Factors and causes that influence the springback intensity in the case of conical draw parts made from steel sheets by using cylindrical and conical punches
Gheorghe BRABIE, Mioara RADU-COSTACHE
Abstract: The cold plastic forming of metal sheets generates an undesired phenomenon known as springback. Springback occurs after the tools removing and the forming forces become equal to zero – and leads to a shape and dimensions of the final part different from the theoretical ones. The study and analysis of the factors that influence this phenomenon is useful for the accurate design of the forming processes and forming tools. The present paper performs an analysis by simulation using ABAQUS software of the factors that influence the springback phenomenon in the case of conical drawn parts made from steel sheets by using cylindrical and conical punches.
Key words: springback, deep drawing, conical part
