[0002] During the processing of special-shaped plates, they usually need to be bent to facilitate the processing and forming of the special-shaped plates.

[0003] A Chinese patent with application publication number CN217451628U discloses a three-dimensional bending device for a bending machine for special-shaped cover plates. In this patent, when a steel column needs to be bent, the bending handle can be rotated to drive the bending rod to rotate, so that the steel column is bent by the force of the bending rod, and the bending angle of the steel column diameter can be directly observed through the bending angle scale. The use effect is better, and the automatic rotation and turning can be performed through the rotating component, which is more labor-saving and has a high degree of automation.

[0004] When using the above patent, we found that the device is not convenient for adjusting the bending position of the plate. When the bending position is inaccurate, the plate position needs to be manually readjusted, which affects the efficiency of bending the plate. Therefore, we proposed a bending device for special-shaped plates. Utility Model Content
