METHOD OF EXPLOSIVE GAS FORMING AND DEVICE FOR ITS EMBODIMENT Russian patent published in 1997 - IPC

FIELD: mechanical engineering, instrumentation engineering, construction industry; may be used in manufacture of metal bodies and shells of various applications. SUBSTANCE: simultaneously with building-up the pressure of combustible gas mixture onto one side of blank, counterpressure of the same value is exerted on the blank other side, and then it is relieved by pulses during the time of detonation of gas mixture and/or time of action of shock wave or explosion products on blank. These operations are accomplished with the help of device having die with one or more openings in bottom part, explosion chamber with gas piping and valves and member of detonation initiation valve for supply of gas or fluid under pressure to die, and unit of die pulse evacuation tightly joined with die bottom part. EFFECT: higher efficiency. 4 cl, 4 dwg
