Method for forming a pressed component

A method for forming a pressed metal component having a tubular body, one end of which is bent inward to form a cup-like shape, the method comprising:

• preparing a preform having a tubular portion and a sloping portion which is provided at an end of the tubular portion and which slopes with respect to the tubular portion;
• preparing a piercing punch which is disposed outside the sloping portion of the preform and which has an outer cutting edge for cutting off a portion of the sloping portion of the preform and a pressing portion for pressing the remaining portion of the sloping portion;
• preparing a piercing die which is disposed inside the sloping portion of the preform and which has an inner cutting edge for cutting off the portion of the sloping portion in cooperation with the outer cutting edge, a receiving portion for receiving the sloping portion pressed by the pressing portion within a forming space between the receiving portion and the sloping portion, an inner extension restricting portion for restricting lengthwise extension of the sloping portion pressed by the pressing portion, and an inner fixing and supporting portion for fixedly supporting the tubular portion;
• preparing a holding body which is disposed outside the sloping portion of the preform and which has an outer extension restricting portion for restricting lengthwise extension of the sloping portion pressed by the pressing portion and an outer fixing and supporting portion for fixedly supporting the sloping portion;
• and
• causing the piercing punch and the piercing die to move relative to each other in a state in which the preform is fixedly supported by the piercing die and the holding body so as to cut off the portion of the sloping portion and bend and press the remaining portion of the sloping portion to form a corner portion.
