Description

VORRICHTUNG UND VERFAHREN ZUM SCHALEN UND TRENNEN VON MEHREREN SCHLAUCHLAGEN AUFWEISENDEN HYDRAULIKSCHLÄUCHEN DEVICE AND METHOD FOR SHELLING AND SEPARATING HYDRAULIC HOSES HAVING SEVERAL HOSES
Technisches Gebiet Technical field
Die Erfindung bezieht sich auf eine Vorrichtung zum Schälen und Trennen von mehreren Schlauchlagen aufweisenden Hydraulikschläuchen, mit einer um eine Drehachse rotierbar gelagerten Bearbeitungseinheit, die ein radial zur Drehachse anstellbares Trennwerkzeug umfasst. The invention relates to a device for peeling and separating hydraulic hoses having a plurality of hose layers, having a processing unit which is rotatably mounted about an axis of rotation and which comprises a separating tool which can be set radially to the axis of rotation.
Stand der Technik State of the art
Aus dem Stand der Technik sind Vorrichtungen zum Trennen von eine Decklage, eine metallische Druckträgerlage sowie eine Schlauchseele aufweisenden Hyd raulikschläuchen bekannt (EP 0085284 A1 ). Beim Bearbeitungsvorgang werden zunächst die Deck- und die metallische Druckträgerlage eines zu bearbeitenden Schlauchabschnittes mittels einer um den Schlauchabschnitt rotierbaren Kreissä ge als Trennwerkzeug durchtrennt, wonach die übrigbleibende, gummierte Schlauchseele mit einem Abstichmesser durchschnitten wird. Devices for separating a cover layer, a metallic pressure carrier layer and a hose core having hydraulic raulikschläuche are known from the prior art (EP 0085284 A1). In the machining process, the cover and the metallic pressure carrier layer of a hose section to be machined are first cut by means of a circular saw that can be rotated around the hose section as a separating tool, after which the remaining, rubberized hose core is cut with a scraper.
Um überdies Hydraulikschlauchenden für eine Konfektionierung vorzupräparieren sind Schälvorrichtungen bekannt, die einen Haltedorn zum Aufstecken des zu be arbeitenden Schlauchendes, sowie ein um den Haltedorn rotierbares und radial gegenüber diesem anstellbares Schälwerkzeug aufweisen. Nachteilig ist daran al lerdings, dass ein zusätzliches Durchtrennen der Schlauchlagen aufgrund des Haltedorns nicht möglich ist, sodass pro Schälvorgang lediglich ein, mittels einer Trennvorrichtung bereits abgelängtes bzw. im Anschluss an den Schälvorgang abzulängendes Schlauchende bearbeitet werden kann. Infolgedessen erweist sich die Herstellung konfektionierbarer Schlauchenden grundsätzlich als sehr zeitauf wändig und ineffizient, weil für die Präparierung jeweils eines konfektionierbaren Schlauchendes immer gesonderte Schäl- und Trennvorgänge nötig sind. Darüber hinaus kommt es bei derartigen Schälvorgängen regelmäßig zu einer Schädigung des Schlauchseelenmaterials aufgrund der zwischen Haltedorn und Schlauchsee le entstehenden Reibungswärme. In addition, to prepare hydraulic hose ends for confectioning, peeling devices are known which have a holding mandrel for plugging on the hose end to be worked, as well as a rotating and radially adjustable peeling tool about the holding mandrel. The disadvantage of this, however, is that an additional severing of the hose layers is not possible due to the holding mandrel, so that only one hose end that has already been cut to length or can be cut to length after the peeling process can be processed per peeling process. As a result, the manufacture of ready-to-use hose ends generally proves to be very time-consuming and inefficient, because one ready-to-use one is required for the preparation Separate peeling and separating processes are always necessary. In addition, such peeling processes regularly damage the tube core material due to the frictional heat generated between the holding mandrel and the tube core le.
Darstellung der Erfindung Presentation of the invention
Der Erfindung liegt somit die Aufgabe zugrunde, eine Vorrichtung der eingangs geschilderten Art zu schaffen, die bei kompakter Bauweise eine zeiteffiziente Her stellung zweier konfektionierbarer Schlauchenden in einem Bearbeitungsvorgang ermöglicht, wobei die Gefahr einer Schädigung der Schlauchseele vermieden wird. The invention is therefore an object of the invention to provide a device of the type described which, with a compact design, enables time-efficient manufacture of two hose ends that can be assembled in one machining process, the risk of damage to the hose core being avoided.
