Abstract

The mandrel surface consists of a number of arc-shaped components supported by tubular spokes radiating tangentially from its shaft. The arc components are enveloped with a sheet metal cylinder. A surface segment, extending along the full length of the mandrel, hinges inwards, and hydraulically operating levers titl this segment inwards, thus reducing the mandrel circumference and enabling wound cylinders to be extracted. The device permits cylinders of >=2m dia. to be wound.

Description

Maschine zum Wickeln von zylindrischen Körpern Die Erfindung betrifft eine Maschine zum Wickeln von zylindrischen Körpern vorzugsweise aus glasfaserverstärktem Kunststoff. Machine for winding cylindrical bodies The invention relates to a machine for winding cylindrical bodies, preferably made of glass fiber reinforced Plastic.

Nach der üblichen Herstellungsweise von zylindrischen Körpern aus glasfaserverstärktem Kunststoff werden die mit Kunststoff getränkten Glasfasern über einen sich drehenden Hohldorn gewickelt. Nach dem Erhärten wird der Hohldorn in seinem Durchmesser etwas verringert, z'B. durch Einklappen eines Segmentes, damit der gewickelte Körper vom Hohldorn abgezogen werden kann. Wenn Rohre mit größerem Durchmesser auf diese Weise hergestellt werden sollen, treten bei den bekannten Konstruktionen bestimmte Nachteile auf. Entweder ist der Hohldorn zu schwer und kann deshalb nicht mehr freitragend gelagert werden oder zu leicht aber nicht mehr stabil genug, um die großen Schrumpfkräfte aufnehmen zu können.In the usual way of manufacturing cylindrical bodies The glass fibers soaked with plastic are made of glass fiber reinforced plastic wound over a rotating hollow mandrel. After hardening, the hollow mandrel becomes slightly reduced in diameter, e.g. by folding in a segment, so the wound body can be pulled off the hollow mandrel. When pipes with larger Diameters to be made in this way occur with the known Constructions have certain disadvantages. Either the hollow mandrel is too heavy and can therefore no longer be stored unsupported or too light but no longer stable enough to be able to absorb the large shrinkage forces.

Der Versuch, evtl. Unstabilitäten und Beulen durch eine, um die Blech-Außenhaut gelegte zusätzliche Gummihaut auszugleichen erschwert das Abziehen der fertigen Zylinder wegen des hohen Reibfaktors.Trying to remove any instabilities and dents through a to the sheet metal outer skin Compensating for the additional rubber skin that has been laid makes it difficult to pull off the finished Cylinder because of the high friction factor.

Der Erfindung liegt die Aufgabe zugrunde, eine Maschine zum Wickeln von zylindrischen Körpern aus glasfaserverstäitem Kunststoff zu schaffen, mit der es möglich ist, ohne Schwierigkeiten auch Rohre mit größerem Durchmesser, z.t3. mit einem Durchmesser von 2 m und darüber herzustellen.The invention is based on the object of a machine for winding to create cylindrical bodies made of glass fiber reinforced plastic, with the It is possible to use pipes with a larger diameter, e.g. 3. with a diameter of 2 m and more.

Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, den mit einem einklappbaren Segment versehenen Hohldorn aus zylindrisch gebogenen U-Profileisen aufzubauen, die von tangential auf der zentralen Antriebswelle angeordneten Rohrspeichen getragen werden und mit einer Blechhaut überzogen sind.To solve this problem, the invention proposes the Hollow mandrel made of cylindrically bent U-profile iron with a collapsible segment build up the tubular spokes arranged tangentially on the central drive shaft are worn and covered with a sheet metal skin.

Auf diese Weise kann auf Gelenkpunkte im Mantel des Hohldornes verzichtet werden, denn die tangentiale Anordnung der tragenden Rohrspeichen begünstigt beim Einklappen des Segmentes das Zusammenziehen des Mantels auf geringeren Durchmesser.In this way, articulation points in the jacket of the hollow mandrel can be dispensed with because the tangential arrangement of the load-bearing tubular spokes favors the Collapsing the segment contraction of the jacket to a smaller diameter.

