Description

Die Erfindung betrifft eine Rollenhaltereinheit für ein Presswerkzeug nach dem Oberbegriff des unabhängigen Patentanspruches. Eine solche Rollenhaltereinheit ist der US-B-6240626 zu entnehmen.The invention relates to a roller holder unit for a pressing tool according to the preamble of the independent claim. Such a roller holder unit is the US-B-6240626 refer to.

Aus der DE-196'31'019 ist ein Pressgerät bekannt, welches eine Presszange zum Verbinden eines Rohres mit einem Pressfitting umfasst. Die Presszange umfasst zwei Schwenkarme, welche mittels je einem Bolzen schwenkbar zwischen zwei gleichen T-förmigen Trägerplatten angelenkt sind. Eine Kolben-Zylindereinheit ist mit einem Rollenhalter wirkverbunden, welcher zwei Rollen umfasst. Die Schwenkarme sind an einem Ende mit einer Abrollfläche für die Anlage am Presszylinder des Pressgerätes versehen. Am gegenüberliegenden Ende sind sie als Klemmbacken mit zueinander gerichteten Pressflächen ausgestaltet. Die Anlenkungen für die Bolzen befinden sich an den Trägerplatten im Abstand. Im Bereich des freien Endes der T-förmigen Trägerplatten befindet sich eine Aufnahme eines Verbindungsbolzens zur Verbindung mit dem Pressgerät. Beim Einsatz dieses Gerätes wird nun die Presszange nach hinten zum Pressgerät gezogen. Dabei gleiten die Schwenkarme mit ihren Abrollflächen am Pressgerät entlang nach hinten. Die Zugkraft wird über den Verbindungsbolzen auf die T-förmigen Trägerplatten übertragen. Dadurch schwenken die Schwenkarme um die Lagerbolzen, und die Pressbacken werden gegeneinander bewegt und zusammengedrückt.From DE-196'31'019 a pressing device is known, which comprises a pressing tongs for connecting a pipe with a press fitting. The pressing tongs comprise two pivoting arms, which are articulated by means of one pin each pivotally between two identical T-shaped support plates. A piston-cylinder unit is operatively connected to a roller holder comprising two rollers. The pivot arms are provided at one end with a rolling surface for the system on the pressing cylinder of the pressing device. At the opposite end, they are designed as jaws with mutually facing pressing surfaces. The linkages for the bolts are located on the carrier plates at a distance. In the region of the free end of the T-shaped support plates is a receptacle of a connecting pin for connection to the pressing device. When using this device, the pressing tongs are now pulled back to the pressing device. The swivel arms slide with their rolling surfaces along the pressing device to the rear. The tensile force is transmitted via the connecting bolt on the T-shaped support plates. As a result, the pivot arms pivot about the bearing pins, and the pressing jaws are moved against each other and compressed.

Aus der EP-1'103'349 ist ein elektrisch betriebenes Presswerkzeug bekannt, welches mittels einer elektrisch betriebenen Hydraulikpumpe eine hydraulische Kolben-Zylindereinheit betätigt. Diese ist wirkverbunden mit einem Rollenhalter, welcher zwei Rollen umfasst. Die Klemmbacken sind mittels einer T-förmigen Aufhängung über einen Haltebolzen mit einer gabelförmigen Aufnahme verbunden. Die gabelförmige Aufnahme ist Teil der Kolben-Zylindereinheit. Die Rollen am Rollenhalter rollen auf den Klemmbacken einer Klemmzange ab, sobald die Klemmzange durch die Kolben-Zylindereinheit rückwärts gezogen und damit die Klemmung vollzogen wird. Dabei wird die Klemmzange zusammengepresst, indem die Klemmbacken hinten durch die Rollen auseinandergedrückt werden. Bei dieser Ausführung weist der Rollenhalter die Gestalt eines Joches auf, welches mit der Kolbenstange fest verbunden ist. Rollenhalter, Rollen und Rollenlagerung müssen sehr massiv ausgeführt sein, da doch die ganze Presskraft und die Betätigungskraft der Kolben-Zylindereinheit beim Abrollen der Rollen an den Klemmbacken von den Rollen über deren Lagerung aufgenommen und auf den Rollenhalter übertragen werden muss. Diese Ausführung des Rollenhalters bedingt eine entsprechende Baugrösse und Dimensionierung der Halteplatten und der Rollen, Rollenlager und Lagerstifte. Sie ist dementsprechend schwer und aufwendig in der Herstellung.From EP-1'103'349 an electrically operated pressing tool is known, which actuates a hydraulic piston-cylinder unit by means of an electrically operated hydraulic pump. This is operatively connected to a roll holder, which comprises two rollers. The jaws are connected by a T-shaped suspension via a retaining bolt with a fork-shaped receptacle. The fork-shaped receptacle is part of the piston-cylinder unit. The rollers on the roll holder roll on the jaws of a pair of pliers as soon as the clamping pliers pulled backwards by the piston-cylinder unit and thus the clamping is completed. The clamping forceps are pressed together by pushing apart the jaws at the back through the rollers. In this embodiment, the roll holder in the form of a yoke, which is firmly connected to the piston rod. Roller holder, rollers and roller bearings must be made very solid, since the whole pressing force and the operating force of the piston-cylinder unit must be taken when rolling the rollers on the jaws of the roles of their storage and transferred to the roll holder. This embodiment of the roller holder requires a corresponding size and dimensioning of the holding plates and the rollers, roller bearings and bearing pins. It is therefore difficult and expensive to manufacture.