Die Erfindung löst die gestellte Aufgabe dadurch, dass zwei in Richtung der Dreh achse voneinander beabstandete Klemmvorrichtungen zum lösbaren Festlegen eines Hydraulikschlauches vorgesehen sind, zwischen denen in einer Bearbei tungslage ein in Richtung der Drehachse verlagerbares und unabhängig vom Trennwerkzeug radial zur Drehachse anstellbares Schälwerkzeug angeordnet ist. The invention solves this problem in that two clamping devices spaced apart in the direction of the axis of rotation are provided for releasably fixing a hydraulic hose, between which, in a processing position, a displaceable in the direction of the axis of rotation and independently of the cutting tool radially adjustable to the axis of rotation peeling tool is arranged.
Zufolge dieser Merkmale können in einem Bearbeitungsvorgang, also ohne dass der zu bearbeitende Hydraulikschlauch für den Schäl- bzw. Trennvorgang jeweils neu justiert und festgelegt werden müsste, zwei konfektionierbare Schlauchenden geschaffen werden, weil die gemeinsame Gesamtkonfektionslänge beider Schlau chenden zunächst durch das Schälwerkzeug abgeschält und der Schlauch an schließend im abgeschälten Abschnitt vom Trennwerkzeug durchtrennt wird. Unter dem Begriff Hydraulikschlauch kann dabei jeder Industrieschlauch unabhängig seines Durchmessers verstanden werden, der zur Leitung von unter Druck ste henden Medien geeignet ist. Unter einer Festlegung des Hydraulikschlauches wird in diesem Zusammenhang verstanden, dass der Hydraulikschlauch im festgeleg ten Zustand weder um seine Längsachse verdreht noch entlang seiner Längsrich tung verschoben werden kann. Da der Hydraulikschlauch demnach beim Bearbei tungsvorgang über zwei in Richtung der Drehachse voneinander beabstandete, außen an der Decklage des Schlauches angreifende Klemmvorrichtungen festge- legt wird, können die beim Schälvorgang auftretenden, auf den Hydraulikschlauch wirkenden Schubkräfte über den sich dabei bildenden Kraftschluss zwischen den Klemmvorrichtungen und dem Hydraulikschlauch abgetragen und somit eine Ver drehung des Schlauches um bzw. eine Verschiebung in dessen Längsachse wirk sam vermieden werden, während die Schlauchseele keinen schädlichen Reibkräf ten ausgesetzt wird. Um zuverlässige Bearbeitungsbedingungen zu ermöglichen, können die Klemmvorrichtungen so angeordnet sein, dass die Längsachse des durch die Klemmvorrichtungen festgelegten Hydraulikschlauches mit der Dreh achse zusammenfällt, weil dadurch eine gemeinsame zentrierte Bezugsachse zwischen Bearbeitungseinheit und Hydraulikschlauch für die Zustellbewegungen der Werkzeuge definiert wird. Die Klemmvorrichtungen können beispielsweise als die jeweiligen Schlauchabschnitte umfangsseitig umschließende Schneckenräder ausgebildet sein, die mehrere innenumfangsseitig angeordnete, sowie zum Schneckenradmittelpunkt bzw. zur Drehachse in Abhängigkeit der Schnecken radstellung radial verlagerbare Klemmelemente zum Festklemmen des Hydraulik schlauches umfassen. Um überdies einen Schmutzeintrag in den Schlauch beim Bearbeitungsvorgang aufgrund von Schneidspänen zu vermeiden, empfiehlt es sich, die Schlauchseele mittels eines radial zur Drehachse anstellbaren Abstich werkzeuges zu durchtrennen, wobei der Abstichvorgang bei rotierender Bearbei tungseinheit als umlaufender Schnitt geführt werden kann. Besonders günstige Abtrennbedingungen ergeben sich allerdings, wenn im stationären Zustand der Bearbeitungseinheit gegenüber der Schlauchseele ein gerader, also in einer Nor malebene zur Schlauchlängsachse verlaufender Schnitt durch die Schlauchseele erfolgt, weil dadurch die Bildung von in den Schlauch gelangenden Schneidspä nen vermieden werden kann. Die erfindungsgemäße Vorrichtung ist grundsätzlich zum Schälen und Trennen von druckfesten technischen Schläuchen unterschied lichster Größenabmessungen, beispielsweise auch für Industrieschläuche mit ei nem Innendurchmesser über 50 mm, geeignet. As a result of these features, two attachable hose ends can be created in one machining process, i.e. without the hydraulic hose to be machined for the peeling or separating process having to be readjusted and fixed, because the overall overall length of the two hose ends is first peeled off by the peeling tool and the Hose is then cut in the peeled section by the cutting tool. The term hydraulic hose can be understood to mean any industrial hose, regardless of its diameter, which is suitable for conveying media under pressure. In this context, a definition of the hydraulic hose is understood to mean that the hydraulic hose in the defined state can neither be rotated about its longitudinal axis nor displaced along its longitudinal direction. Since the hydraulic hose is accordingly fixed during the machining process via two clamping devices spaced apart in the direction of the axis of rotation and