Description

Die vorliegende Erfindung betrifft eine Radialpresse mit einer Grundstruktur, einem darin aufgenommenen Presswerkzeug und einer Antriebseinheit, wobei das Presswerkzeug mehrere um eine Pressenachse herum angeordnete Grundbacken umfasst, welche mittels der Antriebseinheit synchron radial auf die Pressenachse zu bzw. von dieser weg bewegbar sind und an denen jeweils ein im Wesentlichen keilförmiger Pressbackenkopf auswechselbar anbringbar ist, und wobei weiterhin in einem zugeordneten Magazin eine Mehrzahl von auf unterschiedliche Pressdurchmesser abgestimmten Pressbackenkopfsätzen bevorratet ist.The present invention relates to a radial press with a basic structure, a press tool accommodated therein and a drive unit, the press tool comprising several base jaws arranged around a press axis, which can be moved radially towards and away from the press axis synchronously by means of the drive unit and on which a substantially wedge-shaped press jaw head can be attached in an exchangeable manner, and a plurality of press jaw head sets matched to different press diameters is also stored in an assigned magazine.

Radialpressen der vorstehenden Art, wie sie beispielsweise der Herstellung einer festen Verbindung zwischen einem Hydraulikschlauch und einer endseitig an diesem angeordneten Anschlussarmatur dienen, sind in diversen Ausführungen bekannt, insbesondere aus dem Produktprogramm der Uniflex Hydraulik GmbH, Karben (Deutschland). Dabei ist typischerweise das Magazin, in welchem die auf unterschiedliche Pressdurchmesser abgestimmten Pressbackenkopfsätze bevorratet sind, in dem Rahmen der Radialpresse untergebracht, so wie dies beispielsweise auch der US 6257042 B1 entnehmbar ist. In der US 4250607 A wird alternativ ein Revolvermagazin vorgeschlagen.Radial presses of the above type, such as those used, for example, to establish a fixed connection between a hydraulic hose and a connection fitting arranged at the end, are known in various designs, in particular from the product range of Uniflex Hydraulik GmbH, Karben (Germany). The magazine, in which the press jaw head sets matched to different press diameters are stored, is typically accommodated in the frame of the radial press, as is also the case, for example US 6257042 B1 is removable. In the US 4250607 A a revolver magazine is suggested as an alternative.

Im Hinblick auf gute Ergebnisse der Radialpressung weisen die Presswerkzeuge typischerweise acht Grundbacken auf und sind die Pressbackenkopfsätze vergleichsweise eng gestaffelt. D.h., es sind an der Radialpresse entsprechend viele in dem Magazin zu bevorratende Pressbackenkopfsätze mit (typischerweise acht) sich untereinander jeweils nur geringfügig unterscheidenden Pressbackenköpfen vorhanden.With regard to good results of the radial pressing, the pressing tools typically have eight base jaws and the pressing jaw head sets are comparatively narrow staggered. In other words, there are correspondingly many sets of press jaw heads to be stored in the magazine with (typically eight) press jaw heads that differ from one another only slightly.

Zum Wechsel der vollständigen Pressbackenkopfsätze, um die Radialpresse von einem Pressdurchmesser auf einen anderen umzurüsten, dienen üblicherweise Spezialwerkzeuge, beispielsweise gemäß der DE 20109212 U1 oder der EP 1610915 B1 . Allerdings ist oft eine Einzelentnahme bzw. Einzelmontage der Pressbackenköpfe unvermeidlich.To change the complete press jaw head sets in order to convert the radial press from one press diameter to another, special tools are usually used, for example according to FIG DE 20109212 U1 or the EP 1610915 B1 . However, individual removal or individual assembly of the press jaw heads is often unavoidable.

