ABSTRACT:
Method and apparatus for pressing a sheet blank into a tubular container, including a first process or device for drawing the blank into an intermediate workpiece having a tubular portion and a bottom portion closing one end of the tubular portion, and a second process or device for ironing the tubular portion in the axial direction. The second process includes a forward ironing step for placing the workpiece on a first ironing punch and forcing the workpiece and first punch together into a first die hole, to iron the tubular portion in an axial direction from the above one end toward the other end, and a backward ironing step for placing the workpiece on a columnar second ironing punch and forcing the workpiece and second punch together into a second die hole, with a columnar pushing punch held in pressing contact with the outer surface of the bottom portion of the workpiece, to iron the tubular portion in the direction opposite to that in the forward ironing step.
