Abstract
The utility model discloses the passive abnormity support D font pipe for commercial vehicle of a kind of clod wash on-line continuous explained hereafter and the single production of bending, solve existing plain edition equipment structure simple, cross sectional moment of inertia is little, cross section limited capacity, processing welding link is many, the low and problem of mounting process complexity of productivity.Comprise the steel plate that monoblock clod wash becomes D font, have solder joint (5) at the mating interface place of steel plate, section is D font.The utility model adopts clod wash welded pipe units continuous rolling roll forming, online weld shaping, online sawing production technology, and spiral-plate bending, weld shaping technique under bender line.
Description
Technical field
The utility model relates to a kind of shape steel rolled stock of alternative quarter bend, the passive profiled 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, the passive auxiliary auxiliary girder of existing commercial vehicle and auxiliary girder frame, individual layer C-type steel or multi-layer C shaped steel combination is adopted 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, mounting process is complicated, and many industry requirements improve cross sectional moment of inertia when profile is constant simultaneously, or carry out alleviating quality in existing space, 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 D font pipe, comprise the monoblock carbon steel board that clod wash becomes D font, steel plate sealing part is provided with welded seam (5), 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 and material, it is characterized in that: section of steel plate is D font, four angles of D font tube wall external frame are external arc (1), and the radius of external arc (1) is 2 ~ 4 times of steel plate wall thickness (3); Four angles of D font 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 (3); The scope of D font pipe square tube partial width (8) is 60mm ~ 420mm, and highly the scope of (7) is that 60mm ~ 500mm, D font pipe square tube part wide (8) high (7) is than being 1:0.5 ~ 1:3.5; The value of R shape part Inner arc (4) is 2 ~ 5 times of Inner arc (2), and the value of R shape part external arc (6) is that Inner arc (4) adds steel plate wall thickness (3), and wide (8) of D font pipe are 15:1 ~ 8:1 with steel plate wall thickness (3) ratio; Wall thickness (3) scope is 3mm ~ 16mm.
The material of D font pipe 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 the aspect such as extensive use commercial vehicle auxiliary girder, dumping car auxiliary girder, railway freight-car bottom girder, tower crane, technique steel structure, photovoltaic industry, adds the product variety of clod wash square tube, has widened the using scope of cold-bending square and rectangular pipe.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
