[0002] A tension straightening roller is a common metal processing equipment that can stretch and straighten metal sheets during the processing of metal sheets. During the straightening process, the tension straightening roller is in continuous contact with the high-temperature metal sheet and is subjected to friction, load and temperature changes over a long period of time, which causes various damages to its surface and interior. When the damage accumulates to a certain extent, it must be replaced to maintain production safety and quality.

[0003] However, the existing tension leveling rollers are of an integral structure, which requires replacement of the whole unit when worn, increasing the operating costs for enterprises. In addition, the tension leveling rollers are mounted on bearing seats by rotating roller shafts at both ends. When replacing tension leveling rollers, the roller shafts need to be removed from the bearing seats and then new roller shafts need to be installed on the bearing seats, which is time-consuming and labor-intensive and not conducive to the promotion and use of the equipment.

[0004] Therefore, in order to solve the above problems, an assembled tension straightening roller is proposed. Utility Model Content
