METHOD FOR MANUFACTURING AUTOMOBILE OUTER PLATE PANEL HAVING CONCAVE PORTION, AND PRESS MOLDING DEVICE

摘要

To stably restrict formation of surface strain around a concave portion, while suppressing costs, in manufacturing an automobile outer plate panel having a concave portion, and thereby solve the problem of prior art that it has been difficult to stably restrict surface strain, while suppressing costs, in manufacturing an automobile outer plate panel, such as a door outer panel having a concave portion.SOLUTION: In manufacturing an automobile outer plate panel having a concave portion, the concave portion is formed under vibration of a die. The concave portion is a concave embossment or a portion interposed between adjacent character lines.SELECTED DRAWING: Figure 2
