자동차용 부품의 제조 방법은, 금속 재료, 또는 금속과 수지를 포함하는 복합 재료에 의하여 형성된 중공관의 일부를 프레스 가공에 의하여 관 외측으로부터 관 내측으로 상기 중공관의 축심을 넘어 변형시켜, 상기 중공관의 일부가 오목상으로 변형된 변형부를 성형하는 성형 공정과, 상기 변형부가 구성하는 폐단면 중, 잔류 응력이 높은 부위를 면 외 변형시키는, 변형 공정을 구비한다.
An automotive component manufacturing method includes a molding process of pressing a portion of a hollow tube formed from a metal material, or a composite material including a metal and a resin, so as to deform the portion of the hollow tube, from a tube outer side toward a tube inner side, to beyond an axial center of the hollow tube, and mold the portion of the hollow tube into a deformed section deformed with a concave profile; and a deformation process of deforming a location having a high level of residual stress in a closed cross-section configured by the deformed section so as to deform the location out-of-plane.
