Abstract

The utility model provides an arc surface bending mould which comprises an upper mould base and a lower mould base, wherein the upper mould base is provided with a bending punch, the lower mould base is provided with a bending concave mould matched with the bending punch, at least one corner of the bending punch is a fillet, and an arc surface of the fillet is provided with triangular reinforced ribs. Triangular ribs are formed on the arc surface of a product during a punching process, and therefore own stress of materials is damaged and warping of the product due to bending is avoided.

Description

A kind of arc surface Bending Mould

Technical field

The utility model relates to a kind of mould, is specifically related to a kind of arc surface bending jig of product.

Background technology

When product is carried out the bending operation, tend to because bending has destroyed the stress equilibrium of material, and cause product to produce warpage or out-of-flatness, cause defective products, bring loss to factory.

The utility model content

For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of bending jig, improves warpage or out-of-flatness that product produces when carrying out the bending operation.

For achieving the above object, the technical solution of the utility model is as follows: a kind of arc surface Bending Mould, comprise upper bolster and die shoe, described upper bolster is provided with Bending punch, described die shoe is provided with the bending female die that is complementary with described Bending punch, it is fillet that described Bending punch has an angle at least, and the arc surface of described fillet is provided with the triangle reinforcement.

Preferably, described triangle reinforcement arranges along the punching direction straight line of described fillet.

Preferably, described triangle reinforcement quantity is at least three.

Preferably, described triangle reinforcement evenly distributes along described fillet.

Preferably, the drift angle angle of described triangle reinforcement is 70-110 °.

Preferably, the height of described triangle reinforcement is the thick 0.15-0.3 of punching material times.

Adopt the beneficial effect of above technical scheme to be: in the cambered surface punching process of product, the triangle reinforcement on Bending punch forms vee at the product arc surface, has cut off the stress of material itself, avoids producing warpage because bending causes product.

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

The utility model provides a kind of arc surface Bending Mould, comprise upper bolster and die shoe, described upper bolster is provided with Bending punch, described die shoe is provided with the bending female die that is complementary with described Bending punch, it is fillet that described Bending punch has an angle at least, and the arc surface of described fillet is provided with the triangle reinforcement.

Embodiment 1:

As shown in Figure 1, the arc surface Bending Mould comprises upper bolster 1 and die shoe 6, upper bolster 1 is provided with Bending punch 2, die shoe 6 is provided with the bending female die 4 that is complementary with Bending punch 2, also be provided with buoyant plate 5 on die shoe, when the punching product, the descending product that touches of Bending punch 2, product is pressed in continues together descendingly on buoyant plate 5, be pressed into bending female die 4.As shown in Figure 2, an angle of Bending punch is set to fillet, is provided with triangle reinforcement 21 on the arc surface of fillet.Triangle reinforcement 21 arranges along the punching direction straight line of fillet.As shown in Figure 3, the triangle reinforcement is four along the quantity of fillet setting, lays respectively at 1/3 place of fillet, 2/3 place of fillet and the place, two point of contacts of fillet.As shown in Figure 4, the material of product is thick when being 1.2mm,, the drift angle of triangle reinforcement is 90 °, the height of triangle reinforcement is thick 0.17 times of product material, is 0.2mm.

Embodiment 2:

All the other are identical with embodiment 1, and difference is, the triangle reinforcement is three along the quantity of fillet setting, lay respectively at 1/2 place of fillet and the place, two point of contacts of fillet.

Embodiment 3:

All the other are identical with embodiment 1, and difference is, the material of product is thick is 2 mm, and the drift angle of triangle reinforcement is 80 °, and the height of triangle reinforcement is thick 0.2 0 times of product material, is 0.4mm.

Embodiment 4:

All the other are identical with embodiment 1, and difference is, the material of product is thick is 0.8mm, and the drift angle of triangle reinforcement is 100 °, and the height of triangle reinforcement is thick 0.2 times of product material, is 0.16mm.

Embodiment 5:

All the other are identical with embodiment 1, difference is, the material of product is thick is 2 mm, the triangle reinforcement is 5 along the quantity of fillet setting, lay respectively at 1/4 place of fillet, 1/2 place of fillet, 3/4 place of fillet and the place, two point of contacts of fillet, the drift angle of triangle reinforcement is 80 °, and the height of triangle reinforcement is thick 0.20 times of product material, is 0.4mm.

In the above-described embodiments, the number of the triangle muscle that arranges on the arc surface at drift fillet place is that the fillet size according to required punching arranges, and fillet is larger, need increase the number that arranges of triangle muscle, does not limit herein.

In the above-described embodiments, the fillet of drift can require to be made as one or more according to the punching of product, at least three triangle muscle are set on fillet as required.

Adopt above technical scheme, in the arc surface punching process of product, the triangle reinforcement on Bending punch forms vee at the product arc surface, has cut off the stress of material itself, avoid producing warpage or out-of-flatness because bending causes product, reduce the generation of defective products.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
