Description

Technisches GebietTechnical area
Die Erfindung betrifft eine Lanze, insbesondere eine Rotationslanze, zum Entgraten und/oder Reinigen von Werkstücken. Speziell betrifft die Erfindung das Gebiet der Hochdruck-Rotationslanzen, die zum Entgraten von Kanälen mit Querbohrungen und/oder Öffnungen in Werkstücken dienen.The invention relates to a lance, in particular a rotary lance, for deburring and / or cleaning workpieces. Specifically, the invention relates to the field of high pressure rotary lances used for deburring channels having transverse bores and / or openings in workpieces.
Bei der Ausgestaltung einer Lanze zum Entgraten von Werkstücken ist es denkbar, dass mehrere Schlitze in einer Wandung der Lanze vorgesehen sind, die sich zusammen genommen über den gesamten Umfang der Rotati- onslanze erstrecken. Diese Ausgestaltung hat den Nachteil, dass eine Entgratungswirkung in bestimmten Anwendungsfällen nicht ausreichend ist.In the embodiment of a lance for deburring workpieces, it is conceivable that a plurality of slots are provided in a wall of the lance, which taken together extend over the entire circumference of the rotation lance. This embodiment has the disadvantage that a deburring effect is not sufficient in certain applications.
Darstellung der ErfindungPresentation of the invention
Eine Aufgabe der Erfindung ist es, eine Lanze mit einer verbesserten Wirkungsweise zu schaffen. Speziell ist es eine Aufgabe der Erfindung, eine Lanze zu schaffen, die eine verbesserte Entgratungs- und/oder Reinigungswirkung aufweist.An object of the invention is to provide a lance with an improved mode of action. In particular, it is an object of the invention to provide a lance having an improved deburring and / or cleaning action.
Diese Aufgaben werden durch eine erfindungsgemäße Lanze mit den Merkmalen des Anspruchs 1 gelöst.These objects are achieved by a lance according to the invention having the features of claim 1.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen der im Anspruch 1 angegebenen Lanze möglich. Speziell beim Entgraten von Kanälen in Werkstücken, die aus Materialien gebildet sind, bei denen sich an Querbohrungen, Öffnungen oder anderen Verschneidungsstellen Grate bilden, ist die vollständige oder teilweise Entfernung solcher Grate in der Regel erforderlich, um ein späteres Ablösen eines Grats oder zumindest eines Teils eines Grats zu vermeiden. Hierbei kann in Abhängigkeit von dem jeweiligen Anwendungsfall auch ein teilweises Entfernen von Graten ausreichen, wenn der verbleibende Teil des Grats stabil genug ist, um sich im späteren Einsatz nicht mehr zu lösen. In vorteilhafter Weise kann beim Entgraten mit der Lanze ein zumindest teilweise zu entfernender Grat in einem günstigen Winkel mit einer Fluidströmung getroffen werden, wobei der Impuls der Strömung ausreichend ist, um den Grad vom Werkstück zu trennen. Hierbei kann zum einen vermieden werden, dass der Winkel zu steil ist, und zum anderen kann vermieden werden, dass nur eine sehr schmale Seite des Grates von dem Medium getroffen wird. In vor- teilhafter Weise kann ein unter hohem Druck stehendes Medium eine erfindungsgemäße Fluidströmung bilden, wobei das Medium beispielsweise unter einem Druck von mehr als 30 MPa (300 bar) steht.The measures listed in the dependent claims advantageous refinements of the claim 1 lance are possible. Specifically, when deburring channels in workpieces formed from materials that form burrs at cross holes, apertures, or other points of intersection, complete or partial removal of such burrs is typically required to later dislodge a burr or at least a portion to avoid a ridge. In this case, depending on the particular application, a partial removal of burrs are sufficient if the remaining part of the ridge is stable enough not to dissolve in later use. Advantageously, when deburring with the lance, an at least partially removed burr may be struck at a favorable angle with fluid flow, the momentum of the flow being sufficient to separate the degree from the workpiece. This can be avoided on the one hand that the angle is too steep, and on the other hand can be avoided that only a very narrow side of the ridge is hit by the medium. Advantageously, a medium under high pressure can form a fluid flow according to the invention, wherein the medium is, for example, under a pressure of more than 30 MPa (300 bar).
Vorteilhaft ist es, wenn an dem Düsenabschnitt zumindest eine (bezogen auf eine Vorschubrichtung der Lanze und/oder eine Drehrichtung eines Lanzenabschnitts) vorwärts und/oder eine rückwärts gerichtete Düse vorgesehen ist, über die das zu dem Düsenabschnitt führbare Medium strahlförmig abgebbar ist. Durch eine vorwärts und/oder eine rückwärts gerichtete Düse kann zum einen ein vorteilhafter Strahl gebildet werden, der zum Abtragen oder zum Ablösen des Grates eine hohe Wirksamkeit beim Auftreffen erzielt. Zum anderen kann beispielsweise bei Graten an Querbohrungen oder Öffnungen ein seitliches Anstrahlen des Grats erreicht werden, so dass der Grat von dem Strahl an seiner Seitenfläche getroffen wird, wodurch eine große Ablösekraft entsteht. Vorteilhaft ist es, wenn an dem Düsenabschnitt zumindest eine seitwärts gerichtete Düse vorgesehen ist, über die das zu dem Düsenabschnitt führbare Medium strahlförmig abgebbar ist, und/oder dass an dem Düsenabschnitt zumindest eine tangential gerichtete Düse vorgesehen ist, über die das zu dem Düsenabschnitt führbare Medium strahlförmig abgebbar ist, und/oder dass eine weitere tangential gerichtete Düse vorgesehen ist, über die das zu dem Düsenabschnitt führbare Medium strahlförmig abgebbar ist, und dass die weitere tangential gerichtete Düse bezüglich einer Drehrichtung entgegengesetzt zu der tangential gerichteten Düse ausgerichtet ist. Seitwärts gerichtete Düsen weisen bevorzugt jeweils eine Auslassrichtung auf, die quer zur Vorschubrichtung der Lanze und/oder quer zu einer Lanzenachse orientiert ist. Tangential gerichtete Düsen weisen bevorzugt jeweils eine Auslassrichtung auf, die in einem spitzen Winkel zu einer zylindrischen Um- fangsfläche der Lanze und in einer Fläche senkrecht zu einer Lanzenachse orientiert ist. Durch eine seitwärts oder tangential gerichtete Düse hindurch kann das Medium in einem Strahl