[0024] Working principle: first move the movable plate 141 according to the bending point of the steel bar in advance and use the stud 144 to lock it, adjust the distance between the baffle 142 and the top plate 11, and then connect the first electric push rod 12, the second electric push rod 13, the third electric push rod 15, the fourth electric push rod 24, and the motor 21 with the external control device and the power supply. At this time, operate the control switch of the motor 21, the motor 21 drives the driving wheel 211 to rotate, and the driving wheel 211 drives the rotating ring 23 to rotate. The rotating ring 23 rotates and the fourth electric push rod 24 is driven to rotate synchronously until the rotation is stopped after reaching the angle to be processed. The second electric push rod 13 pushes the clamping plate 131 to apply pressure to the rotating ring 23 to limit the rotation of the rotating ring 23, and then the steel bars to be bent (steel bars of a single model) are inserted into the mounting ring 22 and the limit seat 112 in turn, so that The end of the steel bar contacts with the baffle 142. At this time, the control switch of the third electric push rod 15 is operated. The third electric push rod 15 pushes the holder 151 to make it contact with the steel bar. At this time, the first electric push rod 12 and the fourth electric push rod 24 work synchronously. The first electric push rod 12 pushes the first push block 121, and the fourth electric push rod 24 pushes the second push block 241, so that the first push block 121 and the second push block 241 contact with the steel bar and apply thrust. One end of the steel bar is bent along the rotating sleeve 111, and the other end is bent along the arc-shaped through hole inside the mounting ring 22, thereby completing the special-shaped processing of the steel bar. After the bending is completed, the first push block 121, the second push block 241 and the holder 151 are separated from the steel bar and reset. At this time, lifting the left end of the steel bar can conveniently remove the steel bar from the top plate 11 and the mounting ring 22 to carry out the next steel bar bending processing.
