Description

Die vorliegende Erfindung betrifft eine Blendeneinheit für einen Brenner, mit einer Blende und einem Träger für die Blende, welcher zwei die Blende tragende Seitenteile aufweist, die durch Befestigungsmittel, welche der Befestigung der Blendeneinheit im Brenner dienen, miteinander verbunden sind.The present invention relates to an aperture unit for a burner, with an aperture and a support for the Cover, which has two side parts supporting the cover, by fasteners which are used to fasten the Aperture unit are used in the burner, are interconnected.

In der CH-A-654900 wird eine Blendeneinheit gezeigt, welche eine als kreisförmige Platte ausgebildete Blende mit einer zentralen Oeffnung für den Luftdurchtritt aufweist. Die Blende mit Halter ist mit Stützbeinen versehen, welche die Blende mit einer Buchse verbinden, die dazu dient, die Blendeneinheit mit einer Schraube auf der Düsenstange zu befestigen. Diese Blendeneinheit ist nicht sehr stabil. Die Stützbeine sind nur mit dem vorderen Teil der Buchse verbunden, so dass bereits relativ kleine Kräfte ausreichen, um diese Stützbeine zu verbiegen. Dadurch kommt die Blende inbezug auf die Düse exzentrisch zu liegen, was zu Funktionsstörungen des Brenners führt. Als Nachteil erweist sich auch die Notwendigkeit, die Zündelektroden an der Blende zu befestigen, denn dadurch wird das Auswechseln der Zündelektroden erschwert. Die bekannte Blendeneinheit ist relativ teuer in der Herstellung, weil die Buchse ein teures Drehteil ist und durch eine aufwendige Nietoperation mit den Stützbeinen verbunden werden muss.In CH-A-654900 an aperture unit is shown which an aperture designed as a circular plate with a central opening for the passage of air. The aperture with holder is provided with support legs, which the panel with Connect a socket that is used to connect the panel unit with a screw on the nozzle rod. This Aperture unit is not very stable. The support legs are just connected to the front part of the socket, so that already relatively small forces are sufficient to support these legs bend. As a result, the orifice comes into relation to the nozzle to be eccentric, causing the burner to malfunction leads. A disadvantage also turns out to be the need To attach ignition electrodes to the panel, because this will it is difficult to replace the ignition electrodes. The well-known Aperture unit is relatively expensive to manufacture because of the Bushing is an expensive turned part and due to an elaborate Rivet surgery must be connected to the support legs.

Bei einem im Handel erhältlichen Brenner wird eine Blendeneinheit verwendet, bei der die Stützbeine Teile eines Trägers sind, welcher aus zwei Seitenteilen besteht, welche durch zwei in Abstand voneinander angeordnete Ringe miteinander verbunden sind. Die Verbindungsstellen der Seitenteile mit der Blende und den Ringen sind geschweisst. An einem der beiden Steitenteile ist ein Befestigungsblech angeschweisst, welches der Befestigung der Zündelektroden dient. Bei der Montage des Brenners wird die Blendeneinheit auf die Düsenstange gesteckt und durch eine Schraube an dieser festgeklemmt. Diese Blendeneinheit besteht aus relativ billigen Stanzteilen. Nachteilig ist jedoch der relativ grosse Herstellungsaufwand. Wie bereits erwähnt, werden die Ringe, die Seitenteile, das Befestigungsblech für die Zündelektroden und die Blende durch eine Vielzahl von Schweissstellen miteinander verbunden. Dies erfordert zunächst, dass die Teile vorgängig von Oel und Fettrückständen befreit werden, damit einwandfreie Schweissstelle entstehen können. In der Praxis hat sich aber gezeigt, dass trotz Vorreinigung der Teile die Schweissstellen des öfteren fehlerhaft sind und einer Beanspruchung nicht standhalten. Des weiteren ist nachteilig, dass die Teile vorgängig der Schweissoperation genau ausgerichtet werden müssen. Wegen der Vielzahl von Schweissstellen ist auch die abschliessende Kontrolle der fertiggestellten Einheit sehr aufwendig. Diese einzelnen Arbeitsschritte summieren sich zu einem beträchtlichen Arbeitsaufwand, den zu reduzieren von besonderer Bedeutung ist, weil die Blendeneinheit in relativ grossen Stückzahlen zur Verfügung gestellt werden muss.With a commercially available burner, one Aperture unit used, in which the support legs part of a Carrier are, which consists of two side parts, which by two rings spaced from each other are connected. The joints of the side parts with the The cover and the rings are welded. On one of the two Steitenteile is a mounting plate welded, which is used to attach the ignition electrodes. When assembling the Brenners the aperture unit is placed on the nozzle rod and clamped to it by a screw. This Aperture unit consists of relatively cheap stamped parts. The disadvantage, however, is the relatively large production outlay. As already mentioned, the rings, the side parts, the Mounting plate for the ignition electrodes and the panel through a large number of welding points connected to one another. This first requires that the parts be oiled and Grease residues are freed up so that they are flawless Weld can arise. In practice, however showed that despite pre-cleaning the parts, the welds are often faulty and not under stress withstand. Another disadvantage is that the parts be precisely aligned prior to the welding operation have to. Because of the large number of welds, the final check of the completed unit very much complex. These individual work steps add up a considerable amount of work to reduce is of particular importance because the aperture unit in relative large quantities must be made available.

