Abstract:
Hole flanging, widely used in the automotive industry, is one of the most important processes in the sheet metal forming. Sometimes, in this process cracks occur at the initial hole edge. In this study, numerical simulations have been used to analyze the hole flanging of circular plates with a pre-determined initial hole at the center of sheet metal. Necessary data on mechanical properties of the workpiece material (St 14 according to DIN standard) for process modeling were determinated by an experiment. According to obtained results, a model of the hole flanging process for single sheet metal thickness was defined. Numerical simulation results include dependency between the maximum punch load and punch stroke for different hole diameters.
