Abstract

PURPOSE:To bring the outside peripheral edge of a bulge part of a circular stock to spinning forming in a flat shape by forming a peripheral groove in the outside peripheral edge of a bulge part forming part of a mandrel. CONSTITUTION:A disk-like stock 2 is installed in a mandrel 1, the stock 2 is rotated centering around the axis center O together with the mandrel 1, and when the surface of the stock 2 is ironed along the forming surface 11 of the mandrel 1 by a pressure roller 3, a bulge part 21 is formed in the stock 2. In this case, since a peripheral groove 12 is formed in the outside peripheral edge part of a bulge part forming part 111, a rotary roller 3 is apt to grow conformable to the outside peripheral edge part of the bulge part forming part 111, although its tip face has a curvature. Therefore, the outside peripheral edge part of the bulge part 21 of the stock 2 can be brought to spinning forming in a flat shape.