Dies führt zu der potentiellen Gefahr, dass sehr ähnliche Pressbackenköpfe versehentlich vertauscht werden, indem beispielsweise ein acht Pressbackenköpfe umfassender Pressbackenkopfsatz einen Pressbackenkopf mit Unter- oder Übermaß enthält. Da sich die Pressbackenköpfe kaum unterscheiden, bleibt dies häufig unbemerkt. Die mit einem solchen (vermeintlichen) "Pressbackenkopfsatz" ausgeführte Pressung aber ist fehlerhaft und erfüllt nicht die an sie gestellten Anforderungen. Das kann sogar zu solchen Fehlpressungen führen, die, wenn die betreffenden Werkstücke zum Einsatz kommen, wegen eines Ausfalls bzw. Versagens des betreffenden Werkstücks eine Gefahr für die Umgebung darstellen.This leads to the potential danger that very similar press jaw heads are accidentally mixed up, for example in that a press jaw head set comprising eight press jaw heads contains a press jaw head with undersized or oversized dimensions. Since the press jaw heads hardly differ, this often goes unnoticed. The pressing carried out with such a (supposed) "press jaw head set", however, is faulty and does not meet the requirements placed on it. This can even lead to such incorrect crimps that, when the workpieces in question are used, represent a danger to the environment due to a failure or failure of the workpiece in question.

Es ist vorgeschlagen worden (vgl. DE 20017791 U1 ), die (insbesondere acht) Pressbackenköpfe eines Pressbackenkopfsatzes untereinander so zu verbinden, dass sie einen untrennbaren Verband bilden. Auf diese Weise lässt sich (theoretisch) das vorstehend thematisierte versehentliche Vertauschen von Pressbackenköpfen vermeiden. Allerdings ist, wie weiter oben dargelegt, oft das Abnehmen einzelner Pressbackenköpfe von den Grundbacken bzw. die Montage einzelner Pressbackenköpfe an den Grundbacken unvermeidlich, so dass das Zusammenfügen der Pressbackenköpfe zu einem Verband nicht uneingeschränkt zielführend ist.It has been suggested (cf. DE 20017791 U1 ) to connect the (in particular eight) press jaw heads of a press jaw head set with one another in such a way that they form an inseparable association. In this way (theoretically) the above can be addressed Avoid accidentally interchanging press jaw heads. However, as explained above, the removal of individual press jaw heads from the base jaws or the assembly of individual press jaw heads on the base jaws is often unavoidable, so that joining the press jaw heads to form an association is not entirely effective.

Die vorliegende Erfindung ist darauf gerichtet, eine gattungsgemäße Radialpresse bereitzustellen, die im Hinblick auf die vorstehend erörterte Problematik des Standes der Technik verbessert ist.The present invention is aimed at providing a generic radial press which is improved with regard to the problems of the prior art discussed above.

Gelöst wird diese Aufgabenstellung gemäß der vorliegenden Erfindung, indem bei einer Radialpresse der gattungsgemäßen Art die Pressbackenköpfe an mindestens einer axialen Stirnseite unmittelbar angrenzend an beiden Keilflächen zwei Markierungen aufweisen, wobei jeweils die beiden einander gegenüberstehenden Markierungen zweier benachbarter Pressbackenköpfe zueinander fluchten, und wobei weiterhin bei verschiedenen Pressbackenkopfsätzen zueinander unterschiedliche Markierungen vorgesehen sind. Die erfindungsgemäße Radialpresse zeichnet sich somit durch spezifische, an jeweils zumindest einer der Stirnseiten der Pressbackenköpfe vorgesehene Markierungen aus, wobei durch die Anordnung der Markierungen unmittelbar angrenzend an die Keilflächen der Pressbackenköpfe jeweils zwei an einander benachbarten Pressbackenköpfen vorgesehene Markierungen einander fluchtend gegenüberstehen. Dies ermöglicht, dass auf dem Wege einer optischen Kontrolle leicht erfasst wird, ob sämtliche an den Grundbacken montierten Pressbackenköpfe zu demselben Pressbackenkopfsatz gehören oder nicht, wobei das Presswerkzeug für diese optische Kontrolle zweckmäßigerweise in die vollständig geschlossene Stellung gebracht wird, in welcher einander benachbarte Pressbackenköpfe aneinander anliegen.This object is achieved according to the present invention in that, in a radial press of the generic type, the pressing jaw heads have two markings on at least one axial end face immediately adjacent to both wedge surfaces, the two opposing markings of two adjacent pressing jaw heads being aligned with one another, and with different ones Press jaw head sets different markings are provided. The radial press according to the invention is thus characterized by specific markings provided on at least one of the end faces of the press jaw heads, with the arrangement of the markings directly adjacent to the wedge surfaces of the press jaw heads in each case two markings provided on adjacent press jaw heads being aligned opposite one another. This makes it possible, by way of an optical control, to easily detect whether all the press jaw heads mounted on the base jaws belong to the same Press jaw head set belong or not, whereby the press tool for this visual inspection is expediently brought into the completely closed position in which adjacent press jaw heads rest against one another.

