Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum pneumatischen Betätigen eines druckbeaufschlagten Werkzeuges gemäss dem Oberbegriff nach Anspruch 1 sowie eine pneumatische Zange.The present invention relates to a device for pneumatic Operating a pressurized tool according to the preamble of claim 1 and a pneumatic pliers.

Pneumatische Zangen zum Verpressen und Festklemmen von Klemmringen, Bolzen, Kabelschuhen, Briden etc. sind bekannt. Insbesondere bekannt sind pneumatische Zangen in der Automobilindustrie, wo diese Zangen für das Festklemmen von Klemmringen bei der Montage von Schläuchen, Faltbälgen etc. an Stutzen, Gelenkwellen und dergleichen verwendet werden.Pneumatic pliers for pressing and clamping clamping rings, Bolts, cable lugs, clips etc. are known. In particular pneumatic pliers are known in the automotive industry, where these pliers are used for clamping clamping rings the assembly of hoses, bellows etc. on sockets, cardan shafts and the like can be used.

Aus der DE 37 42 782 ist eine Druckmittelzange für Federbandschellen bekannt, mit einem ventilgesteuerten Druckmittelanschluss und einem keilförmigen Vorschubglied.DE 37 42 782 is a pressure medium pliers for spring band clamps known, with a valve-controlled pressure medium connection and a wedge-shaped feed member.

Im deutschen Gebrauchsmuster 89 00 250.4 wird eine ähnliche Druckmittelzange beschrieben, in welcher mehrere in Serie hintereinander angeordnete Antriebskolben für die Erhöhung der Schubkraft vorgesehen sind, wobei die Kolbenstange jedes einzelnen Kolbens in einer Zylinderwandung geführt ist. Ebenfalls mehrere in Reihe angeordnete Druckkolben aufweisende Druckmittelzangen sind in der DE 195 19 543 und dem GM 295 09 976 beschrieben.A similar one is used in German utility model 89 00 250.4 Pressure medium pliers described in which several in series in a row arranged drive piston for increasing the Thrust is provided, with the piston rod each Piston is guided in a cylinder wall. Likewise several pressure medium pliers arranged in series with pressure pistons are described in DE 195 19 543 and GM 295 09 976.

Das Prinzip der Krafterhöhung durch mehrere in Reihe angeordnete kraftschlüssige Kolben für das Erzeugen einer translatorischen Schubkraft ist bereits seit langem bekannt. Die Umwandlung der translatorischen Kraft, insbesondere bei pneumatischen Zangen, in eine bogenförmige Kraft geschieht im Zangenkopf mittels eines Vorschubwerkzeuges, wie eines Keils. Die Verpressungskraft an den Zangenbacken ist u.a. von der Schubkraft des Vorschubwerkzeuges abhängig.The principle of increasing the force through several arranged in series positive piston for generating a translational Thrust has been known for a long time. The transformation the translational force, especially with pneumatic Pliers, in an arcuate force happens in the pliers head by means of a feed tool, such as a wedge. The compressive force on the jaws of the pliers from the thrust of the Feed tool dependent.

Die aus dem Stand der Technik bekannten Konzepte weisen starke Streuungen der Verpressungskräfte auf, behalten in der Regel ihre Verpressungskraft bei gleichem Druck nicht aufrecht und verlieren ihre Verpressungskraft über die Lebensdauer. Ein weiterer Nachteil liegt darin, dass die bekannten Verpressungszangen nicht wartungsfrei sind.The concepts known from the prior art are strong Scattering of the compressive forces usually remains their compressive force is not upright at the same pressure and lose their compressive force over their lifespan. Another The disadvantage is that the known crimping pliers are not maintenance-free.

Es ist daher eine Aufgabe der vorliegenden Erfindung, ein pneumatisch betriebenes Druckmittelwerkzeug der bekannten Art zu schaffen, ohne die oben erwähnten Nachteile.It is therefore an object of the present invention to provide a pneumatic operated pressure fluid tool of the known type create without the disadvantages mentioned above.

Erfindungsgemäss wird die gestellte Aufgabe mittels einer Vorrichtung gemäss dem Wortlaut nach Anspruch 1 gelöst.According to the invention, the object is achieved by means of a device solved according to the wording of claim 1.

