- the three pressing jaws 40 to 42 are perfectly aligned with one another.
- the depressions 68, 69 which taper in the plugging direction, together with the projections 70, 71 which likewise taper in the plugging direction, ensure that the engagement between the pressing jaws 40, 41 and 40, 42 is also ensured when the pressing jaws 40 to 42 are not exactly should be aligned with each other. Since the pressing jaws 41, 42 are spaced from the pressing jaw carrier 2, it does not contribute to the guidance of the pressing jaws 41, 42, but instead the projections 70, 71 in cooperation with the depressions 68, 69. The pressing jaws 40 to 42 are thus moved relative to one another they abut one another with their end faces, so that the pressing contours 43 to 45 form a closed surface. The workpiece is radially compressed over its entire circumference, wherein a burr formation on the workpiece is reliably prevented.
- the axes 5, 6, with which the pressing jaw carrier 3, 4 are hinged to the pressing jaw carrier 2, are designed so that when breaking these axes, the pressing ring parts can not be separated from each other. This is achieved in that the axles 5, 6 are provided with a catching device which holds the two tool parts connected to one another by the axles 5 or 6 in such a way that there is no danger of accident or injury to the operator.
- Fig. 5 to 8 the one axis 5 is explained in more detail.
- the other axis 6 is the same. These axes can be used not only in a press ring, as described in the embodiment, but also in other tools, in which two tool parts are pivotally connected together by an axis.
- the axis 5 has a hollow pin 72, on the outside of which at least one predetermined breaking point 73 is provided.
- the hollow bolt 72 has two predetermined breaking points 73 spaced apart from one another. They are each formed by an annular notch on the circumference of the hollow bolt 72.
- the hollow pin 72 is penetrated by a connecting element 74 which connects two covers 76, 79 with each other.
- the connecting element 74 is advantageously a screw, but may also be a rivet, a bolt, a split pin, a pin and the like.
- the connecting element 74 will be described in its construction as a screw.
- the screw 74 is screwed with its free end into a threaded hole 75 in the cover 76.
- the screw head 77 is sunk in a recess 78 in the other lid 79.
- the two covers 76, 79 are held.
- the screw 74 is in the area between the two covers 76, 79 surrounded by a catching device, which is preferably formed by a hose 80 which consists of a tear or shear-resistant material.
- the hose 80 is advantageously against the inner wall of the hollow bolt 72 and surrounds the screw 74 at a distance.
- the hose 80 is advantageously a metal fabric hose, but may also consist of correspondingly tear / shear-resistant plastic or, for example, a textile fabric.
- a solid plastic bolt can be used, are embedded in the long glass fibers.
- the catching device ensures that the tool parts connected to one another with the axle 5 can not be released from one another in the event of a breakage of the axle.
- the screw 74 holds the tool parts connected to one another by the axis 5, in the exemplary embodiment the pressing jaw supports 2 and 3, together.
- the tool parts 2, 3 interconnected by the axis 5 only move relatively little relative to one another.
- the craftsman working with the tool, in the exemplary embodiment with the press ring 1 will often not notice the breakage of the hollow bolt 72 and continue to work with the press ring 1.
- the screw 74 can not absorb the forces occurring during the subsequent pressing process and breaks. As it turned out Fig. 9 results, then the tool parts 2, 3 are shifted by a greater distance from each other.
- Fig. 9 is shown schematically how the tube material is drawn in between these side surfaces.
- the clamping force generated by the retracted tube material is so large that the two pressing jaw carrier 2, 3 do not separate from each other. Since the offset of the two die carrier 2, 3 is clearly visible due to the large displacement path, the worker working with the press ring 1 reliably detects the broken axis 5.
- the tube 80 is preferably made of metal fabric which has a high tear / shear strength, it is ensured that the tube 80 is not severed, but reliably fulfills its clamping effect.
- the metal fabric hose is a low-cost component that can also be very easily installed in the press ring 1. After a break, the axle 5 can be easily removed and replaced by a new axle.
- the tube 80 may be made of any material that has a corresponding tear / shear strength.
- the hose 80 has a wall thickness such that, in the event of a break, the hose is partially drawn between the two press-jaw carriers 2, 3 in the manner described.