In bevorzugter Weiterbildung der vorliegenden Erfindung sind die Markierungen der Pressbackenköpfe jeweils eines Pressbackenkopfsatzes untereinander identisch ausgeführt. Dies gilt namentlich dann, wenn die Einbaubaulage der einzelnen Pressbackenköpfe an den Grundbacken der Radialpresse ohne Bedeutung ist, insbesondere weil sämtliche Pressbackenköpfe des betreffenden Pressbackenkopfsatzes absolut identisch sind. Ist dies indessen nicht der Fall, so können - gemäß einer anderen bevorzugten, weiter unten näher erläuterten Weiterbildung der Erfindung - auch die Markierungen der einzelnen Pressbackenköpfe jeweils eines Pressbackenkopfsatzes untereinander unterschiedlich ausgeführt sein.In a preferred development of the present invention, the markings of the press jaw heads of each press jaw head set are designed to be identical to one another. This applies in particular when the installation position of the individual press jaw heads on the base jaws of the radial press is of no importance, in particular because all the press jaw heads of the relevant press jaw head set are absolutely identical. If, however, this is not the case, then - according to another preferred further development of the invention explained in more detail below - the markings of the individual press jaw heads in each case of a press jaw head set can also be designed differently from one another.

Sind die Markierungen der Pressbackenköpfe jeweils eines Pressbackenkopfsatzes untereinander identisch ausgeführt, so unterscheiden sich die Markierungen der verschiedenen Pressbackenkopfsätze bevorzugt zumindest hinsichtlich ihres Abstands zu der (radial äußeren) Kontaktfläche, an der die Pressbackenköpfe an den Grundbacken anliegen. So fluchten - bei der besagten optischen Kontrolle - die beiden jeweils einander gegenüberstehen Markierungen zweier benachbarter Pressbackenköpfe, sofern die betreffenden zwei Pressbackenköpfe zu demselben Pressbackenkopfsatz gehören. Gehören indessen die betreffenden zwei Pressbackenköpfe zu unterschiedlichen Pressbackenkopfsätzen, so fluchten die beiden einander gegenüberstehen Markierungen nicht, sondern sind (mehr oder weniger stark) radial zueinander versetzt. Ein solcher radialer Versatz der Markierungen benachbarter Pressbackenköpfe wird leicht wahrgenommen, so dass die Anbringung eines falschen Pressbackenkopfes, d.h. eines Pressbackenkopfes mit Unter- oder Übermaß gegenüber den anderen Pressbackenköpfen nicht unerkannt bleibt.If the markings of the press jaw heads of a press jaw head set are identical to one another, the markings of the different press jaw head sets preferably differ at least in terms of their distance from the (radially outer) contact surface on which the press jaw heads rest on the base jaws. Thus, in the case of the said optical inspection, the two markings of two adjacent press jaw heads that are opposite one another are aligned, provided that the two press jaw heads in question belong to the same press jaw head set. If, however, the two press jaw heads in question belong to different press jaw head sets, then the two are aligned with one another are not opposite markings, but are (more or less strongly) offset radially from one another. Such a radial offset of the markings of adjacent press jaw heads is easily perceived, so that the attachment of a wrong press jaw head, ie a press jaw head with undersized or oversized dimensions compared to the other press jaw heads, does not go unnoticed.

