AI Technical Summary

Technical Problem

The existing cold rolling line tension rolls have a separate structure between the roll shaft and the roll body, which allows oil and gas to enter the roll, affecting dynamic balance, causing vibration and tension fluctuations, increasing the risk of strip breakage during rolling, and making disassembly and assembly inconvenient and affecting maintenance efficiency.

Method used

The design employs a threaded connection of through rod, roller, positioning block and sleeve ring, combined with the rotation and engagement of ball bearings and rotating groove, to achieve quick assembly and disassembly. Automatic lubrication is achieved through the cooperation of sponge, spring, contact plate and limit block to ensure smooth roller rotation and lubrication effect.

Benefits of technology

It enables quick disassembly and automatic lubrication of the tension roller, improves maintenance efficiency, reduces workload, ensures the stability of roller rotation and lubrication effect, and avoids waste of lubricating oil.
