Wellrohre werden in vielfältiger Art und Weise eingesetzt. Beispielsweise kommen Wellrohre in Fluidverteilervorrichtungen für häusliche oder industrielle Zwecke zum Einsatz. Wellrohre bieten sich hierzu an, weil sie aufgrund ihres wellenförmig wechselnden Durchmessers relativ flexibel sind.Corrugated pipes are used in a variety of ways. For example, corrugated pipes are used in fluid distribution devices for domestic or industrial purposes. Corrugated pipes offer this because they are relatively flexible due to their wavy changing diameter.
Die Wellrohre werden üblicherweise auf eine gewünschte Länge abgelängt. Um zwei Wellrohre miteinander zu verbinden, lassen sich die freien Enden der Wellrohre mit Schraubarmaturen oder Fittings versehen. Um die Fittings oder Armaturen an den Wellrohren zu befestigen, werden die Enden gestaucht, so dass beispielsweise zwei oder drei Wellen des Wellrohres in axialer Richtung gegeneinander gepresst sind. Dadurch ist ein relativ belastbarer Bund ausgebildet, welcher eine Anlagefläche für ein Fitting oder eine Armatur bildet.The corrugated pipes are usually cut to a desired length. To connect two corrugated pipes with each other, the free ends of the corrugated pipes can be provided with screw fittings or fittings. In order to fasten the fittings or fittings to the corrugated pipes, the ends are compressed, so that, for example, two or three shafts of the corrugated pipe are pressed against each other in the axial direction. As a result, a relatively resilient collar is formed, which forms a contact surface for a fitting or a fitting.

In der Praxis wird häufig die Situation vorgefunden, dass Wellrohre an schwer zugänglichen Orten zu verlegen sind. Beispielsweise kann es sein, dass eine Überkopfmontage durchzuführen ist oder die Bewegungsfreiheit für einen Monteur insgesamt relativ eingeschränkt ist.

Der Werkstückhalter ist dadurch nach dem Einführen in die Befestigungsposition in seiner axialen Lage fixiert, so dass ein ungewolltes Lösen des Werkstückhalters von der Vorrichtung vermieden ist.It is envisaged that in the mounting position of the workpiece holder is inserted into a through hole of the support member and by turning the workpiece holder relative to the support member, preferably by a predetermined Angle of rotation, the workpiece holder can be locked in the mounting position. The workpiece holder is thereby fixed in its axial position after insertion into the mounting position, so that an unintentional release of the workpiece holder is avoided by the device.
Zum Arretieren des Werkstückhalters an dem Trägerteil ist ein Bajonettverschluss vorgesehen. In technisch einfacher Weise ist ein solcher Bajonettverschluss realisiert, wenn nach einer Ausgestaltung der Erfindung der Werkstückhalter wenigstens einen seitlich nach außen wegstehenden Vorsprung aufweist, welcher mit einer Vertiefung am Innenumfang der Durchgangsöffnung korrespondiert. Es ist dadurch der Werkstückhalter mit seinem Vorsprung in die Befestigungsposition an dem Trägerteil bringbar und durch Verdrehen des Werkstückhalters gegen das Trägerteil der Vorsprung gegen die Berandung der Durchgangsöffnung in Anlage bringbar, in welcher dann die Arretierung vorliegt.For locking the workpiece holder on the support part a bayonet lock is provided. In a technically simple manner, such a bayonet closure is realized when according to one embodiment of the invention, the workpiece holder has at least one laterally outwardly projecting projection which corresponds to a recess on the inner circumference of the through hole. It is thereby the workpiece holder can be brought with its projection in the mounting position on the support member and brought by rotation of the workpiece holder against the support member of the projection against the boundary of the through hole in abutment, in which then the lock is present.
Um den Werkstückhalter auch in die andere axiale Richtung in seiner Bewegung zu begrenzen bzw. eine solche Bewegung zu vermeiden, weist nach einer weiteren Ausgestaltung der Erfindung der Werkstückhalter einen Anschlag auf, durch welchen der Einschiebeweg des Werkstückhalters in die Durchgangsöffnung begrenzt ist.In order to limit the workpiece holder in the other axial direction in its movement or to avoid such movement, according to a further embodiment of the invention, the workpiece holder has a stop by which the insertion path of the workpiece holder is limited in the passage opening.