acting externally on the cover layer of the hose. sets, the shear forces occurring during the peeling process, acting on the hydraulic hose, can be removed via the resulting frictional connection between the clamping devices and the hydraulic hose and thus a rotation of the hose or a shift in its longitudinal axis can be effectively avoided while the hose core is not exposed to harmful friction forces. In order to enable reliable machining conditions, the clamping devices can be arranged in such a way that the longitudinal axis of the hydraulic hose defined by the clamping devices coincides with the axis of rotation, because this defines a common centered reference axis between the processing unit and the hydraulic hose for the infeed movements of the tools. The clamping devices can, for example, be designed as worm wheels enclosing the respective hose sections on the circumferential side, which comprise a plurality of clamping elements arranged on the inner circumferential side and wheel position radially displaceable to the worm wheel center or to the axis of rotation depending on the worm wheel position, for clamping the hydraulic hose. In order to prevent dirt from entering the hose during the machining process due to cutting chips, it is advisable to cut the hose core using a tapping tool that can be adjusted radially to the axis of rotation, whereby the tapping process can be carried out as a circumferential cut while the machining unit is rotating. Particularly favorable separation conditions result, however, when in the stationary state of the processing unit with respect to the hose core, a straight cut, that is to say in a normal plane to the longitudinal axis of the hose, is made through the hose core because this prevents the formation of cutting chips entering the hose. The device according to the invention is basically suitable for peeling and separating pressure-resistant technical hoses of various sizes, for example also for industrial hoses with an inside diameter of over 50 mm.
Um beim Trennvorgang der Decklage eine Wulstbildung bzw. ein Auftulpen sowie beim Trennvorgang der metallischen Druckträgerlage eine Funkenbildung zu ver meiden, wird vorgeschlagen, dass die Bearbeitungseinheit eine Bandsäge als Trennwerkzeug aufweist. Es hat sich dabei überraschenderweise gezeigt, dass durch das eingesetzte Sägeband einerseits beim Trennvorgang eine vernachläs sigbare Schnittwärme erzeugt wird und dass das Sägeband andererseits zu einer geringeren Funkenbildung beim Durchtrennen der metallischen Druckträgerlage neigt. Aufgrund der deutlich geringeren Schnittwärme beim Trennvorgang können thermisch bedingte Schädigungen bzw. Verformungen der Decklage sowie eine Schädigung der Druckträgerlage vermieden werden. Besonders günstige Schnitt bedingungen ergeben sich in diesem Zusammenhang beim Einsatz diamantbe schichteter Sägebänder. Um zudem die thermische Belastung für die zu trennen den Schlauchlagen sowie die Funkenbildung weiter zu verringern, empfiehlt es sich, kurze, aufeinanderfolgende Trennintervalle vorzusehen, sodass das während eines Trennvorganges um den Schlauch rotierende Trennwerkzeug mehrfach ge genüber dem Schlauch zugestellt bzw. zurückgezogen wird. Es hat sich außerdem gezeigt, dass beim Einsatz von aus dem Stand der Technik bekannten, in unmit telbarer Nähe des Schneidspalts angeordneten Absaugvorrichtungen die Wärme abfuhr des Sägebandes durch den Saugluftstrom zusätzlich verbessert werden kann. In order to avoid the formation of bulges or tulping during the separation process of the cover layer and to avoid spark formation during the separation process of the metallic pressure carrier layer, it is proposed that the processing unit have a band saw as a separation tool. Surprisingly, it has been shown that a negligible cutting heat is generated on the one hand by the saw band used during the cutting process and on the other hand the saw band tends to produce less sparks when cutting through the metallic print carrier layer. Due to the significantly lower cutting heat during the separation process, thermally induced damage or deformation of the top layer and damage to the print carrier layer can be avoided. In this context, particularly favorable cutting conditions result when using diamond-coated saw bands. In order to further reduce the thermal load on the hose layers to be separated and the sparking, it is advisable to provide short, successive separation intervals so that the separation tool rotating around the hose during a separation process is fed or withdrawn several times relative to the hose. It has also been shown that when using suction devices known from the prior art and arranged in the immediate vicinity of the cutting gap, the heat dissipation of the saw band can be additionally improved by the suction air flow.
