Abstract
PURPOSE: To manufacture the threadless coupling, by cutting the rectangular blank material along the V-groove formed in depth half of the thickness, by sizing the cutting plane so as to possess a uniform tilt angle, and then, by bending this blank material into a tubular shape by solidly fitting the tongue into the groove both being formed in opposite sides of the blank material.
CONSTITUTION: After tapping the setscrew hole 1 in the hoop A, the V-groove 3 in depth (h) is formed in the hoop A by the V-punch 2 possessing the curling part 2a at the tip and the tilt angle 2θ. Next, the hoop A is cut by the die 4 and the punch 5 and a rectangular blank material 9 is obtained; the cutting plane of the blank material 9 is sized so as to possess a uniform tilt angle θ, and the tongue 7 in one side plane and the groove 8 in another side plane are formed. This tongue 7 is fitted to the groove 8 without causing the galling and the threadless coupling 15 in tubular shape is obtained. The pipes 16, 16 are inserted into this coupling 15, and the setscrew 17 is screwed into the setscrew hole 1; hereby, the jointing work for the pipes 16, 16 is finished.
