Numerical modeling of industrial parts manufacturing using electromagnetic hemming process
Abstract
In the contemporary times, electromagnetic forming process (EMF) is one of the most attractive high-velocity forming methods that can be used in order to achieve many industrial applications in sheet metal forming. Taking into account the advantages and limitations of EMF, this technology is highly used in the automotive industry and has increasing potential applications such as Flanging, Bending, and Hemming processes. Hemming is the process that bends the edges of sheets and serves to increase their stiffness and improve their appearance. In this paper, we aim to investigate the simulation of forming Aluminum sheets using electromagnetic hemming process in order to enhance our understanding of the process and its efficiency, particularly in industrial applications used for automotive panel production. Specifically, an electromagnetic bulging device serves as the fundamental setup for our various applications. This study undertakes multiple numerical simulations using the finite element method to explore the impact of process parameters on the deformed sheet. Additionally, we investigate the temperature distribution across the sheet during hemming. The numerical results demonstrate strong agreement with experimental data and existing research.
