Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer kraftschlüssigen Verbindung eines Futterrohres mit dem Mantelrohr einer Rohrwaffe durch Einschrumpfen. Aus der US 2 915 946 A ist ein derartiges Verfahren, wobei das Futterrohr auf eine Temperatur unterhalb -50°C abgekühlt wird, das Mantelrohr in dem Teilbereich, in dem es mit dem Futterrohr verbunden werden soll, auf eine Temperatur erwärmt wird die derart gewählt ist, daß sein Innendurchmesser größen ist als der Außendurchmesser des Futterrohres und das Futterrohr dann in das Mantelrohr eingeführt wird bekannt.The invention relates to a method for producing a non-positive connection of a casing with the Jacket tube of a barrel weapon by shrinking. Such a method is known from US Pat. No. 2,915,946 A, the casing pipe being cooled to a temperature below -50 ° C., the casing pipe being heated to a temperature in the partial region in which it is to be connected to the casing pipe, which is chosen in this way is known that its inner diameter is larger than the outer diameter of the casing and the casing is then inserted into the casing.

Um ausgeschossene Waffenrohre wieder bestimmungsgemäß verwenden zu können, ist es seit langem bekannt, die Rohre auszubohren und anschließend mit einem dünnen, nicht selbsttragenden Rohr auszufüttern (vgl. z.B. Rheinmetall "Waffentechnisches Taschenbuch" 7. unveränderte Auflage 1985, Düsseldorf 1980). Die Futterrohre werden mit dem Mantelrohr, z.B. durch Einschrumpfen, verbunden, wobei üblicherweise das Mantelrohr erwärmt und das Futterrohr durch Wasser gekühlt wird.To reuse the fired gun barrel as intended to be able to drill the pipes has long been known and then with a thin, not self-supporting To feed the pipe (see e.g. Rheinmetall "Weapons Paperback "7th unchanged edition 1985, Düsseldorf 1980). The casing pipes are with the casing pipe, e.g. by shrinking, usually the Jacket tube heated and the casing tube cooled by water becomes.

Insbesondere bei Verwendung von Futterrohren mit einem großen L/d-Verhältnis hat es sich als nachteilig erwiesen, daß bei Anwendung dieses bekannten Fügeverfahrens das Fügespiel zwischen Futter- und Mantelrohr sehr gering ist, weil beim Warmschrumpfen eine maximale obere Temperatur des Mantelrohres nicht überschritten werden darf. Anderenfalls besteht die Gefahr, daß der Eigenspannungszustand des entsprechenden Waffenrohres zerstört werden würde.Especially when using casing pipes with a large one L / d ratio has proven disadvantageous in that Application of this known joining process the joining game between the casing and the casing pipe is very small, because at Heat shrink a maximum upper temperature of the casing tube must not be exceeded. Otherwise there is a risk that the residual stress state of the corresponding gun barrel are destroyed would.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die relativ langen und dünnwandigen Futterrohre auf einfache Weise und sehr genau mit den Mantelrohren entsprechender Rohrwaffen zu verbinden.The present invention is based on the object relatively long and thin-walled casing pipes on simple Wise and very accurate with the jacket pipes accordingly Connect barrel weapons.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is solved by the features of claim 1. Disclose further advantageous refinements of the invention the subclaims.

Im wesentlichen liegt der Erfindung der Gedanke zugrunde, das Fügespiel zwischen Futter- und Mantelrohr dadurch zu vergrößern, daß zusätzlich zu der Erwärmung des Mantelrohres eine Abkühlung des Futterrohres unter einen Wert von -50°C, vorzugsweise auf -70°C, vorgenommen wird.Essentially, the invention is based on the idea that To increase the joint play between the casing and casing pipe, that in addition to the heating of the casing tube Cooling of the casing below a value of -50 ° C, preferably to -70 ° C.

Wird das Futterrohr beim Einbringen in das Mantelrohr zunächst noch weiter gekühlt, so verläuft der Schrumpfvorgang vorteilhafterweise zunächst entsprechend langsam, weil das erwärmte (schrumpfende) Mantelrohr zu keiner sofortigen wesentlichen Erwärmung des Futterrohres führt und damit auch keine stärkere Durchmesservergrößerung des Futterrohres bewirkt.If the casing is inserted into the casing pipe first cooled even further, the shrinking process proceeds advantageously slowly at first, because that heated (shrinking) casing pipe to no immediate leads to substantial heating of the casing and thus also no major increase in diameter of the casing causes.

