Abstract (en)
[origin: WO2018028979A1] An indirect electrohydraulic press forming tool (110; 210) comprising: - a body (113; 213) comprising a tubular cylindrical zone (113a; 213a), - a chamber (115; 215) intended to be filled with a liquid, - two electrodes (116a, 116b; 216a, 216b), each of the electrodes having a portion arranged in the chamber (115; 215), - a punch (111; 211). The tool also comprises: - a piston (114; 214) mounted sliding in a sealed manner in the cylindrical zone and delimiting the chamber (115; 215) in a sealed manner. Moreover, the punch (111; 211) is carried by the piston (114; 214) on a face of the latter opposite the chamber (114b; 214a).
