Description
Hohler Wickeldorn Die Erfindung bezieht sich auf einen hohlen Wickeldorn zum Herstellen von gewickelten Behältern, Rohren oder ähnlichen Hohlkörpern, der aus mehreren Segmenten#besteht, von denen ein schmales Segment zur Verringerung des Umfangs des Wickeldornes einziehbar ist. Hollow winding mandrel The invention relates to a hollow winding mandrel for the production of wound containers, pipes or similar hollow bodies, the consists of several segments #, one of which is a narrow segment for reduction the circumference of the mandrel is retractable.
Es ist allgemein bekannt, Hohlkörper dadurch-herzustellen, daß eine mit Glasfasern verstärkte Kunststoffschicht (G F K3 auf einen Wickeldorn aufgetragen wird. In-der Regel ist der Wickeldorn, dessen Oberfläche den Innenkonturen des herzustellenden Teiles, z. B. eines Batterie- oder Koffertanks entspricht, auf einer Welle angeordnet, welche mit einem Ende fest in einem Antriebsbock gelagert ist, während das freie Ende auf einem verfahrbaren Rollenlager aufsitzt, Nach dem Auftragen und Aushärten des verstärkten Kunststoffes wird das verfahrbare RoLlenlager entfernt und der entstandene Behälterschuß in axialer Richtung vom Wickeldorn abgezogen.It is generally known to produce hollow bodies in that a Plastic layer reinforced with glass fibers (G F K3 applied to a winding mandrel will. As a rule, the winding mandrel has a surface that matches the inner contours of the one to be produced Part, e.g. B. corresponds to a battery or suitcase tank, arranged on a shaft, which is firmly mounted at one end in a drive bracket, while the free one End rests on a movable roller bearing, after application and hardening of the reinforced plastic, the movable roller bearing is removed and the resulting one Part of the container withdrawn from the winding mandrel in the axial direction.
Da die Glasfasern mit erheblicher Vorspannung aufgewickelt werden und zudem beim Aushärten des Harzes eine Schrumpfung auftritt, sitzt der Schuß mit starker Spannung auf dem Wickeldorn. Aus diesem Grund ist .es notwendig, den hohlen Wickeldorn aus stabilem Material und in einer biegesteifen Konstruktion herzustellen.Because the glass fibers are wound up with considerable pre-tension and shrinkage also occurs when the resin hardens, the shot sits with it strong tension on the winding mandrel. For this reason it is necessary to use the hollow Manufacture winding mandrel from stable material and in a rigid construction.
Infolge der recht starren Konstruktion des Wickeldornes und der starken Spannung, mit der der Schuß auf dem Üorn #aufsitzt, ist es fast unmöglich, den Schuß von einem einteiligen Wickeldorn abzuziehen. Es wurde deshalb vorgeschlagen, einen Wickeldorn aus mehreren Segmenten auszubilden. Zwei dieser Segmente sollten jeweils fast die Hälfte des äußeren Mantels umfassen und gelenkig miteinander verbunden sein. Der verbleibende Spalt sollte durch ein schmaleres Segment verschlossen werden, welches nach dem Wickeln und Aushärten mittels Zylinder und Kolbenstange in radialer Richtung hydraulisch eingezogen werden konnte. Da die breiteren Segmente nach dem Einziehen des schmaleren Segmentes etwas nach innen klappen können, war infolge der geschilderten Gestaltung des Wickeldornes das Abziehen des Schusses vom Dorn möglich.As a result of the rather rigid construction of the winding mandrel and the strong one Tension with which the shot rests on the urn, it is almost impossible to get the shot from a one-piece winding mandrel. It was therefore suggested that one Winding mandrel off to train several segments. Two of these segments should each encompass almost half of the outer mantle and articulate to one another be connected. The remaining gap should be closed by a narrower segment which after winding and hardening by means of a cylinder and piston rod could be drawn in hydraulically in the radial direction. Because the wider segments being able to fold inwards a little after pulling in the narrower segment, was as a result of the described design of the winding mandrel, the pulling off of the weft from the mandrel possible.
Ein Nachteil dieser Ausbildung besteht jedoch darin, daß recht große Kräfte aufzuwenden sind, um das schmale Segment in radialer Richtung einzuziehen. Wegen der starken Spannung des verstärkten Kunstharzes werden nämlich die Segmente recht kräftig gegeneinander gepreßt. Außerdem ist bei der Bewegung senkrecht zum Schuß eine gewisse Haftung zu überwinden. Damit das schmale Segment gleichmäßig eingezogen werden kann sind zudem auf jeden Fall mehrere Hydraulikpumpen erforderlich.A disadvantage of this training, however, is that it is quite large Forces have to be used to pull in the narrow segment in the radial direction. Namely, because of the strong tension of the reinforced synthetic resin, the segments pressed against each other quite forcefully. In addition, when moving is perpendicular to the Shot to overcome a certain liability. So that the narrow segment is even In addition, several hydraulic pumps are required in any case.
