Ein Festwalzrollenkopf dieser Art ist aber auch Gegenstand der älteren deutschen Patentanmeldung DE 102 18 703.7 vom 26.07.2002 derselben Anmelderin.A deep rolling roller head of this type is also the subject of the older German patent application DE 102 18 703.7 from July 26, 2002 by the same applicant.
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 seitlichem 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, in der Drehrichtung der Kurbelwelle einen Versatz von etwa 0,2 mm haben. Darüber hinaus haben die Festwalzrollen im Festwalzrollenkopf auch noch eine Spreizung in axialer Richtung.The known deep rolling roller heads have in common that the roller cages are each attached to the housing of the deep rolling roller head with L-shaped holders. With the help of the holder, the roller cages can be brought into a predetermined position and fixed to the deep rolling roller head. It is provided that the deep rolling rollers in. the respective roller cages can be loosely rotated with little lateral play. This game is usually about 0.2 mm. In addition, it is provided that the deep rolling rollers in relation to the center of the housing of the deep rolling roller head, around which a guide roller for the deep rolling rollers rotates, on which the deep rolling rollers are supported with respect to the crankshaft the crankshaft has an offset of about 0.2 mm. In addition, the deep rolling rollers in the deep rolling roller head also have an expansion 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, aber auch das Nachstellen bei eingetretenem Verschleiß, 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 daneben 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.e. The predefined position of the deep rolling rollers in the deep rolling roller head is decisive for their service life. Despite the precise setting, wear occurs which increases the play between the deep rolling rollers and the roller cages in the course of the use of the deep rolling tool. From this it can be seen that the precise setting of the deep rolling rollers in the deep rolling roller head is of particular importance. The setting, but also the readjustment in the event of wear, takes place in the deep rolling roller heads known from the prior art via the L-shaped holders for the roller cages. In the best case, there are setting gauges for this setting. It is also customary to have the adjustment carried out by hand by a skilled specialist. However, it could be observed that the service life of the deep rolling rollers and roller cages is significantly influenced by the skill of the hiring specialist. In addition, setting the deep rolling rollers is a lengthy task, which requires a lot of work.
Daraus ergibt sich die Aufgabe für die vorliegende Erfindung, einen Festwalzrollenkopf so zu verbessern und insbesondere die Ausgestaltung des Rollenkäfigs soweit zu vereinfachen, dass eine genaue Einstellung der Festwalzrollen ohne besondere Geschicklichkeit oder großen Aufwand an Arbeitszeit möglich wird. Auch soll es möglich sein den 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 object of the present invention to improve a deep rolling roller head and, in particular, to simplify the design of the roller cage to such an extent that precise setting of the deep rolling rollers is possible without special skill or great expenditure of working time. It should also be able to compensate for wear. At the same time, the service life of the deep rolling rollers and roller cages and the quality of the rolled product should be improved. After all, the improvement should be simple and inexpensive and should also be able to be carried out by less experienced specialists with the required precision.
Die Aufgabe wird durch eine neuartige Ausgestaltung des Gehäuses des Festwalzrollenkopfes und damit einhergehend eine neuartige Ausgestaltung des Rollenkäfigs entsprechend den Merkmalen des Hauptanspruchs gelöst.The object is achieved by a novel design of the housing of the deep rolling roller head and, along with this, a novel design of the roller cage in accordance with the features of the main claim.
