Abstract

The present disclosure provides a method for forging a gear capable of preventing burrs from being formed at an edge of the surface opposite to a direction in which a material in external teeth of the material is pushed. A first exemplary aspect is a method for moving the second punch along a tooth profile groove of the guide die to stack the material and the second punch in this order; and pushing the material and the second punch into a tooth profile groove of the tooth profile die in a stacked state to pass them therethrough, in which a tooth pressing part of the second punch covers at least an edge of a region where external teeth are formed on a surface of the material on the first punch side.
