摘要：
A die 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.
