摘要：
Electromagnetic blank holder (EBH) is a novel technology of deep drawing for sheet metal. The electromagnetic control of variable blank holder force ( BHF) is studied in this paper. First, mathematical model of deep drawing process of cylindrical cup is established. The mathematical relationship between flange radius and deep drawing height in deep drawing process of cylindrical cup is analyzed. The reasonable range of BHF is calculated theoretically. Then, principle of EBH device is introduced, and its simulation model is built. The EBH control system is designed. The co-simulation method are used for verify the feasibility of system. Finally, simulation results of EBH control system are analyzed which include variable blank holder force, distribution of magnetic field, and electromagnetic force. The simulation results show that the distribution of magnetic field and electromagnetic force can meet the requirements of BHF distribution. The performance of the EBH control system is also good. The research results have a good role in promoting the development of electromagnetic blank holder control technology.