Ein Presswerkzeug nach dem Stand der Technik ist in Figur 1 dargestellt. Es umfasst eine Antriebseinheit 70, eine Kolben-Zylindereinheit 5 mit einer gabelförmigen Aufnahme 55 und die eigentliche Klemmzange 60. Die Klemmzange 60 ist an einer T-förmigen Halterung befestigt, welche mit einem Haltebolzen 54 und .einer Haltebolzenaufnahme 61 mit der gabelförmigen Aufnahme 55 verbunden ist. In der gabelförmigen Aufnahme 55 befindet sich ein Rollenhalter mit zwei Rollen. Die gabelförmige Aufnahme 55 ist Teil der Kolben-Zylindereinheit 5. Die Rollen rollen auf den Klemmbacken 62 einer Klemmzange 60 ab, sobald die Kolbenstange nach vorne gestossen wird.. Dabei wird die Klemmzange 60 zusammengepresst, indem die Klemmbacken 62 hinten durch die Rollen auseinandergedrückt werden. Die Klemmung wird vollzogen.A pressing tool according to the prior art is shown in FIG. It comprises a drive unit 70, a piston-cylinder unit 5 with a fork-shaped receptacle 55 and the actual clamping tongs 60. The clamping tongs 60 is fastened to a T-shaped holder, which is connected to a retaining bolt 54 and .a retaining pin receptacle 61 to the fork-shaped receptacle 55 is. In the fork-shaped receptacle 55 There is a roll holder with two rollers. The fork-shaped receptacle 55 is part of the piston-cylinder unit 5. The rollers roll on the jaws 62 of a clamping pliers 60 as soon as the piston rod is pushed forward .. The clamping forceps 60 is compressed by the clamping jaws 62 are pushed apart by the rear rollers , The clamping is completed.

Die Verbindung von Antriebseinheit 70 und Klemmzange 60 wird durch die Kolben-Zylindereinheit 5 gebildet. Sie besteht nach Figur 2 aus dem Zylinderkopf 51 mit einer Durchbohrung zur Aufnahme eines Haltebolzens 54 für die Befestigung der Klemmzange 60. Im Zylinderkopf befindet sich eine Druckfeder 57, welche eine Kolbenstange 52 in eine Ruheposition nach vorne stösst. In der gabelförmigen Aufnahme 55 ist eine der Rollen 2 teilweise sichtbar. Beim Betätigen des Presswerkzeuges wird die Kolbenstange 52 nach vorne gestossen. Der Zylinderkopf 51 bleibt ortsfest, wodurch die Rollen 2 innerhalb der gabelförmigen Aufnahme 55 relativ nach vorne bewegen. Die Pressbacken 62 ragen etwas in die gabelförmige Aufnahme 55 hinein und liegen mit ihren Abrollflanken 63 aussenseitig an den Rollen 2 an. Die Rollen 2 laufen somit an den Pressbacken 62 entlang der Abrollflanken 63 und drücken diese nach aussen. Die Pressung wird in der Klemmzange 60 ausgeführt.The connection of drive unit 70 and clamping tongs 60 is formed by the piston-cylinder unit 5. It consists of Figure 2 from the cylinder head 51 with a through hole for receiving a retaining bolt 54 for the attachment of the clamping tongs 60. In the cylinder head is a compression spring 57, which pushes a piston rod 52 in a rest position forward. In the fork-shaped receptacle 55, one of the rollers 2 is partially visible. When pressing the pressing tool, the piston rod 52 is pushed forward. The cylinder head 51 remains stationary, whereby the rollers 2 within the fork-shaped receptacle 55 move relatively forward. The pressing jaws 62 protrude somewhat into the fork-shaped receptacle 55 and, with their rolling flanks 63, bear against the rollers 2 on the outside. The rollers 2 thus run on the pressing jaws 62 along the rolling edges 63 and push them outwards. The pressing is carried out in the clamping tongs 60.

