Abstract

PURPOSE: To easily form the spline in the circumferential plane of the boss without loading large forming load on the die, by installing the circumferential groove at the position near the end part of the spline to be formed, around the circumferential plane of the boss projecting from the flange part, and by pressing the die in the direction of axis of this boss.
CONSTITUTION: The circumferential goove 6 is formed at the position near the end part of the spline 5 to be formed in the circumferential plane of the boss 3. The angle α of the side edge of the groove 6 on the side of the end face 3a of the boss 3 is suitable to be 0W60 degrees against the vertical direction. The spline forming die is pressed in the direction of axis of the boss 3 from the side of the end face 3a, for carrying out the cold forging work to form the spline 5 in the outer circumferential plane of the boss 3, ranging from the end face 3a to the groove 6. In this case, the wall of the outer circumferential plane of the boss 3, being thrusted toward the flange part 2 due to the formation of the spline 5, swells into the groove 6; as a result, the resistance against the load is reduced, so that the die becomes free from the large forming load.
