Description

Technical Field

[0001] The utility model relates to the technical field of profile processing, and more particularly to a roller mechanism of a profile rolling bending machine and the profile rolling bending machine. Background Art

[0002] Profile bending machine is a key equipment used for bending metal profiles (such as pipes, bars, special-shaped profiles, etc.). Its roller mechanism is the core component, mainly composed of roller shaft, roller and drive device. The roller is mounted on the roller shaft. Through the friction between the roller and the surface of the profile, the profile reaches the predetermined curvature under the action of progressive bending.

[0003] Traditional roller mechanisms typically use a fixed roller structure, meaning the rollers cannot be moved axially after installation. This makes it impossible to adjust the roller position according to the actual bending requirements of the profile, nor can it achieve spatial curve bending of the profile. Furthermore, to expand the scope of application, current profile bending machines use universal couplings connected to the drive motor, allowing the two rollers to adjust their spacing without adjusting the motor position. However, universal couplings require high maintenance and regular lubrication, resulting in high operating costs. Utility Model Content