In bevorzugter Weiterbildung der vorliegenden Erfindung sind die beiden Markierungen jedes Pressbackenkopfes jeweils Teil einer sich zumindest im Wesentlichen zwischen den beiden Keilflächen erstreckenden linienförmigen Markierung. Besonders bevorzugt erstrecken sich die linienförmigen Markierungen jeweils durchgehend von einer Keilfläche zur anderen, so dass bei einem vollständig geschlossenen Presswerkzeug stirnseitig im Bereich der Pressbackenköpfe eine durchgehende Markierungslinie sichtbar ist. Dies erhöht die Auffälligkeit einer Fehlbestückung der Grundbacken, d.h. der Montage eines nicht zu den anderen Pressbackenköpfen passenden Pressbackenkopfes, und trägt auf diese Weise zu einem besonders geringen Risiko einer unerkannten Fehlbestückung der Radialpresse bei. In dem Falle, dass die Markierungen sämtlicher Pressbackenköpfe eines Pressbackenkopfsatzes identisch übereinstimmen (s.o.), hat die durchgehende Markierungslinie eine in sich geschlossene Gestalt. Sind die einzelnen Markierungslinien der Pressbackenköpfe dabei im Wesentlichen als Kreisbogensegmente ausgeführt, kann die sich ergebende geschlossene Markierungslinie des gesamten Pressbackenkopfsatzes kreisförmig sein. Andere besonders geeignete geschlossene Markierungslinien sind regelmäßige Polygone, beispielsweise Achtecke.In a preferred development of the present invention, the two markings of each press jaw head are each part of a linear marking extending at least substantially between the two wedge surfaces. Particularly preferably, the line-shaped markings each extend continuously from one wedge surface to the other, so that with a completely closed pressing tool, a continuous marking line is visible on the end face in the region of the pressing jaw heads. This increases the conspicuity of incorrectly fitting the base jaws, ie the assembly of a press jaw head that does not match the other press jaw heads, and in this way contributes to a particularly low risk of undetected incorrect fitting of the radial press. In the event that the markings of all the press jaw heads of a press jaw head set coincide identically (see above), the continuous marking line has a self-contained shape. If the individual marking lines of the press jaw heads are essentially designed as circular arc segments, the resulting closed marking line of the entire press jaw head set can be circular. Other particularly suitable closed marking lines are regular polygons, for example octagons.

Alternativ oder additiv zu der weiter oben dargelegten unterschiedlichen Anordnung der Markierungen bzw. Markierungslinien der verschiedenen Pressbackenkopfsätze zumindest hinsichtlich ihres Abstands zu der Kontaktfläche, an der die Pressbackenköpfe an den Grundbacken anliegen, können sich die Markierungslinien insbesondere auch hinsichtlich der Formgebung unterscheiden. So können beispielsweise die Markierungslinien radial nach außen bogenförmig gekrümmt, geradlinig und radial nach innen bogenförmig gekrümmt ausgeführt sein. So fällt ein nicht zu den übrigen Pressbackenköpfen gehörender Pressbackenkopf durch die Formgebung seiner Markierungslinie sofort auf. Dabei wäre es sogar unschädlich, wenn sich bei jedem dritten Pressbackenkopfsatz die Formgebung der Markierungslinie wiederholt; denn in einem solchen Fall würde der fehlbestückte Pressbackenkopf durch seine von den anderen Pressbackenköpfen erheblich abweichende Dimensionierung auffallen.As an alternative or in addition to the different arrangement of the markings or marking lines of the various sets of press jaws set out above, at least in terms of their distance from the contact surface on which the press jaw heads rest on the base jaws, the marking lines can also differ in particular with regard to the shape. For example, the marking lines can be curved radially outwards in an arc shape, straight and curved in an arc shape radially inwards. A press jaw head that does not belong to the other press jaw heads is immediately noticeable due to the shape of its marking line. It would even be harmless if the shape of the marking line was repeated for every third set of press jaw heads; because in such a case the incorrectly equipped press jaw head would attract attention due to its dimensioning which differs significantly from the other press jaw heads.

