Abstract
Through a systematic analysis of the force-energy relationship of a clutch screw press during the forging process, the characteristics of the clutch screw press are defined and mathematical models of its force-energy relationship are established. On the basis of a commercial finite element software and the models developed, simulation of turbine disk IN718 forging is performed. The calculated results are compared with experiment data to validate the models. The results show that the proposed models can describe the kinematic properties and force-energy relationship of the press and predict accurately the deformation force and energy of forging and the strike force of the clutch screw press. Thus, the design of forging processes on this type of press and the quality control of forging may be implemented scientifically by the application of the proposed models.
