Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel processing technology, and in particular to an adjustable device for an H-beam straightening machine. Background Technology
[0002] The straightening machine is a specialized device for straightening welded H-beams. Its main drive rollers and upper pressure rollers are made of high-quality alloy steel and undergo heat treatment to ensure longevity. The machine is simple to operate and easy to learn. Rolled steel sheets often have some bends after exiting the rolling mill, and bending deformation and warping can occur during cooling and transportation. To obtain flatter steel plates, they need to be straightened by a straightening machine. When the steel plate enters the straightening machine, the unit force exerted by the upper and lower work rollers on the steel plate exceeds the yield stress of the steel plate in that state. This causes plastic and elastic deformation of the steel plate during the straightening process. Through repeated bending, the original unevenness of the steel plate is eliminated, resulting in a flatter steel plate.
[0003] Authorization announcement number CN218503035U discloses an H-beam flange straightening machine. This H-beam flange straightening machine includes a work frame, a positioning mechanism, a fixing mechanism, and a transmission mechanism. A motor is mounted on the work frame, and a rotating rod is installed inside the work frame. The output shaft of the motor is fixedly connected to the rotating rod via a coupling. This method can only adjust two rollers, and it cannot simultaneously straighten both sides of the H-beam. Furthermore, after straightening one side, a second straightening process is required, making the operation complex, time-consuming, and labor-intensive. Utility Model Content
