- the powder tube extension comprises an extension tube 3, which is also referred to below as a powder tube.
- a connection sleeve 5 On the upstream end 3.5 of the extension tube 3 is a connection sleeve 5.
- the electrode holder 6 has on its upstream side on a powder channel 6.3, which forms the inlet of the powder tube extension.
- the coating powder or powder for short flows in the direction of the arrow P through the powder channel 6.3 and is divided by the wedge 7, so that it flows without appreciable turbulence on the web 6.2 of the electrode holder 6 into the powder tube 3.
- a tubular section 6.4 At the downstream end of the web 6.2.
- the electrode holder 6 serves to guide the high voltage from the contact point at the downstream end of the spray gun 30 to the resistors 11 in the tube 16.
- the tube 16 is also referred to below as a guide tube.
- the electrode holder 6 has an electrical conductive contact ring 14, which is in contact with the contact point of the spray gun 30 as soon as the powder tube extension is screwed onto the gun 30.
- Inside the electrode holder 6 there is an electrode channel 6.1 with a wire whose end is in contact with the contact ring 14. The other end of the wire is connected to the first of the series resistors 11.
- the connection 16.2 between the tubular portion 6.4 and the tube 16 may be formed for example as a press fit, screw or gluing.
- the tube 16 and the extension tube 3 are arranged concentrically with each other.
- a cap 9 At the downstream end of the tube 16 is a cap 9.
- the cap 9 is screwed to the tube 16. It has a thread 9.1 (see FIG. 8 ). But the cap 9 can also be pressed into the tube 16 or glued to it.
- the cap 9 has an opening from which a high voltage electrode 8 or shortly electrode protrudes. When the spray gun is in operation, the powder flowing past the high voltage electrode 8 will become electrostatically charged.
- the cap 9 is advantageously removable from the tube 16. If the electrode is worn, it is sufficient to replace only the cap 9 with the electrode 8.
- the tube 16 with the resistors 11 need not be replaced.
- the thus formed cap 9 carries at the upstream end a spring 15 which is electrically connected to the electrode 8.
- the spring 15 forms such a electrically resilient contact which presses on a contact plate 17 on the last resistor 11 in the tube 16.
- the tube 16 located inside the powder tube 3 with the series-connected resistors 11 and the cap 9 is held exactly concentric with the powder tube 3 by means of a wedge insert 2.
- the wedge insert 2 has for this purpose a sleeve-shaped section 2.7, which is inserted in the downstream end region of the powder tube 3.
- This sleeve-shaped section 2.7 is also referred to below as an outer sleeve-shaped section 2.7.
- the outer sleeve-shaped portion 2.7 has a taper on the outside at its upstream end. As a result, the wedge insert 2 can be more easily inserted into the powder tube 3.
- the wedge insert 2 has a further sleeve-shaped section 2.8, which is also referred to below as the inner sleeve-shaped section 2.8.
- the outer sleeve-shaped portion 2.7 and the inner sleeve-shaped portion 2.8 are arranged concentrically with each other and connected to each other via two radial webs 2.4.
- the two webs 2.4 each have a taper on the upstream side 2.2 and are thus wedge-shaped. Through the coating powder is passed by the two webs 2.4, without causing turbulence. The risk that the coating powder adheres or sinters on the webs 2.4 is thus significantly reduced.
- the wear of the wedge insert 2 is reduced by a suitable geometry of the tapers 2.2. Otherwise, the webs 2.4 would be removed in the course of time, in particular by abrasive coating powder.
- the two webs 2.4 advantageously also have tapers 2.1 on the downstream side on. They reduce the risk that the coating powder is swirled behind the webs 2.4.
- a Pulverstrahldüse 1 is provided, which is also referred to below as a jet nozzle or nozzle.
- the nozzle has a downstream portion 1.4 and an upstream portion 1.8.
- Paragraph 1.7 forms the boundary between the two sections 1.4 and 1.8.
- the paragraph 1.7 also forms a depth stop.
- the nozzle 1 is placed on the downstream end of the powder tube 3 and at the same time on the wedge insert 2.
- the nozzle 1 has reached its end position when the depth stop 1.7 of the nozzle 1 strikes the annular shoulder of the wedge insert 2.
- a latching connection ensures that the nozzle 1 does not slip off the powder tube 3 during the coating process.
