摘　　要：利用伺服压力机冲压成形系统的速度和压边力可调的特点,对DP1180高强度钢的胀形性能进行研究,获得了常温下0.8 mm厚的材料在不同的压边力、冲压速度及润滑条件下的IE值。试验结果表明:IE值随着压边力的增大呈现先增大后减小的趋势;随着冲压速度的增大,IE值逐渐增大;润滑条件对材料的胀形性能也有一定的影响,润滑条件越好,IE值逐渐增大。The bulging performance of DP1180 high strength steel was studied by using the characteristics of the speed and blank holder force adjustability of the servo press forming system.Through testing,the IE value of sheet with 0.8 mm thick was obtained under different stamping speeds,lubrication conditions and blank holder forces.The experimental results showed that the IE value was firstly increased and then decreased with the increasing of blank holder force.As the stamping speed increasing,the IE value gradually increasesd.The lubrication conditions also had a certain effect on the bulging performance of the sheet metal.The better the lubrication condition was the IE value gradually increased.
