Abstract
Description
Die Erfindung betrifft ein Verfahren zum Herstellen des Rahmens für Roller- Scates oder dergleichen.The invention relates to a method for producing the frame for scooter Scates or the like.
Zum Herstellen von rohrförmigen Bauteilen, wie sie für Golfschläger und an dere Schläger benötigt werden, ist es bekannt, Graphit- und Glasfasern zu verwen den. Dabei haben diese rohrförmigen Bauteile keine Löcher oder Öffnungen. So läßt sich in das rohrförmige Bauteil Druckluft einblasen und damit ein Innendruck auf das Rohr ausüben, das außerdem einem Heißpreßvorgang unterworfen wird. Der Rahmen für Roller-Scates läßt sich aber nicht aus rohrförmigen Bauteilen herstellen und benötigt Ausnehmungen bzw. Öffnungen, was dazu geführt hat, daß Verbund werkstoffe zum Herstellen solcher Rahmen bisher keine Verwendung finden konn ten. Normalerweise sind Skate-Rahmen aus einer Aluminiumlegierung oder Kunst stoff hergestellt.For the manufacture of tubular components such as those for golf clubs and whose rackets are needed, it is known to use graphite and glass fibers the. These tubular components have no holes or openings. So lets blow compressed air into the tubular component and thus an internal pressure exercise the tube, which is also subjected to a hot pressing operation. Of the Frame for roller scates can not be made from tubular components and requires recesses or openings, which has led to the fact that composite materials for the manufacture of such frames have so far not been used Usually, skate frames are made of aluminum alloy or art fabric made.
Die Erfindung zielt darauf ab, vorgenannte Nachteile bei der Herstellung von Skate-Rahmen zu vermeiden. So liegt der Erfindung hauptsächlich die Aufgabe zu grunde, ein Verfahren anzugeben, mit dem ein Skate-Rahmen aus Verbundwerk stoff herstellbar ist. The invention aims at the aforementioned disadvantages in the manufacture of Avoid skate frames. So the invention is mainly the task reasons to specify a method by which a skate frame made of composite fabric can be produced.
Erfindungsgemäß ist diese Aufgabe mit den Merkmalen des Patentanspruchs l gelöst. So besteht das Verfahren darin, daß man ein Formstück herstellt, dessen Ge stalt der des Rahmens entspricht, daß man mehrere Schichten von mit Kunststoff getränkten Fasern vorbereitet und ablängt und diese Verbundwerkstoff-Fasern auf das Formstück aufbringt, und die Fasern dabei in die Form des Rahmens bringt, worauf man eine Form benutzt, deren Formhohlraum das Formstück und die ge tränkten Fasern aufnimmt, worauf die Form und die Fasern einem Heißpreßvorgang unterworfen werden, um so die Fasern auszuhärten und damit den Rahmen zu for men.According to the invention, this object is achieved with the features of patent claim 1 solved. So the method is that one produces a fitting, the Ge stalt corresponds to that of the frame that one has several layers of with plastic soaked fibers prepared and cut to length and these composite fibers on applies the fitting and thereby brings the fibers into the shape of the frame, whereupon one uses a mold, the mold cavity of which the fitting and the ge soaked fibers, whereupon the shape and the fibers are hot-pressed be subjected so as to harden the fibers and thus to form the frame men.
Das Formstück besitzt einen abgeschrägten Teil und die Form ist ebenfalls mit einem abgeschrägten Flansch versehen, der den abgeschrägten Teil des Formstücks derart erfaßt, daß es im Formhohlraum der Form sicher gehalten wird.The fitting has a bevelled part and the shape is also with provided with a chamfered flange which is the chamfered part of the fitting detected such that it is held securely in the mold cavity of the mold.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfol genden Beschreibung, in der ein Ausführungsbeispiel anhand der Zeichnung erläu tert ist. Es zeigen:Further features and advantages of the invention result from the following ing description, in which an exemplary embodiment is explained with reference to the drawing is tert. Show it:
Fig. 1 eine perspektivische Ansicht eines Skate-Rahmens, der mit dem erfin dungsgemäßen Verfahren hergestellt werden soll; Figure 1 is a perspective view of a skate frame, which is to be produced with the inventive method.
