Description

Das bisher zum Stauchen von Rohrenden verwandte Gesenk ist zweiteilig ausgebildet, weil beim Stauchen das hinter der Stauchung befindliche Gesenkteil das Rohr zu spannen hat. Ein einteiliges Gesenk, durch das man das anzuspannende Rohr schieben müßte, könnte dieser Aufgabe infolgedessen nicht gerecht werden. Bei einer angestauchten Außenverdickung des Rohres kommt noch hinzu, daß diese im Durchmesser größer ist als der lichte Durchmesser des spannenden Gesenkteiles.The die previously used for upsetting pipe ends is in two parts formed because when upsetting the die part located behind the upsetting has to tension the pipe. A one-piece die through which you can clamp the Had to push pipe, this task could not be fair as a result. at an upset outer thickening of the pipe is also due to the fact that this is in diameter is larger than the clear diameter of the clamping die part.

Bei der Verwendung des zweiteiligen Gesenkes entstehen durch die Gesenknaht in Verbindung mit dem Atmen der Gesenhhälften am gestauchten Rohräußern zwei flössenartige Grate, die durch Schleifen oder Überdrehen beseitigt werden müssen.When using the two-part die, the die seam is created in connection with the breathing of the halves of the jaw on the compressed tube exterior, two raft-like Burrs that need to be removed by grinding or turning.

Gemäß der Erfindung wird dieser Nachteil bei gleichzeitiger Aufrechterhaltung der für das Spannen des Rohres erforderlichen Voraussetzung dadurch vermieden, daß im Bereiche der Stauchung in das zweiteilige Gesenk' eine einteilige Hülse eingesetzt ist. Hierdurch wird die Stauchung nach außen von der Hülse begrenzt, die Begrenzung der inneren Stauchung erfolgt in der üblichen Weise durch den Stauchdorn. Das erfindungsgemäße Gesenk ist beispielsweise in Abb. i für Außenstauchung, in Abb. 2 für Innenstauchung dargestellt. a ist das zu stauchende Rohr, b das zweiteilige Gesenk, c die erfindungsgemäße einteilige Hülse, d der Stauchdorn.According to the invention, this disadvantage is while being maintained the prerequisite for tensioning the pipe avoided in that A one-piece sleeve is inserted into the two-part die in the area of the upsetting is. As a result, the compression is limited to the outside of the sleeve, the limitation the internal compression takes place in the usual way by the compression mandrel. The inventive Die is, for example, in Fig. I for external upsetting, in Fig. 2 for internal upsetting shown. a is the tube to be upset, b the two-part die, c the one according to the invention one-piece sleeve, d the upsetting mandrel.

Die Erfindung kann auch für andere Werkstücke als Rohre nutzbar>macht werden.The invention can also be used for workpieces other than tubes will.

Der Vorteil der Erfindung gegenüber dem Bekannten liegt bei der guten Maßhaltigkeit der in der erfindungsgemäßen Hülse gestauchten Rohrenden od. dgl. in der Ersparnis einer besonderen Nacharbeit des angestauchten Rohrendes bei gleichzeitiger Möglichkeit, die Spannung des Rohres in einfacher Weise durch Zusammen- und Auseinanderfallen der Gesenkhälften zu betätigen.The advantage of the invention over the known is the good Dimensional accuracy of the pipe ends compressed in the sleeve according to the invention or the like. in the saving of a special reworking of the upset pipe end while at the same time Possibility of tensioning the pipe in a simple manner by collapsing and falling apart to operate the die halves.
