Description

Die Erfindung betrifft ein Presswerkzeug, mit mindestens zwei Pressbackenelementen, mit mindestens einem Gelenkelement, wobei mindestens ein Pressbackenelement aus mindestens zwei Schichten aufgebaut ist, wobei mindestens zwei Pressbackenelemente jeweils eine Presskontur aufweisen, wobei mindestens zwei Pressbackenelemente jeweils eine Betätigungsfläche aufweisen, wobei jeweils mindestens ein Gelenkelement jeweils mindestens zwei Pressbackenelemente gelenkig miteinander verbindet, wobei mindestens zwei Schichten stoffschlüssig miteinander verbunden sind und wobei mindestens zwei Schichten durch mindestens eine Schweißverbindung verbunden sind.The invention relates to a pressing tool having at least two pressing jaw elements, with at least one joint element, wherein at least one pressing jaw element is composed of at least two layers, wherein at least two pressing jaw elements each have a pressing contour, wherein at least two pressing jaw elements each have an actuating surface, wherein in each case at least one joint element each at least two pressing jaw elements hingedly interconnected, wherein at least two layers are materially interconnected and wherein at least two layers are connected by at least one welded joint.

Zum Herstellen von kaltverformten Verbindungen sind aus dem Stand der Technik verschiedenartige Presswerkzeuge bekannt. Beispielsweise werden Presswerkzeuge eingesetzt, um ein mit einem Fitting zusammengestecktes Rohr durch Kaltverformen der Steckverbindung mit dem Fitting kraft- sowie formschlüssig zu verbinden. Die Pressbackenelemente dieser Presswerkzeuge sind aus einem Stück, beispielsweise durch Verfahren des Gesenkschmiedens oder des Feingusses hergestellt, um die hohen erforderlichen Presskräfte ausüben zu können.For the production of cold-formed compounds, various types of pressing tools are known from the prior art. For example, pressing tools are used to positively and positively connect a mated with a pipe pipe by cold forming the connector with the fitting. The pressing jaw elements of these pressing tools are made in one piece, for example by drop forging or precision casting, in order to be able to exert the high pressing forces required.

Regelmäßig werden die Presswerkzeuge durch hydraulische Pressmaschinen angetrieben. So können Presskräfte von bis zu 100 kN und darüber hinaus erzeugt werden.Regularly, the pressing tools are driven by hydraulic pressing machines. Thus, pressing forces of up to 100 kN and beyond can be generated.

Es sind auch Presswerkzeuge mit schichtförmigen Pressbackenelementen bekannt, die mechanisch betätigt werden können, wobei diese nur geringere Presskräfte von bis zu 20 kN aufbringen können und deshalb für die oben genannte Anwendung nicht geeignet sind.There are also pressing tools with layered pressing jaw elements known that can be operated mechanically, these only lower pressing forces of up to 20 kN and are therefore not suitable for the above-mentioned application.

Zum Verpressen und Herstellen einer kaltverformten Verbindung zwischen einem Rohr und einem Fitting sind insbesondere die folgenden Presswerkzeuge bekannt.For pressing and producing a cold-formed connection between a pipe and a fitting, the following pressing tools are known in particular.

Für direktes Verpressen dienen Pressbacken, die über einen Bolzen mit einer Pressmaschine verbunden werden. Ist der Zugang zu dem zu verpressenden Bereich beengt, werden häufig Presswerkzeuge in Form von Pressringen oder Pressketten verwendet. Zum Verpressen wird in diesem Fall ein zweites Presswerkzeug, insbesondere eine Gelenkzugbacke verwendet, die an dem Pressring oder der Presskette angreift und so ein Verpressen ermöglicht.For pressing directly press jaws, which are connected via a bolt with a pressing machine. If access to the area to be compacted cramped, pressing tools in the form of pressing rings or compression chains are often used. For pressing in this case, a second pressing tool, in particular a Gelenkzugbacke is used, which engages the pressing ring or the pressing chain and thus enables compression.

