Abstract
The utility model discloses frame cold forming sectional steel for a vehicle carriage. The section shape of the cold forming sectional steel is an open shape defined by three sides, the side I and the lateral side II are connected to form a right angle, the side I and the lateral side III are connected to form an included angle alpha of 120-135 degrees, the length H of the side I is 150-300 mm, and the length B of the lateral side II is 50-120 mm. The frame cold forming sectional steel improves the mechanical performance, reduces steel use quantity for manufacturing the vehicle carriage and reduces self weight.
Description
Technical field
The utility model belongs to the Lightweight Steel Shape technical field, especially relates to a kind of vehicle car frame Lightweight Steel Shape.
Background technique
At present, the common vehicle section bar mostly is hot-rolled profile, and kind is single, and intensity is low.Along with development and national economy, the manufacturing of vehicle car is to development in pluralism, the purposes variation, and special mechanical equipment etc. have the occasion of specific (special) requirements to shaped steel, and existing Lightweight Steel Shape often can not meet the demands in kind and mechanical properties.
Summary of the invention
The purpose of this utility model is: a kind of mechanical property that improves compartment frame section bar is provided, alleviates the vehicle car frame Lightweight Steel Shape of deadweight.
The technical solution of the utility model is: the sectional shape of Lightweight Steel Shape is the uncovered type that three limits are formed, the limit I at right angles is connected with the side II, limit I and side III are angle α and are 120 ° ~ 135 ° and are connected that limit I length H is 150-300mm, and side II length B is 50-120mm.
The end of described side II and side III is identical with limit I perpendicular distance.
The wall thickness T of described limit I, side II, side III is 3-8mm,
The beneficial effects of the utility model are: the utility model has improved the mechanical property of compartment frame section bar greatly, has solved the problem that existing Lightweight Steel Shape kind and mechanical property can not be satisfied the demand, and reduces the steel using amount that vehicle car is made simultaneously greatly.The utility model can reduce the own wt of load-carrying vehicle greatly, simplifies the vehicle car linkage editor, enhances productivity.This compartment frame section bar is can continuous online clod wash rolling, and dimensional range is extensive, highly versatile, and the vehicle car of applicable all size mainly is applicable to the applications such as manufacturing of compartment frame, farm machinery and the engineering machinery of various load-carrying vehicles.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
From structural representation of the present utility model shown in Figure 1 as can be seen, the sectional shape of Lightweight Steel Shape is the uncovered type that three limits are formed, and on type steel production line, the three limit structures that limit I 1, side II 2, side III 3 are formed are that steel plate processes through clod wash.Limit I 1 at right angles is connected with side II 2, limit I 1 and side III 3 are angle α and are 120 ° ~ 135 ° and are connected, I 1 length H in limit is 150-300mm, side II 2 length B are 50-120mm, the wall thickness T of limit I 1, side II 2, side III 3 is 3-8mm, the end of side II 2 and side III 3 is identical with limit I 1 perpendicular distance, and just the end of side III 3 and limit I 1 perpendicular distance also are B, the yield strength 〉=235Mpa of Lightweight Steel Shape.As following example, limit I and side III are angle α and are 135 ° and are connected that limit I length H is 200mm, side II length B is 80mm, the end of side III 3 and limit I 1 perpendicular distance B are 80mm, and the wall thickness T of limit I, side II, side III is 5mm, and yield strength reaches 345Mpa.The utility model has improved the mechanical property of compartment frame section bar greatly, has reduced the steel using amount that vehicle car is made, and alleviates deadweight.
