Problems solved by technology

[0002] At present, the reinforced frame of the side box supporting the existing commercial vehicles is designed and manufactured by square rectangular tube, C-shaped steel, sharp-angled tube or hot-rolled channel steel. There are many welding links, low yield and complex installation process. At the same time, many industries require to increase the moment of inertia of the section without changing the shape. Ordinary profiles cannot meet the development of existing fields. A profile with a wider range of adaptation is needed to replace it.

Embodiment Construction

[0009] The ON-shaped tube for special-shaped support includes a whole steel plate that is cold-bent into an ON shape, and a welding seam (12) is arranged at the seal of the steel plate. The welding forms include online high-frequency continuous welding, submerged arc continuous welding, laser continuous welding and Gas-shielded continuous welding, the welding form is selected according to the thickness of the steel plate (14) and the material. The radius of (1) is 2~4 times of the steel plate wall thickness (14); the four corners of the inner contour of the pipe wall are all inner arcs (13), and the radius of the inner arcs (13) is the steel plate wall thickness (14) 1~2.5 times; the width (10) of the ON-shaped tube ranges from 40mm to 150mm, the range of height (6) is 120mm~450mm, and the ratio of width (10) to height (6) is 1:3~1:5; ON The height of the short side (8) of the closed part of the shaped pipe is 20mm~200mm, and the closing angles are 90°, 90°, 135°, 135°, 90° re...

Abstract

The invention discloses an irregular rectangular pipe which is produced by using a cold-bending on-line continuous technique, is bent and singly produced and is used for supporting a commercial vehicle. The problems of the present common section bar of simple structure, small section inertia moment, limited section performance, many processing welding links, low yield and complex mounting technique are solved. The irregular rectangular pipe comprises an integrated cold-bent ON shaped steel plate, wherein a welding joint (12) is arranged at a butt-joint connector of the steel plate, and the cross section is of ON shape. According to the invention, a cold-bending welding pipe unit is used for continuously rolling, bending and forming. Online welding reshaping, online sawing production technique, single plate bending and offline welding reshaping technique of a bending machine are adopted.

Description

technical field [0001] The invention relates to a special-shaped steel that replaces a square-rectangular pipe, in particular to a special-shaped square-rectangular pipe for commercial vehicles that is produced by a cold-bending on-line continuous process and produced by bending a single piece. Background technique [0002] At present, the reinforced frame of the side box supporting the existing commercial vehicles is designed and manufactured by square rectangular tube, C-shaped steel, sharp-angled tube or hot-rolled channel steel. There are many welding links, low yield and complex installation process. At the same time, many industries require to increase the moment of inertia of the section without changing the shape. Ordinary profiles cannot meet the development of existing fields. A profile with a wider range of adaptation is needed to replace it. . Contents of the invention [0003] In order to make up for the functional deficiencies of ordinary profiles such as sm...
