Abstract
PURPOSE: To fabricate threads with high productibility and no losses in material by form rolling threads on projecting parts of a sheet material having projecting parts at one end and, recesses at another end, and then applying a bending process.
CONSTITUTION: In the first process of a developed hooplike slab 1 this slab is subjected beveling work by a roll 2 having tapered faces 2a, 2a on both edges of the hoop sheet, and in the second process, crest parts 3 and torough parts 4 are formed with three parts each respectively by a punch and a die. In the third process, thread parts 5 to form split threads are rolled out by a thread rolling roll, and in the fourth process, a hooplike slab including projecting parts 6, 6 is cut off. Thus a sheet material 8 having a wave form is formed by the fourth process. Then a cylindrical column 9 having escape grooves 9a... at the places corresponding to the three crest parts 3, is used as a core body and the sheet material 8 is bent to a cylindrical tube on it by mauls 10, securing the formed shape with the projecting parts 6 on one end fitted to the recesses 7 on another end, thus a coupling with threads A being completed of its fabrication.
