    摘要： The present invention provides a method for forming a pressed component, a method for manufacturing a pressed component, and a die apparatus for forming a pressed component which can reduce the load necessary for forming to thereby decrease the size and the degree of complexity of equipment used for forming a pressed component. A pressed component (90) is formed by pressing a preform (90) having a tapered tubular portion (91) and a sloping portion (92) which is provided at an end of the tubular portion and curved in a circular arc. The pressing is performed by a forming die apparatus (100) including a holding body (110), a piercing punch (120), and a piercing die (130). In a state in which the tubular portion (91) of the preform (90) is held by an outer fixing and supporting portion (112) of the holding body (110) and an inner fixing and supporting portion (132) of the piercing die (130), the forming die apparatus (100) cuts off a portion of the sloping portion (92) using an outer cutting edge (122) of the piercing punch (120) and an inner cutting edge (135) of the piercing die (130) and then causes a pressing portion (121) of the piercing punch (120) to bend and press the remaining portion of the sloping portion (92) within a forming space (FS) to thereby form a corner portion (83).

    摘要： A process for bending on a press a metal sheet through a desired angle and an inner bend radius less than the thickness of the sheet, without causing damages such as cracking in a bend. According to this process, a metal sheet is first bent through an angle approximating a desired angle, with an inner bend radius being greater than the thickness of the metal sheet, and then the metal sheet thus bent is further bent through a desired angle, with the inner bend radius being less than the thickness of the metal sheet, and with the stretching of a material of the metal sheet on the outer side of the bend being suppressed.
