Working roller horizontally-moving device

Abstract

The invention is suitable for the technical field of metallurgical equipment, and provides a working roller horizontally-moving device. The working roller horizontally-moving device comprises a machine frame and wedge cylinder supports fixed to the machine frame, and further comprises wedge cylinders, wedges, bending roller blocks and fixing blocks. One side of each bending roller block is of a slope T-head structure. The wedges are of slope T-groove structures, slope T heads are located in slope T grooves, and meanwhile the slope T heads and the slope T grooves are coincident in slope gradient and are oppositely arranged. The bending roller blocks are located in the fixing blocks and can slide in a reciprocating mode under the guide effect of the fixing blocks, the fixed ends of the wedge cylinders are fixed to the wedge cylinder supports, and the movable ends of the wedge cylinders are connected with the wedges. By means of the working roller horizontally-moving device, auxiliary cylinders are removed, working roller horizontally-moving and replacing operation is simple and reliable, and the working roller horizontally-moving device can meet requirements of working roller bearing blocks in various modes and is wide in application range.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, in particular to a work roll horizontal moving device. Background technique [0002] In order to roll high-strength steel strips such as silicon steel, stainless steel and special steel, it is necessary to use a rolling mill with a smaller diameter of the work roll, and as the diameter of the work roll decreases, the horizontal deflection of the work roll increases significantly, and the horizontal stiffness decreases significantly. Shape control is very unfavorable. The horizontal deflection of the work roll can be reduced by using the work roll horizontal movement technology. In the prior art, the specific plan for the horizontal movement of the work rolls is as follows: setting wedges on the roll bending blocks on both sides to push the roll bending blocks, and then push the work roll chocks, so that the work rolls move along the rolling direction. Because the wedges on each ...
