摘要：
PROBLEM TO BE SOLVED: To provide a forming method and a forming apparatus of cup-shaped parts, by which the miniaturization of equipment is realized and lowering of strength in a corner part formed by a bottom surface part and a side wall part is prevented.
SOLUTION: When forming the cup-shaped parts 8, a die, a first punch, a drawing punch sleeve and a second punch are prepared and a drawing hole part, a reduced tube forming hole part and an ironing hole part are beforehand formed in the forming hole of the die. A preliminary side wall part 82A which is annularly erected is formed by holding a plate-shaped work 80 between the first punch and the second punch and performing drawing to the work 80 with the drawing punch sleeve and the drawing hole part. Next, reduced tube side-wall part 82B is formed by applying tube reduction forming to the preliminary wall part 82A with the first punch and the reduced tube forming hole part. After that, the cup-shaped parts 8 are obtained by forming the side wall part 82 by applying ironing to the reduced tube side-wall part 82B by the first punch and the ironing hole part.

要解决的问题：提供一种杯形部件的成形方法和成形装置，通过该方法实现设备的小型化，并且由底面部分和侧壁部分形成的角部分的强度降低 被阻止 解决方案：在形成杯形部件8时，准备模具，第一冲头，拉伸冲头套筒和第二冲头，并且预先制成拉出孔部分，还原管形成孔部分和熨烫孔部分 形成在模具的成形孔中。 通过在第一冲头和第二冲头之间保持板状工件80并且利用拉拔冲压套筒和拉出孔部分对工件80进行拉伸来形成环形竖起的初级侧壁部分82A。 接下来，通过利用第一冲头和还原管形成孔部对预备壁部82A进行管还原成形来形成还原管侧壁部82B。 之后，通过利用第一冲头和熨烫孔部对减压管侧壁部82B进行熨烫而形成侧壁部82来获得杯状部8。 版权所有（C）2006，JPO＆NCIPI