abgegeben werden, der beim Auftreffen eine hohe Entgratungswirkung hat. Außerdem kann der Strahl in einer vorteilhaften Richtung (entsprechend seiner Auslassrichtung) auf den Grat gerichtet werden. Speziell durch eine tangential gerichtete Düse ist ein vorteil- haftes Entgraten eines Kanals, insbesondere eines durch Bohrungen gebildeten Kanals, möglich. Hierbei kann ein Querschnitt, insbesondere ein kreisförmiger Querschnitt, des Düsenabschnitts der Lanze an den Querschnitt des Kanals angepasst sein, so dass das aus der tangential gerichteten Düse strahlförmig und tangential austretende Medium von der Kanalwand in Rich- tung auf den Grat abgelenkt wird und eine vorteilhafte Entgratung erfolgt.It is advantageous if at least one (with respect to a feed direction of the lance and / or a direction of rotation of a lance portion) forward and / or a rearwardly directed nozzle is provided on the nozzle portion, over which the feasible to the nozzle portion medium can be emitted beam-shaped. By means of a forward and / or a backward nozzle, on the one hand, an advantageous jet can be formed, which achieves a high degree of effectiveness on impact for removing or detaching the burr. On the other hand, for example, in the case of burrs on transverse bores or openings, lateral irradiation of the burr can be achieved, so that the burr is hit by the beam on its side surface, resulting in a large detaching force. It is advantageous if at least one laterally directed nozzle is provided on the nozzle section, via which the medium which can be guided to the nozzle section can be emitted in a jet-like manner, and / or at least one tangentially directed nozzle is provided on the nozzle section via which the nozzle can be guided to the nozzle section Medium jet-shaped can be issued, and / or that a further tangentially directed nozzle is provided, via which the feasible to the nozzle portion medium jet is deliverable, and that the further tangentially directed nozzle is aligned with respect to a direction of rotation opposite to the tangentially directed nozzle. Side-facing nozzles preferably each have an outlet direction, which is oriented transversely to the feed direction of the lance and / or transversely to a lance axis. Tangentially directed nozzles preferably each have an outlet direction which is oriented at an acute angle to a cylindrical circumferential surface of the lance and in a surface perpendicular to a lance axis. Through a laterally or tangentially directed nozzle, the medium can be emitted in a jet, which has a high Entgratungswirkung when hitting. In addition, the beam can be directed to the ridge in an advantageous direction (according to its outlet direction). Especially through a tangentially directed nozzle, an advantageous deburring of a channel, in particular of a channel formed by bores, is possible. In this case, a cross section, in particular a circular cross section, of the nozzle section of the lance can be adapted to the cross section of the channel, so that the medium issuing from the tangentially directed nozzle in a jet-like and tangential direction is deflected by the channel wall in the direction of the ridge and an advantageous Deburring takes place.
Vorteilhaft ist es, wenn zumindest eine schräg gestellte vor- oder rückwärts gerichtete Düse vorgesehen ist, die zumindest teilweise entgegen der seitlichen Ausrichtung zumindest einer seitwärts oder tangential gerichteten Dü- se ausgerichtet ist. Hierdurch kann eine speziell bei längeren Lanzen durch die seitwärts oder tangential gerichteten Düsen entstehende Querkraft zu- mindest teilweise kompensiert werden, wodurch ein unerwünschtes Auslenken der Lanze verringert oder verhindert werden kann.It is advantageous if at least one inclined forward or backward nozzle is provided, which is at least partially aligned against the lateral orientation of at least one sideways or tangentially directed nozzle. As a result, a transverse force, which is generated in particular by the laterally or tangentially directed nozzles in the case of longer lances, can be increased. At least partially compensated, whereby an undesirable deflection of the lance can be reduced or prevented.
Vorteilhaft ist es, wenn die tangential gerichtete Düse mit einer Auslassrich- tung zumindest im Wesentlichen in einer Umfangsrichtung ausgerichtet ist. In Bezug auf eine Außenwand des Düsenabschnitts tritt das Medium dadurch möglichst flach an der Außenwand aus der Düse aus, so dass sich ein im Wesentlichen in der Umfangsrichtung ausgerichteter Strahl ergibt. Ein Winkel zur Außenwand der Lanze beträgt vorzugsweise weniger als 30°. Hierdurch kann der Strahl in einem günstigen Winkel auf den Grat gerichtet werden, wobei der Strahl insbesondere seitlich an den Grat trifft und somit nicht nur die gegebenenfalls sehr schmale Seite des Grates getroffen wird. Somit kann die Wirkung des auf den Grat auftreffenden Strahls weiter verbessert werden.It is advantageous if the tangentially directed nozzle is aligned with an outlet direction at least substantially in a circumferential direction. With respect to an outer wall of the nozzle portion, the medium thereby exits the nozzle as flat as possible on the outer wall, so that a substantially aligned in the circumferential direction of the jet results. An angle to the outer wall of the lance is preferably less than 30 °. In this way, the beam can be directed at a favorable angle to the ridge, the beam in particular hits the ridge laterally and thus not only the optionally very narrow side of the ridge is hit. Thus, the effect of the jet incident on the burr can be further improved.
Vorteilhaft ist es, wenn in dem Düsenabschnitt zumindest ein Stauraum für die Düse ausgebildet ist. Durch den Stauraum kann der Wirkungsgrad der in dem Düsenabschnitt vorgesehenen Düsen weiter verbessert werden. Speziell kann bei einem schnell strömenden Fluid eine vorteilhafte Erhöhung des Wirkungsgrads erzielt werden.It is advantageous if at least one storage space for the nozzle is formed in the nozzle section. By the storage space, the efficiency of the nozzles provided in the nozzle section can be further improved. Specifically, in a rapidly flowing fluid, an advantageous increase in the efficiency can be achieved.
