Abstract

The invention relates to the field of metal molding, in particular to a high rib aluminum alloy wallboard manufacturing method. Firstly, upper and lower multipoint molds are adopted to oppositely press an aluminum alloy plane thick plate to mold a needed curved surface shape; and then, a high-speed milling method is used for milling a needed rib structure on the curved surface thick plate in a processing path parallel to the curved surface, so that a designed high rib aluminum alloy wallboard is obtained. The method applies the characteristic of quick and adjustable reconstruction of profile surfaces of the multipoint molds, uses one set of multipoint molds for molding double-curvature aluminum alloy thick plate parts with different geometric shapes, different thicknesses and different materials, and can control the rebound in molding of the aluminum alloy thick plate through multiple times of correction so as to improve the molding precision; and the high rib aluminum alloy wallboard manufacturing method can obtain high-precision high rib aluminum alloy wallboard parts without damaging fiber structures of the aluminum alloy plate materials, guarantees the strength requirements of the wallboard parts, solves the technical difficulties in large aircraft manufacturing, and can be popularized and applied to manufacturing of such other parts as spacecrafts and rockets.

Description

technical field [0001] The invention relates to the field of metal shaping processing, specifically a method for manufacturing high-reinforced aluminum alloy wall panels. Background technique [0002] With the rapid development of the aerospace industry, people's requirements for the performance of modern aircraft continue to increase. High-reinforced aluminum alloy integral wall panels have been widely used in the aerospace field due to their light weight, good rigidity, and long fatigue life. At present, the main methods of integral wall panel forming are: gate pressure forming, aging creep forming, shot blasting and so on. Aging creep forming has special requirements for materials, and requires large autoclave equipment, long manufacturing cycle and high production cost; shot peening is limited by deformation amount and wall plate structure, and is suitable for forming wall plates with low ribs ; Brake forming has strong adaptability to product dimensions and low proces...