Zur Abkühlung des Futterrohres wird dieses vorzugsweise mit Trockeneis gefüllt. Sofern dabei die Abkühlung nicht im Vakuum oder in einem mit Schutzgas gefüllten Raum erfolgt, muß aufgrund der in der Umgebung vorhandenen Luftfeuchtigkeit das Futterrohr während des Abkühlvorganges außenseitig mittels einer Isolierschicht geschützt werden. To cool the casing, this is preferably done with Dry ice filled. If the cooling is not in the Vacuum or in a room filled with protective gas, due to the humidity in the area outside of the casing during the cooling process be protected by an insulating layer.

Die Erwärmung und Abkühlung des Mantelrohres sollte bereichsweise steuerbar sein, derart, daß das Mantelrohr zunächst auf den mittleren Bereich des Futterrohres und erst nach einer vorgegebenen Zeit auch auf die verbleibenden Seitenbereiche des Futterrohres aufschrumpfbar ist.The heating and cooling of the jacket tube should be in some areas be controllable in such a way that the jacket tube first the middle area of the casing and only after one given time also on the remaining side areas the casing is shrink-fit.

In Fig.1 ist mit 1 ein Waffenrohr einer Panzerkanone bezeichnet, welches aus einem Mantelrohr 2 und einem dünnwandigen Futterrohr 3 besteht, welches innenseitig in einem hoch belasteten Teilbereich 4 (im folgenden auch als Fügebereich bezeichnet) des Mantelrohres 2 angeordnet und mit diesem durch Einschrumpfen verbunden ist.1, a weapon barrel of a tank cannon is designated by 1, which consists of a casing tube 2 and a thin-walled Casing tube 3 exists, which is highly loaded on the inside Subarea 4 (in the following also as a joining area designated) of the casing tube 2 and arranged with this is connected by shrinking.

Um das Futterrohr 3 mit dem Mantelrohr 2 erfindungsgemäß zu verbinden, wird zunächst das Futterrohr 3 senkrecht auf einen Fixierdorn 5 einer Standvorrichtung 6 mit Bodenplatte 7 aufgesetzt und ausgerichtet (Fig.2). Um das Futterrohr 3 vor Vereisung beim Abkühlen zu schützen, wird es mit Styroporblöcken 8 umgeben und oberseitig mit einer Styroporhaube 9 versehen.To the casing tube 3 with the casing tube 2 according to the invention connect, the casing 3 is first perpendicular to one Fixing mandrel 5 of a standing device 6 with base plate 7 placed on it and aligned (Fig.2). Around the casing 3 To protect icing when cooling, it is made with polystyrene blocks 8 surrounded and on the top with a polystyrene hood 9 Mistake.

Anschließend erfolgt die Befüllung des Futterrohres 3 mit Trockeneis 10 über ein Ansetzrohr 11. Der Fixierdorn 5, der ebenfalls eine durchgehende Bohrung 12 enthält, wird ebenfalls mit Trockeneis 10 gefüllt und gekühlt. Dadurch wird eine gleichmäßige Abkühlung über die gesamte Länge des Futterrohres 3 erreicht (je nach Wandstärke und Material des Futterrohres werden für eine gute Durchkühlung des Futterrohres auf ca. -70°C bis zu 3 Stunden benötigt).Then the casing 3 is filled with Dry ice 10 via an attachment tube 11. The fixing mandrel 5, the also contains a through hole 12 is also filled with dry ice 10 and cooled. This will uniform cooling over the entire length of the casing 3 reached (depending on the wall thickness and material of the The casing is used for a good cooling of the casing up to 3 hours at approx. -70 ° C).

Parallel zum Abkühlen des Futterrohres 3 kann mit dem Erwärmen des Mantelrohres 2 auf ca. 335°C (+/- 5°C) begonnen werden. Damit eine ausreichende Erwärmung des gesamten Fügebereiches 4 sicher gewährleistet ist, sollte der tatsächliche Erwärmungsbereich den Fügebereich 4 beidseitig um ca. 0,5 m überschreiten. Die Aufheizrate sollte etwa zwischen 20 und 30°C liegen, um eine genügende Durchheizung des Mantelrohres 2 zu ermöglichen, wobei sich eine induktive Erwärmung mittels einer entsprechenden Heizung 13 (Fig.3) in der Praxis als vorteilhaft erwiesen hat.Parallel to the cooling of the casing 3, heating can take place jacket tube 2 to approx. 335 ° C (+/- 5 ° C). This ensures sufficient heating of the entire joint area 4 is assured, the actual Heating area joining area 4 on both sides by approx. 0.5 m exceed. The heating rate should be between 20 and 30 ° C to ensure sufficient heating of the jacket tube 2 to enable, whereby inductive heating by means of a corresponding heater 13 (Fig.3) in practice as has proven advantageous.

