Abstract: A piercing die, a holding body, and a piercing punch are used to form a pressed component having a plate-shaped base portion and a tubular boss portion extending from the base portion. The piercing die has a receiving portion, an outer shape-forming portion, and a die-side cutting edge. The piercing punch has an inner shape-forming portion, a punch-side cutting edge, and a straight portion. In a process of forming a pressed component, the piercing punch is pressed against a preform which is formed from a blank and which has a preliminary boss portion so as to cause part of the preliminary boss portion to flow toward the outer shape-forming portion, and so as to then cut off another part of the preliminary boss portion to form a boss portion.

Abstract: The present invention provides a method for forming a pressed metal component, a method for manufacturing such a pressed component, and a die apparatus for forming such a pressed component which decrease the size and the degree of complexity of equipment used for forming a pressed metal component having a plate-shaped base portion and a tubular boss portion extending from the base portion and allow formation of the boss portion in a wide variety of shapes. A piercing die 110, a holding body 120, and a piercing punch 130 are used to form a pressed component 90. The piercing die 110 has a receiving portion 111, an outer shape-forming portion 112, and a die-side cutting edge 113. The piercing punch 130 has an inner shape-forming portion 131, a punch-side cutting edge 132, and a straight portion 133. In a process of forming the pressed component 90, the piercing punch 130 is pressed against a preform 90′ formed from a blank BL and having a preliminary boss portion 92′ so as to cause part of the preliminary boss portion 92′ to flow toward the outer shape-forming portion 112, and so as to then cut off another part of the preliminary boss portion 92′ to thereby form a boss portion 92.

Abstract translation: 本发明提供一种形成压制金属部件的方法，这种压制部件的制造方法以及用于形成这种压制部件的模具装置，其减小了用于形成压制金属部件的设备的尺寸和复杂程度 具有板形基部和从基部延伸的管状凸台部，并允许以各种形状形成凸台部。 穿孔模具110，保持体120和穿孔冲头130用于形成被按压部件90.穿刺模具110具有容纳部分111，外形成部分112和模具侧切割刃113 穿孔冲头130具有内部形状形成部分131，冲头侧切割边缘132和直线部分133.在形成压制部件90的过程中，穿孔冲头130被压在形成的预成型件90'上 从坯料BL起，具有预备凸台部92'，使预备凸台部92'的一部分朝向外形形成部112流动，然后切断预备凸台部92的另一部分 从而形成凸起部分92。
