Die Forging Process Simulation of a Connecting Rod

Article Preview

Abstract:

Numerical simulation of connecting rod die forging processing was performed by finite element method (FEM) software Deform 3D. The changes of the temperature fields, stress fields of the billet and dies, and upper setting force-stroke curve during the die forging were obtained. The simulation results show that (1) the increase of the fillet radius of dies could effectively reduce the stress concentration so that to prevent the die crack arising at high level stress; (2) the optimum parameters of die forging process are 430°C for forging temperature, 200°C for preheat temperature of dies and 80mm/s for reduction rate by comparing both fields of the stress and temperature during different forging process..
