Abstract
Description
Die Erfindung betrifft ein Verfahren zum Herstellen bombierter, vulkanisierter, schlauchförmiger Erzeugnisse gemäß dem Oberbegriff des Anspruches 1 sowie eine Vorrichtung zur Durchführung des Verfahrens. Solche Verfahren dienen insbesondere zur Herstellung von Luftfedern im Kraftfahrzeugbereich.The The invention relates to a method for producing cambered, vulcanized, tubular products according to the generic term of claim 1 and an apparatus for carrying out the method. Such methods are used in particular for the production of air springs in the automotive field.
Auf herkömmliche Art und Weise wurden bislang Schlauchzuschnitte von oben nach unten auf eine feste Innenform aufgezogen und mit einer Heizmanschette umgeben, bis die gewünschte Form dauerhaft erhalten wurde. Alternativ wurde ein Schlauchzuschnitt von innen nach außen über einen Heizschlauch gegen eine feste Form gedrückt, bis die gewünschte Form erzielt wurde. Diese Verfahren sind sehr aufwändig und benötigen einen großen apparativen Aufwand.On conventional Way were previously hose blanks from top to bottom mounted on a solid inner mold and with a heating jacket surrounded until the desired Form was obtained permanently. Alternatively, a hose blank from the inside out over one Air hose pressed against a solid mold until the desired shape was achieved. These procedures are very complicated and require one huge equipment expense.
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren und eine Vorrichtung bereitzustellen, mit denen prozesssicher Schlauchzuschnitte bombiert und vulkanisiert werden können.task It is the object of the present invention to provide a method and an apparatus provide, with which process-safe hose blanks cambered and can be vulcanized.
Erfindungsgemäß wird diese Aufgabe durch ein Verfahren mit den Merkmalen des Anspruchs 1 sowie durch eine Vorrichtung mit den Merkmalen des Anspruches 8 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen aufgeführt.According to the invention this Task by a method having the features of claim 1 and solved by a device having the features of claim 8. advantageous Embodiments and developments of the invention are listed in the subclaims.
Durch die unmittelbare Einleitung eines erhitzten Fluides in den Schlauchzuschnitt und das Pressen des Schlauchzuschnittes von innen gegen eine Vulkanisationsform wird mit geringem apparativen Aufwand erreicht, dass der Schlauchzuschnitt die gewünschte Form annimmt. Weiterhin kann durch das Fluid die benötigte Wärme zur dauerhaften Formung des Schlauchzuschnittes bereitgestellt werden, ohne dass aufwändige Heizmanschetten oder Heizschläuche angelegt oder eingelegt werden müssten.By the direct introduction of a heated fluid into the tube blank and pressing the tube blank from the inside against a vulcanization mold is achieved with little equipment, that the hose blank the desired Takes shape. Furthermore, the heat required by the fluid for permanent shaping of the hose blank, without that elaborate Heating sleeves or heating hoses would have to be created or inserted.
Vorteilhafterweise wird das Fluid erhitzt und dann in den Schlauchzuschnitt eingeleitet, da dieses leicht und schnell eingeleitet und abgelassen werden kann, was die Prozeßführung erleichtert.advantageously, the fluid is heated and then introduced into the hose blank, since this can be easily and quickly introduced and discharged what makes the process easier.
Eine einfache Fixierung des Schlauchzuschnittes in der Vulkanisationsform erfolgt vorteilhafterweise dadurch, dass der Schlauchzuschnitt in die Vulkanisationsform eingeführt und an beiden Enden abgedichtet wird. Durch diese Abdichtung, die beispielsweise durch Einführen zweier Endstopfen stattfindet, wird der Schlauchzuschnitt an Teilen der Wandung der Vulkanisationsformen festgeklemmt und durch einfaches Einleiten des Fluides durch die Abflussstopfen kann durch Aufblähen und gleichzeitigens Aufeinanderzubewegen der beiden Vulkanisationsformen ein Anlegen des Schlauchzuschnittes an die Innenseite der Vulkanisationsform bewirkt werden.A easy fixation of the tube blank in the vulcanization mold takes place advantageously in that the hose blank in introduced the vulcanization mold and sealed at both ends. Through this seal, the for example by insertion two end plugs takes place, the hose blank is divided into parts clamped the wall of the vulcanization molds and by simple Injection of the fluid through the drain plugs can be caused by inflation and simultaneous movement of the two vulcanization forms applying the tube blank to the inside of the vulcanization mold be effected.
