Description

Technical Field

[0001] The utility model relates to the technical field of bending, and more specifically, to a roll bending machine. Background Art

[0002] In order to meet the profile bending process, some profile bending equipment with variable curvature has emerged on the market. Most of these profile bending equipment are based on the principle of three points forming a circle, and use the relative position change and rotational movement of the working rolls to cause continuous plastic deformation of the profile to obtain a profile workpiece with a predetermined shape.

[0003] However, the profile bending equipment on the market can only perform variable curvature bending of the profile in the same direction. If profile processing in both positive and negative directions is required, two feeding processes are still needed: first, press a positive arc on the profile workpiece, and then take out the profile workpiece and press a negative arc after changing the direction and position. This operation method requires repeated adjustment of the placement angle of the profile many times to make the bent profile meet the design requirements, and it is impossible to guarantee the accuracy of the transition position between the positive and negative arcs, thus affecting the processing quality and accuracy of the profile, and the operation is cumbersome, time-consuming and laborious.
