Abstract

The utility model discloses a kind of special-shaped support figure-six pipe, 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 figure-six, have solder joint (7) at the mating interface place of steel plate, section is figure-six.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

Special-shaped support figure-six pipe

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 side plate head of a secret society frame that plays a supportive role of known existing commercial vehicle, square tube, C-type steel, wedge angle pipe or hot-rolled steel channel single section bar is adopted to manufacture and design, also can manufacture with multiple section bar organization 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 existing 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 6 font pipes, comprise the steel plate of monoblock cold roll forming figure-six, solder joint (7) 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 (3) and material, it is characterized in that: section is figure-six, four angles of tube wall external frame are external arc (1), and radius is 2 ~ 4 times of steel plate wall thickness (3); Four angles of Internal periphery are Inner arc (2), and radius is 1 ~ 2.5 times of steel plate wall thickness (3); The scope of the width (10) of figure-six steel plate is 40mm ~ 200mm, and highly the scope of (4) is 80mm ~ 400mm, and wide (10) high (4) are than being 1:2 ~ 1:3.5; Part of remaining silent minor face (9) height value is 20mm ~ 200mm; Steel pipe is remained silent edge sealing (8) length , the long limit of opening (5) length , opening minor face (6) length range is 25mm ~ 60mm, and angle of remaining silent is respectively 90 °, 90 °, 110 °, 70 °, 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 N is the length on the long limit of steel pipe opening (5); Wall thickness (3) scope is 3mm ~ 16mm.

The material of figure-six pipe 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 increase the cross sectional moment of inertia of steel pipe, reduce welding link, and technique is simple, can the aspect such as extensive use commercial vehicle side plate head of a secret society frame, self-discharging vehicle sideboard head of a secret society frame, railway freight-car side bar, tower crane, technique steel structure, photovoltaic industry, add the product variety of clod wash square tube, widen the using scope of cold-bending square and rectangular pipe.

Accompanying drawing explanation

Accompanying drawing is structural representation of the present utility model.
