Description

Technical Field

[0001] The invention relates to the technical field of aluminum veneer processing, and in particular to a high-strength compression-resistant aluminum veneer and a production process thereof. Background Art

[0002] Aluminum veneer is a common building decoration material. It is light, easy to install, and decorative. It is widely used in the decoration of building exterior walls. Aluminum veneer is green and environmentally friendly. It is a recyclable product and is beneficial to the environment.

[0003] The existing aluminum veneer has a small overall area and a simple shape, which is not beautiful enough and cannot meet people's demand for beautiful exterior wall shapes. In order to improve the aesthetics of some building decorations, some curved aluminum veneers are manufactured, but the curved aluminum veneer has relatively poor bearing capacity. Due to its thinness, it has low strength. When it is locally stressed, it leaves obvious dents on the surface of the aluminum veneer, which affects the decorative beauty of the aluminum veneer. At the same time, in the manufacturing process of the aluminum veneer, it is necessary to laser weld the positioning curved plates on both sides of the aluminum veneer to maintain the curvature of the aluminum veneer to position and fix it. At present, for this kind of arc welding, a manual handheld laser welding gun is usually used to perform laser welding on the positioning curved plates, and the welding efficiency is low. At the same time, during the welding process, the positioning curved plates will undergo elastic deformation, which makes it easy for the curved aluminum veneer and the positioning curved plates to be misaligned, resulting in poor welding effect.
