Abstract

The utility model relates to a drawing die blank holder group of inserting. The utility model discloses in aiming at solving prior art the stamping process, the blank holder is inserted and produce the displacement under the effect of the finished piece power of taking shape, produces the problem that the finished piece has the drawing stamp thereupon. The utility model discloses suit with the blank holder shape, including the inserting of some, contact the facial features between inserting and be cyclic annular the distribution to the center of blank holder, and disperse to the outside of blank holder. The utility model has the advantages of to insert produce the auto -lock in the atress orientation, and manufacturing deviation that the removal having avoided inserting brought has also protected and insert simultaneously, lengthens its life.

Description

Drawing die blank holder insert group
Technical field
The utility model relates to mould applications, particularly a kind of drawing die blank holder insert group.
Background technology
Due to the requirement of automotive light weight technology, automobile panel high-strength plate material gets more and more, and concerning mould drawing operation, only has the material good with anti-wear performance, hardness is high to extend die life.Therefore high-strength plate drawing die general work face all adopts Cr12MoV insert, and matrix is cast iron HT300.
But in actual production, especially in punching course, after blank holder binder surface insert, the Impact direction due to material is inside, the displacement of cutter block and product can be caused to draw trace, affect service life and the accuracy of manufacture.
Summary of the invention
The purpose of this utility model is exactly to solve in prior art punching course, and blank holder insert is under the effect of product plastic force, and produce displacement, can produce product has the problem of drawing trace.
Concrete scheme of the present utility model is:
A kind of drawing die blank holder insert group, adapt with blank holder shape, comprise the insert of some, described insert Contact face distributes in the form of a ring relative to the center of blank holder, and disperses to the outside of blank holder.
It is 3 ~ 5 degree relative to product flow direction angle between the both sides contact surface of insert.The width of insert is 200 ~ 300mm.
The beneficial effects of the utility model are:
Insert produces self-locking at Impact direction, the manufacture deviation that the movement avoiding insert brings, and also protects insert simultaneously, extends its service life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model insert partial schematic diagram;
Fig. 3 is that the axle of Fig. 1 surveys direction structure schematic diagram;
Fig. 4 is that the axle of one of insert surveys direction schematic diagram;
Each component names in figure: 1. blank holder body; 2. blank holder insert; 3. location-plate.
Detailed description of the invention
Embodiment: drawing die blank holder insert group, see Fig. 1 to Fig. 4.Adapting with blank holder shape, comprise the insert of some, is 10 pieces in the present embodiment.Insert Contact face distributes in the form of a ring relative to the center of blank holder, and disperses to the outside of blank holder.
It is 3 ~ 5 degree relative to the angle of product flow direction between the both sides contact surface of insert.The width of insert is 200 ~ 300mm.
In the utility model, the shape of insert group and blank holder and upper/lower die adapts, and blank holder insert piece face adopts Eight characters shape, makes cutter block produce self-locking at Impact direction, thus solves cutter block Impact direction displacement problem, also improve product quality.
Finally it should be noted that, above person is only the utility model part embodiment, and is not used to limit the present invention, and according to structure of the present utility model and feature, the modifications person of forming a little, also should be included within the utility model scope.
