The nozzle lance implements a circular movement (22) around a longitudinal center axis (12) of the opening. A running movement (21) of the nozzle lance in the inlet opening is smaller than the speed of the rotation movements and the circular movement. An assigned outlet opening (15) remains open during processing of cooling channels (13. 1, 13.2) that branch out from the inlet opening in different directions.

Description

Die Erfindung betrifft ein Verfahren zum Entgraten, Entspanen und/oder Reinigen der Kühlkanäle in einem Zylinderkopf, die von einer Eingangsöffnung ausgehen, sich in verschiedene Richtungen verzweigen und durch den Zylinderkopf geführt in einer gemeinsamen Ausgangsöffnung enden, wobei in die Eingangsöffnung eine Düsenlanze mit mehreren, in verschiedene Richtungen abgegebenen Düsenstrahlen eingeführt und in Drehbewegungen versetzt wird und wobei während der Bearbeitung der von der Eingangsöffnung verzweigenden Kühlkanäle die zugeordnete Ausgangsöffnung offen gehalten wird.The invention relates to a method for deburring, removing and / or cleaning the cooling channels in a cylinder head, which start from an inlet opening, branch in different directions and led through the cylinder head in a common outlet opening, wherein in the inlet opening a nozzle lance with several, introduced in different directions jets and is set in rotational movements and wherein during the processing of the branching of the input port cooling channels, the associated output port is kept open.

Aus der DE 196 21 869.1 A1 ist eine Vorrichtung zum Bearbeitung der Innenwandung eines Hubkolbenzylinders bekannt, bei dem eine Düsenlanze mit zwei in unterschiedlichen Winkeln am Lanzenkopf abgehenden Düsenstrahlen bearbeitet wird. Dabei wird die Düsenlanze auf der Mittellängsachse des Zylinderraumes auf- und abbewegt und führt dabei eine Rotationsbewegung um ihre Längsachse aus. Die Verwendung der in unterschiedlichen Winkeln im Lanzenkopf eingebauten Düsen mit den abgegebenen Düsenstrahlen hat dabei den Sinn, dass die Düsenstrahlen bei der Umdrehung der Düsenlanze in unterschiedlichen Winkeln auf die Innenwandung des Zylinderraumes auftreffen und dabei die Entgratungs-, Enspanungs- und/oder Reinigungsarbeit verbessern.From the DE 196 21 869.1 A1 a device for processing the inner wall of a reciprocating cylinder is known in which a nozzle lance is processed with two outgoing at different angles on the lance head jet. In this case, the nozzle lance is moved up and down on the central longitudinal axis of the cylinder chamber and thereby performs a rotational movement about its longitudinal axis. The use of the built-in at different angles in the lance head nozzles with the output nozzle jets has the sense that the jets in the Rotation of the nozzle lance impinge on the inner wall of the cylinder chamber at different angles and thereby improve the Entgratungs-, Enspanungs- and / or cleaning work.

Aus der DE 20 2007 007 903 U1 ist eine Vorrichtung zum Entgraten, Entspanen und/oder Reinigung der Wasser- oder Ölkammern eines Zylinderkopfes bekannt. Die geschlossene Kammer hat in Längsrichtung, die mit der Einfahrbewegung der Düsenlanze zusammenfällt, Hinterschnitte. Damit diese Hinterschnitte entgratet, entspant oder gereinigt werden, wird eine besonders ausgebildete Düsenlanze verwendet. Die Düsenlanze ist als Flachdüse ausgebildet, deren Breitstrahl sich über einen Winkelbereich erstreckt, der zu gleichen Teilen oder mit seinen Endkanten unsymmetrisch zur Düsenlängsachse steht. Dabei bearbeitet der Düsenstrahl beim Herausfahren die Hinterschnitte der Kammer.From the DE 20 2007 007 903 U1 a device for deburring, cleaning and / or cleaning the water or oil chambers of a cylinder head is known. The closed chamber has undercuts in the longitudinal direction, which coincides with the retraction movement of the nozzle lance. To ensure that these undercuts are deburred, expanded or cleaned, a specially designed nozzle lance is used. The nozzle lance is designed as a flat nozzle whose broad jet extends over an angular range which is in equal parts or with its end edges asymmetrical to the nozzle longitudinal axis. The nozzle jet processes the undercuts of the chamber during retraction.

