With a newly developed ring roller, Schuler now offers complete production lines for the manufacturing of rings from a single source.

From heating and automation systems to forging presses and dies: Schuler has already implemented a large number of projects in ring preform production with great success. With its new series of ring rollers developed in close cooperation with the forging industry, the world market leader in forming technology now provides complete production lines from a single source. Schuler is presenting the machine for the first time at the EMO trade fair in Hanover, Germany (Hall 15, Booth E29), from September 18 to 23.

In the process, the developers have come up with a number of special features that directly benefit customers. The position of the upper bearing of the mandrel, for example, can be adjusted in height. Therefore the length of the roller mandrels can be adapted exactly to the ring geometry, which leads to considerably reduced bending and die loads. Through an additional roller mandrel drive, all forming dies can also rotate during idle times, thus cooling evenly on all sides.

The innovative machine concept with a comparably low construction height also improves accessibility for a quick change of the roller mandrel. In combination with the main roller in a cartridge design, a die change is possible in just a few minutes. Due to the short equipping times and high technical availability, Schuler therefore also offers an economical solution for the production of small lot sizes.

The new series is designed for ring sizes with outer diameters up to 8,000 millimeters and heights up to 1,250 millimeters. At EMO, Schuler is introducing a machine for rings with a diameter of 4,000 millimeters and a height of 1,000 millimeters. For the drive of the main roller, two motors with an output of 500 kilowatts each and taper rollers with 500 kilowatts have been provided. Customized machines with stronger drives for special materials or lager ring are also possible, of course.
