[0002] Concrete poles are commonly used infrastructure in fields such as electricity and communications. Their quality and performance are directly related to the safe and stable operation of the power grid. Concrete poles are composed of steel bars and concrete. During the concrete pole production process, the steel bars are first cut and bent to form the required ring structure. The bent bars are then placed in a mold at a specific spacing and position and secured together with steel wire to form a steel cage.

[0003] The traditional method of forming steel bar rings mainly relies on manual operation. Usually, the steel bar is placed on a workbench, one end of which passes between the positioning stop rod and the positioning plate, and then the end of the steel bar is manually moved so that the steel bar is bent into a ring structure along its circumferential direction under the restriction of the positioning plate, and then cut off using a cutting device. This forming method is not only labor-intensive and inefficient, but also easy to scratch the hands during the bending process of the steel bar, posing certain safety hazards. Some existing steel bar forming devices can only process steel bar rings of fixed diameter, which is difficult to meet the processing needs of concrete poles with different diameters.
