Der Fertigungsablauf zur Bearbeitung eines Radialrillenkugeilagerinnenringes gestaltet sich wie folgtiFig. 1 bis 5):The manufacturing process for machining a radial groove ball bearing inner ring is as follows. 1 to 5):
Im umformenden Bearbeitungskomplex, der mit einer Profilwalzmaschine realisiert wird, wird ein Rohr 2 zunächst durch Axialprofilrohrwalzen und Walzeinstechen mittels kombinierten Profil-Einstechwalzwerkzeuges 1 entsprechend det AuCenkontur des Kugellagerinnenringes profiliert (Fig. 1). Nach Vorschub des Rohres 2 und dessen Spannen am bereits durch Walzen bearbeiteten Rohrende erfolgt das Absprengen des Ringes 5 vom Rohr 2 mittels Trennwalzwerkzeug 3. Dieses weist einen Spitzenwinkel zwischen 45°...90° auf und greift in dem durch Walzeinstechen vorprofilierten Einstich an (Fig.2).In the forming machining complex, which is realized with a profile rolling machine, a tube 2 is first profiled by Axialprofilrohrwalzen and roll grooving by means of combined profile grooving tool 1 according to AuCenkontur the ball bearing inner ring (Fig. 1). After advancement of the tube 2 and its clamping on the already machined by rolling tube end, the ring 5 is broken off the tube 2 by means of a separating roller 3. This has a point angle between 45 ° ... 90 ° and engages in the pre-profiled by roll grooving puncture ( Figure 2).
Axialprofilrohrwalzen, Walzeinstechen sowie Absprengen werden gleichzeitig in der Spindellage I durchgeführt, wobei der Fing 5 sich in einem Spannfutter 4 befindet. Mit dem Absprengen des Ringes 5 vom Rohr 2 wird dieser vollständig in den spanenden Bearbeitungskomplex überführt, der im vorliegenden Fall mit einem Vierspindel-Frontdrehautomaten realisiert wird. Hier wird der Ring 5 durch Drehen in den Spindellagen Il bis IV einschließlich Wenden des Werkstückes wie folgt fertigbearbeitet (Fig.3 bis 5):Axialprofilrohrwalzen, roller grooving and blasting are performed simultaneously in the spindle position I, wherein the finger 5 is located in a chuck 4. With the blowing off of the ring 5 from the pipe 2 this is completely transferred to the machining complex, which is realized in the present case with a four-spindle automatic lathe. Here, the ring 5 is finished by turning in the spindle positions II to IV including turning of the workpiece as follows (Fig.3 to 5):
Nach der Arbeitsoperation Innen-Ausdrehen (Vordrehen) der Bohrung mittels Innen-Ausdrehwerkzeuges 6 sowie Plandrehen der ersten Ringstirnseite mittels Plandr^hwerkzeuges 7 in der Spindellage Il (Fig. 3) folgt die Arbeitsoperation Innen-Ausdrehen (Fertigdrehen) der Bohrung mittels Innenausdrehwerkzeuges 6 sowie Innen-Anfasen der ersten Ringstirnseite mittels Profildrehwerkzeuges 8 in Spindellage III (Fig.4). Schließlich folgt die Arbeitsoperation Plandrehen der zweiten Ringstirnseite mittels Plandrehwerkzeuges 7 sowie Innen-Anfasen der zweiten Ringstirnseite mittels Profildrehwerkzeuges 8 In der Spindellage IV (Fig.. 5).After the work operation inside-turning (pre-turning) the bore by means of internal boring tool 6 and facing the first ring face by means of Plandr ^ hwerkzeuges 7 in the spindle position Il (Figure 3), the work operation inside-turning (finish turning) of the bore by Innenausdrehwerkzeuges 6 and Internal chamfering of the first annular end face by means of profile turning tool 8 in spindle position III (Figure 4). Finally, the working operation facing the second annular face side by means of facing tool 7 and internal chamfering of the second annular face side by means of profile turning tool 8 in the spindle position IV (Fig .. 5).