Es bietet sich an, dass der Werkstückhalter durch wenigstens zwei Teile gebildet ist, welche gemeinsam eine ringförmige Aufnahme für das Wellrohr ausbilden. Beispielsweise können die Teile jeweils als Halbschale ausgebildet sein. Die Teile bzw. Halbschalen können als Gleichteile hergestellt sein, so dass sie herstellungstechnisch einfach und mit geringem Kostenaufwand zu realisieren sind.It is advisable that the workpiece holder is formed by at least two parts, which together form an annular receptacle for the corrugated pipe. For example, the parts may each be formed as a half-shell. The parts or half-shells can be made as equal parts, so that they manufacture technology are easy to implement and with low cost.
Durch die Mehrteiligkeit des Werkstückhalters ist die Aufnahme eines zu stauchenden Wellrohres in der Halteeinrichtung erleichtert. Der Monteur braucht dazu lediglich die Teile des Werkstückhalters an dem Wellschlauch in der vorgegebenen Art und Weise zu positionieren, damit er dann den dadurch gebildeten Werkstückhalter zusammen mit dem Wellschlauch an der Vorrichtung montieren kann.Due to the multi-part of the workpiece holder, the inclusion of a corrugated pipe to be compressed in the holding device is facilitated. The installer only needs to position the parts of the workpiece holder on the corrugated tube in the predetermined manner so that he can then mount the workpiece holder formed thereby together with the corrugated hose to the device.
Um die Teile des Werkstückhalters an dem Wellrohr in der vorgegebenen Art und Weise zu positionieren, bietet es sich an, dass jeweils zwei zueinander benachbarte Teile wenigstens ein Magnetelement aufweisen, so dass die Teile mittels Magnetkraft gegeneinander gehalten sind.In order to position the parts of the workpiece holder on the corrugated pipe in the predetermined manner, it is advisable that in each case two mutually adjacent parts have at least one magnetic element, so that the parts are held against each other by means of magnetic force.
In einfacher Weise lässt sich eine solche Verbindung realisieren, wenn die Teile selbst aus Metall, insbesondere ferromagnetischem Metall sind.In a simple way, such a connection can be realized if the parts themselves are made of metal, in particular ferromagnetic metal.
Nach einer weiteren Ausgestaltung der Erfindung ist es vorgesehen, dass der Werkstückhalter wenigstens einen Vorsprung zum Eingreifen in ein Wellental des Wellrohres hat. Dadurch ist in technisch einfacher Weise eine Arretierung des Wellrohres in axialer Richtung gegenüber dem Werkstückhalter und damit gegenüber der Vorrichtung realisiert. Durch den mittels des Vorsprunges erzeugten Formschluss ist zugleich eine besonders haltbare Fixierung des Wellrohres erreicht.According to a further embodiment of the invention, it is provided that the workpiece holder has at least one projection for engaging in a trough of the corrugated pipe. As a result, a locking of the corrugated pipe in the axial direction relative to the workpiece holder and thus realized with respect to the device in a technically simple manner. Due to the positive connection generated by the projection a particularly durable fixation of the corrugated pipe is achieved at the same time.
Es bietet sich an, dass der Vorsprung zumindest teilweise umlaufend ist. Der umlaufende Vorsprung kann dabei wenigstens eine oder mehrere Unterbrechungen aufweisen. Dazu wird das zu stauchende Wellrohr auch bei den im Zuge des Stauchvorganges auftretenden hohen Reaktionskräften in ausreichendem Maße in der vorbestimmten Position gehalten.It is advisable that the projection is at least partially circumferential. The circumferential projection can at least have one or more interruptions. For this purpose, the corrugated tube to be crushed is kept sufficiently in the predetermined position even with the high reaction forces occurring during the upsetting process.
Insbesondere dient die nach außen weisende Stirnseite des Vorsprunges als Gegendrückteil, gegen welches die zu stauchende Welle des Wellrohres mittels des Drückteiles gedrückt wird.In particular, the outwardly facing end face of the projection serves as a counter-back against which the shaft of the corrugated tube to be crushed is pressed by means of the pressing member.
