Description
<Desc/Clms Page number 1>
Walzwerk zur fortlaufenden Herstellung von senkrecht aufsteigenden Quervorsprüngen an stabartigen Metallstücken.
Die Erfindung bezieht sich auf eine weitere Ausbildung des Walzwerkes nach dem Patent 134951, bei welchem das Vorwerkstück zwischen einer Oberwalze und einem als unteres Walzwerkzeug dienenden Tisch, der die örtlichen Vertiefungen oder Erhebungen enthält, hindurchgeführt wird.
Es hat sich nämlich gezeigt, dass beim Walzen von Profilstäben vorerwähnter Art bei gleicher Umfangsgeschwindigkeit der Walze wie der Geschwindigkeit des Walztisches Verdrückungen, Verzerrungen, Verwerfungen u. dgl. des Profils zwischen den Rippen, Nocken oder sonstigen Verstärkungen eintreten, die die einwandfreie Beschaffenheit des Endproduktes beeinträchtigen.
Es wurde nun erfindungsgemäss festgestellt, dass ein einwandfreier Profilstab dadurch hergestellt werden kann, dass man dem die geradlinige Bewegung ausführenden Walztisch eine grössere Geschwindigkeit erteilt, als der Umfangsgeschwindigkeit der Walze entspricht. Es wurde beispielsweise beim Walzen von Stäben aus Eisen mit Querprofilen festgestellt, dass, wenn der Tisch eine gegenüber der Umfangsgeschwindigkeit der Oberwalze um 25% grössere Geschwindigkeit aufwies, das Arbeitsstück in durchaus einwandfreiem Zustande aus der Matrize des Tisches herausgenommen werden konnte. Die Grösse der Mehrgeschwindigkeit ist durch Versuch bei den einzelnen Metallen, aus denen die Werkstücke bestehen, leicht festzustellen.

Rolling mill for the continuous production of vertically rising transverse projections on rod-like metal pieces.
The invention relates to a further embodiment of the rolling mill according to patent 134951, in which the preliminary workpiece is passed between an upper roll and a table which serves as a lower rolling tool and which contains the local depressions or elevations.
It has been shown that when rolling profile bars of the type mentioned above, at the same circumferential speed of the roll as the speed of the roll table, displacements, distortions, warps and the like. Like. Of the profile occur between the ribs, cams or other reinforcements that affect the proper quality of the end product.
It has now been found according to the invention that a flawless profile bar can be produced by giving the roller table executing the linear movement a speed greater than the peripheral speed of the roller. For example, when rolling iron bars with transverse profiles, it was found that when the table had a speed 25% higher than the peripheral speed of the top roller, the workpiece could be removed from the die of the table in perfectly good condition. The magnitude of the excess speed can easily be determined by testing the individual metals of which the workpieces are made.