Vorgeschlagen wird eine Vorrichtung zum pneumatischen Betätigen eines druckbeaufschlagten Werkzeuges, wie insbesondere einer pneumatischen Zange, aufweisend einen Zylinder mit einem oder mehreren in Reihe angeordneten pneumatisch betriebenen, kraftschlüssigen Kolben zur Erzeugung einer translatorischen Kraft, deren jeweilige Kolbenstangen in einem Führungsring bzw. einer Zylinderwandung gehalten und geführt sind sowie ein mit dem oder den Kolben wirkverbundenes Vorschubglied für die Betätigung des Werkzeuges. Dabei wird erfindungsgemäss vorgeschlagen, dass peripher aussen umgreifend an dem oder den Kolben je mindestens zwei Ringe gegen die Zylinderrohrinnenwandung gerichtet angeordnet sind.A device for pneumatic actuation is proposed a pressurized tool, such as one in particular pneumatic pliers, comprising a cylinder with one or several pneumatically operated, non-positive, arranged in series Pistons for generating a translatory force, their respective piston rods in a guide ring or one Cylinder wall are held and guided and one with the or the piston operatively connected feed member for actuation of the tool. It is proposed according to the invention that at least peripherally encompassing the piston or pistons two rings directed against the inside of the cylinder tube are arranged.

Gemäss einer Ausführungsvariante der vorliegenden Erfindung ist mindestens einer der Ringe ein Kolbenführungsband. According to one embodiment variant of the present invention at least one of the rings has a piston guide band.

Gemäss einer weiteren Ausführungsvariante ist mindestens einer der Ringe eine sogenannte Lippendichtung.According to a further embodiment variant, at least one is the rings a so-called lip seal.

Lippendichtungen weisen geringere Haftreibung sowie niedrigere dynamische Reibung auf. Kolbenführungsbänder vermeiden das Berühren des Kolbens bzw. des Kolbenbodens oder -tellers am Zylinder und tragen damit zur Leichtlaufeigenschaft des Kolbens bei. Letztlich tragen diese Massnahmen zur Wartungsfreiheit der erfindungsgemässen Vorrichtung bei.Lip seals have lower static friction as well as lower dynamic friction on. Piston guide bands avoid touching the piston or the piston crown or plate on the cylinder and thus contribute to the smooth running properties of the piston at. Ultimately, these measures contribute to the freedom from maintenance of the device according to the invention.

Um die translatorische Kraftkonstanz der einzelnen in Reihe angeordneten Kolben zu garantieren, wird u.a. der zuvorige Kolben im Folgekolben geführt und mittels eines Abdichtelementes, z.B. eines O-Ringes, abgedichtet.To ensure the translational force constancy of the individual arranged in series Guaranteeing pistons the previous piston guided in the follower piston and by means of a sealing element, e.g. an O-ring, sealed.

Weitere bevorzugte Ausführungsvarianten der erfindungsgemässen Vorrichtung sind in den abhängigen Ansprüchen charakterisiert. Die erfindungsgemässe Vorrichtung eignet sich insbesondere für eine pneumatische Zange zum Anordnen, Verpressen oder Festklemmen von Klemmringen, Bolzen, Kabelschuhen, Briden und dergleichen.Further preferred embodiments of the inventive Devices are characterized in the dependent claims. The device according to the invention is particularly suitable for a pneumatic pliers for arranging, pressing or clamping of clamping rings, bolts, cable lugs, clips and the like.

Der grosse Vorteil der erfindungsgemässen Vorrichtung liegt darin, dass die translatorische Schubkraft bei gleichem pneumatischem Druck konstant bleibt. Damit ergeben sich aber auch konstante Verpressungskräfte bei baugleichen Zangen und bei gleichem pneumatischem Druck. Schlussendlich bleiben die Verpressungskräfte über die gesamte Lebensdauer der erfindungsgemäss vorgeschlagenen Vorrichtung konstant.The great advantage of the device according to the invention lies in that the translational thrust with the same pneumatic Pressure remains constant. But this also results constant pressing forces with identical pliers and with same pneumatic pressure. Ultimately, the compression forces remain over the entire life of the invention proposed device constant.

