[0001] The utility model belongs to the field of processing equipment for escalator components, and particularly relates to a roll bending equipment. Background Art

[0002] At present, the processing method for L-shaped angle steel bends in the entire escalator component industry is draw bending, and the draw bending process has the following deficiencies:

[0003] 1. The operation of a draw bending machine generally requires 2-3 people to operate, which causes a large waste of human resources.

[0004] 2. Draw bending requires adding a certain operation allowance on the basis of the net size.

[0005] 3. Since fixtures are needed to fix both ends of the pressing rail for stretching and shaping during the draw bending process, the cross-sectional profile of the L-shaped angle steel is prone to distortion and deformation after processing, thus affecting its usability.

[0006] 4. Due to the singularity of the draw bending die, a draw bending die needs to be opened for each processing radius, which not only causes waste of resources but also occupies space for storage.

[0007] Therefore, in view of the deficiencies of the above solutions in actual production and implementation, a roll bending equipment is provided to solve the above technical problems. Summary of the Utility Model
