FEM-PROCESS-SIMULATION OF HYDROMECHANICAL DEEP-DRAWING

The FEM-Process-Simulation of metal forming processes has been proven to be useful during the design stage of components and toolings. However, this is not valid for relatively new processes, e. g.. hydromechanical deep-drawing. Hydromechanical deep-drawing is related to conventional deep-drawing, but the process is quite different. When using hydromechanical deep-drawing, instead of a rigid female die a counter pressure pot is used to form the sheet metal against the punch. The process modeling and application of conventional deep-drawing is a well-known process with a great amount of practical and theoretical experience. Therefore a large database of knowledge exists. In contrast to conventional deep- drawing, for hydromechanical deep-drawing the practical and theoretical knowledge is limited. Since the application of hydromechanical deep-drawing is becoming more interesting (e.g. for the production of niche cars), the demand of theoretical and practical knowledge is increasing
