Abstract
The utility model discloses a third beam stretching piece of an automobile top cover. The stretching piece can reduce the friction force between the stretching piece and a stretching mold. The third beam stretching piece of the automobile top cover comprises a stretching body. A stretching chamfer is arranged on the stretching body. A drawing face is arranged at the upper portion of the side face of the stretching body. The stretching chamfer is located between the stretching face and the upper surface of the stretching body. The stretching chamber has the effective radius R, and the R is 10mm. By the adoption of the deep-drawing stretching piece, due to the fact that the effective radius R of the stretching chamfer is increased, the friction force between the stretching body and the stretching mold in the drawing process is reduced, materials run more smoothly, internal injuries caused by excessive stretching at the stretching chamfer 2 are avoided, and the stability of the stretching piece is improved.
Description
Technical field
The utility model relates to a kind of car body part, particularly relates to a kind of automobile top-cap the 3rd crossbeam tensioning member.
Background technology
Known: automobile top-cap the 3rd crossbeam is a support component of automobile, in automobile top-cap the 3rd crossbeam production process, the radius R (5mm) of the deep-draw chamfering having due to top cover the 3rd crossbeam tensioning member is too small, friction force between tensioning member and diel is larger, therefore cause automobile top-cap the 3rd crossbeam of producing large in its deep-draw chamfering position plate amount of tension, occur the situation of internal injury.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of automobile top-cap the 3rd crossbeam tensioning member that can reduce friction force between tensioning member and diel.
The utility model solves the technical scheme that its technical matters adopts: automobile top-cap the 3rd crossbeam tensioning member, comprise extrusion, and in described extrusion, be provided with stretching chamfering; The top of described extrusion side is provided with the face of drawing, and stretching chamfering is being drawn between the upper surface that face and extrusion have; Described stretching chamfering has effective radius R, and R is 10mm.
Preferably, described extrusion adopts DC04 cold-reduced sheet material to make.
The beneficial effects of the utility model: automobile top-cap described in the utility model the 3rd crossbeam tensioning member, increased the stretching chamfering in extrusion, reduced the friction force between tensioning member and diel, thereby can be so that tensioning member be walked to expect smooth and easy in drawing process, avoid causing internal injury at stretching chamfering place stretching transition, improve the stability of product part.
Accompanying drawing explanation
Fig. 1 is the structure diagram of automobile top-cap of the present utility model the 3rd crossbeam tensioning member;
In figure, indicate: 1-extrusion, 2-stretching chamfering, 3-draws face, 4-upper surface.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, automobile top-cap the 3rd crossbeam tensioning member, comprises extrusion 1, in described extrusion 1, is provided with stretching chamfering 2; The top of described extrusion 1 side is provided with the face of drawing 3, and stretching chamfering 2 is being drawn between the upper surface 4 that face 3 and extrusion 1 have; Described stretching chamfering 2 has effective radius R, and R is 10mm; Described stretching chamfering 2 is arranged between the face of drawing 3 and the upper surface 4 of extrusion 1, is usually called as position, R angle in the industry.
Above-mentioned automobile top-cap the 3rd crossbeam tensioning member is different below comparing from existing the 3rd crossbeam tensioning member and existing:
The effective radius that the stretching chamfering 2 arranging on existing the 3rd crossbeam tensioning member has is 5mm, above-mentioned automobile top-cap the 3rd crossbeam tensioning member, and the effective radius that the stretching chamfering 2 arranging in extrusion 1 has is 10mm.Owing to having increased the effective radius of stretching chamfering 2, therefore make the friction force between extrusion 1 and diel in drawing process reduce, walk material more smooth and easy, avoid causing internal injury at stretching chamfering 2 place's stretching transitions, improved the stability of product; After changing stretching chamfering 2, in extrusion 1, level can not change simultaneously, and can be more even by the wall thickness of the smooth and easy plate of plate charging meeting after optimizing, and is conducive to increase the intensity of blanked part.
In order to make to draw body 1 to there is stronger toughness, guarantee the stability of extrusion 1 in drawing process, described extrusion 1 adopts DC04 cold-reduced sheet material to make.Selecting of machining sheet, select to be suitable for drawing the DC04 cold-reduced sheet material of use, due to DC04 cold-reduced sheet, to rush dark property good, is not prone to internal injury, and feeding is smooth and easy, thereby actv. has guaranteed the stability of the product of automobile top-cap the 3rd crossbeam tensioning member.
Embodiment mono-
As shown in Figure 1, automobile top-cap the 3rd crossbeam tensioning member, comprises extrusion 1, in described extrusion 1, is provided with stretching chamfering 2; Described stretching chamfering 2 has effective radius R, and R is 10mm, and described stretching chamfering 2 is arranged between the face of drawing 3 and the upper surface of extrusion 1.
The step of manufacturing top cover the 3rd crossbeam by above-mentioned automobile top-cap the 3rd crossbeam tensioning member is as follows:
1, modified in the stretching angle of the Extrude Face of former diel, the chamfering of convex concave mould correspondence position synchronously strengthens, and stretching angle effective radius increases to 10mm by 5mm;
2, at the R angle place of diel, proportionally increase the size at R angle, and in material, to use cr12mov, described cr12mov be a kind of common mould manufactured materials, can in mold materials selection standard, find.Processing improves later the degree of finish at place, R angle again with oil abrasion, what actv. improved place, product R angle walks to expect smooth and easy, and keeps its stability.
3, automobile top-cap the 3rd crossbeam tensioning member is arranged in diel, stretches.
Owing to having increased the effective radius of stretching chamfering 2, therefore make the friction force between extrusion 1 and diel in drawing process reduce, walk material more smooth and easy, avoid causing internal injury at stretching chamfering 2 place's stretching transitions, thereby improved the stability of product.
