Abstract

742,460. Stamping. UNION CARBIDE & CARBON CORPORATION. June 11, 1952, No. 17036/54. Divided out of 742,387, [Group II]. Class 83 (4). A method of forming sheet metal is characterized by superimposing the sheet metal over a die and directing against the exposed surface of the sheet metal detonation waves produced by igniting a detonatable mixture of a fluid fuel and an oxidizing gas within an elongated container having an open end. A combustible gas, e.g. acetylene, hydrogen, propane, butane, pentane or ethylene is supplied through a pipe 10 and an oxidizing gas, e.g. air is supplied through a pipe 11 to a mixing chamber 12 from where the gaseous charge passes into an ignition chamber 14 provided with a spark plug 15 which is fired by a coil 17, a battery 18 and a cam-operated switch 19 regulated by a variable-speed motor 20. Firing of the plug ignites the charge and a detonation wave travels through a water or air cooled barrel 16 and out its open end. A back-fire arrester may be inserted in the fuel supply line. Liquid fuels such as gasoline may be vaporized and used and also solid fuels such as coal powder suspended as dusts in a gas. The sheet metal may be cooled by air blast, liquid spray or fog. An electrically heated filament or injected hot powder particles may be used instead of the spark plug.
