摘要： When forming a toothed portion on the outer section of a blank by contacting a tooth profile-forming portion of a forming die with a curved portion of the blank, the first projection of the blank is accommodated in a first depression, and a load is applied axially to a center section of the blank so a material of the blank flows radially outward. The material of the blank at the first projection flows in the axial direction to inside the first depression, and the material of the blank at an intermediate section between the center and the outer section flows in axially to inside a second depression to form a second projection. When the load is maximized, a space is provided between a toothed portion and the tooth profile-forming portion, between the first projection and the forming die, and between the second projection and the forming die.

摘要： A method for manufacturing a toothed part from a cylindrical blank using a forming die. When forming a toothed portion on a radially outer section of the blank by applying a load in the axial direction of the blank to a radially center section of the blank while constraining a portion of an outer circumferential surface of the blank such that a constituent material of the blank flows radially outward, the constituent material of the blank at an intermediate section between the center section and the outer section flows in the axial direction toward a depressed portion of the forming die to form a projection portion. When the load is at maximum, a space is provided between the toothed portion and the forming die, and a space is provided between the projection portion and the forming die.
摘要翻译：一种使用成形模从圆柱形坯料制造齿形部件的方法。当通过在坯料的轴向方向上施加负载到坯料的径向中心部分上而在坯料的径向外部部分上形成齿形部分时，同时限制坯料的外周表面的一部分，使得坯料的构成材料坯料沿径向向外流动，在中心部分和外部部分之间的中间部分处的坯料的构成材料沿轴向朝着成形模具的凹陷部分流动以形成突出部分。当载荷最大时，在齿形部分和成型模具之间设置空间，并且在突出部分和成形模具之间设置一个空间。