Die GB 2 293 558 A , die US 6 804 579 B1 , die DE 4 303 188 C1 , die DE 20 2007 007 903 U1 , die EP 0 384 873 A und die US 5 502 881 A zeigen Verfahren und Vorrichtungen zum Entgraten auch von Kühlkanälen in Zylinderköpfen die mit Düsenlanzen arbeiten, welche eine Einfahrbewegung und eine Drehbewegung ausführen. Diese Bewegung der Düsenlanze reicht aus, wenn es sich um einfache, durch den Zylinderblock geführte Kühlkanäle handelt.The GB 2 293 558 A , the US Pat. No. 6,804,579 B1 , the DE 4 303 188 C1 , the DE 20 2007 007 903 U1 , the EP 0 384 873 A and the US 5 502 881 A show methods and apparatuses for deburring and cooling ducts in cylinder heads which work with nozzle lances, which perform a retraction movement and a rotational movement. This movement of the nozzle lance is sufficient if it is simple, guided through the cylinder block cooling channels.

Derartige Verfahren und Vorrichtungen sind nicht zur Bearbeitung der Kühlkanäle in einem Zylinderkopf einsetzbar, da die Kühlkanäle wohl von einer Einfangsöffnung ausgehen, sich dann in verschiedene Richtungen verzweigen und durch den Zylinderkopf geführt in einer gemeinsamen Ausgangsöffnung der Zylinderblock wieder verlassen. Diese Führung der Kühlkanäle bringt eine verbesserte Kühlleistung, erschwert jedoch die Bearbeitung dieser Kühlkanäle.Such methods and devices are not used for processing the cooling channels in a cylinder head, since the cooling channels probably start from a capture opening, then branch in different directions and leave through the cylinder head in a common outlet opening of the cylinder block again. This leadership of the cooling channels brings improved cooling performance, but complicates the processing of these cooling channels.

Es ist Aufgabe der Erfindung ein Verfahren der eingangs erwähnten Art so auszubilden, dass mit einer Düsenlanze derartig verzweigte Kühlkanäle besser entgratet, entspant und/oder gereinigt werden können.It is an object of the invention to provide a method of the type described above in such a way that with a nozzle lance such branched cooling channels can be better deburred, expanded and / or cleaned.

Die gestellte Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.The stated object is achieved with the features of claim 1.

Durch die zusätzliche Zirkularbewegung und die Abstimmung der Einfahrbewegung und der Zirkularbewegung wird eine Art Schraubbewegung der Düsenstrahlen in den Anfangsabschnitten der Kühlkanäle erzeugt, wobei die Düsenstrahlen überlappend in die Anfangsabschnitte der Kühlkanäle einbringen und dadurch die Wirkung wesentlich verstärken. Eine bevorzugte Ausbildung des Verfahrens sieht dabei vor, dass die Drehzahl der Zirkularbewegung ungefähr 600 U/min und die Vorschubgeschwindigkeit der Einfahrbewegung der Düsenlanze etwa 100 mm/min gewählt wird. Dann dringen die Düsenstrahlen überlappend in die Eingangsabschnitte der Kühlkanäle ein und verbessern so die Wirkung auf den Wandungen der Kühlkanäle, was zu einer Verbesserung der Bearbeitung führt.By the additional circular motion and the tuning of the retraction movement and the circular movement, a kind of screwing movement of the jet streams is generated in the initial sections of the cooling channels, wherein the jet streams overlap into the initial sections of the cooling channels and thereby substantially enhance the effect. A preferred embodiment of the method provides that the rotational speed of the circular motion is selected to be approximately 600 rpm and the feed rate of the retraction movement of the nozzle lance approximately 100 mm / min. Then, the nozzle jets overlap with each other into the entrance portions of the cooling passages, thus improving the effect on the walls of the cooling passages, resulting in an improvement in workability.

