Uticaj sile držanja i stanja površina na duboko izvlačenje „tailored blanks”

Abstract

During the deep drawing of tailored blanks, tribological conditions make an influence on a forming process in a very complex way. The blank holding force and contact surfaces state of tools and materials are important parameters, which the final parameters of a deep drawing process depend on. In the paper the results of experimental analysis of deep drawing of tailored blanks and basic blanks they were made of, were shown. The influences of the different blank holding forces and different tribologic conditions were investigated, using the main deformations distributions and the deep drawing force change during the process.