Die zuvor genannten bekannten Presswerkzeuge weisen erhebliche Nachteile bei Ihrer Neuentwicklung auf, die im Folgenden erläutert werden sollen.The aforementioned known pressing tools have significant disadvantages in their new development, which will be explained below.

Bei der Neuentwicklung von Fittings müssen häufig auch neue Presswerkzeuge entwickelt werden. Dabei ist die Entwicklungszeit für ein neues Fitting, beispielsweise einige Wochen, erheblich kürzer als für ein neues Presswerkzeug, beispielsweise mehrere Monate, insbesondere ca. neun Monate, da ebenfalls neue Gesenke bzw. Gussformen zur Herstellung der Pressbackenelemente notwendig sind. Dies wirkt sich insbesondere negativ auf den wirtschaftlichen Faktor "time to market" aus, da das neue Fitting erst angeboten werden kann, wenn auch ein entsprechendes Presswerkzeug am Markt verfügbar ist.In the development of new fittings often new compression tools must be developed. The development time for a new fitting, for example a few weeks, is considerably shorter than for a new pressing tool, for example, several months, especially about nine months, as well as new dies or molds for the production of pressing jaw elements are necessary. This has a particularly negative effect on the economic factor "time to market" since the new fitting can only be offered if a corresponding pressing tool is available on the market.

Weiterhin ist die Entwicklung neuer Gesenke bzw. Gussformen für die Pressbackenelemente des neuen Presswerkzeugs sehr kostenintensiv. Dadurch bedingt sind die Herstellungsverfahren des Gesenkschmiedens bzw. Gießens für das Bereitstellen von neuen Presswerkzeugen in geringen Stückzahlen nur unzureichend geeignet. Gerade bei der Erschließung neuer Märkte sind aber erste Auflagen geringerer Stückzahlen ein begehrtes Mittel um schnell am Markt präsent zu sein und das Risiko eines nicht Durchgreifens des neuen Produktes - hier des Presswerkzeugs bzw. Fittings - zu begrenzen.Furthermore, the development of new dies or molds for the pressing jaw elements of the new pressing tool is very expensive. As a result, the production processes of drop forging or casting for the provision of new pressing tools in small numbers are only insufficiently suitable. Especially in the development of new markets, however, first editions of lesser quantities are a sought-after means to be present on the market quickly and to limit the risk of non-crackdown of the new product - here the pressing tool or fittings.

Aus dem Stand der Technik der US 2003/0230131 A1 ist ein Presswerkzeug bekannt, mit dem ein angemessener Schließgrad der Pressbacken gewährleistet bzw. bestimmt werden kann.From the prior art of US 2003/0230131 A1 a pressing tool is known with which an appropriate degree of closure of the pressing jaws can be ensured or determined.

Der Erfindung liegt das technische Problem zugrunde, ein Presswerkzeug und ein Verfahren zu seiner Herstellung anzugeben, das den durch die hohen Presskräfte bestehenden Anforderungen gerecht wird und schnell sowie kostengünstig bereit gestellt werden kann.The invention is based on the technical problem of specifying a pressing tool and a method for its production, which meets the requirements of the high pressing forces and can be provided quickly and inexpensively.

Erfindungsgemäß wird das technisch Problem mit einem Presswerkzeug gemäß Anspruch 1 gelöst.According to the technical problem is solved with a pressing tool according to claim 1.

Die Erfindung hat somit erkannt, dass eine mehrschichtige Ausgestaltung der Pressbackenelemente eine kostengünstige und schnelle Herstellung eines Presswerkzeugs ermöglicht und den erforderlichen hohen Presskräften durch stoffschlüssiges Verbinden von mindestens zwei Schichten standhalten kann. Die durch die hohen Presskräfte in den Schichten verursachten Spannungen können nicht zu einer Verformung der Schichten und damit des Pressbackenelements führen, da sich die Schichten gegenseitig gegen Verschieben und Verdrehen, bewirkt durch die stoffschlüssige Verbindung der Schichten, stützen.The invention has thus recognized that a multi-layered design of the pressing jaw elements enables a cost-effective and rapid production of a pressing tool and can withstand the required high pressing forces by materially joining at least two layers. The stresses caused by the high pressing forces in the layers can not lead to a deformation of the layers and thus of the pressing jaw element, since the layers mutually against displacement and twisting, effected by the cohesive connection of the layers, supporting.

