    • 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).
    • 本发明提供一种压制构件的形成方法,压制构件的制造方法以及用于形成压制构件的模具装置,其能够降低形成所需的载荷,从而减小使用的设备的尺寸和复杂程度 用于形成按压部件。 通过压制具有锥形管状部分(91)的预成型件(90)和设置在管状部分的端部处并弯曲成圆弧的倾斜部分(92)来形成按压部件(90)。 通过包括保持体(110),穿刺冲头(120)和穿孔模具(130)的成型模具装置(100)进行压制。 在预成型体(90)的管状部(91)被保持体(110)的外侧固定支承部(112)保持的状态下,穿刺模具的内侧固定支承部(132) (130)中,成形模具装置(100)使用穿刺冲头(120)的外切割刃(122)和穿孔模具的内切割刃(135)切断一部分倾斜部分(92) 130),然后使穿刺冲头(120)的按压部(121)弯曲并在成形空间(FS)内按压倾斜部(92)的剩余部分,从而形成拐角部(83)。
