Description

Die Membranen in Druckmeßgeräten, wie Meßdosen, Aneroiddosen usw., sind aus Blech hergestellt. Bel· der Herstellung und bei der Verwendung von Membriandruckmeßgeräten hat sich gezeigt, daß sich die Membranen- bzw. die Membrandosen verwerfen. Bei der Herstellung ist dies insofern nachteilig, als ein einwandfreies Löten wesentlich erschwert wird. Diese Nachteile sind offenbar im wesentlichendarauf zurückzuführen, daß die zur Herstellung der Membrandosen verwendeten Bleche einen bestimmten kristallinen Aufbau aufweisen, der von dem Auswalzen der Bleche herrührt. Die Eigenschaften der Membranen sind demzufolge, längs zur WaIzridhtung gesehen, anders als quer zur Walzrichtung.The membranes in pressure gauges, such as load cells, aneroid boxes, etc., are made of sheet metal. During the manufacture and use of membrane pressure measuring devices, it has been shown that discard the membrane or membrane cans. In the production, this is disadvantageous in that perfect soldering is made much more difficult. These drawbacks appear to be essentially on it due to the fact that the sheets used to manufacture the membrane cans have a certain have crystalline structure resulting from the rolling of the sheets. The properties the membranes are therefore along the WaIzridhtung seen differently than transversely to the rolling direction.

Der Erfindung liegt die Aufgabe zugrunde, die Nachteile der bekannten Membrandosen zu vermeiden. Die Erfindung besteht im wesentlichen darin, daß die Membranen aus im Kaltfließpreßverfahren hergestellten Blechen ausgeschnitten bzw. ausgestanzt wenden. Beim Kaltfließpreßverfahren so wird eine radiale Ausrichtung der Kristallstruktur erreicht und eine einseitige Walzausrichtung mit den beschriebenen Nachteilen vermieden. Die erfindungsgemäß hergestellten Membranen haben gleichmäßig gut federnde Eigenschaften. Die Herstellung der Dosen aus diesen Blechen ist ohne Schwierigkeiten möglich. Das unangenehme Verziehen und Verwerfen der bekannten Membranlbleche ist hierbei vermieden. Das Kaltftießpreß>verfahren kann dabei zweckmäßigerweise derart geleitet werden, daß eine •lange Kristallstruktur vermieden wird. Dadurch wird die Gef ahr beseitigt, die durch die Bildung zu ■langer Kristalle entstehen könnte.The invention is based on the object of avoiding the disadvantages of the known diaphragm cans. The invention consists essentially in the fact that the membranes are made in the cold extrusion process cut or punched out sheets. With the cold extrusion process like this a radial alignment of the crystal structure is achieved and a one-sided roller alignment with the described disadvantages avoided. The membranes produced according to the invention have uniform good resilience. The production of the cans from these sheets is straightforward possible. The unpleasant warping and warping of the known membrane sheets is here avoided. The cold extrusion process can expediently be conducted in such a way that a • long crystal structure is avoided. This removes the danger posed by education too ■ Long crystals could arise.

Zweckmäßigerweise werden die Membranflächen oder die im Kaltfließpreßverfahren hergestellten Bleche hochfrequenten Schwingungen ausgesetzt,The membrane surfaces or those produced by the cold extrusion process are expediently produced Sheet metal exposed to high-frequency vibrations,

um eine künstliche Alterung zu erzeugen. Bei der Anwendung von Hochfrequenzschwingungen oder Ultraschall 'kann die Temperaturhöhe und -dauer ■bei genauer Ausrichtung auf einzelne Stellen des Meßkörpers genau dosiert werden. Dadurch lassen sich die mechanischen, Eigenschaften-wesentlich, verbessern. to create artificial aging. In the Application of high frequency vibrations or ultrasound 'can change the temperature level and duration ■ be dosed precisely with precise alignment to individual points on the measuring body. Let through it the mechanical properties are significantly improved.

Das Verlöten der Membrandosen kann unter dem Einfluß hochfrequenter Schwingungen erfolgen, wobei gegebenenfalls auch die Lötung im Vakuum vorgenommen werden kann.The membrane cans can be soldered under the Influence of high-frequency vibrations take place, the soldering possibly also being carried out in a vacuum can be.
