Description

Technical Field

[0001] The utility model relates to the technical field of straightening machines, in particular to an H-shaped steel flange straightening machine with a function of preventing workpiece displacement. Background Art

[0002] The straightening machine is a special equipment for straightening welded H-beams. The main drive roller and the upper pressure wheel are made of high-quality alloy steel and heat-treated to ensure the service life. The machine is simple to operate and easy to learn. After the rolled piece comes out of the roller room, it is often slightly bent. During the cooling and transportation process, it will also produce bending deformation and warping. In order to obtain a flatter steel plate, it needs to be straightened by the straightening machine. The straightening machines are arranged behind the main rolling mill and the normalizing furnace respectively. The steel plate after rolling and heat treatment is transported to the straightening machine by the roller table for straightening. The straightening working roll of the straightening machine applies a straightening force to the flange of the H-beam to straighten it.

[0003] In actual use, some straightening machines currently have H-shaped steel plates that are usually long. As the straightening work proceeds, they are prone to offset if not positioned during movement. If the correction angle is offset, correction deformation is likely to occur. For this reason, we propose an H-shaped steel flange straightening machine with anti-workpiece displacement function to solve the above problem. Utility Model Content
