Abstract
The utility model discloses a stamping part for a front gate post support of an automobile. The stamping part can avoid internal damage and cracks caused in the stretching process. The stamping part for the front gate post support of the automobile comprises a support body, and a stretching portion is arranged on the support body. A process tank is arranged in the stretching portion. According to the stamping part for the front post support of the automobile, due to the fact that the process tank is arranged in the support body, the drawing force of the deep drawing portion of the front gate post support of the automobile is reduced, board feeding is smoother, and the internal damage and cracks, caused by excessively-large drawing force, to boards are avoided. Product self-strength is improved, and product stability is improved.
Description
Technical field
The utility model relates to a kind of car body part, particularly relates to a kind of automobile front door pillar support blanked part.
Background technology
Known: it is auto body blanked part that automobile front door pillar support blanked part belongs to plate, directly have influence on the intensity of auto body, in the production process of automobile front door pillar support, conventionally adopt product directly to stretch, due to die drawn more complicated, the complicated forming height of tension shape is larger, and easily local elongation is excessive, causes punch-out to have the phenomenon of internal injury and cracking.
Utility model content
Technical problem to be solved in the utility model is to provide a kind ofly can avoid the internal injury that causes in drawing process and the automobile front door pillar support blanked part of cracking.
The utility model solves the technical scheme that its technical matters adopts: automobile front door pillar support blanked part, comprise stake body, and on described stake body, be provided with stretching position; Described stretching is provided with technology groove on position.
Preferably, described technology groove becomes football pitch track type, and described football pitch track type is by the first long limit, the second long limit and the first circular arc, and the second circular arc forms; The described first long limit, the second long limit are rectangle opposite side, described football pitch track type has total length, the described first long limit has length, the radius that described the first circular arc has is identical with the radius that the second circular arc has, described the first circular arc has radius R, and described football pitch track type extends along the vertical direction at stretching position.
Preferably, described stake body adopts B210P1 cold-rolling steel material.
The beneficial effects of the utility model: automobile front door pillar support blanked part described in the utility model by arranging technology groove on stake body, thereby reduce the pulling force at automobile front door pillar support deep-drawing position, it is more smooth and easy that plate is walked material, internal injury and the cracking of having avoided sheet metal stretching excessively to cause.Increase self intensity of product, improved the stability of product.
Accompanying drawing explanation
Fig. 1 is automobile front door pillar support blanked part structure diagram of the present utility model;
Fig. 2 is technology groove structural representation in the utility model automobile front door pillar support blanked part;
In figure, indicate: 1-stake body, 2-stretching position, 3-technology groove, the long limit of 31-first, the long limit of 32-second, 33-the first arc section, 34-the second circular arc, L1-total length, L2-length.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, automobile front door pillar support blanked part, comprises stake body 1, on described stake body 1, is provided with stretching position 2; On the position at described stretching position 2, be provided with technology groove 3.
Because the stretching position of the stake body 1 at automobile front door pillar support blanked part is provided with technology groove 3.Therefore can so that automobile front door pillar support in the process of drawing, stretching position 2 is owing to having lacked the pulling force at technology groove 3 positions, and the pulling force at stretching position 2 reduces, and walks material more smooth and easy, the sheet metal stretching degree at stretching position 2 is more even, avoided the generation of internal injury and cracking after moulding.
The technology groove 3 of above-mentioned shape position 2 pulling force in all directions in drawing process that can make to stretch is less, has guaranteed that charging is smooth and easy, thereby has avoided stretching position 2 to form internal injury or crackings; Wherein total length L 1, length L 2 and radius R can be adjusted according to the size at concrete stretching position 2, make technology groove 3 meet technological requirement.
In order to make automobile front door pillar support blanked part have enough intensity, described stake body 1 adopts B210P1 cold-rolling steel.The model that B210P1 in described B210P1 cold-rolling steel is steel plate, can in the standard of steel plate materials, find, this plate has good punching performance and has high intensity simultaneously, favourable to parts attenuate, and tool dent resistance energy, have outstanding processing characteristics, tensile strength is not easy greatly to occur internal injury cracking phenomena.
Embodiment mono-
As shown in Figure 1, automobile front door pillar support blanked part comprises stake body 1, on described stake body 1, is provided with stretching position 2; On the position at described stretching position 2, be provided with technology groove 3.
As follows in the step that described automobile front door pillar support blanked part is carried out to punching press:
1, first in diel, increase the die cavity of technology groove 3 correspondences and the drift of technology groove 3 correspondences, before stretching, first a technology groove 3 is outputed in the useless position of flitch on stretching position 2 vertical directions of automobile front door pillar support blanked part; 3 one-tenth football pitch track types of described technology groove, described football pitch track type is comprised of first the 31, second long limit 32, long limit and the first circular arc 33, the second circular arcs 34; The described first the 31, second long limit 32, long limit is rectangle opposite side, described football pitch track type has total length L 1, the described first long limit has length L 2, and the radius that described the first circular arc 33 has is identical with the radius that the second circular arc 34 has, and described the first circular arc 33 has radius R; Described football pitch track type extends along the vertical direction at stretching position 2.Adopt the technology groove 3 of above-mentioned shape to compare with the technology groove of rectangle with circular, because slotting length in all directions at stretching position is inconsistent, can adjust according to the characteristic at stretching position 2, thereby the technology groove of above-mentioned shape 3 can make to stretch position 2, the pulling force in all directions in drawing process is less, guaranteed that charging is smooth and easy, thereby avoided stretching position 2 to form internal injury or cracking.
2, then arrange that technology groove 3 is rear carries out moulding punching press to plate, keep original punching press shape.
3, finally because the sheet material position 2 that stretches before making deep-drawing is provided with technology groove 3, therefore stretch position 2 in the process of punching press, the pulling force of technology groove 3 positions reduces, the pulling force at stretching position 2 reduces, walk material more smooth and easy, the sheet metal stretching degree at stretching position is more even, and final molding is the car door pillar support without internal injury and cracking.
