Abstract

The invention discloses a preparation method of a crossed corrugated interface metal composite plate, and relates to the technical field of metal composite plate preparation. The process comprises the following steps: taking at least one compound plate, and pre-rolling one surface of the compound plate into a first corrugated surface to form a corrugated compound plate; taking a base plate, and stacking the base plate with the first corrugated surface of the corrugated composite plate to form a metal composite plate blank; rough rolling is conducted on the metal composite plate blank, the plane of the corrugated composite plate is rolled into a second corrugated face, the corrugated metal composite plate is formed, and the corrugation direction of the second corrugated face is perpendicular to the corrugation direction of the first corrugated face; and the corrugated metal composite plate is subjected to finish rolling, and the metal composite plate with the interface being the crossed corrugated face is obtained. The one-way corrugations are rolled on the to-be-combined surface of the compound plate firstly, and then the metal composite blank is subjected to corrugation rolling, so that the elongation difference between the metal compound plate difficult to deform and the metal base plate easy to deform can be compensated, the problem of plate shape warping can be solved, meanwhile, the combination area between metal is increased, and the yield is improved. Fresh flowing metal is exposed in a larger range, and the bonding strength is improved.

Description

technical field [0001] The invention relates to the technical field of metal composite plate preparation, and more specifically, relates to a method for preparing a cross corrugated interface metal composite plate. Background technique [0002] Metal composite panels are composite materials made of two or more different metal materials through appropriate processing technology to achieve firm metallurgical bonding at the bonding interface. Metal composite panels combine the advantages of each component and make up for their respective deficiencies. They can improve the mechanical properties, thermoelectric properties, magnetism, formability, weldability, corrosion resistance and many other properties of the material. They are widely used in automobiles, machinery, ships, and metallurgy. , mining, aerospace, civilian products, petrochemical, energy, environmental protection equipment and chemical equipment and other fields. [0003] At present, the preparation methods of met...