Diese Sandwichbauweise der Pressbackenelemente hat besondere Vorteile. Zunächst ist das Bereitstellen der Schichten, beispielsweise durch Laserschneiden der Konturen aus Blechen, sehr kostengünstig und schnell zu bewerkstelligen.This sandwich construction of the pressing jaw elements has particular advantages. First, the deployment of the Layers, for example, by laser cutting the contours of sheets, very cost effective and fast to accomplish.

Weiterhin können konstruktive Änderungen des Beschnitts des Pressbackenelements durch einfaches Ändern des Schnittprogramms direkt umgesetzt werden. Es müssen also keine teuren und langwierigen Formänderungen, beispielsweise des Gesenks beim Gesenkschmieden oder der Gussform beim Feinguss vorgenommen werden.Furthermore, structural changes of the cut of the pressing jaw element can be implemented directly by simply changing the cutting program. It must therefore be made no costly and lengthy changes in shape, for example, the die in drop forging or the casting mold during precision casting.

Zudem wird die Flexibilität während der Produktentwicklung durch Bereitstellen eines frühen jedoch repräsentativen Prototyps erheblich erhöht. Die sich im Entwicklungsprozess ergebenen notwendigen Änderungen können jederzeit im Schnittprogramm aufgenommen werden.In addition, flexibility is significantly increased during product development by providing an early but representative prototype. The necessary changes in the development process can be included in the editing program at any time.

Ein erfindungsgemäßes Presswerkzeug kann dadurch gekennzeichnet sein, dass mindestens ein Verbindungselement vorgesehen ist, wobei das Verbindungselement mit mindestens einem Gelenkelement gelenkig verbunden ist und mindestens zwei Pressbackenelemente gelenkig miteinander verbindet.An inventive pressing tool may be characterized in that at least one connecting element is provided, wherein the connecting element is hingedly connected to at least one joint element and at least two pressing jaw elements hingedly interconnected.

Hierdurch können Presswerkzeuge mit komplizierten Schließkinematiken, wie beispielsweise Pressbacken oder Gelenkzugbacken konstruiert werden. Solche Presswerkzeuge können direkt an Pressmaschinen angeschlossen werden. Dafür wird an dem Verbindungselement ein Halteelement vorgesehen. Das Presswerkzeug kann dann über einen Bolzen mit der Pressmaschine verbunden werden und zur direkten Pressung einer Fitting/Rohr Verbindung genutzt werden oder ein weiteres Presswerkzeug betätigen.As a result, pressing tools can be constructed with complicated closing kinematics, such as press jaws or joint jaws. Such pressing tools can be connected directly to press machines. For this purpose, a holding element is provided on the connecting element. The pressing tool can then be connected via a bolt with the pressing machine and used for direct pressing of a fitting / pipe connection or actuate another pressing tool.

Auch können mehrgliedrigere Pressketten durch Vorsehen eines Verbindungselements ausgestaltet werden.Also, multi-link press chains can be configured by providing a connector.

Das erfindungsgemäße Presswerkzeug ist dadurch gekennzeichnet, dass mindestens zwei Schichten durch eine Schweißverbindung stoffschlüssig verbunden sind. Die Schichten können auf diese Art effizient nur an den notwendigen Stellen durch Schweißnähte verschweißt werden. Die Schweißnähte sind so an dem Pressbackenelement angeordnet, dass sie sich nicht im Bereich der Presskontur bzw. der Betätigungsflächen befinden. Dann kann eine aufwändige Nachbearbeitung der Schweißnähte unnötig sein, wodurch weiterhin Kosten und Zeit eingespart werden können.The pressing tool according to the invention is characterized in that at least two layers are materially connected by a welded connection. The layers can be welded in this way efficiently only in the necessary places by welds. The weld seams are arranged on the pressing jaw element such that they are not located in the area of the pressing contour or the actuating surfaces. In this case, time-consuming reworking of the weld seams can be unnecessary, as a result of which further costs and time can be saved.

