The utility model relates to the field of metal forming and can be used for stamping parts from sheet material, mainly in small-scale and pilot production. The device for sheet gas stamping contains a coaxially mounted matrix with an internal cavity and a combustion chamber equipped with means for supplying and igniting the gas mixture and exhausting the combustion products, and an annular cavity enclosing the internal cavity of the matrix, in which an annular piston interacting with the die blank is placed. The device comprises a working cylinder with a piston connected through a check valve to the receiver. The combustion chamber is communicated by a bypass valve with a working cylinder. The receiver is connected via control valves to the combustion chamber and the matrix cavity. The result is a reduction in energy consumption. 1 ill.
