The Methodology for Determining the Springback of Large Metal Stampings

摘要

In the stamping operation, springback causes geometrical inaccuracies and defects in final shape of metal stampings. This defect is actual problem in stamping production. Nowadays the detailed description of the springback is not clarified well regarding production of more complicated shape. To eliminate springback problem in stamping production there are methods, discovered and approved by advanced procedures. However applying these methods, particularly in drawing operations is much more complicated. The research describes theoretical analysis of springback phenomenon and possible experiments for the springback compensation. The research also describes analysis of springback using software for numerical simulation AutoFormplus R5 which is currently used to design the process of stamping production in company SKODA AUTO.
