The invention provides a device for constant-pressure electromagnetic forming of a metal plate under the action of heterodromous currents. The device comprises a u-shaped mold, and further comprises acapacitance power module, a magnet supply branch and two vertical side pressing plates. The capacitance power module comprises an energy storage capacitor. The magnet supply branch comprises a constant-pressure coil and is connected to the two ends of the capacitance power module. The upper ends of the side pressing plates are bent oppositely and extend to form closed plates, and therefore a containing cavity with an opening being downward is formed between the two side pressing plates and below the two closed plates. The constant-pressure coil is fixedly arranged in the containing cavity. During use, a power supply branch is formed by the two closed plates, the two side pressing plates and the to-be-formed metal plate; the power supply branch and the magnet supply branch are connected inparallel and are connected to the two ends of the capacitance power module by taking the free ends of the two closed plates as the electric access points.
