Description

Festwalzmaschine für Kurbelwellen Deep rolling machine for crankshafts
Die Erfindung betrifft eine Festwalzmaschine für Kurbelwellen mit mehreren Festwalzgeräten in scherenartiger Bauweise, die in Richtung der Drehachse der Kurbelwelle mit jeweils seitlichen Abständen nebeneinander an der Festwalzmaschine schwenkbar befestigt sind, indem einige Festwalzgeräte für das Festwalzen von Hauptlagerzapfen und andere Festwalzgeräte für das Festwalzen von Hublagerzapfen der Kurbelwelle vorgesehen sind und die Festwalzgeräte an den äußeren Enden von ihren beiden Scherenarmen jeweils einen Festwalzrollenkopf und einen Stützrollenkopf tragen, die miteinander ein Festwalzwerkzeug bilden, wobei das Festwalzwerkzeug entlang der Scherenarme von der zugehörigen Befestigung des Festwalzgeräts an der Festwalzmaschine einen im Verhältnis der Breite der Scherenarme zu deren Länge großen Abstand hat.The invention relates to a deep rolling machine for crankshafts with several deep rolling devices in scissors-like construction, which are pivotally mounted in the direction of the axis of rotation of the crankshaft with lateral distances side by side on the deep rolling machine by some deep rolling machines for deep rolling of main journals and other deep rolling machines for the deep rolling of journal bearing journals Crankshaft are provided and the deep rolling machines at the outer ends of their two scissor arms each carry a deep rolling head and a support roller head, which together form a deep rolling tool, the deep rolling tool along the scissor arms of the associated attachment of the deep rolling machine to the deep rolling a ratio of the width of the scissor arms has a large distance to the length.
Festwalzmaschinen der einschlägigen Art, mit Festwalzgeräten in scherenartiger Bauweise sind beispielsweise bekannt aus der EP 0 881 041 Bl. Eine Festwalzmaschine, welche Festwalzgeräte in scherenartiger Bauweise verwendet ist auch Gegenstand der älteren deutschen Patentanmeldung 10 2005 014 998.7-14 der Patentanmelderin .Deep-rolling machines of the pertinent type, with deep-rolling devices in scissor-like construction are known, for example, from EP 0 881 041 B1. A deep-rolling machine which uses deep-rolling machines of a scissor-like design is also the subject of the earlier German patent application 10 2005 014 998.7-14 of the patent applicant.
Die Festwalzgeräte in scherenartiger Bauweise zeichnen sich dadurch aus, dass das Festwalzwerkzeug entlang der Scherenarme von der zugehörigen Befestigung des Festwalzgeräts an der Festwalzmaschine einen im Verhältnis der Breite der Scherenarme zu deren Länge großen Abstand hat. Daraus ergibt sich, dass das Festwalzgerät in Richtung der Drehachse der Kurbelwelle, um welche sie sich in der Festwalzmaschine dreht, eine verhältnismäßig geringe Stabilität aufweist. Beim Vorhandensein von mehreren Festwalzgeräten, wie das an den modernen Festwalzmaschinen für Kurbelwellen der Fall ist, können sich infolgedessen beim Festwalzen der Kurbelwelle unerwünschte Bewegungen, wie beispielsweise Axialschwingungen, einstellen, welche sich auf alle Festwalzgeräte übertragen. Derartige Schwingungen führen infolgedessen zu einer Verschlechterung des Arbeitsergebnisses .The deep-rolling devices in scissors-like design are characterized by the fact that the deep rolling tool along the scissor arms of the associated attachment of the deep rolling machine on the deep rolling machine in the Ratio of the width of the scissor arms to their length has a large distance. It follows that the deep rolling device in the direction of the axis of rotation of the crankshaft, by which it rotates in the deep rolling machine, has a relatively low stability. As a result, in the presence of several deep rolling machines, as is the case on modern deep-rolling machines for crankshafts, undesired movements, such as axial oscillations, which are transmitted to all deep-rolling machines, can occur during deep rolling of the crankshaft. As a result, such vibrations lead to a deterioration of the work result.
Daraus ergibt sich die Aufgabe für die vorliegende Erfindung, eine Einrichtung an der Festwalzmaschine vorzusehen, welche die Festwalzgeräte längs der Drehachse der Kurbelwelle beim Festwalzen stabilisiert. Die Einrichtung soll möglichst einfach ausgestaltet sein und die Wirkungsweise der Festwalzgeräte nicht beeinträchtigen sondern im Gegenteil noch erhöhen.This results in the object for the present invention to provide a device on the deep rolling machine, which stabilizes the deep rolling devices along the axis of rotation of the crankshaft during deep rolling. The device should be as simple as possible and not affect the operation of the deep rolling machines but on the contrary increase.