Nach einer weiteren Ausgestaltung der Erfindung weist die Vorrichtung ein Schraubgetriebe auf, dessen translatorisch wirkender Ausgang mit dem Drückteil wirkverbunden ist, so dass eine Verschiebebewegung des Drückteils durch eine rotatorische Antriebsbewegung bewirkt wird. Dadurch wird bereits bei einer relativ geringen Betätigungskraft eine relativ große Umformkraft von dem Drückteil erzeugt. Zugleich ist eine exakte und relativ positionsgenaue Bewegung des Drückteiles ermöglicht, so dass eine hohe Maßgenauigkeit im Hinblick auf die auszuführende Stauchung des Wellrohres erzielt wird.According to a further embodiment of the invention, the device has a helical gear, whose translationally acting output is operatively connected to the pressing member, so that a displacement movement of the pressing member is effected by a rotary drive movement. As a result, a relatively large forming force is generated by the pressing member even at a relatively low operating force. At the same time an exact and relatively positionally accurate movement of the pressing member is made possible, so that a high dimensional accuracy is achieved with regard to the compression of the corrugated pipe to be executed.
Insbesondere ist das Schraubgetriebe zum Verschieben des Drückteils in Richtung der Drehachse der Antriebsbewegung ausgebildet. Dadurch ist ein hoher Wirkungsgrad bei der Kraftübertragung durch das Schraubgetriebe erreicht. Dem Monteur wird damit das Ausformen des Wellrohres an seinem Ende weitergehend erleichtert, um eine hochwertige Stauchung des Wellrohrendes herbeizuführen.In particular, the helical gear is designed for displacing the pressing part in the direction of the axis of rotation of the drive movement. As a result, a high efficiency in the power transmission is achieved by the helical gear. The installer is thus the shaping of the corrugated pipe at its end further facilitated to bring about a high-quality compression of the corrugated pipe end.
Nach einer Ausgestaltung der Erfindung ist es vorgesehen, dass das Schraubgetriebe eine auf das Drückteil wirkende Gewindespindel aufweist oder daraus gebildet ist, dessen Gewinde mit einem Gegengewinde eines Trägerteils zusammenwirkt. Dadurch ist das Schraubgetriebe in technisch einfacher Weise realisiert. Das Gegengewinde kann an dem Trägerteil ausgeformt sein. Alternativ kann ein gewindeführendes Bauteil, wie beispielsweise eine Gewindebuchse, vorgesehen sein, welche drehfest in oder an dem Trägerteil befestigt ist.According to one embodiment of the invention, it is provided that the helical gear has a threaded spindle acting on the pressing member or is formed therefrom, whose Thread cooperates with a mating thread of a support member. As a result, the helical gear is realized in a technically simple manner. The mating thread can be formed on the carrier part. Alternatively it can be provided a threaded component, such as a threaded bush, which is rotatably mounted in or on the support member.
Es bietet sich an, dass das Drückteil an der Gewindespindel angebunden ist. Dadurch ist das Drückteil verliersicher gehalten, so dass auf eine Einhausung um des Drückteil oder eine zusätzliche Führung des Drückteils verzichtet werden kann. Eine Einhausung für das Drückteil oder eine zusätzliche Führung für das Drückteil kann selbstverständlich auch vorgesehen sein.It is advisable that the pressing member is connected to the threaded spindle. As a result, the pressing member is held captive, so that can be dispensed with an enclosure to the pressing member or an additional guidance of the pressing member. An enclosure for the pressing member or an additional guide for the pressing member can of course also be provided.
Es bietet sich ferner an, dass das Drückteil gegenüber der Gewindespindel drehbar ist. Dadurch ist sichergestellt, dass das Drückteil relativ gegenüber der Gewindespindel rotationsfrei bleibt, wenn die Gewindespindel betätigt wird und das Drückteil auf das Ende des Wellrohres drückt.It is also advisable that the pressing member is rotatable relative to the threaded spindle. This ensures that the pressing member remains rotationally free relative to the threaded spindle when the threaded spindle is actuated and presses the pressing member on the end of the corrugated tube.
In technisch einfacher Weise lässt sich eine Anbindung des Drückteiles an der Gewindespindel realisieren, wenn das Drückteil eine Aufnahme aufweist, in welche das Ende der Gewindespindel eingesteckt ist.In a technically simple way can be a connection of the pressing member to realize the threaded spindle when the pressing member has a receptacle in which the end of the threaded spindle is inserted.
