Description

Es ist bekannt, die einzelnen Kaliberteile eines sich aus mehreren Walzen zusammensetzenden Kalibers auf das gewünschte Rundkaliber ein:zustellen, indem die Lagerkörper eines jeden Teilkalibers um Achsen schwenkbar geilagert sind, die in gleichen Abständen und symmetrisch um die Walzenachse sowie parallel zu dieser verlaufend angeordnet sind. Es ist fernerhin bekannt, die Teilkaliber jedes einzelnen Rundkalibers durch eine ihnen gemeinsame Verstellvorrichtung zu betätigen.It is known that the individual caliber parts are one of several Rolls of the composing caliber to the desired round caliber: adjust, in that the bearing bodies of each sub-caliber are supported so that they can pivot about axes, equidistant and symmetrical about the roller axis and parallel to it are arranged to run. It is also known, the part caliber of each To operate round caliber by an adjustment device common to them.

Es besteht die Forderung, die einzelnen Kaliber in Richtung der Walzachse möglichst nahe aneinanderzurücken. Dies ist nur dann zu erreichen. wenn der bauliche Aufwand, der für jedes Kaliber erforderlich ist, möglichst gering ist. Es ist also stets der einfachsten Vorrichtung für die Einstellung der Kaliber der Vorzug zu geben. Weiterhin muß die Bedienung der Vorrichtung von Umfangsstellen des die Einzelkaliber zusammenfassenden Gehäuses aus vorgenommen werden können, da die Bedienungselemente, die an den Stirriflächen der Gehäuse angeordnet sind, e,ine ung el gewollte Vergrößerung des Ahstandes der einzelnen Kaliber erforderlich machen.There is a requirement that the individual calibers in the direction of the rolling axis move as close together as possible. This can only be achieved then. if the structural The effort required for each caliber is as low as possible. So it is The simplest device for setting the caliber is always preferred give. Furthermore, the operation of the device from the circumference of the individual caliber summarizing housing can be made, since the controls, which are arranged on the stirrup surfaces of the housing, e, ine ung el deliberate enlargement of the state of the individual calibers.

Die bisher bekanntgewordenen Vorrichtungen entsprechen diesen Forderungen nur unvollkommen. Die Erfindung schafft hier Abhilfe.The devices that have become known so far meet these requirements only imperfect. The invention provides a remedy here.

Gemäß der Erfindung wird vorgeschlagen, die Lagergehäuse, diein. bekannter Weise um in gleichen Abständen und symmetrisch um die Walzachse lind parallel zu dieser angeordnete Achsen schwenkbar gelagert sind, durch einen drehbaren konzentrisch zur Walzachse liegenden Verstellring zu verschwenken, wobei der Verstellring mit einer der Zahl der Lagergehäuse entsprechenden Anzahl von gleichb mäßig ansteigenden Kurven. an seinem Innen durchmesser versehen ist, gegen die sich Arme der vorzugsweise unter Federdruck stehenden Lagergehäuee abstützen. je nach der Drehung des an einem Teil seines Umfanges gezahnten Verstellringes, z. B.,durch Schnecke, kann das Kaliber durch Einwirkung der Kurvenkeilflächen vergrößert oder verkleinert werden.According to the invention it is proposed that the bearing housings, which in. better known Way around equally spaced and symmetrical about the rolling axis lind parallel to these arranged axes are pivotably mounted by a rotatable concentric to pivot the adjusting ring lying to the rolling axis, the adjusting ring with a number of equally increasing numbers corresponding to the number of bearing housings Curves. is provided on its inner diameter, against which arms are preferably Support the bearing housing under spring pressure. depending on the rotation of the one Part of its circumference toothed adjusting ring, for. B., by snail, the caliber can be enlarged or reduced by the action of the curved wedge surfaces.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Abb. A stelltdie Anstellvorrichtung mit beispielsweise vier Teilkalibern dar; die Anzahl der Teilkaliber kann aber auch größer oder kleiner sein; Abb. B zeigt die Anstellvorrichtung mit geöffnetern Kaliber; Abb. C zeigt -einen Schnitt nach a-b durch -das geteilte Gehäuse; Abb. D veranschaulicht den gezahnten, drehbaren Verstellring mitden Kurvenkeilflächen.Fig. A shows the adjusting device with, for example, four partial calibers; however, the number of part calibres can also be larger or smaller; Fig. B shows the adjusting device with the caliber open; Fig. C shows a section through the divided housing; Fig. D illustrates the toothed, rotatable adjusting ring with the cam wedge surfaces.

Die Lagerkörper i der Teilkaliber sind mit Armen 2 versehen, welche sich gegen die Kurvenkeilflächen 3 des drehbaren, verzahnten Verstellringes 4 stützen. Die auf den Armen 2 des Lagerkörpers i der Teilkaliber =geordneten Federbüchsen. 5 wirken auf die festen Drehpunkte 6 und sorgen für die dauernde Verbindung der Stützarme 2 mit den Kurvenkeilflächen 3. Das Gehäuse ist geteilt und, besteht aus den einander gleichen Hälften 7 und 8. The bearing bodies i of the partial calibers are provided with arms 2 which are supported against the cam surfaces 3 of the rotatable, toothed adjusting ring 4. The spring sleeves arranged on the arms 2 of the bearing body i of the partial caliber =. 5 act on the fixed pivot points 6 and ensure the permanent connection of the support arms 2 with the curved wedge surfaces 3. The housing is divided and consists of the same halves 7 and 8.

In ge#nügend kräftiger Ausführung eignetsich die Anstellvorrichtung auch zum Walzen von Rohren über einen. Dorn im kontinuierlichen Walzwerk oder zum Pilgern von, Rohren.The adjusting device is suitable if it is sufficiently strong also for rolling pipes over a. Mandrel in the continuous rolling mill or for Pilgrimage from, pipes.
