Then the platform lifting cylinder ascends and rotates along the rotation axis at the same time, the steel bar 23 to be bent is bent by taking the auxiliary fixing rod 18 as an axis, and finally the steel bar is reset. The whole process realizes full-automatic control through a PLC control system. The on-line bending automation of the stirrups is realized, the limitation of the traditional steel bar bending process is broken through, and unmanned and less unmanned steel bar processing can be realized; automatic continuous operation can be realized, and the processing efficiency of the steel bars is greatly improved; flexible and changeable, and the maximum bending capability can be realized by adjusting the configuration parameters of the cylinder.
