Description

Die Erfindung betrifft eine Vorrichtung zur Befestigung einer Patronenhülse an einem Geschoss, insbesondere Unterkalibergeschoss, wobei an einem Treibspiegel mindestens eine Umfangsnut vorgesehen ist und die Patronenhülse durch Kerbung an der Umfangsnut mit dem Treibspiegel des Geschosses verbindbar ist.The invention relates to a device for fastening a cartridge case to a projectile, in particular a sub-caliber projectile, wherein at least one circumferential groove is provided on a sabot and the cartridge case can be connected to the sabot of the projectile by notching on the circumferential groove.

Bei Unterkalibergeschossen, auch Treibspiegelgeschosse genannt, ist der eigentliche Geschosskörper von einem sogenannten Treibspiegel ummantelt, der kurz nach dem Abschuss abgeworfen wird. Ein beispielsweise mit der europäischen Patentanmeldung 0 624 774 bekannt gewordener Treibspiegel für ein flügelstabilisiertes Unterkalibergeschoss setzt sich aus einem Treibspiegelkörper und einem Treibspiegelmantel zusammen. Zum Zwecke der auch Patronierung genannten Befestigung der Patronenhülse ist am Treibspiegelkörper eine Umfangsnut vorge-sehen, wobei die Patronenhülse an dieser Stelle durch Kerbung mit dem das Geschoss tragenden Treibspiegel verbunden werden kann. Eine solche Verbindung muss dicht sein, so dass sich bei der Zündung der erforderliche hohe Explo-sionsdruck aufbauen kann und das Pulver in der Patronenhülse gegen das Eindringen von Flüssigkeiten geschützt ist.In the case of sub-caliber bullets, also known as sabot projectiles, the actual projectile body is encased by a so-called sabot that is thrown off shortly after the shot. A sabot for a wing-stabilized lower-caliber projectile, which has become known, for example, with the European patent application 0 624 774 , is composed of a sabot body and a sabot jacket. For the purpose of fastening the cartridge case, also called cartridge, a circumferential groove is provided on the sabot body, wherein the cartridge case can be connected at this point by notching to the sabot carrying the projectile. Such a connection must be tight, so that the required high explosion pressure can build up during ignition and the powder in the cartridge case is protected against the ingress of liquids.

Bei konventionellen Methoden zur Kerbung von insbesondere aus Stahlblech bestehenden Patronenhülsen werden wegen der relativ grossen erforderlichen Kräfte Vorrichtungen mit radial bewegbaren Segmenten verwendet. Hierbei können jedoch undichte Stellen entstehen, so dass die vorstehend beschriebenen Anforderungen, die an eine solche Verbindung gestellt werden, nur mit einem zusätzlichen Dichtmittel erfüllt werden können.In conventional methods for notching cartridge cases consisting in particular of sheet steel, devices with radially movable segments are used because of the relatively large forces required. Leakages can occur here, however, so that the requirements described above that are placed on such a connection can only be met with an additional sealant.

Der Erfindung liegt daher die Aufgabe zugrunde eine Vorrichtung der eingangs genannten Art vorzuschlagen, mittels welcher unter Vermeidung der vorstehend erwähnten Nachteile eine dichte Verbindung zwischen aus Stahlblech bestehenden Patronenhülsen und Geschossen herstellbar ist.The invention is therefore based on the object of proposing a device of the type mentioned by means of which a tight connection between cartridge cases made of sheet steel and projectiles can be produced while avoiding the disadvantages mentioned above.

