Investigation on Influence Factors of Bulging of Boren Steel at Elevated Temperature

Abstract:

Article Preview

The finite element model of bulging at elevated temperature was established by using of pam-stamp 2007. The bulging tests of boron steel sheets were also performed on the self-designed and manufactured tool system. The simulated results of bulging height, limit strain and the minimum temperature of specimens are consistent with that of tests. It demonstrates the validity and accuracy of the finite element model established in pam-stamp. The influences of the friction coefficient, the temperature and the stamping velocity on the hot bulging are analyzed numerically. The friction condition should be improved and the minimum temperature gradient is recommended in practical hot stamping production.
