Description

Walze, insbesondere Abstützwalze, für Kaltwalzwerke Es sind Walzen bekannt, bei denen auf einen Kern ans verhältnismäßig weichem; zähem Werkstofft einzelne Ringe mit hoher Oberflächenhärte als Mantel aufgeschrumpft oder in sonst geeigneter Weise befestigt werden. Diese -einzelnen Ringe stoßen stumpf gegeneinander. Dadurch ist mit Sicherheit eine einwandfreie Oberfläche nicht zu erzielen, wie es für- Wälzen, @ irsbAöndere Abstütz= walzen, für hochbeanspruchte Kaltwalzwerke Bedingung ist. Eine solche vollständige Yerfestigung der einzelnen Ringe zu einer Einheit wird erfindungsgemäß durch die Ausbildung der Stoßflächen der Walzenringe als Kegel oder Hohlkegel erreicht. In der Zeichnung ist das Wesen der Erfindung dargestellt. Fig. t und 3 stellen Längsschnitte durch eine Walze gemäß der neuen Erfindung, Fig. 2 und :l Querscbnitte zweier verschiedener Ausführungsformen dar. In den Abbildungen bedeutet i und 3 den Kern aus zähem und verhältnismäßig weichem Werkstoff. 2 und 4 sind die einzeln aufgesetzten Ringe, die mit kegel- und hohlkegelartigen `Flächen an den Stoßstellen versehen sind. Die einzelnen Ringe werden durch einen Schrumpfring 5 gehalten. Bei Fig. i sind die Stoßflächen Kegel und Hohlkegel. Bei Fig. 3 laufen diese' Tiegel oder Hflhlkegel innen und außen abgestumpft aus. Die Innenfläche der Ringe kann' glatt oder mit Nuten versehen sein, wie es die Querschnitte Abb. 2 und 4-darstellen.. In gleicher Weise können auch die Arbeitswalzen für Kaltwalzwerke ausgebildet sein. @,Roll, especially support roll, for cold rolling mills There are rolls known to have a core that is relatively soft; tough material individual rings with high surface hardness shrunk on as a jacket or otherwise be attached in a suitable manner. These individual rings butt against each other. As a result, a perfect surface cannot be achieved with certainty, as it is for rolling, @ irsbAöndere support = rolling, condition for highly stressed cold rolling mills is. Such a complete consolidation of the individual rings into a unity is according to the invention by the design of the abutting surfaces of the roller rings as a cone or hollow cone. The essence of the invention is shown in the drawing. Fig. T and 3 show longitudinal sections through a roller according to the new invention, Fig. 2 and: 1 show cross-sections of two different embodiments. In the figures i and 3 mean the core made of tough and relatively soft material. 2 and 4 are the individually attached rings with conical and hollow cone-like `surfaces are provided at the joints. The individual rings are held in place by a shrink ring 5 held. In Fig. I the abutment surfaces are cones and hollow cones. Run at Fig. 3 These 'crucibles or hollow cones are truncated inside and out. The inner surface of the Rings can be 'smooth or grooved, as shown in the cross-sections Fig. 2 and 4-represent .. In the same way, the work rolls for cold rolling mills be trained. @,
