Description

Die vorliegende Erfindung bezieht sich auf ein Kaltpressen und insbesondere auf ein Gesenk zur Herstellung einer an einem Ende nach innen eingezogenen Rohrmuffe durch Pressen aus einem ringförmigen Werkstück und besteht darin, daß zwecks Herstellung der Mußen in einem Arbeitsgänge der Durchmesser des Gesenkunterteiles oberhalb der die Absetzung herbeiführenden Krümlu mung größer ist als der Durchmesser des Gesenkoberteiles zuzüglich der doppelten Muffenrandstärke.The present invention relates to cold pressing and, more particularly, to a die for the production of a pipe socket drawn inwards at one end by pressing from an annular workpiece and consists in the fact that for the purpose of producing the leisure in one operation the Diameter of the lower part of the die above the Krümlu causing the deposition mung is larger than the diameter of the Die upper part plus double the sleeve edge thickness.

Die Vorteile eines derartigen Gesenkes liegen in der Einfachheit und in der Wirtschaftlichkeit der Herstellungsweise.The advantages of such a die are its simplicity and economy the manufacturing method.

In der Zeichnung ist gemäß Abb. 1 eine an sich bekannte Rohrmuffe ι veranschaulicht, welche die Rohrenden 2, 3 miteinander verbindet. Zwischen dem Rohr 2 und der Muffe ι ist eine Packung 4 vorgesehen, die infolge des eingezogenen freien Endes der Muffe ι einen besonders festen Halt erhält. Das Rohrende 3 und die Muffe 1 sind miteinander außen und innen verschweißt.In the drawing, 1 is a per se known pipe sleeve is shown in Fig. Illustrates ι which connects the pipe ends 2, 3 with each other. Between the pipe 2 and the sleeve ι a pack 4 is provided, which receives a particularly firm hold as a result of the retracted free end of the sleeve ι. The pipe end 3 and the socket 1 are welded together outside and inside.

Die Herstellung der Muffe erfolgt erfindungsgemäß nach den Abb. 2 bis 4. Zunächst wird ein Flacheisenring mit dem Durchmesser« gewalzt. Die Stoßstelle wird, falls es sich um ein Nahtrohr handelt, elektrisch stumpf geschweißt. Hierauf wird dieser Ring in einem Gesenk bearbeitet. Das Untergesenk 5 hat in seinem oberen Teil, d. h. oberhalb der Krümmung 7, den Durchmesser, den die Ausbuchtung der Muffe betragen soll, während das Obergesenk 6 oben den Durchmesser c erhält, den das freie, eingezogene Muffenende haben soll. Beim Pressen bzw. Weiten wird der Ring in seinem mittleren Teil an die Innenwand des Untergesenkes angedrückt, während der obere Rand der Muffe sich fest um das Öbergesenk legt.The sleeve is manufactured according to the invention as shown in FIGS. 2 to 4. First, a flat iron ring with a diameter is rolled. If it is a seam tube, the joint is butt-welded electrically. This ring is then processed in a die. The lower die 5 has in its upper part, ie above the curvature 7, the diameter which the bulge of the socket should be, while the upper die 6 at the top receives the diameter c which the free, drawn-in socket end should have. When pressing or widening, the middle part of the ring is pressed against the inner wall of the lower die, while the upper edge of the sleeve is firmly attached to the upper die.

Die Wirkungsweise beruht darauf, daß sich die geweitete Rohrmuffe einmal in ihrem mittleren Teil gegen das größere Gesenkoberteil anlegt, und daß andererseits infolge der Reibung des Preßstempels an der Muffeninnenfläche eine Art Vorspannung entsteht, die ein Einziehen des äußeren Muffenendes zur Folge hat.The mode of operation is based on the fact that the widened pipe socket is once in its middle Part against the larger die upper part applies, and that on the other hand due to the friction of the ram on the sleeve inner surface creates a kind of bias, which a Pulling in the outer socket end.
