Analysis of Multiple Open Hot Die Forging for a General Cylinder Based on Numerical Simulation

Numerical simulation of the die for cylinder upsetting is done by Marc AutoForge software on base of elastic-plastic theoretical mechanical model to analyze transient temperature field, equivalent total strain field and thermal strain field. Then qualitative and quantitative relationship is found between these Factors and die-damage. A new method-Heat Exchange Balance Method is put forward to solve the cooling problems of hot -forging die by combinating with production practice , research practice and using basic theory of finite element and thermal.
