Značaj deformacione analize pri ocenjivanju kvaliteta maziva za duboko izvlačenje

Abstract

The complete indicators in evaluation of technological qualities of lubricants for deep drawing take into account the realized stress-strain field during forming. Generally considered, the criteria are defined as well as the relevant parameters for reaching the forming limit, and in this paper they are specially applied for evaluation of influence of tribological conditions in contact between tool and thin sheet. The results are presented for very different drawing geometries, materials and forming conditions, where the presented methodology and obtained results can also be very usefully applied in manufacturing conditions.