- the axis 6 of the pressing ring 1 is formed in the same way, so that even with a fracture of the axis 6 prevents the pressing jaw carrier 2, 4 from each other. Also in this case, a part of the tube 80 is pulled between the abutting surfaces of the pressing jaw carrier 2, 4 and jammed there. The resulting frictional force is so great that the two pressing jaw carriers 2, 4 can not be released from each other.
- the predetermined breaking points 73 of the hollow bolt 72 are as Fig. 4 shows, in the amount of adjacent side surfaces 15, 16; 17, 18 provided the corresponding pressing jaw carrier. As a result, the break occurs at a defined point of the hollow bolt 72. Since these predetermined breaking points 73 in height of the adjacent side surfaces 15, 16; 17, 18 are provided, the tube 80 is reliably pulled in the described case of failure between these adjacent side surfaces when the die holders 2, 3 and 2, 4 move relative to each other due to the axis break.
- the cheek plates are hinged together.
- the hinge connection is the same design as the described and illustrated embodiment.

Abstract
Description
Die Erfindung betrifft ein Presswerkzeug nach dem Oberbegriff des Anspruches 1 sowie ein Werkzeug mit wenigstens zwei relativ zueinander bewegbaren Werkzeugteilen nach dem Oberbegriff des Anspruches 12.The invention relates to a pressing tool according to the preamble of
Es sind Werkzeuge, vorzugsweise Pressringe oder Presswerkzeuge, bekannt, die relativ zueinander bewegbare Werkzeugteile, insbesondere Pressbackenträger, aufweisen. Die Werkzeugteile sind durch eine Gelenkverbindung schwenkbar miteinander verbunden. Sie weist einen die Werkzeugteile durchsetzenden, massiv ausgebildeten Bolzen auf.There are tools, preferably compression rings or pressing tools, known, which have relatively movable tool parts, in particular pressing jaw carrier having. The tool parts are pivotally connected together by a hinge connection. It has a tool parts passing through, solidly formed bolts.
Ist das Werkzeug als Pressring ausgebildet, dann werden die die Werkzeugteile bildenden Pressbacken um ein radial zu verpressendes Werkstück gelegt. Die Pressbacken haben zunächst Abstand voneinander. Beim Pressvorgang nähern die Pressbacken einander an, bis sie mit ihren Stirnseiten aneinander liegen und einen geschlossenen Pressbackenring bilden. Wenigstens zwei der Pressbacken sind hierbei in Umfangsrichtung relativ zu den Pressbackenträgern verschiebbar und an einem der Pressbackenträger geführt. Dadurch soll gewährleistet sein, dass die Pressbacken zuverlässig in die geschlossene Form verstellt werden, in der sie den geschlossenen Pressbackenring bilden. Die Führung der Pressbacken am Pressbackenträger und deren Verschiebbarkeit längs des zugehörigen Pressbackenträgers bedingt eine genaue und damit aufwändige Herstellung des entsprechenden Werkzeuges.If the tool is designed as a press ring, then the pressing jaws which form the tool parts are placed around a workpiece to be pressed radially. The press jaws initially have a distance from each other. During the pressing process, the pressing jaws approach each other until they lie against one another with their end faces and form a closed pressing jaw ring. At least two of the pressing jaws are in this case displaceable in the circumferential direction relative to the pressing jaw carriers and guided on one of the pressing jaw carriers. This is to ensure that the pressing jaws are reliably adjusted in the closed mold in which they form the closed pressing jaw ring. The leadership of the pressing jaws on the pressing jaw carrier and their displaceability along the associated pressing jaw carrier requires an accurate and therefore complex production of the corresponding tool.
Insbesondere bei Presswerkzeugen werden hohe Kräfte aufgewandt, um eine Radialverpressung der Werkstücke zu erreichen. Diese hohe Belastung kann dazu führen, dass der Bolzen, mit dem die Werkzeugteile gelenkig verbunden sind, z.B. wegen Materialermüdung bricht. Dann lösen sich die Werkzeugteile voneinander, wobei eine nicht unerhebliche Verletzungsgefahr für die Bedienungsperson des Werkzeuges besteht.In particular, in pressing tools high forces are used to achieve a radial compression of the workpieces. This high load can cause the bolt to which the tool parts are hinged, e.g. due to material fatigue breaks. Then the tool parts separate from each other, with a significant risk of injury to the operator of the tool.

