た。(Problems to be Solved by the Invention) However, in the past, the ridgeline portion of the corrugated workpiece W was simply pressed and deformed to form the flat portion WP, which caused various problems. That is, when forming the flat portion WP, the inclined surfaces on both sides of the ridgeline portion of the workpiece W are pressed and deformed to form the flat portion WP. Therefore, since the area of the plane part WP is smaller than the total area of the parts to be pressed and deformed on both sides before being formed on the plane part WP,
Wrinkles were likely to form around the flat part WP.

る。 As already understood, the ridgeline part of the work W
When forming WL on the plane part WP, 1 of the workpiece W
Since the part is pressed into the hole 13 of the die 3, the total area of the part formed in the flat part WP of the workpiece W is larger than the flat part WP, and the extra part that tends to wrinkle is the hole part. 13, thereby suppressing the formation of wrinkles.
前述のごとく、ワークＷに平面部WPを形成し
