Abstract
In a forming press, a blank is pressed formed into a press-formed workpiece by means of an upper die and a lower die, while a peripheral edge portion of the blank is clamped by means of a die and a blank holder insert of the forming press. Subsequently, a central portion of the press-formed workpiece is partially held by means of the upper die and the lower die so as to draw a peripheral portion of the press-formed workpiece away from the central portion thereof, thereby removing strain from the press-formed workpiece.
