Abstract
Description
Die vorliegende Erfindung betrifft ein Biegewerkzeug zum Biegen von Hydraulik-Bogenarmaturen nach dem Oberbegriff des Anspruchs 1.The present invention relates to a bending tool for bending hydraulic bow fittings according to the preamble of claim 1.
Zur Verbindung von relativ zueinander beweglichen Druckaggregaten, beispielsweise bei Baumaschinen, wie Bagger-Armen, werden zur Versorgung von beweglichen Antriebszylindern mit Druckmittel flexible, druckfeste Hydraulikleitungen benötigt. Diese Leitungen sind mit zwei endseitigen Anschlussarmaturen konfektioniert. In vielen Fällen ist mindestens eine der Anschlussarmaturen als eine mit einem bestimmten Biegungswinkel gekrümmte Bogenarmatur ausgebildet, um im angeschlossenen Zustand einen möglichst knickfreien und allenfalls mit möglichst großem Radius gekrümmten Verlauf der Leitung zu erreichen. Jede Bogenarmatur besteht aus einem gebogenen rohrförmigen Schaft und zwei gegenüberliegenden Endbereichen mit flanschartigen Verbindungselementen.For connection of relatively movable printing units, for example in construction machines, such as excavator arms, flexible, pressure-resistant hydraulic lines are required to supply movable drive cylinders with pressure medium. These cables are assembled with two end connection fittings. In many cases, at least one of the connection fittings is designed as a curved with a certain bending angle bend fitting to achieve a possible kink-free and possibly curved with the largest possible radius course of the line in the connected state. Each curved fitting consists of a curved tubular shaft and two opposite end portions with flange-type connecting elements.
Solche Bogenarmaturen werden mit Biegewerkzeugen der genannten, gattungsgemäßen Art gebogen. Bisher war dies mit bekannten Biegewerkzeugen ohne eine Demontage des Werkzeuges (z. B. ohne Auseinanderschrauben) nur bis zu einem maximalen Biegungswinkel von bis zu 90° möglich.Such bow fittings are bent with bending tools of the aforementioned generic type. So far, this has been possible with known bending tools without disassembly of the tool (eg without unscrewing) only up to a maximum bending angle of up to 90 °.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Biegewerkzeug der genannten Art zu schaffen, welches mit konstruktiv einfachen Mitteln und ohne Demontage auch zum Biegen von Bogenarmaturen mit einem Biegungswinkel über 90° geeignet ist.The present invention has for its object to provide a bending tool of the type mentioned, which is also suitable for bending of curved fittings with a bending angle over 90 ° with structurally simple means and without disassembly.
Erfindungsgemäß wird dies durch die Merkmale des Anspruchs 1 erreicht. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen enthalten.This is achieved by the features of claim 1 according to the invention. Advantageous embodiments of the invention are contained in the dependent claims.
Demnach weist erfindungsgemäß der Biegekopf im Einspannbereich einen zur Schaffung eines Lösespiels relativ zu der gebogenen Bogenarmatur verschiebbaren Spannschlitten auf. Durch diese sehr einfache aber wirkungsvolle Maßnahme wird erreicht, dass die Bogenarmatur mit ihrem durch das flanschartige Anschlusselement verdickten Endbereich durch eine Lösebewegung des Spannschlittens so freigegeben wird, dass sie nachfolgend mit dem gebogenen Schaft aus der Rohr-Aufnahme entnommen werden kann.Accordingly, according to the invention, the bending head in the clamping area has a displaceable relative to the curved bow fitting to provide a clearance play Clamp on. By this very simple but effective measure is achieved that the curved armature is released with its thickened by the flange connection element end portion by a release movement of the clamping slide so that it can be subsequently removed with the bent shaft from the tube receptacle.

