PROBLEM TO BE SOLVED: To provide a punch press having an upward molding function by a die on a lower side of a work-piece.SOLUTION: Provided is the punch press for processing a work-piece by a punch and a die indexed and located at respective processing positions. The die D indexed and located at the processing position is declined to a lower position of a pass line PL of the work-piece and is held during movement of the work-piece and is pushed up to the pass line of the work-piece during processing by a die lifting mechanism 27. With respect to the die pushed up by the die lifting mechanism 27, force to displace by pressing displacement is applied more upward toward the punch for making the die mold the work-piece by an attachment cylinder (pressing mechanism) 110. The punch press comprises the die lifting mechanism 27 and the attachment cylinder 110. The attachment cylinder 110 is disposed as one of plural attachments which are selected according to the die and detachably disposed between an upper end of a lifting ram 65 and the die. |
