    Rotierende Ziehscheibe mit Walzen für Rohre, Stangen und dgl.   



   Die Herstellung von runden Rohren, Stangen und dgl. erfolgt für gezogene Ware in der Weise, dass das Arbeitsstück durch ein Zieheisen oder eine Ziehscheibe, die mit einer entsprechenden Öffnung versehen ist, gezogen wird, wobei der Lochdurchmesser der Ziehscheibe kleiner ist als der   Rohr- bzw. Stangendurchmesler,   so dass dieses Durchziehen eine Verjüngung des Querschnittes bewirkt. 



   Die vorliegende Erfindung ersetzt diese Ziehscheibe, die bisher feststehend in Anwendung gekommen ist, durch eine rotierende Ziehscheibe a, die vermittelst kreuzend zur Werkstückachse gestellter Bolzen b konische Walzen   tp   in sich aufnimmt. Infolge der Rotation der Ziehscheibe   a   während des Ziehens des Arbeitsstücke r wälzen sich die Walzen w um das Arbeitsstück ab. Die kreuzende Lage der Bolzen b im Vereine mit der Konizität der Walzen   w   bestimmt die Grösse der Querschnittsverminderung des Arbeitsstückes. 



   Durch vorliegende Erfindung ist es möglich, unter Aufwand einer geringeren Kraft für das Durchziehen des Arbeitsstücke bedeutendere   Querschnittsveränderungen   durchzuführen, als es unter Verwendung der feststehenden Ziehscheiben möglich gewesen ist. 



  Des weiteren wird die Oberfläche des Arbeitsstücke in glatterer und schönerer Form zutage gebracht, weil ein Gleiten der Walzen am Werkstück verhindert ist und grosse Querschnittsveränderungen unter allmählicher Einwirkung durchgeführt werden können. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

    Rotating drawing disk with rollers for tubes, bars and the like.



   Round tubes, rods and the like are produced for drawn goods in such a way that the work piece is drawn through a drawing iron or a drawing disk which is provided with a corresponding opening, the hole diameter of the drawing disk being smaller than the tube or rod diameter, so that this pulling through causes a tapering of the cross section.



   The present invention replaces this drawing disk, which has hitherto been used in a fixed manner, by a rotating drawing disk a, which accommodates conical rollers tp by means of bolts b positioned crosswise to the workpiece axis. As a result of the rotation of the drawing disk a while the work piece r is being drawn, the rollers w roll around the work piece. The intersecting position of the bolts b in conjunction with the conicity of the rollers w determines the size of the cross-sectional reduction of the workpiece.



   With the present invention, it is possible to carry out more significant changes in cross-section for pulling the work piece through with less force than was possible using the fixed pulling disks.



  Furthermore, the surface of the work piece is brought to light in a smoother and more beautiful shape, because sliding of the rollers on the workpiece is prevented and large changes in cross section can be carried out with gradual action.

PATENT ANSPRUCH : Rotierende Ziehscheibe mit Walzen für Rohre, Stangen und dgl., dadurch gekennzeichnet, dass die Walzen entsprechend der Verminderung des ! Werkstückquerschnittes konisch ausgestaltet und mit ihren Achsen kreuzend zur Ziehscheibenachse gelagert sind, zum Zwecke, ein Gleiten der Walzen am Werkstücke zu verhindern und grosse Querschnittsveränderungen unter allmählicher Einwirkung und geringerem Kraftverbrauch durchführen zu können. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Rotating drawing disk with rollers for pipes, rods and the like., Characterized in that the rollers correspond to the reduction of the! Workpiece cross-section are designed conically and mounted with their axes crossing to the drawing pulley axis, for the purpose of preventing the rollers from sliding on the workpieces and to be able to carry out large changes in cross-section with gradual action and less power consumption. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