- the nozzle 1 has for this purpose an O-ring 10, which can engage in a corresponding annular groove on the powder tube 3.
- the powder tube 3 and the wedge insert 2 are shaped so that they form a frictional engagement in the mounted state. So if you subtract the nozzle 1 from the powder tube 3, the frictional engagement ensures that the wedge insert 2 remains in the powder tube 3. If necessary, the operator can retrieve the wedge insert 2 by hand later from the powder tube 3. This makes the replacement of the nozzle 1 easier. It is necessary to remove only the nozzle to replace the nozzle 1. Another handle is not required.
- the jet nozzle 1 is designed as a flat jet nozzle.
- the nozzle opening 1.1 is slot-shaped.
- the electrostatically charged coating powder flows through the powder channel 1.3 of the flat jet nozzle and exits through the slot-shaped nozzle opening 1.1 as a flat powder jet from the nozzle 1.
- the two radial webs 2.4 of the wedge insert 2 and the slot-shaped nozzle opening 1.1 of the flat-jet nozzle 1 are preferably oriented the same.
- the nozzle slot 1.1 and the two radial webs 2.4 are thus aligned parallel to each other.
- the nozzle 1 has an axial groove 1.6 (FIG. FIG. 3 ) and the wedge insert 2 on its outside a nose 2.5.
- the nose 2.5 of the wedge insert 2 forms a positive connection with the groove 1.6 of the nozzle 1, so that when the nozzle 1 is rotated about its longitudinal axis LA, the wedge insert 2 is also rotated. In this way, the relative position of the wedge insert 2 with respect to the nozzle 1 is maintained, regardless of the orientation of the nozzle first
- the downstream end of the powder tube 3 is approximately 28 mm deep in the sleeve-shaped section 1.8 of the nozzle 1.
- the outer sleeve-shaped section 2.7 of the wedge insert also projects relatively far into the powder tube 3.
- the sleeve-shaped portion 2.7, the powder tube 3 and the sleeve-shaped portion 1.8 of the nozzle 1 form a labyrinth for the high voltage.
- the distance or air gap is extended.
- Another advantage over the in FIG. 1 As shown in the prior art is that the powder tube 3 now has fewer openings to the outside, it accounts for the three holes that receive the centering pins 300. Also, the distance or air gap is further increased outwards.
- the connecting sleeve 5 has on the inside an annular collar 5.2, on the one hand forms a stop for the tube 16 and on the other hand, a stop for the electrode holder 6.
- the inner wall of the collar 5.2 forms that part of the powder channel which connects the powder channel 6.3 of the electrode holder 6 with the powder channel 3.3 of the powder tube 3.
- the union nut 4 has inside a shoulder 5.3, which serves as a stop for the connection sleeve 5.
- the shoulder 5.3 presses on the connection sleeve 5 and fixes them.
- the powder channel 6.3 of the electrode holder 6 is pressed into the powder tube of the spray gun via the stop on the collar 5.3.

Abstract
Description
Die Erfindung betrifft einen Keileinsatz für eine Pulverrohrverlängerung einer mit Hochspannung betreibbaren Pulversprühpistole und eine Pulverrohrverlängerung mit Keileinsatz für eine mit Hochspannung betreibbare Pulversprühpistole.The invention relates to a wedge insert for a powder tube extension of a powder spray gun which can be operated with high voltage and a powder tube extension with wedge insert for a high-voltage powder spray gun.
Bei der elektrostatischen Pulverbeschichtung wird in einem ersten Arbeitsgang das zu beschichtende Werkstück mit einer Pulversprühpistole mit einer Schicht elektrostatisch aufgeladenem Pulver überzogen. In einem sich daran anschließenden Arbeitsgang wird das mit dem Pulver beschichtete Werkstück erwärmt bis das Pulver auf der Oberfläche des Werkstücks schmilzt und eine geschlossene Schicht bildet. Nach dem Abkühlen des Werkstücks ist diese Schicht eine geschlossene, fest auf dem Werkstück haftende Schutzschicht. Damit das Pulver elektrostatisch aufgeladen werden kann, befindet sich im Pulverkanal der Pulversprühpistole ein Elektrodenhalter mit einer unter Hochspannung stehenden Elektrode. Das Pulver strömt an der Elektrode vorbei und wird dabei elektrostatisch aufgeladen. Die an der Elektrode anliegende Hochspannung beträgt in der Regel zwischen 20 kV und 100 kV.In the electrostatic powder coating, the workpiece to be coated is coated with a powder spray gun with a layer of electrostatically charged powder in a first operation. In a subsequent operation, the powder coated workpiece is heated until the powder on the surface of the workpiece melts and forms a closed layer. After cooling the workpiece, this layer is a closed, firmly adhering to the workpiece protective layer. In order that the powder can be electrostatically charged, an electrode holder with a high-voltage electrode is located in the powder channel of the powder spray gun. The powder flows past the electrode and is thereby charged electrostatically. The voltage applied to the electrode high voltage is usually between 20 kV and 100 kV.
