ABSTRACT:
A device for electrohydraulic die-forging comprises an explosion chamber and a die with a blank pressed against said chamber in the course of die-forging. The mechanism for moving the die plate and pressing the die against the explosion chamber is formed by a kinematic screw-and-nut pair. The progressively moving element of said pair is rigidly connected to the die plate, whereas the rotatable element of said pair is kinematically linked with a drive for moving said die plate. The rotatable element is also linked kinematically with an independent drive for pressing the die against the explosion chamber when the die plate drive is disconnected.
