Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung einer Lötverbindung zwischen sich überlappenden Dachrinnenteilen.The invention relates to a method and a device for producing a soldered connection between overlapping gutter parts.

Dachrinnenteile aus NE-Metallen, verzinktem Stahl, insbesondere Zink oder Zinklegierungen, werden im allgemeinen durch Löten in ihren überlappungsbereichen miteinander verbunden, wobei es bei der Verwendung von verzinktem Stahl erforderlich ist, die Dachrinnenteile vor dem Löten durch Nieten miteinander zu verbinden. Beim Löten selbst arbeitet man meistens mit dem Lötkolben. Bevorzugt wird ein kupferner Kolben in Spitz- oder Hammerform. Zur Entfernung von Oxyden und Lotresten wird die heiße Spitze oder Schneide des Lötkolbens auf Salmiakstein abgerieben; dann bringt man Lötzinn auf den Salmiakstein und reibt den Lötkolben solange darauf ab, bis sich die Arbeitsfläche des Lötkolbens gut verzinnt hat. Auf den vorher mit Flußmittel behandelten Überlappungsbereich wird das Lötzinn mit dem Lötkolben aufgetragen. Das Lot soll dem Lötkolben nachfließen. Die Überlappung bei der Dachrinnenlötung beträgt mindestens 10 mm; bei der Lötverbindung der Dachrinne mit einem Rinnenendstück mindestens 4 mm. Die zu lötenden Flächen sollen dicht aneinanderliegen, so daß eine möglichst dünne Lotschicht, die eingeschwemmt wird, die Verbindung herstellt. Während der Lötung und bis zur Erstarrung des Lotes müssen die zu verbindenden Teile festgehalten oder eingespannt bleiben. Damit das eingeschwemmte Lot erstarren kann, muß der Lötvorgang immer dann unterbrochen werden, wenn eine der Breite des Lötkolbens von z.B. 30 mm entsprechende Länge der Lötnaht hergestellt worden ist.Gutter parts made of non-ferrous metals, galvanized steel, in particular zinc or zinc alloys, are generally connected to one another by soldering in their overlap areas, and when using galvanized steel it is necessary to connect the gutter parts to one another by riveting before soldering. When soldering itself, you usually work with the soldering iron. Is preferred a copper piston in a pointed or hammer shape. To remove oxides and solder residues, the hot tip or cutting edge of the soldering iron is rubbed onto ammonia stone; then you put solder on the ammonia stone and rub the soldering iron on it until the working surface of the soldering iron has tinned well. The solder with the soldering iron is applied to the overlap area previously treated with flux. The solder should flow after the soldering iron. The overlap in gutter brazing is at least 10 mm; when soldering the gutter to a gutter end piece at least 4 mm. The surfaces to be soldered should lie close together so that the thinest possible solder layer that is washed in creates the connection. During soldering and until the solder solidifies, the parts to be connected must be held or clamped. So that the solder that has washed in can solidify, the soldering process must be interrupted whenever a length of the soldered seam corresponding to the width of the soldering iron, for example 30 mm, has been produced.

Für die Beheizung des Kolbens wird heute vor allem Propangas, daneben auch Butangas verwendet.Today, mainly propane gas is used to heat the piston, but also butane gas.

Die Festigkeit der Lötverbindung hängt jeweils im wesentlichen von der Form der Naht im Überlappungsbereich und der Gleichmäßigkeit der Lötung ab.The strength of the solder joint essentially depends on the shape of the seam in the overlap area and the uniformity of the soldering.

Aus den vorstehenden Ausführungen ergibt sich, daß die beim Verbinden von Dachrinnen durch Löten notwendigen Arbeiten nicht nur mit einer Reihe zeitaufwendiger, teilweise umständlicher, manueller Tätigkeiten, sondern auch mit einem vergleichsweise großen Lötzinnverbrauch von 30 bis 80 g/m hergestellte Lötnaht verbunden sind. Hinzu kommt, daß bei Verwendung von besonderen Flußmitteln die Flußmittelreste nach dem Löten sorgfältig entfernt werden müssen, um Korrosionserscheinungen zu. vermeiden.From the above, it follows that the work required when connecting gutters by soldering is not only associated with a series of time-consuming, sometimes cumbersome, manual tasks, but also with a comparatively large soldering consumption of 30 to 80 g / m of soldered seam. In addition, when using special fluxes, the flux residues must be carefully removed after soldering in order to prevent corrosion. avoid.

