Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of angle steel cold addition, and in particular relates to a simple tooling for angle steel press bending forming. Background Art
[0002] The L-shaped angle steel section is a commonly used profile in steel structure buildings, and its processing technology is relatively mature. However, angle steel with a certain curvature is required on site for components such as steel structure maintenance ladders and guardrail handrails. At present, the method of bending and forming the angle steel with curvature on the maintenance site is to cut a slit at a certain distance on the back side of the angle steel limb to reduce the bending stiffness of the angle steel, and then use a bending mold to assist in manually bending it to a certain angle by folding instead of bending. After comparing it with the required angle, it is operated multiple times until it is bent into the required curvature. During the bending process of the angle steel, due to the high stiffness of the angle steel, the slit is time-consuming and labor-intensive. Manual bending assisted by a mold is difficult to bend and form in one go, and the accuracy of the bending curvature is limited. Multiple twisting and bending lead to a decrease in the bearing capacity of the angle steel, which also affects the appearance quality during use. Summary of the invention
[0003] The utility model aims to solve the deficiencies of the prior art and to provide a simple tool for angle steel bending and forming which has a simple structure and can quickly, accurately and non-destructively bend angle steel into a required curvature on site of steel structure maintenance ladders and guardrail handrails.

[0006] Furthermore, the simple tooling for angle steel press-bending and forming also includes a positioning bolt bracket and a clamping bolt bracket with bolt holes fixed on the operating panel, and the positioning bolts and the clamping bolts pass through the bolt holes to fix the angle steel.
