Title: Manufacture of gear having chamfer
Inventor: KOIDE YOJI
IPC: B21K1/30
Filed: 1993-03-29
Abstract: PURPOSE:To prevent lack of fill at the tip part of a chamfer by intensely pressing the axial end surface of a projecting tooth with a V-shaped wall surface of a chamfer forming die while facing the restricting wall surface of the chamfer forming to the tooth surface of the projecting tooth to execute a cold-forging for formation to the chamfer. CONSTITUTION:The V-shaped groove 40 in an upper punch 39 is formed with the V-shaped wall surface 41 having V-shaped bottom 41. While facing the restricting wall surface 44 of the punching die 39 to the tooth surface 10m in an inner tooth 10, the V-shaped wall surface 41 of the upper punching die 39 is intensely pressed to the axial end surface 10x at the upper side of the inner tooth 10, and by this method, the chamfer 17 having the inclining wall surface matching to the V-shaped wall surface 41 of the upper punching die 39 is formed. Therefore, by restraining the excess thickness on the tooth surface at the tooth surface 10m with the restricting wall surface 44, the surface pressure at the tip part 17e of the chamfer is risen and the formation of the sharp tip part can easily be obtd.