Sind Mantelrohr 2 und Futterrohr 3 im gewünschten Zustand, wird das weiterhin erwärmte Mantelrohr 2 mit einer Hubvorrichtung 14 an seiner Mündung 15 angehoben und über das noch mit Styroporblock 8 umgebenen Ansetzrohr 11 und Futterrohr 3 positioniert. Dabei kann zur Vereinfachung der Positionierung am ladungsraumseitigen Ende 16 des Mantelrohres 2 ein spezieller Anführtrichter 17 angeordnet werden (Fig.3).If the casing pipe 2 and casing pipe 3 are in the desired condition, the further heated jacket tube 2 with a lifting device 14 raised at its mouth 15 and over that yet with attachment tube 11 and casing tube 3 surrounded by polystyrene block 8 positioned. This can help simplify positioning at the cargo space end 16 of the casing tube 2 special funnel 17 can be arranged (Fig.3).

Der Styroporblock 8 und das Ansetzrohr 11 werden dann entfernt, das Futterrohr 3 trocken gesäubert und leicht mit einem Feststoffschmierstoff, vorzugsweise Molybdändisulfid (MoS2), leicht benetzt. The polystyrene block 8 and the attachment tube 11 are then removed, the casing tube 3 is cleaned dry and lightly wetted with a solid lubricant, preferably molybdenum disulfide (MoS 2 ).

Anschließend wird das Mantelrohr 2 bis an das odere Ende 18 des Futterrohres 3 zur Überprüfung und evtl. Nachkorrektur der Positionierung heruntergelassen. Ist die Positionierung korrekt, erfolgt das Absenken des Mantelrohres 2 bis das obere Ende 18 des Futterrohres 3 nach Passieren des Ladungsraumes 19 gegen den das Futterrohr vorderseitig begrenzenden Vorsprung 20 (Fig.1) des Mantelrohres 2 stößt.Subsequently, the casing tube 2 is up to the other end 18 of the casing 3 for checking and possibly correcting the positioning lowered. Is the positioning correct, the jacket tube 2 is lowered until that upper end 18 of the casing 3 after passing through Cargo space 19 against the front of the casing delimiting Projection 20 (Fig.1) of the tubular casing 2 abuts.

Danach wird der für die Erwärmung des mittleren Teilbereiches 21 des Fügebereiches 4 verantwortliche Heizungsteil abgeschaltet und entfernt und dieser Teilbereich dann mit Luft gekühlt. Gleichzeitig kann ein Verschlußstopfen 22 am unteren Ende 23 der Standvorrichtung 6 entfernt werden, damit das noch vorhandene Trockeneis 10 beseitigt werden und sich das Futterrohr nun schneller auf die Temperatur des Mantelrohres erwärmen kann.Then the for the heating of the middle section 21 of the joining area 4 responsible heating part switched off and removed and this part area with air cooled. At the same time, a plug 22 at the bottom End 23 of the stand device 6 are removed so that still existing dry ice 10 can be eliminated and the Casing pipe now faster to the temperature of the casing pipe can heat.

Hat sich das Mantelrohr 2 in dem mittleren Teilbereich 21 um ca. 100°C abgekühlt, so wird die Heizung abgeschaltet und das gesamte Mantelrohr mit Luft abgekühlt. Dieses stufenweise Kühlen be-wirkt, daß das Mantelrohr 2 das Futterrohr 3 zuerst in seinem mittleren Teilbereich 21 festhält und dann von beiden Seiten über das Futterrohr 3 schrumpft. Dadurch wird vermieden, daß durch eine Längskontraktion des Mantelrohres 2 eine Spaltbil-dung am Übergang zwischen dem Futterrohr 3 und dem vorderen Kaliberteil des Mantelrohres 2 auftritt.Has the casing tube 2 in the middle section 21 around cooled about 100 ° C, the heating is switched off and that entire jacket tube cooled with air. This gradually Cooling has the effect that the casing tube 2 and the casing tube 3 come first holds in its central portion 21 and then from both sides shrinks over the casing 3. This will avoided that by a longitudinal contraction of the casing tube 2nd a gap formation at the transition between the casing 3 and the front caliber part of the casing tube 2 occurs.

Ist die Temperatur des Mantelrohres 2 auf ca. 50°C gesunken, kann das Waffenrohr 1 mittels der Hubvorrichtung 14 von der Standvorrichtung 6 gehoben und in die entsprechende Waffe eingebaut werden. If the temperature of the casing tube 2 has dropped to approx. 50 ° C, can the weapon barrel 1 by means of the lifting device 14 of the Stand device 6 raised and in the appropriate weapon to be built in.