Der Einsatz einer Bandsäge im Zusammenhang mit Trennvorrichtungen für Hyd- raulikschläuche stellt den Fachmann aufgrund der dabei konstruktionsbedingt pa rallel nebeneinander verlaufenden Bandsägewirkabschnitte vor die Problemstel lung, dass Zusatzmaßnahmen getroffen werden müssen, die sicherstellen, dass sich beim Trennvorgang lediglich einer der beiden Bandsägewirkabschnitte im Eingriff mit den abzutrennenden Schlauchlagen befindet, ohne dass dadurch das Schnittbild negativ beeinträchtigt wird. The use of a band saw in connection with separating devices for hydraulic hoses presents the specialist with the problem due to the construction-related parallel band saw sections that additional measures have to be taken to ensure that only one of the two band saw sections engages during the cutting process the hose layers to be separated, without adversely affecting the sectional view.
Um vor diesem Flintergrund ein gerades, nämlich parallel zur Normalebene der Schlauchlängsachse verlaufendes Schnittbild bei dennoch kompakter Bauweise der Vorrichtung zu ermöglichen, wird vorgeschlagen, dass das Sägeband über zwei im Wesentlichen parallel zur Drehachse drehbar gelagerte Umlenkrollen um laufend geführt ist und im Wirkabschnitt der Bandsäge aus seiner Umlauflage so ausgelenkt ist, dass die Sägeblattflächennormale parallel zur Drehachse verläuft. Dies bedeutet, dass die an die Schneidkante bzw. den der Schneidkante gegen überliegenden Bandrücken anschließenden Bandflächen in der Umlauflage des Sägebandes eine im Wesentlichen radial zur Drehachse verlaufende Flächennor male aufweisen und nur im Wirkabschnitt der Bandsäge das Sägeband beispiels weise über Führungsrollen um etwa 90° so umgelenkt wird, dass die Bandflächen in einer Normalebene der Drehachse verlaufen, sodass die Schneidkante radial in Richtung der Drehachse an einen Flydraulikschlauch angestellt werden kann. Zu folge dieser Maßnahmen kann die Bandsäge überdies so an der Bearbeitungsein heit angeordnet sein, dass die Antriebsrollenachse der Bandsäge parallel zur Drehachse ausgerichtet ist, wodurch sich in weiterer Folge der Schwerpunkt des Bandsägeantriebes in relativ geringem radialen Abstand zur Drehachse befinden kann und die Vorrichtung somit nicht nur eine kompakte Bauweise aufweisen kann, sondern auch eine geringere Unwucht bei der Rotationsbewegung des Be arbeitungsvorganges besitzt. In order to enable a straight sectional view, namely parallel to the normal plane of the longitudinal axis of the hose, with a nevertheless compact construction of the device against this background, it is proposed that the saw band be guided continuously over two deflection rollers which are rotatably mounted parallel to the axis of rotation and in the effective section of the band saw its circumferential position is deflected so that the saw blade surface normal runs parallel to the axis of rotation. This means that the band surfaces adjoining the cutting edge or the band back opposite the cutting edge in the circulating position of the Saw band have a surface that is essentially radial to the axis of rotation and only in the effective section of the band saw the saw band is deflected, for example via guide rollers, by approximately 90 ° in such a way that the band surfaces run in a normal plane of the axis of rotation so that the cutting edge radially in the direction of the axis of rotation a fly hydraulic hose can be used. To follow these measures, the band saw can also be arranged on the processing unit so that the drive roller axis of the band saw is aligned parallel to the axis of rotation, as a result of which the center of gravity of the band saw drive can be located at a relatively small radial distance from the axis of rotation and therefore the device cannot can only have a compact design, but also has a lower imbalance in the rotational movement of the machining operation.
