[0002] Roll forming is a technique that obtains various open, closed, and wide deformation section metal profiles by continuously rolling and bending metal plates or strips. During the roll press process of steel pipes, the metal plates or strips are fed into a roll forming device, which is composed of a series of rollers. These rollers continuously roll and bend to apply pressure to the metal plates or strips, gradually deforming them into the desired shape of steel pipes.

The repeated disassembly and assembly of the rollers are time-consuming and labor-intensive, affecting production efficiency, increasing downtime, and increasing production costs. Moreover, repeated disassembly and assembly can lead to a decrease in connection precision, which may adversely affect the quality of finished steel pipes, causing defects such as cracks and folds in the cross section of the steel pipes. In the prior art, the roller fixing mechanism is removed as a whole by a driving device. The driving mechanism is placed horizontally, occupying a large space, and the driving mechanism components have large installation sizes, increasing the processing and manufacturing costs of the components.
