摘要： A coupling for swaged attachment to thin wall tubing. The coupling is a cylindrical body with a longitudinal axis and an inner peripheral wall. At least one groove is located in the inner peripheral wall. In one embodiment, the groove is substantially rectangular in cross section. The rectangular groove has a base and two side walls. The side walls meet the base to form corners. The corners have a radius of curvature of at least the depth of the groove. Alternatively, the cross section of the groove can be ramped in shape. The ramped shape groove has a base and two side walls. One of the two side walls meets the base at about 90.degree., and the second side wall meets the base at an angle substantially greater than 90.degree.. In a third embodiment of the invention, the groove is ramped with one side wall meeting the inner peripheral wall of the coupling sleeve at about 90.degree., and a second side wall meeting the inner peripheral sleeve of the inner peripheral wall of the coupling sleeve at substantially less than 90.degree.. The preferred material for the coupling sleeve for aerospace use is titanium.

摘要： A machine and method for roller swaging hydraulic fitting sleeves onto metallic tubing comprises a tapered roller mandrel expander driven at a first high speed for rapidly expanding the tubing and at a second low speed until the drive torque reaches a final preselected value for preventing springback of the tubing and accurately controlling the amount of swaging. Both torque control of swaging and diameter control of swaging can be effected. A torque transducer monitors mandrel loading for automatic control of machine operations. A mechanical stop for interaction with the mandrel support regulates advance of the mandrel and thereby relates to diameter control. The diameter control is effected by torque measurements which are responsive to diameter positions. Low speed burnishing can be effected during diameter control at the end of the cycle. The machine provides an automatic swaging cycle with an optimum overall time cycle for swaging performance.

摘要： A machine, which is portable, and method for roller swaging hydraulic fitting sleeves onto metallic tubing comprises a tapered roller mandrel expander under either or both torque control of swaging or diameter control of swaging. The machine provides an automatic swaging cycle with an optimum overall time cycle for swaging performance. A motor drive is movably mounted relative to the mandrel expander assembly. The motor drive is manually moved longitudinally to activate the mandrel. Portability and hand held use can be effected by removing the power unit from the frame.
