Description

Verfahren zur Herstellung von Radscheiben und Radsternen. Gegenstand der Erfindung bildet ein Verfahren zur Herstellung von Radscheiben und Radsternen durch Stauchung von Teilblöcken eines im Walzwerk kantig oder rund bis auf einen so geringen Durchmesser heruntergewalzten Gußblockes, daß der zu einer Radscheibe oder einem Radstern erforderliche Teilblock eine Länge besitzt, welche ein Mehrfaches der Höhe des Fertigerzeugnisses beträgt.Process for the production of wheel disks and wheel spiders. object the invention forms a method for producing wheel disks and wheel spiders by upsetting partial blocks in the rolling mill, edged or round except for one so small diameter rolled cast ingot that it becomes a wheel disc or a wheel spider required partial block has a length which is a multiple the height of the finished product.

Die Produkte der verschiedenen Verfahrensstufen sind in Fig. i bis 7 veranschaulicht. Zunächst wird der in Fig. i dargestellte größere Block gegossen, welcher für eine Mehrzahl von Radscheiben ausreicht. Dieser Block wird auf Teilblockgröße in runder Form, ungefähr dem Durchmesser der Radscheibennabe entsprechend, vorgewalzt (Fig. 2) und auf der Schere oder auf der Säge warm im normalen Fabrikationsgange unterteilt, wodurch die Teilblöcke (Fig. 3) entstehen. Hierauf folgt dann das Stauchen unter der Presse oder dem Hammer, wodurch das in Fig. ¢ dargestellte Arbeitsstück entsteht, dann das Lochen (Fig. 5), die Auswalzung auf dem Radscheibenwalzwerk (Fig. 6) und schließlich die endgültige Formgebung durch Kümpelung (Fig. 7). Die Figuren lassen erkennen, daß die Blöcke für die einzelnen Radscheiben stets lunkerfrei sind, so daß auch das Endprodukt frei von Lunker sein muß. Für die Güte des Endprodukts kommt auch in Betracht, daß der gestauchte Block gemäß Fig. q. bereits vorher durch Auswalzung des großen Blockes nach Fig. i eine Durcharbeitung erfahren hat, also schon ein dichteres Gefüge besitzt, ehe er dem Stauchprozeß behufs Bildung des in Fig. q. dargestellten Arbeitsstückes 'unterworfen wurde. Was im vorstehenden für Radscheiben gesagt ist, gilt auch für Radsterne oder Speichenräder.The products of the various process steps are shown in FIGS 7 illustrates. First, the larger block shown in Fig. I is cast, which is sufficient for a plurality of wheel disks. This block is set to partial block size Pre-rolled in a round shape, roughly corresponding to the diameter of the wheel disc hub (Fig. 2) and on the scissors or on the saw warm in the normal manufacturing process divided, whereby the sub-blocks (Fig. 3) arise. This is then followed by upsetting under the press or the hammer, whereby the work piece shown in Fig then the punching (Fig. 5), the rolling on the wheel disc rolling mill (Fig. 6) and finally the final shaping by dishing (Fig. 7). The figures show that the blocks for the individual wheel disks are always free of voids, so that the end product must also be free of voids. For the quality of the end product It is also possible that the compressed block according to FIG. q. through beforehand Rolling out the large block according to Fig. I has been worked through, so already has a denser structure before it is subjected to the upsetting process for the formation of the in Fig. Q. illustrated work piece 'was subjected. What in the foregoing Wheel disks is said, also applies to wheel stars or spoked wheels.