Gemäß einer anderen bevorzugten Weiterbildung der vorliegenden Erfindung umfassen die linienförmigen Markierungen in die betreffende Stirnfläche des jeweiligen Pressbackenkopfes eingearbeitete rillenförmige Vertiefungen oder aber an der betreffenden Stirnfläche des jeweiligen Pressbackenkopfes angeordnete erhabene Stege. Dies erhöht nicht nur die optische Wahrnehmbarkeit einer möglichen Fehlbestückung. Vielmehr lässt sich eine solche (zusätzlich) auch ertasten. Dies kommt der Zuverlässigkeit der Kontrolle auf eine ordnungsgemäße Bestückung der Radialpresse entgegen.According to another preferred development of the present invention, the line-shaped markings comprise groove-shaped depressions machined into the respective end face of the respective press jaw head or raised webs arranged on the respective end face of the respective press jaw head. This not only increases the visual perceptibility of a possible incorrect assembly. Rather, it can (additionally) also be felt. This helps the reliability of the control of the correct loading of the radial press.

Gemäß einer wiederum anderen bevorzugten Weiterbildung der vorliegenden Erfindung weisen, sofern sämtliche Pressbackenköpfe eines Pressbackenkopfsatzes identisch ausgeführt sind, die Markierungen der einzelnen Pressbackenkopfsätze jeweils im Wesentlichen den gleichen Abstand zur Pressfläche auf. Damit reflektieren die Markierungen unmittelbar den Pressdurchmesser, auf den die einzelnen Pressbackenköpfe abgestimmt sind. Im Hinblick auf eine noch bessere Wahrnehmbarkeit einer Fehlbestückung können allerdings, in alternativer bevorzugter Ausgestaltung, die Markierungen der Pressbackenköpfe für einen größeren Pressdurchmesser einen größeren Abstand zur Pressfläche aufweisen als die Pressbackenköpfe für einen geringeren Pressdurchmesser. Damit wird über den - im Falle einer Fehlbestückung - gewissermaßen übersteigerten Versatz der Markierungen zueinander besonders deutlich, dass einer der Pressbackenköpfe nicht zu den anderen passt.According to yet another preferred development of the present invention, provided that all press jaw heads of a press jaw head set are designed identically, the markings of the individual press jaw head sets each have essentially the same distance from the press surface. The markings thus directly reflect the crimping diameter to which the individual crimping jaw heads are matched. With regard to an even better perceptibility of an incorrect assembly, however, in an alternative preferred embodiment, the markings of the pressing jaw heads for a larger pressing diameter can have a greater distance from the pressing surface than the pressing jaw heads for a smaller pressing diameter. This makes it particularly clear - in the event of a faulty assembly - that the markings are offset to one another, so to speak, that one of the press jaw heads does not match the others.

Ebenfalls im Interesse einer besonders großen Auffälligkeit einer Fehlbestückung können sich die Markierungen der einzelnen Pressbackenkopfsätze farblich voneinander unterscheiden.The color of the markings on the individual press jaw head sets can also differ from one another in terms of color, also in the interest of a particularly high level of conspicuity in the event of a faulty assembly.