Zum Einklemmen der Schlauchzuschnitte ist es vorgesehen, dass die Vulkanisationsform geteilt ausgebildet ist und entlang der Längserstreckung des Schlauchzuschnittes in Richtung auf die Endstopfen verfahren wird. Gleichzeitig wird dadurch der Schlauchzuschnitt ggf. gelängt bzw. die korrekte Länge des in der Vulkanisationsform enthaltenen Schlauchzuschnittes wird eingestellt und anschließend werden die Vulkanisationsformhälften wieder aufeinander zu verfahren, um die Vulkansisationsform zu verschließen.To the Clamping the hose blanks, it is provided that the vulcanization mold is formed divided and along the longitudinal extent of the hose blank is moved in the direction of the end plug. At the same time as a result, the hose blank may lengthen or the correct length of the in the vulcanization mold contained hose blank is set and subsequently become the vulcanization mold halves to move towards each other again to close the volcanic form.
Das Schließen der Vulkanisationsform erfolgt während des Aufbringens des Bombierungsdruckes, und der Bombierungsdruck wird nach dem Schließen der Vulkanisationsform auf Vulkanisationsdruckniveau erhöht. Durch das Aufbringen des Bombierungsdruckes wird verhindert, dass der Schlauchzuschnitt in sich zusammenfallt. Der Vulkanisationsdruck wird solange aufrechterhalten, bis der Schlauchzuschnitt die gewünschte Form erhalten und den gewünschten Vulkanisationsgrad erreicht hat. Anschließend werden der Druck abgelassen, die Endstopfen entfernt und die Vulkanisationsform geöffnet, so dass das fertig vulkanisierte Bauteil aus der Form entnommen werden kann.The Shut down the vulcanization mold takes place during the application of the crowning pressure, and the crowning pressure will after closing the vulcanization mold increased to Vulkanisationsdruckniveau. By the application of the crown pressure prevents the hose blank collapses. The vulcanization pressure is maintained as long as until the hose blank get the desired shape and the desired Vulkanisationsgrad has reached. Then the pressure is released the end plugs are removed and the vulcanization mold opened so that the finished vulcanized component be removed from the mold can.
Die Vorrichtung zur Durchführung des oben beschriebenen Verfahrens sieht vor, dass die Vulkanisationsform senkrecht zur Längserstreckung des zu vulkanisierenden Schlauchzuschnittes geteilt ist, damit einerseits eine Anpassung an die zu vulkanisierende Schlauchlänge und andererseits ein leichtes Entfernen des fertig vulkanisierten Schlauchzuschnittes erfolgen kann. Zwei Endstopfen sind in die Vulkanisationsform einführbar und legen den Schlauchzuschnitt in der Vulkanisationsform fest, wobei ein Endstopfen dergestalt ausgebildet ist, dass ein Fluid, vorzugsweise Heißdampf, in den Schlauchzuschnitt einleitbar ist. Ebenso kann das entstehende Kondensatwasser durch einen Endstopfen abgeführt werden.The Apparatus for carrying out of the above-described method provides that the vulcanization mold perpendicular to the longitudinal extent divided to be vulcanized hose blank, so on the one hand an adaptation to the hose length to be vulcanized and on the other hand, easy removal of the finished vulcanized hose blank can be done. Two end plugs are insertable into the vulcanization mold and determine the hose blank in the vulcanization mold, wherein an end plug is formed such that a fluid, preferably Hot steam, can be introduced into the hose blank. Likewise, the resulting condensation water be discharged through an end plug.