Alternativ können mindestens zwei Schichten durch eine Klebeverbindung stoffschlüssig verbunden sein. Insbesondere kann die Klebeverbindung zwischen zwei Schichten angeordnet sein, so dass die Klebeverbindung schnell aufgetragen werden kann. So kann, bei Verwendung eines schnell härtenden Klebers, das Presswerkzeug direkt weiter montiert werden, wodurch eine weitere Zeitersparnis erreicht werden kann.Alternatively, at least two layers can be adhesively bonded by an adhesive bond. In particular, the adhesive bond can be arranged between two layers, so that the adhesive bond can be applied quickly. Thus, when using a fast-curing adhesive, the pressing tool can be directly mounted further, whereby a further time savings can be achieved.

Zudem können mindestens zwei Schichten durch mindestens eine Nietverbindung formschlüssig verbunden sein. Beispielsweise können Nieten vorgesehen werden, die die Schichten gegeneinander vorfixieren. Die stoffschlüssige Verbindung kann dann ohne die Gefahr der Verschiebung der Schichten hergestellt werden.In addition, at least two layers can be positively connected by at least one rivet connection. For example, rivets can be provided which pre-fix the layers against each other. The cohesive connection can then be made without the risk of shifting the layers.

In einer alternativen Ausführungsform können mindestens zwei Schichten durch mindestens eine Schraubverbindung kraftschlüssig verbunden sein. Dadurch kann die Vorfixierung der Schichten stabiler gestaltet werden und zudem durch Lösen der Schrauben auf einfache Weise wieder getrennt werden, bevor eine stoffschlüssige Verbindung einzelner Schichten vorgenommen wird.In an alternative embodiment, at least two layers can be non-positively connected by at least one screw connection. This allows the Prefixation of the layers are made more stable and also be easily separated again by loosening the screws before a cohesive connection of individual layers is made.

Eine besonders bevorzugte Ausführungsform ist dadurch gekennzeichnet, dass die Schichten aus Blechen hergestellt sind. Bleche sind vorgefertigt in reichhaltiger Auswahl und Güte verfügbar und eignen sich in besonderem Maße zur Verwendung für das zuvor genannte erfindungsgemäße Presswerkzeug.A particularly preferred embodiment is characterized in that the layers are made of sheets. Sheets are prefabricated in abundant selection and quality available and are particularly suitable for use for the aforementioned pressing tool according to the invention.

Erfindungsgemäß wird das technische Problem auch durch ein Verfahren zur Herstellung eines Pressbackenelements für ein Presswerkzeug gelöst, wobei in einem ersten Schritt die Schichten hergestellt werden, wobei in einem zweiten Schritt die Schichten übereinander angeordnet werden und wobei in einem letzten Schritt die Schichten stoffschlüssig miteinander verbunden werden.According to the invention, the technical problem is also solved by a method for producing a pressing jaw element for a pressing tool, wherein the layers are produced in a first step, wherein in a second step, the layers are arranged one above the other and wherein in a final step, the layers are materially interconnected ,

Dabei können die Schichten aus Blechen hergestellt werden. Beispielsweise können die Schichten durch Laserschneiden hergestellt werden, insbesondere aus Blechen geschnitten werden.The layers can be made from sheet metal. For example, the layers can be produced by laser cutting, in particular be cut from sheets.

In einem letzten Schritt können die Schichten durch Verschweißen und/oder Verkleben miteinander stoffschlüssig verbunden werden.In a last step, the layers can be bonded together by welding and / or gluing together.

