Description

A H-shaped steel flange straightening machine

technical field

Background technique

H-shaped steel is widely used in large-scale buildings, water conservancy bridges, metallurgical industry and other industries. This kind of H-shaped steel is usually formed by welding. The plate is bent and deformed, so it needs a straightening machine to correct it. The current H-shaped steel flange plate straightening machine includes a driving roller and an upper pressure roller located above the driving roller and matched with the driving roller. The wheel reducer drives the transmission roller to rotate, relying on the weight of the H-shaped steel and the friction force between the outer roller surface of the upper pressing roller and the outer roller surface of the driving roller, so as to drive the H-shaped steel to move horizontally and linearly between the driving roller and the upper pressing roller. The roller and the driving roller correct the flange plate of the H-shaped steel. However, this correction method can only correct the flange plate on one side of the H-shaped steel, which causes asymmetry in the flange plates on the upper and lower sides of the corrected H-shaped steel, which affects the use.