Als Lösung der Aufgabe wurde gefunden, dass die Festwalzgeräte in der axialen Richtung stabilisiert werden können, wenn wenigstens eines der für das Festwalzen der Hauptlagerzapfen oder der Hublagerzapfen vorgesehenen Festwalzgeräte eine Einrichtung aufweist, die in der Arbeitsstellung des Festwalzgeräts an der Kurbelwelle angereift und das Festwalzgerät in Richtung der Drehachse der Kurbelwelle stabilisiert.As a solution to the problem has been found that the deep rolling machines can be stabilized in the axial direction, if at least one of the provided for the deep rolling of the main journals or Hublagerzapfen deep rolling equipment has a device that matured in the working position of the deep rolling mill on the crankshaft and the deep rolling machine in Direction of the axis of rotation of the crankshaft stabilized.
Im einfachsten Fall besteht eine derartige Einrichtung aus einer Axialführungsrolle, welche am Stützrollenkopf befestigt ist und beim geschlossenen Festwalzwerkzeug zwischen die zugehörigen Ölbunde eines Lagerzapfens der Kurbelwelle eingereift. Eine Axialführungsrolle, die am Stützrollenkopf befestigt ist, ist beispielsweise aus der EP 1 112 146 Bl bekannt. Diese Axialführungsrolle ist dazu vorgesehen, während des Schließens des Festwalzwerkzeugs das Anstoßen entweder der Festwalzrollen oder der Stützrollen an den Ölbunden der Kurbelwelle zu vermeiden.In the simplest case, such a device consists of an axial guide roller, which is attached to the support roller head and the closed deep rolling tool between the associated oil bundles of a journal of the crankshaft. An axial guide roller, which is attached to the support roller head, is known for example from EP 1 112 146 Bl. This Axialführungsrolle is intended to avoid during the closing of the deep rolling tool, the abutment of either the deep rolling rollers or the support rollers on the oil collars of the crankshaft.
Eine andere Axialführungsrolle, welche amAnother Axialführungsrolle, which at
Festwalzrollenkopf angebracht ist, ist aber auch aus dem deutschen Patent DE 103 61 738 B3 bekannt. Der bekannten Einrichtung liegt die Aufgabe zugrunde eine Führungseinrichtung zu schaffen die dazu geeignet ist vom Festwalzwerkzeug ausgehende oder am Festwalzwerkzeug entstehende Kräfte in axialer Richtung aufzufangen. Der Vorteil der Wirkungsweise der bekannten Einrichtung besteht darin, dass eine auf dem Festwalzrollenkopf festangeordnete Axialführungsrolle, welche eine axiale Bewegung des Festwalzgeräts in der Längsrichtung der Drehachse der Kurbelwelle begrenzt, Kräfte, die in derselben Richtung wirken, in den Ölbund der Kurbelwelle einleitet. Im Zusammenhang mit der bekannten Einrichtung war aber eher daran gedacht worden, unterschiedlich große Festwalzkräfte, wie sie mitunter an den Festwalzrollen entstehen können, in die Kurbelwelle einzuleiten (vgl. Figuren 6 und 7) . Hingegen stand der Gedanke, die Gesamtheit der Festwalzgeräte in der axialen Richtung zu stabilisieren und gegebenenfalls Schwingungen zu unterdrücken, bei der bekannten Einrichtung noch nicht zur Diskussion. Insbesondere war auch nicht erkannt worden, dass eine Axialführungsrolle, die am Stützrollenkopf angebracht ist, wie sie aus der bereits genannten EP 1 112 146 bekannt ist, eine stabilisierende Wirkung auf die übrigen Festwalzgeräte einer Festwalzmaschine ausüben kann.Hard roller head is attached, but is also known from German Patent DE 103 61 738 B3. The known device has the object to provide a guide device which is suitable from the deep rolling tool outgoing or on the deep rolling tool resulting forces to absorb in the axial direction. The advantage of the mode of operation of the known device is that an axial guide roller fixedly arranged on the deep-rolling roller head, which limits an axial movement of the deep-rolling device in the longitudinal direction of the axis of rotation of the crankshaft, introduces forces acting in the same direction into the crankshaft of the crankshaft. In connection with the known device but was rather thought to different sized deep rolling forces, as they may sometimes arise on the fixed rollers, to be introduced into the crankshaft (see Figures 6 and 7). By contrast, the idea of stabilizing the entirety of deep-rolling devices in the axial direction and optionally suppressing vibrations was not yet discussed in the known device. In particular, it had not been recognized that an axial guide roller, which is attached to the support roller head, as is known from the already mentioned EP 1 112 146, a stabilizing Can exert effect on the remaining deep rolling machines of a deep-rolling machine.
