Explosively propelled equal mass tubular member swaging tool

摘要

An improved tool is disclosed for joining the adjacent ends of pipes, conduits, and like tubular members through the use of explosively propelled swaging members. The tool includes a jacket assembly defining a closed chamber having a die at one end thereof and a die assembly which is received in the chamber. Both the die assembly and jacket assembly are substantially cylindrical to encompass end portions of the tubular members to be joined. The masses of the die assembly and of the jacket assembly are substantially equal so that, when the explosive propellant is ignited, they travel at substantially equal speeds in opposite directions with the die faces travelling towards one another to effect a swaging of a sleeve connector on the respective ends of the tubular members or bell configuration of one member onto a straight end of the adjacent member.