Mehr Details der Kolben-Zylindereinheit 5 sind aus Figur 3, im Schnitt dargestellt, im Zusammenhang mit der Rollenhaltereinheit ersichtlich. Die Kolbenstange 52 ragt einseitig in den Zylinderkopf 51. Sie ist mittels einer Druckfeder 57 vorgespannt. Die Druckfeder 57 umfasst die Kolbenstange 52 und ist am einen Ende an einer Federdruckscheibe 53 und am anderen Ende an einem Dichtungshaltering 50 im Anschlag. Die Federdruckscheibe 53 ist mit einer Schraube an der Kolbenstange 52 befestigt. Zwischen Dichtungshaltering 50 und Zylinderkopf 51 ist ein Abstreifring 59 angeordnet, welcher von der Kolbenstange 52 durchstossen ist. Am kopfseitigen Ende der Kolbenstange 52 ist die Rollenhaltereinheit befestigt. Sie ragt vom Zylinderkopf 51 in den Bereich der gabelförmigen Ausnahme 55 und zwar so, dass zwei Rollen 2 sich teilweise in der Gabelöffnung befinden. Ein Lagerbock 1 der Rollenhaltereinheit ist mittels einem Spannstift 58 an der Kolbenstange 52 fixiert. Wenn nun beim Betätigen des Presswerkzeuges die Kolbenstange 52 nach vorne geschoben wird, wobei der Zylinderkopf 51 und die Klemmzange 60 ortsfest bleiben, so wird die Rollenhaltereinheit innerhalb der gabelförmigen Aufnahme 55 gegen den Haltebolzen 54 und damit gegen die Klemmbacken 62 bewegt. Die Rollen 2 rollen somit den Abrollflanken 63 der Klemmbacken 62 entlang und drücken diese auseinander. Sobald die Pressung fertig erfolgt ist, wird die Kolbenstange 52 durch die Druckfeder 57 in die Ruheposition zurück bewegt. Damit gelangt auch die Rollenhaltereinheit wieder in die Ruheposition knapp ausserhalb dem Zylinderkopf 51.More details of the piston-cylinder unit 5 are shown in Figure 3, shown in section, in connection with the roller holder unit. The piston rod 52 projects on one side into the cylinder head 51. It is biased by a compression spring 57. The compression spring 57 includes the piston rod 52 and is at one end to a spring washer 53 and at the other end to a Seal retaining ring 50 in the stop. The spring pressure washer 53 is fastened to the piston rod 52 with a screw. Between seal retaining ring 50 and cylinder head 51, a scraper ring 59 is arranged, which is pierced by the piston rod 52. At the head end of the piston rod 52, the roller holder unit is attached. It protrudes from the cylinder head 51 in the region of the fork-shaped exception 55 in such a way that two rollers 2 are partially in the fork opening. A bearing block 1 of the roller holder unit is fixed by means of a clamping pin 58 on the piston rod 52. If now the piston rod 52 is pushed forward during actuation of the pressing tool, wherein the cylinder head 51 and the clamping tongs 60 remain stationary, the roller holder unit is moved within the fork-shaped receptacle 55 against the retaining pin 54 and thus against the jaws 62. The rollers 2 thus roll along the rolling edges 63 of the clamping jaws 62 and push them apart. Once the compression is done, the piston rod 52 is moved by the compression spring 57 back to the rest position. Thus, the roller holder unit returns to the rest position just outside the cylinder head 51st

