In modern press shops, the latest press technology is used to meet today´s efficiency requirements of sheet metal body part production. Thus, for example, servomechanical press ram drives enable optimized process control through configurable motion profiles of the ram, resulting in increased stroke rates and output of the press line. However, the acceleration of moving masses arising during post-forming operations of line dies can lead to critical loads for the upper die and press ram drive. Especially the part holder of line dies causes dynamic loads when being accelerated during the return stroke. In this regard, this paper deals with the validation of dynamic part holder models on the basis of experimental data obtained by a prototype tool. Finally, design specifications could be defined using the validated dynamic models, enabling the process windows of line dies to be extended in future for robust high-speed production processes in modern press shops.
