A rolling mill with a work roll changing mechanism

Abstract

The invention discloses a rolling mill with a work roll replacing mechanism, and belongs to the field of rolling mill equipment. The rolling mill comprises a rolling mill housing, a work roll system, a supporting roll system and the roll replacing mechanism. The work roll system comprises an upper work roll and a lower work roll. The two ends of the upper work roll are fixed to an upper roll seat, the two ends of the lower work roll are fixed to a lower roll seat, and roll bottom wheels are arranged at the bottom of the lower roll seat. The supporting roll system comprises an upper supporting roll and a lower supporting roll. The roll replacing mechanism comprises transverse hydraulic cylinders, sliding blocks, rail plates, longitudinal hydraulic cylinders and a push hydraulic cylinder. The transverse hydraulic cylinders are arranged at the positions, on the two sides of the lower roll seat, of the rolling mill housing, and piston rods of the transverse hydraulic cylinders are fixedly connected with one sides of the sliding blocks. The rail plates are arranged on the two sides below the lower work roll, and the two ends of the rail plates are fixedly connected with the other sides of the sliding blocks respectively. The longitudinal hydraulic cylinders are arranged below the transverse hydraulic cylinders. The push hydraulic cylinder is arranged at one end of the lower roll seat. According to the technical scheme, the work rolls can be replaced rapidly, the roll replacing efficiency is high, and no equipment space is occupied.

Description

technical field [0001] The invention relates to the technical field of rolling mill equipment, and more specifically, relates to a rolling mill with a work roll changing mechanism. Background technique [0002] The rolling mill is a commonly used mechanical equipment in the metallurgical industry. When the rolling mill equipment is working, the roll system is generally composed of backup rolls, work rolls, etc. The rolls in the roll system are always subjected to rolling forces that change in direction and size; Long-term use of the rolls will cause fatigue wear or damage, and the rolls need to be maintained or replaced; in the prior art, the replacement of the rolls is usually achieved by pushing and pulling the traditional manual and overhead cranes, but because the rolls are made of iron and heavy, artificial The method not only wastes time, but also easily causes danger, especially in the high-span and platform of the workshop. During the production roll change process, ...
