Description

Technical Field

[0002] Copper-aluminum-titanium explosive composite plate is a metal composite plate that is made by combining copper, aluminum and titanium plates through explosive welding technology. Specifically, this composite plate is made by explosive welding of five layers of metal steel plates: H62 brass plate, 1060 aluminum plate, T2 copper plate, TA2 titanium plate and Q345R. During the explosive welding process, the huge energy generated by the explosives is used to instantly weld different metal plates together, thereby achieving metallurgical bonding between different metal plates.

[0003] After searching the existing published documents, the utility model patent of Chinese patent publication number CN215243381U discloses a three-layer explosion composite plate of copper, titanium and aluminum. When splicing the existing explosion composite plates of copper, titanium and aluminum, the efficiency of side insertion is too low, and the top insertion cannot ensure the stability of the composite plate during explosion, which will reduce the processing efficiency of the composite plate and affect the installation efficiency of the multi-layer composite plate; the patent mainly uses the first installation groove of the inclined structure opened on the copper plate to tilt and push the first installation block of the same inclined structure for installation, thereby effectively completing the rapid installation between the copper plate and the titanium plate, and the inclined first installation groove and the first installation block are mutually engaged, which can ensure the stability of the composite plate during explosion; the composite plate also has the following defects;

[0004] During the explosive bonding process of the composite plate, since the copper, aluminum and titanium layers are positioned vertically but not horizontally, a lateral offset will occur when the copper, aluminum and titanium layers explode, which will cause a certain lateral offset and dislocation of the copper, aluminum and titanium after the explosion, making it difficult to perform neat explosive bonding. For this reason, the present application provides a copper-aluminum-titanium explosion composite plate. Utility Model Content