Da ein Zylinderblock viele Eingangsöffnungen zu verzweigten Kühlkanälen aufweist, die jeweils in einer zugeordneten Ausgangsöffnung enden, sieht eine Weiterbildung des Verfahrens vor, dass bei einem Zylinderkopf mit mehreren, von oben nach unten angeordneten Eingangsöffnungen mit zugeordneten Ausgangsöffnungen die Düsenlanze nacheinander in die Eingangsöffnungen eingeführt und in Zirkularbewegung versetzt wird. danach die Düsenlanze nacheinander in die zugeordneten Ausgangsöffnungen mit gleicher Vorschubgeschwindigkeit der Einfahrbewegung und gleicher Zirkularbewegung eingeführt wird.Since a cylinder block has many inlet openings to branched cooling channels, each ending in an associated outlet opening, a development of the method provides that in a cylinder head with several, arranged from top to bottom inlet openings with associated outlet openings, the nozzle lance sequentially inserted into the inlet openings and in Circular motion is offset. Thereafter, the nozzle lance is successively introduced into the associated output openings at the same feed rate of the retraction movement and the same circular motion.

Damit bei der Bearbeitung des Zylinderkopfes die Umwelt nicht verschmutzt wird, sieht eine Weiterbildung der Vorrichtung vor, dass während der Bearbeitung der Kühlkanäle über die Eingangsöffnungen und über die Ausgangsöffnungen unterhalb des Zylinderkopfes eine Auffangwanne angeordnet wird, mit der die aus den Kühlkanälen ausgespülten Entgratungs-, Entspanungs- und/oder Reinigungsteile in dem Hochdruck-Bearbeitungsmedium aufgenommen werden.So that the environment is not polluted during the machining of the cylinder head, a development of the device provides that during the processing of the cooling channels via the inlet openings and the outlet openings below the cylinder head a collecting trough is arranged, with which the flushed out of the cooling channels Entgratungs-, Discharge and / or cleaning parts are included in the high-pressure processing medium.

Das Verfahren kann so weitergebildet sein, dass eine einzige Düsenlanze für die Bearbeitung der Eingangs- und Ausgangsöffnungen vorgesehen wird und dass beim Wechsel der Bearbeitung der Zylinderkopf um 180° gedreht wird.The method may be developed so that a single nozzle lance for the processing of the input and output ports is provided and that when changing the machining of the cylinder head is rotated by 180 °.

Die Erfindung wird anhand von in den Zeichnungen dargestellten Ausführungsbeispielen näher erläutert. Es zeigen:

In Fig. 1 ist ein Teilschnitt durch einen Zylinderkopf 10 gezeigt, wobei der Teilschnitt durch eine Eingangsöffnung11 geht, von der zwei Anfangsabschnitte 14.1 und 14.2 von zwei Kühlkanälen 13.1 und 13.2 abzweigen. Dabei brauchen die beiden Kühlkanäle 13.1 und 13.2 nicht unbedingt auf einer senkrechten Ebene durch den Zylinderkopf 10 liegen, sie können auch gegenüber einer senkrechten Ebene um verschiedene Winkel versetzt sein. Die beiden Kühlkanäle 13.1 und 13.2 enden in einer gemeinsamen Ausgangsöffnung 15 auf der anderen Seite des Zylinderkopfes 10. So ist jeder Eingangsöffnung 11 eine Ausgangsöffnung 15 zugeordnet.In Fig. 1 a partial section through a cylinder head 10 is shown, wherein the partial section passes through an inlet opening 11, of which two initial sections 14.1 and 14.2 branch off from two cooling channels 13.1 and 13.2. The two cooling channels 13.1 and 13.2 need not necessarily lie on a vertical plane through the cylinder head 10, they can also be offset from a vertical plane by different angles. The two cooling channels 13.1 and 13.2 terminate in a common outlet opening 15 on the other side of the cylinder head 10. Thus, each inlet opening 11 is assigned an outlet opening 15.