Fig. 2 eine auseinandergezogene Ansicht einer Form; Figure 2 is an exploded view of a mold.
Fig. 3 einen Schnitt durch die Form und Fig. 3 shows a section through the shape and
Fig. 4, 5 und 6 Schnitte unterschiedlicher Ausführungen der Form. Fig. 4, 5 and 6 are sectional views of different embodiments of the mold.
Zunächst wird anhand der Fig. 1 bis 3 das erfindungsgemäße Verfahren zum Herstellen eines Rahmens für einen Rollschuh o. ä. aus Verbundwerkstoff in einem Heißpressprozeß erläutert. Aus den Fig. 2 und 3 geht hervor, daß eine Form 4 zum Ausführen des Verfahrens benutzt wird. Die Form 4 besteht aus einer unteren Formhälfte 42 und einer oberen Formhälfte 41, wobei jede Formhälfte mit einem Formhohlraum 410 versehen ist, in den ein Formstück 2 eingesetzt wird. Mehrere Schichten von mit Kunststoff 3 getränkten Fasern (Fig. 3) werden abgeschnitten und auf die Außenseite des Formstücks 2 aufgelegt, wobei das Formstück 2 der Gestalt des Rahmens 1 entspricht. Die Form 4 und die Fasern 3 des Verbundwerkstoffes werden dann einem Heißpressvorgang unterworfen, um den Kunststoff mit den Fa sern 3 des Verbundwerkstoffes auszuhärten und den Rahmen 1 zu bilden, nachdem die Fasern 3 abgekühlt sind.First, the method according to the invention for producing a frame for a roller skate or the like from composite material in a hot press process is explained with reference to FIGS. 1 to 3. From FIGS. 2 and 3 that a mold 4 is used for performing the method is apparent. The mold 4 consists of a lower mold half 42 and an upper mold half 41 , each mold half being provided with a mold cavity 410 into which a molded piece 2 is inserted. Several layers of fibers impregnated with plastic 3 ( FIG. 3) are cut off and placed on the outside of the molding 2 , the molding 2 corresponding to the shape of the frame 1 . The mold 4 and the fibers 3 of the composite are then subjected to a hot pressing process in order to harden the plastic with the fibers 3 of the composite and to form the frame 1 after the fibers 3 have cooled.
Wie die Fig. 2 und 3 am besten zeigen, hat das Formstück 2 vorzugsweise einen abgeschrägten Teil 21, der an einem abgeschrägten Flansch 411 der oberen Formhälfte 41 anstößt, damit so das Formstück 2 sicher in den Formhohlräumen 410 der Formhälften 41 und 42 gehalten wird.As best shown in FIGS. 2 and 3, the molded part 2 preferably has a beveled part 21 which abuts a beveled flange 411 of the upper mold half 41 so that the molded part 2 is held securely in the mold cavities 410 of the mold halves 41 and 42 .
In einer abgeänderten Ausführungsform gemäß Fig. 4 kann das Formstück 5 großenteils im Formhohlraum der oberen Formhälfte 51 einsitzen und liegt nur zum geringen Teil in der unteren Formhälfte 52. Gemäß Fig. 5 kann das Formstück 70 auch fest an der unteren Formhälfte 7 angeordnet sein und sitzt im Formhohlraum der oberen Formhälfte 71. Fig. 4 zeigt ein Formstück 60, das in den Formhohlräu men zweier seitlicher Formhälften 61 und 62 sitzt.In a modified embodiment according to FIG. 4, the molded part 5 can largely sit in the mold cavity of the upper mold half 51 and is only partially in the lower mold half 52 . Referring to FIG. 5, the fitting 70 can also be arranged fixedly on the lower mold half 7 and is located in the mold cavity of the upper mold half 71. Fig. 4 shows a shaped piece 60 , which sits in the Formhohlräu men two side mold halves 61 and 62 .