Ein erfindungsgemäßes Biegewerkzeug 1 ist zum Biegen von Hydraulik-Bogenarmaturen konzipiert. Eine solche Bogenarmatur 2 ist beispielhaft in Fig. 3 dargestellt. Sie besteht aus einem rohrförmigen Schaft 4 und zwei Endbereichen 6, 8. In den Endbereichen 6, 8 sind flanschartige Verdickungen als Verbindungs- bzw. Anschlusselemente vorhanden. Der Schaft 4 der Bogenarmatur 2 ist mit einem bestimmten Biegewinkel α gebogen bzw. zu biegen.An inventive bending tool 1 is designed for bending hydraulic bow fittings. Such a
Gemäß Fig. 1 bis 3 besteht das Biegewerkzeug 1 aus einem Biegekopf 10 mit einer nut- oder rinnenartigen, entsprechend einer gewünschten Biegekontur des Schaftes 4 verlaufenden Schaft-Aufnahme 12 und einem Einspannbereich 14 für den ersten Endbereich 6 der Bogenarmatur 2. Weiterhin besteht das Biegewerkzeug 1 aus einem im Einspannbereich 14 zum Einspannen des ersten Endbereichs 6 der Bogenarmatur 2 in Pfeilrichtung 15a gegen den Biegekopf 10 pressbaren Spannstück 16 sowie einem Anlegestück 18 zur abstützenden Anlage des zweiten Endbereichs 8 der Bogenarmatur 2 während des Biegevorgangs (siehe hierzu Fig. 3). Das Spannstück 16 ist nach dem Biegevorgang in Pfeilrichtung 15b vom Biegekopf 10 wegbewegbar.According to Fig. 1 to 3, the bending tool 1 consists of a
Zum Biegen des Schaftes 4 sind der Biegekopf 10 und das Anlagestück 18 relativ zueinander entsprechend der in Fig. 1 und 3 eingezeichneten Pfeile 20 verschwenkbar. Wie sich dabei aus Fig. 3 ergibt, war es bisher bei einem Biegewinkel α > 90° nicht ohne Weiteres möglich, die Armatur 2 aus dem Werkzeug 1 zu entnehmen, weil der erste Endbereich 6 aufgrund von radialen Kanten 22 nicht aus der Kontur im Einspannbereich 14 des Biegekopfes 10 gelöst werden konnte. Daher waren - ohne Demontage des Werkzeugs - nur Biegewinkel α ≤ 90° möglich.For bending the shaft 4, the
Erfindungsgemäß weist nun der Biegekopf 10 im Einspannbereich 14 einen zur Schaffung eines Lösespiels relativ zu der gebogenen Bogenarmatur 2 verschiebbaren Spannschlitten 24 auf. Dieser Spannschlitten 24 ist in Achsrichtung des ersten Endbereichs 6 der Bogenarmatur 2 und in Richtung des angrenzenden Schaftes 4 verschiebbar, und zwar bevorzugt gegen Federkraft aus einer Ausgangsstellung für den Biegevorgang in Pfeilrichtung 27 in eine Lösestellung zum Entnehmen der gebogenen Bogenarmatur 2. Zur Erzeugung der Rückstell-Federkraft ist zwischen dem Biegekopf 10 und dem Spannschlitten 24 mindestens eine Druckfeder 26, bevorzugt aber zwei Druckfedern 26, angeordnet (siehe hierzu Fig. 2 und 3).According to the invention, the
Durch Verschieben des Spannschlittens 24 in die Lösestellung entsteht zur Bogenarmatur 2 ein Lösespiel, so dass deren radialen Kanten 22 aus der inneren Kontur im Einspannbereich 14 freikommen und dann die Bogenarmatur 2 in Pfeilrichtung 29 aus der Schaft-Aufnahme 12 entnommen werden kann (Fig. 3). Dadurch sind maximale Biegewinkel α im Bereich von 150° bis 160° möglich.By moving the
In weiterer vorteilhafter Ausgestaltung der Erfindung ist eine Sperreinrichtung 28 derart vorgesehen, dass der Spannschlitten 24 im gespannten Zustand des Spannstückes 16 gegen Verschieben blockiert ist und erst nach Lösen des Spannstückes 16 zum Verschieben freigegeben wird. Wie sich aus Fig. 1 und 2 ergibt, weist die Sperreinrichtung 28 Formschlusselemente (30, 32) zwischen dem Spannstück 16 und dem Spannschlitten 24 derart auf, dass die Formschlusselemente im gespannten Zustand des Spannstückes 16 (Fig. 2) in Eingriff und im gelösten Zustand zumindest soweit außer