Aiming at the die wear problem of ultra high strength steel stamping forming, an effective and fast method was proposed for predicting die wear and working life. The method adopted Archard wear theory in order to obtain mould wear data after stamping forming. Die wear was mainly concentrated in the die round corners. The factors affecting die wear were analyzed systematically. These factors include die hardness, stamping speed and die material. The results showed that the die wear decreased effectively when the die hardness reached 60~65 HRC. The die wear was positively correlated with the stamping speed. Wear cumulation method was used to predict the service life of die， which had stamped 7500 times. the difference between die wear calculated by simulation and test data was only 1.47%, which showed that the method was feasible. The method has an important practical value in determining reasonable stamping process and designing die structure.
