Abstract

The forging process is characterized by a low material loss and a positiv change in the grain texture in comparison to other manufacturing processes, but is limited by the degree of component complexity. The application of multi-axial forging offers the possibility of producing more complex components while retaining the advantages. The special feature of multi-directional forging is, that the forming of the workpiece happens from different directions in the same processing step. The use of aluminum and brass as a forging material is particularly interesting because of their diverse technical use and their low oxide-scale formation. This thesis deals with the feasibility of multi-axial forging of aluminum and brass components. Based on a concept study of a selected component, the possibility, problems and limitations of the technology are shown. The forming process is simulated using the finite element method by using the software Simufact Forming. As a test component, a geometrically complex swing arm of a motorcycle with the test materials EN-AW-6082 and EN-AW 7075 is selected. In a basic study, the necessary forming parameters are found based on the simulation. This is done by optimizing the preform, tool design and process control. The tool loading, the required forces and the effects of the multiaxiality of the aluminum alloy component can be evaluated by means of a parameter study. The results can then be used as an aid for the conception of a forging plant.
