Method for producing metallic, non-rotationally symmetrical rings with a constant wall thickness over their circumference |
摘要 |
The invention is directed to a method and a device for producing metal, non-rotationally symmetric rings with a constant wall thickness along their circumference, particularly cam rings, starting from a hot-rolled pipe from which individual portions are severed, mechanically machined and subsequently hardened and tempered. Ring blanks of equal width are severed from the pipe and are mechanically machined on all sides, and the non-rotationally symmetric shape is produced by cold forming, the pipe or the severed ring blank having a structure suitable for cold forming.
