Abstract

PURPOSE:To enable workings of rolling and ring-shape groove of a tooth form simultaneously, by providing the projecting strips, which extends in the direction of movement, on the face of at least one die of a pair of dies, in rolling device that forms a tooth form on a workpiece to be worked. CONSTITUTION:The teeth 12 of a flat die 10 are made gradually taller toward the direction opposite to the arrow y in part A, and made finishing teeth 11 in part B. Projecting strips 19, 20 having an apex angle of alpha and extending in the direction of movement of the die 10 are provided. A lower groove of ring-shape groove 22 is worked at an end of workpiece 21 to be worked, and the first slant 29 is made angle beta greater than angle alpha and the second slant 30 is made angle gamma smaller than angle alpha. The lower groove is aligned with the projecting strips 19, 20 and the die is moved. A shallow spline is rolled on the workpiece 21 in part A and pressed by the projecting strips 19, 20, and a part of material 32 becomes burr in the outside periphery. The spline becomes slightly deeper in part B and the burr disappears. By this way, a prescribed spline 31 and a ring shape groove 22 are worked simultaneously.
