Abstract

The utility model discloses a kind of shaving die for preventing from bursting apart, including part of the upper die and part of the lower die, part of the upper die includes cope plate and the cutter being fixedly connected with cope plate lower end;Part of the lower die includes lower template and the support block being fixedly connected with lower template upper end, and the top of cutter is upper wide lower sharp spine shape.A kind of shaving die for preventing from bursting apart of the utility model, pass through the improvement to cutter, the point of a knife in trimming is enabled to be easier to contact and stretch into the cut edge of product, quickly cut-out cutting edge contact with product edge, so that to collapse material less for the product shearing of production, the defects of reducing product face, yield rate is added, the outward appearance and mechanical performance of product are improved, and extends the mold use life-span.

Description

A kind of shaving die for preventing from bursting apart
Technical field
It the utility model is related to shaving die, and in particular to a kind of shaving die for preventing from bursting apart.
Background technology
In machinery production manufacturing process, many times need to carry out a systems such as punching press, trimming to the product of the manufacturing Column processing is processed.Existing shaving die upper plate a, cutter b, support block c and lower shoe d as shown in figure 1, be made up of, the mould Tool knife edge contact product, is cut during trimming is carried out to product e to product, but because the fixture edge of a knife is generous, to production When product are cut, easily cause by product cut it is bad, cut and collapse, have a strong impact on the outward appearance and mechanical performance of product, and as mould uses Frequently, die life and product quality are had a strong impact on.
Utility model content
The purpose of this utility model is to provide a kind of shaving die for preventing from bursting apart, and solution is entered to product in the prior art Row cut to caused by product when cutting it is bad, cut the problem of collapsing, to improve the outward appearance of product and mechanical performance, and extend making for mould Use the life-span.
To achieve the above object, the utility model uses following technical scheme:A kind of shaving die for preventing from bursting apart, including Part of the upper die and part of the lower die, part of the upper die include cope plate and the cutter being fixedly connected with cope plate lower end;Lower mold portion subpackage Lower template and the support block being fixedly connected with lower template upper end are included, the top of cutter is upper wide lower sharp spine shape.
In above structure, the top of cutter is the spine shape of upper wide lower point, and in trimming, point of a knife can be easier to contact and stretch Enter the cut edge of product so that quickly cut, quickly cut off cutting edge contact with product edge so that the production of production It is less that material is collapsed in product shearing, the defects of reducing product face, adds yield rate.
Cope plate is fixedly connected with cutter by screw.
Lower template is fixedly connected with support block by screw.
Top accounts for 1/3rd of cutter.
With part of the lower die when cutting, there is interocclusal clearance in cutter with support block for part of the upper die.Punching speed is ensure that, is made Product shearing is smooth.
In summary, a kind of shaving die for preventing from bursting apart, passes through the improvement to cutter so that in trimming, point of a knife can be more Easily contact and stretch into the cut edge of product, quickly cut off cutting edge contact with product edge so that the product of production It is less that material is collapsed in shearing, the defects of reducing product face, adds yield rate, improves the outward appearance and mechanical performance of product, and prolong The mold use life-span is grown.
Brief description of the drawings
The utility model is further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is the schematic diagram of existing shaving die cropping of products;
Fig. 2 is a kind of schematic diagram for the shaving die cropping of products for preventing from bursting apart of the utility model.
In figure, 1. cope plates, 2. cutters, 3. support blocks, 4. lower templates, 5. products;
21. top.
Embodiment
As shown in Fig. 2 a kind of shaving die for preventing from bursting apart of the utility model, a kind of shaving die for preventing from bursting apart, bag Part of the upper die and part of the lower die are included, part of the upper die includes cope plate 1 and the cutter 2 being fixedly connected with the lower end of cope plate 1;Lower mold portion Dividing includes lower template 4 and the support block 3 being fixedly connected with the upper end of lower template 4, and the top 21 of cutter 2 is upper wide lower sharp spine Shape.
Cope plate 1 is fixedly connected with cutter 2 by screw.
Lower template 4 is fixedly connected with support block 3 by screw.
Top 21 accounts for 1/3rd of cutter 2.
With part of the lower die when cutting, there is interocclusal clearance in cutter 2 with support block 3 for part of the upper die.
A kind of shaving die for preventing from bursting apart of the utility model uses process:Product 5 is positioned in lower template 4 first, And the cutting edge of product 5 is located close to support block 3, then mould carries out punching by press to product so that the point of cutter 2 The contact product cutting edge of top 21 of shape is pierced, the top 21 of spine shape can be easier to contact and stretch into cutting for product in trimming Cut edge edge, quickly cut off cutting edge contact with product edge so that production product shearing collapse expect it is less, reduce product The defects of face, yield rate is added, improve the outward appearance and mechanical performance of product, and extend the mold use life-span.