Es ist deshalb Aufgabe der vorliegenden Erfindung, eine Blendeneinheit zur Verfügung zu stellen, die einfacher, kostengünstiger und mit einem geringeren Arbeitsaufwand als die eingangs erwähnten Blendeneinheiten herzustellen ist. Die Verbindungen zwischen den einzelnen Teilen der Einheit sollten stabil sein, sodass keine Gefahr von Bruchstellen besteht. Es wäre zudem wünschenswert, wenn praktisch nach der Fabrikation praktisch keine Nachkontrolle mehr nötig wäre und die Blendeneinheit weitgehend automatisch hergestellt werden könnte.It is therefore an object of the present invention to To provide aperture unit which is easier cheaper and with less work than that panel units mentioned above is to be produced. The Connections between the individual parts of the unit should be stable so that there is no risk of breakage. It would also be desirable if practically after fabrication practically no follow-up inspection would be necessary and the Aperture unit are largely automatically produced could.

Dies wird erfindungsgemäss dadurch erreicht, dass die Befestigungsmittel durch einen U-förmigen Bügel gebildet sind, dessen Arme quer zur Längsachse der Blendeneinheit angeordnet sind, dass ein Arm des U-förmigen Bügels auf jeder Seite mindestens eine Einstecköffnung aufweist, in welcher ein Zapfen des Seitenteils eingreift, dass jeder Seitenteil mindestens eine Einstecköffnung aufweist, in welche ein Zapfen eingreift, der sich vom anderen Arm des U-förmigen Bügels seitlich nach aussen erstreckt, und dass die Blende mit den Seitenteilen verbunden ist. Da die Arme des Bügels quer zur Längsachse angeordnet sind, greifen die Zapfen der Seitenteile praktisch parallel zur Längsachse in die Einstecköffnungen am einen Arm des Bügels ein. Die Zapfen des anderen Arms des Bügels greifen dagegen quer zur Längsachse der Blendeneinheit in die Seitenteile ein und verhindern so, dass die Zapfen der Seitenteile aus den Einstecköffnungen des erstgenannten Arms bewegt werden können. Nach dem Zusammenbau der Teile, also sobald die Seitenteile mit der Blende verbunden sind, entsteht ein stabiles Gebilde. Es entfällt somit ein aufwendiges Reinigen und unsicheres Vereinigen von zusammenzuschweissenden Seitenteilen, wie dies einleitend beschrieben wurde. Auch sind keine Justier- und abschliessenden Kontrollarbeiten mehr nötig, da die geometrische Anordnung der Teile durch die Zapfen und Einstecköffnungen fest vorgegeben ist. Die Blendeneinheit kann daher durch angelerntes Personal zusammengebaut werden. Die Montage ist äusserst einfach. Die Seitenteile werden leicht schräge nach aussen geneigt in den U-förmigen Bügel gesteckt, dann gegeneinander nach innen verschwenkt, so dass die Zapfen des Bügels in die Einstecköffnungen der Seitenteile eingreifen, worauf das so entstandene Gebilde auf geeignete Art an der Blende befestigt wird. Diese Montage lässt sich bei grossen Stückzahlen auch automatisieren. Es ist zweckmässig, wenn die Seitenteile jeweils zwei in Abstand voneinander angeordnete Zapfen aufweisen, welche in entsprechende Einstecköffnungen am Arm eingreifen. Dies ergibt eine besonders stabile Anordnung.This is achieved according to the invention in that the Fasteners are formed by a U-shaped