Fortan entfallen die bekannten L-förmigen Halter für die Rollenkäfige und deren aufwendig Justierung am Gehäuse des Festwalzrollenkopfes, 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 äußeren Stirnseiten des Rollenkäfigs erhalten. 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 wird sodann der mit großer Genauigkeit -gefertigte Rollenkäfig eingesetzt, wobei das zwischen dem Rollenkäfig und den Festwalzrollen erforderliche Spiel von 0,2 mm bereits vorhanden ist. Die modernen Fertigungsmethoden sowie die Ausgestaltung des Rollenkäfigs erlauben es zusätzlich auch, den seitlichen Versatz der Drehachsen der Festwalzrollen gegenüber der Drehmitte des Gehäuses des Festwalzrollenkopfes herzustellen. Die Ausnehmung auf der Unterseite des Gehäuses des Festwalzrollenkopfes wird einfach um den Betrag des Versatzes von etwa 0,2 mm in der Drehrichtung der Kurbelwelle gegenüber der Mitte des Gehäuses verschoben.From now on, the known L-shaped holders for the roller cages and their complex adjustment on the housing of the deep rolling roller head are omitted, thereby achieving a significant simplification. By pulling down the two outer ends of the end face of the housing of the deep rolling roller head facing the crankshaft, stops for supporting the outer end faces of the roller cage are obtained in a simple manner. This makes use of modern manufacturing methods that allow a precisely fitting recess to be created between the two projections on the front of the housing. The roller cage manufactured with great accuracy is then inserted into this recess, the clearance of 0.2 mm required between the roller cage and the deep-rolling rollers already being present. The modern production methods and the design of the roller cage also allow the lateral offset of the axes of rotation of the deep rolling rollers relative to the center of rotation of the housing of the deep rolling roller head manufacture. The recess on the underside of the housing of the deep rolling roller head is simply shifted by the amount of the offset of approximately 0.2 mm in the direction of rotation of the crankshaft relative to the center of the housing.
Bei eintretendem Verschleiß ist sodann vorgesehen, den Rollenkäfig einfach herumzudrehen, so dass nunmehr die weniger verschlissenen Führungsnuten des einstückigen Rollenkäfigs zum Einsatz kommen.When wear occurs, it is then provided that the roller cage is simply turned around so that the less worn guide grooves of the one-piece roller cage are used.
Durch die neue Ausgestaltung erhält man nunmehr einen einzigen einstückigen Rollenkäfig für eine oder zwei Festwalzrollen, je nach Einsatzfall, anstelle von zwei Rollenkäfigen, wie das bisher üblich war. Einstückig heißt, dass die beiden voneinander getrennten Festwalzrollenkäfige herkömmlicher Art nunmehr zu einem einzigen Werkstück zusammen gefasst sind, das in die Ausnehmung zwischen den Vorsprüngen auf der Unterseite des Gehäuses des Festwalzrollenkopfes mitsamt der einen oder der beiden Festwalzrollen nur noch hineingeschoben und befestigt werden braucht. Dabei weist der Rollenkäfig nach wie vor auf seiner der Kurbelwelle zugewandten Unterseite eine Längsnut auf, über welche er von einem geeigneten Organ am Gehäuse gehalten und seitlich geführt wird.The new design now provides a single, one-piece roller cage for one or two deep-rolling rollers, depending on the application, instead of two roller cages, as was previously the case. One piece means that the two separate deep roller cages of a conventional type are now combined into a single workpiece, which only needs to be pushed and fastened into the recess between the projections on the underside of the housing of the deep roller head together with one or the two deep rollers. The roller cage still has a longitudinal groove on its underside facing the crankshaft, via which it is held on the housing by a suitable organ and guided laterally.
Erfindungsgemäß besteht das Organ aus einer einfachen, flachen Lasche, deren beide Enden .an den Vorsprüngen des Gehäuses angeschraubt werden und deren freie Mitte in eine Nut auf der Unterseite des Rollenkäfigs eingreift. Anstelle einer Lasche können aber auch zwei Stifte vorgesehen sein, von denen jeweils einer in einem der beiden Vorsprünge auf der Unterseite des Gehäuses vorgesehen ist, die beide in Richtung ihrer Längsachse verstellbar sind und mit einem ihrer beiden Enden jeweils in eine entsprechende Ausnehmung auf den äußeren Stirnseiten des Rollenkäfigs eingreifen und an den jeweiligen VorSprüngen lösbar verschraubt sind.According to the invention, the organ consists of a simple, flat tab, the two ends of which are screwed onto the projections of the housing and the free center of which engages in a groove on the underside of the roller cage. Instead of a tab, two pins can also be used be provided, one of which is provided in one of the two projections on the underside of the housing, both of which are adjustable in the direction of their longitudinal axis and engage with one of their two ends in a corresponding recess on the outer end faces of the roller cage and on the respective Projections are detachably screwed.
