Design and Analysis of Deep Drawing Process on angular Deep Drawing Dies for Different Anisotropic Materials

Abstract

Deep drawing process is a significant metal forming process used in the sheet metal forming operations. From this process, complex shapes can be manufactured with fewer defects. Deep drawing process has different effectible process parameters from which an optimum level of parameters can be identified so that an efficient final product with required mechanical properties will be obtained. The present work is to evaluate the formability of different metal sheets using deep drawing process. In which effects of different sheets and die/blank holder angle on deep drawing process observed for sheet metal of 0.8mm of SS304 and Brass and 0.9 mm of Al. The experiments were performed by designing the deep drawing tools such as die, blank holder, and punch. In addition, the numerical simulations are performed for deep drawing of cylindrical cups using three levels of previously mentioned. Punch forces and dome heights are evaluated for all the conditions. From this work, the formability for different metal sheets is observed for angular geometries of deep drawing tools. Moreover, it is observed that strain formation is more for the brass sheet and stress is more for aluminium sheets.
