| description | PROBLEM TO BE SOLVED: To provide a press forming method by which spring back of both of "warpage" and "torsion" in a press-formed component having a curvature part curved along a component longitudinal direction can be reduced, and to provide the press-formed component formed by the press forming method.SOLUTION: The press forming method includes a press forming analysis step (S1) of performing press forming analysis by using fundamental shape data of a mold to obtain stress distributions of an outer flange part 7 and an inner flange part 11 at a bottom dead point and a press forming step (S2) of performing press forming in such a way that a step shape 19 is formed on a compression stress part C and/or a weak stress part N in the stress distributions obtained in the press forming analysis step.
【課題】部品長手方向に沿って湾曲する湾曲部を有するプレス成形部品に対して、「反り」と「捩り」の両方のスプリングバックを軽減できるプレス成形方法及び該プレス成形方法によって成形されたプレス成形部品を提供する。【解決手段】本発明に係るプレス成形方法は、基本となる金型の形状データを用いてプレス成形解析を行い、下死点における外側フランジ部７と内側フランジ部１１の応力分布を取得するプレス成形解析工程（Ｓ１）と、該プレス成形解析工程で取得した応力分布において、圧縮応力部Ｃ及び／又は弱応力部Ｎにステップ形状１９が形成されるようにプレス成形を行うプレス成形工程（Ｓ２）とを備えたことを特徴とするものである。【選択図】 図１ |