Zum Entgraten, Entspanen und/oder Reinigen der Kühlkanäle 13.1 und 13.2 wird eine Düsenlanze 20 verwendet, in die mehrere Düsen im Lanzenkopf so eingebaut sind, sodass sie mehrere Düsenstrahlen 25 in verschiedenen Richtungen nach vorne abgeben kann. Die Düsenlanze 20 wird im Abstand parallel zur Längsmittelachse 12 der Eingangsöffnung 11 mit einer Einfahrbewegung 21 eingeführt und führt dabei nicht nur ihre Drehbewegung um die Längsachse sondern eine zusätzliche Zirkularbewegung 22 um die Längsmittelachse 12 der Eingangsöffnung 11 aus. Die Einfahrbewegung 21 erfolgt vorzugsweise mit einer Vorschubgeschwindigkeit von etwa 100 mm/min. und die Zirkularbewegung 22 erfolgt ungefähr mit 600 U/min. Damit wird erreicht, dass bei der Einfahrbewegung 21 der Düsenlanze 20 die Eingangsabschnitte 14.1 und 14.2 der Kühlkanäle 13.1 und 13.2 bei jeder Umdrehung der Düsenlanze 20 um die Längsmittelachse 12 der Eingangsöffnung 11 treffen, jedes Mal mehr in diese Anfangsabschnitte 14.1 und 14.2 eindringen und dabei von Umdrehung zu Umdrehung sich überlappen. Die dadurch nach Art einer Schraubbewegung auf den Wandungen der Anfangsabschnitte 14.1 und 14.2 auftreffenden Düsenstrahlen 25 bringen eine ausgezeichnete Wirkung, so dass die Kühlkanäle 13.1 und 13.2 eindeutig entgratet, entspant und/oder gereinigt werden. Da die Ausgangsöffnung 15 dabei offen bleibt, kann das ausgespülte Gut den Zylinderkopf 10 verlassen.For deburring, removing and / or cleaning the cooling channels 13.1 and 13.2, a nozzle lance 20 is used, in which a plurality of nozzles in the lance head are installed so that they can deliver several jets 25 in different directions forward. The nozzle lance 20 is inserted at a distance parallel to the longitudinal central axis 12 of the input opening 11 with a retraction movement 21 and thereby not only performs its rotational movement about the longitudinal axis but an additional circular motion 22 about the longitudinal central axis 12 of the inlet opening 11. The retraction movement 21 is preferably carried out at a feed rate of about 100 mm / min. and the circular motion 22 is approximately 600 rpm. This ensures that when entering the 21 of the nozzle lance 20, the input sections 14.1 and 14.2 of the cooling channels 13.1 and 13.2 meet at each revolution of the nozzle lance 20 about the longitudinal central axis 12 of the inlet opening 11, each time more in these initial sections 14.1 and 14.2 penetrate and thereby Turn to turn overlap. The thus occurring in the manner of a screwing on the walls of the initial sections 14.1 and 14.2 nozzle jets 25 bring an excellent effect, so that the cooling channels 13.1 and 13.2 clearly deburred, entspant and / or cleaned. Since the output port 15 remains open, the flushed Good leave the cylinder head 10.

Der in Fig. 1 gezeigte Teil 16 steht außerhalb der Kühlkanäle 13.1 und 13.2 mit dem Zylinderkopf 10 in Verbindung.The in Fig. 1 shown part 16 is outside the cooling channels 13.1 and 13.2 with the cylinder head 10 in conjunction.

In Fig. 2 ist in schematischer Weise ein Verfahren gezeigt, das mit einer Düsenlanze 20 mit Düsenstrahlen 25, die von oben nach unten aneinander gereihten Eingangsöffnungen 11.1 bis 11.n nacheinander mit den nach Fig. 1 erfolgenden Bewegungen bearbeitet. Dabei wird die Düsenlanze 20 in der Abwärtsbewegung 30 nacheinander auf die Eingangsöffnungen 11.1 bis 11.n gebracht, wobei stets die Zirkularbewegung 22 um die Längsmittelachsen 12 der Eingangsöffnungen 11.1 bis 11.n ausgeführt wird und die Düsenlanze 20 in die Eingangsöffnungen 11.1 bis 11.n mit der vorgewählten Vorschubgeschwindigkeit der Einfahrbewegung 21 eingeführt wird.In Fig. 2 is schematically shown a method that with a nozzle lance 20 with nozzle jets 25, the top-down juxtaposed input openings 11.1 to 11.n successively with the after Fig. 1 processed movements. In this case, the nozzle lance 20 is brought in the downward movement 30 successively to the inlet openings 11.1 to 11.n, wherein the circular movement 22 is always performed around the longitudinal center axes 12 of the inlet openings 11.1 to 11.n and the nozzle lance 20 in the inlet openings 11.1 to 11.n is introduced at the preselected feed rate of the retraction 21.