Zum Vereinfachen der Verarbeitung können in einem Schritt vor dem stoffschlüssigen Verbinden die Schichten durch Vernieten und/oder Verschrauben form- bzw. kraftschlüssig miteinander verbunden werden.To simplify the processing, the layers can be connected to one another by riveting and / or screwing in a single step before the integral connection.

Im Folgenden wird die Erfindung anhand spezieller Ausführungsbeispiele und der beigefügten Zeichnung näher erläutert. Die Zeichnung zeigt in

In the following the invention will be explained in more detail with reference to specific embodiments and the attached drawing. The drawing shows in

Fig. 2a, b

Fig. 1a und deren Ansicht Z in Fig. 1b zeigen ein Presswerkzeug, ausgeführt als Pressring 1, mit zwei Pressbackenelementen 3, mit einem Gelenkelement 5, wobei beide Pressbackenelemente 3 aus zwei Schichten 7 aufgebaut sind, wobei beide Pressbackenelemente 3 jeweils eine Presskontur 9 aufweisen, wobei beide Pressbackenelemente 3 jeweils eine Betätigungsfläche 11 aufweisen und wobei das eine Gelenkelement 5 beide Pressbackenelemente 3 gelenkig miteinander verbindet. Fig. 1a and their view Z in Fig. 1b show a pressing tool, designed as a press ring 1, with two pressing jaw elements 3, with a joint element 5, wherein both pressing jaw elements 3 are constructed of two layers 7, wherein both pressing jaw elements 3 each have a pressing contour 9, wherein both pressing jaw elements 3 each have an actuating surface 11 and wherein the one hinge element 5 connects both pressing jaw elements 3 hinged together.

Für gleichartige Elemente wurden wegen der Übersichtlichkeit gleiche Bezugszeichen verwendet, obwohl selbstverständlich jedes Element für sich eine eigenständige Form aufweisen kann. Sind beispielsweise mehr als zwei Pressbackenelemente 3 vorhanden, kann eine Betätigungsfläche 11 auch nur an zwei Pressbackenelemente ausgeführt sein, wie der Erläuterung zu Fig. 3a und 3b weiter unten zu entnehmen ist. Natürlich können auch die Schichten 7 jeweils unterschiedliche Dicken und Formen aufweisen.For similar elements, the same reference numerals have been used for the sake of clarity, although of course each element can have an independent form of its own. If, for example, more than two pressing jaw elements 3 are present, an actuating surface 11 can only be attached to two pressing jaw elements be executed as the explanation to Fig. 3a and 3b can be seen below. Of course, too Layers 7 each have different thicknesses and shapes.

Bei der in Fig. 1a und 1b gezeigten Ausführungsform sind die zwei Schichten 7 jeweils stoffschlüssig durch Schweißnähte 13 miteinander verbunden.At the in Fig. 1a and 1b In the embodiment shown, the two layers 7 are in each case materially connected to one another by welding seams 13.

Wird das Presswerkzeug 1 mit seinen Presskonturen 9 um den zu verpressenden Umfang eines Fittings (nicht gezeigt) gelegt, kann durch Ausüben einer Klemmkraft in Richtung der Pfeile A auf die Betätigungsflächen 11 das Fitting mit einem in das Fitting gesteckten Rohr (nicht gezeigt) verpresst werden. Dabei wirken die Schweißnähte 13 den Spannungen innerhalb der einzelnen Schichten 7 entgegen, die durch die hohen Presskräfte verursacht werden, so dass sich die Schichten 7 nicht gegeneinander verformen und die Pressbackenelemente 3 ihre Form beibehalten sowie eine exakte Verpressung des Fittings über die Presskonturen 9 bewirken können.If the pressing tool 1 with its pressing contours 9 is placed around the circumference of a fitting (not shown), by applying a clamping force in the direction of the arrows A to the actuating surfaces 11, the fitting can be crimped with a tube (not shown) inserted into the fitting , In this case, the welds 13 counteract the stresses within the individual layers 7, which are caused by the high pressing forces, so that the layers 7 do not deform against each other and the pressing jaw elements 3 retain their shape and can cause an exact compression of the fitting on the pressing contours 9 ,