Dadurch, dass das zu betreibende Werkzeug vorzugsweise auswechselbar an der Vorrichtung angeordnet werden kann, ist die erfindungsgemässe Vorrichtung auch universell für die Betätigung von pneumatischen Werkzeugen verwendbar. Mit anderen Worten ist die vorliegende Erfindung nicht auf Klemmwerkzeuge beschränkt, sondern kann für irgendwelche Werkzeuge verwendet werden, welche durch pneumatisch betriebene und mittels der translatorischen Schubkraft betätigbare Vorschubglieder betrieben werden können.The fact that the tool to be operated is preferably interchangeable can be arranged on the device is the inventive Device also universal for actuation usable with pneumatic tools. In other words the present invention is not restricted to clamping tools, but can be used for any tools which by pneumatically operated and by means of translatory Pushable actuable feed elements are operated can.

in enlargement, a section of the representation of Fig. 1st

Fig. 1 zeigt im Längsschnitt eine pneumatisch betätigbare und mittels Druck antreibbare Zange 1 für das Verbauen von Rohrschellen, Schlauchbriden, Klemmringen etc. In einem Zylinder 3 sind mehrere in Serie bzw. in Reihe hintereinander angeordnete Kolben 5 angeordnet. Der Vorteil dieser in Reihe angeordneter Kolben liegt in einer Kraftsteigerung, indem die erzeugbare translatorische Kraft wesentlich höher ist als bei Verwendung nur eines einzigen Kolbens. Ein Grund dafür liegt in der Vergrösserung der Kolbenfläche.Fig. 1 shows in longitudinal section a pneumatically operated and pliers 1 which can be driven by pressure for the installation of pipe clamps, Hose clamps, clamping rings etc. in a cylinder 3 are several in series or in a row Piston 5 arranged. The advantage of this arranged in series Piston lies in an increase in power by the producible translatory force is significantly higher than when used just a single piston. One reason for this is the enlargement the piston surface.

Am hinteren Ende der handbetätigbaren pneumatischen Zange ist ein Anschluss 8 vorgesehen für das Anschliessen der Zange an ein Druckmittel, wie beispielsweise an Pressluft, wobei die Druckmittelzufuhr mittels eines Ventilhebels 7 für die Betätigung eines Ventils 9 geöffnet bzw. entlüftet werden kann. Die einzelnen Kolben 5 weisen einen Durchgang 10 durch die Kolbenstangen 6 auf, für das Hindurchtreten des Druckmittels. Im Bereich des frontseitigen Endes der Kolbenstangen 6 sind radial nach aussen gerichtet Austrittsöffnungen 11 vorgesehen, für das Austreten der Druckluft und für die Betätigung des in Richtung Zangenwerkzeug nächsten Kolbens 5. Durch die Druckluft wird der nächstfolgende Kolben 6 vorwärts getrieben, und der Durchtritt der Druckluft durch den Durchgang der nächstfolgenden Kolbenstange wiederholt sich in analoger Art und Weise.At the rear end of the manual pneumatic pliers a connection 8 is provided for connecting the pliers a pressure medium, such as compressed air, the Pressure medium supply by means of a valve lever 7 for actuation of a valve 9 can be opened or vented. The individual pistons 5 have a passage 10 through the piston rods 6 on, for the passage of the pressure medium. In the area the front end of the piston rods 6 are radial outward openings 11 provided for the Escape the compressed air and for actuating the in the direction Pliers tool next piston 5. The next piston 6 driven forward, and the passage the compressed air through the passage of the next piston rod repeats itself in an analogous manner.

Für ein verkantsicheres Führen der Kolbenstange sind in den Folgekolben 5,34 Zentrierbohrungen 28 vorhanden, die mittels eines O-Ringes 25 abgedichtet sind. Die Zylinderdeckel 13, welche mittels Sicherungsringen 14 fest positioniert sind, dienen der fluidischen Trennung der einzelnen Kolben und sind mit einem Dicht-Abstreifring 24 abgedichtet, so dass jeder Kolben mit seinem dazugehörigen Zylinderdeckel 13 eine fluidische Einheit darstellt.In order to prevent the piston rod from tilting, Follower piston 5.34 centering bores 28 are present, which means an O-ring 25 are sealed. The cylinder cover 13, which are firmly positioned by means of retaining rings 14 the fluidic separation of the individual pistons and are with a Sealing wiper ring 24 sealed so that each piston has its associated cylinder cover 13 is a fluidic unit represents.

