A die apparatus for forming a press-formed component includes a piercing die, a piercing punch, and a support. The piercing die includes a tubular first forming portion for forming a boss portion and a second forming portion having a cutting edge and an inwardly extending portion. The second forming portion is adapted to perform pressing of a preform while cutting a portion thereof. A cutting edge which cooperates with the cutting edge of the second forming portion is formed at a distal end of the piercing punch. When forming a press-formed component, a projection end portion of a preform formed from a blank by drawing is cut and removed by the two cutting edges, and a preform boss portion is then pressed and swaged by the inwardly extending portion.

Method of shaping a component

A method of shaping a component includes providing a plurality of work-piece blanks. The method also includes generating a contour in each work-piece blank, such that each contour is bordered by a region of material of the respective work-piece blank. The method also includes stacking the work-piece blanks such that the contour of one work-piece blank is aligned with the contours of the other blanks. The method additionally includes simultaneously annealing the region of material bordering the respective contour of each stacked work-piece blank to thereby enhance formability of the region of material. Furthermore, the method includes forming a shape in at least one of the work-piece blanks via stretching the annealed region of material bordering the respective contour to thereby shape at least one component. The component can be a structural reinforcement for a vehicle.