Aufgabe der vorliegenden Erfindung ist die Entwicklung einer verbesserten Möglichkeit zur Herstellung der Lötverbindungen zwischen Dachrinnenteilen in ihrem Oberlappungsbereich.The object of the present invention is to develop an improved possibility for producing the soldered connections between gutter parts in their overlap area.

Die Lösung dieser Aufgabe besteht darin, daß zwischen den sich überlappenden Dachrinnenteilen ein Lot deponiert, vorzugsweise jedoch ein Lotband eingelegt und anschließend die Dachrinnenteile im Überlappungsbereich entlang ihrer Profillinie, wenigstens vom Bereich des Wulstes bis zum Wasserfalz, mechanisch aufeinandergepreßt und im Überlappungsbereich erwärmt werden.The solution to this problem is that a solder is deposited between the overlapping gutter parts, but preferably a solder tape is inserted, and then the gutter parts in the overlap area along their profile line, at least from the area of the bead to the water fold, are mechanically pressed together and heated in the overlap area.

Die Vorrichtung zur Durchführung dieses Verfahrens besteht aus zwei gegeneinander preßbaren Spannbacken, deren dem Profil der Dachrinnenteile im Überlappungsbereich angepaßte Spannflächen in der Preßstellung parallel zueinander verlaufen.The device for carrying out this method consists of two clamping jaws which can be pressed against one another, the clamping surfaces of which, adapted to the profile of the gutter parts in the overlap region, run parallel to one another in the pressing position.

Die innere Spannbacke ist schwenkbar mit einer Spindel verbunden, die in einem mit der äußeren Spannbacke verbundenen, höhenverstellbaren Spannbügel gelagert ist.The inner clamping jaw is pivotally connected to a spindle which is mounted in a height-adjustable clamping bracket connected to the outer clamping jaw.

Im Rahmen der besonderen Ausgestaltung der Vorrichtung ist die innere Spannbacke quer zur Längsrichtung der Dachrinnenteile verschieblich an der Spindel angeordnet, so daß sich ihr Druckpunkt in jeder Höhe des Spannbügels selbst einstellt.As part of the special design of the device, the inner clamping jaw is arranged on the spindle so as to be displaceable transversely to the longitudinal direction of the gutter parts, so that its pressure point sets itself at any height of the clamping bracket.

Bei einer anderen Ausführungsform der Spannvorrichtung ist die innere Spannbacke einseitig schwenkbar an der äußeren Spannbacke gelagert und in Spannstellung mit der äußeren Spannbacke über Spannelemente verspannbar.In another embodiment of the clamping device, the inner clamping jaw is pivotally supported on one side on the outer clamping jaw and can be clamped in the clamping position with the outer clamping jaw via clamping elements.

Um eine gute Wärmeleitung zu gewährleisten, ist wenigstens die Spannfläche der inneren Spannbacke kammartig gestaltet.In order to ensure good heat conduction, at least the clamping surface of the inner clamping jaw is designed like a comb.

Ein weiterer Vorteil für das Flammlöten ergibt sich, wenn im Bereich der Mitte der oberen Spannbacke ein Gasbrenner halbkreisförmig schwenkbar gelagert ist. Der Gasbrenner kann wechselseitig angebracht werden.Another advantage for flame brazing is obtained when a gas burner is pivoted in a semi-circular manner in the area of the center of the upper jaw. The gas burner can be attached alternately.

Die Erwärmung des Überlappungsbereichs erfolgt bei Anwendung des Flammlötens dadurch, daß die Flamme unmittelbar auf das Dachrinnenmaterial oder mittelbar auf die innere und/oder äußere Spannbacke gerichtet ist.When using flame brazing, the overlap area is heated by the flame being directed directly at the gutter material or indirectly at the inner and / or outer clamping jaw.

