Description

Verfahren zur Herbeiführung eines gleichmäßigen Bleiflusses bei der Herstellung von Bleirohren, insbesondere von Kabelmänteln Es sind Verfahren bekannt, bei denen das der Preßkammer .einer Bleipresse in flüssigem Zustand unter Druck seitlich bei a (Abb. i) zufließende Blei auf dem Wege zum Mundstück b bis zum Plastischwerden abgekühlt wird. Es sind dazu Vorrichtungen vorgeschlagen worden, bei denen :diese Kühlung durch ringförmig die Preßkammer umgebende Elemente erfolgt. Bei diesem Verfahren wird ein einwandfreies Rohr nur erzielt, wenn die Temperatur des Bleies im zylindrischen, Teil c im ganzen Querschnitt überall gleich ist, andernfalls schiebt sich das Rohr 'einseitig vor und wird beim Austritt un@.ymmetrisch. Das bei a eintretende Blei umfließt dabei den Dornhalter d. Die Wärmebedingungen in den Punkten e und f sind unter Umständen sehr verschieden, wodurch sich Temperaturunterschiede im Blei ergeben, die, da das Blei an der Grenze des festen und flüssigen Zustandes ist, große Unterschiede in der Strömung hervorrufen können.Process for bringing about an even flow of lead in the Production of lead pipes, in particular of cable sheaths. Methods are known in which the press chamber .ein lead press in a liquid state under pressure Lead flowing in laterally at a (Fig. i) on the way to the mouthpiece b until it becomes plastic is cooled. To this end, devices have been proposed in which: these Cooling takes place through elements surrounding the compression chamber in a ring shape. In this procedure a perfect pipe can only be achieved if the temperature of the lead in the cylindrical, Part c is the same everywhere in the entire cross-section, otherwise the pipe will slide 'front on one side and becomes un @ .ymmetrical on exit. The lead entering at a flows around the mandrel holder d. The heat conditions in points e and f are possibly very different, which results in temperature differences in the lead, which, since the lead is at the limit of the solid and liquid state, great differences in the current.

Gemäß der Erfindung wird ein Temperaturausgleich und damit ein gleichmäßiger Bleifluß gewährleistet, indem die Kühlung nicht durch ringförmige, sondern durch axial unterteilte Kühlelemente erfolgt. Abb. 2 zeigt einen 'Schnitt einer beispielsweisen Ausführung. Die Oberfläche des Preßkopfes ist zeit sektorförmigen Kühlelementen g umgeben. Das Kühlwasser tritt an einem Ende durch getrerinte Leitungen, die durch Ventile l regelbar sind, ein, während der Abfluß als Ring lt gemeinsam ist. Der Abfluß kann jedochauch z. B. über Kontrolltrichter getrennt geführt werden. Durch Regelung der Ventile,(. ist es möglich,, die Kammer nach Belieben so zu kühlen, daß das Blei überall eine gleichmäßige Temperatur bzw. einen gleichmäßigen Fluß erhält. Die Wärmekontrolle kann z. B. durch Thermoelem.ente m erfolgen. Gemäß der Erfindung kann die Regelung der Ventile l durch die Th.ermoelemente m selbsttätig gesteuert werden.According to the invention, a temperature equalization and thus a uniform flow of lead is ensured in that the cooling takes place not through annular, but through axially subdivided cooling elements. Fig. 2 shows a section of an exemplary embodiment. The surface of the press head is surrounded by sector-shaped cooling elements g. The cooling water enters at one end through separate lines which can be regulated by valves l, while the drain is common as a ring lt. However, the drain can also be e.g. B. be performed separately via control funnel. By regulating the valves it is possible to cool the chamber at will so that the lead has an even temperature or an even flow everywhere In accordance with the invention, the regulation of the valves l can be controlled automatically by the Th.ermoelemente m.

In gleicher Weise wie von außen kann auch die Kühlung vom Dornhalter aus erfolgen. Zu diesem Zwecke sind dort ebenfalls unterteilte Kühlelemente i untergebracht. Die Zuführung des Kühlwassers erfolgt durch im Innern der Elemente liegende Rohre k. Die Kühlelemente können. statt von außen bzw. innen ebenso in Bohrungen des Körpers selbst untergebracht werden.In the same way as from the outside, the mandrel holder can also be cooled made from. For this purpose, subdivided cooling elements i are also accommodated there. The cooling water is supplied through pipes located inside the elements k. The cooling elements can. instead of from the outside or inside also in holes in the body be accommodated yourself.

Das Verfahren kann sowohl bei hydraulischen .als auch bei stetig arbeitenden Pressen angewandt werden.The method can be used with hydraulic as well as with continuously working Pressing can be applied.
