Description
Technical field
The utility model relates to a kind of shape steel rolled stock of alternative quarter bend, the passive special-shaped square quarter bend for commercial vehicle of particularly a kind of clod wash on-line continuous explained hereafter and the single production of bending.
Background technique
At present, known existing commercial vehicle plays a supportive role side chest frame, adopt square tube, C-type steel, wedge angle pipe or hot-rolled steel channel to manufacture and design, its structure is simple, cross sectional moment of inertia is little, cross section limited capacity, processing welding link is many, productivity is low, and mounting process is complicated, and many industry requirements improve cross sectional moment of inertia when profile is constant simultaneously, common section bar cannot meet the development in existing field, needs the wider section bar of a kind of accommodation to substitute.
Summary of the invention
For make up common section bar functionally as cross sectional moment of inertia is little, the deficiencies such as cross section limited capacity, the mechanical property of the existing square tube of the utility model, there is again the structural feature of angle steel, C-type steel, adopt shaping continuous Type of Welding simultaneously, decrease the extensive work of line aft-loaded airfoil welding, its mechanical property is better than the mechanical property of square tube.
The utility model is solved the problem by following scheme:
Special-shaped support is managed with OM shape, comprise the monoblock steel plate that clod wash becomes OM shape, steel plate sealing part is provided with solder joint (10), its Type of Welding has online high frequency continuous welding, submerged arc continuous welding, laser continuous welding and air protection continuous welding, Type of Welding is selected according to the difference of steel plate wall thickness (12) and material, its section is OM shape, and four angles of tube wall external frame are external arc (1), and the radius of external arc (1) is 2 ~ 4 times of steel plate wall thickness (12); Four angles of tube wall Internal periphery are Inner arc (2), and the radius of Inner arc (2) is 1 ~ 2.5 times of steel plate wall thickness (12); The scope of OM shape pipe width (11) is 40mm ~ 150mm, and highly the scope of (8) is 140mm ~ 550mm, and wide (11) high (8) are than being 1:3.5 ~ 1:5; Part of remaining silent minor face (3) height value is 20mm ~ 200mm, and angle of remaining silent is respectively 90 °, 90 °, 135 °, 45 °; The length of opening minor face (7) is 25mm ~ 60mm; The length of opening edge (6)
; Steel pipe is remained silent the length of edge sealing (9)
; Location, turning (4)
, wherein, B1 is steel pipe opening edge length, and B is steel pipe overall width, and t is thickness of steel pipe, and L is that steel pipe is remained silent edge sealing length, and K is that steel pipe is remained silent bond length, and H1 is location, turning, and H is steel pipe total height, and E is steel pipe opening bond length; Wall thickness (12) scope is 3mm ~ 16mm.
Special-shaped support OM shape tubing matter is carbon steel, high-strength automobile steel and stainless steel, and its yield limit and tensile strength Applicable scope are respectively 195MPa ~ 960MPa, 350MPa ~ 1260MPa.
The utility model can be widely used in the aspects such as commercial vehicle side chest frame, dumping car, railway freight-car side bar, tower crane, technique steel structure, photovoltaic industry, adds the product variety of clod wash square tube, has widened the using scope of clod wash square tube.
