Vorrichtung zum Geraderichten verbeulter Rohre. Patentiert im Deutschen Reiche vom 7. April 1921 ab.Device for straightening dented pipes. Patented in the German Empire on April 7, 1921 .
Dünnwandige Blechrohre, wie solche beispielsweise in den Bergwerken als Luttenrohre Verwendung finden, werden beim Transport von ihrem Herstellungsort bis zur Verwendungsstelle vielfach, besonders an den Enden, verbeult, so daß dieselben nicht mehr ineinandergeschoben werden können.Thin-walled sheet metal pipes, such as those in the mines as duct pipes Are used during transport from their place of manufacture to the point of use often dented, especially at the ends, so that they are no longer pushed into one another can be.
Die Aufgabe der vorliegenden Erfindung ist, eine Vorrichtung zu schaffen, vermittelsThe object of the present invention is to provide a device by means of
ίο welcher diese Rohre auf einfache Weise wieder gerichtet und verwendbar gemacht werden.ίο which these pipes again in an easy way directed and made usable.
Die Einrichtung nach der vorliegenden Erfindung besteht aus einem aus mehreren Gelenkstücken gebildeten Spannring, der mittels Schraube oder Keil in das Rohr eingespannt wird. Auch ist es möglich, einen Ring nach der vorliegenden Erfindung von innen in das Rohr zu spannen und einen anderen Ring gleichzeitig außen um das Rohr zu legen, wodurch eine doppelte Wirkung erzielt und das Rohr gleichsam wie durch eine Presse gerichtet wird. Es kann auch zweckmäßig sein, dem Vorgang des Richtens durch Hämmern von außen nachzuhelfen, wobei die Ringe nach und nach entsprechend strammer angespannt werden können.The device according to the present invention consists of one of several joint pieces formed clamping ring, which is clamped into the pipe by means of a screw or wedge. It is also possible to post a ring of the present invention to clamp from the inside into the pipe and another ring at the same time around the outside of the pipe, which has a double effect and that Pipe is straightened as it were through a press. It can also be useful help the process of straightening by hammering from the outside, with the rings after and can be tightened accordingly afterwards.
Der Gegenstand der Erfindung ist durch beiliegende Zeichnung im Aufriß und Grundriß dargestellt, α und b sind die gelenkig miteinander verbundenen Spannbacken, c ist das Rohr, in welches die Vorrichtung eingespannt ist. Die Einrichtung für das Spannen der Klemmbacken besteht bei der vorliegenden Ausführung beispielsweise aus zwei Mutterstücken d, welche in zwei gegenüberliegende Spannbacken gelenkig oder drehbar gelagert sind und in welche eine Schraube e, welche auf der einen Seite mit Rechtsgewinde und auf der anderen mit Linksgewinde versehen ist, eingeschraubt wird. Die Schraube hat etwa in der Mitte eine Verstärkung f, welche als Handgriff zum bequemeren Drehen der Schraube dienen soll und zu diesem Zwecke auch als Handrad ausgebildet sein kann. Als weitere Besonderheit der vorliegenden Ausführungsform ist die Herstellung aus normalem U-Eisen hervorzuheben. Hierdurch fällt die teure Schmiedearbeit fort, die Spannvorrichtung wird leichter und bietet infolge der günstigen Querschnittsform einen sehr hohen Widerstand. The object of the invention is shown by the accompanying drawing in elevation and plan, α and b are the hinged clamping jaws, c is the tube in which the device is clamped. The device for tensioning the clamping jaws in the present embodiment consists, for example, of two nut pieces d, which are articulated or rotatably mounted in two opposite clamping jaws and in which a screw e, which is provided on one side with a right-hand thread and on the other with a left-hand thread , is screwed in. The screw has a reinforcement f approximately in the middle, which is intended to serve as a handle for more convenient turning of the screw and can also be designed as a handwheel for this purpose. Another special feature of the present embodiment is that it is manufactured from normal U-iron. This eliminates the need for expensive forging, the clamping device is lighter and offers a very high resistance due to the favorable cross-sectional shape.