Weiter oben wurde bereits dargelegt, dass - gemäß einer bevorzugten Weiterbildung der Erfindung - auch die Markierungen der einzelnen Pressbackenköpfe jeweils eines Pressbackenkopfsatzes untereinander unterschiedlich ausgeführt sein können. Diese Weiterbildung kommt vorteilhafterweise zum Einsatz, wenn die Einbaubaulage der einzelnen Pressbackenköpfe an den Grundbacken der Radialpresse von Bedeutung ist, insbesondere weil die Pressbackenköpfe des betreffenden Pressbackenkopfsatzes nicht absolut identisch sind. Dies gilt beispielsweise, wenn die einzelnen Pressbackenköpfe des betreffenden Pressbackenkopfsatzes einen spezifischen Schliff aufweisen, so dass die Gesamtheit der Pressflächen (bei geschlossener Radialpresse) keinen idealen Kreiszylinder definieren.It has already been explained above that - according to a preferred development of the invention - the markings of the individual press jaw heads in each case of a press jaw head set can also be designed differently from one another. This development is advantageously used when the installation position of the individual press jaw heads on the base jaws of the radial press is important, in particular because the press jaw heads of the relevant press jaw head set are not absolutely identical. This applies, for example, if the individual press jaw heads of the relevant press jaw head set have a specific cut so that the entirety of the press surfaces (when the radial press is closed) does not define an ideal circular cylinder.

Auch in diesem Falle können die beiden Markierungen jedes Pressbackenkopfes jeweils Teil einer sich durchgehend von einer Keilfläche zur anderen erstreckenden linienförmigen Markierung sein, so dass bei einem vollständig geschlossenen Presswerkzeug stirnseitig eine sich über alle Pressbackenköpfe erstreckende Markierungslinie sichtbar ist. Die betreffende - bei vollständig geschlossenem Presswerkzeug sichtbare - durchgehende Markierungslinie kann dabei beispielsweise die Gestalt einer Spirale aufweisen. Eine auffällige Abweichung der Markierung von ihrer Sollgestalt, d.h. einer durchgehenden Markierungslinie, ergibt sich in diesem Falle sowohl im Falle einer Fehlbestückung des Pressbackenkopfsatzes mit einem nicht zu diesem gehörenden Pressbackenkopf, als auch im Falle einer von der vorgegebenen Anordnung der einzelnen Pressbackenköpfe des Pressbackenkopfsatzes zueinander abweichenden Anordnung.In this case, too, the two markings of each press jaw head can each be part of a line-shaped mark extending continuously from one wedge surface to the other, so that a marking line extending over all press jaw heads is visible at the end when the press tool is completely closed. The relevant continuous marking line - visible when the pressing tool is completely closed - can have the shape of a spiral, for example. A conspicuous deviation of the marking from its intended shape, ie a continuous marking line, results in this case both in the case of an incorrect fitting of the press jaw head set with a press jaw head that does not belong to this, as well as in the case of a differing from the predetermined arrangement of the individual press jaw heads of the press jaw head set Arrangement.

Schließlich ist zu erwähnen, dass die Pressbackenköpfe an beiden axialen Stirnseiten unmittelbar angrenzend an beiden Keilflächen - im Sinne der vorliegenden, vorstehend dargelegten Erfindung - zwei Markierungen aufweisen können, wobei an jeder der beiden Stirnseiten jeweils die beiden einander gegenüberstehenden Markierungen zweier benachbarter Pressbackenköpfe zueinander fluchten. Sind die Pressbackenköpfe dabei dergestalt asymmetrisch ausgeführt, so dass sie in zwei unterschiedlichen Einbaulagen an den Grundbacken angebracht werden können, so sind besonders bevorzugt die Markierungen der Pressbackenköpfe jeweils an den beiden Stirnseiten unterschiedlich ausgeführt. Auf diese Weise lässt sich durch optische Kontrolle leicht erfassen, wenn einer der Pressbackenköpfe in einer anderen Einbaulage montiert ist als die anderen Pressbackenköpfe.Finally, it should be mentioned that the press jaw heads can have two markings on both axial end faces immediately adjacent to both wedge surfaces - within the meaning of the present invention set out above - with the two opposing markings of two adjacent press jaw heads on each of the two end faces align with each other. If the press jaw heads are designed asymmetrically so that they can be attached to the base jaws in two different installation positions, the markings of the press jaw heads are particularly preferably designed differently on the two end faces. In this way it can easily be detected by optical control if one of the press jaw heads is mounted in a different installation position than the other press jaw heads.

