ABSTRACT:
A cold rolling method wherein the workpiece is advanced along its lengthwise axis and rotated in pulsating fashion, in accordance with a sinusoidal-like rotational speed-time diagram, while its surface is machined during briefly effective individual rolling or generating operations by means of generating rolls seated in roller or rolling heads. Each rolling operation is accomplished when the rotational speed of the workpiece is at the lower reversal region of the aforementioned diagram. The cold rolling machine comprises a worm gear for rotating the workpiece together with its clamping or chucking device, the worm gear being seated upon the chucking device. The related worm is mounted in a displaceable carriage. This carriage is moved to-and-fro by an eccentric drive or equivalent structure, and the action of the worm is superimposed upon the worm gear and there is formed the sinusoidal-like course of the rotational speed as a function of time.