Werkstücke mit grösseren Abmessungen und grösseren Vertiefungen weisen häufig Bereiche auf, die der Beschichter mit einer konventionellen Pulversprühpistole nicht oder nur schwer erreichen kann. Damit aber auch solche Werkstücke mit hoher Qualität beschichtet werden können, wird eine konventionelle Pulversprühpistole mit einer Pulverrohrverlängerung ausgestattet. Dazu werden bei der Pulversprühpistole zuerst die Sprühdüse, der Elektrodenhalter und die Überwurfmutter, welche die Sprühdüse und den Elektrodenhalter auf der Pistole fixiert, abgenommen und dann die Pulverrohrverlängerung auf die Pistole geschraubt. Nun kann man die Pistole tiefer in das Werkstück hineinführen und man kommt besser an dies sonst unzugänglichen Bereiche des Werkstücks heran.Workpieces with larger dimensions and larger recesses often have areas that the coater can not or only with difficulty reach with a conventional powder spray gun. In order to be able to coat such workpieces with high quality, a conventional powder spray gun is equipped with a powder tube extension. For this purpose, the spray gun, the electrode holder and the union nut, which fixes the spray nozzle and the electrode holder on the gun are first removed at the powder spray gun and then screwed the powder tube extension on the gun. Now you can bring the gun deeper into the workpiece and it is better to approach this otherwise inaccessible areas of the workpiece.

Bei einer Ausführungsform des erfindungsgemässen Keileinsatzes ist eine Nase vorgesehen, die so ausgebildet ist, dass sie, wenn der Keileinsatz in einer Sprühdüse steckt, welche eine Nut aufweist, mit der Nut einen Formschluss bildet.In one embodiment of the wedge insert according to the invention, a nose is provided which is designed such that, when the wedge insert is inserted in a spray nozzle which has a groove, it forms a positive connection with the groove.
Bei einer weiteren Ausführungsform des erfindungsgemässen Keileinsatzes ist der Kanal hülsenförmig ausgebildet und konzentrisch zur Hülse angeordnet.In a further embodiment of the wedge insert according to the invention, the channel is sleeve-shaped and arranged concentrically to the sleeve.
Bei einer anderen Ausführungsform des erfindungsgemässen Keileinsatzes ist die Hülse derart ausgebildet, dass sie in ein Pulverrohr der Pulverrohrverlängerung hineinsteckbar ist und dabei mit dem Pulverrohr einen Reibschluss bildet.In another embodiment of the wedge insert according to the invention, the sleeve is designed such that it can be inserted into a powder tube of the powder tube extension and forms a frictional connection with the powder tube.
Bei einer Weiterbildung des erfindungsgemässen Keileinsatzes verjüngt sich die Hülse im stromaufwärtigen Endbereich.In a further development of the wedge insert according to the invention, the sleeve tapers in the upstream end region.
Bei einer Weiterbildung der Pulverrohrverlängerung ist eine Kappe vorgesehen, die mit dem Führungsrohr mittels einer lösbaren Verbindung verbunden ist. Wenn die Kappe beziehungsweise die Elektrodennadel in der Kappe verschlissen ist, kann die Kappe mit der Elektrodennadel einfach abgenommen und durch eine neue Kappe ersetzt werden. Hierfür bedarf es keines Servicepersonals.In a further development of the powder tube extension, a cap is provided which is connected to the guide tube by means of a detachable connection. If the cap or the electrode needle is worn in the cap, the cap with the electrode needle can be easily removed and replaced with a new cap. No service personnel are required for this.
