Abstract:
1. An electrode assembly for an electro-hydraulic forming tool that defines a chamber that is filled with a liquid, comprising an electrode rod having a chamber end and a connector end; and an insulation sleeve assembled over the electrode rod, the insulation sleeve having an inner end adjacent the chamber end of the electrode rod and an outer end adjacent to the connector end of the electrode rod, a deflection surface provided at the chamber end of the insulation sleeve that forms a tapered surface between the chamber end of the electrode rod and the chamber and that is narrowest by the electrode to deflect the force of a discharge of the electro-hydraulic forming tool, wherein the deflection surface is formed on a metal cap that is assembled over the electrode rod and axially between the inner end of the insulation sleeve and the chamber end of the electrode rod.