Vorteilhaft ist es, wenn der Stauraum durch zumindest eine Staufläche begrenzt ist, die zumindest im Wesentlichen entgegen einer Strömungsrichtung des durch die Leitung führbaren Mediums orientiert ist und/oder wenn sich der Stauraum zumindest teilweise in eine Wandung des Düsenabschnitts erstreckt. Durch eine entgegen der Strömungsrichtung orientierte Staufläche kann eine vorteilhafte Stauung des Fluids für die an den Stauraum angrenzenden Düsen im Düsenabschnitt erzielt werden. Durch die Erstreckung des Stauraums in die Wand des Düsenabschnitts kann bei- spielsweise für tangential gerichtete Düsen, die in den Stauraum münden, eine weitere Verbesserung des Wirkungsgrads erzielt werden. Vorteilhaft ist es, wenn in dem Düsenabschnitt ein Einlauf für die Düse ausgebildet ist. Solch ein Einlauf ist speziell für eine vor- oder rückwärts gerichtete Düse von Vorteil, um die Wirkung weiter zu verbessern. Dies kann in vorteilhafter Weise mit einem Stauraum für seitlich oder tangential gerichtete Düsen kombiniert werden.It is advantageous if the storage space is delimited by at least one storage area which is oriented at least substantially counter to a flow direction of the medium which can be guided through the conduit and / or if the storage space at least partially extends into a wall of the nozzle portion. By means of a storage area oriented counter to the flow direction, an advantageous stowage of the fluid for the nozzles adjacent to the storage space in the nozzle section can be achieved. By extending the storage space into the wall of the nozzle section, a further improvement in the efficiency can be achieved, for example, for tangentially directed nozzles which open into the storage space. It is advantageous if an inlet for the nozzle is formed in the nozzle section. Such an inlet is especially advantageous for a forward or reverse nozzle to further enhance the effect. This can be advantageously combined with a storage space for laterally or tangentially directed nozzles.
Vorteilhaft ist es, wenn der Einlauf für die Düse als zumindest abschnittsweise konischer Einlauf ausgestaltet ist und/oder dass der Einlauf für eine vor- wärts gerichtete Düse vorgesehen ist. Sowohl die konische Ausgestaltung des Einlaufs als auch die Ausgestaltung der Düse als vorwärts gerichtete Düse sind strömungstechnisch von Vorteil, da Verwirbelungen oder Ablösungen der Strömung verhindert oder zumindest verringert werden können.It is advantageous if the inlet for the nozzle is designed as at least partially conical inlet and / or that the inlet is provided for a forwardly directed nozzle. Both the conical design of the inlet and the design of the nozzle as a forward nozzle are aerodynamically advantageous because turbulence or separation of the flow can be prevented or at least reduced.
Vorteilhaft ist es, wenn der Düsenabschnitt an einer Spitze der Lanze vorgesehen ist. Hierdurch ist eine vorteilhafte Anordnung mehrerer Düsen an dem Düsenabschnitt möglich. Außerdem kann eine größere Anzahl von Düsen auch bei einer relativ kleinen Spitze realisiert werden. Vorteilhaft ist dabei auch, dass eine vorwärts gerichtete Düse zumindest näherungsweise an einer Längsachse des Düsenabschnitts ausgerichtet ist. Hierdurch kann beim Einführen beziehungsweise Durchführen der Lanze durch einen Kanal oder dergleichen ein in Vorwärtsrichtung gerichteter Strahl erzeugt werden. Speziell in Kombination mit seitlich oder tangential gerichteten Düsen können bestehende Grate zum Entgraten aus unterschiedlichen Richtungen getroffen werden, so dass eine weitgehende Entgratung möglich ist.It is advantageous if the nozzle section is provided at a tip of the lance. As a result, an advantageous arrangement of a plurality of nozzles on the nozzle portion is possible. In addition, a larger number of nozzles can be realized even at a relatively small peak. It is also advantageous that a forward nozzle is oriented at least approximately on a longitudinal axis of the nozzle section. As a result, during the introduction or passage of the lance through a channel or the like, a beam directed in the forward direction can be generated. Especially in combination with laterally or tangentially directed nozzles, existing burrs can be made for deburring from different directions, so that extensive deburring is possible.
Vorteilhaft ist es, wenn zumindest der Düsenabschnitt der Lanze im Betrieb und/oder entgegen einer Umfangsrichtung des Düsenabschnitts rotierbar ist. Hierdurch ergibt sich zum einen eine vorteilhafte Ausnutzung der vorgese- henen Düsen. Außerdem kann bei einer Ausgestaltung, in der entgegengesetzt zueinander orientierte tangential gerichtete Düsen vorgesehen sind, ein Grat zunächst von einer Richtung und dann im weitergedrehten Zustand der Lanze von einer anderen Richtung bearbeitet werden. Hierdurch wird der Grat sozusagen hin und her gebogen, so dass der Grat abbricht und somit entfernt wird.It is advantageous if at least the nozzle section of the lance is rotatable during operation and / or counter to a circumferential direction of the nozzle section. On the one hand, this results in an advantageous utilization of the provided nozzles. In addition, in an embodiment in which oppositely oriented tangentially directed nozzles are provided, a burr is first processed from one direction and then in the further rotated state of the lance from another direction. This bends the burr back and forth, so to speak, so that the burr breaks off and is thus removed.
Vorteilhaft ist es, wenn die Düse durch zumindest eine in dem Düsenabschnitt ausgebildete Düsenbohrung ausgestaltet ist. Hierdurch ist eine kompakte Ausgestaltung des Düsenabschnitts der Lanze möglich. Außerdem wird eine hohe mechanische Festigkeit der Düse ermöglicht.It is advantageous if the nozzle is configured by at least one nozzle bore formed in the nozzle section. As a result, a compact configuration of the nozzle portion of the lance is possible. In addition, a high mechanical strength of the nozzle is possible.
