[0002] The bar mill is a kind of equipment for processing metal materials, which can change the metal bar into different shapes and sizes, and it occupies an important position in the metal processing industry. The guide is a structure installed on the bar mill to help the rolled piece accurately and stably enter and exit the bar mill roll pass according to the predetermined direction and state. With the continuous development of continuous casting technology, the size of continuous casting billet is various, which requires the size of the guide of the rough rolling of the steel production line to be changed accordingly, especially the rolling entry guide of the high-strength rough rolling mill. It not only requires high strength, but also requires the two guide wheels on the guide to accurately clamp the red steel, so that the red steel can enter the rolling mill for rolling in an accurate state. In order to make the two guide wheels accurately clamp the red steel, the distance between the two guide wheels needs to be adjusted. In the existing rolling entry guide, the two guide wheels used to guide the movement of the red steel are difficult to move after installation. To adjust the distance between the two guide wheels, the original guide wheel needs to be disassembled, and then the position of the two guide wheels is reset based on actual needs, and then the guide wheel is reinstalled. This adjustment method is relatively cumbersome and time-consuming.
