Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bekanntlich bildet sich an der Schweißstelle des Rohrschusses Schlacke, die vor Vornahme des Schweißprozesses entfernt werden muß. Dies soll die nachbeschriebene Vorrichtung bewirken. Nun ist zwar eine Vorrichtung zur Entfernung des überflüssigen Lots auf Rohren mit gelöteter Längsnaht bekannt geworden, bei welcher ein unter regulierbarer Federspannung stehender Meißel oder ein rotierender Fräser zur Anwendung kommt. Bei dieser steht der unter Federwirkung stehende Meißel mit dem Rohre in ständiger Verbindung bzw.As is well known, slag forms at the welding point of the pipe section, which before it is carried out must be removed during the welding process. The device described below is intended to achieve this. Now, although a device for removing the superfluous solder on pipes with a soldered longitudinal seam has become known, in which a chisel under adjustable spring tension or a rotating one Milling cutter is used. In this case, the chisel, which is under the action of a spring, stands in constant contact with the pipe or
k in ständiger Berührung.k in constant contact.
* Hiervon unterscheidet sich die Schlacken-* This differs from the slag
kratzvorrichtung gemäß der vorliegenden Erfindung insofern, als bei derselben mehrere angeschärfte Kratzeisen auswechselbar in einem schlittenartigen Rahmen befestigt sind und letzterer durch Winkelhebel, die durch Zugkette und Hebel bewegt werden, hin und her bewegt werden kann, bei welcher Bewegung die Kratzeisen innen mit dem Rohrschuß in Berührung kommen und die hier befindliche Schlacke abkratzen. Die Berührung der Kratzeisen mit dem Rohrschusse ist daher keine ständige, sondern sie läßt sich nach Belieben von außen herbeiführen.Scratching device according to the present invention insofar as the same several Sharpened scrapers are replaceably fastened in a slide-like frame and the latter by angle levers that are moved by pull chain and lever back and forth can be moved, with which movement the scraper inside with the pipe section in Come into contact and scrape off the slag located here. The touch of the scraper with the pipe shot is therefore not a permanent one, but it can be done at will bring about from the outside.
Die Schlackenkratzvorrichtung ist auf der Zeichnung in einer Ausführungsform zur Darstellung gebracht, und zwar in Fig. -1 im Längsschnitt, in Fig. 2 in Draufsicht und in Fig. 3 im Querschnitt.The slag scraper device is shown in one embodiment in the drawing brought, namely in Fig. -1 in longitudinal section, in Fig. 2 in plan view and in 3 in cross section.
Die Wind- und Gasleitung a, b führt in bekannter Weise zum Brenner c, während auf dem Vorhalter d der Schweißprozeß mittels beliebiger Vorrichtungen bewirkt wird.The wind and gas lines a, b lead in a known manner to the burner c, while the welding process is effected on the holder d by means of any devices.
Um vor dem Schweißprozeß die Schlacke an der Innenseite des Rohrschusses e zu entfernen, dient die Schlackenkratzvorrichtung, deren Rahmen g mehrere auswechselbare, angeschärfte Kratzeisen f enthält. Mit dem Rahmen sind die Winkelhebel h und i gelenkig verbunden, die durch das Gußstück k miteinander verbunden sind. Bewegt wird die Vorrichtung von außen durch eine Kette /, die ihren Antrieb durch einen Hebel erhält. In Ruhestellung befinden sich die Kratzeisen f mit dem Rohrschuß e nicht in Berührung, sondern stehen etwas ab. Erst wenn an der Kette I ein Zug ausgeübt wird, schwingen die Winkelhebel h und i um ihre am Maschinengestell vorgesehenen Drehzapfen und drücken, die Kratzeisen f von unten gegen die Schweißnaht. In order to remove the slag on the inside of the pipe section e before the welding process, the slag scraper device, the frame g of which contains several exchangeable, sharpened scraping irons f , is used. The angle levers h and i , which are connected to one another by the casting k, are articulated to the frame. The device is moved from the outside by a chain /, which is driven by a lever. In the rest position, the scrapers f are not in contact with the pipe section e , but protrude somewhat. Only when a pull is exerted on the chain I do the angle levers h and i swing around their pivot pins provided on the machine frame and press the scraper f from below against the weld seam.
Hört die Zugwirkung an der Kette I auf, so fällt der Rahmen g samt den Kratzeisen durch sein Eigengewicht in Ruhestellung zurück. If the pulling effect on the chain I ceases, the frame g, including the scraper, falls back into the rest position due to its own weight.