Im Übergangsbereich sind die Achsen 55 bzw. 56 vorgesehen. Die Außenseiten 57, 58; 59, 60 gehen über einen in Ansicht teilkreisförmigen Abschnitt 61, 62 ineinander über. In den Innenseiten 63, 64 der Pressbackenträger 3, 4 ist eine Vertiefung 65, 66 vorgesehen, deren Boden gleichen Krümmungsradius wie die Außenseitenabschnitte 61, 62 der Pressbacken 41, 42 haben. Sie liegen mit diesen Außenseitenabschnitten 61, 62 flächig am Boden der Vertiefungen 65, 66 an. Die Krümmungsachse der Außenseitenabschnitte 61, 62 sowie des Bodens der Vertiefungen 65, 66 wird durch die Längsmittellinie der Achsen 55, 56 gebildet.The
Wie
Die Innenseite 67 des Pressbackenträgers 2 ist so weit zurückgesetzt, dass die Pressbacken 41, 42 Abstand von der Innenseite 67 haben. Auch von den Innenseiten 63, 64 der Pressbackenträger 3, 4 haben die Pressbacken 41, 42 Abstand, der sich etwa vom Bereich der Schwenkachsen 55, 46 aus in Richtung auf die freien Enden 26, 27 der Pressbackenträger 3, 4 vergrößert.The inner side 67 of the
Die Pressbacken 40 bis 42 sind so ausgebildet, dass sie seitlich nicht über die Pressbackenträger 2 bis 4 vorstehen.The
Die beiden Schenkel 51, 52 der Pressbacke 40 sind an ihrer Stirnseite mittig mit jeweils einer Vertiefung 68, 69 versehen, deren Breite vorteilhaft in Richtung auf das freie Ende der Schenkel 51, 52 zunimmt. An den freien, der Pressbacke 40 zugewandten Enden der Pressbacken 41, 42 ist mittig jeweils ein Vorsprung 70, 71 vorgesehen, der kongruent zu den Vertiefungen 68, 69 ausgebildet ist.The two
Um die Handhabung des Pressringes 1 zu erleichtern, sind die Pressbackenträger 3, 4 vorteilhaft nach innen federbelastet, so dass die Pressbacken 40 bis 42 bei eingelegtem, noch nicht verpresstem Werkstück ihre in den
Dadurch lässt sich die (nicht dargestellte) Zwischenzange problemlos an den Pressring 1 mit dem eingelegten Werkstück anschließen. Die Zwischenzange hat zwei zweiarmige Hebel, die zwischen zwei Laschen liegen, die gleich ausgebildet sind. Die Hebel und die Laschen werden durch jeweils eine Achse miteinander verbunden. Die beiden Hebel sind vorteilhaft so gegeneinander federbelastet, dass die an den Pressring 1 anzuschließenden Arme der Hebel entgegengesetzt zueinander nach außen geschwenkt werden, während die andere Arme in Richtung zueinander geschwenkt werden. Die einen Arme haben jeweils einen Eingriffsteil, der in die Aufnahmen 32, 33 der Pressbackenträger 3, 4 eingreift.As a result, the intermediate pliers (not shown) can be easily connected to the
Die anderen Arme der Hebel der Zwischenzange werden mit Hilfe von Rollen, die an einem Ausfahrstößel eines Antriebes vorgesehen sind, auseinandergedrückt. Dadurch werden die mit dem Pressring 1 verbundenen Arme in Richtung gegeneinander geschwenkt und auf diese Weise der Pressring 1 zusammengezogen. Die Pressbackenträger 3, 4 nehmen hierbei die Pressbacken 41, 42 mit, die bei der Schwenkbewegung der Pressbackenträger 3, 4 relativ zu ihnen geschwenkt werden. Die Pressbacken 41, 42 nähern sich dabei der Pressbacke 40. Die Vorsprünge 70, 71 der Pressbacken 41, 42 gelangen in die Vertiefungen 68, 69 der Pressbacke 40. Infolge dieses Eingriffes werden die drei Pressbacken 40 bis 42 einwandfrei gegeneinander ausgerichtet. Die in Steckrichtung sich verjüngenden Vertiefungen 68, 69 sorgen zusammen mit den in Steckrichtung sich ebenfalls verjüngenden Vorsprüngen 