    • Den bekannten Festwalzrollenköpfen ist gemeinsam, dass die Rollenkäfige am Gehäuse des Festwalzrollenkopfes jeweils mit L-förmigen Haltern befestigt sind. Mit Hilfe der Halter können die Rollenkäfige in eine vorgegebene Position gebracht und am Festwalzrollenkopf fixiert werden. Dabei ist vorgesehen, dass die Festwalzrollen in den jeweiligen Rollenkäfigen mit geringem Spiel lose drehbar geführt werden. Dieses Spiel beträgt in der Regel etwa 0,2 mm. Zusätzlich ist vorgesehen, dass die Festwalzrollen gegenüber der Mitte des Gehäuses des Festwalzrollenkopfes, um welche sich eine Führungsrolle für die Festwalzrollen dreht, auf der sich die Festwalzrollen gegenüber der Kurbelwelle abstützen, einen Versatz von etwa 0,2 mm haben. Darüber hinaus haben die Festwalzrollen im Festwalzrollenkopf auch noch eine Spreizung in axialer Richtung.The well-known deep rolling head is common that the roller cages on the housing of the deep rolling roller head each secured with L-shaped holders. With help The holder can roll cages in a predetermined Position brought and fixed on the deep rolling head become. It is envisaged that the deep rolling in loose the respective roller cages with little play be guided rotatably. This game is usually about 0.2 mm. In addition, it is envisaged that the Deep rolling against the center of the housing of the A deep rolling roller head around which a leading role for the deep rolling rolls on which the Support fixed rollers against the crankshaft, a Offset of about 0.2 mm. In addition, the Fixed rollers in the deep rolling head also one more Spread in the axial direction.

    Die genaue, d.h. vorgegebene Lage der Festwalzrollen im Festwalzrollenkopf ist entscheidend für deren Standzeit. Trotz genauer Einstellung tritt Verschleiß auf, der das Spiel zwischen den Festwalzrollen und den Rollenkäfigen im Verlauf des Einsatzes des Festwalzwerkzeugs vergrössert. Daraus wird erkennbar, dass der genauen Einstellung der Festwalzrollen im Festwalzrollenkopf eine besondere Bedeutung zukommt. Die Einstellung erfolgt bei den aus dem Stand der Technik bekannten Festwalzrollenköpfen über die L-förmigen Halter für die Rollenkäfige. Im günstigsten Falle gibt es für diese Einstellung Einstellehren. Üblich ist es aber auch, die Einstellung von einem geübten Fachmann von Hand vornehmen zu lassen. Dabei konnte allerdings beobachtet werden, dass die Lebensdauer der Festwalzrollen und der Rollenkäfige wesentlich von der Geschicklichkeit des einstellenden Fachmanns beeinflusst wird. Ausserdem ist das Einstellen der Festwalzrollen eine langwierige Tätigkeit, welche viel Arbeitszeit erfordert.The exact, i. specified position of the deep rolling rollers in Deep rolling head is crucial for its service life. Despite accurate setting occurs wear, which is the Play between the deep rolling rollers and the roller cages in the course of using the deep rolling tool increased. From this it becomes evident that the exact Adjusting the deep rolling rollers in the deep rolling head a particular importance. The setting is made at known from the prior art Deep rolling roller heads over the L-shaped bracket for the Roller cages. In the best case, there is for this Setting adjustment gauges. But it is also usual that Manual adjustment by a trained specialist allow. However, it was possible to observe that the life of the deep rolling rolls and the Roll cages essential of the skill of the adjusting expert is influenced. It is also Setting the fixed rollers a lengthy Activity which requires a lot of working time.

    Daraus ergibt sich die Aufgabe für die vorliegende Erfindung, einen Festwalzrollenkopf so zu verbessern, dass eine genaue Einstellung der Festwalzrollen ohne besondere Geschicklichkeit oder grossen Aufwand an Arbeitszeit möglich wird. Auch soll es möglich sein, den an den Rollenkäfigen auftretenden Verschleiss auszugleichen. Zugleich soll damit die Lebensdauer der Festwalzrollen und Rollenkäfige sowie die Qualität des festgewalzten Produktes verbessert werden. Schließlich soll die Verbesserung einfach und preisgünstig sein und auch von weniger geübten Fachkräften mit der erforderlichen Präzision durchgeführt werden können.This results in the task for the present Invention to improve a deep rolling roller head so that an accurate adjustment of the deep rolling without special skill or great effort Working time is possible. Also it should be possible, the Wear occurring on the roller cages compensate. At the same time, the life of the Fixed rollers and roller cages as well as the quality of the hard-rolled product can be improved. After all the improvement should be easy and inexpensive and even by less experienced professionals with the required precision can be performed.

    Die Aufgabe wird durch eine neuartige Ausgestaltung des Gehäuses des Festwalzrollenkopfes entsprechend den Merkmalen des Hauptanspruchs gelöst.The task is characterized by a novel embodiment of the Housing of the deep rolling roller head solved according to the features of the main claim.

