Abstract

PURPOSE: To work a gear free from a underfill, exact in tooth profile and high in accuracy by forming an extruding introduction part where its tooth depth becomes gradually larger toward the extruding direction on the end part of the stock introduction side of a tooth profile forming part having a complete tooth depth.
CONSTITUTION: The internal tooth 11 of a die 2 is formed by a tooth profile forming part 11a having a length L1 and a complete tooth depth corresponding to the various dimensions of a gear to be worked and the extruding introduction part 11b having a length l1 smaller than L1 is formed continuously on the end part in the direction of a tooth trace of the tooth profile forming part 11a, in other words, on the end part of the stock introduction side. The extruding introduction part 11b is formed obliquely by a prescribed angle to an axial line in the extruding direction of the die 2 and established so that the tooth depth becomes gradually larger toward the extruding direction. A copy shaping part 11c having nearly the same shape as the end (b) of the extruding introduction part 11 is formed on the end part of an opposite side of the extruding introduction part 11b in the tooth profile forming part 11a. In this way, it is possible to work a gear free from an underfill, exact in tooth profile and high in accuracy.
