Description

Metallmembran mit Verstärkungsring An einer Membran mit Verstärkungsring, die auf dem Wege der Warmherstellung. z. B. in Spritzguß, aus Metall gebildet ist, zeigt es sich oft, daß die eigentliche Membran nicht eben. sondern etwas gewölbt ist. Dies erklärt sich daraus, daß beim Abkühlen zuerst die dünne Membran und dann der Verstärkungsring erkaltet. Bei diesem Vorgang schrumpft der Verstärkungsring zusammen und drückt die Membran . durch.Metal membrane with reinforcement ring On a membrane with reinforcement ring, those on the way of hot production. z. B. in injection molding, is formed from metal, it often turns out that the actual membrane is not level. but somewhat arched is. This is explained by the fact that when cooling first the thin membrane and then the reinforcement ring cools down. During this process, the reinforcement ring shrinks together and presses the membrane. by.

Auf den verschiedensten Gebieten der Feinmechanik, z. B. bei Fernhörern, ist es aber unerläßlich oder erwünscht, daß die Membran einwandfrei plangespannt ist. Erfindungsgemäl'# wird daher nach dem Al)-kühlen der Verstärkungsring durch Eindrückungen erweitert.In a wide variety of fields of precision engineering, e.g. B. in the case of telephones, but it is essential or desirable that the membrane is properly tensioned flat is. According to the invention, the reinforcing ring is therefore through after the Al) cooling Impressions expanded.

Auf der Zeichnung ist eine solche Membran mit dem Verstärkungsring r und den Eindrückungen a in den Abb. r bis 3 dargestellt.Such a membrane with the reinforcement ring is shown in the drawing r and the indentations a in Figs. r to 3.
