Abstract

PURPOSE:To perform taper working with good workability and high efficiency, by inserting the stiffening metal fittings being in parallel with the pressure surface of a die, into a metallic pipe to be worked, in a floating state, and working the metallic pipe by pinch-sticking it by static inertia of the die and the stiffening metal fittings. CONSTITUTION:A device for executing this working is a swaging machine 8 provided with an outside circumference roller 6, a hammer 7, and plural dies 3 whose inside surface has been tapered, for instance, 4 dies 4, in order into a housing 5. Into this die 3, cylindrical stiffening metal fittings 9 are inserted at an angle theta, one end of its supporting lever 10 is installed to a supporting axis 11 so as to be rotatable, and a metallic pipe 2 is pinch-stuck and worked between the stiffening metal fittings 9 and the tapered inside wall of the die 3.
