Abstract

絞り深さの大小に係わらず、プレス成形品のコーナー部分で発生する割れやしわを低減するプレス成形用金型、および該金型を用いたプレス成形方法を提供する。凹部２ｂと凹部２ｂの周囲に形成されるしわ押さえ面２ａとを備えるダイ２と、凹部２ｂに対応する凸部３ａを備えるポンチ３と、しわ押さえ面２ａに対応するクッション面４ａを備えるブランクホルダー４と、を備え、しわ押さえ面２ａとクッション面４ａによって挟持部１４を形成し、挟持部１４によって材料部材５を挟持しつつプレス成形するプレス成形用金型１を用いる。プレス成形用金型１の挟持部１４は、凹部２ｂのコーナー凹部２ｃに連通する開放部１５によって、第一挟持部１４ａと第二挟持部１４ｂとに分断され、第一挟持部１４ａと第二挟持部１４ｂとによって材料部材５を挟持する。
