Description

Die Erfindung bezieht sich auf Einrichtungen zur Vulkanisation, vorzugsweise zur Vorwärmung, von Fahrzeugreifen oder anderen Gegenständen aus Gummi im hochfrequenten elektrischen Wechselfeld, bei denen die als Außenelektrode dienende Reifenform auf Erdpotential liegt und das elektrisch hohe Potential an die als Innenelektrode dienende Heizschlauchfüllung angelegt ist und bei denen die Zuleitungen für die Zu- und Abfuhr der Heiz-The invention relates to devices for vulcanization, preferably for preheating, of vehicle tires or other objects made of rubber in a high-frequency alternating electric field, in which the tire shape serving as the external electrode is at earth potential and that is electrical high potential is applied to the heating hose filling serving as the inner electrode and where the Supply lines for the supply and discharge of the heating

ίο schlauchfüllung zugleich als elektrische Zuleitungen dienen.ίο hose filling at the same time as electrical supply lines to serve.

Bei derartigen Einrichtungen wird durch den Anschluß an den spannungsführenden Punkt des Hochfrequenzgenerators die Druckflüssigkeit auf ein hohes Potential gegen Erde gebracht. Da die Druckflüssigkeit aber mit dem' gesamten Rohrnetz und dadurch wiederum mit Erde in Verbindung steht, würde ein Kurzschluß des Generators eintreten. In such devices, the connection to the live point of the High-frequency generator brought the hydraulic fluid to a high potential against earth. Since the Hydraulic fluid, however, is in connection with the entire pipe network and thus in turn with the earth stands, the generator would short-circuit.

Die Erfindung hat sich nun die Aufgabe gestellt, geeignete Maßnahmen zur Abriegelung des hohen Potentials der Heizflüssigkeit zu treffen. Zu diesem Zweck sind erfindungsgemäß die Leitungen für die Zu- und Abfuhr der Druckflüssigkeit zur Heizschlauchfüllung oder eine der beiden Leitungen als Drosselspule ausgebildet. Bei einer solchen Ausbildung stellen die Zuleitungen an den Klemmen des Generators einen großen Widerstand gegen Erde dar, der parallel zum Behandlungsobjekt liegt.The invention has now set itself the task of providing suitable measures for locking off the high To meet the potential of the heating fluid. For this purpose, the lines for the Supply and discharge of the hydraulic fluid for the heating hose filling or one of the two lines as Choke coil formed. In such a training place the leads on the terminals of the generator represents a large resistance to earth, which is parallel to the object to be treated.

Die Einrichtung nach der Erfindung ist nicht nur sehr wirksam, sondern auch betriebssicher, da sie keine Absperrorgane oder andere dem Verschleiß unterworfenen Teile und somit keine Wartung erfordert. Die Betriebssicherheit wird darüber hinaus noch dadurch gesteigert, daß keine Handgriffe zur Betätigung notwendig sind. Außerdem können die zu Drosseln verlegten Leitungen unterhalb der Vulkanisiervorrichtung an einer für die Bedienungsperson dieser Vorrichtung nicht zugänglichen Stelle angebracht werden.The device according to the invention is not only very effective, but also reliable because it no shut-off devices or other parts subject to wear and tear and therefore no maintenance required. The operational safety is also increased by the fact that there are no hand movements Actuation are necessary. In addition, the lines laid to chokes can be placed underneath the vulcanizing device be attached to a location inaccessible to the operator of this device.

Die Erfindung ist nicht allein auf Einrichtungen zur Vulkanisation oder Vorwärmung von Fahrzeugluftreifen beschränkt, sie kann vielmehr auch bei sonstigen ringförmigen oder ähnlich gestalteten Körpern aus Gummi oder Gummiaustauschstoffen angewandt werden, bei denen mit einer oder mehreren Außenelektroden und einer Innenelektrode oder Zwischenelektrode gearbeitet werden kann.The invention is not limited to devices for vulcanizing or preheating pneumatic vehicle tires limited, it can rather also with other ring-shaped or similarly shaped Bodies made of rubber or rubber substitutes are used in those with an or several outer electrodes and an inner electrode or intermediate electrode can be worked.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung in schematischer Vereinfachung dargestellt.An exemplary embodiment of the subject matter of the invention is shown in the drawing in a schematic simplification shown.

• Die Reifenform ist mit 1, der Reifenrohling mit 2 und der Heizschlauch mit 3 bezeichnet. Im Heizschlauch 3 befindet sich eine elektrisch leitfähige Flüssigkeitsfüllung 4, die während des Erwärmungs-Vorganges unter Preßdruck steht. Diese Flüssigkeitsfüllung 4 wird durch die Rohre 5 zu- bzw. abgeführt. Die weiterführenden Anschlußleitungen 6 sind durch die Verbindung 7 mit dem spannungsführenden Punkt 8 des Hochfrequenzgenerators 9 elektrisch leitend verbunden. Die Rohre 5 bzw. die Leitungen 6 dienen somit sowohl zum Zu- und Abführen der Druckflüssigkeit als auch als Stromzuführungen zu der als Innenelektrode dienenden elektrisch leitfähigen Flüssigkeitsfüllung 4. In bezug auf die Flüssigkeitsführung finden die Leitungen 6 ihre Fortsetzung in isolierenden Rohrzwischenstücken io, die ihrerseits über zu Drosselspulen 12 gewundene Metalleitungen bei 13 als Vorlauf und bei 14 als Rücklauf an das Rohrnetz angeschlossen sind. Die Reifenform 1 ist durch die Leitung 15 geerdet, ebenso wie durch die Leitung 16 eine leitende Verbindung zwischen der Reifenform ι und dem Erdungspunkt 17 des Generators 9 besteht.• The tire shape is 1, the green tire is 2 and the heating hose is designated by 3. In the heating hose 3 there is an electrically conductive one Liquid filling 4, which during the heating process is under pressure. This liquid filling 4 is supplied or discharged through the tubes 5. The continuing connection lines 6 are through the connection 7 with the live Point 8 of the high frequency generator 9 is electrically connected. The tubes 5 and the Lines 6 thus serve both for supplying and removing the pressure fluid and as power supplies to the electrically conductive liquid filling serving as the inner electrode 4. In With regard to the liquid flow, the lines 6 are continued in insulating pipe spacers io, in turn via metal lines wound into choke coils 12 at 13 as Flow and at 14 as return are connected to the pipe network. The tire shape 1 is through the Line 15 grounded, as well as through line 16 a conductive connection between the tire mold ι and the grounding point 17 of the generator 9 consists.
