An influence of some process parameters on lateral forces in forging dies

abstractEN: The lateral forces are relatively high in production of nonsymmetrical or extended forgings what results in an offset of the upper and lower dies. Two industrial forging processes for the bracket lever and the valve lever were analyzed. MSC/SuperForge software based on finite yolume method has been used in numerical modeling of the processes. Combined thermo-mechanical numerical analysis took into account all stages of the forging processes. Changes in the inclination of parting line of dies and geometry of preforms resulted in considerable changes in distribution of force components. The results of calculations have been very helpful in finding the process parameters for which the lateral forces were relatively Iowscore:
