Hat-shaped cross-section component manufacturing apparatus

A hat-shaped cross-section component manufacturing apparatus comprising:

• a die that includes a forming face that presses both side portions of a metal sheet, and that includes an opening disposed between both side portions of the forming face of the die;
• a punch that is disposed facing the opening of the die, wherein the punch is disposed inside the opening when a mold is closed, and wherein the punch includes a forming face that presses a central portion of the metal sheet;
• a pad that is disposed inside the opening formed in the die, wherein the pad includes a forming face that presses and grips the central portion of the metal sheet against the punch when the mold is closed so as to configure a forming face corresponding to the forming face of the punch;
• a holder that is disposed facing the die, wherein the holder includes a forming face that presses and grips both side portions of the metal sheet against the die when the mold is closed so as to configure a forming face corresponding to the forming face of the die;
• and
• a pressure limiting device that limits a formed hat-shaped cross-section component with a hat-shaped cross-section profile from being pressed between the pad and the holder during demolding, wherein
• the pressure limiting device includes a coupling portion that fixes a positional relationship between the pad and the holder by coupling the pad and the holder together.