Nachdem Radialpressen, auf welchen sich die vorliegende Erfindung umsetzen lässt, ihrer Art nach - zumindest den hier maßgeblichen Fachleuten - hinlänglich bekannt sind, beschränkt sich die Veranschaulichung der Ausführungsbeispiele der Erfindung auf den jeweiligen (in den Figuren 1 bis 3 jeweils fehlbestückten) Pressbackenkopfsatz.Since radial presses, on which the present invention can be implemented, are sufficiently known by their type - at least to the relevant experts here - the illustration of the exemplary embodiments of the invention is limited to the respective (in the Figures 1 to 3 each incorrectly equipped) press jaw head set.

In Fig. 1 sind acht um eine Pressenachse 1 herum angeordnete, keilförmige Pressbackenköpfe 2 dargestellt, welche zu ihrer auswechselbaren Anbringung an den acht Grundbacken der jeweiligen Radialpresse jeweils an ihrer - die Kontaktfläche 3 zur zugeordneten Grundbacke bildenden - radialen Außenfläche 4 mit einem Rastzapfen 5 versehen sind. Die Pressbackenköpfe 2 sind dabei in jener Konfiguration dargestellt, welche sie bei maximal geschlossenem Presswerkzeug einnehmen, indem nämlich die jeweils einander gegenüberliegenden Keilflächen 6 zweier benachbarter Pressbackenköpfe aneinander anliegen.In Fig. 1 eight wedge-shaped press jaw heads 2 are shown arranged around a press axis 1, which are provided with a locking pin 5 on their radial outer surface 4, which forms the contact surface 3 to the assigned base jaw, for their interchangeable attachment to the eight base jaws of the respective radial press. The press jaw heads 2 are shown in the configuration that they assume when the press tool is maximally closed, namely in that the respective opposing wedge surfaces 6 of two adjacent press jaw heads bear against one another.

An den gezeigten axialen Stirnflächen 7 weisen die Pressbackenköpfe 2 jeweils unmittelbar angrenzend an die beiden Keilflächen 6 zwei Markierungen 8 auf. Die Markierungen 8 halten dabei einen übereinstimmenden Abstand x zu jener Kante 9 ein, an welcher jeweils die betreffende Keilfläche 6 und die Pressfläche 10 des betreffenden Pressbackenkopfes 2 aneinander stoßen. Auf diese Weise fluchten jeweils die einander gegenüberstehenden Markierungen 8 zweier identisch ausgeführter, zu dem gleichen Pressbackenkopfsatz gehörender Pressbackenköpfe 2. Indessen besteht zwischen den Markierungen 8 zweier Pressbackenköpfe 2, die nicht zu dem gleichen Pressbackenkopfsatz gehören, ein Versatz V. Dieser entspricht Unterschied U im Pressmaßradius, ist aber auffälliger.On the axial end faces 7 shown, the pressing jaw heads 2 each have two markings 8 immediately adjacent to the two wedge surfaces 6. The markings 8 maintain a matching distance x from the edge 9 at which the relevant wedge surface 6 and the pressing surface 10 of the relevant pressing jaw head 2 abut one another. In this way, the opposing markings 8 of two identically designed press jaw heads 2 belonging to the same press jaw head set are aligned V. This corresponds to the difference U in the press size radius, but is more noticeable.

