Device for electrohydraulic die-forging

A device, for electrohydraulic die-forging of a blank, having a bed and at least two parallel columns secured on said bed;

• said device comprising a first plate rigidly secured on said columns;
• an explosion chamber located on said plate and adapted to contain a fluid;
• a power source;
• an electrode arranged in said explosion chamber and connected electrically to said power source;
• a wall of said explosion chamber serving as a second grounded electrode;
• a die supporting said blank mounted on another or second plate set parallel to said first plate and adapted to move towards and away from said first plate along said columns for moving said die and blank and pressing same against said explosion chamber in the course of die-forging;
• a mechanism for moving said second plate and pressing it against said explosion chamber being in the form of a kinematic screw-and-nut pair;
• said mechanism comprising a progressively moving element rigidly connected with said second plate;
• a rotatable element mounted on said bed;
• a drive system for progressively moving said second plate;
• and independent drive of said mechanism for pressing said die and blank against said explosion chamber;
• and said rotatable element being linked kinematically with said drive system of said second plate and with said independent drive for pressing said die and blank against said explosion chamber, whereby said die and blank are brought into contact with the explosion chamber and pressed thereagainst by the action of said drive system and said independent drive.
