Abstract
PURPOSE: To facilitate the bending and forming of the coupling, and to keep the good roundness of it, by parallelly making V-groove in the inside of the plate perpendicular to the direction of the bending.
CONSTITUTION: A band-shaped plate 2 having anticorrosion coating is continuously run, being chamfered of its side face by a roll 3. Then V-grooves 22 are parallel formed in the bottom face of the hoop at right angles to the feeding direction by a V-notch coining roll 23. The holes 4, 4 before threading are made by a punch 21 plus a die and the holes 4, 4 before threading are deburred 5, and the deburred cylindrical inner face 5a is threaded by rolling. Then it is so cut off that it contains dove tailed part 6, 6 at its root and tip. Next, it is bent around the cylindrical core, and a material 8 is finally formed to a pipe. This method facilitates the bending and enables continuous forming of plate and achieving of high productivity.
