Abstract
Description
Die Erfindung betrifft ein Kraftelement gemäß dem Oberbegriff des Anspruches 1.The invention relates to a force element according to the preamble of claim 1.
Bekannte Kraftelemente funktionieren mit Hilfe eines pyrotechnischen Satzes, der gezündet wird, abbrennt und dabei Gas und andere Komponenten entwickelt, die expandieren und ein Wirk- d. h. Arbeitselement verschieben. Das Arbeitselement ist bspw. als Kolben ausgebildet.Known force elements function by means of a pyrotechnic charge which is ignited, burns off, thereby developing gas and other components which expand and effect. H. Move work item. The working element is, for example, designed as a piston.
Die zur Anwendung gelangenden Bauteile solcher bekannter Kraftelemente sind meist komplexer Natur und üblicherweise drehtechnisch hergestellt. Die Abdichtung zwischen dem Führungselement und dem Arbeitselement ist durch Passungen und/oder durch Dichtungselemente realisiert. Passungen bedingen jedoch einen entsprechenden Herstellungsaufwand. Das wirkt sich auf die Herstellungskosten aus. Durch Dichtungselemente oder durch Ablackieren verschlossene Kraftelemente weisen den Mangel auf, dass sie hinsichtlich möglicher Umweltenflüsse bei der Lagerung nicht hermetisch dicht sind. Ein weiterer Mangel derartiger bekannter Kraftelemente ist ihr relativ großes Bauvolumen. Die verwendeten pyrotechnischen Treibsätze bekannter Kraftelemente weisen relativ große Massen auf und verbrennen unter Bildung von Schlacken und Schmauch, wodurch benachbarte mechanische Komponenten gestört werden können.The components used for such known force elements are usually complex in nature and usually produced by turning technology. The seal between the guide element and the working element is realized by fits and / or by sealing elements. However, fits require a corresponding production cost. This affects the manufacturing costs. Force elements sealed by sealing elements or by means of lacquering have the defect that they are not hermetically sealed with regard to possible environmental flows during storage. Another shortcoming of such known power elements is their relatively large volume of construction. The pyrotechnic propellants of known power elements used have relatively large masses and burn to form slags and smoke, whereby adjacent mechanical components can be disturbed.
In Kenntnis dieser Gegebenheiten liegt der Erfindung die Aufgabe zugrunde, ein Kraftelement der eingangs genannten Art zu schaffen, das einfach und preisgünstig kleinvolumig herstellbar, d. h. miniaturisiert ist ,und die oben genannten Mängel nicht aufweist.In view of these circumstances, the present invention seeks to provide a force element of the type mentioned, which is simple and inexpensive small volume produced, ie miniaturized, and does not have the above-mentioned deficiencies.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst. Bevorzugte Aus- bzw. Weiterbildungen des erfindungsgemäßen miniaturisierten Kraftelementes sind in den Unteransprüchen gekennzeichnet.This object is achieved by the features of claim 1. Preferred embodiments or further developments of the miniaturized force element according to the invention are characterized in the subclaims.
Bei dem erfindungsgemäßen miniaturisierten Kraftelement ist zweckmäßigerweise zumindest das kappenartige Arbeitselement von einem ziehtechnisch hergestellten Blechteil gebildet. Zweckmäßigerweise ist auch das Führungselement für das Arbeitselement von einem ziehtechnisch hergestellten Blechteil gebildet. Von Wichtigkeit ist insbesondere, dass das kappenartig ausgebildete Arbeitselement eine dünne zylindrische Seitenwandung aufweist, so dass das Arbeitselement gegen das zylindrische Führungselement in einfacher Weise zuverlässig abdichtet, indem die dünne Seitenwandung des Arbeitselementes durch den vom Sprengstoff im Ladungsraum generierten Druck expandiert wird und an der Innenseite des Führungselementes abdichtend eng und reibend zur Anlage kommt, so dass eigene Dichtungselemente entbehrlich sind. Durch die besagte Reibung wird in vorteilhafter Weise ein Prellen des Arbeitselementes bei Erreichen der Endposition verhindert.In the case of the miniaturized force element according to the invention, at least the cap-like working element is expediently formed by a sheet-metal part produced by drawing technology. Conveniently, the guide element for the working element is formed by a sheet-metal part produced by drawing. Of particular importance is that the cap-shaped working element has a thin cylindrical side wall, so that the working element reliably seals against the cylindrical guide element in a simple manner by the thin side wall of the working element is expanded by the pressure generated by the explosive in the charge space and on the inside of the guide element sealing tight and rubbing comes to rest, so that own sealing elements are unnecessary. By the said friction bouncing of the working element is prevented upon reaching the end position in an advantageous manner.