Mit diesen einfachen Mitteln entfällt fortan das zeitraubende und in seiner Genauigkeit unsichere Einstellen von Rollenkäfigen mit Hilfe der bekannten L- förmigen Halter am Gehäuse des Festwalzrollenkopfes.With these simple means, the time-consuming and uncertain accuracy of the setting of roller cages with the help of the known L-shaped holder on the housing of the deep rolling roller head is eliminated.

Die Unterseite 3 des Gehäuses 2 ist der Kurbelwelle 21 zugewandt, von der die Fig. 1 den Schnitt durch ein beliebiges Hauptlager zeigt, deren Lagerzapfen jeweils seitlich von Radien oder Einstichen 22 begrenzt werden. In diese Radien oder Einstiche 22 greifen Festwalzrollen 4 ein, welche ihrerseits mit geringem Spiel in einem der Rollenkäfige 5 oder 6 (Fig. 4 bzw. 8) lose drehbar gelagert sind. Im Neuzustand des Festwalzwerkzeugs beträgt das Spiel zwischen der Festwalzrolle 4 und dem jeweiligen Rollenkäfig 5 oder 6 jeweils etwa 0,1 mm bis 0,5 mm, vorzugsweise 0,2 mm. Die Stirnseiten 8 einer inneren Ausnehmung 17 'der beiden Rollenkäfige 5 und 6 haben einen seitlichen Abstand voneinander und auch einen seitlichen Abstand zum Drehmittelpunkt 7 des Gehäuses 2; letzterer beträgt etwa 0,2 mm.11 shows a section along the line B1-B1. The deep rolling roller head 1 has an approximately rectangular, flat housing 2. The underside 3 of the housing 2 faces the crankshaft 21, of which FIG. 1 shows the section through any main bearing, the bearing journals of which are delimited laterally by radii or recesses 22. Deep rolling rollers 4 engage in these radii or recesses 22, which in turn are loosely rotatably mounted in one of the roller cages 5 or 6 (FIGS. 4 and 8) with little play. When the deep rolling tool is in new condition, the play between the deep rolling roller 4 and the respective roller cage 5 or 6 is in each case approximately 0.1 mm to 0.5 mm, preferably 0.2 mm. The end faces 8 of an inner recess 17 'of the two roller cages 5 and 6 have a lateral distance from one another and also a lateral distance from the center of rotation 7 of the housing 2; the latter is about 0.2 mm.
Auf ihren, einander zugewandten Stirnseiten 8 der inneren Ausnehmung 17 haben die Rollenkäfige 5 und 6 jeweils nutenförmige Ausnehmungen 9, in denen eine Festwalzrolle 4 auf zwei einander gegenüberliegenden Seiten am Umfang ihres Körpers drehbar geführt wird. Die Figuren 5 und 9 zeigen die beiden Ausnehmungen 9 auf den Stirnseiten 8 jeweils eines Rollenkäfigs 5 bzw. 6. Die in den Figuren 5 und 9 erkennbare Schräglage der beiden Ausnehmungen 9 entspricht zugleich der Schräglage der Festwalzrollen 4 im Festwalzrollenkopf 1.On their mutually facing end faces 8 of the inner recess 17, the roller cages 5 and 6 each have groove-shaped recesses 9, in which a deep-rolling roller 4 is rotatably guided on two opposite sides on the circumference of its body. FIGS. 5 and 9 show the two recesses 9 on the end faces 8 of a roller cage 5 and 6, respectively. The inclined position of the two recesses 9 that can be seen in FIGS. 5 and 9 also corresponds to the inclined position of the deep-rolling rollers 4 in the deep-rolling roller head 1.
