Abstract
The utility model discloses a kind of special-shaped support 9 font pipes, solve existing plain edition equipment structure simple, cross sectional moment of inertia is little, cross section limited capacity, and processing welding link is many, the low and problem of mounting process complexity of productivity.Comprise the steel plate that monoblock clod wash becomes 9 fonts, have solder joint (6) at the mating interface place of steel plate, section is 9 fonts.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, is specially the passive profiled square quarter bend for commercial vehicle of a kind of clod wash on-line continuous explained hereafter and the single production of bending.
Background technique
At present, the passive auxiliary girder of existing commercial vehicle, 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 the deficiency being solved its common section bar by following scheme:
Special-shaped support 9 font pipes, comprise the steel plate of monoblock cold roll forming 9 font, solder joint (6) is had at the mating interface place of steel plate, Type of Welding can select high frequency continuous welding, submerged arc continuous welding, laser continuous welding or air protection continuous welding according to steel plate wall thickness (7) and material, it is characterized in that: section is 9 fonts, four angles of tube wall external frame are external arc (1), and outer arc radius is 2 ~ 4 times of steel plate wall thickness (7); Four angles of Internal periphery are Inner arc (2), and inner arc radius is 1 ~ 2.5 times of steel plate wall thickness (7); The scope of the width (9) of the steel plate of 9 fonts is 40mm ~ 200mm, and highly the scope of (4) is 80mm ~ 400mm, and wide (9) high (4) are than being 1:2 ~ 1:3.5; Part of remaining silent minor face (3) height value is 20mm ~ 200mm; Steel pipe is remained silent edge sealing (8) length
, opening edge (5) length
, angle of remaining silent is respectively 90 °, 90 °, 135 °, 45 °, and wherein L is that steel pipe is remained silent the length of edge sealing (8), and B is steel pipe overall width, and t is steel plate wall thickness, and K is that steel pipe is remained silent the length of minor face (3), and B1 is the length of steel pipe opening edge (5); Wall thickness (7) scope is 3mm ~ 16mm.
The material of 9 font pipes is carbon steel, high-strength automobile steel and stainless steel, and its surrender authority and tensile strength Applicable scope are respectively 195MPa ~ 960MPa, 350MPa ~ 1260MPa.
The utility model can extensive use commercial vehicle strengthens longeron, the aspects such as longeron, railway freight-car central sill, tower crane, technique steel structure, photovoltaic industry strengthened by dumping car, add the product variety of clod wash square tube, widen the using scope of cold-bending square and rectangular pipe.