bracket, the arms of which are arranged transversely to the longitudinal axis of the diaphragm unit are that one arm of the U-shaped bracket on each side has at least one insertion opening in which a pin of the side part engages that each side part at least has an insertion opening into which a pin engages, which extends laterally from the other arm of the U-shaped bracket extends outside, and that the bezel with the side panels connected is. Because the arms of the bracket are transverse to the longitudinal axis are arranged, the pins of the side parts grip practically parallel to the longitudinal axis in the insertion openings on one arm of the bracket. Grip the pins of the other arm of the bracket in contrast, transversely to the longitudinal axis of the aperture unit in the Side parts and thus prevent the pins of the Side parts from the insertion openings of the former arm can be moved. After assembling the parts, so as soon as the side parts are connected to the bezel a stable structure. An elaborate process is therefore eliminated Cleaning and unsafe joining of welded parts Side parts, as described in the introduction. Also are no adjustment and final inspection work necessary, because the geometrical arrangement of the parts by the pins and Insertion openings is fixed. The aperture unit can therefore be assembled by trained personnel. The Assembly is extremely easy. The side parts become light inserted obliquely outwards into the U-shaped bracket, then pivoted towards each other inwards so that the peg of the bracket engage in the insertion openings of the side parts, whereupon the resulting structure is suitably attached to the Aperture is attached. This assembly can be done with large Automate quantities too. It is useful if the Side panels each two spaced apart Have pins which in corresponding insertion openings on Intervene arm. This results in a particularly stable arrangement.

Im Gegensatz zu den Stützbeinen der Blendeneinheit gemäss der CH-A-654 900, welche lediglich an einer Stelle mit dem vorderen Teil der Befestigungsbuchse verbunden sind, sind die Seitenteile der erfindungsgemässen Blendeneinheit nicht nur mit einem Arm sondern mit beiden Armen des U-förmigen Bügels verbunden, welcher der Befestigung der Blendeneinheit dient. Die Seitenteile können daher nicht leicht verbogen werden. Somit besteht auch keine Gefahr, dass die Blende exzentrisch zur Brennerachse zu liegen kommt. Vorteilhaft ist auch, dass der U-förmige Bügel als Träger für die Zündelektrode dienen kann. Dadurch wird deren Auswechslung bei Servicearbeiten erleichtert.In contrast to the support legs of the panel unit according to the CH-A-654 900, which is only in one place with the front Part of the mounting bush are connected Side parts of the panel unit according to the invention not only with one arm but with both arms of the U-shaped bracket connected, which is used to attach the panel unit. The side parts can therefore not be bent easily. So there is no risk that the aperture is eccentric comes to lie on the burner axis. It is also advantageous that the U-shaped bracket serve as a support for the ignition electrode can. This makes their replacement during service work facilitated.

