Reduction of corner radius of cylindrical parts by magnetic force under various loading methods

Journal Article


Abstract


  • To prevent small corner radius of cylindrical parts from cracking near the sheet bottom corner during deep drawing, a new method combining multidirection magnetic force electromagnetic forming and traditional stamping is proposed in this paper. First, a punch with an 8-mm corner radius is used to obtain a cylindrical part. Then, a coil-generated multidirection magnetic force is used to further deform the sheet corner radius and obtain a smaller corner radius. ANSYS/emag and ABAQUS/explicit software are used to calculate the multiphysical field coupling process in electromagnetic forming (EMF), and obtain accurate simulation data based on the experimental results. We found the following that the maximum thickness thinning ratio was 20% in the sheet corner region with an applied multidirection magnetic force in comparison to 33% if only a bulging coil was used.