Vorteilhaft ist es schließlich, wenn an einem Düsenabschnitt einer erfindungsgemäßen Lanze wenigstens eine erste, näherungsweise in Richtung der Längsachse der Lanze orientierte Düse sowie wenigstens eine zweite, näherungsweise quer zur Längsachse der Lanze orientierte Düse gebildet sind, durch die ein bevorzugt inkompressibles Medium gegen das Werkstück gespritzt werden kann, wobei das Werkstück und der Düsenabschnitt relativ zueinander in Richtung der Längsachse der Lanze verstellbar und relativ zueinander um die Längsachse verdrehbar ausgeführt sind.Finally, it is advantageous if at least one first nozzle oriented approximately in the direction of the longitudinal axis of the lance and at least one second nozzle oriented approximately transversely to the longitudinal axis of the lance are formed on a nozzle section of a lance according to the invention, through which a preferably incompressible medium bears against the workpiece can be injected, wherein the workpiece and the nozzle portion are designed relative to each other in the direction of the longitudinal axis of the lance adjustable and rotatable relative to each other about the longitudinal axis.
Ferner ist es Aufgabe der Erfindung, ein Behandlungsverfahren zum Entgraten und/oder zur Reinigung von Werkstücken zur Verfügung zu stellen.It is another object of the invention to provide a treatment method for deburring and / or for cleaning workpieces available.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 14 gelöst.This object is achieved by a method having the features of claim 14.
Dabei weist eine näherungsweise in Richtung einer Längsachse orientierten Düse erfindungsgemäß eine Auslassrichtung auf, die einen Winkel von bis zu 30° mit der Längsachse der Lanze einschließt. Dabei weist eine näherungsweise quer zu einer Längsachse der Lanze orientierte Düse erfin- dungsgemäß eine Auslassrichtung auf, die einen Winkel von mindestens 60° mit der Längsachse der Lanze einschließt. Das erfindungsgemäße Ver- fahren weist dabei mehrere Verfahrensschritte auf, die in beliebiger Reihenfolge sowie teils oder vollständig zeitgleich ausführbar sind.In this case, an approximately oriented in the direction of a longitudinal axis nozzle according to the invention an outlet direction, which forms an angle of up to 30 ° with the longitudinal axis of the lance. In this case, an orifice oriented approximately transverse to a longitudinal axis of the lance according to the invention has an outlet direction which encloses an angle of at least 60 ° with the longitudinal axis of the lance. The inventive In this case, driving has a plurality of method steps which can be carried out in any desired sequence as well as partially or completely at the same time.

Bevorzugte Ausführungsformen der ErfindungPreferred embodiments of the invention
Fig. 1 zeigt eine Lanze 1 entsprechend einem Ausführungsbeispiel und ein Werkstück 2 in einer auszugsweisen, schematischen Schnittdarstellung. Die Lanze 1 des Ausführungsbeispiels dient bevorzugt zum Entgraten des Werkstücks 2, indem mit Hilfe der Lanze gezielt eine Fluidströmung mit ei- nem einstellbaren Strömungsimpuls gegen Abschnitte des Werkstücks 2 gerichtet werden kann. Hierbei wird beispielsweise ein zwischen einem Ka- nal 3 und einer Querbohrung 4 vorgesehener Grat 5 ganz oder teilweise mittels der Fluidströmung vom Werkstück abgetrennt und entfernt. Die erfindungsgemäße Lanze 1 eignet sich jedoch auch für andere Anwendungsfälle und dient insbesondere auch zum Reinigen von Werkstücken 2, indem am Werkstück haftende Partikel mittels einer Fluidströmung abgelöst und abtransportiert werden. In bevorzugter Weise wird die Fluidströmung mit einem oberhalb des Umgebungsdruckes liegenden Arbeitsdruck (z. B. mit einem Arbeitsdruck von 100 bar und mehr) gegen das Werkstück gerichtet. In weiter bevorzugter Weise wird das Fluid mit einem rasch in einer Frequenz von mehr als 1 Hz wechselnden Arbeitsdruck gegen das Werkstück gerichtet. In weiter bevorzugter Weise ist die Lanze 1 als Rotationslanze 1 ausgestaltet, so dass ihr Düsenabschnitt bzw. ihr Lanzenkopf und ggf. weitere Abschnitte der Lanze mit einer Frequenz von mehr als 1 Hz um eine Lanzenachse rotieren, so dass die Fluidströmung im raschen Wechsel auf unterschiedliche Abschnitte des Werkstücks gelangt. Eine solche Ausführung ist selbstverständlich mit den weiterhin genannten Optionen kombinierbar.Fig. 1 shows a lance 1 according to an embodiment and a workpiece 2 in a partial, schematic sectional view. The lance 1 of the exemplary embodiment is preferably used for deburring the workpiece 2, in that a fluid flow with an adjustable flow pulse can be directed against sections of the workpiece 2 in a targeted manner with the aid of the lance. For example, one between a cable nal 3 and a transverse bore 4 provided ridge 5 completely or partially separated by means of the fluid flow from the workpiece and removed. However, the lance 1 according to the invention is also suitable for other applications and is also used in particular for cleaning workpieces 2 by detaching and removing particles adhering to the workpiece by means of a fluid flow. In a preferred manner, the fluid flow is directed against the workpiece at a working pressure above the ambient pressure (eg with a working pressure of 100 bar and more). More preferably, the fluid is directed against the workpiece at a working pressure rapidly changing at a frequency greater than 1 Hz. In a further preferred manner, the lance 1 is designed as a rotary lance 1, so that its nozzle section or lance head and possibly further portions of the lance rotate at a frequency of more than 1 Hz about a lance axis, so that the fluid flow in rapid change to different Sections of the workpiece passes. Such an embodiment can of course be combined with the options mentioned further.
In einem weiteren modifizierten Ausführungsbeispiel ist das Werkstück auf einem beweglich angeordneten Träger rotierbar gelagert, so dass das Werk- stück gegenüber der Lanze mit einer ggf. wechselnden Frequenz verdreht werden kann. Die Lanze kann dann auch fest montiert angeordnet sein. Optional ist vorsehbar, dass Werkstück und Lanzenkopf jeweils unabhängig voneinander rotierbar, ggf. gegenläufig rotierbar ausgeführt sind.In a further modified embodiment, the workpiece is rotatably mounted on a movably arranged carrier, so that the workpiece can be rotated relative to the lance with a possibly changing frequency. The lance can then be arranged fixedly mounted. Optionally, it can be provided that the workpiece and the lance head are each rotatable independently of one another, if necessary, are designed to rotate in opposite directions.
