Description
Die Erfindung betrifft eine Vorrichtung zur Herstellung einer Lötverbindung zwischen sich überlappenden Ender von Dachrinnenteilen, zwischen denen ein Lot deponiert, vorzugsweise ein Lotband eingelegt ist, bestehend aus zwei gegeneinander preßbaren Spannbacken, von denen die innere Spannbacke schwenkbar angelenkt ist und zwischen deren im verspannten Zustand parallel zueinander verlaufenden, dem Profil der Dachrinnenteile vom Wulst bis zum Wasserfalz im Bereich der sich überlappenden Enden angepaßten Spannflächen die sich überlappenden, auf Löttemperatur zu erwärmenden Enden aufeinander preßbar sind.The invention relates to a device for producing a soldered connection between overlapping ends of gutter parts, between which a solder is deposited, preferably a solder tape is inserted, consisting of two clamping jaws that can be pressed against one another, of which the inner clamping jaw is pivotably articulated and between them in the clamped state parallel mutually extending, the profile of the gutter parts from the bead to the water rebate in the region of the overlapping ends of the clamping surfaces, the overlapping ends to be heated to the soldering temperature can be pressed together.
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. A copper piston in a pointed or hammer shape is preferred. 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 the soldering and until the solder solidifies, the parts to be connected must be held or clamped. So that the washed-in solder can solidify, the soldering process must be interrupted whenever one of the width of the soldering iron, e.g. 30 mm corresponding length of the solder seam has been produced.
Für die Beheizung des Kolbens wird heute vor allem Propangas, daneben auch Butangas verwendet.Today, mainly propane gas and also butane gas are used to heat the piston.
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.From the foregoing, it follows that the work required to connect gutters by soldering is not only associated with a series of time-consuming, sometimes cumbersome, manual activities, but also with a comparatively large amount of soldering solder produced from 30 to 80 g / m.
Hinzu kommt, daß bei Verwendung von besonderen Flußmitteln die Flußmittelreste nach dem Löten sorgfältig entfernt werden müssen, um Korrosionserscheinungen zu vermeiden.In addition, if special fluxes are used, the flux residues must be carefully removed after soldering in order to avoid signs of corrosion.
Aus der US-PS 1 924 799 ist eine Vorrichtung zur Hersteliung einer Lötverbindung zwischen sich überlappenden Enden von Dachrinnenteilen bekannt, bei der die Dachrinnenteile zwischen zwei ihrem Profil entsprechende Spannbacken, von denen die innere an der äußeren schwenkbar angelenkt ist, einspannbar sind. Diese Lötvorrichtung hat sich wegen ihrer umständlichen Handhabung in der Praxis nicht durchsetzen können.From US-PS 1 924 799 a device for producing a soldered connection between overlapping ends of gutter parts is known, in which the gutter parts can be clamped between two jaws corresponding to their profile, of which the inner one is pivotally articulated to the outer one. This soldering device has not been able to prevail in practice because of its cumbersome handling.
Aufgabe der vorliegenden Erfindung ist die Entwicklung einer verbesserten Möglichkeit zur Herstellung der Lötverbindungen zwischen Dachrinnenteilen in ihrem Uberlappungsbereich.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 die innere Spannbacke schwenkbar mit einer Spindel verbunden und die Spindel in einem mit der äußeren Spannbacke verbundenen höhenverstellbaren Spannbügel gelagert ist.The solution to this problem is that the inner clamping jaw is pivotally connected to a spindle and the spindle 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.
Um eine gute Wärmeleitung zu gewährleisten, sollte wenigstens die Spannfläche der inneren Spannbacke kammartig gestaltet werden.In order to ensure good heat conduction, at least the clamping surface of the inner clamping jaw should be 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 kann bei Anwendung des Flammlötens dadurch erfolgen, 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 can be heated in that the flame is 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 der Zeichnung beispielhaft dargestellte erfindungsgemäße Vorrichtung wird im folgenden näher beschrieben:
- In der Fig. ist die perspektivische Ansicht einer Vorrichtung zur Herstellung der Lötverbindung von halbrunden Dachrinnenteilen dargestellt. Die im Überlappungsbereich 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 demSpannbügel 6 drehbar gelagert. DerSpannbügel 6 ist auf einem mit deräußeren Spannbacke 7 festverbundenen Führungsteil 8 verschiebbar angeordnet. In der Mitte derinneren Spannbacke 2 ist derGasbrenner 9, dem über dieLeitung 10 Gas zugeführt wird, schwenkbar angelenkt. DieSpannflächen Spannbacken
- In the figure, the perspective view of a device for producing the solder connection of semicircular gutter parts is shown. The in the overlap area of the gutter parts, the inner gutter grasping, an elevation 1 to the water
rebate side jaw 2 is pivotable on the spindle 3 and movable transversely to the longitudinal direction of the gutter parts in the Elongated hole 4 stored with the help of theball joint 5. The spindle 3 is rotatably mounted in theclamping bracket 6. Theclamping bracket 6 is slidably arranged on aguide part 8 which is firmly connected to theouter clamping jaw 7. In the middle of theinner jaw 2, thegas burner 9, to which gas is supplied via theline 10, is pivotably articulated. Theclamping surfaces clamping jaws
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.