Bei einer anderen Weiterbildung der Pulverrohrverlängerung ist in der Sprühdüse eine Nut vorgesehen, die so ausgebildet ist, dass sie mit der Nase des Keileinsatzes einen Formschluss bildet. Dadurch wird erreicht, dass die Sprühdüse immer die gleiche Orientierung wie der Keileinsatz hat. Dies wiederum stellt sicher, dass die Qualität des Pulversprühstrahls dauerhaft gleichbleibend hoch ist.In another development of the powder tube extension, a groove is provided in the spray nozzle, which is formed so that it forms a positive connection with the nose of the wedge insert. This ensures that the spray nozzle always has the same orientation as the wedge insert. This in turn ensures that the quality of the powder spray is consistently high.
Bei der Pulverrohrverlängerung kann zwischen der Sprühdüse und dem Pulverrohr eine Rastverbindung vorgesehen sein. Damit wird erreicht, dass die Sprühdüse auf dem Pulverrohr fixiert ist und bei Bedarf ohne Werkzeug abnehmbar ist.In the powder tube extension can be provided between the spray nozzle and the powder tube, a snap connection. This ensures that the spray nozzle on the Powder tube is fixed and can be removed without tools if necessary.
Die Rastverbindung kann bei der Pulverrohrverlängerung dadurch ermöglicht werden, dass die Sprühdüse einen O-Ring und das Pulverrohr eine Nut aufweisen. Dies ist eine einfache und kostengünstige Lösung.The latching connection can be made possible in the powder tube extension in that the spray nozzle has an O-ring and the powder tube has a groove. This is a simple and inexpensive solution.
Bei einer Ausführungsform der Pulverrohrverlängerung weist die Sprühdüse einen hülsenförmigen Abschnitt auf, der auf den Pulverkanal aufsteckbar ist. Dadurch wird der Weg zwischen dem Pulverkanal und dem Ende der Sprühdüse verlängert. Durch diese konstruktive Massnahme werden verschiedene nationale und internationale Normen erfüllt. Diese Normen schreiben vor, dass von der Pulversprühpistole keine Explosionsgefahr ausgehen darf. Es gilt zündfähige Teilentladungen (Entladungen in der ionisierten Luft) und/oder zündfähige Überschläge (Entladungen zu einem deutlich niederen Potential oder zur Masse) zu verhindern. Teilentladungen und Überschläge können entstehen, wenn eine von der Höhe der Hochspannung und der auftretenden Feldstärke abhängige Distanz unterschritten wird.In one embodiment of the powder tube extension, the spray nozzle has a sleeve-shaped section which can be plugged onto the powder channel. This prolongs the path between the powder channel and the end of the spray nozzle. This constructive measure fulfills various national and international standards. These standards require that the powder spray gun should not pose an explosion hazard. It is inflammable partial discharges (discharges in the ionized air) and / or ignitable flashovers (discharges to a significantly low potential or mass) to prevent. Partial discharges and flashovers may occur if the distance falls below a distance dependent on the magnitude of the high voltage and the occurring field strength.
Bei einer weiteren Ausführungsform der Pulverrohrverlängerung ist ein Prallteller vorgesehen, der auf das Führungsrohr aufsteckbar ist. Damit kann ein kegelförmiger Pulversprühstrahl erzeugt werden.In a further embodiment of the powder tube extension, a baffle plate is provided, which can be plugged onto the guide tube. Thus, a conical powder spray can be generated.
Zudem wird eine Flachstrahldüse für eine Pulverrohrverlängerung einer mit Hochspannung betreibbaren Pulversprühpistole vorgeschlagen bei der ein Düsenschlitz und ein rohrförmiger Abschnitt vorgesehen sind. Der rohrförmige Abschnitt ist derart ausgebildet, dass wenigstens der stromabwärtige Abschnitt eines radial angeordneten Keils eines Keileinsatzes formschlüssig darin platzierbar ist. In einem weiteren rohrförmigen Abschnitt der Flachstrahldüse ist eine Nut vorgesehen, die so ausgebildet ist, dass sie, wenn der Keileinsatz mit der Flachstrahldüse verbunden ist, mit der Nase des Keileinsatzes einen Formschluss bildet, sodass der Keil und der Düsenschlitz die gleiche Orientierung aufweisen. Zwischen dem rohrförmigen Abschnitt und dem weiteren rohrförmigen Abschnitt ist ein Absatz vorgesehen.In addition, a flat jet nozzle for a powder tube extension of a high-voltage operated powder spray gun is proposed in which a nozzle slot and a tubular portion are provided. The tubular Section is formed such that at least the downstream portion of a radially disposed wedge of a wedge insert is positively placed therein. In a further tubular portion of the flat jet nozzle, a groove is provided which is formed so that when the wedge insert is connected to the flat jet nozzle forms a positive connection with the nose of the wedge insert, so that the wedge and the nozzle slot have the same orientation. Between the tubular portion and the further tubular portion a shoulder is provided.
