Description

Bleipresse mit zwei Preßstempeln Die vorliegende Erfindung betrifft eine Verbesserung der Herstellung von Bleimänteln oder -rohren (beispielsweise Bleikabelmänteln) auf Pressen mit zwei Preßstempeln. Nach der Erfindung sollen bei diesen Pressen die beiden Preßstempel in ihrer Längsrichtung gegeneinander versetzt und die Einfüllöffnungen der Aufnehmer in verschiedenen Höhenlagen angebracht werden, so daß durch die Nachfüllung der Aufnehmer etwa verursachte Trennschichten des Mantelmetalls im eigentlichen Preßraum niemals in unmittelbarer Nachbarschaft auftreten können. Durch diese Verteilung der Trennschichten wird das Auftreten von schwachen Stellen im Metallmantel stark vermindert.Lead press with two dies The present invention relates to an improvement in the production of lead sheaths or pipes (e.g. lead cable sheaths) on presses with two rams. According to the invention in these presses the two rams offset from one another in their longitudinal direction and the filling openings the transducer can be installed at different heights, so that the refill the transducer, for example, caused separating layers of the cladding metal in the actual Press room can never occur in the immediate vicinity. Through this distribution of the separating layers, the appearance of weak points in the metal jacket becomes strong reduced.

Die Abbildung zeigt eine schematische Darstellung der in Frage kommenden Bleipressenanordnung. Es bedeuten a und b die Preßstempel, die miteinander durch eine Querverbindung fest verbunden sind. Diese Querverbindung kann in bekannter Weise auf dem Ende der Kolbenstange eines Tauchkolbens sitzen, der die Preßstempel bewegt. Die Aufnehmer sind mit c und d bezeichnet; e und f sind die Strecken, um welche die Preßstempel bzw. die Aufnehmeröffnungen in der Längsrichtung gegeneinander versetzt sind. Mit g ist der hohle Dorn bezeichnet, durch den die Kabelseele, die mit einem Bleimantel umgeben -werden soll, hindurchtritt.The figure shows a schematic representation of the lead press arrangement in question. A and b denote the ram, which are firmly connected to one another by a cross connection. This cross connection can sit in a known manner on the end of the piston rod of a plunger which moves the ram. The sensors are labeled c and d; e and f are the distances by which the ram or the receiving openings are offset from one another in the longitudinal direction. The hollow mandrel is designated by g, through which the cable core, which is to be surrounded by a lead sheath, passes.

Die ungleich hohe Auffüllung beider Aufnehmer mit Blei ist möglich, sobald als das in dem Innenraum der Bleimantelpresse befindliche Blei nicht mehr flüssig, sondern, wie es mit Rücksicht auf die Rohr- bzw. Mantelbildung beim Austritt aus der Presse erforderlich ists fest bzw. plastisch geworden ist.The unequal filling of both transducers with lead is possible, as soon as the lead in the interior of the lead jacket press is no more liquid, but as it is with regard to the tube or jacket formation at the outlet from the press is required it has become solid or plastic.
