Procedure for manufacturing internal gear component

摘要

The preform (20) before pressing is clamped on the tool mandrel (11) in the axial direction between the pressure element (15) and a stop element (14). The free end of the cylinder wall area (22) lies on the stop element. For each moment of rotation, the roller (10) lies only on one axial section of the cylinder wall area of the preform and this is impressed into the external toothing (16). Through the roller only so much material of the preform is pressed into the external toothing so that just the tooth spaces (12) radially below the cylinder wall area are filled out and no cross section reduction takes places.