Eingriff sind, dass der Spannschlitten 24 zur Schaffung des Lösespiels in Pfeilrichtung 27 verschiebbar ist. Die beschriebenen Formschlusselemente bestehen im dargestellten Ausführungsbeispiel aus mindestens einem Ansatz 30 und einer korrespondierenden, den Ansatz 30 aufnehmenden Ausnehmung 32. Dabei ist der Ansatz 30 entsprechend der Richtung einer Spannbewegungsachse 34 des Spannstückes 16 ausgerichtet (siehe Fig. 1). Bei der bevorzugten, dargestellten Ausführung weist der Spannschlitten 24 den mindestens einen Ansatz 30 und das Spannstück 16 die korrespondierende Ausnehmung 32 auf. Vorzugsweise greift dabei der im Querschnitt C-förmige, die Schaft-Aufnahme 12 im Einspannbereich 14 umschließende Spannschlitten 24 mit zwei Ansätzen 30 in korrespondierende Ausnehmungen 32 des Spannstückes 16 ein; siehe Fig. 2.In a further advantageous embodiment of the invention, a
Natürlich ist auch eine umgekehrte Ausführung möglich, wobei vorzugsweise das im Querschnitt etwa C-förmige, den Einspannbereich umschließende Spannstück 16 mit zwei Ansätzen in korrespondierende Ausnehmungen des Spannschlittens eingreift.Of course, a reverse embodiment is possible, wherein preferably in cross-section approximately C-shaped, the clamping area enclosing
In allen Fällen ist die Eingriff-Kontur der Formschlusselemente 30, 32 so ausgelegt, dass bei gelöstem Spannstück 16 ein ausreichendes Bewegungsspiel zum Verschieben des Spannschlittens 24 entsteht. Gemäß Fig. 1 kann dies durch schräge Kanten 36 zur Erweiterung der Ausnehmungen 32 realisiert werden. Im gespannten Zustand des Spannstückes 16 wird durch die Formschlusselemente 30, 32 eine formschlüssige Blockierung des Spannschlittens 24 gegen Verschiebung in Pfeilrichtung 27 gewährleistet.In all cases, the engagement contour of the
Wie sich schließlich noch aus Fig. 1 und 2 ergibt, ist der Spannschlitten 24 über eine Schiebeführung 38 mit dem Biegekopf 10 verbunden. Bei der dargestellten Ausführung ist die Schiebeführung 38 in Form einer T-Verbindung ausgeführt. Ebenfalls ist auch eine Schwalbenschwanzverbindung oder dergleichen geeignet.As finally results from FIGS. 1 and 2, the clamping
Die Erfindung ist nicht auf die dargestellten und beschriebenen Ausführungsbeispiele beschränkt, sondern umfasst auch alle im Sinne der Erfindung gleichwirkenden Ausführungen. Ferner ist die Erfindung bislang auch noch nicht auf die im Anspruch 1 definierte Merkmalskombination beschränkt, sondern kann auch durch jede beliebige andere Kombination von bestimmten Merkmalen aller insgesamt offenbarten Einzelmerkmalen definiert sein. Dies bedeutet, dass grundsätzlich praktisch jedes Einzelmerkmal des Anspruchs 1 weggelassen bzw. durch mindestens ein an anderer Stelle der Anmeldung offenbartes Einzelmerkmal ersetzt werden kann. Insofern ist der Anspruch 1 lediglich als ein erster Formulierungsversuch für eine Erfindung zu verstehen.The invention is not limited to the illustrated and described embodiments, but also includes all the same in the context of the invention embodiments. Furthermore, the invention has hitherto not been limited to the feature combination defined in claim 1, but may also be defined by any other combination of specific features of all individually disclosed individual features. This means that in principle virtually every individual feature of claim 1 can be omitted or replaced by at least one individual feature disclosed elsewhere in the application. In this respect, the claim 1 is to be understood only as a first formulation attempt for an invention.
