Abstract
The utility model discloses a longitudinal beam for a platform floor and relates to the technical field of automobile manufacturing. The cross section of bar-shaped steel is U-shaped; the U-shaped bar-shaped steel is formed by cold-rolling and then annealing the bar-shaped steel; the U-shaped opening of the bar-shaped steel is upward. Compared with the prior art, the longitudinal beam for the platform floor can solve the problems of high material cost and complex processing processes of the present longitudinal beam for the platform floor.
Description
Technical field
The utility model relates to field of automobile, the longeron on especially a kind of automobile compartment floor.
Background technology
The cabin floor longeron of the longeron of existing automobile compartment floor, especially heavy goods vehicles, because magnanimous size is larger, volume weight is larger, and difficulty of processing is larger.For increasing device resource not, avoid using large equipment, existing automobile bodies manufacturing enterprise is all generally the method processing that adopts steel plate bending welding.Because the steel plate tension degree of bending is poor, thus two block plates need to be bent into U-shaped after, mutually nested being welded, to strengthen longeron intensity, the longeron cross-sectional plane having welded as shown in Figure 1.So both caused the material cost of longeron higher, longeron weight is larger, has increased again manufacturing procedure, and nested welding difficulty is also larger, affects production efficiency.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of cabin floor longeron, high to solve existing cabin floor longeron material cost, the problem of manufacturing procedure complexity.
In order to address the above problem, the technical solution of the utility model is: this cabin floor longeron comprises the bar shaped steel that has groove, and the cross-sectional plane of described bar shaped steel is U-shaped; The cross-sectional plane of described bar shaped steel is U-shaped; Described bar shaped steel is the U-shaped bar shaped steel that cold rolling after annealing forms.
In technique scheme, more specifically technical scheme can also be: the U-shaped opening upwards of described bar shaped steel.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
This cabin floor longeron adopts rolling and forming of the cold rolling mode of U-shaped rolling equipment, bar shaped steel thickness after cold rolling is more accurate, and smooth surface, intensity are higher, it is better that the mechanical characteristicss such as annealed rear tensile strength obtain more than the bending of prior art, both reduced operation, reduce the defect causing due to welding, improve welding efficiency, simultaneously on the basis that reaches mechanical characteristics, only need to use a steel bar to manufacture longeron, saved approximately 40% feed stock cost, the weight of whole longeron also alleviates greatly.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of prior art;
Fig. 2 is the front view of the utility model embodiment;
Fig. 3 is the cross-sectional view of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail:
This cabin floor longeron as shown in Figure 2 to Figure 3, it comprises the bar shaped steel 1 that has groove, the cross-sectional plane of bar shaped steel 1 is U-shaped; The U-shaped opening upwards of bar shaped steel 1.The U-shaped bar shaped steel that bar shaped steel 1 forms for cold rolling after annealing.Adopt rolling and forming of the cold rolling mode of U-shaped rolling equipment, bar shaped steel thickness after cold rolling is more accurate, and smooth surface, intensity are higher, it is better that the mechanical characteristicss such as annealed rear tensile strength obtain more than the bending of prior art, both reduced operation, only need to use a steel bar to manufacture longeron, saved approximately 40% feed stock cost.
Claims (2)
1. a cabin floor longeron, comprises the bar shaped steel that has groove, it is characterized in that: the cross-sectional plane of described bar shaped steel is U-shaped; Described bar shaped steel is the U-shaped bar shaped steel that cold rolling after annealing forms.
2. cabin floor longeron according to claim 1, is characterized in that: the U-shaped opening upwards of described bar shaped steel.
