Embodiment 1

[0062] Attached figure 1 , 2 The method shown prepares copper-aluminum composite panel:

[0063] 1) Blank: Select pure aluminum plate as cladding plate 1, the plate size is 200mm (length) × 50mm (width) × 2mm (height), pure copper plate is used as substrate 2, plate size is 200mm (length) × 50mm (width) × 8mm (high). Use a grinding tool equipped with a wire brush to grind the surface of the pure copper plate and the pure aluminum plate to the effect of "sand surface" to remove the oxide on the surface of the slab and create favorable conditions for copper-aluminum compounding, and then polish the copper and aluminum plates. Stacking, and riveting the head and tail of the plates to ensure smooth and synchronous biting of the base and compound plates, and no deviation during the rolling process, to obtain the composite plate blank 3.

[0064] 2) Rolling: use a two-roll mill with the upper roll as a corrugated roll and the lower roll as an ordinary flat roll for rolling, and f...

Embodiment 2

[0073] Attached figure 1 , 2 Prepare carbon steel-stainless steel clad plate by the method shown:

[0074] 1) Blank, select s316L plate as cladding plate 1, the plate size is 200mm (length) × 50mm (width) × 2mm (height), Q345R carbon steel plate is used as base plate 2, plate size is 200mm (length) × 50mm (width) ×8mm (height). Use a grinding tool equipped with a wire brush to grind the bonded surface of the pure copper plate and the pure aluminum plate after stress relief annealing to the effect of “sand surface” to remove oxides on the surface of the slab and create favorable conditions for the compounding of carbon steel and stainless steel , then stack the polished surfaces of carbon steel and stainless steel plates, weld the carbon steel and stainless steel around, and weld a vacuum tube at the interface of the blank head to be bonded, and use a vacuum pump to vacuum the blank to prevent the bonding interface More oxidation occurs during the heating process, and the co...

Abstract

The invention belongs to the technical field of material machining of metal composite boards, particularly relates to a continuous laminating and rolling method for a corrugated interface double-metalcomposite board. The method is characterized in that blanks are rolled into corrugated composite boards by adopting a corrugated roller, the stress peak value is formed at wave troughs of the composite boards, and the combination of the wave troughs is promoted, rolling is carried out by adopting a flat roller, then the stress peak value is formed at the wave crests of the corrugated composite boards so that the relatively high strength combination is realized at the wave peaks, and the high-strength combination of the composite board from the local to the whole surface can be realized by utilizing the two stress peaks at different positions. The extension of metal in the rolling process of the corrugated composite board is mainly achieved through downward pressing of the metal at the position of the wave crests, flowing of the metal at the wave troughs is very small, so that the wave troughs of the corrugated composite boards are not prone to breakage in the flattening process, moreover, the downward pressing of the metal at the wave crest applies a reverse extrusion stress to the wave trough of the composite board at the other side, then the bonding strength at the original wavetrough is further improved, and the double-metal composite board with the good board shape is obtained.

Description

technical field [0001] The invention belongs to the technical field of material processing of metal composite plates, and in particular relates to a method for continuous stacking and rolling of corrugated interface bimetallic composite plates. Background technique [0002] In the past century, with the rapid development of science and technology, especially the rise of high-precision technology, the limitations of a single metal have become increasingly prominent in terms of resource consumption, cost, and material use and performance. Many fields cannot meet the needs of modern industrial production and high-tech development. In order to comply with the historical trend and the needs of social development, composite materials have officially entered the stage of history. [0003] Double composite board is a kind of composite material. Because it has the advantages of two kinds of metals, it is widely used in aerospace, weapon manufacturing, home appliances and other field...
