[0025] Specifically, the heated steel bar is first passed through two rolling rollers 10, and then the output end of the motor 2 drives the toothed cam 1 3 to rotate, and the toothed cam 2 5 is further driven to rotate through the toothed belt 4. The rotation of the toothed cam 2 5 will drive the rotating shaft 7 to rotate, so that the gear 2 8 drives the rotating shafts 7 on both sides to rotate at the same time, and finally the rotating shaft 7 drives the two rolling rollers 10 to roll the steel bar and transport it forward at the same time. In this process, the fixed plate 2 11 plays a role in limiting the two rotating shafts 7 to prevent deviation, thereby ensuring the accuracy of the rolling process. Multiple groups of rolling rollers 10 are preset on the upper surface of the workbench 1 to achieve the purpose of gradual rolling and forming, which can greatly improve the production efficiency under the premise of ensuring the rolling quality.

[0027] Specifically, the cooling water in the cooling box 13 in the cooling assembly is used to cool the steel bars in the cooling bin 12 .

Since a plurality of rolling rollers 10 are preset on the upper surface of the workbench 1, rolling forming is performed step by step, thereby achieving a fast and stable rolling effect. The cooling water inside the cooling box 13 is then sent to the branch pipe 15, and at the same time, it is sprayed out through the nozzle 16 to quickly cool the rolled steel bars, thereby accelerating the rolling efficiency. At the same time, excess cooling water flows into the water pipe 18 through the inclined plate 17, and then is filtered through the filter box 19 and finally sent to the cooling box 13 for reuse, thereby achieving a resource-saving effect.
