Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung einer kraftschlüssigen Verbindung eines Futterrohres (3) mit dem Mantelrohr (2) einer Rohrwaffe durch Einschrumpfen.The invention relates to a method for producing a non-positive connection of a casing (3) with the Jacket tube (2) of a barrel weapon by shrinking.

Um die relativ langen und dünnwandigen Futterrohre (3) auf einfache Weise und sehr genau mit den Mantelrohren (2) entsprechender Rohrwaffen zu verbinden, schlägt die Erfindung vor, das Fügespiel zwischen Futter- und Mantelrohr (3,2) dadurch zu vergrößern, daß zusätzlich zu der Erwärmung des Mantelrohres (2) eine Abkühlung des Futterrohres (3) unter einen Wert von -50°C, vorzugsweise auf -70°C, vorgenommen wird.

Figure 00000001
In order to connect the relatively long and thin-walled casing pipes (3) in a simple and very precise manner with the casing pipes (2) of corresponding pipe weapons, the invention proposes to increase the joint play between the casing and casing pipe (3,2) in that additionally to heat the casing tube (2), the casing (3) is cooled below a value of -50 ° C, preferably to -70 ° C.
