  Verfahren zur Herstellung von Trieurbeeh. 



   Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Trieurblech und besteht darin, dass die Zellen in hartes Blech unter Verwendung einer das Blech von unten um die Zelle herum anschneidenden Matrize eingestanzt werden, deren Stanzöffnung einen dem oberen Zellendurchmesser angenäherten Durchmesser besitzt. 



   Hierdurch ergibt sich gegenüber den bisherigen Verfahren zur Herstellung von Trieurblechen der Vorteil, hartes Blech von geringer Dicke verwenden zu können und trotzdem Zellen von grosser Tiefe mit durchgehend scharfen Rändern und völlig geschlossenem Boden zu erzielen. Ausserdem ist der Vorteil erzielt, die Zellen möglichst nahe nebeneinanderliegend einstanzen zu können und somit bei vollständig gesicherter langer Brauchbarkeit die Leistungsfähigkeit des Trieurbleches zu erhöhen. 



   In der Zeichnung ist die Herstellung eines Trieurbleches aus hartem Blech gemäss der Erfindung veranschaulicht. 



   Die als Unterlage für das mit'Zellen zu versehende, z. B. Eisenblech a, dienende Matrize b ist mit einer Aussparung oder Öffnung c versehen, welche in ihrem Durchmesser angenähert in der Grösse des oberen Durchmessers der herzustellenden Zelle ausgeführt ist, so dass beim Einstanzen der Zelle mittels des'Stempels d die Fasern des um die sich bildende Zelle liegenden Bleches an der oberen Seite nicht mit nach unten gedrückt werden, sondern nur der Zellenboden unter allseitigem Anschneiden in die Öffnung c eingedrückt wird und somit eine Zelle von grosser Tiefe mit durchgehend   schartem   Rand und angeschnittenem und dabei völlig geschlossenem Boden entsteht.

  Process for making trieurbeeh.



   The invention relates to a method for producing door sheet metal and consists in that the cells are punched into hard sheet metal using a die which cuts the sheet metal from below around the cell, the punching opening of which has a diameter approximating the upper cell diameter.



   This has the advantage over the previous methods for producing door plates that hard plate of small thickness can be used and cells of great depth with consistently sharp edges and a completely closed bottom can be achieved. In addition, the advantage is achieved that the cells can be punched in as close to one another as possible and thus the efficiency of the door plate can be increased while the long usability is completely assured.



   In the drawing, the production of a door plate from hard sheet metal according to the invention is illustrated.



   The as a base for the mit'Zellen to be provided, z. B. iron sheet a, serving die b is provided with a recess or opening c, the diameter of which is approximately the size of the upper diameter of the cell to be produced, so that when punching the cell by means of the stamp d the fibers of the The sheet metal that is being formed is not pressed down on the upper side, but only the cell bottom is pressed into the opening c, cutting on all sides, thus creating a cell of great depth with a continuously sharp edge and a truncated and completely closed bottom.