Dazu können ergänzend Mittel vorgesehen sein, um die Verbindung bzw. Steckverbindung von Drückteil und Gewindespindel gegen ein Lösen in axialer Richtung zu sichern. Beispielsweise kann ein Stiftelement, eine Madenschraube oder dergleichen Vorsprung an dem Drückteil vorgesehen sein, welcher in eine Vertiefung, insbesondere umlaufende Nut, an der Gewindespindel eingreift.For this purpose, additional means may be provided to secure the connection or plug connection of the pressing member and the threaded spindle against loosening in the axial direction. For example, a pin element, a grub screw or the like projection may be provided on the pressing member, which engages in a recess, in particular circumferential groove on the threaded spindle.
Sofern die Gewindespindel mit einem Ende auf das Drückteil wirkt, kann es vorgesehen sein, dass das Ende nach außen gewölbt ausgebildet ist. Dadurch drückt die Gewindespindel mit einer relativ kleinen Kontaktfläche gegen das Drückteil, so dass sich die Vorrichtung nach einer ausgeführten Stauchung eines Wellrohres leicht aus seinem Klemmzustand lösen lässt.If the threaded spindle acts with one end on the pressing member, it may be provided that the end is curved outwardly. Thereby, the threaded spindle presses with a relatively small contact surface against the pressing member, so that the device can easily be released from its clamping state after an executed compression of a corrugated pipe.
Dies lässt sich in technisch einfacher Weise auch realisieren, wenn nach einer weiteren Ausgestaltung der Erfindung zwischen dem Ende der Gewindespindel und dem Drückteil ein Kugelelement angeordnet ist. Das Ende der Gewindespindel kann dann im Wesentlichen eben ausgebildet sein. Um den Effekt des leichten Lösens zu erreichen, reicht es aus, ein handelsübliches Kugelelement zwischenzuschalten und auf diese Art und Weise die Kraftübertragung von der Gewindespindel auf das Drückteil auf eine relativ kleine Übertragungsfläche zu reduzieren.This can also be realized in a technically simple manner if, according to a further embodiment of the invention, a ball element is arranged between the end of the threaded spindle and the pressing part. The end of the threaded spindle can then be formed essentially flat. To achieve the effect of easy release, it is sufficient to interpose a commercially available ball element and in this way to reduce the transmission of force from the threaded spindle to the pressing member to a relatively small transfer surface.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass das Drückteil relativ gegenüber der Gewindespindel über einen vorgegebenen Stellweg in axialer Richtung bewegbar ist. Dadurch ist bewusst in einem gewissen Maße eine Bewegbarkeit des Drückteiles relativ gegenüber der Gewindespindel in Richtung der Längsachse der Gewindespindel zugelassen, beispielsweise um ein zu stauchendes Wellrohr in einfacher Weise in die Halteeinrichtung montieren zu können, ohne dazu die Gewindespindel zurückdrehen zu müssen. Es ist dadurch begünstigt, dass der Monteur nach dem Stauchen eines Wellrohrendes lediglich die Klemmverbindung gegenüber dem Wellrohrende zu lösen braucht und dann ohne umfangreiches Zurückdrehen der Gewindespindel zugleich das nächste Wellrohr zum erneuten Stauchen in die Halteeinrichtung aufnehmen kann.A further embodiment of the invention provides that the pressing member is movable relative to the threaded spindle over a predetermined travel in the axial direction. As a result, to a certain extent a mobility of the pressing member relative to the threaded spindle in the direction of the longitudinal axis of the threaded spindle is allowed, for example, to be able to mount a corrugated tube to be easily mounted in the holding device, without having to turn back the threaded spindle. It is thereby favored that the fitter after upsetting a Wellrohrendes only the clamp connection with respect to the It is then necessary to release the corrugated pipe end and then be able to accommodate the next corrugated pipe for re-upsetting into the holding device without extensive turning back of the threaded spindle at the same time.
Um ein störendes Klappern des Drückteiles aufgrund ungewollter axialer Bewegungen des Drückteils gegenüber der Gewindespindel zu vermeiden, kann es vorgesehen sein, dass das Drückteil und die Gewindespindel gegen die Kraft eines Federelements aufeinander zu bewegbar sind. Auch kann es vorgesehen sein, dass das Federelement vorgespannt ist, so dass durch die Vorspannkraft des Federelementes das Drückteil in dem größtmöglichen axialen Abstand zu der Gewindespindel gehalten ist.In order to avoid a disturbing rattling of the pressing member due to unwanted axial movements of the pressing member relative to the threaded spindle, it can be provided that the pressing member and the threaded spindle against the force of a spring element are movable towards each other. It can also be provided that the spring element is biased, so that is held by the biasing force of the spring element, the pressing member in the largest possible axial distance from the threaded spindle.