    Fortan entfallen die bekannten L-förmigen Halter für die Rollenkäfige und deren aufwendig Justierung am Gehäuse des Festwalzröllenkopfes, wodurch eine wesentliche Vereinfachung erzielt wird. Durch Herunterziehen der beiden äusseren Enden der der Kurbelwelle zugewandten Stirnseite des Gehäuses des Festwalzrollenkopfes werden auf einfache Weise Anschläge zum Abstützen der Stirnseiten der beiden Rollenkäfige erhalten, welche von den Festwalzrollen abgewandt sind. Hierbei macht man sich moderne Fertigungsmethoden zu nutze, die es erlauben, zwischen den beiden Vorsprüngen der Stirnseite des Gehäuses eine passgenaue Ausnehmung zu schaffen. In dieser Ausnehmung werden sodann mit grosser Genauigkeit gefertigte Rollenkäfige eingesetzt, so dass im Ergebnis das zwischen den Rollenkäfigen und den Festwalzrollen vorgesehene Spiel von 0,2 mm eingehalten werden kann. Die modernen Fertigungsmethoden erlauben es aber auch, den seitlichen Versatz der Drehachsen der Festwalzrollen gegenüber der Drehmitte des Gehäuses des Festwalzrollenkopfes herzustellen.From now on, the known L-shaped holder for the omitted Roller cages and their elaborate adjustment on the housing the deep rolling roller head, creating a substantial Simplification is achieved. By pulling down the both outer ends of the crankshaft facing Front side of the housing of the deep rolling roller head in a simple way stops for supporting the Front sides of the two roll cages obtained, which of facing away from the fixed rollers. Here you go use modern manufacturing methods that allow between the two projections of the front side of the Housing to create a precisely fitting recess. In This recess are then with great accuracy manufactured roller cages are used, so as a result that between the roller cages and the deep rolling rollers provided clearance of 0.2 mm can be maintained. The modern manufacturing methods also allow the lateral offset of the rotary axes of the deep-rolling rollers opposite the center of rotation of the housing of To produce a deep rolling roller head.

    Bei eintretendem Verschleiß ist sodann vorgesehen, in Abhängigkeit vom jeweiligen Verschleiss zwischen den Enden des Gehäuses und den sich darauf abstützenden Stirnseiten der Rollenkäfige zusätzliche Distanzstücke einzufügen, welche, entsprechend dem festgestellten Verschleiss, eine Dicke zwischen 0,1 mm und 0,5 mm, vorzugsweise 0,2 mm haben. Nach einer weitergehenden, vorteilhaften Ausführungsform ist vorgesehen, ein oder zwei Distanzstücke in den Enden des Gehäuses des Festwalzrollenkopfes in Richtung auf die Festwalzrollen beweglich zu führen und mit Hilfe einer Feineinstellung in unterschiedlichen Positionen ein- und feststellbar zu machen. In diesem Fall wird der Verschleiss der Rollenkäfige, sobald er sich bemerkbar macht, durch Nachstellen des oder der Distanzstücke von Zeit zu Zeit auszugleichen.At incoming wear is then provided in Dependence on the respective wear between the Ends of the housing and the ones resting on it Front sides of the roller cages additional spacers which, according to the established Wear, a thickness between 0.1 mm and 0.5 mm, preferably 0.2 mm. After a further, advantageous embodiment is provided, one or two spacers in the ends of the housing of the Deep rolling roller head in the direction of the deep rolling rollers movable and with the help of a fine adjustment in different positions and lockable too do. In this case, the wear of the Roll cages, as soon as it makes itself felt through Adjusting the spacer (s) from time to time compensate.

    Durch die neue Ausgestaltung des Gehäuses des Festwalzrollenkopfes ändert sich an den Rollenkäfigen selbst nichts. Sie weisen nach wie vor auf ihrer der Kurbelwelle zugewandten Unterseite eine Längsnut auf, über welche sie von einem geeigneten Organ am Gehäuse gehalten und seitlich geführt werden. Due to the new design of the housing of Deep rolling roller head changes at the roller cages nothing himself. They still point to theirs Crankshaft facing bottom on a longitudinal groove, about which they are from a suitable organ on the housing held and guided sideways.

    Erfindungsgemäß besteht das Organ aus einer einfachen, flachen Lasche, deren eines Ende am Vorsprung des Gehäuses angeschraubt wird und deren anderes, freies Ende davon auskragend in die Nut auf der Unterseite des Rollenkäfigs eingreift. Es kann aber auch eine einzelne Lasche vorgesehen sein, die beide Rollenkäfige überbrückt und mit ihren beiden Enden am jeweiligen Vorsprung des Gehäuses des Festwalzrollenkopfes lösbar verschraubt ist.According to the invention, the organ consists of a simple, flat flap, one end of which is on the projection of the Housing is bolted and the other, free end cantilevered into the groove on the bottom of the Roller cage engages. But it can also be a single one Lug be provided which bridges both roller cages and with its two ends on the respective projection of Housing of the deep rolling roller head is releasably screwed.

