Detachable roller special for composite plate rolling

Abstract

The invention relates to the technical field of composite plate rolling, in particular to a detachable roller special for composite plate rolling. The detachable roller comprises a core shaft, rollersleeve pieces, fastening screws, nuts and the like. The three or more completely-identical roller sleeve pieces are mounted outside the core shaft, and the roller sleeve pieces can be independently demounted. The roller sleeve pieces are divided into flat roller sleeve pieces and corrugated roller sleeve pieces, and the corrugated cross section on each corrugated roller sleeve piece is designed into a sine function curve or other function curves. The positions of the roller sleeve pieces can be aligned in the axial direction of the roller so as to meet mounting of the roller sleeve pieces of different widths. The connected parts of the corrugated roller sleeve pieces are trough positions, and the influence of the connecting parts on the rolling surface of a composite plate is reduced. Thedetachable roller is simple in mounting during use, the roller replacement time is saved, the rolling pass is reduced, and the production efficiency of composite plate rolling is improved.

Description

technical field [0001] The invention relates to the technical field of composite plate rolling, in particular to a detachable special roll for composite plate rolling. Background technique [0002] The roll is a tool for plastically deforming the rolled piece on the rolling mill, and is an important consumable part that determines the efficiency of the rolling mill and the quality of the plate. In the existing rolling production of clad plates, the rolls used are all flat rolls and are of integral structure, requiring multi-pass rolling. The roll surface of the integral structure is severely worn during the rolling process. Once the wear limit is reached, the entire roll will be scrapped, resulting in waste of resources, increasing production costs, and changing rolls is time-consuming and laborious, affecting production efficiency. Contents of the invention [0003] In order to solve many problems existing in the integral structure of the roll, the present invention prov...