Schliesslich kann die oben beschriebene Pulverrohrverlängerung in einer manuell betreibbaren Pulversprühpistole, einer Automatiksprühpistole oder einer Pulverbecherpistole verwendet werden.Finally, the powder tube extension described above can be used in a manually operable powder spray gun, an automatic spray gun or a powder cup gun.

In
Die Pulverrohrverlängerung umfasst ein Verlängerungsrohr 3, welches im Folgenden auch als Pulverrohr bezeichnet wird. Auf dem stromaufwärtigen Ende 3.5 des Verlängerungsrohrs 3 steckt eine Anschlusshülse 5. In deren stromaufwärtigen Ende wiederum steckt ein Elektrodenhalter 6 mit einem Pulverkeil 7. Der Elektrodenhalter 6 weist auf seiner stromaufwärtigen Seite einen Pulverkanal 6.3 auf, der den Einlass der Pulverrohrverlängerung bildet. Das Beschichtungspulver oder kurz Pulver strömt in Richtung des Pfeils P durch den Pulverkanal 6.3 und wird durch den Keil 7 aufgeteilt, so dass es ohne nennenswerte Verwirbelung am Steg 6.2 des Elektrodenhalters 6 vorbei in das Pulverrohr 3 strömt. Am stromabwärtigen Ende des Stegs 6.2 befindet sich ein rohrförmiger Abschnitt 6.4. Der Elektrodenhalter 6 dient dazu die Hochspannung von der Kontaktstelle am stromabwärtigen Ende der Sprühpistole 30 zu den Widerständen 11 im Rohr 16 zu führen. Das Rohr 16 wird im Folgenden auch als Führungsrohr bezeichnet. Der Elektrodenhalter 6 weist dazu einen elektrisch leitfähigen Kontaktring 14 auf, der mit der Kontaktstelle der Sprühpistole 30 in Kontakt steht, sobald die Pulverrohrverlängerung auf die Pistole 30 geschraubt ist. Im Inneren des Elektrodenhalters 6 befindet sich ein Elektrodenkanal 6.1 mit einem Draht, dessen Ende mit dem Kontaktring 14 in Verbindung steht. Das andere Ende des Drahts ist mit dem ersten der in Reihe geschalteten Widerstände 11 verbunden. Auf den rohrförmigen Abschnitt 6.4 des Elektrodenhalters 6 ist das Rohr 16 gesteckt. Die Verbindung 16.2 zwischen dem rohrförmigen Abschnitt 6.4 und dem Rohr 16 kann beispielsweise als Presspassung, Schraubverbindung oder Klebung ausgebildet sein.The powder tube extension comprises an
Das Rohr 16 und das Verlängerungsrohr 3 sind zueinander konzentrisch angeordnet. Am stromabwärtigen Ende des Rohrs 16 befindet sich eine Kappe 9. Bei der in
Die Kappe 9 ist vorteilhafterweise vom Rohr 16 abnehmbar. Wenn die Elektrode verschlissen ist, genügt es, lediglich die Kappe 9 mit der Elektrode 8 auszuwechseln. Das Rohr 16 mit den Widerständen 11 braucht nicht ausgewechselt zu werden. Die so ausgebildete Kappe 9 trägt am stromaufwärtigen Ende eine Feder 15, die mit der Elektrode 8 elektrisch verbunden ist. Die Feder 15 bildet so einen elektrisch federnden Kontakt, der auf ein Kontaktplättchen 17 am letzten Widerstand 11 im Rohr 16 drückt.The
Das im Inneren des Pulverrohrs 3 befindliche Rohr 16 mit den in Reihe geschalteten Widerständen 11 und der Kappe 9 wird mittels eines Keileinsatzes 2 exakt konzentrisch zum Pulverrohr 3 gehalten. Der Keileinsatz 2 weist dazu einen hülsenförmigen Abschnitt 2.7 auf, der im stromabwärtigen Endbereich des Pulverrohrs 3 steckt. Dieser hülsenförmige Abschnitt 2.7 wird im Folgenden auch als äusserer hülsenförmiger Abschnitt 2.7 bezeichnet. Der äussere hülsenförmiger Abschnitt 2.7 weist aussen an seinem stromaufwärtigen Ende eine Verjüngung auf. Dadurch lässt sich der Keileinsatz 2 leichter in das Pulverrohr 