Zur Herstellung einer geeigneten Fluidströmung ist ein flüssiges oder gasförmiges Medium vorgesehen, dem ein hoher Strömungsimpuls in Form hoher Strömungsgeschwindigkeit und/oder hohen Arbeitsdrucks mitgegeben werden kann.To produce a suitable fluid flow, a liquid or gaseous medium is provided, to which a high flow impulse in the form of high flow velocity and / or high working pressure can be given.
Die Lanze 1 des Ausführungsbeispiels weist einen rohrförmigen Grundkörper 6 und einen Düsenabschnitt 7 auf. Der rohrförmige Grundkörper 6 ist in der Fig. 1 abschnittsweise dargestellt. Die Länge des rohrförmigen Grundkörpers 6 ist so vorgegeben, dass in dem Werkstück 2 vorgesehene Kanäle, insbesondere der Kanal 3, durchfahren werden können. Der Düsenabschnitt 7 ist in diesem Ausführungsbeispiel als Kopfabschnitt 7 ausgestaltet. Durch den Kopfabschnitt 7 ist eine Spitze 8 der Lanze 1 gebildet. Der Kanal 3 weist einen kreisförmigen Querschnitt 9 auf. Außerdem weist der Kanal 3 eine Achse 10 auf. Der Grundkörper 6 der Lanze 1 weist eine Achse 11 auf. Beim Einführen der Lanze 1 in den Kanal 3 wird die Achse 11 des Grundkörpers 6 der Lanze 1 an der Achse 10 des Kanals 3 ausgerichtet. Hierbei liegt die Achse 11 des Grundkörpers 6 der Lanze 1 vorzugsweise zumindest näherungsweise auf der Achse 10 des Kanals 3. Die Lanze 1 wird in einer Vorschubrichtung in den Kanal 3 eingeführt. Hierbei ist es auch möglich, dass die Lanze 1 beim Durchfahren des Kanals 3 abschnittsweise hin und her bewegt wird. Das heißt, die Lanze 1 kann beim Durchfahren des Kanals 3 auch teilweise entgegen der Vorschubrichtung 12 bewegt werden.The lance 1 of the embodiment has a tubular base body 6 and a nozzle portion 7. The tubular base body 6 is in Fig. 1 shown in sections. The length of the tubular base body 6 is predetermined so that in the workpiece 2 provided channels, in particular the channel 3, can be passed. The nozzle section 7 is designed in this embodiment as a head section 7. Through the head portion 7, a tip 8 of the lance 1 is formed. The channel 3 has a circular cross-section 9. In addition, the channel 3 has an axis 10. The main body 6 of the lance 1 has an axis 11. When inserting the lance 1 into the channel 3, the axis 11 of the main body 6 of the lance 1 is aligned with the axis 10 of the channel 3. Here, the axis 11 of the main body 6 of the lance 1 is preferably at least approximately on the axis 10 of the channel 3. The lance 1 is inserted in a feed direction in the channel 3. In this case, it is also possible for the lance 1 to be moved back and forth in sections when passing through the channel 3. That is, the lance 1 can also be partially moved against the feed direction 12 when driving through the channel 3.
Außerdem ist die Lanze 1 des Ausführungsbeispiels als Rotationslanze 1 ausgestaltet, so dass der Düsenabschnitt 7 um die Achse 11 drehbar ist. Die Drehung des Düsenabschnitts 7 kann dabei in einer Umfangsrichtung 13 oder entgegen der Umfangsrichtung 13 erfolgen. Außerdem ist es auch möglich, dass der Düsenabschnitt 7 wechselweise in und entgegen der Umfangsrichtung 13 verdreht oder rotiert wird. In diesem Ausführungsbeispiel ist der Düsenabschnitt 7 drehfest mit dem rohrförmigen Grundkörper 6 verbunden. Diese Verbindung ist stoffschlüssig ausgeführt. In diesem Ausfüh- rungsbeispiel ist hierfür eine umlaufende Schweißnaht 14 vorgesehen, die den Düsenabschnitt 7 mit dem rohrförmigen Grundkörper 6 verbindet. Hierdurch ist eine Verbindungsfläche 15 zwischen dem Düsenabschnitt 7 und dem rohrförmigen Grundkörper 6 abgedichtet, so dass ein Innenraum 16 bezüglich der Verbindungsfläche 15 nach außen abgedichtet ist. Der Innen- räum 16 der Lanze 1 bildet im Bereich des rohrförmigen Grundkörpers 6 ei- ne Leitung 17, über die ein unter hohem Druck stehendes Medium durch den rohrförmigen Grundkörper 6 zu dem Düsenabschnitt 7 führbar ist.In addition, the lance 1 of the embodiment is designed as a rotary lance 1, so that the nozzle portion 7 is rotatable about the axis 11. The rotation of the nozzle section 7 can take place in a circumferential direction 13 or counter to the circumferential direction 13. In addition, it is also possible that the nozzle portion 7 is alternately rotated in or against the circumferential direction 13 or rotated. In this embodiment, the nozzle portion 7 is rotatably connected to the tubular body 6. This connection is made cohesively. In this embodiment, an encircling weld seam 14 is provided for this purpose, which connects the nozzle section 7 with the tubular base body 6. In this way, a connecting surface 15 between the nozzle portion 7 and the tubular base body 6 is sealed, so that an inner space 16 is sealed with respect to the connecting surface 15 to the outside. The inner space 16 of the lance 1 forms in the region of the tubular base body 6 a ne line 17 through which a medium under high pressure through the tubular body 6 to the nozzle portion 7 is feasible.
