Abstract
PURPOSE:To improve the work efficiency by forming a bent part of a cleavage piece linked with a bent piece, in a curved surface shape, and thereafter, executing the spinning forming, and forming the cleavage end in a curved surface at the time of ironing by a pressure tool. CONSTITUTION:A disk-like stock 1 is inserted and held by mandrels 2, 2 and rotated centering around the axis center O. Subsequently, by a cleavage tool 31, a bent part of the stock 1 is cloven in the axis center direction, a cleavage groove 14 is formed, and also, a rim stock (cleavage piece) 15 linked with a bent piece 11, an a rim stock (cleavage piece) 16 which is not linked with the bent piece 11 are formed. A cleavage tool 31 used in this case is rotatable against a supporting shaft 32, has a cleavage edge 311 in the tip, and also, a curved part 312 is formed in a root part of the bent piece 11 side. Therefore, at the time of a cleavage work, when the curved part 312 of the cleavage tool 31 is allowed to abut on the cleavage end of the rim stock 15, this cleavage end can be formed in a curved surface shape.
