Inverse bending and springback-control using magnetic pulse forming

Journal Article


Abstract


  • In this study, electromagnetic-assisted stamping (EMAS) with magnetic-force reverse loading was introduced to control springback. Compared to conventional EMAS, this new method does not change the mold structure used in traditional stamping technology. Thus, this approach can greatly extend the operating lifetime of the mold and readily be adopted for commercial production. Results indicate that the equivalent plastic strain and the plastic dissipation energy increase, while the tangential stress and the elastic strain energy decrease considerably, with increasing in discharge-voltage. The simulation results accurately predict the sheet deformation for quasi-static stamping and dynamic magnetic pulse forming. Both simulations and experiments show that the angle after springback decreases with increasing in discharge-voltage.
