Description

Die vorliegende Erfindung betrifft ein Preßwerkzeug zum unlösbaren Verbinden beispielsweise eines Fittings und eines in eine Muffe des Fittings eingeführten Metallrohrendes oder anderen Rohrverbindungskonstruktionen, umfassend eine aus mindestens zwei Segmenten bestehende Preßschlinge und eine zangenartige Preßbacke, wobei die im Schließbereich der Preßschlinge liegenden Segmente und die freien Enden der beiden Hälften der Preßbacke mit miteinander korrespondierenden Kopplungsmitteln versehen sind.The present invention relates to a pressing tool for permanent connection for example, one fitting and one inserted into a sleeve of the fitting Metal pipe end or other pipe connection structures comprising one of press sling consisting of at least two segments and a pincer-type press jaw, the segments lying in the closing area of the press sling and the free ends of the two halves of the press jaw with corresponding ones Coupling means are provided.

Preßwerkzeuge der vorerwähnten Art sind in vielerlei Ausführungsformen bekannt und dienen dazu, die Muffe eines Fittings durch Kaltverformung derart auf das Ende eines Metallrohres aufzupressen, daß sich hier eine unlösbare, feste Verbindung ergibt.Pressing tools of the aforementioned type are known in a variety of embodiments and serve to end the sleeve of a fitting by cold working like this of a metal pipe that there is an inseparable, firm connection results.

Es sind Preßwerkzeuge bekannt, bei denen die Preßschlinge lediglich zwei Segmente umfaßt. Derartige Preßschlingen werden insbesondere bei kleineren Durchmessern verwendet. Es sind aber auch Preßschlingen bekannt, die aus mehreren, gelenkig miteinander verbundenen Kettengliedern bestehen, derartige Preßschlingen eignen sich insbesondere für größere Durchmesser.Pressing tools are known in which the press loop is only two segments includes. Press loops of this type are used, in particular, for smaller diameters used. However, press slings are also known which consist of several there are articulated interconnected chain links, such press loops are particularly suitable for larger diameters.

Unabhängig davon, ob die Preßschlingen aus zwei oder mehreren Segmenten bestehen, sind die Kopplungsmittel bei den bekannten Preßwerkzeugen bislang so ausgebildet, daß die Preßbacke ausschließlich in einer gemeinsamen Ebene mit der Preßschlinge an diese Preßschlinge ansetzbar und auch betätigbar ist.Regardless of whether the press slings consist of two or more segments, are the coupling means in the known pressing tools so far trained that the press jaw only in a common plane with the Press sling can be attached to this press sling and can also be actuated.

Die angesprochene Ebene der Preßschlinge und damit auch die bislang alleine nutzbare Ebene der Preßbacke stehen lotrecht zur Längsachse eines Fittings und damit auch lotrecht zur Längsachse eines Metallrohres, welches mit dem Fitting verbunden werden soll. Da derartige Verbindungen vorrangig baustellenseitig bei der Verlegung von Rohrleitungen hergestellt werden müssen, ergibt sich hier aufgrund beengter räumlicher Verhältnisse oft der Nachteil, daß die Preßbacke vom Installateur nur unter schwierigen Bedingungen mit der Preßschlinge koppelbar und betätigbar ist.The addressed level of the press sling and thus also the one that was previously usable alone The level of the press jaw is perpendicular to the longitudinal axis of a fitting and thus also perpendicular to the longitudinal axis of a metal pipe which is connected to the fitting shall be. Since such connections primarily on site at the Laying of pipelines must be made here confined space often the disadvantage that the press jaw by the installer can only be coupled and operated with the press sling under difficult conditions is.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Preßwerkzeug der gattungsgemäßen Art zu schaffen, bei dem die Preßbacke auch unter räumlich beengten Verhältnissen bedienungsfreundlich an die Preßschlinge ansetzbar und betätigbar ist.The present invention has for its object a press tool Generic type to create, in which the press jaw even under tight spaces Conditions easy to use and operate on the press sling is.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Kopplungsmittel gelenkartig ausgebildet sind, so daß die Preßbacke gegenüber der Ebene der Preßschlinge verschwenkbar ist.This object is achieved in that the coupling means are articulated are formed so that the press jaw relative to the plane of the press sling is pivotable.