Um die Zugänglichkeit des Schneidspalts, beispielsweise zu Revisionszwecken durch einen Maschinenführer, zu verbessern, kann zwischen den Klemmvorrich tungen in einer Bearbeitungslage ein in Richtung der Drehachse verlagerbares und unabhängig vom Trennwerkzeug radial zur Drehachse anstellbares Abstich werkzeug angeordnet sein. Dadurch muss das Abstichwerkzeug nicht von vornhe rein exakt über dem Schneidspalt und in der durch die Schnittrichtung definierte Wirkebene des Trennwerkzeugs ausgerichtet sein bzw. muss sich das Abstich werkzeug samt Zustelltrieb nicht in unmittelbarer Nähe zum Trennwerkzeug befin den, sondern das Abstichwerkzeug muss erst, nachdem die Decklage und Druck trägerlage des Schlauches vom Trennwerkzeug durchtrennt worden sind, in Rich tung der Drehachse verlagert und für den Abstichvorgang gesondert in Position gebracht werden. Zufolge dieser Maßnahme ist der Schneidspalt nicht durch zu viele bauliche Einrichtung verdeckt und somit zu jeder Zeit gut sichtbar und zu gänglich. In order to improve the accessibility of the cutting gap, for example for revision purposes by a machine operator, a tapping tool that can be displaced in the direction of the axis of rotation and can be adjusted radially to the axis of rotation independently of the cutting tool can be arranged between the clamping devices in a processing position. As a result, the tapping tool does not have to be aligned exactly above the cutting gap and in the effective plane of the cutting tool defined by the cutting direction, or the tapping tool and feed drive need not be in the immediate vicinity of the cutting tool, but the tapping tool only has to be after the Cover layer and pressure carrier layer of the hose have been severed by the cutting tool, shifted in the direction of the axis of rotation and brought into position separately for the tapping process. As a result of this measure, the cutting gap is not covered by too many structural devices and is therefore clearly visible and accessible at all times.
Damit sowohl die Markierung des abzuschälenden Schlauchabschnittes als auch die Markierung der jeweiligen Einstecktiefen für an die konfektionierbaren Schlau chenden aufgesteckte Armaturen nicht in einem gesonderten manuellen Arbeits schritt vor dem eigentlichen Bearbeitungsvorgang erfolgen muss und dennoch ei ne kompakte Bauweise der Maschine erreicht wird, empfiehlt es sich, dass zwi- sehen den Klemmvorrichtungen in einer Bearbeitungslage ein in Richtung der Drehachse verlagerbares und unabhängig vom Trennwerkzeug radial zur Dreh achse anstellbares Markierwerkzeug angeordnet ist. Im einfachsten Fall kann das Markierwerkezug einen Markierungsstift zur farblichen Kennzeichnung der zur markierenden Schlauchstellen umfassen. So that both the marking of the hose section to be peeled off and the marking of the respective insertion depths for fittings attached to the assembled hose do not have to be carried out in a separate manual work step before the actual machining process and a compact construction of the machine is nevertheless achieved, it is recommended that that between see the clamping devices in a processing position a displaceable in the direction of the axis of rotation and independently of the cutting tool radially adjustable to the axis of rotation marking tool is arranged. In the simplest case, the marking tool train can comprise a marking pen for color coding the hose locations to be marked.
