| Abstract Scope |
This paper presents an engineering procedure for stamping irregular sheet metal parts with an elastic blankholder providing a localized contact pressure to ensure stamped parts without failures of cracks and wrinkles. This is done by arranging the height of the blankholder supporting elements in a die set, which is made by standard manufacturing quality and implemented in a press line equipped with standard die cushion. However, the contact pressure is very sensitive to the height of supporting elements. To eliminate the inherent noise from the GD&T of the die set, a finite element model for optimization of the contact pressure must be created according to the actual die set geometry. In this study, the blankholder geometry for stamping a fender-like part was scanned by GOM-ATOS and the height of cylindrical supporting elements was realized by inserting feeler gauges between blankholder and them according to the outcomes of finite element analysis. |
