Analysis and application on model of press straightening process with FEM

Load-deflection model of press straightening process is explained. The method and procedures of establishing load-deflection model by using ANSYS software are described. Based on the model, the straightening stroke can be calculated, so it is solved to apply FEM to automatic straightening machine. An example is given, calculation results by FEM are in good agreement with the experimental results. The validity of the method is proved.