    Mit diesen einfachen Mitteln entfällt fortan das zeitraubende und in seiner Genauigkeit unsichere Einstellen der Rollenkäfige mit Hilfe der bekannten L-förmigen Halter am Gehäuse des Festwalzrollenkopfes. Das zwischen dem Vorsprung und dem jeweiligen Rollenkäfig einfügbare Distanzstück kann einmal dazu dienen, wie bereits geschildert, den Versatz der Festwalzrolle herzustellen, zum anderen aber auch, den Verschleiß des Rollenkäfigs über ein gewisses Maß auszugleichen.From then on, these simple means will no longer apply time-consuming and uncertain in its accuracy Adjusting the roller cages with the help of the known L-shaped Holder on the housing of the deep rolling roller head. The between the projection and the respective roller cage insertable spacer can once serve as already described, the offset of the deep rolling roller on the other hand, the wear of the Roll cage to compensate for a degree.

    Beim Distanzstück 23 der Fig. 3 handelt es sich um einen prismatischen Körper von gegenüber der Dicke des Distanzstückes 20 der Fig. 1 wesentlich grösserer axialer Länge. Die Fig. 3 zeigt nur ein einziges Distanzstück 23, welches den angrenzenden Rollenkäfig 5 auf seiner rückwärtigen Stirnseite 10 abstützt. Analog dazu kann auch dem Rollenkäfig 6 ein gleichartiges Distanzstück entsprechend dem Distanzstück 23 zugeordnet sein.The spacer 23 of Fig. 3 is a prismatic body of opposite to the thickness of the Spacer 20 of FIG. 1 substantially larger axial Length. 3 shows only a single spacer 23, which the adjacent roll cage 5 on his rear end face 10 is supported. Analogous to this also the roller cage 6 a similar spacer be assigned according to the spacer 23.

    Wie in der Fig. 4 erkennbar, ist das Distanzstück 23 an zwei zylindrischen Zapfen 24 geführt, die im gegenseitigen Abstand 25 voneinander in Bohrungen 26 innerhalb des Vorsprungs 11 des Gehäuses 2 eingreifen. Die Zapfen 24 sind Teile des Distanzstückes 23 und mit diesem fest und unlösbar verbunden. Der Abstand 25 schafft Raum für den Eingriff der Schraube 16 für die Lasche 15 in den Vorsprung 11.As can be seen in FIG. 4, the spacer 23 is on two cylindrical pins 24 out in the mutual distance 25 from each other in holes 26th engage within the projection 11 of the housing 2. The pins 24 are parts of the spacer 23 and with this firmly and inextricably linked. The distance 25 makes room for the engagement of the screw 16 for the Tab 15 in the projection 11th

    An ihren äusseren Enden 27 werden die beiden Bohrungen 26 jeweils von Madenschrauben 28 verschlossen, deren Lage innerhalb der Bohrungen 26 vom Ende 27 her einstellbar ist. An den Madenschrauben 28 stützt sich das Distanzstück 23 mit seinen beiden Zapfen 24 ab. Durch Verstellen der Madenschrauben 28 wird die genaue Lage des Distanzstücks 23 und somit die Lage des Rollenkäfigs 5 am Gehäuse 2 des Festwalzrollenkopfes 1 eingestellt. At its outer ends 27, the two holes 26 each closed by grub screws 28, their location within the holes 26 adjustable from the end 27 ago is. At the grub screws 28 is supported Spacer 23 with its two pins 24 from. By Adjusting the grub screws 28, the exact location of Spacer 23 and thus the position of the roller cage 5 am Housing 2 of the deep rolling roller head 1 is set.

    Liegt die genaue, d.h. vorgegebene Lage des Rollenkäfigs 5 einmal fest, werden die beiden Madenschrauben 28 von einer Schraube 29 fixiert, welche über eine weiche Unterlegscheibe 30 auf die beiden Madenschrauben 28einwirkt. Die Lage des Distanzstücks 23 und somit die Lage der Rollenkäfige 5 und 6 zu den Festwalzrollen 4 wird nach Bedarf dem Verschleiss der Rollenkäfige 5 und 6 durch Verstellen der Madenschrauben 28 und Feststellen der Schraube 29 angepasst. If the exact, i. predetermined position of the roller cage Once fixed, the two grub screws 28 of a screw 29 fixed, which via a soft Washer 30 on the two grub screws 28einwirkt. The location of the spacer 23 and thus the Location of the roller cages 5 and 6 to the fixed rollers 4 If necessary, the wear of the roller cages 5 and 6 by adjusting the grub screws 28 and locking adapted to the screw 29.
