PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung betrifft eine Walzenanordnung zum Auswalzen von Profilleisten, besonders hochschenkeligen, in einem Arbeitsgange.The present invention relates to a roller arrangement for rolling profile strips, especially high-legged, in one Operations.
In der Zeichnung ist als Ausführungsbeispiel ein entsprechendes Walzenpaar für ein hochschenkeliges Profil dargestellt, c ist dieses Profilwerkstück. Die Walzen sind mehrteilig. Die beiden mittleren Walzenteile β und f besitzen gleichen Durchmesser und sitzen fest auf den Achsen α und b, dagegen besitzen die seitlichen Walzenteile g und h verschiedenen Durchmesser zueinander und laufen frei mit.In the drawing, a corresponding pair of rollers for a high-legged profile is shown as an exemplary embodiment, c is this profile workpiece. The rollers are made up of several parts. The two middle roller parts β and f have the same diameter and sit firmly on the axes α and b, whereas the side roller parts g and h have different diameters to each other and run freely.
Wären diese Profilwalzen im ganzen aus einem Stück hergestellt, so entstände an den Druckpunkten d und k k ein Zerren des Materials, wodurch das Profil ungünstig beeinflußt werden würde. Man hat daher bisher derartige Profile in mehreren Arbeitsgängen herstellen oder durch verschiedene Walzen hintereinander gehen lassen müssen.If these profile rollers were made from one piece as a whole, the material would pull at pressure points d and kk , which would adversely affect the profile. It has therefore hitherto been necessary to produce such profiles in several operations or to pass them through different rollers one behind the other.
Sind dagegen die Walzen, wie nach vorliegender Erfindung, mehrteilig, und laufen nur die Teile gleichen Durchmessers zwangläufig als Zugwalzen, dann laufen die Teile verschiedenen Durchmessers lediglich durch Reibung je nach der Abwicklung des jeweiligen Profils mit. Ein Zerreißen des Materials findet dann nicht mehr statt, und das Auswalzen kann mit einem Walzenpaare und in einem Arbeitsgange erfolgen.If, on the other hand, the rollers, as according to the present invention, are made up of several parts, and run only the parts of the same diameter necessarily act as pull rollers, then the parts run different diameter only by friction depending on the development of the respective Profile with. The material is then no longer torn and rolled out can be done with a pair of rollers and in one operation.
