China International Youth Conference on Electrical Engineering (CIYCEE 2020)

Electromagnetic forming is a high-speed forming technology that uses Lorentz forces to achieve plastic forming of metallic workpieces, showing great potential in the manufacture of lightweight tubes and sheet metals. However, its industrial application is still quite limited due to bottlenecks such as the mechanical stability and thermal stability of tool coils during high-energy or high-cycle discharges, and the poor controllability of Lorentz forces in the existing forming process. To solve these issues, our team has previously developed a new electromagnetic forming technology at Wuhan National High Magnetic Field Center, that is, space-time-controlled multi-stage pulsed magnetic field forming and manufacturing technology. In the past five years, we have focused on the development of multi-coil electromagnetic systems and forming process of light alloy components related to this forming technology, which will be summarized in this talk based on the recently reported work.
