[0002] Aluminum hyperbolic plates are a special type of building decoration material. They have a unique hyperbolic shape and can be used to create complex curved surface effects. Aluminum hyperbolic plates are usually used for exterior wall decoration, interior decoration, ceilings, etc. in high-end building projects and are favored because of their unique aesthetic properties and excellent processing performance.
[0003] Currently, when bending an aluminum plate into an aluminum hyperbolic plate, it is usually mechanically bent by mechanical equipment such as a hydraulic bending machine or a bending machine. That is, a flat aluminum plate is placed on the bending device, and under the action of pressure, the aluminum plate is deformed by force to produce a bend, thereby forming an aluminum hyperbolic plate. And on the bending device, there is a multi-point forming module composed of multiple independent forming units. These units can be independently pressurized as needed to form a complex hyperbolic shape. However, it is difficult for the existing device to perform supplementary pressure on the multi-point forming module during the processing, which easily leads to uneven pressure distribution and stress concentration in each forming unit, affecting the forming accuracy of the product.
[0004] Therefore, in view of the above problems, a multi-size bending device for aluminum hyperbolic plates that can perform supplementary pressure during the processing, make the pressure distribution uniform on each forming unit, reduce stress concentration, and improve the forming accuracy of the product has now been developed.
