Description

Geschoß aus Kunstharz-Preßmasse für Ubungsmunition und Verfahren zur Herstellung desselben Die Erfindung hat ein Geschoß für übungsmunition aus Kunstharz-Preßmasse und ein Verfahren zur Herstellung derselben zum Gegenstand.Projectile made of synthetic resin molding compound for practice ammunition and method for Manufacture of the same. The invention has a projectile for training ammunition made of synthetic resin molding compound and a method of making the same as an object.

Um solche Geschosse nach dem Abschießen leicht zum Zerfall zu bringen, wurde bisher die Kunstharz-Preßmasse lediglich im Preßverfahren verformt. Es hat sich aber gezeigt, daß die so hergestellten Geschosse nur beschränkt Anwendung finden können. Infolge ihrer Beschaffenheit sind sie für automatische Waffen nicht geeignet. Durch die hohe Feuergeschwindigkeit solcher Waffen wird die Hitzeentwicklung so gesteigert, daß das Kunstharz im Preßling flüssig wird und dadurch eine Verstopfung der Züge im Lauf der Waffen eintritt.In order to easily disintegrate such projectiles after launching, So far, the synthetic resin molding compound has only been deformed in the molding process. It has but it has been shown that the projectiles produced in this way are only used to a limited extent can. Due to their nature, they are not suitable for automatic weapons. Due to the high rate of fire of such weapons, this is how the heat builds up increased that the synthetic resin in the compact becomes liquid and thereby a blockage of trains entering in the course of arms.

Durch die Erfindung werden diese Übelstände beseitigt. Das erfindungsgemäße Verfahren besteht darin, daß die Pzeßlinge in einer beheizten Form einem solchen kurzzeitigen Preßdruck unterworfen werden, der den Kern des Preßlings noch ungehärtet läßt und durch den Druck lediglich die Oberfläche verfestigt wird.The invention eliminates these inconveniences. The inventive The process consists in placing the process pieces in a heated form be subjected to short-term pressing pressure, which still uncured the core of the compact and the pressure only solidifies the surface.

Die hohe Hitzeentwicklung bei automatischen Waffen kann dem Preßling insofern nicht mehr schaden, als die gehärtete Oberfläche nicht nochmals flüssig wird und daher auch kein Verschmieren bzw. Verstopfen der Züge im Lauf der Waffen eintreten kann. Ein Weichwerden der Preßmas.se innerhalb bzw. unterhalb der gehärteten Oberfläche ist ohne Bedeutung, da das Geschoß bereits kurz nach dem Verlassen des Laufs der Fe-aerwaffe unter Einwirkung des Luftwiderstandes zu zerfallen beginnt. Die Anwendung des neuen Verfahrens kann in den gebräuchlichen Pressen mit Heizeinrichtung erfolgen.The high heat generated by automatic weapons can damage the compact No more damage insofar as the hardened surface does not become liquid again and therefore no smearing or clogging of the trains in the course of the weapons can occur. A softening of the molding material within or below the hardened one The surface is irrelevant, as the floor is shortly after leaving the The barrel of the Fe-aerwaffe begins to disintegrate under the action of air resistance. the The new process can be used in conventional presses with heating equipment take place.
