ABSTRACT:
This invention relates to tube bending mandrels and, more particularly, to an improved version thereof characterized by a threaded connection between the tube-shaping ring and the necks of the ball-carrying links that functions in cooperation with an annular stop-forming rib and a retaining ring at opposite ends of the threaded link neck section to resist equally well both tension loads and compression loads while maintaining precise axial spacing between subassemblies in an assembly where, except for the links at opposite extremities, all parts remain fully interchangeable.
