Abstract

Three helmet shaped pressed steel shells are joined by adhesive bonding. The shells are made so that the rolling direction of each shell run differently. The shell enclosed by two other shells is hardened before bonding pref. by a nitriding process. The adhesive bonding material is a plastics resin. More than three shells can be used and the rolling fibre orientation need not differ. The resistance of the helmet or jacket against penetration by bullets is high.

Description

"Verfahren zur Herstellung von Schutzhelmen oder derglei-"Process for the production of protective helmets or similar

chen und nach dem Verfahren hergestellter Gegenstand" Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Schutzhelmen oder ähnlichen Gegenständen, wie Panzerwestenteilen aus Stahlblech. Derartige aus Stahlblech gepreßte Gegenstände sind bereits bekannt.Chen and article manufactured by the method "The invention refers to a process for the production of protective helmets or similar objects, like armored vest parts made of sheet steel. Such items pressed from sheet steel are already known.

Der Erfindung liegt nun die Aufgabe zugrunde, die Durchschlagsicherheit dieser Gegenstände gegen Beschuß zu erhöhen, ohne deren Gewicht und Kostenaufwand zu vergrößern.The invention is based on the problem of security against breakdown to increase these objects against fire without their weight and expense to enlarge.

Die Lösung dieser Aufgabe soll nach der Erfindung nun dadurch erreicht werden, daß mehrere, vorzugsweise drei aus Stahlblech in Helmfom oder entsprechende Endform gepreßte Stahlbleche so unter Zwischenfügung von Klebstoff zusammengepreßt werden, daß die Walzfaserrichtung dieser einzelnen Bleche vorzugsweise zueinander verschieden verlaufen, daß das mittlere in Helmform oder dergleichen Endform gepreßte Blech vor dem Zusammenpressen mit der anderen in Helmform oder dergleichen gepreßten Blechen vorzugsweise im Nitrierverfahren gehärtet wird.This object is now to be achieved according to the invention be that several, preferably three made of sheet steel in helmet form or equivalent Final form pressed steel sheets so with the interposition of glue are pressed together that the rolled grain direction of these individual sheets is preferred run different to each other that the middle in the shape of a helmet or the like Final shape pressed sheet metal before being pressed together with the other in helmet shape or like pressed sheet metal is preferably hardened in the nitriding process.

Der erfindungsgemäß hergestellte Gegenstand besteht aus vorzugsweise drei Stahlblechen, deren Walzfaserrichtungen tunlichst zueinander verschieden verlaufen und bei dem das mittlere Stahlblech aus an der Oberfläche, zweckmäßig im Nitrierverfahren, gehärtetem Stahl besteht und zwischen den einzelnen Blechen Klebstoffschichten, zweckmäßig aus Kunstharz, vorgesehen sind.The article produced according to the invention preferably consists of three steel sheets, the directions of which are as different as possible from one another and in which the middle steel sheet is made of on the surface, expediently in the nitriding process, hardened steel and adhesive layers between the individual sheets, suitably made of synthetic resin are provided.

Es sind bereits Panzerplatten bekannt (DBP 1 578 336), die aus mehreren aufeinanderliegenden Blechen bestehen und bei denen die Walzfaserrichtungen zueinander verschieden laufen.Armor plates are already known (DBP 1 578 336), which consist of several consist of sheets lying on top of one another and in which the directions of the rolled fibers are relative to one another run differently.

Hierdurch wird bereits die Durchschlagkraft aufschlagender Geschosse herabgesetzt (vergleiche DBP 1 578 336 und in den Akten liegende Berichte über Beschußversuche). Es ist aber auch bekannt, Panzerplatten herzustellen, bei denen die oberen und unteren Bleche aus zähem Stahl und die mittleren Bleche aus hartem Stahl bestehen. Solche Panzerplatten lassen sich nicht zu Schutzhelmen oder dergleichen pressen, da hierbei die inneren Bleche aus hartem Stahl zerspringen würden.This already increases the penetration power of impacting projectiles reduced (compare DBP 1 578 336 and reports on attempts at fire in the files). But it is also known to make armor plates, in which the upper and lower Sheets are made of tough steel and the middle sheets are made of hard steel. Such Armor plates can be not to protective helmets or the like press, as this would shatter the inner sheets made of hard steel.

Eine vorherige Erwärmung würde dem harten Stahl die Härte nehmen. Durch das erwähnte Verfahren nach der Erfindung ist es aber möglich, Schutzhelme oder dergleichen mit einer innenliegenden harten Stahlplatte herzustellen. Durch das erfindungsgemäße Verkleben der einzelnen vorher in Form gepreßten Platten ergibt sich eine besondere Elastizität des Helmes oder dergleichen, was weiterhin die Durchschlagkraft aufprallender Geschosse herabsetzt.A previous heating would take the hardness of the hard steel away. However, by the aforementioned method according to the invention, it is possible to use protective helmets or the like with an internal hard steel plate. By the inventive bonding of the individual plates previously pressed into shape results a special elasticity of the helmet or the like, which continues the penetration impacting projectiles.

Es ist nach der Erfindung auch möglich, mehr als drei Einzelbleche vorzusehen, wobei auch mehrere Einzelplatten aus hartem Stahl zwischen solchen aus zähem Stahl liegen können.It is also possible according to the invention to have more than three individual sheets to be provided, with several individual plates made of hard steel between those made tough steel.

Auch liegt es im Rahmen der Erfindung, wenn die Walzfasern der einzelnen Bleche zueinander nicht verschieden verlaufen.It is also within the scope of the invention if the rolled fibers of the individual Sheets do not run differently from one another.