Es ist aber auch möglich, eine oder beide Spannbacken elektrisch aufheizbar zu gestalten.But it is also possible to make one or both jaws electrically heatable.

Die in den Zeichnungen beispielhaft dargestellte erfindungsgemäße Vorrichtung wird im folgenden näher beschrieben:

  • In Fig. 1 ist die perspektivische Ansicht einer Vorrichtung zur Herstellung der Lötverbindung von halbrunden Dachrinnenteilen dargestellt. Die im Oberlappungsbereich der Dachrinnenteile, die innenliegende Dachrinne erfassende, eine Erhöhung 1 zur Wasserfalzseite aufweisende Spannbacke 2 ist an der Spindel 3 schwenkbar und quer zur Längsrichtung der Dachrinnenteile verschieblich in dem Langloch 4 mit Hilfe des Kugelgelenks 5 gelagert. Die Spindel 3 ist in dem Spannbügel 6 drehbar gelagert. Der Spannbügel 6 ist auf einem mit der äußeren Spannbacke 7 fest verbundenen Führungsteil 8 verschiebbar angeordnet. In der Mitte der inneren Spannbacke 2 ist der Gasbrenner 9, dem über die Leitung 10 Gas zugeführt wird, schwenkbar angelenkt. Die Spannflächen 11, 12 der Spannbacken 2, 7 verlaufen in Spannstellung parallel.
The device according to the invention shown by way of example in the drawings is described in more detail below:
  • In Fig. 1, the perspective view of a device for producing the solder connection of semicircular gutter parts is shown. The clamping jaw 2 in the overlap area of the gutter parts, which detects the inner gutter and has an elevation 1 on the water rebate side, can be pivoted on the spindle 3 and is displaceable transversely to the longitudinal direction of the gutter parts in the slot 4 by means of the ball joint 5. The Spindle 3 is rotatably mounted in the clamping bracket 6. The clamping bracket 6 is arranged displaceably on a guide part 8 which is firmly connected to the outer clamping jaw 7. In the middle of the inner jaw 2, the gas burner 9, to which gas is supplied via the line 10, is pivoted. The clamping surfaces 11, 12 of the clamping jaws 2, 7 run parallel in the clamping position.

Die Fig. 2 zeigt eine weitere Ausführungsform der erfindungsgemäßen Vorrichtung, bestehend aus der die äußere Dachrinne im Überlappungsbereich der Dachrinnenteile fassenden Spannbacke 13 und der schwenkbar an dieser einseitig angelenkten, die innere Dachrinne im Überlappungsbereich fassenden Spannbacke 14, die mittels eines Kniehebelverschlusses 15 gegen die äußere Spannbacke 13 spannbar ist, indem der Bolzen 16 über den Hebel 17 hinter das gabelförmige Element 18 der äußeren Spannbacke 13 greift. Die Spannflächen 19, 20 der Spannbacken 13, 14 sind kammerartig ausgebildet.Fig. 2 shows a further embodiment of the device according to the invention, consisting of the outer gutter in the overlap area of the gutter parts and the clamping jaw 13 pivotally articulated on this, the inner gutter in the overlap region 14, which by means of a toggle lock 15 against the outer Clamping jaw 13 can be clamped by the bolt 16 engaging behind the fork-shaped element 18 of the outer clamping jaw 13 via the lever 17. The clamping surfaces 19, 20 of the jaws 13, 14 are chamber-like.

Die mit der Erfindung erzielten Vorteile bestehen darin, daß eine einfachere Handhabung, sicherere Lötverbindung durch größere Lötnahtbreite und -länge, verbesserte Wirtschaftlichkeit durch Lotersparnis sowie 50 %ige Zeiteinsparung und höhere Sicherheit für den Handwerker gewährleistet sind.The advantages achieved by the invention are that simpler handling, safer soldered connection due to larger solder seam width and length, improved economy through soldering savings as well as 50% time saving and higher security for the craftsman.
