Abstract
An improved electro-hydraulic clinching system involves generating, through a high potential electric shock, a forceful wave in a fluid such as water, and applying the force of the wave to a sheet of metal. The force of the wave results in deforming the sheet and making the sheet material move through a hole in a second sheet adjacent to the first sheet, thus joining the two sheets. In an alternative implementation, in which neither sheet includes an opening, the force of the wave moves both sheets simultaneously, thereby causing them to join together at the point of impact.
Claims20
An electro-hydraulic clinching system for joining a first sheet to a second sheet comprising:
- a movable casing having a positioning rod for aligning a hole in the first sheet with a die cavity of the movable casing;
- a pressure chamber including a cavity for housing a fluid;
- two opposing electrodes, one located on one side of the pressure chamber cavity and the other located on the other side of the pressure chamber cavity;
- a channel for inputting the fluid in the cavity for housing the fluid,
- wherein a discharge of electric current between the two opposing electrodes creates a shock wave in the fluid that causes the fluid to move with force against the second sheet, and the force causes deformation in the second sheet by moving materials of the second sheet into the hole of the first sheet thereby joining the first and second sheets.

- a channel for inputting the fluid in the cavity for housing the fluid;
- and
- a movable piston positioned on top of the cavity for housing the fluid,
- wherein an electric discharge between the two opposing electrodes creates a shock wave in the fluid that causes the fluid to move against the piston causing the piston to move and thereby create a force against the second sheet and the first sheet positioned on top of the second sheet, and the force causes deformation in the first sheet and the second sheet by moving materials of the first sheet and the second sheet into a die cavity of the casing thereby joining the first sheet to the second sheet.
