Abstract
Description
Die Erfindung bezieht sich auf eine Führungsbandbefe stigung an einem Geschoß entsprechend den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a guide belt attachment on a floor according to the characteristics of the The preamble of claim 1.
Aus der EP 03 04 506 A1 ist ein Verfahren zum Aufbringen und Befestigen von Führungsbändern auf Geschoßhüllen be kannt, bei dem das Führungsband in zentripetaler Richtung auf eine Geschoßhülle über ein Laserstrahl- bzw. Elek tronenstrahl-Schweißverfahren unter radialer Einstrahlung geschweißt ist. Dieses Verfahren eignet sich für dünne Ge schoßhüllen, bei denen üblicherweise eine Nut für das Führungsband nicht vorgesehen werden kann.EP 03 04 506 A1 describes a method for application and attaching guide tapes to projectile casings knows, in which the guide band in the centripetal direction on a bullet shell via a laser beam or elec Trone beam welding process under radial irradiation is welded. This method is suitable for thin Ge lap sleeves, which usually have a groove for the Guide band can not be provided.
Als Werkstoff für das Führungsband wird Weicheisen einge setzt, das jedoch den Verschleiß des Waffenrohres sehr stark erhöht.Soft iron is used as the material for the guide belt sets, however, the wear of the gun barrel very much greatly increased.
Versuche, rohrschonendere Werkstoffe, wie Kupferlegierun gen mit dem genannten Verfahren aufzuschweißen, scheiter ten bisher.Attempts to use more pipe-friendly materials, such as copper alloy welding on with the above-mentioned process, failed so far.
Aufgabe der Erfindung ist es, für ein aus einer Kupferle gierung bestehendes Führungsband eine sichere und kosten günstige Befestigungsart vorzuschlagen.The object of the invention is for a copper existing guiding tape a safe and cost to propose a favorable type of fastening.
Die Erfindung löst diese Aufgabe entsprechend den kenn zeichnenden Merkmalen des Anspruches 1.The invention solves this problem in accordance with the characterizing features of claim 1.
Eine vorteilhafte Weiterbildung der Erfindung ist dem Un teranspruch zu entnehmen.An advantageous development of the invention is the Un claim.
Gemäß der Erfindung liegt bei axialer Einstrahlung in die Nahtstelle von Führungsband und Geschoßhülle eine halt bare, vollflächig verschweißte Verbindung durch das Laser- bzw. Elektronenstrahlschweißverfahren vor.According to the invention lies in the case of axial irradiation A stop between the guide band and the shell Bare, fully welded connection through the laser or Electron beam welding process.
Besonders eignet sich diese Befestigungsart für dünne Ge schoßhüllen.This type of fastening is particularly suitable for thin Ge lap covers.
Die Schweiß-Verbindung entsteht sowohl durch eine soge nannte Legierung des Führungsband-Werkstoffes mit dem Stahlwerkstoff der Geschoßhülle aufgrund des Nickelan teiles als auch durch mechanische Verkrallung des Grund werkstoffes, nämlich Stahl, mit dem Führungsbandwerkstoff, nämlich Kupferanteile, infolge Durchmischung.The weld connection is created by a so-called called alloy of the guide band material with the Steel material of the shell due to the nickel part as well as by mechanical clawing of the bottom material, namely steel, with the guide belt material, namely copper components, due to mixing.
Die Verkrallung von Führungsband und Geschoßhülle wird nach dem Anspruch 2 dadurch gefördert, daß die Befesti gungsflächen von Führungsband und Geschoßhülle mit Form schlußmitteln, wie Gewinde oder auch Stegen, versehen sind.The claw of the guide band and the shell of the projectile will promoted according to claim 2 in that the fastener surfaces of the guide band and the shell with shape closing means, such as threads or webs are.
Ein Ausführungsbeispiel ist in der Zeichnung dargestellt. Es zeigt An embodiment is shown in the drawing. It shows
Fig. 1 einen Abschnitt einer Geschoßhülle im Längs schnitt und Fig. 1 shows a section of a shell in longitudinal section and
Fig. 2 den Abschnitt nach Fig. 1 in einer anderen Ausführung. Fig. 2 shows the section of FIG. 1 in another embodiment.
Eine dünne Geschoßhülle 1 aus Stahl weist heckseitig ein Führungsband 2 aus einer Kupfer-Nickel-Legierung, nämlich CuNi5 auf. Das Führungsband 2 ist über eine Schweißzone 3 mit der Geschoßhülle 1 fest verbunden und weist eine Breite 7 auf.A thin projectile casing 1 made of steel has a guide band 2 made of a copper-nickel alloy, namely CuNi5, on the rear side. The guide belt 2 is fixedly connected via a weld zone 3 with the projectile casing 1 and has a width of 7.
Die Schweißzone 3 wird durch die axiale Einstrahlung 4 durch einen Elektronenstrahl eines nicht dargestellten Elektronenstrahlschweißgerätes erzeugt. Die Schweißzone 3 erstreckt sich in dem Führungsband 2 über die gesamte Breite des Führungsbandes 2 und über einen entsprechenden Bereich 6 der Geschoßhülle 1. Damit liegt eine vollflächig verschweißte Verbindung an der ringförmigen Nahtstelle 5 vor.The welding zone 3 is generated by the axial irradiation 4 by an electron beam from an electron beam welding device, not shown. The welding zone 3 extends in the guide band 2 over the entire width of the guide band 2 and over a corresponding area 6 of the projectile casing 1 . A connection welded over the entire surface is thus present at the annular interface 5 .
Nach Fig. 2 weist die Geschoßhülle 1 und auch das Füh rungsband 2 ein mehrgängiges Steilgewinde 10, 11 auf. Damit wird die Verkrallung des Stahlwerkstoffes der Ge schoßhülle 1 mit dem Werkstoff des Führungsbandes 2 ver bessert. Ein weiterer Vorteil besteht in der leichten Mon tage des Führungsbandes 2 durch Aufschrauben auf die Ge schoßhülle 1.According to FIG. 2, the projectile casing 1 and also the Füh approximately tape 2, a multi-start coarse thread 10, 11. So that the claw of the steel material of the Ge shell 1 is improved with the material of the guide band 2 ver. Another advantage is the easy assembly of the guide belt 2 by screwing it onto the lap cover 1 .
Neben dem mehrgängigen Steilgewinde 10, 11 sind zur Ver krallung der oben beschriebenen Werkstoffe auch andere Formmittel möglich, wie einfache ineinandergreifende radiale Stege.In addition to the multi-start high-helix thread 10 , 11 , other shaping means are also possible for clawing the materials described above, such as simple interlocking radial webs.
