Abstract
The utility model provides a high-intensity front cross member. The arc-shaped front cross member body adopts a single-plate structure which is formed by conducting one-step punch forming on a steel plate; and the front cross member body is 2 to 3 mm in thickness. By adopting the single-plate structure, the overall weight of the front cross member can be reduced effectively so as to realize weight lightening, the production procedure can be simplified, and the production cost and manufacturing cost can be saved.
Description
Technical field
The utility model relates to a kind of auto parts and components, especially relates to a kind of automobile energy-absorbing front cross rail.
Background technology
For the Passenger motor vehicle front cross rail, the double-layer plate structures that adopt inner panel 2 and outside plate 1 to constitute more, its structure is shown in accompanying drawing 4, accompanying drawing 5 and accompanying drawing 6, this inner and outer plates structure by punching press or riveting process be combined into, forms cavity to gain in strength by inner panel 2 and outside plate 1 between the inner panel of bending and the outside plate; The front cross rail of this structure has certain rigidity, can absorb effectively and transmission of power when head-on crash, has improved the safety performance of car load; But this double-layer steel plate structure, its total weight is bigger, has both increased the manufacturing materials cost, influences vehicle complete vehicle lightweight effect again; In addition, the double-ply plank frame also makes production process more, thereby has increased production process controlling unit and productive costs.
Summary of the invention
The utility model main purpose provides a kind of high strength front cross rail, and it adopts single plate structure, can alleviate the front cross rail overall weight effectively and realizes lightweight, and can simplify its production process and save manufacturing cost.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of high strength front cross rail, the front cross rail body that comprises arc, through one time punching molded unitary construction, its thickness is 2-3mm to described front cross rail body series by steel plate.For front cross rail, the collision performance in the central collision of automobile is its main performance index; Monomer front cross rail for this structure, through CAE sunykatuib analysis auto against effect the time, use the automobile of this structure front cross rail, in central collision, bigger raising has been arranged than the collision performance that adopts double-layer plate structure front cross rail, simultaneously its overall weight obtains by a relatively large margin reduction than the front cross rail of double-layer plate structure, thereby has improved the lightweight effect of vehicle complete vehicle.
For when guaranteeing car load central collision performance, improve car load lightweight effect as much as possible, as preferably, the steel plate thickness of punching press front cross rail body is 2.5mm.
The rigidity that improves front cross rail helps promoting the central collision performance, and as preferably, described front cross rail body middle part is at the groove that is respectively equipped with bar shaped on the bearing of trend of two ends; The bending of front cross rail body both side edges makes its cross-sectional plane stage casing be convex.
Therefore, the utility model is rational in infrastructure, has not only simplified manufacturing process, has been easy to production control, has also reduced the manufacturing materials cost, has especially improved the safety performance and the lightweight effect of car load.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of a kind of high strength front cross rail of the utility model; Accompanying drawing 2 is lateral plans of accompanying drawing 1; Accompanying drawing 3 is birds-eye vieies of accompanying drawing 1; Accompanying drawing 4 is the structural representations before improving; Accompanying drawing 5 is lateral plans of accompanying drawing 4; Accompanying drawing 6 is birds-eye vieies of accompanying drawing 4.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of high strength front cross rail of the utility model, shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, it comprises the front cross rail body 1 of arc; Front cross rail body 1 is to be the 2.5mm1500MPa high tensile steel plate through heating by thickness---PROCESS FOR TREATMENT such as punch forming---quenching---laser hole-cutting, side cut and the one-board integrative-structure of moulding.
Front cross rail body 1 middle part is at the groove 3 that is respectively equipped with bar shaped on the bearing of trend of two ends; The bending of front cross rail body 1 both side edges makes its cross-sectional plane stage casing be convex.
Evidence, front cross rail uses the molded this structure of 1500MPa high tensile steel plate direct heat of 2.5mm thickness of slab, replace the double-deck unitized construction that front cross rail inner panel that original B340/590DP two-phase high-strength steel stamping with the 1.8mm thickness of slab forms and front cross rail outside plate combine, the central collision effect of new front cross rail automobile through CAE sunykatuib analysis auto against effect the time has had bigger raising than original collision performance, and the more original front cross rail of weight has reduced more than 30% simultaneously.
