Abstract

The invention discloses a skin forming process and equipment for a multi-curved-surface plate and the multi-curved-surface plate, and the skin forming process comprises the following steps: A1, arranging an annealed plate raw material on a basic model mold, and tensioning the plate raw material in all directions by taking the center of the basic model mold as the center, the periphery of the plate raw material is continuously in a full-tensioning state; a2, the basic model mold is lifted, and it is ensured that the plate raw materials are tightly attached to the basic model mold for the first time. According to the method, a plate covers a base mold prepared in advance, and the plate is forced to extend powerfully by applying external force to form a required curved surface shape. The finally formed plate is directly and only from the raw material, and the shape is obtained from the base mold, so that the product has a controllable shape even if multiple times of molding are carried out.

Description

Technical field [0001] The present invention relates to the technical field of multi-curved panel material, in particular to a multi-curved panel material skin forming process and equipment and multi-curved panel material. Background [0002] In order to form a multi-curved panel in the prior art, the following three technical solutions are generally used: [0003] (1) Using the malleability of the metal sheet, it is forced to extend and deform by means of forging or tapping. The problem with this solution is that product consistency is difficult to guarantee. [0004] (2) The metal surface is cut into a number of small unit pieces, spliced into the required curved shape, and then welded on the back of the splicing seam position, the interior and exterior are polished until the external surface is smooth and smooth and the gap is fused without marks, and then sprayed with the corresponding protective or finish coating according to the needs. The problem with this scheme is that ...
