Abstract
The invention discloses a front bumper cross bar component of a truck and relates to the technical field of automobile manufacturing. The front bumper cross bar component comprises a cross bar and a supporting component arranged in the cross bar, the cross bar is of a shell formed by one-time rolling pulling with the upper portion shaped in rectangle and lower portion shaped in right trapezoid; the supporting component is provided with an oblique portion abutted against the oblique lumbar of the shell, two ends of the oblique portion are bent to form a connecting portion, and the connecting portion is fixedly connected with the straight lumbar opposite to the oblique lumbar of the shell. By the arrangement, problems that the front bumper cross bar component is high in manufacturing cost and unqualified production rate can be solved.
Description
Technical field
The present invention relates to field of automobile, especially a kind of cross bar assembly for front bumper for truck.
Background technology
Truck bumper absorbs to relax foreign impacts power, the safety device of protection vehicle body front and rear part, at present, car front/rear collision bumper is based on metallic material, be pressed into U-type groove steel with the steel plate stamping that thickness is more than 2 ~ 3 millimeters, surface treatment chromium plating, rivet or weld together with chassis side rail; There is a kind of front bumper for truck cross bar assembly as shown in Fig. 1 ~ Fig. 2, be made up of connecting panel 1 and cross bar 2, wherein connecting panel 1 is that bending part and cross bar 2 seam form front bumper, cross bar 2 is made up of bending plate 2-1, strut member 2-3 and shrouding 2-2, wherein bending plate 2-1 is the special-shaped bending part of open at one end, be welded on the small end of bending plate 2-1 after strut member 2-3 bending, shrouding 2-2 is the open end that channel is welded in bending plate 2-1, makes cross bar 2 form a closed hollow shell; The two ends of cross bar 2 need be pressed into arc by mould; The connecting panel 1 of this structure, the bending of cross bar 2 often need by large mold swaging, and manufacturing process often exists resilience, needs secondary reshaping, and cost of manufacture is large, and percent defective is higher.
Summary of the invention
The object of this invention is to provide a kind of front bumper for truck cross bar assembly, it can solve the problem that existing front bumper for truck cross bar establishment of component cost is large, percent defective is higher.
In order to solve the problem, the technical solution used in the present invention is:
This front bumper for truck cross bar assembly, comprises cross bar and is arranged at support component in described cross bar, and described cross bar is the shaping housing of rolling drawing, and described housing upper shape is oblong, and lower shape is right-angled trapezium; Described support component has the rake abutted against with the oblique waist of described housing, and form connecting portion after the two ends bending of described rake, the straight waist that described connecting portion is relative with the oblique waist of described housing is fixedly connected with.
In above technical scheme, further scheme is: in small end seam after described housing rolling drawing is shaping.
Further: the straight waist of described connecting portion and described housing is perpendicular, one end that two described connecting portions are connected with the straight waist of described housing has flanging towards the opposite.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention adopts rolling drawing forming process once to be pulled out by cross bar, saves rolled steel dosage and welding consumptive material, labour cost;
2, the present invention welds support component between the inclined-plane and relative straight flange of cross bar, guarantees that whole front bumper assembly is in subsequent forming process, and inclined-plane distortion greatly reduces, and percent defective reduces greatly.
Accompanying drawing explanation
Fig. 1 is prior art front bumper for truck front view.
Fig. 2 is the A-A line cutaway view of Fig. 1.
Fig. 3 is A-A line cutaway view of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
This front bumper for truck cross bar assembly, as shown in Figure 1, Figure 3, the support component comprising cross bar 2 and be arranged in cross bar 2, the cross-sectional upper part shape of cross bar 2 is oblong, and lower shape is right-angled trapezium, in small end seam after a rolling drawing is shaping; Support component has the rake 2-6 abutted against with the oblique waist 2-4 of cross bar 2, connecting portion 2-5 is formed after the two ends bending of rake 2-6, the straight waist that connecting portion 2-5 is relative with the oblique waist 2-4 of cross bar 2 is fixedly connected with, the straight waist of connecting portion 2-5 and cross bar 2 is perpendicular, one end that two connecting portion 2-5 are connected with the straight waist of cross bar 2 has flanging 2-7 towards the opposite, and flanging 2-7 is weldingly fixed on the straight waist of cross bar 2.
Claims (3)
