Abstract
PURPOSE:To prevent the generation of a crack in a bottom part of a V-groove and the generation of contraction at the outside of the bottom part of the V- groove by forming the pressure surface of a pressure tool to a curved surface in the axial direction of a disk-like stock, and also, inclining one side face in a tapered shape against the pressure surface direction. CONSTITUTION:A disk-like stock 1 is inserted and held by mandrels 3, 3, rotated centering around its axis center, and a V-groove 14 is smoothed by a rotary pressure roller 31. Thereafter, rim stocks 15, 16 are ironed along each mandrel 3, 3, and a vehicle use wheel is completed. In this case, the pressure surface of the rotary pressure roller 31 forms a curved surface in the axial direction of the disk-like stock 1. A radius (r) of this curved surface is set to 0.3t-1t, in case when thickness of the stock 1 is (t). Also, one side face of this pressure roller 31 is inclined in a tapered shape against the pressure surface direction, and an edge angle alpha of one side in the inclined surface is set to 15-35 deg.. In such a way, the generation of a crack in a bottom part of the V-groove, and the generation of contraction at the outside of the bottom part are prevented.
