Experimental Laboratory Tooling for Deep Drawing Process

New trends in the deep drawing of tailored blanks demands for the analysis of process parameters and their setup to obtain the drawn parts with required shape precision, strength and stiffness. One option is to perform the experiments, measurements and optimization of that process on an experimental laboratory device and to compare the results to those from simulations. This contribution deals with the redesign of a device that is used at the Institute of technologies and materials with regard to replacement of strain gauge force measuring system by piezoelectric force measuring system. The new design is also focused on a new way of setting the blankholder pressure applied on the tailored blank.
