Abstract

PURPOSE: To shorten the working time and to inexpensively manufacture the roller with spherical outer surface, at finishing the rough material for the roller with a specially constructed spherical outer surface, by performing the finishing work through the thread rolling by a couple of roller dies.
CONSTITUTION: The outer surface 2 of the rough material 1 for the roller has the breadth 1/4W 1/6 of the longitudinal length of the rough material 1, and is constructed with the parallel outer surface 3 with the approximately same outer diameter as the product size and the tapered outer surface 4 inclining at an angle 10W20 degrees against the axis of the rough material 1. Above rough material 1 is fittingly attached to the spindle 18 freely rotatably supported in the thread rolling apparatus 5, and is arranged between a couple of roller dies 6A, 6B. Roller dies 6A, 6B, are provided with a concave part 13 approximately the same as the spherical outward form of the product, and are freely rotatably supported by holders 8A, 8B; the distance between roller dies 6A, 6B, can be varied within the same surface of rotation by the driving shaft 9. By pushing the holder 8A toward the holder 8B, the spherical surface finishing for the rough material 1 is performed. Hereby, the roller with the spherical outer surface is inexpensively manufactued without processes of roughing and intermediate finishing.