Aus der EP 1 469 972 Bl ist eine Axialführungseinrichtung bekannt, die als prismatischer Gleitkörper ausgebildet ist. Auch diese bekannte Einrichtung ist am Stützrollenkopf befestigt und greift bei geschlossenem Festwalzwerkzeug zwischen zugehörigen Ölbunden eines Lagerzapfens einer Kurbelwelle ein. Im Zusammenhang mit der bekannten Einrichtung ist es auch bekannt, aufgrund der scherenartigen Bauweise des Festwalzgeräts, dass die Axialführung zugleich auch die Führung des Festwalzrollenkopfes in axialer Richtung der Kurbelwelle übernimmt .From EP 1 469 972 Bl an axial guide device is known, which is designed as a prismatic sliding body. This known device is attached to the support roller head and engages with closed deep rolling tool between associated oil collars of a journal of a crankshaft. In connection with the known device, it is also known, due to the scissor-type design of the deep rolling device, that the axial guidance at the same time takes over the leadership of the deep rolling roller head in the axial direction of the crankshaft.
Eine weitergehende Ausführungsform der vorliegenden Erfindung sieht sodann vor, Einrichtungen zur Stabilisierung der Festwalzgeräte entlang der Scherenarme der Festwalzgeräte anzubringen. Bevorzugt ist ein Abschnitt zwischen einem äußeren Ende eines Scherenarms, wo entweder der Festwalzrollenkopf oder der Stützrollenkopf befestigt sind, und dem Drehpunkt der Schere, die von den Scherenarmen gebildet wird, anzuordnen und von dort aus an der Kurbelwelle angreifen zu lassen. Bei solchen Einrichtungen kann es sich bevorzugt um Distanzstücke oder Abstandshalter handeln, welche den gegenseitigen Abstand der Festwalzwerkzeuge einerseits und den Eingriff in die Kurbelwelle andererseits gewährleisten. Eine solche Lösung bietet sich vor allem dann an, wenn es sich um das Bearbeiten von komplizierten Kurbelwellen, beispielsweise Split-Pin- Kurbelwellen handelt, wo aus Platzgründen eine Axialführungsrolle am Festwalzrollenkopf oder am Stützrollenkopf nicht angebracht werden kann. Nachfolgend wird die Erfindung an einem Ausführungsbeispiel näher beschrieben. Es zeigt:A further embodiment of the present invention then provides to install means for stabilizing the deep rolling devices along the scissor arms of the deep rolling equipment. Preferably, a portion between an outer end of a scissor arm, where either the deep rolling roller head or the support roller head are fixed, and the pivot point of the scissors, which is formed by the scissor arms, to arrange and attack from there on the crankshaft. In such devices may preferably be spacers or spacers, which ensure the mutual distance of the deep rolling tools on the one hand and the engagement in the crankshaft on the other. Such a solution is particularly useful when it comes to the processing of complicated crankshafts, such as split-pin crankshafts, where for reasons of space an axial guide roller on the deep rolling head or on the support roller head can not be attached. The invention will be described in more detail with reference to an exemplary embodiment. It shows:
- die Fig. 1 eine Festwalzmaschine in perspektivischer Ansicht und- Fig. 1 is a deep rolling machine in perspective view and
- die Fig. 2 ein Festwalzwerkzeug in der Seitenansicht und- Fig. 2 is a deep rolling tool in the side view and
- die Fig. 3 einen Schnitt durch das Festwalzwerkzeug der Fig. 2 entlang der Linie III-III.3 shows a section through the deep rolling tool of FIG. 2 along the line III-III.
An einem Querbalken 1 der Festwalzmaschine 2 sind mehrere Festwalzgeräte 3 nebeneinander angeordnet. Die Festwalzgeräte 3 sind in scherenartiger Bauweise ausgeführt und entlang der Drehachse 4 einer in der Festwalzmaschine 2 eingespannten Kurbelwelle 5 mit gegenseitigem Abstand 6 am Querbalken 1 befestigt. Die Festwalzgeräte 3 haben jeweils eine Breite 7, welche im Verhältnis zu ihrer Länge gering ist. Daraus ergibt sich, dass die Festwalzgeräte 3 in Richtung der Drehachse 4 besonders biegeweich sind. Aus der Biegeweichheit wiederum resultiert die Möglichkeit, dass sich beim Festwalzen der Kurbelwelle 5 in der Festwalzmaschine 2 Schwingungen einstellen können, welche in die axiale Richtung 4 gerichtet sind und alle Festwalzgeräte 3 erfassen können.On a crossbar 1 of the deep rolling machine 2 more deep rolling 3 are arranged side by side. The deep rolling devices 3 are designed in a scissor-like construction and attached along the axis of rotation 4 of a clamped in the deep rolling machine 2 crankshaft 5 with mutual distance 6 on the crossbar 1. The deep rolling devices 3 each have a width 7 which is small in relation to their length. It follows that the deep rolling 3 in the direction of the axis of rotation 4 are particularly flexible. The bending softness in turn results in the possibility that during the deep rolling of the crankshaft 5 in the deep rolling machine 2 oscillations can occur, which are directed in the axial direction 4 and can detect all deep rolling devices 3.
