Die Erfindung betrifft Vorrichtungen zur Erzeugung von Ausbauchungen an Rohrstücken, bei denen auf die Stirnenden der Rohrstücke zwei Stauchfutter drücken und ein Dorn in das Rohrinnere eingesetzt ist. Die neue Erfindung besteht darin, daß die einander zugekehrten Seiten der Stauchfutter gegen die Längsachse nach einer oder mehreren Seiten schräg verlaufen. Beim Zusammenpressen der Stauchfutter tritt dann aus jeder zwischen den Futtern freibleibenden Öffnung eine Ausbauchung, aus der später ein Stutzen gezogen wird.The invention relates to devices for producing bulges on pipe sections, where two compression chucks press on the front ends of the pipe sections and a mandrel is inserted into the inside of the pipe. the new invention is that the facing sides of the edging run obliquely to the longitudinal axis on one or more sides. When pressing together the upset lining then emerges from every opening that remains free between the chucks a bulge from which later a nozzle is pulled.
Die Fig. I, 3 und 5 zeigen eine Vorrichtung zur Erzeugung eines Stutzens, Fig. 11 eine solche zur Erzeugung zweier Stutzen. Die Fig. 2, 4 und 6 stellen die Grundrisse der Werkstücke dar, deren Umformung aus Fig. I, 3 und 5 ersichtlich ist. Fig. 7 zeigt die fertig gepreßte Beule, Fig. 8 den ausgezogenen Stutzen, Fig. 9 und IO ein Rohranschlußstück mit aufgelöteten oder aufgenieteten Flanschen. Fig. 12 stellt ein Rohr mit zwei Stutzen dar, Fig. 13 ist die Seitenansieht dazu.Figs. I, 3 and 5 show an apparatus for producing one nozzle, FIG. 11 one for producing two nozzles. FIGS. 2, 4 and 6 represent the outlines of the workpieces, their deformation Fig. I, 3 and 5 can be seen. Fig. 7 shows the fully pressed bump, Fig. 8 the pulled out Nozzle, Fig. 9 and IO a pipe connector with soldered or riveted Flanges. Fig. 12 shows a pipe with two nozzles, Fig. 13 is the side view to.
Die Stauchfutter α und b, die zwischen sich das Rohrwerkstück e aufnehmen, sind an den einander zugewendeten Seiten abgeschrägt (Fig. i, 3 und 5). Sie besitzen eine Bohrung, die zur Aufnahme des Rohrwerkstückes dient, jedoch behufs Bildung eines Widerlagers abgesetzt ist. Die Fortsetzung der Bohrungen der beiden Futter ist von dem lichten Durchmesser des Rohres, so daß der in das Rohr eingesetzte Dorn d Führung in den kleinen Bohrungen der Stauchfutter α und b erhält.The upsetting chucks α and b, which take up the pipe workpiece e between them, are bevelled on the sides facing one another (FIGS. 1, 3 and 5). They have a hole that serves to accommodate the pipe workpiece, but is offset in order to form an abutment. The continuation of the bores of the two chucks depends on the inside diameter of the pipe, so that the mandrel inserted into the pipe receives d guidance in the small bores of the upsetting chuck α and b.
Durch das Zusammenführen der Stauchfutter erfährt das Rohrwerkstück e die aus den Fig. 3, 5 und 7 ersichtlichen Umformungen. Die gegenüber der Beule f entstehende Verdickung g wird durch Hämmern oder Pressen entfernt und dann die Beule f in bekannter Weise durch Aufbohren und Ausziehen zu einem Stutzen umgestaltet.By merging the edging feed the tube workpiece e undergoes apparent from Figs. 3, 5 and 7 transformations. The thickening g arising opposite the bulge f is removed by hammering or pressing and then the bulge f is redesigned into a socket in a known manner by drilling and pulling out.
Zwecks Erzeugung mehrerer Abzweigungen werden die Stauchfutter mit mehreren Abschrägungen versehen, von deren Größe es abhängt, ob die entstehenden Stutzen gleiche oder verschiedene Durchmesser erhalten (Fig. 11).In order to create several branches, the upset chucks are made with several bevels provided, the size of which determines whether the resulting nozzles have the same or different diameters (Fig. 11).
Die entstehende Beule besitzt eine größere Wandstärke als das Rohr, so daß der Stutzen
in unverschwächter Stärke ausgezogen
den kann.The resulting bulge has a greater wall thickness than the pipe, so that the socket is pulled out in an unsweaked strength
can.