Diese Aufgabe wird durch die im Patentanspruch 1 angegebene Erfindung gelöst. Hierbei ist ein Druckstück für die Aufnahme des Geschosses vorgesehen, das einen zylindrischen Ansatz aufweist, der in eine Bohrung einer Matrize hineinragt. In der Bohrung, im Bereich der Umfangsnut und eines Hülsenmundes der Patronenhülse ist ein elastischer Ring angeordnet, dessen eine Stirnfläche dem zylindrischen Ansatz des Druckstückes zugewandt ist, und dessen andere Stirnfläche über eine Dichtscheibe an zwei senkrecht zur Längsachse der Patrone in der Matrize geführten Schieber anliegt. Bei der Kerbung wird die Matrize mit den Schiebern gegen das Druckstück geschoben, wobei der elastische Ring über die Dichtscheibe zusammengedrückt und in radialer Richtung nach innen verformt wird, so dass der Hülsenmund in die Umfangsnut gedrückt wird.This object is achieved by the invention specified in claim 1 . Here, a pressure piece is provided for receiving the projectile, which has a cylindrical extension which projects into a bore in a die. In the bore, in the area of the circumferential groove and a sleeve mouth of the cartridge case, an elastic ring is arranged, one end face of which faces the cylindrical extension of the pressure piece, and the other end face of which, via a sealing washer, bears against two slides guided perpendicular to the longitudinal axis of the cartridge in the die . During the notching, the die is pushed against the pressure piece with the slides, the elastic ring being pressed together via the sealing disk and being deformed inward in the radial direction, so that the sleeve mouth is pressed into the circumferential groove.

Gemäss einer besonderen Ausführung besteht der elastische Ring aus Vulkolan vom Typ Adipren. Die Dichtscheibe besteht beispielsweise aus gehärtetem Federstahl von 0,3 mm Dicke, wobei die dem elastischen Ring zugewandte Kante des Innendurchmessers der Dichtscheibe abgerundet ist.According to a special design, the elastic ring is made of Vulkolan type Adipren. The sealing washer is made, for example, of hardened spring steel 0.3 mm thick, the edge of the inner diameter of the sealing washer facing the elastic ring being rounded.

Die mit der Erfindung erzielten Vorteile sind darin zu sehen, dass gleichmässige, dichte Verbindungen zwischen aus Stahlblech bestehenden Patronenhülsen und Geschossen bei hoher Standzeit des elastischen Ringes herstellbar sind. Das wird insbesondere durch die Anwendung der vorgeschlagenen Dichtscheibe und deren Gestaltung erreicht. Die Dichtscheibe schützt den elastischen Ring vor der Bewegung der Schieber, wobei die Abnutzung des elastischen Ringes bei der kleinen Bewegung zu den Schiebern hin wegen geringen Dicke der Dichtscheibe und der abgerundeten Kante sehr gering ist. Wie Versuche bestätigen, können daher trotz der hohen auftretenden Kräfte mindestens 5000 Patronierungszyklen erreicht werden, ohne dass ein nennenswerter Abrieb des elastischen Ringes feststellbar ist.The advantages achieved by the invention can be seen in the fact that uniform, tight connections between cartridge cases made of sheet steel and projectiles can be produced with a long service life of the elastic ring. This is achieved in particular through the use of the proposed sealing washer and its design. The sealing washer protects the elastic ring from the movement of the slide, the wear of the elastic ring during the small movement towards the slide being very small due to the small thickness of the sealing washer and the rounded edge. As tests confirm, can therefore of the high forces occurring, at least 5000 patronizing cycles can be achieved without any noticeable abrasion of the elastic ring being detectable.

Weitere Vorteile liegen darin, dass aufgrund der hohen Standzeit teure Werkzeugwechselkosten entfallen. Der sehr geringe Abrieb bewirkt weiterhin, dass der Ausziehwiderstand die Funktion der Patrone nicht beeinträchtigen kann.Further advantages are that expensive tool change costs are eliminated due to the long service life. The very low abrasion also means that the pull-out resistance cannot impair the function of the cartridge.