70, 71 dafür, dass der Eingriff zwischen den Pressbacken 40, 41 und 40, 42 auch dann gewährleistet ist, wenn die Pressbacken 40 bis 42 nicht exakt zueinander ausgerichtet sein sollten. Da die Pressbacken 41, 42 Abstand vom Pressbackenträger 2 haben, trägt er zur Führung der Pressbacken 41, 42 nicht bei, sondern die Vorsprünge 70, 71 im Zusammenwirken mit den Vertiefungen 68, 69. Die Pressbacken 40 bis 42 werden so gegeneinander bewegt, bis sie mit ihren Stirnseiten aneinanderliegen, so dass die Presskonturen 43 bis 45 eine geschlossene Fläche bilden. Das Werkstück wird über seinen gesamten Umfang radial verpresst, wobei eine Gratbildung am Werkstück zuverlässig vermieden wird.The other arms of the intermediate tongs levers are forced apart by means of rollers provided on an extension tappet of a drive. As a result, the arms connected to the
Ist der Pressvorgang abgeschlossen, wird der Stößel des Antriebes zurückgefahren, so dass die entsprechenden Arme der Zwischenzange wieder in Richtung zueinander geschwenkt werden. Dies hat zur Folge, dass die mit dem Pressring 1 in Eingriff befindlichen anderen Arme der Zwischenzange die Pressbackenträger 3, 4 zurück in die in den
Die Achsen 5, 6, mit denen die Pressbackenträger 3, 4 an den Pressbackenträger 2 angelenkt sind, sind so ausgebildet, dass bei einem Bruch dieser Achsen die Pressringteile sich nicht voneinander lösen können. Dies wird dadurch erreicht, dass die Achsen 5, 6 mit einer Fangeinrichtung versehen sind, die die beiden durch die Achsen 5 bzw. 6 miteinander verbundenen Werkzeugteile so zusammenhält, dass eine Unfall- bzw. Verletzungsgefahr für die Bedienungsperson nicht besteht.The
Anhand der
Die Achse 5 hat einen Hohlbolzen 72, an dessen Außenseite wenigstens eine Sollbruchstelle 73 vorgesehen ist. Im Ausführungsbeispiel hat der Hohlbolzen 72 zwei mit Abstand voneinander liegende Sollbruchstellen 73. Sie werden jeweils durch eine ringförmige Einkerbung am Umfang des Hohlbolzens 72 gebildet.The
Der Hohlbolzen 72 wird von einem Verbindungselement 74 durchsetzt, das zwei Deckel 76, 79 miteinander verbindet. Das Verbindungselement 74 ist vorteilhaft eine Schraube, kann aber auch ein Niet, ein Bolzen, ein Splint, ein Stift und dgl. sein. Im Folgenden wird das Verbindungselement 74 in seiner Ausbildung als Schraube beschrieben. Die Schraube 74 wird mit ihrem freien Ende in eine Gewindebohrung 75 im Deckel 76 geschraubt. Der Schraubenkopf 77 liegt versenkt in einer Vertiefung 78 in dem weiteren Deckel 79. Über die Schraube 74 werden die beiden Deckel 76, 79 gehalten.The
Die Schraube 74 ist im Bereich zwischen den beiden Deckeln 76, 79 von einer Fangeinrichtung umgeben, die in bevorzugter Weise durch einen Schlauch 80 gebildet ist, der aus einem reiß- bzw. scherfesten Material besteht. Der Schlauch 80 liegt vorteilhaft an der Innenwand des Hohlbolzens 72 an und umgibt mit Abstand die Schraube 74. Der Schlauch 80 ist vorteilhaft ein Metallgewebeschlauch, kann aber auch aus entsprechend reiß/ scherfestem Kunststoff oder beispielsweise aus einem Textilgewebe bestehen. Auch kann an Stelle der Schraube 74 mit dem Schlauch 80 ein massiver Kunststoffbolzen verwendet werden, in den lange Glasfasern eingebettet sind.The
Die Fangeinrichtung sorgt dafür, dass die mit der Achse 5 miteinander verbundenen Werkzeugteile im Falle eines Bruches der Achse nicht voneinander gelöst werden können.The catching device ensures that the tool parts connected to one another with the