Die Erfindung bezieht sich auch auf ein Verfahren zum Schälen und Trennen von mehreren Schlauchlagen aufweisenden Hydraulikschläuchen. Dabei wird der Hyd raulikschlauch zunächst in zwei bezüglich der Schlauchlängsachse voneinander beabstandeten Klemmvorrichtungen festgelegt, wonach der Mantel bzw. die Deck lage des Hydraulikschlauches in einem vorgegebenen Konfektionsabschnitt mit Hilfe eines Schälwerkzeuges bis zur Druckträgerlage geschält wird, bevor diese mit dem Trennwerkzeug durchtrennt wird. Anschließend wird die Schlauchseele mit Hilfe eines Abstichwerkzeuges durchstochen und abgetrennt. The invention also relates to a method for peeling and separating hydraulic hoses having a plurality of hose layers. The hydraulic hose is first set in two clamping devices spaced apart from one another with respect to the longitudinal axis of the hose, after which the jacket or the cover layer of the hydraulic hose is peeled in a predetermined assembly section with the help of a peeling tool up to the pressure carrier layer before it is severed with the separating tool. The tube core is then pierced with a tapping tool and separated.
Nach deren Fertigung können konfektionierbare Schläuche an ihren bearbeiteten Schlauchenden vermessen werden, um für die Qualitätssicherung relevante Pa rameter wie beispielsweise Innen- und Außendurchmesser der Schlauchenden zu ermitteln. Um in diesem Zusammenhang einen besonders raschen und dennoch zuverlässigen Messvorgang zu ermöglichen, wird vorgeschlagen, dass nach dem Abtrennen der Schlauchseele eines der entstehenden Hydraulikschlauchstücke in einer der beiden Klemmvorrichtungen festgelegt bleibt und der Innen- und Außen durchmesser des festgelegten Hydraulikschlauchstückes an seiner Trennstelle mittels einer Messeinrichtung bestimmt wird. Nach erfolgtem Schäl- und Trenn vorgang des Schlauches durch eine erfindungsgemäße Vorrichtung, wodurch zwei idente, an einer Normalebene der Schlauchlängsachse gespiegelte Schlauchstü cke mit konfektionierbarem Schlauchende gebildet wurden, kann somit lediglich eines der beiden Schlauchstücke in der ihm zugewiesenen Klemmvorrichtung festgelegt bleiben und vermessen werden, während das andere Schlauchstück bereits aus der jeweils anderen Klemmvorrichtung herausgenommen werden kann. Die Vermessung der Schlauchendendurchmesser kann beispielsweise über eine Messnadel erfolgen. Dadurch, dass die beiden Schlauchstücke bzw. deren konfektionierbare Schlauchenden aufgrund der vorangegangen Bearbeitung durch die erfindungsgemäße Vorrichtung im Wesentlichen identisch ausgebildet sind, da beide Schlauchenden demselben Schlauchabschnitt entstammen, entsprechen die Durchmesser des vermessenen Schlauchendes zwangsläufig auch denen des nicht vermessenen Schlauchendes. Zufolge dieser Maßnahmen können somit be reits in einem Messvorgang für die Qualitätssicherung relevante Parameter wie Schlauchendendurchmesser für zwei konfektionierbare Schlauchenden bestimmt werden. After their manufacture, ready-to-use hoses can be measured on their processed hose ends in order to determine parameters relevant for quality assurance, such as the inside and outside diameter of the hose ends. In order to enable a particularly quick and yet reliable measuring process in this context, it is proposed that after the hose core has been disconnected, one of the hydraulic hose sections that is created remains fixed in one of the two clamping devices and the inside and outside diameter of the defined hydraulic hose section at its separation point by means of a measuring device is determined. After the peeling and separation process of the hose has been carried out by a device according to the invention, whereby two identical hose pieces with a hose end that can be assembled and mirrored on a normal plane of the longitudinal axis of the hose have been formed, only one of the two hose pieces can thus remain fixed and measured in the clamping device assigned to it, while the other piece of hose can already be removed from the other clamping device. The measurement of the hose end diameters can take place, for example, using a measuring needle. Characterized in that the two hose pieces or their ready-to-assemble hose ends due to the previous processing the device according to the invention are essentially identical, since both hose ends originate from the same hose section, the diameters of the measured hose end inevitably correspond to those of the hose end not measured. As a result of these measures, parameters relevant to quality assurance, such as hose end diameters for two hose ends that can be assembled, can already be determined in one measurement process.