In den Fig. 1 bis 3 ist mit 1 eine Aufnahmebüchse bezeichnet, in welcher ein Druckstück 2 angeordnet ist, das durch einen Sicherungsring 3 in der Aufnahmebüchse 1 gehalten wird. Das Druckstück 2 weist einen zylindrischen Ansatz 4 auf, der in eine Bohrung 5 einer ebenfalls in der Aufnahmebüchse 1 angeordneten Matrize 6 hineinragt. Das Druckstück 2 nimmt während der nachstehend näher beschriebenen Patronierung das Geschoss einer Patrone 7 auf, wobei die Geschossspitze 8 in einer Zentrierung 9 geführt, und ein konischer Teil der Patronenhülse 10 in der Matrize 6 aufgenommen wird. In der Bohrung 5, im Bereich eines Hülsenmundes 11 der Patronenhülse 10 und einer an einem Treibspiegel 12 des Geschosses vorgesehenen Umfangsnut 13, ist ein elastischer Ring 14 angeordnet, der beispielsweise aus Vulkolan vom Typ Adipren besteht. Der Aussendurchmesser des elastischen Ringes 14 entspricht dem Durchmesser der Bohrung 5, während sein Innendurchmesser grösser als der Durchmesser des Hülsenmundes 11 bzw. des Geschosses ist. Die eine Stirnfläche des elastischen Ringes 14 ist der Stirnfläche des zylindrischen Ansatzes 4 zugewandt, während die andere Stirnfläche über eine Dichtscheibe 15 an zwei Schiebern 16 anliegt. Die Schieber 16 werden senkrecht zur Längsachse 17 der Patrone 7 in der Matrize 6 geführt und können mittels an Halterungen 18.1 befestigten, beispielsweise pneumatisch betätigbaren doppeltwirkenden Zylindern 18 verschoben werden. Die Dichtscheibe 15 besteht vorzugsweise aus gehärtetem Federstahl von 0,3 mm Dicke. Der Aussendurchmesser der Dichtscheibe 15 entspricht dem Durchmesser der Bohrung 5, während sein Innendurchmesser um ein geringes Spiel grösser als der Durchmesser des Hülsenmundes 11 bzw. des Geschosses ist. 1 to 3 , 1 denotes a receptacle in which a pressure piece 2 is arranged, which is held in the receptacle 1 by a locking ring 3 . The pressure piece 2 has a cylindrical projection 4 which projects into a bore 5 of a die 6 which is also arranged in the receiving bushing 1. The pressure piece 2 receives the bullet of a cartridge 7 during the cartridge described in more detail below, the bullet tip 8 being guided in a centering 9 and a conical part of the cartridge case 10 being received in the die 6 . In the bore 5 , in the area of a sleeve mouth 11 of the cartridge case 10 and a circumferential groove 13 provided on a sabot 12 of the projectile, an elastic ring 14 is arranged, which consists, for example, of Vulkolan of the Adipren type. The outer diameter of the elastic ring 14 corresponds to the diameter of the bore 5 , while its inner diameter is larger than the diameter of the sleeve mouth 11 or the projectile. One end face of the elastic ring 14 faces the end face of the cylindrical extension 4 , while the other end face rests against two slides 16 via a sealing washer 15 . The slides 16 are guided perpendicular to the longitudinal axis 17 of the cartridge 7 in the die 6 and can be moved by means of double-acting cylinders 18 fastened to brackets 18.1 , for example pneumatically operated. The Sealing disc 15 is preferably made of hardened spring steel 0.3 mm thick. The outer diameter of the sealing disk 15 corresponds to the diameter of the bore 5 , while its inner diameter is a little more than the diameter of the sleeve mouth 11 or the projectile.

Die dem elastischen Ring 14 zugewandte Kante 19 des Innendurchmessers der Dichtscheibe 15 ist abgerundet (Fig. 2 und 3). In der Aufnahmebüchse 1 ist eine Druckfeder 20 angeordnet, die einerseits an einer Schulter 21 des Druckstückes 2 und andererseits an einer Schulter 22 der Matrize 6 anliegt. Die Patrone 7 wird an ihrem hinteren Ende auf einem in der Längsachse 17 der Patrone 7 bewegbaren Untersatz 23 durch einen federnden Einsatz 24 und einem Halter 25 festgehalten.The edge 19 of the inner diameter of the sealing disk 15 facing the elastic ring 14 is rounded ( FIGS. 2 and 3 ). A compression spring 20 is arranged in the receiving bushing 1 , which rests on the one hand on a shoulder 21 of the pressure piece 2 and on the other hand on a shoulder 22 of the die 6 . The cartridge 7 is held at its rear end on a base 23 movable in the longitudinal axis 17 of the cartridge 7 by a resilient insert 24 and a holder 25 .

