Description
Verfahren zum Schmieren der Bleikammer und ihres Inhaltes von Pressen für Bleiröhren und Bleimäntel durch Zuführen von Schmiermaterial zwischen Preßgut und Preßkammer. Das Einführen von Schmierflüssigkeit zwischen Preßgut und Preßkammer bei Pressen für Bleiröhren ist allgemein bekannt. Hierbei erfolgt das Einführen der Schmierflüssigkeit während des ganzen Preßvorganges, und zwar mit einem Druck, der gleich oder größer als der Arbeitsdruck im Zylinder sein muß. Auch müssen bei diesen bekannten Verfahren Schlitze o. @dgl. in der Matrize eingearbeitet sein, um Raum zu schaffen, und es wird auch nur eine geringe Ringfläche geschmiert.Process for lubricating the lead chamber and its contents in presses for lead pipes and lead jackets by feeding lubricant between the pressed material and press chamber. The introduction of lubricating fluid between the material to be pressed and the pressing chamber in presses for lead pipes is well known. This is where the introduction takes place the lubricating fluid during the entire pressing process, with a pressure which must be equal to or greater than the working pressure in the cylinder. Also have to these known methods slots o. @ the like. be incorporated in the die, to create space, and only a small area of the ring is lubricated.
Bei dem den Gegenstand der vorliegenden Erfindung bildenden Verfahren zum Schmieren der Bleikammer und ihres Inhaltes von Pressen für Bleiröhren und Bleimäntel durch Zuführen von Schmiermaterial zwischen Preßgut und Preßkammer ist das Erfindumgsmerkmal darin zu :erblicken, daß -das Einführen. von Schmiermaterial vor jedem neuen Kodlbenhube erfolgt.In the process forming the subject of the present invention for lubricating the lead chamber and its contents of presses for lead pipes and lead jackets by supplying lubricating material between the material to be pressed and the pressing chamber is the feature of the invention in it to: behold that -the introduction. of lubricating material before each new lift he follows.
Die Erfindung beruht auf der Nutzbarmachung der Tatsache, daß nach jedem Arbeitshübe beim Rückgang des Kolbens der noch in der Preßkammer befindliche Bleikern zusammenschrumpft und dadurch ein geringer Hohlraum zwischen, Bleimasse und Kammerwandung entsteht, der das Einführen .von Schmiermaterial ermöglicht. Hierdurch fällt das bisher erforderliche Einarbeiten- von Schlitzen in die Matrize, um erst Raum zu schaffen, fort. Es bleibt beim vorliegenden Verfahren die Matrize intakt, der erforderliche Hohlraum wird durch; die Schrumpfung des Bleies gebildet, da beim Aufhören des Kolbenhubes ein Erkalten :des Bleikerns eintritt. Auch wird beim Erfindungsgegenstand das Schmiermaterial nur mit normalem Schmierdruck zugeführt und nicht nur eine geringe Ringfläche, sondern der ganze Innenraum der Matrizenwandung oder der Bleikern in seinem ganzen Umfange geschmiert.The invention is based on the utilization of the fact that after each working stroke when the piston retracts the one that is still in the bale chamber Lead core shrinks and thus a small cavity between, lead mass and chamber wall is created, which enables the introduction of lubricating material. Through this the previously required machining of slots in the die falls in order to only To create space, away. With the present method, the matrix remains intact, the required cavity is through; the shrinkage of the lead formed because of the The piston stroke stops and cools down: the lead core occurs. Also with the subject matter of the invention the lubricating material is only supplied with normal lubricating pressure and not just a low one Ring surface, but the entire interior of the die wall or the lead core in lubricated to its full extent.
Als wichtiges Ergebnis der Erfindung kommt in Betracht, daß durch dieses Verfahren ein in qualitativer Hinsicht vorzügliches, fast durchweg homogenes Preßgut erzielt wird.An important result of the invention is that through this process is excellent in terms of quality, and is almost entirely homogeneous Preßgut is achieved.
Es sei noch erwähnt, daß vor dem ersten Preßhub die Schmierung der Kammer während der Montage erfolgen kann.It should also be mentioned that the lubrication of the Chamber can be done during assembly.
Auf der Zeichnung ist schematisch die Bleikammer einer Bleirohr- und Mantelpresse irr. Schnittdargestellt.In the drawing, the lead chamber of a lead pipe and is schematically Jacket press irr. Shown in section.
ca ist der P.reßblock mit innen. sitzender Kammer b. c ist der untere Zylinderteil mit punktiert eingezeichnetem Kolben d. Die Verbindung von Zylinder c mit der Bleikammer b erfolgt durch den trichterförmigen Hohlraum e. .ca is the pressure block with inside. sitting chamber b. c is the lower one Cylinder part with dotted piston d. The connection of cylinder c with the lead chamber b takes place through the funnel-shaped cavity e. .
Beispielsweise ist ein Kabel f gewählt, welches am Mundstück g mit einem Bleimantel h umpreßt wird.For example, a cable f is selected which is attached to the mouthpiece g with a lead jacket h is pressed around.
Die schematische Darstellung zeigt den Preßvorgang nach Beendigung des ersten Hubes und nach Erkalten der noch in der Kammer b und im Hohlraum e befindlichen Bleimasse i. Mit k ist der vorgenannte, entstehende Hohlraum zwischen Bleimasse und Kammerwandung bezeichnet, welchem in beliebiger Weise Schmiermaterial zugeführt werden kann, z. B. dadurch, daß das Schmiermaterial in den Schmierkanall, nachdem eine in denselben. eingesetzte Dichtungsnadelm nach Beendigung des Hubes herausgeschraubt ist, eingeführt und durch die Dichtungsnadel der VerschluB wieder hergestellt wird.The schematic representation shows the pressing process after completion of the first stroke and after the lead mass i, which is still in the chamber b and in the cavity e, has cooled down. With k the aforementioned, resulting cavity between lead mass and chamber wall is referred to, which lubricant can be supplied in any way, z. B. in that the lubricating material in the lubrication channel after one in the same. The sealing needle inserted is unscrewed after the end of the stroke, inserted and the lock is re-established through the sealing needle.
