Abstract
The utility model discloses a crossbeam of a heavy truck. The utility model adopts the technical scheme that the crossbeam of the heavy truck comprises a body with an arch top, wherein vent holes are formed on the arch top. The crossbeam of the heavy truck has the advantages of simple structure and reasonable design, an internal surface of the arch top of the crossbeam can be uniformly painted during electrophoresis of a frame, painting time is shortened, and painting quality is improved. When the crossbeam with the structure is produced, adding of a process is not required, four vent holes are required to be formed in a punching or blanking process, production beat time is shortened, production cost is reduced, and the painting quality of the frame is improved.
Description
Technical field
The utility model relates to and is a kind of heavy card crossbeam.
Background technology
The crossbeam of heavy duty truck is connected with the left and right longeron of vehicle frame through left and right bearing, is a vitals of frame assembly.During the frame assembly electro painting, crossbeam arch top is an enclosure space, and air can't be discharged, and bottom surface, crossbeam arch top can't electro painting.Must carry out touch-up paint, but the touch-up paint effect is undesirable, influences the coating quality of frame assembly.
Summary of the invention
The utility model is to the deficiency of prior art, and the technical scheme of heavily blocking crossbeam that also can evenly paint when a kind of inside face at crossbeam arch top is provided at the vehicle frame electrophoresis.
The utility model is realized through following technical measures: a kind of heavy card crossbeam, comprise the body that has the arch top, and said arch top is provided with deflation hole.
The concrete characteristics of the utility model also have, and above-mentioned deflation hole has four.
The diameter of above-mentioned deflation hole is 6-12mm.
The beneficial effect of the utility model is: it is simple in structure, and is reasonable in design, and crossbeam arch top inner surface also can evenly be painted when the vehicle frame electrophoresis, has reduced the time of japanning, and has improved the quality of japanning.When producing this structure crossbeam, need not to increase operation, go out four deflation holes towards operation and get final product fall dashing or cut out, both shortened productive temp, the minimizing productive costs has also improved the japanning quality of vehicle frame.
Description of drawings
Fig. 1 is the front view of the utility model specific embodiment.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Among the figure, 1, the arch top, 2, deflation hole, 3, the inside face at arch top.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, through a specific embodiment, this programme is set forth below.
Shown in accompanying drawing, a kind of heavy card crossbeam comprises the body that has arch top 1, and said arch top 1 is provided with four deflation holes 2, and the diameter of deflation hole 2 is 6-12mm.When producing the utility model, need not to increase original operation,, increase protruding, the die of four deflation holes 2, during production, go out four deflation holes 2 at blank operation and get final product only in the relevant position of cutting die.
Can know that through above-mentioned description the utility model is simple in structure, reasonable in design, crossbeam arch top inner surface 3 also can evenly be painted when the vehicle frame electrophoresis, reduce the time of japanning, and improved the quality of japanning.When producing this structure crossbeam, need not to increase operation, both shortened productive temp, reduce productive costs, also improved the japanning quality of vehicle frame.
The utility model can pass through or adopt existing techniques in realizing without the technical characterictic of describing; Repeat no more at this; Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited in above-mentioned giving an example; Variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of the utility model also should belong to the protection domain of the utility model.
