Abstract
PURPOSE:To prevent the eccentricity of a blank and to obtain the forming part of the quality stabilized with high accuracy by pushing an intermediate forming blank into a die with the state of interposing the guide means regulating the displacing direction of the intermediate forming blank. CONSTITUTION:The center hole of the stock 12 having the rough tooth profile 12a subjected to rough working is fitted to the upper end part 9a of a guide ring 9 and also the phasing of the rough tooth profile 12a of the stock 12 for the finishing tooth profile 7 of a die 4 is performed. Then when a push punch 2 is descended with a movable board 1, the lower face 2a of the punch 2 and the upper face 12b of the stock 12 are abutted. At this time, the stock 12 is supported by floating elastically in the axial direction via the guide ring 9, so the punch lower face 2a and the stock upper end face 12c are closely fitted correctly by the reaction force of a cushioning member 14 and the squareness of the stock upper end face 12c for the axial line of the die 4 is corrected. With further descent of the punch 2, the stock 12 is pushed in to the die 4 as of the state of being interposed by the punch 2 and guide ring 9. The axial line of the stock 12 is thus maintained correctly.
