Abstract：

The electromagnetic forming process of sheet metal in small area and the influence law of magnetic collector on the distribution of electromagnetic force for sheet metal were studied by using the plate electromagnetic forming system with magnetic collector. The results show that the sheet metal can complete the deformation of small area through the magnetic field aggregation of magnetic collector, the forming effect is good, and the sheet metal can cling to the punch. The deformation of sheet metal is mainly divided into three stages. First, the central area of sheet metal undergoes minor deformation due to electromagnetic force. Then, with the increasing of electromagnetic force and a certain forming speed obtained by the sheet metal, the central area rapidly completes deformation. Finally, the force-bearing area moves to the outer end of sheet metal, and under the joint action of inertia, the overall downward movement occurs to complete the deformation. The magnetic collector can concentrate the force-bearing area of sheet metal in an area with a central radius of about 15 mm, and the forming height of sheet metal is 4 mm.