Hierdurch wird erreicht, daß für den Fall, daß ein Ansetzen der Preßbacke in einer gemeinsamen Ebene mit der Preßschlinge nicht möglich ist, nahezu jeder beliebige andere Winkel der Preßbacke relativ zur Ebene der Preßschlinge einstellbar ist, so daß die Preßbacke nicht nur weitestgehend problemlos an der Preßschlinge ansetzbar, sondern ebenso problemlos dann auch bedienbar ist. Dies erleichtert einem Installateur die Nutzung eines derartigen Preßwerkzeuges in nahezu jeder denkbaren Situation.This ensures that in the event that an application of the press jaw in a common level with the press sling is not possible, almost any other angle of the press jaw is adjustable relative to the plane of the press sling, so that the press jaw can not only be attached to the press sling largely without problems, but is also just as easy to use. This makes it easier for an installer the use of such a pressing tool in almost every conceivable Situation.

Sowohl herstellungstechnisch wie auch unter anwendungstechnischen Gesichtspunkten ist es vorteilhaft, wenn die Kopplungsmittel aus teilkugeligen Nocken einerseits und aus teilkugelartigen Kalotten andererseits bestehen.Both from a manufacturing point of view and from an application point of view it is advantageous if the coupling means consist of partially spherical cams on the one hand and consist of part-spherical domes on the other hand.

Durch eine derartige Gestaltung der Kopplungsmittel ergibt sich eine gute und praxisgerechte Verschwenkbarkeit der Preßbacke gegenüber der Preßschlinge, darüber hinaus lassen sich Kopplungsmittel dieser Art einfach und preiswert an der Preßschlinge einerseits sowie an der Preßbacke andererseits anbringen, da diese Teile üblicherweise im Feingußverfahren hergestellt werden und entsprechende Kopplungsmittel lediglich eine entsprechende Formgebung der Feingußformen erforderlich machen.Such a design of the coupling means results in a good and practical one Pivotal movement of the press jaw relative to the press loop, above In addition, coupling means of this type can be easily and inexpensively attached to the press sling on the one hand and on the press jaw on the other hand, as these parts are usually produced in the investment casting process and corresponding coupling agents only a corresponding shaping of the investment molds is required do.

Die Nocken können an den im Schließbereich liegenden Enden der Segmente und die Kalotten an den freien Enden der beiden Hälften der Preßbacke angebracht sein.The cams can be located at the ends of the segments and in the closing area the domes must be attached to the free ends of the two halves of the press jaw.

Selbstverständlich ist aber hier auch ohne Nachteil eine Umkehr der Anordnung möglich, so daß die Nocken an den beiden Hälften der Preßbacke und die Kalotten an den im Schließbereich liegenden Enden der Segmente angebracht sind.Of course, a reversal of the arrangement is also without disadvantage here possible so that the cams on the two halves of the press jaw and the calottes are attached to the ends of the segments lying in the closing area.

Bei dem in den Figuren 1 bis 5 dargestellten Ausführungsbeispiel der Erfindung besteht das Preßwerkzeug aus einer aus zwei Segmenten 1 und 2 hergestellten Preßschlinge 3 und einer Preßbacke 4, deren beide Hälften 4a und 4b um Achsen 5 zangenartig verschwenkbar sind.In the embodiment of the invention shown in Figures 1 to 5 the pressing tool from a press loop made of two segments 1 and 2 3 and a press jaw 4, the two halves 4a and 4b around axes 5 like pliers are pivotable.

Die Preßschlinge 3 wird in bekannter Weise im geöffneten Zustand, so wie in Figur 1 dargestellt, um einen Fitting 6, der mit einem in dessen Muffe eingeführten Metallrohrendes 7 unlösbar verbunden werden soll, herumgelegt und anschließend werden die beiden Segmente 1 und 2 von Hand oder mit Federkraft so weit zusammengedrückt, daß eine Kopplung zwischen der Preßschlinge 3 und der Preßbacke 4 möglich ist, so wie dies in Figur 2 dargestellt ist. In dieser Position wirken an der Preßschlinge 3 und der Preßbacke 4 vorgesehene, miteinander korrespondierende Kopplungsmittel zusammen. Diese Kopplungsmittel sind erfindungsgemäß gelenkartig ausgebildet, so daß die Preßbacke 4 gegenüber der Ebene der Preßschlinge 3 verschwenkt werden kann.The press sling 3 is opened in a known manner, as in FIG 1 to a fitting 6 which has a metal pipe end inserted into its sleeve 7 to be permanently connected, put around and then the two segments 1 and 2 are pressed together by hand or with spring force, that a coupling between the press sling 3 and the press jaw 4th is possible, as shown in Figure 2. In this position work on the Press sling 3 and the press jaw 4 provided, corresponding to each other Coupling agent together. According to the invention, these coupling means are articulated formed so that the press jaw 4 relative to the plane of the press loop 3rd can be pivoted.