An dem Düsenabschnitt 7 sind vorwärts gerichtete Düsen 18, 19 vorgese- hen. Ausgehend von dem Innenraum 16 der Lanze 1 sind die vorwärts gerichteten Düsen 18, 19 in der Vorschubrichtung 12 ausgerichtet. Entsprechend ist es auch möglich, dass die Lanze 1 an dem Düsenabschnitt 7 rückwärts gerichtete Düsen aufweist, die von dem Innenraum 16 aus entgegen der Vorschubrichtung 12 gerichtet sind. Über die Düsen 18, 19 ist das über die Leitung 17 zu dem Düsenabschnitt 7 geführte Medium strahlförmig abgebbar. In der Fig. 1 befindet sich die Spitze 8 der Lanze 1 in der Vorschubrichtung 12 betrachtet etwas vor einem Mündungsbereich 20, in dem die Querbohrung 4 in den Kanal 3 mündet. Über die vorwärts gerichteten Düsen 18, 19 wird das Medium strahlförmig abgestrahlt, was in der Fig. 1 durch Strahlen 21 , 22 veranschaulicht ist. Als Medium kann beispielsweise Wasser zum Einsatz kommen. Der Wasserstrahl 21 ist in der Vorschubrichtung 12 nach vorne gerichtet, so dass er in einem gewissen Abstand 23 im Inneren des Werkstücks 2 auftrifft. Bei der in der Fig. 1 dargestellten Stellung der Spitze 8 trifft der Wasserstrahl 21 im Mündungsbereich 20 auf den Grat 5 auf. Die Düse 18 ist hierbei so ausgestaltet, dass sich ein Strahldurchmesser 24 ergibt, der entlang des Strahls 21 im Wesentlichen konstant ist. Dadurch ergibt sich beim Auftreffen des Mediums auf den Grat 5 eine hohe mechanische Belastung, die zum Ablösen des Grates 5 führt. Hierbei werden besonders die Teile des Grates 5 abgelöst, die dem Strahl 21 eine große Angriffsfläche bieten.Forward nozzles 18, 19 are provided on the nozzle section 7. Starting from the interior 16 of the lance 1, the forward-looking nozzles 18, 19 are aligned in the feed direction 12. Accordingly, it is also possible that the lance 1 at the nozzle portion 7 has rearwardly directed nozzles, which are directed from the inner space 16 against the feed direction 12. Via the nozzles 18, 19, the guided via the line 17 to the nozzle section 7 medium jet-like delivered. In FIG. 1, the tip 8 of the lance 1 in the feed direction 12 is viewed slightly in front of a mouth region 20 in which the transverse bore 4 opens into the channel 3. About the forward nozzles 18, 19, the medium is radiated jet-shaped, which is illustrated in FIG. 1 by jets 21, 22. As a medium, for example, water can be used. The water jet 21 is directed forward in the feed direction 12 so that it impinges on the inside of the workpiece 2 at a certain distance 23. In the position of the tip 8 shown in FIG. 1, the water jet 21 impinges on the ridge 5 in the mouth region 20. In this case, the nozzle 18 is designed such that a beam diameter 24 results which is substantially constant along the beam 21. This results in the impact of the medium on the ridge 5, a high mechanical load, which leads to the detachment of the ridge 5. In this case, in particular the parts of the ridge 5 are replaced, which offer the beam 21 a large attack surface.
In diesem Ausführungsbeispiel sind die Düsen 18, 19 zumindest abschnittsweise durch Düsenbohrungen 25, 26 in dem Düsenabschnitt 7 gebildet. Ferner sind in dem Düsenabschnitt 7 konische Einlaufe 27, 28 für die vorwärts gerichteten Düsen 18, 19 ausgestaltet. Über die konischen Einlaufe 27, 28 gelangt das Medium aus dem Innenraum 16 der Lanze 1 in die Düsenboh- rungen 25, 26. Dadurch ist eine strömungsgünstige Zufuhr des Mediums zu den Düsen 18, 19 gewährleistet, so dass sich vorteilhafte Strahlformen der Strahlen 21 , 22 ergeben. Speziell kann ein gleich bleibender Strahldurch- messer 24 des Strahls 21 erzielt werden. Außerdem ist eine gleichmäßige Abgabe des Mediums ermöglicht, da Strömungsablösungen verhindert oder zumindest verringert sind. Dabei ergibt sich ein hoher Wirkungsgrad der vorwärts gerichteten Düsen 18, 19.In this exemplary embodiment, the nozzles 18, 19 are formed at least in sections by nozzle bores 25, 26 in the nozzle section 7. Further, in the nozzle portion 7 conical inlet 27, 28 designed for the forward nozzles 18, 19. About the conical inlet 27, 28, the medium from the interior 16 of the lance 1 enters the nozzle bore ments 25, 26. This ensures a streamlined supply of the medium to the nozzles 18, 19, so that advantageous jet shapes of the jets 21, 22 result. Specifically, a uniform beam diameter 24 of the beam 21 can be achieved. In addition, a uniform delivery of the medium is possible because flow separation is prevented or at least reduced. This results in a high efficiency of the forwardly directed nozzles 18, 19th
An dem Düsenabschnitt 7 der Lanze 1 sind außerdem tangential gerichtete Düsen 30, 31 vorgesehen. Über die tangential ausgerichteten Düsen 30, 31 ist das über die Leitung 17 zu dem Düsenabschnitt 7 führbare Medium strahlförmig abgebbar. Die Ausgestaltung der Lanze 1 , insbesondere der tangential gerichteten Düsen 30, 31 des Düsenabschnitts 7, ist im Folgenden auch unter Bezugnahme auf die Fig. 2 und 3 im weiteren Detail be- schrieben.At the nozzle portion 7 of the lance 1 also tangentially directed nozzles 30, 31 are provided. Via the tangentially oriented nozzles 30, 31, the medium which can be guided via the line 17 to the nozzle section 7 can be emitted in the form of a jet. The design of the lance 1, in particular of the tangentially directed nozzles 30, 31 of the nozzle section 7, is described below in further detail with reference to FIGS. 2 and 3.
