A method for forming a metal sheet includes forming a metal sheet to have curved portions that are alternately continuous in a corrugated pattern and angled sidewall portions between top parts of adjoining curved portions by use of a pair of forming dies that are moved close to or away from each other. The forming includes bending the metal sheet by pressing a position corresponding to a boundary part between the top part and the sidewall portion of the metal sheet by a convex curved surface of the forming die by moving the pair of forming dies close to each other and thereafter forming the sidewall portions by compression.

Method and apparatus for forming metal sheet

A press die having a shaping face includes a holding frame, die members, a reference member, and a pressing bolt. Each of the die members includes a first surface that configures the shaping face. The die members are aligned in the holding frame. The reference member is arranged on an inner side surface of the holding frame to position the die members. The pressing bolt is supported by the holding frame on a side opposite to the reference member. The pressing bolt presses the die members against the reference member.