Zum Vermeiden von solchen Schwingungen ist eineTo avoid such vibrations is a
Axialführungsrolle 8 vorgesehen, die am Stützrollenkopf 9 des Festwalzwerkzeugs 10 drehbar gelagert ist. Bei geschlossenem Festwalzwerkzeug 10, welches aus demAxial guide roller 8 is provided, which is rotatably mounted on the support roller head 9 of the deep rolling tool 10. With closed deep rolling tool 10, which from the
Festwalzrollenkopf 11 und dem Stützrollenkopf 9 besteht, wie sie in der Fig. 2 gezeigt sind, greift dieFestrolling roller head 11 and the support roller head 9, as shown in FIG. 2, engages the
Axialführungsrolle 8 zwischen die zugehörigen Ölbunde 12 und 13 eines Lagerzapfens 14 der Kurbelwelle 5 ein. Mit diesem Eingriff stabilisiert die Axialführungsrolle 8 das zugehörige Festwalzgerät 3 in der axialen Richtung 4 und leitet Kräfte, welche am Festwalzgerät 3 zwischen der Befestigung am Querbalken 1 und dem Festwalzwerkzeug 10 am äußeren Ende der Scherenarme des Festwalzgeräts 3 entstehen können, in die Kurbelwelle 5 ein und stabilisiert auf diese Weise das zugehörige Festwalzgerät 3. Solche Kräfte können beispielsweise in Folge von Schwingungen entstehen, die sich an einem der Festwalzgeräte der Festwalzmaschine 2 aufgrund unterschiedlicher Kräfte in der axialen Richtung 4 einstellen .Axialführungsrolle 8 between the associated oil bundles 12 and 13 of a journal 14 of the crankshaft 5 a. With this engagement stabilizes the Axialführungsrolle 8 the associated deep rolling unit 3 in the axial direction 4 and directs forces that can arise on the deep rolling 3 between the attachment to the crossbar 1 and the deep rolling tool 10 at the outer end of the scissor arms of deep rolling 3, in the crankshaft 5 and Such forces can arise, for example, as a result of vibrations that occur on one of the deep rolling machines of the deep rolling machine 2 due to different forces in the axial direction 4.
Es genügt bereits, wenn einzelne Festwalzgeräte 3 einer Festwalzmaschine 2 in Richtung der Drehachse 4 stabilisiert werden. Das kann beispielsweise geschehen durch eine oder mehrere Festwalzwerkzeuge 10, welche an den Hublagerzapfen 14 der Kurbelwelle 5 angreifen oder eine oder mehrere Festwalzwerkzeuge 10, welche an den Hublagerzapfen der Kurbelwelle 5 angreifen. Generell aber ist man dazu übergegangen, sämtliche Festwalzgeräte 3 einer Festwalzmaschine 2 mit den Einrichtungen zu versehen, die die Festwalzgeräte 3 in der axialen Richtung 4 stabilisieren.It is already sufficient if individual deep rolling machines 3 of a deep rolling machine 2 are stabilized in the direction of the axis of rotation 4. This can be done, for example, by one or more deep-rolling tools 10 which engage the crankpins 14 of the crankshaft 5 or one or more deep-rolling tools 10 which engage the crankpins of the crankshaft 5. In general, however, it has gone over to provide all deep rolling 3 of a deep rolling machine 2 with the facilities that stabilize the deep rolling 3 in the axial direction 4.
Nicht zeichnerisch dargestellt in der vorliegenden Anmeldung ist ein weiteres Ausführungsbeispiel, wonach im gegenseitigen Abstand 6 zwischen einzelnen Festwalzgeräten 3 Einrichtungen zur Stabilisierung angebracht werden können. Dabei kann es sich beispielsweise um Distanzstücke oder Abstandshalter handeln, die von einem Punkt am Scherenarm eines Festwalzgeräts 3 ausgehend in einen Lagerzapfen 14 einer Kurbelwelle 5 eingreifen. Bevorzugte Orte der Anbringung von derartigen Stabilisatoren sind beispielsweise Gelenkpunkte an den Scherenarmen der Festwalzgeräte 3. Not illustrated in the present application is another embodiment, according to which 3 devices for stabilization can be mounted at a mutual distance 6 between individual deep rolling equipment. These may be, for example, spacers or spacers which, starting from a point on the scissor arm of a deep rolling machine 3, engage in a bearing journal 14 of a crankshaft 5. Preferred locations of attachment of such stabilizers are, for example, hinge points on the scissor arms of the deep rolling devices 3.
