Description
Vorrichtung zur Herstellung von Hohlprofilstäben aus härtbaren Kunststoffen, die mittels Glasfasergewebe armiert sind Zur Herstellung von glasfaserarmierten Rohren sind Vorrichtungen bekannt, bei denen Dorne aus metallischen Werkstoffen zur Stützung der die Armierung darstellenden Glasfasergewebe oder-gespinste während des Herstellvorganges verwendet werden.Device for the production of hollow profile rods from hardenable plastics, which are reinforced with glass fiber fabric For the production of glass fiber reinforced Tubes are devices known in which mandrels made of metallic materials to support the glass fiber fabric or fiberglass fabric that represents the reinforcement during of the manufacturing process.
Bei einigen der bekannten Vorrichtungen werden feste Dorne benutzt,
die mit dem getränkten Glasfasermaterial in einen Härteofen gefahren und nach dem
Aushärten des Kunstharzes mühsam aus den aufgeschrumpften fertigen Rohren gezogen
werden. Rohre, die auf diese Weise hergestellt werden, sind durch die Dorne in ihrer
Länge begrenzte Die Einrichtungen zur Herstellung der Rohre bauen sehr hoch durch
mehrere Stockwerke hindurch, besonders, wenn
Nach einem anderen bekannten Verfahren wird ein kurzer beheizter Dorn benutzt, über den das Rohr taktweise gezogen wird. Während ein Teil des Rohres dem Härteprozess unterworfen ist, legt ein Spulensystem Längs-und Querstränge in mehreren Schichten auf und um den Dorn ; nach dem Tränken und Aushärten dieses Teils wird der Rohrstrang um einen Arbeitstakt aus der Härteeinrichtung herausgezogen.Another known method is a short heated mandrel is used, over which the pipe is drawn in cycles. While part of the pipe dem Is subjected to hardening process, a coil system lays longitudinal and transverse strands in several Layers on and around the mandrel; after soaking and hardening this part the pipe string is pulled out of the hardening device by one work cycle.
Auch diese Einrichtung ist durch die Verlegung des Web-bzw. Wickelvorganges in die Rohrfertigungsmaschine apparativ sehr aufwendig. Beim Übergang auf andere Rohrdimensionen entstehen erhebliche Schwierigkeiten, denn es ist erforderlich, alle die Teile, die für die radialen Abmessungen der Rohre bestimmend sind, in komplizierter Weiseauszuwechseln.This facility is also due to the laying of the web or. Winding process very expensive in terms of apparatus in the pipe manufacturing machine. When transitioning to others Pipe dimensions cause considerable difficulties because it is necessary all the parts that are decisive for the radial dimensions of the tubes in more complicated Way to change.
Es ist auch bereits versucht worden, als Armierung fertig gewebte
Glasfaserschläuche zu verwenden. Dabei hat man die in Rohrlängen vorgefertigten
Schläuche auf einen Dorn gebracht, das Gewebe einem Tränkverfahren unterworfen,
die Kunststofftränkung ausgehärtet und sodann schliesslich den Dorn aus dem fertigen
Kunstharzrohr entfernt. Es kennen auf diese Weise nur Rohre beschränkter Längen
erzielt werden, die Rohrwandungen sind nicht blasenfrei,
Eine solche Vorrichtung ist in beispielsweiser Ausführung in der Abbildung dargestellt, wobei die Vorratsrolle oder Haspel, von dem das Glasfasergewebe mit dem innenliegenden Schlauch abläuft mit 1, die Tränkeinrichtung mit 2, die Rollen mit 3, die Quetschwalzenpaare mit 4, die Abstreifer mit 5, die Beschichtungseinrichtung mit 6 die Folienlege-oder Wickeleinrichtung mit 79 die heizbare Härteform mit 8, die Heiz-oder Nachheizeinrichtung mit 9, die Zugeinrichtung mit 10 und der Anschluss für die Druckflüssigkeit oder das Druckgas mit 11 bezeichnet sind.An example of such a device is shown in the figure shown, the supply roll or reel from which the fiberglass fabric with the inner tube runs off with 1, the impregnation device with 2, the rollers with 3, the nip roller pairs with 4, the scrapers with 5, the coating device with 6 the film laying or winding device with 79 the heatable hardening mold with 8, the heating or post-heating device with 9, the pulling device with 10 and the connection are designated by 11 for the pressure fluid or the pressure gas.
Dabei ist es im Interesse einer guten Zugänglichkeit aller Teile vorteilhaft, dass die Einrichtungen, die hinter der Trjnkeinrichtung angeordnet sind, in einer durch die Längsachse des Hohlkörpers hindurchgehenden Ebene teilbar ausgeführt sind.In the interest of easy access to all parts, it is advantageous to that the devices, which are arranged behind the drinking device, in a are designed divisible through the longitudinal axis of the hollow body through plane.
Weiterhin kann man erhebliche Vorteile in bezug auf die Variationsmöglichkeiten des Herstellverfahrens gewinnen, wenn die Beschichtungseinrichtung, die Folienlege-oder -'wickeleinrichtun und die Härteforrn ausfahrbar gestaltet sind" Mit der Vorrichtung gemäss der vorliegenden Neuerung erhält man Rohre von gleichmässiger Wandstärke mit glatten Oberflachen in blasenfreier Qualität.Furthermore, there are considerable advantages with regard to the possible variations of the manufacturing process gain when the coating device, the film laying or -'wickeleinrichtun and the hardness form are designed to be extendable "with the device according to the present innovation, tubes of uniform wall thickness are obtained with smooth surfaces in bubble-free quality.