In Zangenwerkzeugrichtung am den vordersten Kolben 5 folgt der sogenannte Keilkolben 34, an dessen Frontseite ein keilförmiges Vorschubglied 35 angeordnet ist, zum Betätigen des Zangenkopfes 38. Durch den mittels des Druckmittels, wie beispielsweise der Pressluft, vorwärts getriebenen Keil 35 werden die beiden beispielsweise im Bolzen 39 gelagerten Zangenbacken 36 im hinteren Bereich auseinandergetrieben, indem sich die Keilfläche zwischen zwei Rollen 40 schiebt. Gleichzeitig werden die beiden Zangenbacken 36 frontseitig in Schliessrichtung zusammengetrieben, beispielsweise für das Festklemmen einer Klemmbride bzw. für das Verpressen von Ohrklemmen oder dergleichen durch Betätigen von Zangen 42. In the pliers tool direction on the foremost piston 5 follows so-called wedge piston 34, on the front of a wedge-shaped Feed member 35 is arranged for actuating the pliers head 38. By means of the pressure medium, such as the Compressed air, forward-driven wedge 35, for example, the two pliers jaws 36 mounted in the pin 39 in the rear Area separated by the wedge surface between pushes two rollers 40. At the same time, the two Pliers jaws 36 driven together in the closing direction on the front, for example for clamping a clamping bracket or for pressing ear clips or the like by pressing of pliers 42.

Der Zangenkopf 38 ist vorzugsweise mittels einer Überwurfmutter 43 auswechselbar mit dem Zylinder 3 verbunden. Zusätzlich sind die Zangenbacken 36 seitlich mittels Abdeckblechen 46 gegen Berühren (Unfallschutz) bzw. Verschmutzung geschützt.The pliers head 38 is preferably by means of a union nut 43 interchangeably connected to the cylinder 3. In addition are the jaws 36 laterally by means of cover plates 46 against contact (Accident protection) or pollution protected.

Anhand von einem Ausschnitt aus Fig. 1 soll nun im Längsschnitt von Fig. 2 auf die erfindungswesentlichen Merkmale eingegangen werden. So weist der Kolben 5 in Richtung Zylinderrohrwandung 3 eine Kolbendichtung 22 sowie ein Kolbenführungsband 23 auf. Bei der Kolbendichtung 22 handelt es sich vorzugsweise um eine sogenannte Lippendichtung. Insbesondere die Verwendung von Lippendichtungen ergibt geringe Haftreibung sowie niedere dynamische Reibung. Das Kolbenführungsband 23 vermeidet das Berühren des Kolbens am Zylinderrohr und trägt damit zur Leichtlaufeigenschaft der Kolben bei und führt weiter zur Wartungsfreiheit des erfindungsgemäss vorgeschlagenen Zangenwerkzeuges.Based on a section of Fig. 1 is now in longitudinal section of Fig. 2 discussed the features essential to the invention become. The piston 5 points in the direction of the cylinder tube wall 3 a piston seal 22 and a piston guide band 23. at the piston seal 22 is preferably a so-called Lip seal. In particular the use of lip seals results in low static friction and low dynamic Friction. The piston guide band 23 avoids touching of the piston on the cylinder tube and thus contributes to the smooth running property the piston and leads to freedom from maintenance of the pliers tool proposed according to the invention.

Ein weiteres erfinderisches Merkmal liegt in der Verwendung einer Lippendichtung 24, mittels welcher die Kolbenstange 6 gegenüber dem Zylinderdeckel 13 abgedichtet ist. Weiter erstreckt sich die Kolbenstange 6 bis in den Kolbenboden 12 hinein und weist im Randbereich des Frontendes eine zusätzliche Dichtung 25 auf, wie beispielsweise einen sogenannten O-Rohr. Diese Massnahme führt zur konstanten translatorischen Schubkraft bei gleichem pneumatischen Druck.Another inventive feature is the use of a Lip seal 24, by means of which the piston rod 6 opposite the cylinder cover 13 is sealed. Further extends the piston rod 6 into and into the piston crown 12 has an additional seal in the edge area of the front end 25, such as a so-called O-tube. This Measure leads to constant translatory thrust same pneumatic pressure.

Im übrigen sind in Fig. 2 analoge Teile zu Fig. 1 mit denselben Bezugszeichen versehen, womit auf eine Wiederholung der Funktionsweise der erfindungsgemässen Druckmittelvorrichtung verzichtet werden kann. Otherwise, in FIG. 2, parts analogous to FIG. 1 are the same Provide reference numerals, thereby repeating the operation the pressure medium device according to the invention is dispensed with can be.
