Description
Verfahren und yGüß orm zur Herstellung von Hohlblöcken durch Schleuderguß. Es ist vorgeschlagen, durch Scldeuderguß gewonnene Hohlkörper auf dem Wege des Auswalzens zu Rohren großer Länge und mehr oder weniger geringer Wandstärke umzuformen. Diese Hohlkörper hatten bisher zylindrische Form.Process and yGüß form for the production of hollow blocks by centrifugal casting. It is proposed that hollow bodies obtained by spin-casting be rolled out to form pipes of great length and more or less thin walls. These Hollow bodies previously had a cylindrical shape.
Die Aufnahme dieses stumpfen Körpers durch die Walze begegnet insofern Schwierigkeiten, als die letzteren das Stück schlecht zu fassen vermögen. Insbesondere ist dies beim Pilgerschrittwalzwerk der Fall. Man behilft sich damit, daß man den Walzenstich geringer nimmt, wodurch aber die Auswalzfähigkeit des Walzwerkes nicht voll ausnutzbar ist. Man könnte einen viel kräftigeren Such geben, also beim Durchgang durch die Walzen erheblich mehr Material verdrängen und das Rohr in weniger Arbeitsgängen fertig bekommen, wenn es möglich wäre, zu erreichen, daß der Hohlkörper von den Walzen bei der Einführung zwischen sie leichter gefaßt würde.This counteracts the absorption of this blunt body by the roller Difficulties when the latter are unable to grasp the piece badly. In particular this is the case with the pilgrim step rolling mill. One makes do with the fact that one Roll pass takes less, but this does not reduce the rolling capacity of the rolling mill is fully exploitable. One could do a much more powerful search, that is, when passing through The rollers displace considerably more material and the pipe in fewer work steps get ready if it were possible to achieve that the hollow body of the Rolling would be more easily grasped at the introduction between them.
Gemäß der vorliegenden Erfindung wirrd dies dadurch bewirkt, daß man den Hohlblock mit sich verjüngenden Enden gießt. Es kann aber auch genügen, nur ein Ende desselben in dieser Weise zu formen.According to the present invention, this is accomplished by pours the hollow block with tapered ends. But it can also be enough, just to shape one end of it in this way.
Abb. i der Zeichnung stellt einen solchen Hohlkörper im Längsschnitt dar. Abb. 2 zeigt beispielsweise die zugehörige Ausbildung der Gießform.Fig. I of the drawing shows such a hollow body in longitudinal section Fig. 2 shows, for example, the associated design of the casting mold.
An den Enden der Schleuderform. a sind Ab.schlußringe b eingesetzt, welche den Gießraum nach außen kegelig begrenzen.At the ends of the centrifugal mold. a closing rings b are used, which delimit the casting space conically to the outside.
Statt .der reinen Konusform kann auch eine kantig konische Form gewählt werden, oder irgendeine andere mit der Kernzeichnung, daß die geraden oder gebrochenen oder gewellter. Mantellinien an den Enden der Form gegen deren Achse geneigt sind. Je nachdem man diese Zuspitzung wählt, ob man gering oder in großem Maße zuschärft, wirkt sie nicht nur beim ersten Walztisch, sondern auch in mehr oder wenigen folgenden Stichen.Instead of the pure conical shape, an angular conical shape can also be selected be, or any other with the core drawing that straight or broken or more wavy. Generating lines at the ends of the mold are inclined against its axis. Depending on whether you choose this sharpening, whether you sharpen slightly or to a large extent, it works not only on the first roller table, but also in more or a few subsequent ones Stitches.