Als Schlauchmaterial können z. B. Cellulosederivate, Polyvinylchloride, Polyäthylen, Gummi oder luftdicht beschichtet oder imprägnierte Gewebe verwendet werden. Bei der Herstellung von Rohren kreisförmigen Querschnittes mittels der vorgeschlagenen Vorrichtung kann das Glasfaserge. vebe allein durch derartige gespannte Schläuche in Rohrform gehalten werden, besonders, wenn eine vertikale Arbeitsweise gewählt wird. Zur Herstellung von Hohlkörpern, deren Querschnitt von der Kreisform abweicht, ist es vorteilhaft, das getränkte und/oder beschichtete Glasfasergewebe durch den gespannten Schlauch gegen die Innenwandung der Zieh-oder Härtevorrichtung zu drücken.As hose material, for. B. cellulose derivatives, polyvinyl chlorides, Polyethylene, rubber or airtight coated or impregnated fabrics are used will. In the manufacture of pipes of circular cross-section by means of the proposed Device can use the fiberglass. vebe only through such taut hoses be kept in tubular form, especially if a vertical working method is chosen will. For the production of hollow bodies, the cross-section of which deviates from the circular shape, it is advantageous to pass the soaked and / or coated glass fiber fabric through the to press the tensioned hose against the inner wall of the pulling or hardening device.
Auf diese Weise könen auch kompliziert geformte Hohlkörper beliebiger Länge hergestellt werden, Weitere Vorteile der vorgeschlagenen Vorrichtung bestehen darin, dass das Glasfasergewebe im Tränkbad gründlich durchknetet werden kann, ohne dass eine Beschädigung des empfindlichen Gewebes befürchtet werden muss. Hierdurch lassen sich Blaseneinschlüsse, die immer unerwünscht sind, mit Sicherheit vermeiden.In this way, even complex shaped hollow bodies can be of any desired size Length can be produced, there are further advantages of the proposed device in that the glass fiber fabric can be thoroughly kneaded in the soaking bath without that damage to the sensitive tissue must be feared. Through this bubble inclusions, which are always undesirable, can be avoided with certainty.

mm lichter. seite aus Epoxydharz mittels der Vorrichtung
Beispiel 2 Zur Herstellung von armierten Epoxydharzrohrcn, die äusserlich nicht mit Folien beschichtet sind, werden die Folienlegeeinrichtung 7 und die Härteform 8 ausgefahren.Example 2 For the production of reinforced epoxy resin tubes which externally are not coated with films, the film laying device 7 and the hardness form 8 extended.
Der gewebte Glasfaserschlauch mit dem innenliegenden Cellulosehydratschlauch
wandert, wie in Beispiel 1 beschrieben, durch die Tränkeinrichtung und wird dann
durch den Abstreifer 5, die Beschichtungseinrichtung 6 und den Härteofen 9 gezogen.
Die Beschichtungseinrichtung 6 enthält eine thixotrope Epoxydharzpaste. Sie bewirkt
eine
Beispiel 3 Glasfaserarmierte Polyesterharzrohre von beispielsweise 30 mm lichter Weite werden in einfachster Weise nach Ausfahren der Beschichtungseinrichtung 6 und der Folienlegeeinrichtung 7 hergestellt.Example 3 Glass fiber reinforced polyester resin pipes from for example A clear width of 30 mm is achieved in the simplest way after the coating device has been extended 6 and the film laying device 7 produced.
Der Glasfaserschlauch mit dem innenliegenden Cellulosehydratschlauch durchläuft nach dem Tränkbad lediglich die Abstreifvorrichtung 5, die Härteform 8 und den Nachhärteofen 9. Die Zieheinrichtung 10 bewegt sich taktkontinuierlich in der Weise, dass sie in einer halben Minute etwa 20 cm voranschreitet, um dann etwa 1 1/2 Minute stehen zu bleiben und hierauf wieder in 1/2'minute 20 cm weiterzulaufen. Auf diese weise verlassen Rohre von besonders glatter Oberfläche die innen glanzpolierte, et. va 60 cm lange Härteform, Die angeführten Beispiele begrenzen die Möglichkeiten der vorgeschlagenen Vorrichtung zur Herstellung von Hohlkörpern in keiner Weise. Sie zeigen lediglich einige Varianten der Einrichtung gemäss der Erfindung. Auch die genannten Rohrdimensionen bedeuten keine Begrenzungen. Die Vorrichtung gemäss der Neuerung kann zur Herstellung von Rohren aller Rohrkörperdimenslonen verwendet werden, die für Kunstharzrohre handelsüblich sind und kann darüber hinaus auch zur Herstellung von solchen Hohlprofilstäben, die von der Kreisrohrform stark abweichen, eingesetzt werden.The fiberglass hose with the inner cellulose hydrate hose only runs through after the soaking bath the stripping device 5, the hardening mold 8 and the post-hardening furnace 9. The drawing device 10 moves continuously in such a way that it advances about 8 inches in half a minute, to then to stand for about 1 1/2 minute and then to continue walking for 1/2 minute 20 cm. In this way, tubes with a particularly smooth surface leave the internally polished, et. Mainly 60 cm long hardness form, the examples given limit the possibilities the proposed device for the production of hollow bodies in no way. They only show a few variants of the device according to the invention. Even the pipe dimensions mentioned do not mean any limitations. The device according to The innovation can be used to manufacture pipes of all pipe body dimensions that are commercially available for synthetic resin pipes and can also be used for Manufacture of such hollow profile rods that differ greatly from the circular tube shape, can be used.
