[0019] This utility model provides an H-beam straightening machine, which has the following beneficial effects:

[0020] In this invention, by cranking the first handwheel, the first adjusting screw rotates, causing the first lifting seat to move up and down, thus pressing down the top roller and providing initial correction force for the H-beam. Turning the control lever applies pressure to the hinge plate, ensuring close contact between the correction roller and the H-beam for precise correction. By cranking the second handwheel, the second adjusting screw rotates, causing the second lifting seat to move up and down, adjusting the height of the drive roller. After the drive roller contacts the bottom surface of the H-beam, the first motor is started, driving the roller to rotate and conveying the H-beam for continuous correction. Throughout the correction process, the operator only needs to operate the handwheel and control lever to achieve precise correction of the H-beam. This invention has advantages such as simple operation, adjustable correction accuracy, and good adaptability, meeting the correction needs of H-beams of different specifications and improving production efficiency and product quality.

[0021] Furthermore, in this invention, the height of the partition is adjusted by running two sets of No. 2 motors, and the position of the two sets of positioning rollers can be adjusted by telescopic hydraulic rods. The setting of the two sets of positioning rollers ensures the straightness and angular accuracy of the H-beam during the correction and conveying process, thereby improving the correction quality and ensuring the consistency and reliability of the product.