Wege zur Ausführung der Erfindung Ways of Carrying Out the Invention
Eine erfindungsgemäße Vorrichtung weist eine um eine Drehachse 1 gelagerte Bearbeitungseinheit 2 auf, die ein radial zur Drehachse 1 anstellbares Trennwerk zeug 3 umfasst. Ein zu bearbeitender Hydraulikschlauch 4 wird über zwei in Rich tung der Drehachse 1 voneinander beabstandete Klemmvorrichtungen 5 festge legt. Wie dies in Fig. 1 gut zu erkennen ist, weist die Vorrichtung ein zwischen den Klemmvorrichtungen 5 in einer Bearbeitungslage in Richtung der Drehachse 1 ver lagerbares und unabhängig vom Trennwerkzeug 3 radial zur Drehachse 1 anstell bares Schälwerkzeug 6 auf. Während eines Schäl- und Trennvorgangs rotiert das Schälwerkzeug 6 bzw. das Trennwerkzeug 3 um den festgeklemmten Hydraulik schlauch 4. Es können überdies ein Abstichwerkzeug 7 zum Durchtrennen der Schlauchseele sowie ein Markierwerkzeug 8 zum Festlegen des Start- und Endpunktes der abzu schälenden Länge bzw. zum Festlegen der Einstecktiefe für nachträglich aufge steckte Armaturen vorgesehen sein. Das Abstichwerkzeug 7 und das Markier werkzeug 8 können dabei ebenfalls zwischen den Klemmvorrichtungen 5 in einer Bearbeitungslage in Richtung der Drehachse 1 verlagerbar und unabhängig vom Trennwerkzeug 3 radial zur Drehachse 1 anstellbar angeordnet sein. A device according to the invention has a processing unit 2 mounted about an axis of rotation 1, which comprises a separating tool 3 which can be set radially to the axis of rotation 1. A hydraulic hose 4 to be machined is festge via two spaced-apart clamping devices 5 in the direction of the rotational axis 1. As can be clearly seen in Fig. 1, the device has a ver between the clamping devices 5 in a processing position in the direction of the axis of rotation 1 and independently of the separating tool 3 radially to the axis of rotation 1 adjustable peeling tool 6. During a peeling and separating process, the peeling tool 6 or the separating tool 3 rotates around the clamped hydraulic hose 4. There can also be a tapping tool 7 for severing the hose core and a marking tool 8 for determining the start and end point of the length to be peeled off or for defining the insertion depth for subsequently fitted fittings. The tapping tool 7 and the marking tool 8 can also be displaceable between the clamping devices 5 in a processing position in the direction of the axis of rotation 1 and can be arranged independently of the cutting tool 3 radially to the axis of rotation 1.
Die Zustellbewegung des Trennwerkzeugs 3 kann grundsätzlich mit unterschied lichsten Zustelltriebkonzepten realisiert werden. Der Zustellmechanismus der in den Fig. 1 und 2 gezeigten Ausführungsform weist beispielsweise Zustellscheiben 9, 10 auf, die über einen Um lenkhebel 11 mit dem Trennwerkzeug 3 antriebsver bunden sind. Der Umlenkhebel 11 steht über eine Anlaufrolle 12 in Kontakt mit der Zustellscheibe 9, sodass eine über eine Betätigungskurbel 13 initiierte Verlage rungsbewegung der Zustellscheiben 9, 10 in Richtung der Drehachse 1 mittels des Umlenkhebels 11 in eine radial zur Drehachse 1 verlaufende Anstellbewegung des Trennwerkzeugs 3 übersetzt wird. The infeed movement of the separating tool 3 can in principle be realized with a wide variety of infeed drive concepts. The feed mechanism of the embodiment shown in FIGS. 1 and 2 has, for example, feed disks 9, 10, which are connected to a drive lever 11 with the separating tool 3 antriebsver. The bell crank 11 is in contact with the feed disc 9 via a thrust roller 12, so that a displacement movement initiated by an actuating crank 13 translates the feed discs 9, 10 in the direction of the axis of rotation 1 by means of the bell crank 11 into a radial movement of the axis of rotation 1 of the cutting tool 3 becomes.
