The rotating shaft 5 is rotatably connected to the penetration point of the processing table 1, and a forward and reverse motor 7 is fixedly installed on the lower surface of the processing table 1. A worm 8 is fixedly installed on the output end of the forward and reverse motor 7. The worm 8 is meshed with the worm wheel 6. The forward and reverse motor 7 is started to drive the worm 8 to rotate, and the rotation of the worm 8 and the worm wheel 6 meshed with it can drive the rotating shaft 5 to rotate. A positioning mechanism 9 for fixing the steel bars is provided on the processing table 1. By setting the positioning mechanism 9, the steel bars can be effectively prevented from popping out due to stress during the bending process.

[0024] The positioning mechanism 9 comprises a fixed block 91, a movable block 92, a threaded rod 93, a pressing plate 94, a bolt 95 and a handle 96; the fixed block 91 is fixedly mounted on the upper surface of the processing table 1, the inner wall of the fixed block 91 is slidably connected with the pressing plate 94, the inner wall of the fixed block 91 is threadedly connected with the bolt 95, and the bolt 95 penetrates the fixed block 91 and is rotatably connected to the upper surface of the pressing plate 94, the bolt 95 is rotated to drive the pressing plate 94 to move downward, so that the pressing plate 94 presses against the steel bar downward, and the upper and lower sides of the steel bar are pressed against by the pressing plate 94 in cooperation with the processing table 1, and the movable block 92 is slidably connected to the inner wall of the processing table 1, and the left and right sides of the steel bar are tightened by the fixed block 91 and the movable block 92. One end of the threaded rod 93 is rotatably connected to the inner wall of the processing table 1, and the other end of the threaded rod 93 passes through the processing table 1 and is fixedly installed with a handle 96. The threaded rod 93 is rotatably connected to the penetration point of the processing table 1, and the outer wall of the threaded rod 93 is threadedly connected to the inner wall of the movable block 92.

[0025] The above-mentioned pressure plate 94 is provided with a clamping mechanism 10 for improving the bending stability of the steel bar. By setting the clamping mechanism 10, the bending part of the steel bar can be clamped to prevent the steel bar from popping up during the bending process, thereby improving the bending quality of the steel bar. The clamping mechanism 10 includes a connecting rod 101 and a limiting plate 102. The connecting rod 101 is fixedly installed on the side wall of the pressure plate 94, and the limiting plate 102 is fixedly installed on the end of the connecting rod 101 away from the pressure plate 94. The pressure plate 94 squeezes the steel bar downward and cooperates with the connecting rod 101 to drive the limiting plate 102 to move downward synchronously. The limiting plate 102 is sleeved on the outer wall of the limiting rod 3, and the steel bar located at the limiting rod 3 is pressed downward by the limiting plate 102.

After the steel bar is fixed, the forward and reverse motor 7 is started to drive the worm 8 to rotate. The rotation of the worm 8 and the worm wheel 6 engaged with it can drive the rotating shaft 5 to rotate, and then the rotating shaft 5 can drive the turntable 2 to rotate. The rotation of the turntable 2 can drive the limit rod 3 and the bending rod 4 to rotate synchronously, and the bending rod 4 can rotate around the limit rod 3 with the rotating shaft 5 as the center. At this time, the bending rod 4 will squeeze the steel bar, causing the steel bar to bend on the outer wall of the limit rod 3, and the bending of the steel bar can be completed.

[0027] The pressure plate 94 squeezes the steel bars downward and cooperates with the connecting rod 101 to drive the limit plate 102 to move downward synchronously, and the limit plate 102 presses the steel bars located at the limit rod 3 downward. When the steel bars are bent at the outer wall of the limit rod 3, the limit plate 102 is limited to prevent the steel bars from popping up during the bending process, thereby improving the bending quality of the steel bars.