Nach einer weiteren Ausgestaltung der Erfindung ist ein Griffteil zum Handhalten der Vorrichtung beim Stauchen des Wellrohres vorgesehen. Insbesondere ist das Griffteil ein Bestandteil der Vorrichtung, beispielsweise an der Vorrichtung angeordnet. Durch das Griffteil ist die Benutzung der Vorrichtung für einen Monteur erleichtert, da der Monteur das Stauchen eines Wellrohrendes ohne Ablage der Vorrichtung auf einer Unterlage, wie beispielsweise einem Arbeitstisch, benutzen kann. Durch das Griffteil kann der Monteur die Vorrichtung problemlos in einer Überkopfposition halten. Durch das Griffteil ist es möglich, dass der Monteur direkt vor Ort an der Baustelle und dort auch in schlecht zugänglichen Bereichen bereits verlegte Wellrohre stauchen ordnungsgemäß stauchen kann.According to a further embodiment of the invention, a handle for holding the device when upsetting the corrugated pipe is provided. In particular, the grip part is a component of the device, for example arranged on the device. By the handle part, the use of the device for a fitter is facilitated since the fitter can use the upsetting of a corrugated pipe end without storing the device on a base, such as a work table. Through the handle part of the fitter can easily hold the device in an overhead position. Through the handle, it is possible that the fitter can compress right on site at the site and there in well-accessible areas already laid corrugated pipes damming properly.
Das Griffteil bietet sich an, wenn die Vorrichtung ein Schraubgetriebe der vorstehend beschriebenen Art aufweist, so dass der Monteur bereits mit einer geringen aufgebrachten Betätigungskraft hohe Umformkräfte erreicht. Es ist dadurch gewährleistet, dass selbst in schlecht zugänglichen Bereichen der Monteur ein optimales Umformergebnis erzielt.The grip part lends itself to when the device has a helical gear of the type described above, so that the mechanic already applied with a small amount Operating force reaches high forming forces. It is thereby ensured that even in poorly accessible areas of the fitter achieved an optimal forming result.
Es bietet sich an, dass das Griffteil an dem Trägerteil für die Gewindespindel angeordnet ist, insbesondere lösbar daran angeordnet ist. Der Monteur hält dadurch die Vorrichtung in der Nähe der Kraftwirkung. Etwaige Hebelkräfte sind dadurch minimiert und das Aufbringen der Betätigungskraft für die Gewindespindel erleichtert.It is advisable that the handle part is arranged on the support member for the threaded spindle, in particular detachably arranged thereon. The fitter thereby holds the device in the vicinity of the force effect. Any leverage forces are thereby minimized and facilitates the application of the actuating force for the threaded spindle.
Die Vorrichtung kann auch als Tischgerät ausgebildet sein. Die Vorrichtung weist dann beispielsweise einen Grundkörper auf, welcher auf einen Tisch, insbesondere Arbeitstisch, auflegbar oder aufstellbar ist. Die Halteeinrichtung, insbesondere das Trägerteil für den Werkstückhalter, kann fest oder lösbar an dem Grundkörper angebunden sein. Das Trägerteil ist beispielsweise in der Weise ausgerichtet, dass im gehaltenen Zustand eines Wellrohres dessen Längsachse im Wesentlichen parallel zu der Tischfläche liegt, zumindest im Bereich der Halteeinrichtung. Bevorzugt ist in diesem Fall die Richtung der Verschiebebewegung ebenfalls im Wesentlichen parallel zu der Tischfläche.The device can also be designed as a tabletop device. The device then has, for example, a base body which can be placed or set up on a table, in particular a work table. The holding device, in particular the carrier part for the workpiece holder, can be firmly or detachably connected to the base body. The carrier part is aligned for example in such a way that in the held state of a corrugated tube whose longitudinal axis is substantially parallel to the table surface, at least in the region of the holding device. Preferably, in this case, the direction of the sliding movement is also substantially parallel to the table surface.
