Abstract

This paper deals with the methodology for developing a laboratory inverse redrawing device. The drawing process is performed in two phases: a direct drawing of a circular blank followed by a second reverse re-drawing phase on the same device. Finite element simulations are carried out in order to i).define geometrical characteristics of the modular re-drawing device and to ii). estimate the punch force evolution for different dimensions of punch, die and blankholder and for a large class of materials. Based on such FEM simulations, springs for the developed reverse deep drawing device are dimensioned. The use of springs gives the possibility to deform the material with an imposed blank-holder force. Finally, a draw of the designed modular device is presented considering all the results of the finite element simulation.
