摘要

A method for cold rolling of a longitudinally directed teeth and profiles in the case of long shaft-like workpieces by means of one tech rolls with a shape mill that is provided with incremental round rolling tools (3), which at its circumference and subsequently vorrollzähne to this a plurality of concentric to the axis of the roller have finished roll teeth, the profiles of the successive vorrollzähne the profile of the finished roll teeth progressively approach each other, characterized in that a longitudinally directed profile or tooth system in a plurality of axially advancing part sections is rolled, wherein, in a first working step a first toothed section (13) is provided with synchronously rotationally driven round rolling tools (3) is rolled and, in a second and each of the following first working step, a second profile section and further sections are being rolled, wherein the rolling and setting in place in the anwalzbereich (7) in a transition region (15) between the anwalzbereich (7) and a sizing section (8) of the round rolling tools (3) is carried out in such a way that one of the round rolling tools (3) separately with a freely controllable rolling carriage with a swinging circumferential movement (16) with partial overlap of the first toothing section (13), until reaching the workpiece contact is placed, after which the round rolling tool (3) with the reaching of the workpiece contact with the workpiece (5) into the initial position of the anwalzbereichs (7) is moved back, the second round rolling tool (3) and fed to the rolling process of the second profile section and each further section is carried out.
