Finite Element Method on Electromagnetic Shaping for Aluminum Alloy Sheet Parts

摘要

In this paper, the distribution of magnetic forces of uniform pressure coil and the electromagnetic shaping with die of aluminum alloy 1060 surface parts will be researched using the finite element method. The results show that: Uniform pressure coil can produce a uniform magnetic pressure on the sheet; The springback after electromagnetic aimed stamping is smaller than the springback after normal stamping; Before achieving the best results, with the discharge energy increases, springback will be smaller; with greater punch and die clearance, greater energy will be needed to achieve the best effect; Too large discharge energy will lead sheet bounce after punch, springback increases.