Vorteilhaft weisen die Seitenteile Zapfen auf, welche in Einsteckschlitze der Blende steckbar sind, wobei eine Fixierung z.B. durch Verdrehen oder Vernieten der Zapfen erfolgen kann. Dadurch können die Seitenteile ebenfalls ohne Schweissen mit der Blende verbunden werden. Zweckmässigerweise weisen die Arme des U-förmigen Bügels in der Längsachse des Brenners jeweils eine Oeffnung auf, welche der Befestigung der Blendeneinheit im Brenner dient. Die Blendeneinheit kann auf die Düsenstanger das Lager für einen rotierenden Vergaser oder einen Support aufgesteckt werden. Die Seitenteile weisen zweckmässigerweise eine Gewindebohrung auf, in welche eine Schraube zur Fixierung der Blendeneinheit eindrehbar ist. Die Blendeneinheit lässt sich dadurch einfach und schnell im Brenner befestigen.The side parts advantageously have pins which are in Insert slots of the panel are plugged in, with a fixation e.g. can be done by twisting or riveting the pins. This means that the side parts can also be welded without the aperture can be connected. The arms expediently point of the U-shaped bracket in the longitudinal axis of the burner in each case an opening on which of the attachment of the panel unit in Burner serves. The aperture unit can do this on the nozzle rod Bearings for a rotating carburetor or support be plugged on. The side parts expediently have a threaded hole in which a screw for fixation the panel unit can be screwed in. The aperture unit leaves can be easily and quickly attached to the burner.

Vorteilhaft weisen die Seitenteile abgewinkelte Flügel auf. Dadurch werden die Seitenteile vertieft und zudem kann der Blendenträger in seinen Abmessungen relativ klein gehalten werden. Es verbleibt auch genügend Platz, um z.B. die Zündelektroden am Träger zu befestigen oder eine Brennstoffzuführungsleitung am Träger vorbei zu führen. Es ist zweckmässig, dass der Bügel einen Steg mit einer Gewindebohrung aufweist, um der Fixierung der Zündelektroden zu dienen. Die Schraube, mit welcher die Zündelektrode befestigt sind, ist leicht zugänglich, was das Auswechseln der Zündelektroden bei Servicearbeiten erleichtert. Es muss somit im Gegensatz zum vorbekannten Stand der Technik kein zusätzliches Halteblech an eines der Seitenteile geschweisst werden.The side parts advantageously have angled wings. This deepens the side panels and can also The size of the aperture support is kept relatively small will. There is also enough space to e.g. the To attach ignition electrodes to the carrier or a Guide the fuel supply line past the carrier. It is expedient that the bracket has a web with a threaded hole has to serve to fix the ignition electrodes. The Screw with which the ignition electrode is attached easily accessible, which means replacing the ignition electrodes Service work made easier. In contrast to the known prior art no additional retaining plate one of the side parts is welded.

  • Die Figuren 1 bis 5 zeigen eine erfindungsgemässe Blendeneinheit 11, welche aus einer Blende 13 und einem Blendenträger 18 mit zwei identischen Seitenteilen 15 und einem U-förmigen Bügel 17 besteht. Im Gegensatz zum Stand der Technik sind die Einzelteile des Blendenträgers einfach zusammengesteckt. Dies wird dadurch erreicht, dass ein U-förmiger Bügel 17 die Seitenteile 15 verbindet. Der Bügel 17 weist an einem Arm 19 Einstecköffnungen 23 auf, in welche die Zapfen 27 der Seitenteile 15 eingreifen können. Der andere Arm 21 des Bügels 17 weist an den Seitenkanten jeweils einen Zapfen 25 auf, welcher in eine Einstecköffnung 29 am Seitenteil 15 eingreift. Zur Montage des Blendenträgers werden die Zapfen 27 in die Einstecköffnungen 23 gesteckt und die Seitenteile 15 anschliessend gegen den Bügel 17 geschwenkt, sodass die Zapfen 25 ebenfalls in die Einstecköffnungen 29 eingreifen. Nach der Fixierung der Seitenteile 15 an der Blende 13 sind die Seitenteile 15 mittels des Bügels 17 fest miteinander verbunden und bilden so den Blendenträger 18.Figures 1 to 5 show an inventive Aperture unit 11, which consists of an aperture 13 and a Aperture support 18 with two identical side parts 15 and one U-shaped bracket 17 is made. In contrast to the state of the art the individual parts of the panel support are simple put together. This is achieved by having a U-shaped Bracket 17 connects the side parts 15. The bracket 17 has on one arm 19 insertion openings 23 into which the Pins 27 of the side parts 15 can engage. The other arm 21 of the bracket 17 has a pin on the side edges 25, which in an insertion opening 29 on the side part 15th intervenes. To mount the panel support, the pins 27 inserted into the insertion openings 23 and the side parts 15 then pivoted against the bracket 17 so that the pin 25 also engage in the insertion openings 29. After Fixing the side parts 15 to the panel 13 are the Side parts 15 firmly connected to each other by means of the bracket 17 and thus form the panel support 18th

