Abstract

The frictional characteristics of galvanized sheet steels(GA, EG, EGF, EGN) for automobiles were studied and compared with that of cold rolled sheet steel. A draw bead tester which simulates metal flow through a draw bead in stamping die face was used to measure coefficients of friction of galvanized sheet steels for four kinds of lubricants. Stamping formability of galvanized sheet steels for quarter outer panel was examined. The results show that stamping formability and friction characteristics were mainly influenced by the nature of zinc coating, surface roughness and micro hardness of coated layer, and proved to be very sensitive to the lubricant used.

본 연구에서는 자동차용 표면처리 강판의 스탬핑 성형에 있어서 도금 종류별 도금층의 표면특성과 마찰, 윤활특성의 상관관계를 규명하고, 스탬핑 성형특성을 파악 하여 도금 종류별 최적 성형조건을 도출하고자 한다.