Einerseits weist wegen der fehlenden Gelenkpunkte der Hohldorn trotz der Leichtbauweise eine große StabilIta#t auf und andererseits ist er bei eingeklapptem Segment doch so nachgiebig, daß mit geringem Kraftaufwand die Durchmesserverkleinerung ermöglicht wird. Die fliegende Lagerung des Hohldornes selbst bei großen Abmessungen der zu wickelnden Körper wird durch die neue Konstruktion ermöglicht.On the one hand, the hollow mandrel shows despite the lack of articulation points the lightweight construction a great stability and on the other hand it is when folded The segment is so flexible that the diameter can be reduced with little effort is made possible. The floating mounting of the hollow mandrel even with large dimensions the body to be wrapped is made possible by the new construction.

In der Zeichnung ist ein AusfUhrungsbeispiel dargestellt.An exemplary embodiment is shown in the drawing.

Es zeigen: Fig. 1 den Prinzipaufbau der Maschine, Fig. 2 einen Schnitt quer durch den Hohldorn, Fig. 5 das einklappbare Segment in vergrößertem Maßstab.They show: FIG. 1 the basic structure of the machine, FIG. 2 a section across the hollow mandrel, FIG. 5 shows the collapsible segment on an enlarged scale.

Der Hohldorn 1 besteht aus zylindrisch gebogenen U-Profileisen 2, die von tangential auf der zentrischen Antriebswelle 5 angeordneterl Rohrspeichen 4 getragen werden. Die U-Profileisen sind von einem Blechmantel 5 umfaßt. Um den Durchmesser des Blechmantel 5 verkleinern zu können, besitzt dieser ein nach innen einklappbares, sich über die Länge des Hohldornes erstreckendes Segment 6. Dieses Segment ist an einem Ende gelenkig am Mantel 5 des Hohldorns 1 befestigt, und an dem anderen Ende greift eine vorzugsweise hydraulisch betätigte Zugstange 7 über einen Arm 8 an, die Gelenkpunkte 9 aufweist, von welchen Je ein witerer gelenkig gelagerter Arm 10 und 11 zu den, an das Segment 6 angrenzenden Enden des Mantels 5 führt.The hollow mandrel 1 consists of cylindrically bent U-profile iron 2, the tubular spokes arranged tangentially on the central drive shaft 5 4 are worn. The U-profile irons have a sheet metal jacket 5 includes. In order to be able to reduce the diameter of the sheet metal jacket 5, it has a segment that can be folded inwards and extends over the length of the hollow mandrel 6. This segment is hinged at one end to the jacket 5 of the hollow mandrel 1, and a preferably hydraulically operated pull rod engages at the other end 7 via an arm 8, which has points of articulation 9, each of which is articulated by a different one supported arm 10 and 11 to the ends of the jacket adjoining segment 6 5 leads.

Wird die Zugstange 7 nach innen bewegt, dann klappt das Segment 6 nach innen und gleichzeitig wird durch die Arme 10 und 11 eine Umfangverkleinerung des Mantels 5 erreicht. Wegen der tangential angeordneten Rohrspeichen 4 ist dies ohne großen Kraftaufwand mdglich.If the pull rod 7 is moved inwards, the segment 6 folds inward and at the same time by the arms 10 and 11 a reduction in circumference of the jacket 5 reached. Because of the tangentially arranged tubular spokes 4, this is possible without great effort.

Der Hohldorn 1 dieser Konstruktion kann fest- in dem Antriebsbock 12 einseitig gelagert sein, während das andere Ende der Welle 5 lediglich auf einem verfahrbaren Rollenlager aufsitzt. Nach Fertigstellung des gewickelten Körpers kann der Umfang des Hohldornes auf die geschilderte Weise verkleinert werden, anschließend wird das verfahrbare Rollenlager entfernt und der gewickelte Körper von dem Blechmantel abgezogen.The hollow mandrel 1 of this construction can be fixed in the drive bracket 12 be mounted on one side, while the other end of the shaft 5 only on one movable roller bearing is seated. After completing the wrapped body, you can the circumference of the hollow mandrel can be reduced in the manner described, then the movable roller bearing is removed and the wound body from the sheet metal jacket deducted.
