Abstract

PURPOSE: To press a hand body part and a pipe part into one body, and improve the productivity of the watch hand of a small size and a thin shape by breaking through a flat plate blank material with a broach of a circular cone shape, thereby forming the pipe part.
CONSTITUTION: When a blank material 10 of a flat plate shape is progressively fed and is positioned, a stripper 26 descends to press the plate 10 to a lower bushing 20 and an intermediate ring 22. Simultaneously with the descending of the stripper 26 or with slight delay therefrom, a broach 24 descends to break through the plate 10. At this time, the plate is broken through by the leading end 24a of a circular cone shape of the broach 24, and a pipe part 11 is formed on the rear surface of the plate 10 by the slant surface of the end 24a. Since the rear surface of the plate 10 is formed of the pipe part 11 while held supported by a receiving bar 23, a top surface 12 assumes the same state as finish pressing. Next, the pipe part 11 is inserted into a recessed part 30a, and is located. Thence, a broach 32 and a stripper 34 descend to size the bore, then to blank the outside shape, after which the surface 14 of a hand body part 13 is diagonally cut to a prescribed size (t) in thickness.
