FACTORS AND CAUSES THAT INFLUENCE THE SPRINGBACK INTENSITY IN THE CASE OF DRAW PARTS MADE FROM METAL SHEETS
Gheorghe BRABIE, Neculai NANU
Abstract: Drawing of the sheet metal parts is always accompanied by an undesired phenomenon known as springback. Springback occurs after the part is set free of the constraints – forming forces, tools – and leads to a shape of the final part different from the nominal ones. The knowledge 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 of the factors that influence the springback phenomenon in the case of conical and hemispherical drawn parts made from metal sheets.
Key words: springback, drawing processes and tools.
