Abstract
PURPOSE:To easily manufacture a gear in good yield and with high accuracy by upsetting a round bar material and forming a hole part in a warm temperature range, then, making warm extrusion of the tooth part, further, making cold sizing of the tooth part. CONSTITUTION:A work W in a disk shape obtained by heating and swaging round bar material in a warm temperature range is mounted on a die 36 of a die assembly 32. Then, an upper die 44 is lowered and a punch 48 fitted to it and a punch 50 for forming a hole part which is fitted slidably in the punch 48 form a hole part 100 and a projection 102. Then, the work W is arranged in the recess part 58 of a pierce die 56 of a pierce die assembly 52. Then a pierce punch 64 is lowered to provide a through hole 104. This work W is moved to an extruding die assembly 70 and a gear and the prescribed shape of the gear are formed by a punch 74 with a plurality of protrusions 78, a gear-forming member 80 with a bulge part 84 engaged with said protrusions 78 and a die 88. Then, a cold sizing is given to the tooth part. In this manner, a gear can be obtained without intermediate treatment such as normalizing.