3 stecken. Zudem weist der Keileinsatz 2 einen weiteren hülsenförmigen Abschnitt 2.8 auf, der im Folgenden auch als innerer hülsenförmiger Abschnitt 2.8 bezeichnet wird. In diesem steckt der Endbereich des Rohrs 16. Der äussere hülsenförmige Abschnitt 2.7 und der innere hülsenförmiger Abschnitt 2.8 sind konzentrisch zueinander angeordnet und über zwei radiale Stege 2.4 miteinander verbunden. Die beiden Stege 2.4 weisen auf der stromaufwärtigen Seite jeweils eine Verjüngung 2.2 auf und sind also keilförmig ausgebildet. Durch wird das Beschichtungspulver an den beiden Stegen 2.4 vorbeigeleitet, ohne dass Verwirbelungen entstehen. Die Gefahr, dass das Beschichtungspulver an den Stegen 2.4 anhaftet oder ansintert, wird so erheblich reduziert. Zudem wird durch eine geeignete Geometrie der Verjüngungen 2.2 der Verschleiss des Keileinsatzes 2 reduziert. Andernfalls würden insbesondere durch abrasives Beschichtungspulver die Stege 2.4 im Laufe der Zeit abgetragen. Die beiden Stege 2.4 weisen vorteilhafterweise auch auf der stromabwärtigen Seite Verjüngungen 2.1 auf. Sie reduzieren die Gefahr, dass das Beschichtungspulver hinter den Stegen 2.4 verwirbelt wird.The
Schliesslich ist eine Pulverstrahldüse 1 vorgesehen, die im Folgenden auch als Strahldüse oder Düse bezeichnet wird. Die Düse weist einen stromabwärtigen Abschnitt 1.4 und einen stromaufwärtigen Abschnitt 1.8 auf. Der Absatz 1.7 bildet die Grenze zwischen den beiden Abschnitten 1.4 und 1.8. Der Absatz 1.7 bildet zudem einen Tiefenanschlag. Die Düse 1 wird auf das stromabwärtige Ende des Pulverrohrs 3 und dabei gleichzeitig auch auf den Keileinsatz 2 gesteckt. Die Düse 1 ist auf ihrer Endposition angelangt, wenn der Tiefenanschlag 1.7 der Düse 1 auf die ringförmige Schulter des Keileinsatzes 2 trifft. Eine Rastverbindung sorgt dafür, dass die Düse 1 während des Beschichtungsvorgangs nicht vom Pulverrohr 3 rutscht. Die Düse 1 weist dazu einen O-Ring 10 auf, der in einer entsprechenden ringförmigen Nut auf dem Pulverrohr 3 einrasten kann.Finally, a
Das Pulverrohr 3 und der Keileinsatz 2 sind so geformt, dass sie im montierten Zustand einen Reibschluss bilden. Wenn man also die Düse 1 vom Pulverrohr 3 abzieht, sorgt der Reibschluss dafür, dass der Keileinsatz 2 im Pulverrohr 3 verbleibt. Bei Bedarf kann das Bedienpersonal den Keileinsatz 2 von Hand nachträglich aus dem Pulverrohr 3 herausziehen. Dadurch wird das Auswechseln der Düse 1 einfacher. Man muss nämlich zum Auswechseln der Düse 1 lediglich die Düse abziehen. Ein weiterer Handgriff ist nicht erforderlich.The
Bei der in
Die beiden radialen Stege 2.4 des Keileinsatzes 2 und die schlitzförmige Düsenöffnung 1.1 der Flachstrahldüse 1 sind vorzugsweise gleich orientiert. Der Düsenschlitz 1.1 und die beiden radialen Stege 2.4 sind also zueinander parallel ausgerichtet. Um dies zu erreichen, weist die Düse 1 im Inneren eine axiale Nut 1.6 (
Das stromabwärtige Ende des Pulverrohrs 3 steckt ca. 28 mm tief im hülsenförmigen Abschnitt 1.8 der Düse 1. Der äussere hülsenförmige Abschnitt 2.7 des Keileinsatzes ragt ebenfalls relativ weit in den Pulverrohr 3 hinein. Auf diese Weise bilden der hülsenförmige Abschnitt 2.7, das Pulverrohr 3 und der hülsenförmige Abschnitt 1.8 der Düse 1 ein Labyrinth für die Hochspannung. Die Distanz beziehungsweise Luftstrecke wird verlängert. Ein weiterer Vorteil gegenüber dem in
