Abstract
A device for measuring gas pressure inside cartridges has an essentially cylindrical housing (10) mounted on a base plate (13) and provided with a stepped bore (12a, 12b) in the axial direction that tapers in the direction of the shot and into which a correspondingly outwardly stepped measurement barrel (11) that receives the cartridge (15, 16) can be adapted. An enlarged bore with an inner thread (25a) is provided in the rear region of the housing (10), and a threaded closure body (25b) can be screwed therein. A striking pin that is axially movable in the direction of the shot is arranged inside the closure body (25b). Furthermore, a clamping device (23, 23a) engages a headpiece (26) by its rear part and when it is activated, it first pulls the headpiece partially out, then liberates it, by continuing to move, thus triggering the striking pin. An upsetting body arranged in a radial bore (30) of the measurement barrel (11) can be upset by a measurement piston (19) moved by the gas pressure during the shot. The advantage of the invention is its simple design, made up of few rotary pieces, so that its cost effective production is possible.

"Vorrichtung zum Messen des Gasdrucks von Patronen""Device for measuring the gas pressure of cartridges"
Aus dem Stand der Technik sind Vorrichtungen zum Messen des Gasdrucks von Patronen bekannt, die für den gewerblich¬ industriellen Gebrauch, also beispielsweise für Patronenhersteller, konzipiert sind, entsprechend groß dimensioniert sind, konstruktiv aufwendig sind und folglich zu einem vergleichsweise hohen Preis auf dem Markt angeboten werden.Devices for measuring the gas pressure of cartridges are known from the prior art, which are designed for commercial-industrial use, that is to say for cartridge manufacturers, for example, are of correspondingly large dimensions, are structurally complex and are consequently offered on the market at a comparatively high price become.
Bei zahlreichen Privatpersonen wie z. B. Jägern und Sportschützen hat es. sich eingebürgert, daß diese die Patronen für ihren eigenen Bedarf selbst nach Gebrauchsanweisung des Herstellers der Zündmischung von Hand laden. Dies ist mit einem relativ hohen Gefahrenrisiko verbunden, da nicht auszuschließen ist, daß bei diesem Laden von Hand eine zu hohe Menge der Treibladung verwendet wird, was im ungünstigsten Fall sogar die Zerstörung einer Waffe beim Abschuß dieser selbstgeladenen Patronen zur Folge haben kann.With numerous private individuals such as B. Hunters and marksmen have it. it is common practice for them to load the cartridges by hand for their own needs, even according to the instructions for use provided by the manufacturer of the ignition mixture. This is associated with a relatively high risk of danger, since it cannot be ruled out that an excessive amount of propellant charge is used in this manual loading, which in the worst case can even result in the destruction of a weapon when these self-loading cartridges are fired.
Die Aufgabe der vorliegenden Erfindung ist folglich, eine Vorrichtung zum Messen des Gasdrucks von Patronen zu schaffen, die für den privaten Gebrauch geeignet ist und dem "Handlader" eine einfache Überprüfung der selbstgeladenen Patronen ermöglicht und gleichzeitig mit vertretbarem Kostenaufwand erworben werden kann.The object of the present invention is therefore to provide a device for measuring the gas pressure of cartridges, which is suitable for private use and enables the "hand loader" to easily check the self-loading cartridges and at the same time can be purchased at a reasonable cost.

Die erfindungsgemäße Vorrichtung zur Messung des Gasdruckes von Patronen weist einen im wesentlichen zylindrischen an Oberseite und Unterseite abgeflachten Gehäusekörper 10 aus hochfestem Duraluminium auf, der auf einer Grundplatte 13 angeordnet ist. In axialer Richtung weist dieser Gehäusekörper 10 eine sich in Schußrichtung stufenförmig verjüngende Stufenbohrung 12b, 12a auf, in die ein Meßlauf ιι, der entsprechend stufenförmig geformt ist, in axialer Richtung einschiebbar ist. In die Laufbohrung 14 des Meßlaufs 11 wird die Patrone 16 mit Geschoß 15 und Treibladung 17 eingebracht. Bei eingeschobenem Meßlauf 11 schließt sich an diesen in axialer Richtung in dem Gehäusekörper 10 zur Rückseite hin eine Bohrung mitThe device according to the invention for measuring the gas pressure of cartridges has an essentially cylindrical housing body 10 made of high-strength duralumin, which is flattened at the top and bottom and which is arranged on a base plate 13. In the axial direction, this housing body 10 has a stepped bore 12b, 12a tapering in the weft direction, into which a measuring run ιι, which is correspondingly stepped, can be inserted in the axial direction. The cartridge 16 with the projectile 15 and propellant charge 17 is introduced into the bore 14 of the measuring barrel 11. When the measuring barrel 11 is pushed in, a bore closes in the axial direction in the housing body 10 towards the rear
Innengewinde 25a an, deren Nenndurchmesser um einiges größer ausgelegt ist und beispielsweise um etwa 50 % größer ist, als der Durchmesser 12b der Meßlaufwurzel. Bei eingeschobenem Meßlauf 11 bleibt zunächst der hintere Bereich mit der Gewindebohrung 25a mit erweitertemInternal thread 25a, the nominal diameter of which is designed to be somewhat larger and, for example, is approximately 50% larger than the diameter 12b of the measuring barrel root. When the measuring run 11 is inserted, the rear area with the threaded bore 25a initially remains with an enlarged area
Durchmesser frei. Dieser Bereich der Gewindebohrung 25a sollte sich in etwa über 25 % der axialen Länge des gesamten Gehäusekörpers 10 erstrecken.
