Abstract
Complex forming parts that include functional elements can be produced by means of sheet-bulk metal forming within one process step. Adding functional elements to a workpiece design can lead to design asymmetry. As a result, horizontal forces appear during the forming process, leading to horizontal displacements of the press ram. Such displacements lead to process inaccuracies. In this report, the appearance of press ram displacements is discussed. Studies were carried out to determine the amplitude of possible displacements. The impact of horizontal forces on the manufactured workpiece quality was investigated. A numerical study that featured both, the manufacturing process as well as a multibody-model of the press has been conducted to increase the accuracy of the process simulation. In order to avoid horizontal displacements of the press ram, electromagnetic solenoids were designed and built. Experiments were carried out that show the increased process accuracy by compensating press ram displacements by means of counteracting forces. Additionally, a reduction of tool wear by superimposing horizontal oscillations to the forming process was detected in an experimental approach. A concept for a tool, which adds the horizontal degrees of freedom to the framework of the press bed, is presented as well.
