Abstract

The invention discloses a special-shaped rectangular pipe. The pipe with a function of supporting is applied to commercial vehicles and produced by means of online continuous cold-bending process and single-pipe bending process. The problems of simple structure, small second moment of area, limited section performance, excessive machining and welding procedures, low yield and complexity in installation process of existing normal sections are solved. The pipe comprises a steel plate integrally forming an OM shape by cold bending, a weld seam (10) is reserved at the butt joint of the steel plate, and the cross section of the steel plate is in the OM shape. A cold-bending pipe welding set is adopted for continuous roll bending, online welding shaping, online saw cutting, single-plate bending and offline welding shaping of a bending machine.

Description

OM shape pipe for special-shaped support

Technical field

The present invention relates to a kind of shape steel rolled stock of alternative quarter bend, particularly a kind of passive special-shaped square quarter bend for commercial vehicle with clod wash on-line continuous explained hereafter and the single production of bending.

Background technique

At present, the known existing commercial vehicle side chest frame that plays a supportive role, adopt square tube, C shaped steel, wedge angle pipe or hot-rolled steel channel to manufacture and design, it is simple in structure, cross sectional moment of inertia is little, and cross section performance is limited, processing welding link is many, productivity is low, mounting process complexity, and many industry requirements improve cross sectional moment of inertia in the situation that 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

As little in cross sectional moment of inertia for making up in the function of common section bar, the limited deficiency that waits of cross section performance, the mechanical property of the existing square tube of the present invention, there is again the structural feature of angle steel, C shaped steel, adopt the continuous Type of Welding of moulding simultaneously, the extensive work that has reduced processing welding after line, its mechanical property is better than the mechanical property of square tube.

The present invention addresses the above problem by following scheme:

OM shape pipe for special-shaped support, comprise that clod wash becomes the monoblock steel plate of OM shape, be provided with solder joint (10) at steel plate sealing part, 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 (10) 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 (10); In tube wall, four angles of profile are interior circular arc (2), and the radius of interior circular arc (2) is 1 ~ 2.5 times of steel plate wall thickness (10); 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; The part of remaining silent minor face (3) height value is 20mm ~ 200mm, and the angle of remaining silent is respectively 90 °, 90 °, and 135 °, 45 °; The length of opening minor face (7) is 25mm ~ 60mm; The length of opening edge (6) ; The remain silent length of edge sealing (9) of steel pipe ; 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 the steel pipe edge sealing length of remaining silent, and K is the steel pipe bond length of remaining silent, and H1 is location, turning, and H is steel pipe total height, E is steel pipe opening bond length; Wall thickness (12) scope is 3mm ~ 16mm.

Special-shaped support is carbon steel, high-strength automobile steel and stainless steel by OM shape tubing matter, and its yield limit and tensile strength Applicable scope are respectively 195MPa ~ 960MPa, 350MPa ~ 1260MPa.

The present invention 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, has increased the product variety of clod wash square tube, has widened the using scope of clod wash square tube.
