Der Gegenstand vorliegender Erfindung ist ein Werkzeug, mit welchem man bei der Verlegung von Isolierrohren mit Metallmantel an Ort und Stelle Krümmer von beliebigem Radius, herstellen kann. Zu diesem Zwecke ist das Werkzeug als Zange ausgebildet; und zwar derart, daß die eine Maulhälfte b (Fig. 3 und 4) mit einer horizontal liegenden Rinne versehen ist, welche an dem der anderenThe subject of the present invention is a tool with which one can produce bends of any radius when laying insulating pipes with a metal jacket on the spot. For this purpose, the tool is designed as a pair of pliers; in such a way that one mouth half b (Fig. 3 and 4) is provided with a horizontally lying groove, which is on that of the other
ίο Maulhälfte zugewendeten Ende zu einem vollständigen Ring ergänzt ist. In diesen wird das zu biegende Rohr eingelegt. Die andere Maulhälfte, in Fig. 1 und 2 dargestellt, trägt eine Rolle c, deren Höhlung dem Durchmesser des zu biegenden Rohres entspricht. Die Rinne mit dem den Ring ergänzenden Teil, sowie die Rolle c können ausgewechselt werden, so daß man Rohre von beliebigem Durchmesser biegen kann. Beim Zusammenpressen der Zangenschenkel h h wird das Rohr an der Stelle, wo es in den Ring tritt, geknickt und das überschüssige Material tritt in Gestalt einer Falte nach außen heraus, wie das aus Fig. 5 ersichtlich. Infolgedessen lassen sich Krümmungen von sehr kleinem Radius herstellen, ohne daß eine Verengerung des Rohrquerschnittes eintritt.ίο the end facing half of the mouth is completed to form a complete ring. The pipe to be bent is inserted into this. The other half of the mouth, shown in Fig. 1 and 2, carries a roller c, the cavity of which corresponds to the diameter of the pipe to be bent. The channel with the part complementing the ring, as well as the roller c can be exchanged so that pipes of any diameter can be bent. When the pliers legs hh are pressed together , the tube is kinked at the point where it enters the ring and the excess material emerges outward in the form of a fold, as can be seen from FIG. As a result, curvatures of a very small radius can be produced without the pipe cross-section becoming narrowed.
Eine Schraube .? (Fig. 4) gestattet, den Hub der Schenkel zu begrenzen und damit die Stärke der Knickung für beliebige Krümmungsradien festzulegen.A screw .? (Fig. 4) allows the hub to limit the leg and thus the strength of the kink for any radii of curvature to be determined.