In Fig. 2a und in deren Ansicht Y in Fig. 2b ist eine Ausführungsform des Presswerkzeugs als Pressbacke 15 gezeigt, mit zwei Pressbackenelementen 3, mit zwei Gelenkelementen 5, wobei beide Pressbackenelemente 3 aus drei Schichten 7, welche aus Blechen gefertigt sein können, aufgebaut ist, wobei beide Pressbackenelemente 3 jeweils eine Presskontur 9 aufweisen, wobei beide Pressbackenelemente 3 jeweils eine Betätigungsfläche 11 aufweisen und wobei beide Gelenkelemente 5 beide Pressbackenelemente 3 gelenkig miteinander verbinden.In Fig. 2a and in whose view Y in Fig. 2b an embodiment of the pressing tool is shown as pressing jaw 15, with two pressing jaw members 3, with two hinge elements 5, wherein both pressing jaw members 3 of three layers 7, which may be made of sheets, is constructed, wherein both pressing jaw elements 3 each have a pressing contour 9, wherein both pressing jaw elements 3 each have an actuating surface 11 and wherein both joint elements 5 connect both pressing jaw elements 3 hinged together.

Wie deutlich in Fig. 2a und 2b gezeigt, sind die Formen der Elemente des Presswerkzeugs 15, beispielsweise die beiden Presskonturen 9 verschieden von dem.vorherigen Ausführungsbeispiel ausgestaltet.How clearly in Fig. 2a and 2b are shown, the shapes of the elements of the pressing tool 15, for example, the two Press contours 9 differently designed from the.vorherigen embodiment.

Wiederum sind Schweißnähte 13 zur stoffschlüssigen Verbindung aller drei Schichten 7 vorgesehen, wobei die Schweißnähte 13 so angeordnet sind, dass sie nicht im Bereich der Betätigungsflächen 11 oder der Presskontur 9 liegen und eine aufwändige Nachbearbeitung der Schweißnähte 13 unterbleiben kann.Again, welds 13 are provided for material connection of all three layers 7, wherein the welds 13 are arranged so that they do not lie in the region of the actuating surfaces 11 or the pressing contour 9 and a costly reworking of the welds 13 can be omitted.

Weiterhin sind in Fig. 2a und 2b zwei Verbindungselemente 17 gezeigt, wobei beide Verbindungselemente 17 mit beiden Gelenkelementen 5 gelenkig verbunden sind und die beiden Pressbackenelemente 3 gelenkig miteinander verbinden. Des weiteren sind die Schichten 7 durch Nietverbindungen 19 formschlüssig verbunden.Furthermore, in Fig. 2a and 2b two connecting elements 17 are shown, wherein both connecting elements 17 are pivotally connected to two joint elements 5 and connect the two pressing jaw elements 3 hinged together. Furthermore, the layers 7 are connected in a form-fitting manner by rivet connections 19.

Ein weiteres Halteelement 21, das an jeweils einem Verbindungselement 17 angeordnet ist, dient zur Verbindung des Presswerkzeugs 15 mit einer Pressmaschine (nicht gezeigt).A further holding element 21, which is arranged on a respective connecting element 17, serves to connect the pressing tool 15 to a pressing machine (not shown).

Ein solches Presswerkzeug 15 kann direkt an ein Fitting (nicht gezeigt) mit seinen Presskonturen 9 angesetzt werden und für ein Verpressen mit einem Rohr (nicht gezeigt) verwendet werden. Dafür übt die Pressmaschine eine Kraft in Richtung der Pfeile B auf die Betätigungsflächen 11 der Pressbackenelemente 3 aus.Such a pressing tool 15 can be applied directly to a fitting (not shown) with its pressing contours 9 and used for pressing with a tube (not shown). For this purpose, the pressing machine exerts a force in the direction of the arrows B on the actuating surfaces 11 of the pressing jaw elements 3.