Die Rollenhaltereinheit ist in Figur 4 in Ansicht gezeigt. Sie besteht aus einem Lagerbock 1, welcher einer zylindrischen Ausnehmung im Zylinderkopf 51, an dessen Stirn-Aussenseite entspricht. Senkrecht auf dem Lagerbock 1 ist mindestens ein, vorteilhafterweise aber zwei parallele Haltebleche 3 vorhanden. Sie sind mittels Schrauben 4 am Lagerbock 1 befestigt. Am Halteblech 3 respektive zwischen den beiden Halteblechen 3 sind zwei Rollen 2 voneinander beabstandet vorhanden. Die Rollen 2 sind so angeordnet, dass sie einander auf einer Geraden an ihrem Umfang berühren. Sie stützen sich also gegenseitig und rollen aufeinander ab. Mit Sicherungsstiften 21 sind sie gegen Herausfallen gesichert. Da die Sicherungsstifte 21 keine Lagerkräfte aufnehmen müssen sind sie schwach dimensioniert und benötigen an und für sich keine extra Lagerung für die Rollen 2 auf den Sicherungsstiften 21. Es ist sogar eine Ausführung ohne Durchbohrungen der Rollen 2 machbar. Die geometrische Anordnung und Auslegung der Klemmbacken kann ein Herausfallen der Rollen 2 verhindern. Die Sicherungsfunktion bei Zulassung von Rotationsbewegung der Rollen 2 ist auch gewährleistet, wenn der Rolleninnendurchmesser um einiges grösser ist als der Durchmesser der Sicherungsstifte 21 und somit viel Spiel vorhanden ist, genügen geeignete Oberflächen am Sicherungsstift 21 und an den Durchbohrungen der Rollen 2. Es können beispielsweise Stahlrollen mit Sicherungsstiften 21 aus Bronze verwendet werden, was eine dauernde Selbstschmierung hier garantiert. Entscheidend neu ist die Lagerung der Rollen 2 in der Rollenhaltereinheit. Die Rollen 2 stützen sich einerseits, wie beschrieben, gegeneinander ab und andererseits gegen geeignete Gleitlagerflächen 11, 12 am Lagerbock 1. Die Hauptbelastung der Rollen 2 beim Betätigen des Presswerkzeuges wird einerseits durch das Auseinanderdrücken der Abrollflanken 63 der Klemmbacken 62 erzeugt. Die Richtung dieser Belastung erfolgt über die Rollenoberfläche in einer Geraden durch das Zentrum der Rollen 2 auf die jeweils andere Rolle. Die Rollen 2 stützen sich also gegenseitig aufeinander ab. Das bedeutet, diese Belastung muss von keiner Lagerung und somit auch nicht von den Sicherungsstiften 21 und den Halteblechen 3 aufgenommen und übertragen werden. Eine zweite Art von Belastung der Rollen geschieht durch die Relativbewegung der Kolbenstange 52 und damit des Lagerbockes 1. Diese Belastung geschieht immer senkrecht zum Lagerbock 1. Zu diesem Zweck ist der Lagerbock 1 mit den Gleitlagerflächen 11, 12 versehen. Die Gleitlagerflächen 11, 12 entsprechen dem Umfang und dem Aussendurchmesser der Rollen 2. Sie sind als Zylinderausschnitte in den Lagerbock 1 eingeformt. Dabei befindet sich die tiefste Stelle der Einformung zwischen der Peripherie, also dem Aussenrand, des Lagerbockes 1 und seinem Zentrum. Die genannten Kräfte werden somit grundsätzlich senkrecht auf die Gleitlagerflächen 11, 12 übertragen. Damit nun die Gleitreibung der Oberflächen der Rollen 2 an den Gleitlagerflächen 11, 12 nicht zu gross wird und die Betätigung des Presswerkzeuges hemmt, wird die Art der Oberflächen von den Rollen 2 und von den Gleitlagerflächen 11, 12 aufeinander abgestimmt. Sie können gehärtet, gesintert oder beschichtet werden. Beispielsweise eignet sich eine Carbonitrierung, eine Teflonbeschichtung der Gleitlageroberflächen oder dergleichen. Auch die Wahl eines keramischen Werkstoffes für den Lagerbock 1 und Rollen 2 aus Stahl mit gehärteten Oberflächen ist geeignet. Denkbar ist auch die Wahl von anderen, speziellen Materialpaarungen. Beispielsweise kann eine Paarung von verchromten Stahlrollen mit einem Lagerbock aus Nylon-6 zu einem geeigneten Resultat führen. Hierbei erhält man sogar zusätzlich noch eine Schlagdämpfung ohne Beeinträchtigung der Presskraft. Zusätzlich kann je eine Schmiernut 13 je Gleitlagerfläche 11, 12 vorgesehen werden, welche sowohl zur Zufuhr von etwas Schmiermittel, wie auch zur Abfuhr von allfälligem Abrieb dienen kann.The roller holder unit is shown in Figure 4 in view. It consists of a bearing block 1, which corresponds to a cylindrical recess in the cylinder head 51, on the front-outer side. Perpendicular to the bearing block 1 is at least one, but advantageously two parallel retaining plates 3 available. They are fastened by means of screws 4 on the bearing block 1. On the retaining plate 3 respectively between the two retaining plates 3, two rollers 2 are spaced from each other. The rollers 2 are arranged so that they touch each other on a straight line at its periphery. she So support each other and roll off each other. With locking pins 21 they are secured against falling out. Since the locking pins 21 need not absorb any bearing forces, they are weakly dimensioned and in and of themselves do not require any extra support for the rollers 2 on the locking pins 21. It is even possible to carry out a design without drilling through the rollers 2. The geometric arrangement and design of the jaws can prevent falling out of the rollers 2. The safety function in the admission of rotational movement of the rollers 2 is also ensured if the roller inner diameter is much larger than the diameter of the locking pins 21 and thus much game is available, suitable surfaces on the locking pin 21 and the through holes of the rollers 2. It can, for example Steel rollers are used with locking pins 21 made of bronze, which guarantees a permanent self-lubrication here. Crucial new is the storage of the rollers 2 in the roller holder unit. The rollers 2 are based on the one hand, as described, against each other and on the other hand against suitable sliding bearing surfaces 11, 12 on the bearing block 1. The main load of the rollers 2 when pressing the pressing tool is on the one hand by the separation of the Abrollflanken 63 of the jaws 62 generated. The direction of this load takes place via the roller surface in a straight line through the center of the rollers 2 to the respective other role. The rollers 2 are therefore based on each other. This means that this load must be absorbed and transmitted by any storage and thus not by the securing pins 21 and the holding plates 3. A second type of loading of the rollers is done by the relative movement of the piston rod 52 and thus of the bearing block 1. This load is always perpendicular to the bearing block 1. For this purpose, the Bearing 1 with the sliding bearing surfaces 11, 12 provided. The sliding bearing surfaces 11, 12 correspond to the circumference and the outer diameter of the rollers 2. They are formed as cylindrical cutouts in the bearing block 1. In this case, the lowest point of the indentation between the periphery, so the outer edge of the bearing block 1 and its center. The said forces are thus transmitted in principle perpendicular to the sliding bearing surfaces 11, 12. Thus, the sliding friction of the surfaces of the rollers 2 on the sliding bearing surfaces 11, 12 is not too large and inhibits the operation of the pressing tool, the type of surfaces of the rollers 2 and 12 of the sliding bearing surfaces 11, matched. They can be hardened, sintered or coated. For example, a carbonitriding, a Teflon coating of the sliding bearing surfaces or the like is suitable. The choice of a ceramic material for the bearing block 1 and steel rollers 2 with hardened surfaces is suitable. Also conceivable is the choice of other, special material pairings. For example, a pair of chrome steel rollers with a nylon 6 bearing block can provide a suitable result. In this case, one additionally obtains a shock absorption without impairing the pressing force. In addition, depending on a lubrication groove 13 each slide bearing surface 11, 12 are provided, which can serve both for the supply of some lubricant, as well as for the removal of any abrasion.