Die Vorrichtung kann auch ein Vorsatzstauchgerät sein. Bei einem solchen Vorsatzstauchgerät kann die Halteeinrichtung oder die gesamte Vorrichtung einen austauschbaren Kopf bilden, welcher beispielsweise als Vorsatz an eine elektrische Antriebseinheit oder elektrische Betätigungseinheit montierbar ist.The device may also be a Vorsauchauchauchgerät. In such an attachment-type diving apparatus, the holding device or the entire device can form a replaceable head, which can be mounted, for example, as an attachment to an electric drive unit or electrical actuation unit.
Die Erfindung ist besonders zum Stauchen von gewellten Metallrohren, beispielsweise Wellrohren aus Edelstahl, geeignet. Unter Wellrohren sind im Zuge der Erfindung auch Wellschläuche zu verstehen. Den gewellten Rohren ist gemeinsam, dass sie in Richtung ihrer Längsachse einen wellenförmig wechselnden Durchmesser aufweisen. Derartige von der Vorrichtung zu bearbeitende parallel gewellte Rohre können in der Automobilindustrie, dem Maschinen- und/oder Anlagenbau sowie der Medizintechnik eingesetzt werden.The invention is particularly suitable for compressing corrugated metal pipes, such as corrugated pipes made of stainless steel. Under corrugated pipes are to be understood in the invention and corrugated hoses. The corrugated tubes have in common that they have a wave-shaped changing diameter in the direction of their longitudinal axis. Such parallel corrugated tubes to be machined by the device can be used in the automotive industry, mechanical and / or plant engineering and medical technology.
Weiterhin umfasst die Erfindung einen Werkstückhalter gemäß dem Anspruch 13.Furthermore, the invention comprises a workpiece holder according to
Darüber hinaus umfasst die Erfindung ein Verfahren zum Montieren des Werkstückhalters einer Vorrichtung der Erfindung mit den Schritten des Anspruchs 14. Bei dem Verfahren wird zuerst der Werkstückhalter an einem zu bearbeitenden Wellrohr angebracht und anschließend wird der Werkstückhalter, insbesondere zusammen mit dem Wellrohr, in Richtung der Verschiebewegung des Drückteils bewegt, um den Werkstückhalter in eine Befestigungsposition an der Halteeinrichtung zu bringen.In addition, the invention comprises a method for mounting the workpiece holder of a device of the invention with the steps of
Dadurch ist die Handhabung der Vorrichtung für den Monteur erleichtert, da er mit ein und dergleichen Vorrichtung Wellrohre unterschiedlicher Abmessung in einfacher Weise bearbeiten kann. Dazu braucht der Monteur lediglich den für das jeweilige Wellrohr passenden Werkstückhalter auszuwählen und an der Vorrichtung zu montieren. Durch die Montage des Werkstückhalters in Richtung der Verschiebebewegung des Drückteiles ist der Austausch des Werkstückhalters einfach zu handhaben. Dazu braucht der Werkstückhalter beispielsweise lediglich von vorne bzw. unten an die Halteeinrichtung hingeführt werden, beispielsweise entlang der Längsachse des Wellrohres, wie es beispielsweise in der Halteeinrichtung später zu liegen kommt.As a result, the handling of the device for the fitter is facilitated because he can work with one and the like device corrugated tubes of different dimensions in a simple manner. For this purpose, the installer only needs to select the appropriate for each corrugated tube workpiece holder and to mount on the device. By mounting the workpiece holder in the direction of the sliding movement of the pressing member, the replacement of the workpiece holder is easy to handle. For this purpose, the workpiece holder needs, for example are guided only from the front or bottom of the holding device, for example, along the longitudinal axis of the corrugated tube, as it comes to rest later, for example in the holding device.

