provided with lower template, the cope plate is provided with
Drift, the lower template is provided with cavity plate, and the cavity plate is located at the underface of the drift, and the drift includes spine face peace
Table top, the flat surface and the plane-parallel, the angle between the flat surface and the spine face is 30-45 °, described
Cavity plate be provided with the punch shape identical concave die cavity, between the concave die cavity and the drift be provided with gap.
Preferably, the gap size between the concave die cavity and the drift is the 1.5% of product thickness to be punched.
Preferably, the angle between the spine face of the drift and the flat surface is 40 °.
Preferably, the lower section of the cavity plate is provided with nitrogen spring.
Preferably, the drift below the cope plate is 2.
50 ° of the nose of punch single sided taper of conventional mould for tearing structure, is directly punctured, nose of punch cusp is not wear-resisting, is held
It is easy to wear and burst apart cause during produce burr, originally tearing drift and cavity plate gap is designed according to normal punching, is passed through
Blade clearance will be changed and expect that thick 5% changes 1.5% to material thickness by normal blade clearance before, make the reduction of the tear-strap after tearing,
So as to change the presence of burr significantly, then the wedge angle drift originally designed is changed to carry platform-type buffering step, allows drift bottom
The flat surface contact product surface in portion is torn, and can remove flash removed, so as to greatly promote the Dies ' Blanking life-span.
In summary, a kind of new mould for tearing of the present utility model has the advantages that：The mould structure is simple,
Small volume, simple to operate, ground area is small, and practicality is very strong.The problem of original product produces burr after tearing is can solve the problem that, and
It can improve the mold use life-span, improve product quality, be particularly suitable for use in tearing material thickness more than 1.5mm product.

Embodiment
Embodiment of the present utility model is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages of the present utility model and effect easily.
Fig. 1 is referred to Fig. 2.It should be clear that structure, ratio, size depicted in this specification institute accompanying drawings etc., is only used to
Coordinate the content disclosed in specification, so that those skilled in the art is understood with reading, be not limited to the utility model
Enforceable qualifications, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or size
Adjustment, in the case where not influenceing the utility model effect that can be generated and the purpose that can reach, all should still fall in the utility model
Disclosed technology contents are obtained in the range of covering.Meanwhile, in this specification it is cited as " on ", " under ", " left side ",
The term on " right side ", " centre " and " one " etc., is merely convenient to understanding for narration, and it is enforceable to be not used to restriction the utility model
Scope, being altered or modified for its relativeness is enforceable when being also considered as the utility model under without essence change technology contents
Category.
As shown in Figure 1 to Figure 2, the utility model provides a kind of new mould for tearing, including upper bolster 1, die shoe 4, institute
State the lower section of upper bolster 1 and be provided with cope plate 2, the top of die shoe 4 is provided with lower template 3, and the cope plate 2 is provided with drift 6, institute
Lower template 3 is stated provided with cavity plate 7, the cavity plate 7 is located at the underface of the drift 6, the drift 6 includes the peace of spine face 62
