Title
(ZH) 冲压成形部件的制造方法以及冲压成形装置
Abstract
(ZH)
在冲压成形工序中,从390MPa以上的高张力钢板的坯料(300)获得冲压成形品,该冲压成形品具有至少包括槽底部(101)、棱线部(102)以及纵壁部(103)的剖面形状,且在长度方向的端部形成有包括沿着棱线部(102)的部分(106a)的朝外凸缘(106),其中,使坯料(300)的成形为槽底部(101)的部分中的至少位于长度方向端部的区域(300a)成为离开冲头顶部(201b)的状态,开始进行成形为棱线部(102)的部分的成形,之后,使区域(300a)接近冲头顶部(210b)。由此,在一并成形棱线部(102)与朝外凸缘(106)的部分(106a)时,由于在从冲压成形开始时到中途比较缓慢地进行成形,减少或防止了延伸凸缘裂纹的产生、褶皱的产生。