It may also be a manual or hand-operated drive. For example, the
Zwischen der Koppelstelle 26 und dem Trägerteil 9 kann, anschließend an die Koppelstelle 26, insbesondere anliegend an die Koppelstelle 26, ein Anschlagselement 27 angeordnet sein, welches in seiner axialen Position an der Gewindespindel 6 und/oder der Koppelstelle 26 festgehalten ist und als Anschlag für ein an der Koppelstelle 26 angreifendes Antriebswerkzeug dient. Das Anschlagselement 27 kann in Art eines Scheibenelementes ausgebildet sein, welches bevorzugt einen größeren Durchmesser als die Koppelstelle 26 aufweist. Sofern die Koppelstelle 26 ein Schraubenkopf ist, wird ein Durchrutschen eines daran angreifenden Schraubenschlüsselkopfes in axialer Richtung vermieden.Between the

Dazu kann an dem Drückteil 3 eine Aufnahme 32 ausgebildet sein, in welche die Gewindespindel 6 mit ihrem Ende 7 eingesteckt ist. Zur axialen Sicherung der Verbindung zwischen dem Drückteil 3 und der Gewindespindel 6 ist bevorzugt an der Gewindespindel 6 eine vorzugsweise umlaufende Nut 33 ausgebildet, in welche ein in die Aufnahme 32 eingeführtes oder durchgeführtes Stiftelement oder eine Madenschraube ragt.Preferably, the pressing

Die Trägerteile 9 und 17 bilden zusammen mit den Zwischenelementen 34 einen Grundkörper, wobei das Drückteil 3 vollständig oder teilweise mittels eines Gehäuseteiles überdeckt sein kann. Die Trägerteile 9 und 17 sind bevorzugt jeweils im Wesentlichen plattenförmig ausgebildet und zueinander im Wesentlichen parallel angeordnet.The
Die Durchgangsöffnung 18 ist koaxial bezüglich der Drehachse 5 angeordnet, so dass der Werkstückhalter 15 in Richtung der Verschiebebewegung des Drückteils 3 bzw. in Richtung der Drehachse 5 in die Durchgangsöffnung 18 einführbar ist und in eine Befestigungsposition an dem Trägerteil 17 in axialer Richtung bringbar ist.The

Der Werkstückhalter 15 hat wenigstens einen, vorzugsweise mehrere seitlich nach außen wegstehende Vorsprünge 16, welche mit jeweils einer korrespondierenden Vertiefung 19 am Innenumfang der Durchgangsöffnung 18 korrespondieren. Dadurch kann der Werkstückhalter 15 trotz seiner Vorsprünge 16 in die Durchgangsöffnung 18 eingeschoben werden. Die Vorsprünge 16 und die Vertiefungen 19 bilden einen Teil eines Bajonettverschlusses, durch welchen eine Arretierung des Werkstückhalters 15 gegenüber dem Trägerteil 17 erreicht werden kann, wenn der Werkstückhalter 15 in die Befestigungsposition gebracht ist, in welche er sich in axialer Richtung in seiner Endlage befindet. Durch Verdrehen des Werkstückhalters 15 gegenüber dem Trägerteil 17 um einen vorgegebenen Drehwinkel gelangen die Vorsprünge 16 mit einer Stirnseite gegen die Berandung der Durchgangsöffnung 18 in Anlage, so dass ein Herausziehen des Werkstückhalters 15 aus der Durchgangsöffnung 18 verhindert ist.The

Die Vorrichtung 1 ermöglicht somit folgende Vorgehensweise beim Stauchen eines freien Endes eines Wellrohres: Es wird der Werkstückhalter 15 im Bereich des zu stauchenden Endes eines Wellrohres angebracht. Bevorzugt werden die Teile 21 und 22 des Werkstückhalters 15 an den Außenumfang des Wellrohres angelegt und durch Magnetkraft gegeneinander gehalten. Der Werkstückhalter 15 wird nun zusammen mit dem aufgenommenen Wellrohr mit seinem zu stauchenden Ende voran in die Durchgangsöffnung 18 eingeführt und der Werkstückhalter 15 in die Befestigungsposition gebracht. Durch Verdrehen des Werkstückhalters relativ gegenüber dem Trägerteil 17 wird der Werkstückhalter 15 in seiner axialen Lage arretiert.The
Anschließend wird die Gewindespindel 6 mittels eines an die Koppelstelle 26 angelegten Werkzeuges so lange in Richtung gegen das zu stauchende Ende des Wellrohres verschoben, bis das Drückteil 3 in Anlage gegen das Ende gelangt. Durch Weiterdrehen der Gewindespindel 6 wird durch das Drückteil 3 eine Umformkraft auf das zu stauchende Ende des Wellrohres aufgebracht und so lange erhöht, bis es zu der angestrebten Umformung bzw. Stauchung der aus der Halteeinrichtung 2 herausstehenden Wellen des Wellrohres kommt.Subsequently, the threaded
