Description

Anordnung zur Steigerung der Lebensdauer von gezogenen Schußwaffen. Bekanntlich hängt die Treffsicherheit beim Schießen mit gezogenen Schußwaffen, insbsondere Handfeuerwaffen, in hohem Maße von der Beschaffenheit des Laufend#-s an der Kante der Mündung und in deren Nähe ab. Andererseits ist gerade die Mündungskante in besonderem Maße der Gefahr d-r Abnutzung beim Reinig°n der Waffe ausgesetzt und wird auch durch Schläge oder Stöße leicht beschädigt.Arrangement to increase the service life of rifled firearms. As is well known, accuracy depends on shooting with guns drawn, in particular Small arms, largely due to the nature of the running # -s on the verge the mouth and in its vicinity. On the other hand, just the edge of the mouth is special Measures and is exposed to the risk of wear and tear when cleaning the weapon Slightly damaged by blows or bumps.

Gemäß der Erfindung besteht nun die Innenwand des Laufes in der unmittelbaren Nähe der Mündung, insb; sondere an der Übergangskante zwischen dem Lauf und der Mündungsebene, aus härterem Material, indem der Lauf an dieser Stelle bis in größere oder geringere Tiefe gehärtet ist. Der gezogene hintere Teil des Laufes bleibt ungehärtet, um die Beanspruchungen durch den Gasdruck beim Schießen ohne das Auftreten von Rissen auszuhalten. An sich ist es bereits bekannt, das Rohr aus Teilen von verschiedenem Material herzustellen, damit der hintere, den größten Gasdruck erfahrende Laufteil fester ist. Es ist aber nicht bekannt, daß durch Härtung des äußersten Laufendes die Lebensdauer und Treffsicherheit der Waffe in e_nfachster Weise vergrößert werden könne, während im übrigen auch der gezogene Laufteil ungehärtet bleiben kann.According to the invention, there is now the inner wall of the barrel in the immediate Near the mouth, esp; especially at the transition edge between the barrel and the Muzzle level, made of harder material, putting the barrel at this point up into larger ones or shallower depth is hardened. The drawn rear part of the barrel remains unhardened, to cope with the stresses caused by the gas pressure when shooting without cracks occurring to endure. It is already known per se, the pipe from parts of different Produce material so that the rear running part, which experiences the greatest gas pressure is more solid. However, it is not known that by hardening the extreme end of the barrel the lifespan and accuracy of the weapon can be increased in the simplest way while the drawn barrel part can also remain unhardened.