Die Anschlusshülse 5 weist innen einen ringförmigen Kragen 5.2 auf, der einerseits einen Anschlag für das Rohr 16 und andererseits einen Anschlag für den Elektrodenhalter 6 bildet. Die Innenwand des Kragens 5.2 bildet jenen Teil des Pulverkanals, der den Pulverkanal 6.3 des Elektrodenhalters 6 mit dem Pulverkanal 3.3 des Pulverrohrs 3 verbindet.The connecting
Die Überwurfmutter 4 weist innen eine Schulter 5.3 auf, die als Anschlag für die Anschlusshülse 5 dient. Wenn die Überwurfmutter 5 auf die Pistole geschraubt wird, drückt die Schulter 5.3 auf die Anschlusshülse 5 und fixiert sie. Zudem wird dabei über den Anschlag am Kragen 5.3 auch der Pulverkanal 6.3 des Elektrodenhalters 6 in das Pulverrohr der Sprühpistole gedrückt.The
Der O-Ring 12 auf dem Pulverrohr 3 bildet einen elastischen Widerstand für die Überwurfmutter 4. Die Überwurfmutter 4 kann bei Bedarf mit geringem Kraftaufwand mit dem O-Ring 12 zusammen über die Nut am Rohr hinweg geschoben werden. Der O-Ring 12 hält die Überwurfmutter 4 in der jeweiligen Position.The O-

Es sind Pulverrohrverlängerungen mit verschiedenen Längen herstellbar. Die Pistole kann mit den verschiedenen Pulverrohrverlängerungen beispielsweise zwischen 150 mm und 500 mm verlängert werden.There are powder tube extensions with different lengths to produce. The gun can be extended with the various powder tube extensions, for example, between 150 mm and 500 mm.
Wenn das Bedienpersonal die Pulverrohrverlängerung beispielsweise zu Reinigungszwecken zerlegen möchte, zieht die Person die Flachstrahldüse 1 von Hand vom Pulverrohr 3 ab. Der Keileinsatz 2 verbleibt dabei im Pulverrohr 3 wie in

Die vorhergehende Beschreibung der Ausführungsbeispiele gemäss der vorliegenden Erfindung dient nur zu illustrativen Zwecken und nicht zum Zwecke der Beschränkung der Erfindung. Im Rahmen der Erfindung sind verschiedene Änderungen und Modifikationen möglich, ohne den Umfang der Erfindung sowie ihre Äquivalente zu verlassen. So sind beispielsweise die verschiedenen in den
Die Pulverrohrverlängerung kann verschieden lang ausgebildet sein. Welche Länge die Pulverrohrverlängerung haben soll, kann sich beispielsweise aus den zu beschichtenden Werkstücken ergeben.The powder tube extension can be designed to have different lengths. The length of the powder tube extension should, for example, result from the workpieces to be coated.
Die Pulverrohrverlängerung kann auch auf eine Automatikpistole montiert werden. Unter einer Automatikpistole wird eine Sprühpistole verstanden, die nicht von Hand gehalten wird, sondern beispielsweise an einem Roboter oder einer Linearführung befestigt oder fix installiert ist.The powder tube extension can also be mounted on an automatic gun. Under an automatic gun is understood to be a spray gun that is not held by hand, but for example, attached to a robot or a linear guide or fixed installed.
Schliesslich kann die Pulverrohrverlängerung auch auf eine Pulverbecherpistole aufgeschraubt werden. Die Pulverbecherpistole weist einen Pulverbecher inklusive Pulverinjektor auf, die direkt, zum Beispiel oberhalb an der Sprühpistole angebracht sind.Finally, the powder tube extension can also be screwed onto a powder cup gun. The powder cup gun has a powder cup including powder injector, which are attached directly, for example, above the spray gun.