Der Fertigungsablauf zur Bearbeitung eines Kegelrollenlagerinnenringes gestaltet sich wie folgt (Fig. 5 bis 10):The manufacturing process for machining a tapered roller bearing inner ring is as follows (FIGS. 5 to 10):
Im umformenden Bearbeitungskomplex wird das Rohr 2 zunächst durch Axialprofilrohrwalzen mittels Profilwalzwerkzeuges 13 bei Verwendung eines Domes 9 profiliert (Fig. 6). Anschließend erfolgt das Herausziehen des Domes 9 bei gleichzeitigem Vorschieben des Rohres 2. Nach dessen Aufnahme im Spannfutter 4 erfolgt die Bearbeitung der Außenkontur durch Außenkonturdrehen mittels Profildrehwerkzeuges 11 sowie das Abstechen des Ringes 5 mittels Abstechdrehwerkzeuges 10In the forming processing complex, the tube 2 is first profiled by Axialprofilrohrwalzen by means of profile rolling tool 13 when using a dome 9 (Fig. 6). After its removal in the chuck 4, the machining of the outer contour by external contour turning by means of profiled turning tool 11 and the tapping of the ring 5 by means of Abstechdrehwerkzeuges 10 takes place
Die weitere spanende Fertigbearbeitung wird analog zum Radialrillenkugellagerinnenring durchgeführt (Fig.8 bis 10).The further machining finishing is carried out analogously to the radial groove ball bearing inner ring (Figure 8 to 10).
In Spindellage Il erfolgen das Innen-Ausdrehen (Vordrehen) der Bohrung mittels Innen-Ausdrehwerkzeuges 6 sowie das Plandrehen der ersten Ringstirnseite mittels Plandrehwerkzeuges 7 zuzüglich des Freistechens des großen Bordes mittels Profildrehwerkzeuges 12 (Fig. 8). Daran schließen sich in Spindellage III die Arbeitsoperationen Innen-Ausdrehen (Fertigdrehen) der Bohrung mittels Innen-Ausdrehwerkzeuges 6 sowie Innen-Anfasen der ersten Ringstirnseite mittels Profildrehwerkzeuges 8 an (Fig. 9). Nach Umspannen des Werkstückes von außen auf innen erfolgen die abschließenden Arbeitsoperationen Plandrehen der zweiter, rtingstirnueite mittels Plandrehwerkzeuges 7 sowie Innen-Anfasen der zweiten Ringstirnseite mittels Profildreh> /erkzeuges 3 in Spindellage IV (Fig. 10).In spindle position II, the inner boring (pre-turning) of the bore by means of internal boring tool 6 and the facing of the first annular end side by means of facing tool 7 plus the free edge of the large board done by profile turning tool 12 (Fig. 8). This is followed in Spindellage III, the work operations inside-turning (finish turning) of the bore by means of internal Ausdrehwerkzeuges 6 and inner chamfering the first annular face by means of profile turning tool 8 (Fig. 9). After the workpiece has been clamped from the outside to the inside, the final working operations face turning of the second, rtingstirnueite means of facing tool 7 and internal chamfering of the second annular face by means Profertreh> / erkzeuges 3 in spindle position IV (Fig. 10).
Während beim Axialprofilrohrwalzen und/oder Walzeinstechen ohne Dorn die Spindellage I lediglich zum Spannen wahlweise innen oder außen des bereits bearbeiteten Rohrendes genutzt wird, kann insbesondere beim Walzen mit Dorn, vorzugsweise bei der Bearbeitung von Kegelrollenlagerinnenringen, nach dessen Zurückfahren in Ausgangsstellung in dieser Spindellage yternativ zum Walzeinstechen bzw. Absprengen ein Abstechen des Ringes vom Rohr mittels Abstechdrehwerkzeuges 10 erfolgen. Insbesondere bei Kegelrollenlagerinnenringen, wo sich teilweise eine spanende Fertig- bzw. Nachbearbeitung der Außenkontur des Ringes erforderlich macht, steht hierfür gleichfalls Spindellage I zur Verfugung (Fig. 7).While in the Axialprofilrohrwalzen and / or roll grooving without mandrel, the spindle position I is used only for clamping either inside or outside of the already machined pipe end, especially when rolling with mandrel, preferably in the processing of tapered roller bearing inner rings, after its return to the starting position in this spindle position alternately to Roller grooving or breaking off a cut off of the ring from the pipe by means of parting turning tool 10. In particular with tapered roller bearing inner rings, where partial machining or finishing of the outer contour of the ring is required, spindle position I is also available for this purpose (FIG. 7).