Auf ihren der inneren Stirnseite 8 -gegenüber liegenden äußeren Stirnseiten 10 stützen sich die Rollenkäfige 5 und 6 auf entsprechenden Vorsprüngen 11 und 12 ab. Die VorSprünge 11 und 12 springen jeweils auf der Unterseite 3 des Gehäuses 2 hervor und geben zwischen einander eine Ausnehmung 13 frei, worin die jeweiligen Rollenkäfige 5 oder 6 mit ihren Festwalzrollen 4 aufgenommen sind. Die Rollenkäfige 5 oder 6 sind mit dem Gehäuse 2 beziehungsweise mit dessen Vorsprüngen 11 und 12 nicht verbunden. Sie sind in der Ausnehmung 13 zwischen den beiden Vorsprüngen "11 und 12 mit geringem Spiel gelagert und geführt, so dass sie von der Unterseite 3 her in die Ausnehmung 13 hineingeschoben werden können. Dabei stützen sich die Rollenkäfige 5 und 6 mit ihren rückwärtigen Stirnseiten 10 jeweils auf entsprechenden Flächen 14 der Vorsprünge 11 und 12 ab.The roller cages 5 are supported on their outer end faces 10 lying opposite the inner end face 8 and 6 on corresponding protrusions 11 and 12. The projections 11 and 12 each jump out on the underside 3 of the housing 2 and open a recess 13 between them, in which the respective roller cages 5 or 6 are accommodated with their deep-rolling rollers 4. The roller cages 5 or 6 are not connected to the housing 2 or its projections 11 and 12. They are mounted in the recess 13 between the two projections "11 and 12 with little play and is guided, so that they can be pushed into the recess 13 of the bottom 3 here. In this case, the roller cages 5 and 6, support with their rear end faces 10 in each case on corresponding surfaces 14 of the projections 11 and 12.
Beispielsweise zur Halterung des Rollenkäfigs 6 am Gehäuse 2 ist eine Lasche (nicht gezeigt) vorgesehen. Die Lasche besteht aus einem flachen Eisen von geringer Länge und Breite und ist jeweils über Schrauben (nicht gezeigt) mit dem jeweiligen Vorsprung 11 oder 12 des Gehäuses 2 lösbar verbunden. Mit ihrer freien Mitte greift die Lasche in eine Nut 18 ein, die auf der Unterseite 19 des Rollenkäfigs 6 ausgespart ist (Fig. 9 und 11) .For example, a bracket (not shown) is provided to hold the roller cage 6 on the housing 2. The tab consists of a flat iron of small length and width and is detachably connected to the respective projection 11 or 12 of the housing 2 by screws (not shown). With its free center, the tab engages in a groove 18 which is recessed on the underside 19 of the roller cage 6 (FIGS. 9 and 11).
Anstelle einer Lasche können auch Stifte 15 vorgesehen sein, welche die Halterung und Führung beispielsweise des Rollenkäfigs 5 an den Vorsprüngen 11 und 12 des Gehäuses 2 bewirken. Die Stifte 15 sind jeweils längs ihrer gemeinsamen Längsachse 16 in Gewindebohrungen 20 längsverschiebbar und feststellbar geführt, die jeweils die Längsmitte der Unterseite 3 des Gehäuses 2 durchziehen (Fig. 3) . Die Zapfen 15 weisen an ihren inneren, d.h. dem Festwalzrollenkäfig 5 zugewandten Enden, jeweils einen kleinen Zapfen 23 auf, mit welchem sie jeweils in eine Vertiefung 24 auf den äußeren Stirnseiten 10 des Festwalzrollenkäfigs 5 eingreifen, wie man das in der Fig. 1 deutlich sehen kann.Instead of a tab, pins 15 can also be provided, which effect the holding and guiding of the roller cage 5 on the projections 11 and 12 of the housing 2, for example. The pins 15 are each guided along their common longitudinal axis 16 in threaded bores 20 so as to be longitudinally displaceable and lockable, each of which runs through the longitudinal center of the bottom 3 of the housing 2 (FIG. 3). The pins 15 point to their inner, ie facing the deep rolling roller cage 5, each have a small pin 23 with which they each engage in a recess 24 on the outer end faces 10 of the deep rolling roller cage 5, as can be clearly seen in FIG. 1.
Während des Festwalzens der Einstiche 22 dreht sich die Kurbelwelle 21, vom Spindelantrieb der Eestwalzmaschine (nicht gezeigt) in Umdrehung versetzt, in Richtung des Pfeils 25 unter dem Festwalzrollenkopf 1 weg. During the deep rolling of the punctures 22, the crankshaft 21 rotates away from the spindle drive of the deep rolling machine (not shown) in the direction of arrow 25 under the deep rolling roller head 1.