Um besonders günstige Schnittbedingungen zu ermöglichen, kann die Bearbei tungseinheit 2 eine Bandsäge als Trennwerkzeug 3 aufweisen, wie dies den Fig. 1 und 2 zu entnehmen ist. Das umlaufende Sägeband 14 kann über Umlenkrollen 15, 16 geführt bzw. angetrieben werden, wobei die Umlenkrollenachsen parallel zur Drehachse 1 ausgerichtet sein können, um eine kompakte Bauweise der Vor richtung sowie eine geringere Unwucht sicherzustellen. Damit ein sauberer Schnitt ermöglicht wird, empfiehlt es sich, das Sägeband 14 über Führungsrollen 17 zu führen, sodass das Sägeband 14 im Wirkabschnitt 18 der Bandsäge aus seiner Umlauflage so ausgelenkt ist, dass die Sägebandflächennormale parallel zur Drehachse verläuft. Dies bedeutet, dass die an die Schneidkante bzw. den der Schneidkante gegenüberliegenden Bandrücken anschließenden Bandflächen in der Umlauflage des Sägebandes 14 eine im Wesentlichen radial zur Drehachse verlaufende Flächennormale aufweisen und nur im Wirkabschnitt 18 der Bandsä ge das Sägeband 14 beispielsweise über Führungsrollen 17 um etwa 90° so um gelenkt wird, dass die Bandflächen in einer Normalebene der Drehachse 1 verlau- fen, sodass die Schneidkante radial in Richtung der Drehachse 1 an einen Hyd raulikschlauch 4 angestellt werden kann In order to enable particularly favorable cutting conditions, the processing unit 2 can have a band saw as a cutting tool 3, as can be seen in FIGS. 1 and 2. The rotating saw band 14 can be guided or driven via deflection rollers 15, 16, wherein the deflection roller axes can be aligned parallel to the axis of rotation 1 in order to ensure a compact design of the device and less imbalance. So that a clean cut is made possible, it is advisable to guide the saw band 14 over guide rollers 17, so that the saw band 14 is deflected from its circulating position in the effective section 18 of the band saw in such a way that the saw band surface normal runs parallel to the axis of rotation. This means that the band surfaces adjoining the cutting edge or the band back opposite the cutting edge in the circumferential position of the saw band 14 have a surface normal which extends essentially radially to the axis of rotation and the saw band 14 only in the active section 18 of the band saw, for example via guide rollers 17 by approximately 90 ° is deflected in such a way that the belt surfaces run in a normal plane of the axis of rotation 1 fen, so that the cutting edge can be placed radially in the direction of the axis of rotation 1 on a hydraulic hose 4
Wie aus Fig. 2 ersichtlich ist, kann die Bearbeitungseinheit 2 um die Drehachse 1 rotierbar an einem Träger 19 gelagert sein. In der dort gezeigten Ausführungsform treibt beispielsweise ein Rotationsantrieb 20 über ein Zahnrad 21 eine den Grund körper der Bearbeitungseinheit 2 bildende Abtriebshohlwelle 22 an. As can be seen from FIG. 2, the processing unit 2 can be mounted on a carrier 19 so as to be rotatable about the axis of rotation 1. In the embodiment shown there, for example, a rotary drive 20 drives a hollow output shaft 22 forming the basic body of the processing unit 2 via a gear 21.
Fig. 3 zeigt beispielhaft eine Ausführungsform einer erfindungsgemäßen Klemm vorrichtung 5. Die Klemmvorrichtung 5 weist dabei ein Schneckenrad 23 auf, das mehrere innenumfangsseitig angeordnete, sowie zum Schneckenradmittelpunkt in Abhängigkeit der Schneckenradstellung radial verlagerbare Klemmelemente 24 zum Festklemmen des Hydraulikschlauches 4 umfasst. Die Schneckenradstellung kann beispielsweise über eine mit dem Schneckenrad 23 in Eingriff stehende Schneckenwelle 25 verändert werden. Fig. 3 shows an example of an embodiment of a clamping device 5 according to the invention. The clamping device 5 has a worm wheel 23 which comprises a plurality of clamping elements 24 arranged on the inner circumference side and radially displaceable to the worm wheel center depending on the worm wheel position for clamping the hydraulic hose 4. The worm wheel position can be changed, for example, via a worm shaft 25 which is in engagement with the worm wheel 23.
