Rolling mill auxiliary jig

Abstract

The invention provides a rolling mill auxiliary jig, and belongs to the field of rolling mill roller assembling and disassembling devices. The rolling mill auxiliary jig comprises an assembling and disassembling head which can do up-down vertical movement and front-back horizontal movement. The assembling and disassembling head comprises an upward and backward bend at the front end and a plane structure. The bend is matched with a to-be-assembled/disassembled rolling mill roller. The plane structure is located below the bend, and the rolling mill roller can be conveniently ejected when assembled. The rolling mill roller can be mechanically assembled and disassembled, labor intensity is reduced, and safety and work efficiency are improved.

Description

technical field [0001] The invention belongs to the field of rolling mill equipment, in particular to an auxiliary jig for rolling mills. Background technique [0002] The rolling mill needs regular maintenance. Due to the lack of suitable disassembly and replacement facilities during the maintenance process, the original hoisting equipment is mostly used. However, the rolls of the rolling mill are large in size and heavy in weight. During the maintenance process, a hoisting mechanism needs to be added, and there are many disassembly steps. The process is long, labor-intensive, and safety factor is low; in addition, during the hoisting process, the lifting and lowering of the crane is unstable, and the assembly precision between the roller and the bearing in the archway is very high, so no matter how slow and careful, it often occurs Bearings are damaged by impact, and in severe cases, there will be a dilemma that they cannot be installed or removed, which often delays the t...
