Abstract：

Magnetic pulse piercing is a kind of high energy rate forming technology and can be applied in thin plank forming specially.Under three different forming modes,the effect of discharge voltage on piercing property is analyzed.The experimental results indicate that the minimum discharge voltage of piercing ascents with the increasing of blank thickness and cross section quality is better when the discharge voltage is higher than the minimum discharge voltage under the same blank thickness.At the same time,among the three modes,when the blank is placed between elastic mediums,the burr area is of minimum and the cross section quality is the best,but the energy is of maximum.