Aus diesen Ausführen ist klar ersichtlich, dass die gesamte Konstruktion und Ausführung der Rollenhaltereinheit mit den Rollen, deren Lagerung, Sicherung und Haltebleche bedeutend einfacher und leichter ausgelegt werden kann als bisher. Zur Aufnahme der grössten Kräfte stützen sich die Rollen 2 gegenseitig aufeinander ab. Ihre Rotationsachse ist nicht belastet und kann auf eine Sicherung gegen Herausfallen der Rollen 2 beschränkt werden.From these embodiments, it is clear that the entire construction and execution of the roller holder unit with the rollers, their storage, securing and retaining plates can be designed much easier and easier than before. To accommodate the largest forces, the rollers 2 are mutually supported. Your rotation axis is not loaded and can be limited to a backup against falling out of the rollers 2.

Die Ausführung kann weiter vereinfacht werden, indem der Lagerbock 1 und die Gleitlagerflächen 11, 12 aus dem gleichen Material einstückig hergestellt sind. Bei Verwendung von geeignetem Werkstoff können sogar diese Teile zusammen mit den Halteblechen 3 aus einem Stück hergestellt werden.The embodiment can be further simplified by the bearing block 1 and the sliding bearing surfaces 11, 12 are made of the same material in one piece. When using suitable material even these parts can be made together with the holding plates 3 in one piece.
