Abstract:
A tool kit for swaging tube ends, comprising:a clamping bar set having a width, a length and means for clamping a tube end to be swaged;a swaging die having a spaced-apart parallel drive end and swaging ends, a cylindrical shape between said drive end and said swaging end and a tube-forming cavity in a center of said swaging end;a saddle collar having an annular shape, an inside diameter and an outside diameter, said inside diameter being a first fit dimension over said cylindrical shape of said swaging die for providing for a fitted engagement thereof over said swaging die, and said outside diameter being larger than said width of said clamping bar set; said saddle collar further having a pair of tabs spaced apart a second fit dimension over said width of said clamping bar set for providing for a fitted engagement thereof over said clamping bar set with said tabs extending astride said clamping bar set;a flaring yoke having a pair of legs spaced apart a third fit dimension over said outside diameter of said saddle collar for providing for a precise installation thereof over said saddle collar with said legs extending astride said outside diameter of said saddle collar; said flaring yoke also having hook means on said legs for engagement with said clamping bar set, and a screw press centered between said legs and having means for engagement with said swaging die for pressing said swaging die on a tube end to be formed;such that said swaging die is concentrically mountable on a tube end when said tube end is adapted to be clamped in said clamping bar set; said saddle collar is concentrically mountable over said swaging die and said flaring yoke is precisely installable on said clamping bar set with said legs extending astride said clamping bar set and said saddle collar, and is positional with said legs being in simultaneous contact with said clamping bar set and with said saddle collar in a pair of notches defined by an integration of said clamping bar set and said saddle collar and is restrainable longitudinally and transversally in said notches relative to said clamping bar set and said saddle collar, for maintaining said screw press centered with an axis of said tube end.