Der geschilderte Nachteil wird erfindungsgemäß dadurch behoben, daß das schmale Segment durch Streben beweglich mit der Welle verbunden und durch Krafteinwirkung in axialer Richtung ausschwenkbar ist. Die benötigten Kräfte zur Entfernung des schmalen Segmentes sind weit niedriger als bei der älteren Methode des Einziehens in radialer Richtung, da jetzt das schmale Segment gleitend vom Schuß gelöst wird. Es reicht somit eine einzige Kraftquelle aus.The disadvantage described is eliminated according to the invention in that the narrow segment is movably connected to the shaft by struts and by the action of force can be swiveled out in the axial direction. The forces required to remove the narrow segment are far lower than the older method of pulling in in the radial direction, since now the narrow segment is released from the shot in a sliding manner. A single source of power is therefore sufficient.
Die bewegliche Verbindung des schmalen Segmentes mit der Welle bewirkt, daß dieses bei einer Bewegung in axialer Richtung gleichzeitig nach innen geschwenkt wird. Es ist also nur eine kurze Bewegung notwendig, um den Umfang des Wickeldornes zu verringern. Damit dieses Einschwenken möglich ist, muß darauf geachtet werden, daß sich das schmale Segment nach innen und in Schwenkrichtung konisch erweitert.The flexible connection of the narrow segment with the shaft causes that this is pivoted inward at the same time when moving in the axial direction will. So only a short movement is necessary around the circumference of the winding mandrel to reduce. So that this pivoting is possible, it must be respected that the narrow segment widens conically inwards and in the pivoting direction.
Das Verschwenken des schmalen Segmentes erfolgt zweckmäßigerweise durch eine Hydraulikpumpe, die an einer der Streben angreift.The narrow segment is expediently pivoted by a hydraulic pump that engages one of the struts.
Die beigefügte Zeic#inung stellt ein Anführungsbeispiei der Neuerung dar.The attached drawing provides an example of the innovation represent.
Es zeigen: Fig. 1: Einen Längsschnitt durch den geschlossenen Wickeldorn Fig. 2:- Eine Stirnansicht des Wickeldornes nach Fig. 1, Fig. 3: Einen Längsschnitt durch den Wickeldorn mit ausgeschwenktem Segment, Fig. 4: Eine Stirnansicht des Wickeldornes nach Fig. 3, Fig. 5: Eine Draufsicht auf den Wickeldorn nach Fig. 1 und Fig. 6: Das vergrößerte Detail x aus Fig. 2.They show: FIG. 1: A longitudinal section through the closed winding mandrel Fig. 2: - A front view of the winding mandrel according to Fig. 1, Fig. 3: A longitudinal section through the winding mandrel with the segment swung out, FIG. 4: An end view of the Winding mandrel according to FIG. 3, FIG. 5: A top view of the winding mandrel according to FIG. 1 and FIG. 6: The enlarged detail x from FIG. 2.
Auf der Welle 1, die mit einem Ende 2 fest mit einer Antriebswelle 3 verbunden und mit dem anderen Ende 4 auf einem nicht dargestellten verfahrbaren Rollenlager aufsitzt, ist über Streben 5,6 der hohle Wickeldorn gelagert. Dieser besteht bei der dargestellten Ausführung für einen Batterie tank aus zwei größeren Seitensegmenten 7, welche in Gelenken 8 mit einem Grundsegment 9 Verbunden sind und einem schmalen Segment 10. Eine andere Aufteilung ist je nach dem zu wickelnden Körper möglich.On the shaft 1, with one end 2 fixed to a drive shaft 3 connected and with the other end 4 on a movable, not shown The roller bearing is seated, the hollow winding mandrel is mounted on struts 5, 6. This consists in the version shown for a battery tank of two larger ones Side segments 7 which are connected to a base segment 9 in joints 8 and a narrow segment 10. Another division depends on the one to be wound Body possible.
Das. schmale Segment 10 ist durch die Streben 6 über Gelenke 11 mit der Welle 1 verbunden. An einer der Streben 6 greift ein Hydraulikzylinder 12 an, der nur schematisch angedeutet ist.That. narrow segment 10 is through the struts 6 via joints 11 with connected to shaft 1. A hydraulic cylinder 12 engages one of the struts 6, which is only indicated schematically.
Nach dem Wickeln und Aushärten reicht ein geringer Druck der -Pumpe aus, um das Segment 10 in axialer und radialer Richtung auszuschwenken. Die Seitensegmente 7 können etwas nach innen klappen, wodurch das leichte Abziehen des Schusses ermöglich wird.After winding and hardening, a slight pressure from the pump is sufficient from to pivot the segment 10 in the axial and radial directions. The side segments 7 can do something inside fold, making it easy to pull off the shot is made possible.
Damit das Segment 10 ausschwenken kann, ist es so zu gestalten, daß es sich in Schwenkrichtung und nach innen konisch erweitert (Fig. 5 + Fig. 6). Die Blechwinkel 13 verhindern eine zu starke Abnutzung der Stoßstellen.So that the segment 10 can swing out, it is to be designed so that it widens conically in the pivoting direction and inwards (Fig. 5 + Fig. 6). the Sheet metal angles 13 prevent excessive wear of the joints.
Der erfindungsgemäße Wickeldorn ist besonders vorteilhaft in Verbindung mit einer freitragenden Welle anzuwenden, da nur wenig Bauteile mit verhältnismäßig geringem Gewicht benötigt werden.The winding mandrel according to the invention is particularly advantageous in combination to be used with a cantilevered shaft, as there are only a few components with relatively low weight are required.
