Abstract

본 발명은 자동차의 도어 아웃터패널 성형방법에 관한 것으로, 종래 프레임 일체형 도어 아웃터패널 성형시 공정수가 많고, 이에 따른 설비부하 증대 및 불량발생, 다량의 스크랩으로 인한 원가상승의 문제점이 있었다.The present invention relates to a method of molding a door outer panel of an automobile, and conventionally, there are a large number of steps in forming a frame-integrated door outer panel, resulting in an increase in equipment load and defects, and a cost increase due to a large amount of scrap.

따라서 본 발명은 성형시 엘에치(LH)와 알에치(RH)도어 아웃터패널이 대향형성되는 도어 아웃터패널 금형에 의해 압출가공하는 드로잉 공정; 불필요한 부분을 제거하는 트리밍 공정; 그리고 보강 및 교정 다듬질을 위한 플랜징 및 리스트라이킹 동시공정을 통해 상기 엘에치(LH)와 알에치(RH) 도어 아웃터패널을 함께 성형토록 구성하여 설비부하 절감, 공정수 절감, 품질향상 및 원가절감을 이루고자 한것이다.Accordingly, the present invention provides a method of manufacturing a door, comprising: a drawing process for extruding a door outer panel mold having an eletric (LH) and an aluminum (RH) door outer panel opposed to each other; A trimming process for removing unnecessary portions; (LH) and Al etch (RH) door outer panel are formed together by the simultaneous process of flanging and restriking for reinforcement and corrective finishing to reduce facility load, We are trying to achieve cost reduction.
