ELECTRICAL EXPLOSIVE CARTRIDGE FOR TUBULAR BLANKS PROCESSING Russian patent published in 1996 - IPC

FIELD: production of electrical explosive cartridges for tubular blanks processing. SUBSTANCE: 1. Electrical explosive cartridge for tubular blanks processing has cylindrical body of dielectric material and located in it filler and spiral explosive member. The electrical explosive cartridge for tubular blanks processing differs from others by the fact, that to increase its effectiveness and to expand its processing capabilities during usage for pipes reduction it is provided with reflector in the form of rigid cylindrical body mounted with contact with body wall. Body wall is made hollow and filler and explosive wire are located in its cavity on its inner surface. 2. Electrical explosive cartridge is corresponding to point 1 and differs from others by the fact, that to realize flaring of pipes reflector is made as rod mounted inside body 3. Electrical explosive cartridge is corresponding to point 1 and differs from others by the fact, that to realize reduction reflector is made in the form of cylindrical magazine mounted outside body and having strength, that exceeds strength of reduced pipe. EFFECT: increased effectiveness and expanded processing capabilities.
