Summary:In this paper, a novel electromagnetic blank holding system (EBHS) for a conventional drawing process is proposed. The system is created to substitute mechanical or hydraulic blank holder force (BHF) with mutually attractive electromagnetic force (EMF). The winding type of electromagnetic coils is determined as a single-coil through numerical simulation. For avoiding the fluctuation of the magnitude of BHF, direct current is chosen to generate BHF. Corresponding magnetic circuit model of the electromagnetic blank holding device (EBHD) has been established to find the mathematical relationship between EMF and input voltage. Besides, several groups of EMF testing data are measured to prove the correction of deduced expression. To validate the feasibility of the novel system, corresponding numerical simulation and experiment have been carried out. It is worth to mention that the cylindrical parts created by simulation and experiment at different BHF agree well with each other. Additionally, the thickness reduction rate of drawn part is controlled at a reasonable level with the application of EBHS, which well validates the effectiveness of the EBHS.