In die rückwärtige Gewindebohrung 25a des Gehäusekörpers 10 ist ein Gewinde eines vergleichsweise einfach ausgebildeten Verschlußkörpers 25 einschraubbar. Dieser Verschlußkörper ist vorzugsweise ebenfalls aus Duraluminium F 52 gefertigt und weist einen innenliegenden Schlagbolzen als Zündeinrichtung auf, der in axialer Richtung beweglich ist und der auf die in die Laufbohrung 14 eingeschobene Patrone 16 aufschlägt. Das Verschlußstück 25, ein rotatiόnssymmetrischer länglicher Hohlkörper ist als reines Drehteil günstig zu fertigen. Der vordere Gewindeabschnitt 25a des Verschlußstücks setzt sich nach hinten in einem zylindrischen Abschnitt 25b mit reduziertem Außendurchmesser fort. An diesem zylindrischen Abschnitt 25b liegt endseitig ein gegenüber dem Verschlußstück im Durchmesser zunächst etwas reduziertes Kopfstück 26 an, das jedoch in seinem hinteren Bereich eine konische Verdickung 28 aufweist, an die sich wiederum ein zylindrischer im Durchmesser größerer Abschnitt 27 des Kopfstücks anschließt. Auf diese Weise ergibt sich zwischen der konischen Verdickung 28 des Kopfstücks und dem zylindrischen Bereich 25 des Verschlußstücks im Bereich des reduzierten Durchmessers 26 des Kopfstücks eine Art Nut. Das Kopfstück 26 ist mit dem innen im Verschlußstück 25 liegenden Schlagbolzen 33 fest verbunden. Zum Spannen des Schlagbolzens durch Herausziehen des Kopfstücks kann der Spannhebel 23 in Pfeilrichtung umgelegt werden, wobei der untere etwa U-förmig gebogene Spannbügel 23a des Spannhebels über die Schrägfläche der konischen Erweiterung 28 rutscht, zunächst das Kopfstück 26 um einige Millimeter herauszieht und dann schließlich das Ende des Kopfstücks 27 freigibt, so daß der Schlagbolzen durch die Federkraft auf die Patrone 16 aufschlägt und die Treibladung 17 zündet.Diameter free. This area of the threaded bore 25 a should extend approximately over 25% of the axial length of the entire housing body 10. A thread of a comparatively simple closure body 25 can be screwed into the rear threaded bore 25a of the housing body 10. This closure body is preferably also made of duralumin F 52 and has an internal firing pin as an ignition device, which is movable in the axial direction and which strikes the cartridge 16 inserted into the barrel bore 14. The closure piece 25, a rotationally symmetrical, elongated hollow body is inexpensive to manufacture as a pure turned part. The front threaded portion 25a of the closure piece continues rearward in a cylindrical portion 25b with a reduced outside diameter. At the end of this cylindrical section 25b is a head piece 26 which is initially somewhat reduced in diameter compared to the closure piece, but which has a conical thickening 28 in its rear region, which in turn is followed by a cylindrical section 27 of the head piece with a larger diameter. In this way, a type of groove results between the conical thickening 28 of the head piece and the cylindrical area 25 of the closure piece in the area of the reduced diameter 26 of the head piece. The head piece 26 is firmly connected to the firing pin 33 located inside the locking piece 25. To tension the firing pin by pulling out the head piece, the tension lever 23 can be folded in the direction of the arrow, the lower, approximately U-shaped, tension bracket 23 a of the tension lever sliding over the inclined surface of the conical extension 28, first pulling the head piece 26 out by a few millimeters and then finally End of the head piece 27 releases, so that the firing pin strikes the cartridge 16 by the spring force and ignites the propellant charge 17.
