Description

Zündhütchen aus Aluminium Bekanntlich werden Zündsatzkapseln aus Aluminium und Aluminiumlegierungen für Sprengpatronen mit .einer Oxydschicht überzogen, damit bei der Sprengwirkung das darunter befindliche Metall nicht zum Glühen kommt, da sonst vorhandene Grubengase zur Entzikndung kommen. Nach der Erfindung, die in der Hauptsache Zündsatzkapseln aus Aluminium für Geschoßmunition zum Gegentand hat, gelingt ies, -nun die Zündsatzkapseln vor dem Durchschmelzen zu bewahren, wenn die innere Bodenfläche der Zündsatzkapsel mit einem wärmehemmenden Werkstoff abgedeckt ist.Primer made of aluminum It is well known that primer caps are made of aluminum and aluminum alloys for explosive cartridges coated with an oxide layer with it the metal underneath does not glow during the explosive effect, because otherwise existing mine gases can ignite. According to the invention, which in the The main thing is that it has primer capsules made of aluminum for projectile ammunition, If this succeeds, the primer capsules will now be prevented from melting through if the inner bottom surface of the primer capsule covered with a heat-retardant material is.

Erfindungsgemäß, lassen sich Einlagen aus Metallplättchen verwenden. Das Metallplättchen hat den Vorteil; daß es bei der auftretenden Verformung der Zündsatzkapsel, hervorgerufen durch den Schlagbolzen, nicht einreißt. Gleichzeitig verhindert es, daß die Glühtemperatur des Zündsatzes unnüttelbar auf dem Aluminiumboden entsteht, wodurch das Durchschmelzen des Aluminiumbodens unterbleibt. Insbesondere fand ein Plättchen aus Eisen wegen des höheren Schmelzpunktes gegenüber Aluminium Verwendung.According to the invention, inserts made of metal platelets can be used. The metal plate has the advantage; that it occurs when the deformation of the Primer capsule, caused by the firing pin, does not tear. Simultaneously it prevents the glow temperature of the primer from shaking on the aluminum base arises, whereby the melting of the aluminum floor does not occur. In particular found a plate made of iron because of its higher melting point compared to aluminum Use.
