Verfahren und Vorrichtung zur Herstellung von Biegungen, insbesondere Doppelbiegungen, an Rohren.Method and device for producing bends, in particular double bends, on pipes.

Patentiert im Deutschen Reiche vom 9. August 1921 ab.Patented in the German Empire on August 9, 1921.

Die Erfindung betrifft ein Verfahren zur j Herstellung von Biegungen, insbesondere Doppelbiegungen, an Rohren, bei denen die Rohrschenkel nahe beieinander zu liegen kommen bzw. na/he beieinander liegen können und besteht im wesentlichen darin, daß das zu biegende Rohr zu 'beiden Seiten der Biegestelle gefaßt und derart festgehalten wird, daß bei dem Schwenken der Rohrenden zurThe invention relates to a method for the production of bends, in particular Double bends, on pipes where the pipe legs are close together can come or lie close to one another and essentially consists in the fact that the the pipe to be bent is gripped on both sides of the bending point and held in place in such a way that when pivoting the pipe ends to

ίο Herstellung der Biegung innerhalb dieser ein Stauchen (des Rohres eintritt.ίο making the bend within this one Upsetting (of the pipe occurs.

In der Zeichnung ist eine Vorrichtung zur Ausübung des Verfahrens in einer Ausführungsform beispielsweise dargestellt.In the drawing is a device for performing the method in one embodiment for example shown.

Die Vorrichtung besteht aus zwei Platten D1 D1, zwischen denen um Bolzen C1 C1 drehbar die Hebel B, B1 gelagert sind. An den Hebeln B1 B1 befinden sioh verstellbare Anschläge bzw. Schellen oder Klam-The device consists of two plates D 1 D 1 , between which the levers B, B 1 are mounted rotatably about bolts C 1 C 1. There are adjustable stops or clamps or clamps on levers B 1 B 1.

ao mern A1 Ax, mittels denen das zu biegende Rohr an den Hebeln B1 B1 festgespannt wer- j den kann. Die Hebel B, B1 sind an ihren Längsseiten mit halbrunden Nuten versehen, welche der Rohrdicke entsprechen, und die Platten D1D1 befinden sich in einer der Rohrdicke entsprechenden Entfernung voneinander. ao mern A 1 A x , by means of which the pipe to be bent can be clamped to the levers B 1 B 1 . The levers B, B 1 are provided on their long sides with semicircular grooves which correspond to the pipe thickness, and the plates D 1 D 1 are located at a distance from one another corresponding to the pipe thickness.

Zur Herstellung eines Doppelbogens wind das Rohr, welches in bekannter Weise mit Sand gefüllt sein kann, an der zu biegenden Stelle erwärmt und mit Hilfe der Klammern A1A1 so gegen die Hebel B1B1 gespannt, daß eine Lageveräniderung des Rohres zu den Hebeln B, B1 ausgeschlossen ist, wonach die Hebel um ihre Drehpunkte C, C1 geschwenkt werden (s. Abb. 2). Hierbei biegt und staucht sich das Rohr zwischen den Drehpunkten, deren Entfernung der Größe des herzustellenden Bogens entsprechend gewählt wird, zu dem gewünschten Doppelbogen, ohne daß der Rohrquerschnitt störende Veränderungen erleidet ader in der Wandstärke geschwächt wird.To produce a double bend, the pipe, which can be filled with sand in a known manner, is heated at the point to be bent and clamped against the lever B 1 B 1 with the help of brackets A 1 A 1 so that a change in position of the pipe to the Levers B, B 1 is excluded, after which the levers are pivoted about their pivot points C, C 1 (see Fig. 2). Here, the pipe bends and compresses between the pivot points, the distance of which is selected according to the size of the bend to be produced, to form the desired double bend, without the pipe cross-section suffering disruptive changes or being weakened in the wall thickness.

Durch Anordnung eines verstellbaren Formstückes B an der Biegestelle kann man die Form der Biegung in einer dem Formstück entsprechenden Weise beeinflussen.By arranging an adjustable shaped piece B at the bending point, the shape of the bend can be influenced in a manner corresponding to the shaped piece.

Selbstverständlich lassen sich nach dem vorliegenden Verfahren auch beliebig andere Bogen oder Krümmungen an Rohren beispielsweise von mehr oder weniger als 900 herstellen. *, Any other arc or curvature can Of course, according to the present method of tubes, for example, of more or less than 90 0 produced. *
