AI Technical Summary
The rack on the small rolling mill is prone to deflection during descent, causing misalignment between the rack and the support roller tooth ring, resulting in tooth collision. In severe cases, the rack may break.
At least three limiting components are provided on the hydraulic cylinder. Each limiting component includes a limiting cylinder and a slidingly connected limiting rod. The limiting rod is connected to the connecting seat. The friction is reduced by the limiting guide cylinder, sliding protrusion, and ball structure. A pressure sensor is also provided to monitor the offset status.
It enhances the structural stability and positional accuracy of the rack during movement, prevents deflection, ensures equipment safety and stable operation, and provides a basis for preventive maintenance.
