Description
In the area of tension between ecological and economic challenges, innovative processes are required in the field of production technology in order to be able to meet the increasing demands on new products. In this context, sheet-bulk metal forming represents a promising technology that combines the potentials of established sheet metal and bulk metal forming processes. The central challenges are mainly to ensure sufficient control of the locally varying biaxial and triaxial stress and strain states for the production of near-net-shape functional components. Against this background, the present work deepened and extended the understanding of the process with regard to the design and use of process-adapted semi-finished products in order to be able to increase the material flow control in accordance with the required component properties. As a basis for the investigations, the requirements-based design of a tool geometry to manufacture process-adapted semi-finished products was carried out using a numerical variant simulation, which was subsequently supplemented by a more efficient design approach. The central requirements include the avoidance of identified defect patterns on the externally toothed functional components, which are produced by the single-stage process combination of deep drawing and upsetting. The realisation of a sufficiently high material flow control is one of the basic prerequisites for the efficient production of defect-free functional components made of steel and aluminium alloys in sheet-bulk metal forming processes.
