Title:
METHOD FOR FORMING CURVED SURFACE OF THICK ALUMINUM PLATE HAVING THREE-DIMENSIONAL CURVATURE
Document Type and Number:
WIPO Patent Application WO/2014/003231
Kind Code:
A1
Abstract:
The present invention relates to a method for forming a curved surface of a thick aluminum plate, and more specifically, to a method for forming a curved surface of a thick aluminum plate, which reduces the elastic recovery. The method for forming a curved surface of a thick aluminum plate, according to the present invention, comprises: a first forming step in which a thick aluminum plate, made by bonding a plurality of plates of which the principal material is aluminum, is formed to have a curvature in the opposite direction of the target curvature; a second forming step in which the thick aluminum plate is formed preliminarily to have a curvature smaller than and in the same direction as the target curvature; and a third forming step in which the thick aluminum plate is formed to have the target curvature. The present invention can make it easier to form a curved surface of a thick aluminum plate, thus enabling the manufacturing of formed bodies of various shapes which have curved surfaces, using thick aluminum plates.
