A driving roller shaft 14 is rotatably connected to the upper end of each support plate 13. A positioning mechanism is fixedly connected to the upper surface of the straightening platform 2. The positioning mechanism includes a servo motor 21, a first positioning block 22, a bidirectional screw 24, a slider 25, a second positioning block 26, a connecting plate 3, a clamping rod 32, and a clamping block 33. A gantry 4 is fixedly connected to the upper sides of the first positioning block 22 and the second positioning block 26. A hydraulic cylinder 41 is fixedly installed on the upper surface of the gantry 4. The telescopic rod in the hydraulic cylinder 41 is fixedly connected to a straightening block 42.

[0033] Among them, during the process of straightening the round steel bars, the round steel bars are conveyed to the lower side of the gantry 4 through the driving roller shaft 14, and the round steel bars are placed in the support groove 12 at the upper end of the support block 11. Then, the round steel bars are rotated to adjust the position to be straightened. Next, the round steel bars are positioned through the positioning mechanism. Then, the straightening block 42 is pushed downward by the hydraulic cylinder 41 to straighten the round steel bars.

[0034] Refer to Figures 3 to 5 , a positioning groove 23 is opened on the upper surface of the first positioning block 22. The front and rear ends of the bidirectional screw 24 are respectively rotatably connected to the front and rear ends of the positioning groove 23. The servo motor 21 is fixedly installed at the front end of the first positioning block 22. The output end of the servo motor 21 is fixedly connected to the front end of the bidirectional screw 24. Two groups of sliders 25 are slidably connected inside the positioning groove 23.