Im dargestellten Ausführungsbeispiel sind die Kopplungsmittel 8 und 9 in Form von teilkugeligen Nocken an den im Schließbereich der Preßschlinge 3 liegenden Enden der Segmente 1 und 2 sowie aus entsprechenden teilkugelartigen Kalotten an den freien Enden der beiden Hälften 4a und 4b des Preßwerkzeuges 4 ausgebildet.In the illustrated embodiment, the coupling means 8 and 9 are in shape of partially spherical cams on the lying in the closing area of the press loop 3 Ends of segments 1 and 2 and from corresponding spherical spherical caps the free ends of the two halves 4a and 4b of the pressing tool 4 are formed.

Durch Betätigung der Preßbacke 4 können die beiden im Bereich der Schließstellung liegenden Enden der Segmente 1 und 2 der Preßschlinge 3 aus der Position gemäß Figur 2 in die Schließposition gemäß Figur 3 zusammengepreßt werden, wodurch entsprechend die Muffe des Fittings 6 durch eine Kaltverformung fest und unlösbar auf das Metallrohrende 7 aufgepreßt wird.By actuating the press jaw 4, the two can in the closed position lying ends of the segments 1 and 2 of the press sling 3 from the position 2 are pressed into the closed position according to FIG. 3, whereby according to the sleeve of the fitting 6 by a cold deformation and is permanently pressed onto the metal pipe end 7.

Von besonderer Bedeutung und von besonderem Vorteil ist es, daß durch die gelenkartige Ausbildung der Kopplungsmittel 8 und 9 die Möglichkeit besteht, die Preßbacke 4 gegenüber der Ebene der Preßschlinge 3 (oder umgekehrt) zu verschwenken, so wie dies in Figur 5 beispielhaft dargestellt ist. Bei beendeten Montageverhältnissen ist es somit möglich, die Preßbacke 4 in der jeweils günstigsten Arbeitsposition mit der Preßschlinge 3 zu koppeln und zu betätigen.It is of particular importance and of particular advantage that the joint-like Training the coupling means 8 and 9, there is the possibility To pivot the press jaw 4 relative to the plane of the press sling 3 (or vice versa), as exemplified in FIG. 5. When installation conditions have ended it is thus possible to press jaw 4 in the most favorable working position to couple with the press sling 3 and to operate.

Das Ausführungsbeispiel gemäß Figur 6 unterscheidet sich vom Ausführungsbeispiel nach den Figuren 1 bis 5 lediglich dadurch, daß die Preßschlinge 3 aus mehreren Segmenten 1, 2, 10 und 11 besteht, wobei die mit dem Bezugszeichen 1 und 2 bezeichneten Segmente wiederum im Schließbereich der Preßschlinge 3 liegen und mit der Preßbacke 4 koppelbar sind.The exemplary embodiment according to FIG. 6 differs from the exemplary embodiment according to Figures 1 to 5 only in that the press sling 3 from several There are segments 1, 2, 10 and 11, with the reference numerals 1 and 2 designated segments are in turn in the closing area of the press sling 3 and can be coupled with the press jaw 4.

Auch hier sind die Kopplungsmittel 8 und 9 gelenkartig ausgebildet und bestehen, wie schon beim Ausführungsbeispiel nach den Figuren 1 bis 5 beschrieben, aus teilkugelartigen Nocken an den im Schließbereich liegenden Enden der Segmente 1 und 2 und teilkugeligen Kalotten 9 an den freien Enden der beiden Hälften 4a und 4b der Preßbacke 4.Here too the coupling means 8 and 9 are articulated and exist, as already described in the exemplary embodiment according to FIGS. 1 to 5 Partially spherical cams at the ends of the segments 1 in the closing area and 2 and spherical spherical caps 9 at the free ends of the two halves 4a and 4b of the press jaw 4.

Hiervon unterscheidet sich das Ausführungsbeispiel gemäß Figur 7 lediglich dadurch, daß die teilkugelartigen Nocken der Kopplungsmittel 8 und 9 an den freien Enden der beiden Hälften 4a und 4b der Preßbacke 4 angebracht sind, während die teilkugelartigen Kalotten 9 an den im Schließbereich liegenden Enden der Segmente 1 und 2 der Preßschlinge 3 vorgesehen sind.The exemplary embodiment according to FIG. 7 differs from this only in that that the part-spherical cams of the coupling means 8 and 9 on the free Ends of the two halves 4a and 4b of the press jaw 4 are attached while the Partial spherical domes 9 at the ends of the segments lying in the closing area 1 and 2 of the press sling 3 are provided.
