Embodiment 1

[0032] refer to Figure 1-3 , 5, 6, a kind of cold-rolling method of preparing Cu / Al bimetal clad plate, comprises the following steps:

[0033] S1. Blank making: select pure Al plate as substrate 1, with length, width, and height of 50mm, 50mm, and 3mm respectively, and select pure Cu plate as double plate 2, with length, width, and height of 50mm, 50mm, and 1mm, respectively. The deformation resistance of Al plate is relatively high. Small, the deformation resistance of the Cu plate is relatively large, the ratio of the thickness of the base plate 1 to the double plate 2 is 3, and the double plate 2 is stacked on the top of the base plate 1, symmetrically at a distance of 25mm in the width direction of the rolled bite end. Drilling two holes and riveting them with rivets can ensure that the component plates of the bimetallic composite slab 3 can be bitten into the rolls synchronously to obtain the bimetallic composite slab 3 . In this embodiment, the thickness ratio of the ...

Embodiment 2

[0039] refer to figure 1 , 2 , 4-6, a kind of warm rolling method for preparing Mg / Al bimetal clad plate, comprises the following steps:

[0040] S1. Blank making: choose 5052 grade aluminum alloy plate as the substrate 1, the length, width and height are 50mm, 50mm, 3mm respectively, choose AZ31 grade magnesium alloy plate as the double board 2, the length, width and height are 50mm, 50mm, 1mm, respectively, 5052 grade The deformation resistance of the aluminum alloy plate is small, and the deformation resistance of the AZ31 magnesium alloy plate is relatively large. The ratio of the thickness of the substrate 1 to the double plate 2 is 3. The double plate 2 is stacked on the top of the base plate 1. Two holes are symmetrically drilled at a distance of 25mm in the width direction of the entry end and riveted with rivets to obtain a bimetallic composite panel slab 3 . In this embodiment, the thickness ratio of the substrate 1 and the doubler board 2 is 3, and in other embodi...

Abstract

The invention relates to the technical field of preparation of a bimetallic composite plate, in particular to a method for strongly deforming and rolling a bimetallic composite plate, and aims to solve the technical problems of low bonding strength, large residual stress and serious warpage in an existing bimetallic plate rolling method. According to the technical scheme, a manufactured bimetalliccomposite plate blank is subjected to two passes of rolling, a wave plate rolling mill is adopted for the first pass, the upper roller is a crossed corrugated roller, and the lower roller is a flat roller; and a flat roller mill is adopted for the second pass, and the upper roller and the lower roller are all flat rollers. According to the rolling method, the composite plate with good comprehensive performance of the tensile shear strength and tensile strength in the rolling direction and the transverse direction is obtained, and the residual stress distribution inside the bimetallic composite board can be obviously improved; and by adopting the novel process for rolling the bimetallic composite plate, the bonding strength of the two plates can be improved, the residual stress distribution state is improved, and the plate warpage is reduced.

Description

technical field [0001] The invention relates to the technical field of bimetal composite plate preparation, in particular to a method for strongly deforming and rolling a bimetal composite plate. Background technique [0002] With the advancement of science and technology and the emergence of new technologies and new industries, especially the rapid rise and development of high-tech, sophisticated and cutting-edge technologies, the demand for engineering materials in various countries in the world is becoming more and more extensive, and more and more requirements have been put forward for the performance of materials. demanding. Therefore, through specific methods and technologies, two or more metal sheets with different physical, chemical and mechanical properties are solid-state composited to make full use of the advantages of each component to create a new layered metal composite material, which has become a new technical approach. [0003] Bimetal composite panel is a...
