A corrugated roll for lamination rolling with stacked sheet structure

Abstract

The invention relates to the technical field of rolls, in particular to a corrugated roll with laminated structure for rolling laminated plates. It includes the roll mandrel, laminations, support rings and lock nuts. Its structure is that a number of laminations are set side by side on the roll mandrel, and the adjacent laminations are close to each other. The retaining ring is positioned and supported, and the outer end surface of the supporting retaining ring is fastened by a lock nut; the circumferential corrugation of the lamination itself and the phase difference between the laminations relative to the roll mandrel constitute the corrugated surface of the roll. When the metal laminate is rolled by such a roll, the bonding strength at the interface of the two metals can be improved, coordinated deformation can be promoted, and warping can be suppressed.

Description

technical field [0001] The invention relates to the technical field of rolling rolls, in particular to a corrugated roll for rolling a laminated plate with a laminated structure. Background technique [0002] As high-end industries such as aerospace, marine, nuclear power, shipbuilding, and electronics put forward higher and stricter requirements for material performance, traditional single materials are far from meeting product needs, so two or more metal materials are used. The respective performance advantages rolled into laminates have become the solution that has attracted much attention. However, due to the large performance differences between different metal materials, the application of traditional rolling methods is prone to problems such as large residual stress, low bonding strength, and serious warpage. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned defects, the purpose of the present invention is to provide a corrugated roll for lami...
