Title:
METAL PLATE FORMING METHOD, INTERMEDIATE SHAPE DESIGNING METHOD, METAL PLATE FORMING MOLD, COMPUTER PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/123989
Kind Code:
A1
Abstract:
Upon forming a metal plate into a molded shape, this metal plate forming method forms a metal plate into an intermediate shape, and then forms the metal plate into a molded shape through press molding. When forming the metal plate into the intermediate shape, the intermediate shape is formed by forming a first area that includes at least a part of a portion where the reduction rate of the plate thickness with respect to the metal plate is greater when the metal plate is being formed into the molded shape via the intermediate shape as compared to when the metal plate is being directly formed into the molded shape.
