Description
Verfahren zum Regeln der Preßgeschwindigkeiten in Rohrstrang-, insbesondere Kabelummantelungspressen mit gegenläufig zusammenwirkenden Preßstempeln Es ist bekannt, Rohre, insbesondere Kabelummantelungen aus Aluminium, in der Weise mittels hydraulischer Pressen herzustellen, daß das in Blockform eingebrachte Aluminium dem Preßwerkzeug aus zwei auf entgegengesetzten Seiten des ruhenden Preßkopfes angeordnetenAufnehmern mit gegenläufig zusammenwirkenden Preßstempeln zugeführt wird. Es ist, z. B. bei Bleikabelpressen, auch bereits bekannt, Vorrichtungen vorzusehen, mit deren Hilfe die beiden Preßstempel ihre Geschwindigkeit gegenseitig regeln, beispielsweise derart, daß jeweils der langsamer laufende Stempel die Geschwindigkeit des anderen Stempels verringert. Eine Regelung der Stempelgeschwindigkeiten ist nämlich notwendig, damit die beiden Aufnehmer zur Herstellung einwandfreier Rohre von beiden Seiten stets gleiche Preßgutmengen der Matrize zuführen, wofür die Stempel stets gleiche Geschwindigkeiten einhalten müssen.Method for regulating the pressing speeds in pipe string, in particular Cable sheathing presses with press rams that work in opposite directions It is known Pipes, in particular cable sheathing made of aluminum, in the manner by means of hydraulic Press to produce that the aluminum introduced in block form to the pressing tool from two transducers arranged on opposite sides of the stationary press head is supplied with rams cooperating in opposite directions. It is Z. B. at Lead cable presses, also already known, to provide devices with their help the two rams regulate their speed mutually, for example in such a way that that the slower running stamp is the same as the speed of the other stamp decreased. A regulation of the punch speeds is necessary in order to do this the two transducers for the production of perfect pipes from both sides Feed the same amount of material to the die, for which the punches always have the same speeds must adhere to.
Die Erfindung bezweckt nun, die Zuführung gleicher Werkstoffmengen aus beiden Aufnehmern mit verhältnismäßig einfachen Mitteln sicherzustellen. Sie sieht ein Regelverfahren vor, das darin besteht, daß der eine Preßstempel gegen einen höher erhitzten Preßblock arbeitet und abhängig von- seiner Preßgeschwindigkeit nur die Geschwindigkeit des entgegengesetzten Preßstempels bzw. -plungers gesteuert wird.The invention now aims to supply the same amounts of material to ensure from both sensors with relatively simple means. she provides a control method, which consists in the fact that the one press ram against a higher heated press block works and depending on its pressing speed only the speed of the opposite ram or plunger is controlled will.
Es kann dann eine hydraulische Presse mit zwei gleichen Aufnehmern verwendet werden, die von zwei gleichen Druckkolben betätigt werden.A hydraulic press with two identical pickups can then be used used, which are operated by two identical plungers.
Die Vorrichtung zur Regelung der Geschwindigkeit des einen Aufnehmers kann in an sich bekannter Weise eine Drosselung des Flüssigkeitszulaufes in den zugehörigen Druckzylinder bewirken. Es ist aber auch möglich, zur Regelung der Geschwindigkeit zusätzlich einen kleineren Hilfszylinder zu verwenden, wie er bereits vorgeschlagen worden ist.The device for regulating the speed of one transducer can in a known manner throttling the liquid inlet in the cause associated pressure cylinder. But it is also possible to regulate the speed additionally to use a smaller auxiliary cylinder, as already suggested has been.
