把冲击的电磁力用到金属成形加工上,这种方法称电磁成形法。电磁成形与爆炸成形及液体中放电成形一样,属于高能速度加工。也就是利用电气、化学或机械贮存的高能量在瞬间放出而进行加工。电磁成形和爆炸成形都能达到15～300米/秒的加工速度,每小时成形量达10000个以上。电磁成形适用于管、板及粉末的高速成形加工。国外在1959年开始研究,现已进入实用阶段,是很有前途的一种加工方法.
The impact of electromagnetic force used in metal forming, this method is called electromagnetic forming method. Electromagnetic forming and explosion and liquid discharge forming the same, are high-speed processing. That is, the use of electrical, chemical or mechanical storage of high energy in an instant release and processing. Electromagnetic forming and explosion forming can reach 15 ~ 300 m / s processing speed, forming more than 10,000 per hour. Electromagnetic forming is suitable for high-speed forming of tubes, plates and powders. Foreign countries began to study in 1959, has now entered a practical stage, is a promising method of processing.
