Numerical Simulation on the Shape of Stamping Part about Hot Forming and Quenching

Abstract:

With the application of ultra high strength steel in vehicle manufacturing field, the hot forming method which is used to form the high strength sheet at high temperature and cool rapidly in dies to obtain the final part has been studied extensively. In this paper, The FE model that contained thermal mechanical-microstructure and strain model represented by a mixture law for hot forming was discussed, and further been applied to hot forming and quenching process simulation of 22MnB5 metal sheet of U-shape constant section part. The computed results of final part shape and hardness after cooled in air, in water without dies and cooled within dies were compared respectively.
