    摘要: An apparatus for forming a generally planar metal plate into a dish with a three-dimensional pattern is provided. The apparatus comprises a mold having a forming surface with a contour corresponding to said three-dimensional pattern, and having edges corresponding to boundaries of the dish, which edges are defined by side walls essentially perpendicular to the forming plane; a forming device comprising a fluid basin and pairs of electric discharge members within the fluid and having an opening facing the mold to allow transmission of a pressure wave from the fluid to the metal plate; and an electric discharge circuitry for discharging a short and intense electric current through the pairs of electric discharge members generating an electric spark or breakdown within the fluid to yield formation of plasma, vapor or both.

    摘要: A method for generating an underliquid shock pressure comprises the steps of igniting a combustible mixture gas to form detonation waves, imploding the detonation waves in their advancing direction, propagating a pressure obtained by imploding the detonation waves to a liquid, and converting the pressure to an underliquid pressure which is applied to a workpiece. The pressure obtained by imploding the detonation waves may be applied directly to an elastic rubber body (G), thus converting the pressure to an underelastomer shock pressure, which is then applied to the workpiece via the elastic body. An apparatus for generating an underliquid shock pressure comprises a combustion chamber (1) whose cross-sectional area decreases from one end toward the other end of the chamber, an ignition chamber (4) to which fuel is fed and in which a spark plug (5) is positioned, a plurality of guidance paths (2) extending from the ignition chamber (4) and communicating with one end of the combustion chamber (1), each of the guidance paths (2) having substantially the same length, and a pressure medium chamber (12) connected to an opening of the other end of the combusiton chamber (1) having the smallest cross-sectional area. The pressure at the smallest cross-sectional area end of the combustion chamber (1) is applied to a liquid to convert the pressure into underliquid shock pressure, which is then applied to a workpiece either directly or via an elastic body interposed between the liquid and the workpiece.
