Its purpose is to ensure stable positioning and support of the rebar during the bending process, thereby ensuring bending accuracy and processing efficiency. This device typically features a precise positioning mechanism and a stable support structure, capable of handling the bending needs of rebar of varying diameters and lengths.

For this reason, we propose a steel bar bending positioning and supporting device. Utility Model Content

The outer walls of the multiple conveying rollers 22 are each provided with a plurality of limiting grooves 23. The steel bars are placed in the limiting grooves 23 between the two groups of conveying rollers 22. The two conveying rollers 22 are used to clamp the two ends of the steel bars to improve the stability of the steel bars during bending and prevent the steel bars from sliding along the outer walls of the conveying rollers 22 to cause safety accidents.

The steel bar can be limited by the plurality of grooves 19. When the steel bar slides, it will drive the plurality of guide rollers 25 to roll, and the friction between the steel bar and the protective plate 18 can be reduced by the guide rollers 25.

[0025] Working principle: The steel bar is placed in the limiting groove 23 between the two sets of conveying rollers 22.
