Description

Verfahren zur Herstellung von Preßmatrizen Die Erfindung bezweckt die Herstellung von Preßmatrizen für Trommeln, beispielsweise Siebtrommeln, aus Preßmasse mit pyramidenförmigen Löchern mit quadratischer oder rechteckiger Grundfläche. Um die Löcher in den Trommeln zu erzeugen, hatte man bisher am Matrizenmantel zylindrische Zapfen o. dgl. angebracht. Das bohren der Löcher für die Zapfen und das Einsetzen und Befestigen derselben in diese Löcher war aber umständlich und kostspielig. Außerdem war es nicht leicht, die Zapfen in eine für den Preßvorgang günstige genaue Stellung zu bringen. Besondere Schwierigkeiten ergaben sich dann, wenn nicht runde "Zapfen, sondern pyramidenförmige Ansätze an den Matrizenmantel erzeugt «-erden sollten.Process for the manufacture of press dies The invention aims the production of press dies for drums, for example sieve drums Molding compound with pyramid-shaped holes with a square or rectangular base. In order to create the holes in the drums, cylindrical ones were previously used on the die jacket Pin o. The like. Attached. Drilling the holes for the tenons and inserting them but fastening them in these holes was cumbersome and expensive. aside from that it was not easy to get the tenons into an exact position that was favorable for the pressing process bring to. Particular difficulties arose, if not round "cones, but pyramid-shaped projections should be produced on the die jacket.

Die Erfindung erleichtert nun die Herstellung der fraglichen Preßmatrizen dadurch, daß die Vorsprünge durch Eindrehen von parallelen kreisförmigen Rillen und Einhobeln oder Einfräsen von diese kreuzenden, mit den Mantellinien des Matrizenzylinders parallel verlaufenden -Nuten auf der Innenseite der Matrizen erzeugt werden.The invention now facilitates the manufacture of the press dies in question in that the projections by turning parallel circular grooves and planing or milling of these intersecting with the surface lines of the die cylinder parallel grooves are created on the inside of the dies.

Bei diesem Verfahren bietet die Herstellung der Preßmatrizen mit Anordnungen zum Einpressen pyramidenförmiger Löcher mit quadratischer oder rechteckiger Grundfläche keine Schwierigkeiten, und es läßt sich eine sehr genaue -Matrize schnell und billig erzeugen.In this method, the manufacture of the dies with arrays offers For pressing in pyramid-shaped holes with a square or rectangular base no trouble, and a very accurate die can be made quickly and cheaply produce.
