摘要
In a method for manufacturing outer parts of constant velocity joints by plastic deformation of a preform (3) having a cavity open on one side to produce axial non-undercut ball tracks (6) and cage guide surfaces (7), wherein the preform (3) is received in an outer tool (2) and the inner tool (1) plastically forms inner wall regions to ball tracks (6) and cage guide surfaces (7) with the application of pressure, the inner tool (1) comprises a one-piece wobble pressing die having segments of diffrent convex curvature which is first of all plunged centrally into the cavity in the preform (3), after which the desired final contours of the ball tracks (6) and cage guide surfaces (7) are produced using multiple wobbling movements with a corresponding orbital angle alpha .