Fig. 2 zeigt einen Schnitt durch den in Fig. 1 dargestellten Düsenabschnitt 7 der Lanze 1 entlang der mit dem Bezugszeichen Il bezeichneten Schnittlinie und durch das Werkstück 2, wobei sich die Spitze 8 der Lanze 1 im Bereich der Querbohrung 4 befindet. In diesem Ausführungsbeispiel sind die tangential gerichteten Düsen 30, 31 in dem Düsenabschnitt 7 ausgebildet, in dem auch die vorwärts gerichteten Düsen 18, 19 ausgebildet sind. Die tangential gerichteten Düsen können allerdings auch in einem weiteren Düsenabschnitt vorgesehen sein. An den Innenraum 16 der Lanze 1 schließt sich ein Stau- räum 34 an. Der Stauraum 34 ist durch eine Staufläche 35 (Fig. 1 ) begrenzt, die entgegen einer Strömungsrichtung des durch die Leitung 17 führbaren Mediums orientiert ist. Die Strömungsrichtung ist in diesem Ausführungsbeispiel gleich der Vorschubrichtung 12. Der Stauraum 34 ist durch eine Aussparung 36 in einer Wand 37 des Düsenabschnitts 7 gebildet. Dadurch er- streckt sich der Stauraum 34 in die Wand 37 des Düsenabschnitts 7. Die Düsenbohrungen 32, 33 münden einerseits in den Stauraum 34 und ande- rerseits an einer Außenfläche 38 des Düsenabschnitts 7. Die tangential gerichtete Düse 30 ist in der Umfangsrichtung 13 orientiert. Die tangential gerichtete Düse 31 ist entgegen der Umfangsrichtung 13 orientiert. Die beiden tangential gerichteten Düsen 30, 31 sind dabei entgegengesetzt zueinander ausgerichtet. Dadurch hebt sich ein im Betrieb erzeugter Drehimpuls zumindest näherungsweise auf. Allerdings wird beim Abgeben des Mediums über die tangential gerichteten Düsen 30, 31 eine Querkraft erzeugt. Diese Querkraft ist durch eine entgegen der seitlichen Ausrichtung der Düsen 30, 31 orientierte Ausrichtung der Düsenbohrungen 25, 26 zumindest teilweise kompensiert. Dadurch wird ein Verbiegen der Lanze 1 entlang ihrer Achse 11 verhindert.FIG. 2 shows a section through the nozzle section 7 of the lance 1 illustrated in FIG. 1 along the section line designated by the reference symbol II and through the workpiece 2, wherein the tip 8 of the lance 1 is located in the region of the transverse bore 4. In this embodiment, the tangentially directed nozzles 30, 31 are formed in the nozzle portion 7 in which also the forwardly directed nozzles 18, 19 are formed. However, the tangentially directed nozzles can also be provided in a further nozzle section. The interior 16 of the lance 1 is adjoined by a stowage space 34. The storage space 34 is bounded by a storage area 35 (FIG. 1) which is oriented counter to a flow direction of the medium which can be guided through the line 17. The flow direction is equal in this embodiment, the feed direction 12. The storage space 34 is formed by a recess 36 in a wall 37 of the nozzle portion 7. As a result, the storage space 34 extends into the wall 37 of the nozzle section 7. The nozzle bores 32, 33 lead on the one hand into the storage space 34 and on the other hand. On the other hand, on an outer surface 38 of the nozzle portion 7. The tangentially directed nozzle 30 is oriented in the circumferential direction 13. The tangentially directed nozzle 31 is oriented counter to the circumferential direction 13. The two tangentially directed nozzles 30, 31 are aligned opposite to each other. As a result, an angular momentum generated in operation is canceled out at least approximately. However, when dispensing the medium via the tangentially directed nozzles 30, 31, a transverse force is generated. This transverse force is at least partially compensated by an orientation of the nozzle bores 25, 26 oriented counter to the lateral alignment of the nozzles 30, 31. This prevents bending of the lance 1 along its axis 11.
Im Betrieb wird über die tangential gerichteten Düsen 30, 31 das Medium strahlenförmig abgegeben, wodurch Strahlen 39, 40 erzeugt sind. Bei der in der Fig. 2 dargestellten Drehstellung des Düsenabschnitts 7 der Lanze 1 trifft der Strahl 39 auf einen Teil 41 des Grates 5.In operation, the medium is radiated via the tangentially directed nozzles 30, 31, whereby beams 39, 40 are generated. In the illustrated in Fig. 2 rotational position of the nozzle portion 7 of the lance 1 of the beam 39 strikes a portion 41 of the ridge. 5
Wie in der Fig. 1 veranschaulicht, bietet der Teil 41 des Grats 5 dem unter einem flachen Winkel 42 auf den Grat 5 auftreffenden Strahl 21 nur eine geringe Angriffsfläche. Der Teil 41 des Grats 5 wird deshalb von dem Strahl 21 gegebenenfalls nicht abgetragen. Allerdings bietet der Teil 41 des Grates 5 dem Strahl 39 eine relativ große Angriffsfläche. Somit kann der Strahl 39 den Teil 41 des Grates 5 mit einer besseren Wirksamkeit abtragen als der Strahl 21.As illustrated in FIG. 1, the part 41 of the ridge 5 offers only a small attack surface to the jet 21 which strikes the ridge 5 at a shallow angle 42. The part 41 of the ridge 5 is therefore possibly not removed by the beam 21. However, the part 41 of the ridge 5 the beam 39 has a relatively large attack surface. Thus, the beam 39 can remove the part 41 of the ridge 5 with a better efficiency than the beam 21.