    Zur Befestigung des Blendenträgers 18 an der Blende 13 weisen die Seitenteile 15 Zapfen 33 (Fig.2) auf, welche in Einsteckschlitze 35 an der Blende 13 eingreifen. Wie aus den Figuren 1,3,4b,c ersichtlich ist, haben die Seitenteile 15 abgewinkelte Flügel 31. Die Zapfen 33 werden, nachdem sie in die Einsteckschlitze 35 gesteckt worden sind, durch Umbiegen oder durch Verdrehen mit einer Zange oder einem Spezialwerkzeug an der Blende 13 fixiert. Die Blendeneinheit lässt sich somit ohne Justier-, Schweiss- und Kontrollarbeiten zusammenbauen.To fasten the panel support 18 to the panel 13 the side parts 15 pin 33 (Fig.2), which in Insert slots 35 on the panel 13. Like from the Figures 1,3,4b, c can be seen, have the side parts 15 angled wings 31. The pins 33, after they are in the insertion slots 35 have been inserted by bending or by twisting with pliers or a special tool fixed to the aperture 13. The aperture unit can thus be assemble without adjustment, welding and inspection work.

    Die Arme 19,21 des Bügels 17 weisen je eine Oeffnung 41,41' auf, welche der Befestigung der Blenden- oder Stauscheibeneinheit 11 im Brenner dient. Die Blendeneinheit 11 kann mittels der Oeffnungen 41,41' auf eine in der Längsachse des Brenners sich erstreckende Düsenstange oder dergleichen gesteckt und anschliessend durch eine Schraube, welche in eine Gewindebohrung 43 am Seitenteil 15 eingedreht wird, fixiert werden.The arms 19, 21 of the bracket 17 each have an opening 41, 41 ' on which of the attachment of the aperture or Baffle plate unit 11 is used in the burner. The aperture unit 11 can by means of the openings 41, 41 'on one in the longitudinal axis of the burner extending nozzle rod or the like inserted and then by a screw, which in a Threaded hole 43 is screwed into the side part 15, fixed will.

    Der die beiden Arme 19,21 verbindende Steg 37 des Bügels 17 kann der Fixierung von für den Betrieb des Brenners nötigen Zuleitungen, z.B. der Zündelektroden, dienen. Zu diesem Zweck ist der Steg 37 als Befestigungsplatte ausgebildet und weist eine Gewindebohrung 39 für eine Schraube (nicht dargestellt) auf. Die von einer Isolation umgebenen Zündelektroden können mittels eines Halteplättchens direkt an der Blendeneinheit fixiert werden.The web 37 of the bracket 17 connecting the two arms 19, 21 may require fixation for the operation of the burner Supply lines, e.g. the ignition electrodes. To this end the web 37 is designed as a mounting plate and has a threaded hole 39 for a screw (not shown) on. The ignition electrodes surrounded by insulation can by means of a holding plate directly on the panel unit be fixed.
