摘要： A method for producing steel rolling bearing rings, starting from a hot-rolled tube, the structure of which is similar to a spheroidized structure and from which rings of the same continuous length are hot-cut while supplying a lubricant and, after cooling, are further processed. The hot-cutting takes place at a temperature below the transformation temperature of the rolling bearing steel used but above 720° C., with subsequent cooling in static air. From the blank ring a green or soft ring of a rolling bearing ring is produced with narrow tolerances of its shaped elements by an optimally timed multistage machining type of cold further processing operation, the main element of the cold further processing being a turning operation.

摘要： Apparatus for the continuous, chipless separation of individual, identical pieces from a solid round workpiece, includes at least two cutting rollers, cooperating with one another, for separating and rolling the workpiece. Each of the cutting rollers is defined by a separating portion and has a coil, with the height of the coil of one cutting roller being equal or slightly greater than the radius of the workpiece in the separating portion, and with the coil of the other cutting roller so configured as to eliminate a collision in the separating portion with the coil of the one cutting roller.

摘要： A parting tool for continuous chipless separation of identical parts from a rotation-symmetric workpiece, includes a cutting roller having a main body advancing a workpiece in a transport direction from an entry side to an exit side. The main body has a slip bevel at the entry side and a cutting screw including a screw thread having coils which define a helix line and are configured with an increase in height. The screw thread includes in series an entry portion, a substantially cylindrical primary portion and a separating portion, whereby the coils in the entry portion, primary portion and separating portion having different slope angle, with the slope angle determined by a combination of a thickness of the screw thread and a root width between two neighboring coils of the screw thread, wherein the increase in height of the coils correlates to the helix line.

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.
