FIELD: blasting operations.
SUBSTANCE: in the device for forming comprising a steel housing, a bottom with a support on the stand and an armoured casing, the inner part of the steel housing repeats the outer shape of the armoured casing made in the form of a tube of the stepped configuration and a spherical bottom. For the radial fixation of the device in operation with long length charges the housing is additionally provided along the outer surface with three circumferential reinforcement ribs and the upper flange. For axial fixation of the device the lower and the upper reinforcement ribs are made with the circumferential flanges. The stand has a massive base which diameter is 2-2.2 times greater than the diameter of the housing.
EFFECT: forming the long length charges of the stepped configuration with a spherical bottom, rigidity and stability of the press mould in all process operations.
