Title
(KO) 프레스 성형 부재의 제조 방법 및 프레스 성형 장치
Abstract
(KO)
390㎫ 이상의 고장력 강판의 블랭크(300)로부터, 홈저부(101), 능선부(102) 및 종벽부(103)를 적어도 갖는 단면 형상을 갖고, 길이 방향의 단부에, 능선부(102)를 따르는 부분(106a)을 포함하는 외향 플랜지(106)가 형성된 프레스 성형품을 얻는 프레스 성형 공정에 있어서, 블랭크(300)의 홈저부(101)에 성형되는 부분 중 적어도 길이 방향 단부에 있는 영역(300a)이 펀치 정상부(201b)로부터 이격된 상태가 되도록 하고, 능선부(102)에 성형되는 부분의 성형을 개시하고, 그때 이후에, 영역(300a)을 펀치 정상부(201b)에 접근시킨다. 이에 의해, 능선부(102)와, 그것에 맞추어 외향 플랜지(106)의 부분(106a)을 성형할 때에, 프레스 성형의 개시 시부터 도중까지는 비교적 완만하게 성형함으로써, 신장 플랜지 균열의 발생이나 주름의 발생을 저감 또는 방지한다.