Die vorstehend beschriebene Vorrichtung arbeitet wie folgt:The device described above works as follows:

Mittels eines beispielsweise hydraulisch betätigbaren nicht weiter dargestellten Einstosszylinders wird der Untersatz 23 mit der Patrone 7 hochgefahren und das Geschoss durch die Matrize 6 in das Druckstück 2 eingeschoben. Sodann werden die Schieber 16 durch die beiden Zylinder 18 nach innen geschoben, bis sie an der Patronenhülse 10 anliegen. Hierbei wird der durch das Spiel zwischen Dichtscheibe 15 und Patronenhülse 10 gegebene Spalt von den Schiebern 16 überbrückt (Fig. 2 und 3). Danach wird die Aufnahmebüchse 1 und mit ihr die Matrize 6 mit den Schiebern 16 mittels eines ebenfalls z.B. hydraulisch betätigbaren, nicht weiter dargestellten Kerbzylinders gegen das feststehende Druckstück 2 und die Druckfeder 20 hochgefahren und der elastische Ring 14 über die Dichtscheibe 15 zusammengedrückt. Hierbei wird der elastische Ring 14 in radialer Richtung nach innen verformt und der Hülsenmund 11 in die Umfangsnut 13 des Treibspiegels 12 gedrückt (Fig. 3). Bei diesem Vorgang schützt die Dichtscheibe 15 den elastischen Ring 14 vor der Bewegung der Schieber 16, wobei die Abnutzung des elastischen Ringes 14 bei der kleinen Bewegung zu den Schiebern 16 hin wegen der abgerundeten Kante 19 der Dichtscheibe 15 sehr gering ist. Nach der Kerbung werden der Kerbzylinder und danach die beiden Zylinder 18 wieder zurückgefahren, so dass die Aufnahmebüchse 1, die Matrize 6 und die beiden Schieber 16 wieder die Ausgangsposition einnehmen. Anschliessend fährt der Einstosszylinder zurück, so dass die gekerbte Patrone 7 vom Untersatz 23 abgenommen und eine neue aufgesetzt werden kann.By means of a push-in cylinder, not shown, for example, which can be operated hydraulically, the base 23 with the cartridge 7 is raised and the projectile is pushed through the die 6 into the pressure piece 2 . The slides 16 are then pushed inwards by the two cylinders 18 until they abut the cartridge case 10 . Here, the gap given by the play between the sealing disk 15 and the cartridge case 10 is bridged by the slides 16 ( FIGS. 2 and 3 ). Then the receiving bushing 1 and with it the die 6 with the slides 16 are raised by means of a notch cylinder, which is also, for example, hydraulically actuated, not further shown, against the fixed pressure piece 2 and the compression spring 20 and the elastic ring 14 is pressed together via the sealing disk 15 . Here, the elastic ring 14 is deformed radially inwards and the sleeve mouth 11 is pressed into the circumferential groove 13 of the sabot 12 ( FIG. 3 ). In this process, the sealing disk 15 protects the elastic ring 14 from the movement of the slider 16 , the wear of the elastic ring 14 during the small movement towards the slider 16 being very low because of the rounded edge 19 of the sealing disk 15 . After the notching, the notch cylinder and then the two cylinders 18 are moved back again, so that the receiving bushing 1 , the die 6 and the two slides 16 assume the starting position again. The push-in cylinder then moves back so that the notched cartridge 7 can be removed from the base 23 and a new one can be put on.