Danach kann die Düsenlanze 20' auf die Seite der Ausgangsöffnungen 15.1 bis 15.n des Zylinderkopfes 10 gebracht werden und das Spiel wiederholt sich von Ausgangsöffnung 15.1 bis zur Ausgangsöffnung 15.n. Die Abwärtsbewegung 30' der Düsenlanze 20 ist auf die Ausgangsöffnungen 15.1 bis 15.n so eingestellt, dass die Düsenlanze 20 eine zusätzliche Zirkularbewegung um die Längsmittelachse der betreffenden Ausgangsöffnung 15.1 bis 15.2 ausführt. Die Einfahrbewegung erfolgt wieder mit vorgewählter Vorschubgeschwindigkeit und die Düsenlanze 20' führt wieder eine Drehbewegung um die eigene Längsachse aus.Thereafter, the nozzle lance 20 'can be brought to the side of the output ports 15.1 to 15.n of the cylinder head 10 and the game repeats from the output port 15.1 to the output port 15.n. The downward movement 30 'of the nozzle lance 20 is adjusted to the outlet openings 15.1 to 15.n so that the nozzle lance 20 carries out an additional circular movement about the longitudinal central axis of the relevant outlet opening 15.1 to 15.2. The retraction movement takes place again at a preselected feed rate and the nozzle lance 20 'again performs a rotational movement about its own longitudinal axis.

An die Stelle von zwei verstellbaren Düsenlanzen 20 und 20' kann auch der Zylinderkopf 10 um 180° gedreht werden, so dass die einzige Düsenlanze 20 die Bewegungen für die Eingangs- und Ausgangsöffnungen ausführen kann. Die Hochdruck-Flüssigkeit mit den ausgespülten Teilen wird aus den offenen Ausgangs- bzw. Eingangsöffnungen von einer unter dem Zylinderkopf 10 angeordneten Auffangwanne 40 aufgefangen, um eine Verschmutzung der Umwelt zu vermeiden.In place of two adjustable nozzle lances 20 and 20 'and the cylinder head 10 can be rotated by 180 °, so that the single nozzle lance 20 can perform the movements for the input and output ports. The high-pressure liquid with the flushed parts is collected from the open exit or inlet openings of a arranged below the cylinder head 10 drip tray 40 to avoid pollution of the environment.

Method according to claim 1, characterised in that on a cylinder head (10) with several inlet openings (11.1 to 11.n) arranged from top to bottom with allocated output openings (15.1 to 15.n), the nozzle lance (20) is inserted successively (30) in the inlet openings (11.1 to 11.n) and put into circular motions (22) and that then the nozzle lance (20) is inserted successively (30') in the allocated outlet openings (15.1 to 15.n) with the same advance speed of the insertion motion (21) and the same circular motion (22).
  3. Method according to claim 2,
    characterised in that
    during processing of the coolant canals (13.1 and 13.2) via the inlet openings (11.1 and 11.n) and via the outlet openings (15.1 and 15.n), below the cylinder head (10) is arranged a catchment tray, with which the particles removed by deburring, uncramping and/ cleaning and flushed out of the coolant canals (13.1 and 13.2) are captured in the high pressure processing medium.
  4. Method according to claim 2,
    characterised in that
    a single nozzle lance (20) is provided for processing the inlet and outlet openings (11.1 to 11.n and 15.1 to 15.n) and that on change of processing, the cylinder head (10) is rotated through 180°.
