Abstract

For the production of functionally integrated components made of sheet metal materials, the processes of Sheet-Bulk Metal Forming are suitable, which enable the production of planar components with local functional elements. Limitations in the die filling of the functional elements and high die loads are a result of the demanding forming and process conditions that occur within these processes. When transferring this process class to efficient production from coil, previous investigations also identified anisotropic material flow and anisotropic die loads as relevant process influences when carrying out extrusion processes from sheet coils.

Based on this, the influence of the component design on a multi-stage extrusion process from coil will be analyzed numerically and experimentally within the scope of this research project. In the first step, cause-effect relationships are to be investigated with regard to the local die filling of the functional elements and the local die load when the blank and coil geometry is varied. Furthermore, using these findings, the potential for controlling the material flow and thus improving die filling by adapting the possible stage sequences is to be derived.
