Abstract
Description
Die Neuerung betrifft eine Vorrichtung zum Gießen eines kunststoffgebundenen Sprengstoffs in ein Hohlprofil, dessen Querschnittsmaß um ein Vielfaches kleiner ist als dessen Länge.The Innovation relates to a device for casting a plastic-bound Explosives in a hollow profile whose cross-sectional dimension to a Many times smaller than its length.
Üblicherweise werden kunststoffgebundene Sprengstoffe zur Herstellung von gegossenen Ladungen, insbesondere von Gefechtsköpfen verwendet. Diese Ladungen sind in der Regel dadurch charakterisiert, dass die Quer- und Längsabmessungen sich um kaum mehr als den Faktor Zwei unterscheiden.Usually are plastic-bonded explosives for the production of cast Cargoes, especially used by warheads. These charges are usually characterized by the fact that the transverse and longitudinal dimensions are to differ by no more than a factor of two.
Es sind aber auch besondere Bauformen von Ladungen bekannt geworden, die sich von den üblichen Ladungen dadurch unterscheiden, dass sie um ein Vielfaches länger als ihre Querabmessung sind. Ein Beispiel hierfür ist in der DE-OS 25 23 447 beschrieben. Bei dieser Ladung ist der kunststoffgebundene Sprengstoff in einem Metallprofilteil mit etwa U-förmigem Querschnitt angeordnet, wobei das Querschnittsmaß des Metallprofilteils um ein Vielfaches kleiner ist als dessen Längsabmessung.It but also special designs of cargoes have become known which is different from the usual Charges differ in that they are many times longer than their transverse dimensions are. An example of this is in DE-OS 25 23 447 described. This charge is the plastic-bound explosive arranged in a metal profile part with an approximately U-shaped cross-section, the cross sectional dimension of Metal profile part is smaller by a multiple than its longitudinal dimension.
Es ist in dieser Druckschrift jedoch kein Hinweis darauf gegeben, in welcher Weise ein gießfähiger Sprengstoff mit teigig-zäher Konsistenz in das schmale Profil ohne Erzeugung von Luftblasen oder anderen Fehlstellen eingebracht werden soll. Noch schwieriger als das Befüllen eines U-förmigen Profils ist das Einbringen von derartigem Sprengstoff in ein geschlossenes Profil mit etwa O-förmigem Querschnitt. Ein derartiges Metallprofil ist in der DE-OS 22 54 879 dargestellt und beschrieben. Auch hier fehlt jegliche Angabe, wie die zähflüssige Gießmasse des Sprengstoffes in ein langes Stück eines derartigen Profils eingebracht werden soll.It However, in this document no indication is given in which way a pourable explosive with doughy-tougher Consistency in the narrow profile without generating air bubbles or others Defects should be introduced. Even more difficult than filling one U-shaped Profils is the introduction of such explosives in a closed Profile with approximately O-shaped cross-section. Such a metal profile is shown in DE-OS 22 54 879 and described. Here, too, lacks any information, such as the viscous casting compound of the explosive in a long piece such a profile is to be introduced.
Es ist Aufgabe der vorliegenden Neuerung, eine Vorrichtung anzugeben, mit deren Hilfe kunststoffgebundener Sprengstoff in der gießfähigen Phase luftblasenfrei in ein geschlossenes Hohlprofil eingebracht werden kann, dessen Querschnittsmaß um ein Vielfaches kleiner ist als dessen Länge.It The object of the present invention is to specify a device with their help plastic bound explosive in the pourable phase be introduced bubble-free in a closed hollow profile can, whose cross-sectional dimension to one Many times smaller than its length.
Die neuerungsgemäße Vorrichtung umfasst eine evakuierbare trichterförmige Gießkammer welche über einen Ansatz mit dem ersten Ende des Hohlprofils abdichtend verbindbar ist und eine unabhängig von der Gießkammer evakuierbare geschlossene Kammer, welche mit dem weiteren Ende des Hohlprofils abdichtend verbindbar ist. Damit ist sichergestellt, dass der Gießvorgang unter Vakuum stattfinden kann, wobei die Beaufschlagung mit Vakuum oder die Belüftung auf beiden Seiten des zu befüllenden Hohlprofils unabhängig voneinander durchgeführt werden kann.The device according to the invention comprises an evacuable funnel-shaped casting chamber which via a Approach sealingly connectable to the first end of the hollow profile is and an independent from the casting room evacuable closed chamber, which with the other end of the hollow profile is sealingly connectable. This ensures that the casting process can take place under vacuum, the application of vacuum or the ventilation on both sides of the to be filled Hollow profiles independent performed from each other can be.
In vorteilhafter Weise ist im Bereich des Übergangs vom weiteren Ende des Hohlprofils zur evakuierbaren geschlossenen Kammer ein gasdurchlässiger und für die Sprengstoffgießmasse undurchlässiger Filter angeordnet. Dieser Filter begrenzt während des Gießens das Sprengstoffvolumen in Flussrichtung der Gießmasse und ermöglicht gleichzeitig die durch das Vakuum in der geschlossenen Kammer erzeugte saugende Wirkung auf die Gießmasse im Hohlprofil.In Advantageously, in the area of the transition from the other end the hollow profile for evacuated closed chamber a gas permeable and for the Sprengstoffgießmasse impermeable Filter arranged. This filter limits this during casting Explosive volume in the flow direction of the casting compound and allows simultaneous the sucking generated by the vacuum in the closed chamber Effect on the casting material in the hollow profile.
Gut geeignet ist hierbei ein Filter, der aus einem offenporigen gesinterten Metallpulver oder aus einem offenporigen Keramikwerkstoff besteht. Somit wird mittels eines dünnen plattenförmigen Filters ein gasdurchlässiger Abschluss des Hohlprofils gebildet, der eine ausreichende Stabilität aufweist.Well suitable here is a filter made of an open-pored sintered Metal powder or consists of an open-pored ceramic material. Thus, by means of a thin disc-shaped Filters a gas permeable Formed completion of the hollow profile, which has sufficient stability.
Zusätzlich wird der Filter sprengstoffseitig mit einer gasdurchlässigen Folie bedeckt. Besonders gut geeignet ist eine Folie aus einer mikroporösen Kunststoffmembran. Diese ist im gewünschten Maß gasdurchlässig und dient gleichzeitig dazu, an der dem Sprengstoff zugewandten Trennfläche während des Aushärtungsvorganges beim Sprengstoff eine Oberfläche hoher Güte auszubilden.In addition will the filter on the explosive side covered with a gas-permeable film. Especially Well suited is a film of a microporous plastic membrane. These is in the desired Dimension permeable to gas and At the same time, it serves to stop the explosive-facing interface during the curing process at the explosive a surface high quality train.

Mit Hilfe dieser beschriebenen Vorrichtung ist es möglich, sehr schlanke Hohlprofile mit hoher Qualität herzustellen. Insbesondere zeichnen sich die gegossenen Sprengstoffprofile durch das Fehlen von Luftblasen aus. Weiterhin wird eine hohe Güte der Außenflächen der fertigen Sprengstoffmasse erreicht.With Help this described device, it is possible very slim hollow sections with high quality manufacture. In particular, the cast explosive profiles are distinguished due to the absence of air bubbles. Furthermore, a high quality of the outer surfaces of the finished explosive mass reached.
