Description

Verfahren zur Herstellung von gestanzten Gittern für Elektronenröhren Es ist bekannt, Gitter für Elektronenröhren durch Stanzen aus Blech derart herzustellen, daß parallele Verbindungsstege entstehen, die nachträglich hochgekantet werden.Process for the production of punched grids for electron tubes It is known to produce grids for electron tubes by punching from sheet metal in such a way that that parallel connecting webs are created, which are subsequently folded up.

Die Erfindung betrifft nun ein zur Herstellung von Gittern für Elektronenröhren dienendes Verfahren, das darin besteht, daß ein fortlaufender Streifen, dessen Breite der Länge bzw. Höhe der herzustellenden Gitter entspricht, derart gestanzt wird, daß ausgebogene oder U-förmige Verbindungsstege gebildet werden, worauf die letzteren zweckmäßig an ihrer Wurzel aufgekantet und nachher von dem Streifen die den Gittern entsprechenden Stücke abgeschnitten, schließlich die letzteren in die Endform gebracht werden.The invention now relates to a method for producing grids for electron tubes Serving method, which consists in making a continuous strip, the width of which corresponds to the length or height of the grid to be produced, is punched in such a way that that curved or U-shaped connecting webs are formed, whereupon the latter suitably edged up at their roots and then the bars from the strip cut off the appropriate pieces, finally the latter brought into the final shape will.

Die Abb. i und 2 zeigen zwei - Ausführungsformen des Streifens zur Herstellung von sogenannten Doppelkegelgittern, bei welchen zwischen zwei Randteilen ausgebogene (Abb. i) oder U-förmige Stege (Abb. 2) gebildet sind.Figs. I and 2 show two - embodiments of the strip for Production of so-called double cone grids, in which between two edge parts curved (Fig. i) or U-shaped webs (Fig. 2) are formed.

Zur Durchführung des Verfahrens wird ein Streifen benutzt, dessen Breite gleich ist der Höhe bzw. Länge der herzustellenden Gitter.To carry out the method, a strip is used, its Width is the same as the height or length of the grid to be produced.

In dem Streifen werden durch Ausstanzen die obengenannten Stege gebildet, die sodann an der Wurzel, d. h. an der Verbindungsstelle zwischen Steg und Randteil des Streifens, aufgekantet werden, so daß sie im Fertigzustand gegen den Glühfaden hin gerichtet sind. Nach dem Aufkanten werden die den Gittern entsprechenden Stücke abgeschnitten und diese sodann in die Endform des Gitters gebracht. Das beschriebene Verfahren hat die Vorteile, daß lediglich die zwischen den Stegen befindlichen Streifenteile abfallen, während der ganze übrige Streifen Gittermaterial bildet, und daß, abgesehen von der großen Materialersparnis, eine bedeutende Vereinfachung der Schnitte erzielt wird, die nicht mehr eine Vielzahl von feinen Stempeln aufweisen müssen.The above-mentioned webs are formed in the strip by punching out, which then at the root, d. H. at the junction between the web and the edge part of the strip, so that they are in the finished state against the filament are directed towards. After edging, the pieces corresponding to the grids are made cut off and then brought them into the final shape of the grid. The described The method has the advantages that only the strip parts located between the webs fall off while all the rest of the strip forms grid material, and that apart from the great savings in material, a significant simplification of the cuts is achieved that no longer have to have a large number of fine stamps.

PATENTANSPRUCH: Verfahren zur Herstellung von gestanzten Gittern für Elektronenröhren, dadurch gekennzeichnet, daß ein fortlaufender Streifen, dessen Breite der Länge bzw. Höhe der herzustellenden Gitter entspricht, derart gestanzt wird, daß ausgebogene oder U-förmige Verbindungsstege gebildet werden, worauf die letzteren an ihrer Wurzel aufgekantet und nachher von dem Streifen die den Gittern entsprechenden Stücke abgeschnitten, schließlich die letzteren in die Endform gebracht werden. Claim: A method for producing punched grids for electron tubes, characterized in that a continuous strip, the width of which corresponds to the length or height of the grids to be produced, is punched in such a way that bent or U-shaped connecting webs are formed, whereupon the latter on their Edged root and then cut off the pieces corresponding to the grids from the strip, finally bringing the latter into the final shape.
