摘　　要：阐述弹簧成型的原理,弹簧机成型技术方案,提出一种难变形的金属坯料电场辅助成型装置,利用电流流经高强度、塑性低的坯料所产生的焦耳电阻热直接对金属坯料本身进行加热,从而塑性变形。This paper expounds the principle of spring forming and the technical scheme of spring machine forming, and puts forward a kind of electric field auxiliary forming device for metal billets that is difficult to deform. The joule resistance heat generated by the current flowing through the billets with high strength and low plasticity directly heats the metal billets themselves, thus plastic deformation.

关 键 词：电场辅助成型 焦耳电阻 弹簧成型
