Abstract

Within the scope of the subproject “Dynamic Process Forces” of the Collaborative Research Centre TCRC 73, a sheet-bulk metal forming (SBMF) process was developed to produce a demonstrator component with internal and external gearing from a sheet metal blank in three production steps. In the first step, a cup is deep-drawn. A hole is shear-cut in the centre of the cup and the cup frame is displaced into a tooth cavity by a compression punch so that the external gearing is formed. In a subsequent second step, an internal gearing is formed by an upsetting punch. A recalibration of the internal gearing takes place in a third process step. In the course of the project, methods for a better control of the material flow and for increasing component quality are investigated in order to extend the limits of sheet-bulk metal forming. These methods include the installation of superimposed oscillation in the main force flow of the forming machine and the use of structured and coated tools, the so-called tailored surfaces.
