Abstract
The utility model relates to a car body steel metal which comprises a steel metal main body. A skirt edge structure is arranged on the periphery of the steel metal main body, wherein the skirt edge structure is used for preventing the steel metal main body from wrinkling when the steel metal main body is molded. An edgefold is arranged on the opening of the steel metal main body, and the skirt edge structure is close to the edgefold. The car body steel metal has the advantages that wrinkles of the steel metal main body is smoothened when the steel metal main body is molded due to the skirt edge structure added to the periphery of the steel metal main body, the quality problems caused by the wrinkles of the steel metal main body when the steel metal main body is molded is solved, service life of the steel metal is increased and meanwhile the manufacturability and the functionality of the steel metal is guaranteed.
Description
Technical field
The utility model relates to the vehicle technology field, relates in particular to a kind of vehicle body sheet metal.
Background technology
In the manufacturing process in enormous quantities of automobile, there is contradiction between the functional and manufacturability of part, need technical personnel constantly to go to coordinate to satisfy the requirement of two aspects.Usually adopt the more cold drawing forming mode of restriction owing to bear the sheet metal part of car load carrying and safe important task again, so this contradiction is more outstanding on car body stamping part.In order to improve the support strength of sheet metal part, the box-like that is shaped as sealing or half box-like structure (as shown in Figure 1) of a lot of panel beatings in the automobile, preventing at present that this box-like class formation wrinkling mode in shaping from mostly being transform many flangings as from soldering part, and can reduce the intensity of part itself and increase Welding Technology and Equipment one like this, head it off in the situation of proof strength how, structure design personnel and Sheet Metal Forming Technology personnel are puzzling always.
The utility model content
In order to solve the problems of the technologies described above, it is a kind of with the skirt border structure vehicle body sheet metal that the utility model provides, and guarantees simultaneously the manufacturability of part and functional.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of vehicle body sheet metal, comprise the panel beating main body, the edge of described panel beating main body is provided be used to preventing described panel beating main body wrinkling skirt border structure when the moulding, the opening part of described panel beating main body is provided with flanging, and described skirt border structure is near described flanging.
Further, the structure of described panel beating main body is case type structures.
Further, be provided with described skirt border structure between the adjacent described flanging.
Further, described skirt border structure is from the outward extending arc-shaped curved surface structure of described panel beating body rim.
The beneficial effects of the utility model are: the edge in described panel beating main body increases skirt border structure, be beneficial to the suction wrinkle of panel beating main body when moulding, solution wrinkling quality problems that cause during because of the moulding of panel beating main body increase service life of panel beating, guarantee simultaneously the manufacturability of panel beating and functional.
Description of drawings
Fig. 1 represents prior art sheet metal structural scheme drawing;
Fig. 2 represents the utility model sheet metal structural scheme drawing.
The specific embodiment
Below in conjunction with accompanying drawing the utility model structure and principle are elaborated, illustrated embodiment only is used for explaining the utility model, is not to limit protection domain of the present utility model with this.
As shown in Figure 1; in the prior art; vehicle body sheet metal comprises the panel beating main body 1 of case type structures; edge at the opening part of panel beating main body 1 is provided with flanging 3; because the line length of box-like structure panel beating main body 1 opening part is sharply dwindled when moulding, will inevitably cause the boundary part wrinkling, this wrinkling rate that thickens usually can be very high; mould drops to after bottom dead centre and also can not smooth away wrinkles, but forms folded dead situation.The rate that thickens in the relevant issues zones (zone between the adjacent flanging 3) after panel beating main body 1 is shaped is about 20%-40%, and such rate that thickens can cause quality problem in actual production.
In order to address this problem, present embodiment provides a kind of vehicle body sheet metal, and as shown in Figure 2, the present embodiment vehicle body sheet metal comprises case type structures panel beating main body 1, and the edge of described panel beating main body 1 is provided be used to preventing described panel beating main body 1 wrinkling skirt border structure 2 when the moulding.
Concrete, the opening part of described panel beating main body 1 is provided with flanging 3, and described skirt border structure 2 is arranged on the position near described flanging 3.
In the present embodiment, be provided with described skirt border structure 2 between the adjacent described flanging 3, and this skirt border structure 2 is positioned at described panel beating main body 1 opening part, connection, adjacent two side.
In the present embodiment, described skirt border structure 2 is the arc-shaped curved surface structure from the outward extending rounding off in described panel beating main body 1 edge.
Opening part in box-like structure panel beating main body 1, just increase the skirt border structure 2 of two parts in the sheet metal designing stage, namely between adjacent described flanging 3, described skirt border structure 2 is set, in the metal plate forming process, this skirt border structure 2 can guide to unnecessary blank in the described skirt border structure 2, thereby has guaranteed quality and the integrally-built intensity of mating edge.
Increased after the described skirt border structure 2, balance the line length of box-like structure panel beating main body 1 opening part in forming process, sharply reduce the problem brought, so that the reduction at panel beating main body 1 opening part edge declines to a great extent to 5%-10%, the zone at described skirt border structure 2 places is the sensitivity volume of wrinkling folded material, adopts this skirt border structure 2 this problem can be solved.
The above is the utility model preferred embodiment; should be pointed out that to those skilled in the art, under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as the utility model protection domain.
