成形方法及び成形型
Document Type and Number:
Japanese Patent JP7358504
Kind Code:
B2
Abstract:
The purpose of the present invention is to suppress the generation of wrinkles during a bending process and to shorten the time period for lamination. A forming method according to the present disclosure comprises: a laminating step for forming an intermediate formed article (32) by supplying and laminating a fibrous sheet onto forming surfaces (22A, 22B) of a forming die (20) for forming the intermediate formed article (32); and a bending process step for performing a bending process on the intermediate formed article (32), which is laminated on the forming surfaces (22A, 22B) and has a shape that corresponds to the forming die (20), to yield a formed article. The forming surfaces (22A, 22B) have shapes that correspond to the intermediate formed article (32) to be formed. The second forming surface (22B) is bent with respect to the first forming surface (22A) among the forming surfaces (22A, 22B), and the angle formed by the first forming surface (22A) and the second forming surface (22B) is greater than the bending angle of the cross-section of the formed article to be formed and less than 180 degrees.
