The present disclosure discloses a device and a method for forming a metal plate by using a high-energy electric pulse to drive an energetic material. The device includes high-energy pulse discharge equipment, an intelligent robot arm control system, a vacuum pumping device, a hydraulic press, a forming die, positive and negative electrodes, an energetic rod, and liquid supply equipment. According to the present disclosure, energy of a metal wire is added to energy of an energetic material after energy release to implement high-rate forming of the plate. A discharge voltage of the high-energy pulse discharge equipment is reduced and a service life thereof is prolonged. The discharge equipment is triggered by the manufactured small-size electric pulse metal wire, thereby reducing a volume and costs of the equipment and miniaturizing the equipment to implement precise operating, forming, and intelligent integration with the robot arm control system.

A method for electrohydraulic forming a material blank includes: a material blank to be shaped is placed between a mould and a blank holder; a tight cavity containing electrodes is filled with liquid up to a predetermined liquid level; the material blank is brought into contact with the liquid of the cavity; the material blank is hydraulically preformed; and the material blank is electrohydraulically formed. The liquid of the cavity is pressurised for the hydraulic preforming by moving all or part of one of the walls of the cavity.

An electrohydraulic forming device includes a mold, a tank having a first wall, and a first electrode and second electrode both placed in the tank and adapted to generate an electrical discharge to create at least one pressure wave. The first wall is rotationally symmetric about an axis of revolution, the electrodes have axes of revolution that are coincident with the axis of revolution of the first wall, and the first wall has a concavity oriented towards the mold.
