Research on the Effects of Hot Stamping Process Parameters on Mechanical Property for U-Shape Part

Abstract:

For the sake of research on the hot stamping property of high strength steel, the stamping forming of USIBOR1500P is simulated by the nonlinear finite element software Dynaform and Ansys/ls-dyna. The initial data simulated on USIBOR1500P is obtained by the hot tensile test. The simulation results show that the martensite weight percentage and Vickers hardness are in inverse proportion to stamping speed and initial die temperature. Otherwise, they are increased when the heat conduction coefficient is rising. Thus they affect the final properties of machinery of U-shape part. The maximum stress appears in the die and punch radius, and the minimum stress appears in the flange and the bottom of the blank. The minimum temperature value appears in the flange and the maximum temperature value appears in the die and punch radius.
