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.

摘要： PURPOSE:To produce the strength parts made of high tensile steel plates for automobiles by generating the pressure of detonation by ignition of a combustible gaseous mixture as a liquid pressure or elastic pressure and pressing primary molded goods via a film member or directly to second molds. CONSTITUTION:A pressure chamber 32 is connected to the bottom end 21B of a combustion chamber 21 and rubber 4 is housed as a pressure medium in a pressure chamber 32 and is provided right thereunder with a molding device 33. The upper part of this rubber 4 directly faces the bottom end 21B of the combustion chamber 21. A pipe 34 for air venting and a liquid supplying pipe 35 for water, etc., for liquid pressure are connected via valves to the pressure chamber 32. The high-liquid pressure or elastic pressure is generated and impulsive waves are propagated in the circular conical part of the rubber 4 from above to below, by which the high impact pressure is applied on the inner side of the primary molded goods 5. The side wall parts of the primary molded goods 5 receive tensile force and high surface pressure at this time and, therefore, the shape thereof is corrected. As a result, the strength parts for automobiles having good dimensional accuracy are obtd.

摘要： PURPOSE:To shorten the time required for working, to decrease required energy and to simplify the device by pressing a member to be worked to a metal mold via a film body or directly by a liquid pressure or elastical pressure and simultaneously subjecting the member to molding and blanking. CONSTITUTION:The metal mold 16 supporting the member P which is to be worked and is subjected to the pressure via the film body or directly is housed in a working chamber 13. A recessed part 16A having a blade-shaped edge for blanking is formed on the surface of the metal mold. Then, the pressure obtd. by detonation is converged to a high-pressure impact pressure which is then propagated to a pressure chamber 12. This pressure arrives at the member P to be worked through the pressure medium. The member P to be worked is thrust away by receiving this high-pressure impact pressure and is molded along the metal mold surface; in succession, the member is subjected to blanking by the blade-shaped edge part 16A of the recessed part. Since explosives are not used, the device which is not restricted in setting is obtd. Handling of the work, etc., is facilitated in the system of transmitting pressure waves via the film body.

摘要： PURPOSE:To promote the dissolution of gas in a solution by converting gas pressure due to detonation to liquid pressure or pressure caused by an elastic body. CONSTITUTION:A combustion chamber 1 is set so that the cross section thereof gradually becomes small from one end part 1A thereof with the advance of a flame and a convergent part having the min. passage cross section is formed to the other end part 1B of the combustion chamber 1 and the upper surface of a pressure chamber 12 faces to the opening part of the other end part 1B. Since the cross section of the combustion chamber 1 becomes small with the advance of a flame, the pressure in the combustion chamber is raised in the advance direction of the flame and becomes extremely high at the other end part 1B. This high pressure is transmitted to the pressure medium in the pressure chamber 12 and the dissolution of gas in the solution of a solution treatment apparatus 13 is promoted by pressure.

摘要： PURPOSE:To provide the method for converting the gaseous pressure by detonation to an elastic pressure and the device for the method. CONSTITUTION:A combustion chamber 1 is so set that its sectional area decreases gradually from one end 1A on progression of a flame. A convergent part hating the min. passage sectional area is formed at the other end 1B. An elastic pressure chamber 12 housing an elastic body faces the aperture of the other end 1B. The sectional area of the combustion chamber 1 decreases on progression of the flame in the combustion chamber and, therefore, the pressure increases and the extremely high pressure is generated at the other end 1B. This high pressure is transmitted via the fluid 25 in the elastic pressure chamber 12 to the elastic body. A molding chamber 13 is provided to communicate with the elastic pressure chamber 12 and a mold 16 for molding supporting a member P to be molded is housed in the molding chamber 13. The shape and size of the elastic pressure chamber 12 or the properties of the elastic body are properly changeable. The elastic body in the elastic pressure chamber 12 is deformed by applying a pressure to the fluid 25, by which the structure of the elastic body coming into tight contact with the member P to be formed is obtd.

摘要： PURPOSE:To easily and inexpensively work a surface treated material with good accuracy by subjecting the peripheral edge of a surface treated material to molding while applying blank holding force of an equal pressure via a soft elastic material thereon. CONSTITUTION:The blank holding force of the equal pressure is applied by a blank holding cylinder 20 and a reinforcing block via the soft elastic material 19 on the peripheral edge of a plate material P. A film material 18 consisting of a ductile material or a lubricating oil is disposed between the plate material P and a die 16 when the surface treated surface of the plate material P comes into contact with the die 16. Molding is then executed by utilizing detonation. The peripheral edge of the plate material P is worked in the state of restraining the peripheral edge by a high pressure and in the state that a high water pressure or elastic pressure acts instantaneously on the plate material P and, therefore, the surface treated surface is not damaged even if the surface treated surface directly receives such water pressure or elastic pressure. The film material 18 is also disposed to prevent the direct contact of the surface treated surface with the die even if the surface treated surface comes into contact with the die 16 and, therefore, the surface treated surface is not damaged.
