Abstract

The invention discloses a metal composite plate rolling technique based on corrugated surface combining type blank forming and belongs to the technical field of machining of materials of metal composite plate strips. The metal composite plate rolling technique comprises the following steps that a metal base plate and a doubling plate are selected, arc-shaped base plate ripples and arc-shaped doubling plate ripples matched with the arc-shaped base plate ripples are rolled on the combined surfaces of the base plate and the doubling plate respectively, the section of each arc-shaped toothed ripple is in the shape of an arc or an elliptic arc or a sine wave, the height of each arc-shaped ripple is s, the width of each arc-shaped ripple is t, the thickness of the doubling plate is h, s / h=0.01-0.9, and t=(10-20)s; the base plate and the doubling plate are cleaned and stacked together, the base plate ripples and the doubling plate ripples are engaged, blank forming is conducted, and a composite plate blank comprises a double-layer metal composite plate blank or a three-layer metal composite plate blank or a four-layer metal composite plate blank; and a composite plate strip is obtained through rolling. By the adoption of the metal composite plate rolling technique, the technical problems that when a dissimilar metal composite plate is produced, the binding performance of a combined interface is poor, and bending, cracks and large residual stress occur are solved, the combining efficiency is high, and the binding strength is improved essentially.

Description

technical field [0001] The invention belongs to the technical field of material processing of metal composite plates and strips, and in particular relates to a process for making billets and rolling metal composite plates with corrugated joint surfaces.