Bricht der Hohlbolzen 72 an einer der Sollbruchstellen 73, hält die Schraube 74 die durch die Achse 5 miteinander verbundenen Werkzeugteile, im Ausführungsbeispiel die Pressbackenträger 2 und 3, zusammen. Bei einem Bruch des Hohlbolzens 72 verschieben sich die durch die Achse 5 miteinander verbundenen Werkzeugteile 2, 3 nur relativ wenig zueinander. Der mit dem Werkzeug, im Ausführungsbeispiel mit dem Pressring 1, arbeitende Handwerker wird häufig den Bruch des Hohlbolzens 72 nicht bemerken und mit dem Pressring 1 weiterarbeiten. Die Schraube 74 kann jedoch die beim nachfolgenden Pressvorgang auftretenden Kräfte nicht aufnehmen und bricht. Wie sich aus
Selbst wenn er dennoch einen weiteren Pressvorgang ausführen möchte, kann eine Radialverpressung des Werkstückes nicht mehr durchgeführt werden. Aufgrund des großen Verschiebeweges zwischen den beiden Pressbackenträgern 2, 3 sind die an ihnen gelagerten Pressbacken 40 bis 42 so weit voneinander entfernt, dass eine Radialverpressung nicht mehr durchgeführt werden kann.Even if he still wants to perform a further pressing process, a radial compression of the workpiece can not be performed. Due to the large displacement path between the two
Da der Schlauch 80 in bevorzugter Weise aus Metallgewebe besteht, das eine hohe Reiß/Scherfestigkeit hat, ist gewährleistet, dass der Schlauch 80 nicht durchgetrennt wird, sondern seine Klemmwirkung zuverlässig erfüllt. Der Metallgewebeschlauch ist ein kostengünstiges Bauteil, das sich zudem sehr einfach in den Pressring 1 einbauen lässt. Nach einem Bruch lässt sich die Achse 5 problemlos ausbauen und durch eine neue Achse ersetzen.Since the
Der Schlauch 80 kann aus jedem Material bestehen, das eine entsprechende Reiß/Scherfestigkeit aufweist. Der Schlauch 80 hat eine solche Wandstärke, dass im Bruchfall der Schlauch teilweise zwischen die beiden Pressbackenträger 2, 3 in der beschriebenen Weise gezogen wird.The
Die Achse 6 des Pressringes 1 ist in gleicher Weise ausgebildet, so dass auch bei einem Bruch der Achse 6 verhindert wird, dass sich die Pressbackenträger 2, 4 voneinander lösen. Auch in diesem Falle wird ein Teil des Schlauches 80 zwischen die aneinanderliegenden Flächen der Pressbackenträger 2, 4 gezogen und dort verklemmt. Die entstehende Reibkraft ist so groß, dass die beiden Pressbackenträger 2, 4 nicht voneinander gelöst werden können.The axis 6 of the
Die beschriebene Gelenkverbindung ist beispielhaft an einem Pressring 1 beschrieben worden. Solche Gelenkverbindungen können aber überall dort eingesetzt werden, wo zwei Teile mit Hilfe der Gelenkverbindung schwenkbar miteinander verbunden werden.The articulated connection described has been described by way of example on a
Die Sollbruchstellen 73 des Hohlbolzens 72 sind, wie
Hat das Presswerkzeug nur zwei Pressbacken, dann sind zusätzliche Pressbackenträger nicht erforderlich. In diesem Fall sind die Pressbackenträger gelenkig miteinander verbunden. Die Gelenkverbindung ist gleich ausgebildet wie das beschriebene und dargestellte Ausführungsbeispiel.If the pressing tool has only two pressing jaws, then additional pressing jaw carriers are not required. In this case, the cheek plates are hinged together. The hinge connection is the same design as the described and illustrated embodiment.
