冲压成型品的制造方法以及冲压模具
摘要：
一种冲压成型品的制造方法，使用具有冲头冲压成型品，该冲压成型品具有第一壁部(21)、从上述第一壁部的长边方向的至少一方侧的端部向上述第一壁部的背面侧延伸的第二壁部(23a、23b)、以及从上述第二壁部的前端部向上述第二壁部的表面侧延伸的第三壁部(25a、25b)，在该方法中，在以上述冲压模具的起模前的状态下的横截面观察时，通过上述冲头以及上述冲模将上述第二壁部的基端侧的部分加压夹持为向上述第二壁部的背面侧弯曲为凸的第一弯曲形状(23a-1、23b-1)。(31)以及冲模(32)的冲压模具(30A、30B)来制造
摘要（英）：

A method for manufacturing a press-molded article having a first wall section (21), second wall sections (23a, 23b) extended from the end part of at least one longitudinal-direction side of the first wall section to the rear-surface side of the first wall section, and third wall sections (25a, 25b) extended from the distal end part of the second wall sections to the front-surface side of the second wall sections, the press-molded article being manufactured using a press mold (30A, 30B) that has a punch (31) and a die (32); wherein portions of the proximal-end side of the second wall sections, as viewed in lateral cross-section in the state before the press mold has been separated, are pressed and sandwiched by the punch and the die into a first warp shape (23a-1, 23b-1) that warps in a convex shape toward the rear-surface side of the second wall sections.
