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。