Eine erhöhte Wirksamkeit zum Abtragen des Grats 5, insbesondere des Teils 41 des Grats 5, kann durch einen Rotationsbetrieb erzielt werden. Solch ein Rotationsbetrieb ist im Folgenden auch unter Bezugnahme auf die Fig. 3 im weiteren Detail beschrieben. Fig. 3 zeigt die in Fig. 2 dargestellte Lanze des Ausführungsbeispiels mit dem Werkstück 2 entsprechend dem Ausführungsbeispiel in einer weiteren Drehstellung. Hierbei ist der Düsenabschnitt 7 gegenüber der in Fig. 2 dargestellten Drehstellung in der Umfangshchtung 13 so weit gedreht, dass die tangential gerichtete Düse 31 auf den Teil 41 des Grates 5 zielt. Der Strahl 40, der über die Düse 31 abgestrahlt wird, trifft dadurch auf den bereits von dem von der Düse 30 abgestrahlten Strahl 39 bearbeiteten Teil 41. Dadurch wird der Teil 41 des Grats 5 wechselseitig beaufschlagt. Beim Rotieren des Düsenabschnitts 7 in der Umfangsrichtung 13 dient die tangential gerichtete Düse 30 als vorauseilende Düse und die tangential gerichtete Düse 31 dient als nacheilende Düse 31. Allerdings ist auch ein Rotieren entgegen der Umfangsrichtung 13 möglich. Durch die wechselseitige Beaufschlagung des Grats 5 ergibt sich eine große mechanische Belastung auf den Grat 5, insbesondere den Teil 41 , so dass die Wirksamkeit der Lanze 1 weiter verbes- sert ist. Außerdem kann ein Durchmesser 45 (Fig. 1 ) des Düsenabschnitts 7 an den Querschnitt 9 angepasst sein. Hierbei ist der Durchmesser 45 vorzugsweise nicht kleiner als der 62. Teil des Abstandes der tangential gerichteten Düsen 30, 31 zu einer Kanalwand 46 gewählt.An increased efficiency for removing the ridge 5, in particular the part 41 of the ridge 5, can be achieved by a rotational operation. Such a rotation operation is also described below with reference to FIG. 3 in further detail. Fig. 3 shows the lance shown in Fig. 2 of the embodiment with the workpiece 2 according to the embodiment in a further rotational position. In this case, the nozzle section 7 is turned so far relative to the rotational position shown in FIG. 2 in the circumferential direction 13 that the tangentially directed nozzle 31 is aimed at the part 41 of the ridge 5. The jet 40 radiated via the nozzle 31 thereby strikes the part 41 already processed by the jet 39 radiated from the nozzle 30. As a result, the part 41 of the ridge 5 is mutually acted upon. When rotating the nozzle section 7 in the circumferential direction 13, the tangentially directed nozzle 30 serves as a leading nozzle and the tangentially directed nozzle 31 serves as a trailing nozzle 31. However, a rotation counter to the circumferential direction 13 is possible. The mutual application of the ridge 5 results in a large mechanical load on the ridge 5, in particular the part 41, so that the effectiveness of the lance 1 is further improved. In addition, a diameter 45 (FIG. 1) of the nozzle section 7 can be adapted to the cross section 9. In this case, the diameter 45 is preferably not smaller than the 62nd part of the distance of the tangentially directed nozzles 30, 31 to a channel wall 46.
Das zumindest näherungsweise tangential aus den tangential gerichteten Düsen 30, 31 austretende Medium wird bei einer entsprechenden Drehstellung des Düsenabschnitts 7 von der Kanalwand 46 in Richtung auf den Grat 5 abgelenkt. Hierdurch ergibt sich eine hohe mechanische Belastung des Grates 5. Durch die Staufläche 35 ergibt sich ein gewisser Staudruck, so dass das Medium mit großem Druck über die tangential gerichteten Düsen 30, 31 abgespritzt wird. Die Strahlen 21 , 22 treffen bedingt durch den flachen Winkel 42 mit hoher Wirksamkeit auf den rechtwinklig zur Achse 10 und somit Achse 11 stehenden Teil des Grats 5. Der Winkel 42 weist einen Wert von weniger als 30°, bevorzugt weniger als 20° auf. Ein gegebenenfalls verbleibender Teil 41 , der den Strahlen 21 , 22 eine relativ kleine Angriffsfläche bietet, kann durch die tangential gerichteten Strahlen 39, 40 abgetragen werden. Somit ergibt sich eine vorteilhafte Entgra- tungswirkung. Speziell können quer in den Kanal 3 gebohrte Querbohrungen 4 auch bei Werkstücken 2 vorgesehen werden, die aus gratbildenden Materialien hergestellt sind. Das zum Entgraten durch die Lanze 1 geführte Medium ist vorzugsweise ein Fluid, insbesondere Wasser. Allerdings können auch gasförmige Medien zum Einsatz kommen. Ferner ist es möglich, dass unterschiedliche Medien zum Einsatz kommen.The at least approximately tangentially from the tangentially directed nozzles 30, 31 exiting medium is deflected at a corresponding rotational position of the nozzle portion 7 of the channel wall 46 in the direction of the ridge 5. This results in a high mechanical load of the ridge 5. The storage surface 35 results in a certain back pressure, so that the medium is sprayed with high pressure on the tangentially directed nozzles 30, 31. The rays 21, 22 hit due to the flat angle 42 with high efficiency on the right angle to the axis 10 and thus axis 11 standing part of the ridge 5. The angle 42 has a value of less than 30 °, preferably less than 20 °. An optionally remaining part 41, which offers the beams 21, 22 a relatively small attack surface, can be removed by the tangentially directed beams 39, 40. This results in an advantageous deburring effect. Specifically, transverse bores 4 drilled transversely into the channel 3 can also be provided on workpieces 2 which are made of grout-forming materials. The medium guided for deburring through the lance 1 is preferably a fluid, in particular water. However, gaseous media can also be used. It is also possible that different media are used.

In einem weiteren, bevorzugt zeitgleichen Verfahrensschritt wird mittels zweier zweiter, näherungsweise quer zur Längsachse 11 orientierter Düsen 32, 33 dasselbe Medium in weiteren an- deren Richtungen gegen das Werkstück 2 gespritzt.

In a further method step, which is also preferably to be carried out simultaneously, the workpiece and the nozzle section are adjusted relative to each other in the direction of the longitudinal axis 11 and / or in the direction of the workpiece axis 10.

Letzteres erfolgt bevorzugt durch eine Rotation des Düsenabschnitts bzw. des Düsenkopfes. Alternativ wird das Werkstück mittels eines rotierenden Trägers relativ zur Lanze in Drehung versetzt. In a further method step, the workpiece and the nozzle section are moved relative to each other about the longitudinal axis 11 and / or around the work piece. piece-axis 10 twisted. The latter is preferably carried out by a rotation of the nozzle section or the nozzle head. Alternatively, the workpiece is rotated by means of a rotating carrier relative to the lance.