Das in vorteilhafter Weise von einem dünnwandigen Blechteil gebildete kappenartige Arbeitselement und das in vorteilhafter Weise ebenfalls von einem Blechteil gebildete Führungselement ermöglichen eine kostengünstige Herstellung und kleine Abmessungen des erfindungsgemäßen Kraftelementes.The advantageously formed by a thin-walled sheet metal part cap-like working element and advantageously also formed by a sheet metal part guide element allow cost-effective production and small dimensions of the force element according to the invention.
Das kappenartige Arbeitselement kann zusätzlich ein weiteres, bspw. drehtechnisch hergestelltes Bauteil, wie eine Anstechnadel o. dgl. aufweisen.The cap-like working element may additionally have another, for example. Rotationally manufactured component, such as a piercing needle o. The like. Have.
Das Führungselement des erfindungsgemäßen miniaturisierten Kraftelementes kann mit einem das Ende des Arbeitsweges des Arbeitselementes bestimmenden Bördelrand ausgebildet sein, so dass am Ende des Arbeitsweges in vorteilhafter Weise keine Teile weggeschleudert werden.The guide element of the miniaturized force element according to the invention may be formed with a beading edge which determines the end of the working path of the working element, so that no parts are advantageously ejected at the end of the working path.
Der einen Sprengstoff enthaltende Ladungsraum des erfindungsgemäßen miniaturisierten Kraftelementes ist im Ruhe- d. h. Lagerzustand hermetisch dicht verschlossen. Das wird dadurch erreicht, dass die Hülse des Abschlusselementes des miniaturisierten Kraftelementes, die dünne zylindrische Seitenwandung des Arbeitselementes und die Zylinderhülse des Führungselementes miteinander abdichtend verschweißt sind. Hierbei kann es sich um eine Laserschweißung handeln.The explosive-containing charge space of the miniaturized force element according to the invention is hermetically sealed in the rest, ie storage condition. This is achieved in that the sleeve of the end element of the miniaturized force element, the thin cylindrical side wall of the working element and the cylinder sleeve of the guide element are sealingly welded together. This can be a laser welding.
Bei der Zündung des im Ladungsraum befindlichen Sprengstoffes reißt der im Ladungsraum erzeugte Druck die in der dünnen Seitenwandung des Arbeitselementes vorgesehene Sollbruchstelle auf, so dass das ursprünglich fixierte Arbeitselement frei wird und sich im Führungselement bis zum Ende seines Arbeitsweges bewegen kann.When the explosive in the charge space is ignited, the pressure generated in the charge space ruptures the predetermined breaking point provided in the thin side wall of the working element, so that the originally fixed working element becomes free and can move in the guide element to the end of its working travel.
Der Ladungsraum kann zur Verringerung des Ladungsvolumens ein Zusatzelement aufweisen. Bei diesem Zusatzelement kann es sich bspw. um ein Inertmaterial handeln.The charge space may have an additional element to reduce the charge volume. This additional element may, for example, be an inert material.
Bei dem erfindungsgemäßen miniaturisierten Kraftelement besteht die Aufladung des Ladungsraumes nicht aus einem pyrotechnischen Satz sondern aus einem Primär- oder Sekundär-Sprengstoff, der bei seiner Umsetzung im Wesentlichen Gas und vernachlässigbar wenig oder keine Metallverbindungen erzeugt. Der Sprengstoff ist in vorteilhafter Weise durch Zusätze und verarbeitungstechnisch so weit phlegmatisiert, dass er unter den gegebenen Bedingungen nicht detoniert sondern lediglich abbrennt. Auf diese Weise wird eine hinreichend stoßwellenarme Beschleunigung des kappenartigen Arbeitselementes im Führungselement erreicht.In the miniaturized force element according to the invention, the charging of the charge space does not consist of a pyrotechnic charge but of a primary or secondary explosive, which generates substantially gas and negligible or no metal compounds during its conversion. The explosive is advantageously phlegmatized by additives and processing technology so far that it does not detonate under the given conditions but merely burns off. In this way, a sufficiently shock-wave acceleration of the cap-like working element is achieved in the guide element.
Die Minimierung der Aufladung erlaubt in vorteilhafter Weise außerdem eine Erhöhung der Sicherheit des erfindungsgemäßen Kraftelementes.The minimization of the charge also advantageously allows an increase in the safety of the force element according to the invention.
Weitere Einzelheiten, Merkmale und Vorteile ergeben sich aus der nachfolgenden Beschreibung eines in der Zeichnung vergrößert dargestellten Ausführungsbeispiels des erfindungsgemäßen miniaturisierten Kraftelementes.Further details, features and advantages will become apparent from the following description of an enlarged embodiment of the inventive miniaturized force element shown in the drawing.
