Abstract (en)
A clutch gear manufacturing apparatus includes a die (16) that allows a clutch gear primary product (Wb), which has spline teeth (1) with chamfers (1a) formed in an outer peripheral surface of the primary product (Wb), to be disposed in the die (16), and includes a blade(16a) capable of forming reverse tapers (1b) at the spline teeth (1); a punch (18) capable of pressing down the primary product (Wb) disposed in the die (16) so that the spline teeth (1) are pressed by the blade (16a); a knockout sleeve (17) that receives the primary product (Wb) which is pressed down by the punch (18); and a punch pin (31) that forms a cone hole (4) in a side surface of the primary product (Wb) while the spline teeth (1) are pressed by the blade (16a).
