A Study on Cold Forming of Curved Thick Plate by Reconfigurable Multi-Punch Dies
다점 펀치를 이용한 조선용 곡판 냉간 성형 방법 연구
Abstract
Curved thick plate forming in shipbuilding industry is currently performed by a thermal process, called as Line Heating by using gas flame torches. It was examined as an alternative way in this study to manufacture curved thick plates by the multi-punch die forming. Experiments and finite element analyses were conducted to evaluate the feasibility of the reconfigurable discrete die forming to the thick plates. Configuration of the multi-punch dies suitable for multi-curvature was investigated. As a result, single step forming by reconfigurable discrete die with scale factor improved formability.
