Description

Einrichtung zum stetigen Pressen von warm verformbaren Werkstoffen Bekanntlich vereinigen sich bei jeder Bleipresse die innerhalb der Presse geteilten Bleiströme in der Preßkammer zu einem einheitlichen Rohr, wenn dabei die Entstehung von Oxydschicchten oder das Eindringen von Fremdkörpern verhindert wird.Device for the continuous pressing of hot-formable materials As is well known, in every lead press the parts divided within the press are united Lead flows in the bale chamber to form a unitary tube when it does so Oxydschichchten or the penetration of foreign bodies is prevented.

Eine ausreichende Nahtbildung wird dabei mit Hilfe einer relativen Bewegung zwischen den in der Presse geteilten Bleiströmen erstrebt, oder es werden überlappte, schräg oder bogenförmig durch den Bleimantel hindurch verlaufende Nähte geformt.Sufficient seam formation is achieved with the help of a relative Movement between the lead streams divided in the press is sought, or it will be overlapped, oblique or arched seams running through the lead sheath shaped.

Bei der Herstellung von mehrwandigen Hohlkörpern, z. B. aus mehreren ineinandergesteckten Rohren oder aufeinandergelegten Blechstreifen, die zu Rohren zusammengebogen werden, ist es zwar üblich, die Nähte der beiden Rohre versetzt zueinander anzuordnen; Bleimäntel oder -rohre sind aber auf diese Weise bisher nicht erzeugt worden.In the production of multi-walled hollow bodies, e.g. B. from several nested tubes or sheet metal strips placed one on top of the other to form tubes are bent together, it is common to offset the seams of the two tubes to be arranged to each other; Lead jackets or pipes are not in this way so far has been generated.

In dem Patent 714220 ist eine Vorrichtung zur Herstellung von ummantelten Kabeln beschrieben, bei welcher ein thermoplastischer Stoft, insbesondere Blei oder eine Bleilegierung, durch eine den Preßdruck erzeugende, zur Hälfte rechts- und zur anderen Hälfte linksgängige Treibschraube der in der Mitte der Treibschraube liegenden Preßkammer zugeführt wird. Eine. derartige Vorrichtung ist in Abb. r schematisch dargestellt. Das fertiggepreßte Rohr besteht bei dieser symmetrischen Anordnung aus zwei ineinanderliegenden konzentrischen Rohren, die zu einem einheitlichen Rohr verschweißt sind. Der Weg der Bleiströme - innerhalb der Preßkammer und die Rohrbildung sind schematisch in Abb. 2 dargestellt. Wie in dem Patent 714 220 angegeben ist, können die Wände der Prcßkammer mit radial stehenden Rippen versehen werden, um ein Verdrehen des Bleistromes zu vermeiden. Über die besondere Art der Anordnung dieser Rippen ist aber nichts weiter darin erwähnt. Gemäß der Erfindung werden die gegen- überstehenden Rippen der beiden rechts- und linksseitigen Treibkammern gegeneinander versetzt. Das hat den Vorteil, daß die in bei- den Bleiströmen durch die Rippen gebildeten Nähte nicht übereinanderliegen. Werden z. B. in jeder Kammerhälfte zwei Stege vorgesehen und m4 9o- gegeneinander versetzt, so liegen die Nähte gemäß Abb.3 gegeneinander ver- setzt. Die Nähte sind in der Regel unschäd- lich, weil sie sich wieder schlcf)en. '%`"ird aber durch einen Freni,dkörper in einem Blei- strom eine Fehlstelle erzeugt, so kann diese niemals durch den ganzen Mantel durchdrin- gen, wenn die Nähte gegeneinander versetzt sind. Daraus ergibt sich eine wesentlich grö- ßere S.:icherheit des Kabelmantels gegeniiber den bekannten Ausführungen. In the patent 714220 a device for the production of sheathed cables is described, in which a thermoplastic material, in particular lead or a lead alloy, by means of a right-hand drive screw, half left-hand and half left-hand screw, of the pressing chamber located in the middle of the drive screw is fed. One. such a device is shown schematically in Fig. r. In this symmetrical arrangement, the finished-pressed pipe consists of two concentric pipes lying one inside the other, which are welded to form a single pipe. The path of the lead flows - within the compression chamber and the pipe formation are shown schematically in Fig. 2. As indicated in the 714,220 patent, the walls of the press chamber can be provided with radially extending ribs in order to twist the flow of lead to avoid. About the special kind of The arrangement of these ribs is nothing further mentioned therein. According to the invention, the opposite protruding ribs of the two right and left-sided propulsion chambers against each other offset. This has the advantage that the the flow of lead formed by the ribs Seams do not overlap. Are z. B. two bars are provided in each half of the chamber and m4 9o- offset from one another, so lie the seams against each other as shown in Fig. puts. The seams are usually not damaged because they are sleeping again. '% `" ird but by a Freni, the body in a lead electricity generates a defect, it can never penetrated through the whole coat- if the seams are offset against each other are. This results in a significantly larger Outer side: security of the cable jacket against the known designs.
