Abstract
An electro-hydraulic forming machine () for the plastic deformation of a projectile part (P) of the wall (P) of a workpiece (P) to be formed, preferably a cylindrical tubular workpiece, via a forming fluid (F), includes a tool () for applying the forming fluid on the inner face (P) of the projectile part (P), the application tool () including:—a chamber () intended to contain the forming fluid (F), cooperating with elements () for generating a shock wave in the forming fluid (F) intended to be contained in the chamber (), and—at least one downstream port (), intended to open opposite the projectile part (P) of the wall (P) to be deformed and in fluid communication with the chamber (), in order to allow the passage of the forming fluid and for propagating the generated shock wave towards the footprint () of a target support ().