Nach Fig. 2 sind jeweils die beiden an die betreffenden Keilflächen angrenzenden Markierungen 8 jedes Pressbackenkopfes 2 Teil einer sich durchgehend zwischen den beiden Keilflächen 6 erstreckende linienförmigen Markierung 11. Diese Markierungslinie 11 ist als Kreisbogensegment ausgeführt, und zwar konzentrisch zur Pressenachse 1. Für eine besonders große Auffälligkeit einer Fehlbestückung weisen hier die Markierungen 8 (und dementsprechend die Markierungslinien 11) der Pressbackenköpfe 2 für einen größeren Pressdurchmesser einen größeren Abstand a zur Pressfläche 10 auf als die Pressbackenköpfe 2 für einen geringeren Pressdurchmesser. So ist der Versatz V der Markierungslinien 11 zweier benachbarter Pressbackenköpfe 2, welche nicht zu dem gleichen Pressbackenkopfsatz gehören, entsprechend größer und auffälliger als der Unterschied U der Pressflächen 10 zueinander.To Fig. 2 The two markings 8 of each press jaw head 2 adjoining the relevant wedge surfaces are part of a line-shaped marking 11 extending continuously between the two wedge surfaces 6. This marking line 11 is designed as a circular arc segment, concentric to the press axis 1. Here, the markings 8 (and accordingly the marking lines 11) of the press jaw heads 2 for a larger press diameter have a greater distance a from the press surface 10 than the press jaw heads 2 for a smaller press diameter. The offset V of the marking lines 11 of two adjacent press jaw heads 2, which do not belong to the same press jaw head set, is correspondingly larger and more conspicuous than the difference U between the press surfaces 10.

Fig. 3 veranschaulicht die Möglichkeit, dass sich die Markierungslinien 11 der Pressbackenköpfe 2, welche zu unterschiedlichen Pressbackenkopfsätzen gehören, hinsichtlich der Formgebung auffällig voneinander unterscheiden. Fig. 3 illustrates the possibility that the marking lines 11 of the press jaw heads 2, which belong to different press jaw head sets, differ conspicuously from one another in terms of shape.

Bei der in Fig. 4 veranschaulichten Ausführungsform sind die beiden stirnseitig an allen Pressbackenköpfen 2 vorgesehenen Markierungen 8 wiederum Teil jeweils einer sich durchgehend von einer Keilfläche 6 zur anderen erstrecken linienförmigen Markierung 11. Allerdings sind hier die linienförmigen Markierungen 11 der einzelnen Pressbackenköpfe 2 nicht identisch, sondern vielmehr untereinander unterschiedlich ausgeführt. Nur in der in Fig. 4 gezeigten korrekten Anordnung der acht Pressbackenköpfe 2 bilden (bei vollständig geschlossenem Presswerkzeug) die linienförmigen Markierungen 11 der Pressbackenköpfe 2 zusammen eine sich über alle Pressbackenköpfe 2 erstreckende durchgehende Markierungslinie aus. Bei jeder von der vorgegebenen Anordnung abweichenden Montage der Pressbackenköpfe 2 ist demgegenüber die Markierungslinie ebenso unterbrochen wie im Falle einer Fehlbestückung.At the in Fig. 4 In the illustrated embodiment, the two markings 8 provided on the face of all press jaw heads 2 are in turn part of a line-shaped mark 11 extending continuously from one wedge surface 6 to the other Press jaw heads 2 are not identical, but rather different from one another. Only in the in Fig. 4 The correct arrangement of the eight pressing jaw heads 2 shown here form (with the pressing tool completely closed) the linear markings 11 of the pressing jaw heads 2 together form a continuous marking line extending over all pressing jaw heads 2. In the case of any assembly of the press jaw heads 2 that deviates from the predetermined arrangement, the marking line is interrupted, as is the case in the case of incorrect assembly.

Ersichtlich ist bei sämtlichen dargelegten und erläuterten Weiterbildungen möglich, jeweils durch verschiedene Farbgebung der Markierungslinien unterschiedlicher Pressbackenköpfe und/oder durch die Ausführung der Markierungslinien als vertiefte Rillen bzw. erhabene Stege eine zusätzliche auffällige Unterscheidbarkeit herbeizuführen.Obviously, in all of the developments presented and explained, it is possible to create an additional, conspicuous distinction through different coloring of the marking lines of different press jaw heads and / or through the execution of the marking lines as recessed grooves or raised webs.