Der Aufbau des Verschlußstücks 25 geht aus der vergrößerten Darstellung gemäß Fig. 3 deutlicher hervor. Der zylindrische Abschnitt 25b des Verschlußstücks 25 nimmt axial beweglich den Schlagbolzen 33 auf, wobei der
Schlagbolzen 33 in seinem hinteren Abschnitt mit geringere Querschnitt in einer Hülse 35 mit L-förmigem Querschnitt aufgenommen ist. Diese Hülse 35 ist von einer Druckfeder 36 umgeben., für deren hinteres Ende die Spannmutter 37 als Widerlager dient. Der Schlagbolzen 33 weist an seinem vorderen Ende eine schmale Spitze 33a auf, die auf die Patrone aufschlägt. Durch Zurückziehen des Kopfstücks 26, 27 wird die Druckfeder 36 gespannt.The structure of the closure piece 25 is clearer from the enlarged view of FIG. 3. The cylindrical portion 25b of the closure piece 25 axially movably receives the firing pin 33, the Firing pin 33 is received in its rear section with a smaller cross section in a sleeve 35 with an L-shaped cross section. This sleeve 35 is surrounded by a compression spring 36, for the rear end of which the clamping nut 37 serves as an abutment. The firing pin 33 has a narrow tip 33a at its front end which strikes the cartridge. The compression spring 36 is tensioned by pulling back the head piece 26, 27.
Der Meßvorgang der erfindungsgemäßen Gasdruckmeßvorrichtung wird anschließend unter Bezugnahme auf Fig. 2 erläutert. Der Meßlauf 11 weist in seinem hinteren im Außendurchmesser erweiterten Abschnitt eine Radialbohrung 30 auf, die in Höhe der eingeschobenen zu messenden Patrone liegt, und die mit dem Inneren der Laufbohrung 14 des Meßlaufs 11 in Verbindung steht. Der Gasdruck wirkt dann durch die Radialbohrung 30 auf den Schaft eines Meßkolbens 19, der in einem Meßzylinder 18 nach oben hin - also radial im Bezug auf den Meßlauf - beweglich angeordnet ist, wobei im Ruhezustand der Kopf 32 des Meßkolbens 19 an einem Absatz der Innenbohrung des Meßzylinders 18 anliegt. In eine radiale Gewindebohrung des Gehäusekörpers 10 ist eine Büchse 21 mit Innengewinde eingesetzt, die wiederum einen Flansch 34 aufweist, an dem das obere Ende des Meßzylinders 18 gehalten wird. In dasThe measuring process of the gas pressure measuring device according to the invention is subsequently explained with reference to FIG. 2. The measuring barrel 11 has a radial bore 30 in its rear section, which has an enlarged outer diameter, which lies at the level of the inserted cartridge to be measured, and which is connected to the inside of the barrel bore 14 of the measuring barrel 11. The gas pressure then acts through the radial bore 30 on the shaft of a measuring piston 19, which is arranged in a measuring cylinder 18 so that it can move upwards - i.e. radially with respect to the measuring run - with the head 32 of the measuring piston 19 on a shoulder of the inner bore in the idle state of the measuring cylinder 18 is present. A bushing 21 with an internal thread is inserted into a radial threaded bore of the housing body 10, which in turn has a flange 34 on which the upper end of the measuring cylinder 18 is held. In the
Innengewinde 21a der Gewindebüchse ist eine Rändelschraube 22 eingeschraubt, so daß die radiale Bohrung 30 nach außen hin geschlossen ist. An der Oberseite des Kopfs 32 des Meßkolbens einerseits und an der stirnseitigen Widerlagerfläche 31 der Rändelschraube 22 andererseits liegt ein Stauchkörper 29 aus Kupfer oder dergleichen an. Die Rändelschraube 22 kann ebenfalls ein aus Dural gefertigtes Drehteil sein. Durch den Gasdruck der Explosion bei Abschuß des Geschosses, der sich durch die Radialbohrung 30 fortpflanzt, wird der Kopf 32 des Meßkolbens 19 nach oben gedrückt und damit der Stauchkörper 29 gestaucht. Das Maß der Stauchung des Stauchkörpers 29 läßt dann auf den Gasdruck beim Abschuß schließen, dieser Zusammenhang kann
z. B. aus einer Tabelle ablesbar sein. Mit Hilfe der konstruktiv einfach gehaltenen erfindungsgemäßen GasdruckmeßVorrichtung, die aus wenigen mit geringem Aufwand zu fertigenden Teilen besteht, läßt sich folglich in einfacher Weise der Gasdruck von Patronen bestimmen.
Internal thread 21a of the threaded bushing has a knurled screw 22 screwed in, so that the radial bore 30 is closed to the outside. On the top of the head 32 of the volumetric flask on the one hand and on the end abutment surface 31 of the knurled screw 22 on the other hand there is a compression body 29 made of copper or the like. The knurled screw 22 can also be a turned part made of dural. Due to the gas pressure of the explosion when the projectile is fired, which propagates through the radial bore 30, the head 32 of the measuring piston 19 is pressed upward and the compression body 29 is compressed. The degree of compression of the compression body 29 then indicates the gas pressure when firing, this connection can z. B. be readable from a table. With the help of the structurally simple gas pressure measuring device according to the invention, which consists of a few parts that can be manufactured with little effort, the gas pressure of cartridges can thus be determined in a simple manner.
