Um in einfacher Weise eine/n reproduzierbare/n hochgenaue/n Kontur und Querschnitt am Verbundbauteil bei gleichzeitiger Verringerung der Taktzeit im Herstellungsprozess zu ermöglichen, wird vorgeschlagen, dass das Hohlprofil (5) während seiner Aufweitung, bei der am Hohlprofil (5) ein Ausbauchbereich (10) ausgeformt wird, im Ausbauchbereich (10) umspritzt wird.The invention relates to a method for producing a composite component, wherein a hollow profile (5) is expanded by means of fluidic internal high pressure into a final shape and wherein the hollow profile (5) is encapsulated with injection molding material to form an injection molding element (12). In order to easily enable a reproducible / highly precise contour and cross section on the composite component while simultaneously reducing the cycle time in the production process, it is proposed that the hollow profile (5) has a bulging area during its widening, while the hollow profile (5) (10) is molded, in the bulge region (10) is overmolded.
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Verbundbauteils gemäß dem Oberbegriff des Patentanspruches 1.The The invention relates to a method for producing a composite component according to the preamble of claim 1.
Ein
gattungsgemäßes Verfahren ist aus der
Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Verfahren dahingehend weiterzubilden, dass in einfacher Weise eine reproduzierbare hochgenaue Kontur und Querschnitt am Verbundbauteil bei gleichzeitiger Verringerung der Taktzeit im Herstellungsprozess ermöglicht wird.Of the Invention is based on the object, a generic To develop a method in such a way that in a simple way a reproducible high-precision contour and cross section on the composite component while reducing the cycle time in the manufacturing process is possible.
Die Aufgabe ist erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst.The Task is according to the invention by the features of claim 1.
Dank der Erfindung laufen der Umformprozess mittels IHU und der Spritzgießprozess nicht wie aus dem Stand der Technik bekannt nacheinander sondern gleichzeitig oder mit einer Überlappungszeit ab. Dadurch wird die benötigte Zeit zur Herstellung des Verbundbauteils enorm verringert, was das Verfahren besonders wirtschaftlich macht. Weiterhin wird auf Schieber oder bewegbare Kerne verzichtet, die – wie üblich – die Spritzgießkavität während der Umformung abdecken, so dass auch hier apparativer zeitlicher Aufwand für die Herstellung des Verbundbauteils eingespart wird. Des Weiteren wird durch das sich aufweitende Hohlprofil das eingespritzte im schmelzförmigen oder teigigen Zustand befindliche Spritzgießmaterial an die Werkzeuggravur gedrückt, wodurch dieses hochexakt die Kontur der Gravur nachbildet. Das Anpressen läuft insbesondere in der Erstarrungsphase des Spritzgießmaterials dem Schrumpfprozess entgegen, so dass die Kontur wie auch der Querschnitt des Spritzgießelements in ihrer hochexakten Ausprägung verbleiben. Hierdurch wird eine exakte Reproduzierbarkeit des entstandenen Verbundbauteils bei jedem Herstellungsvorgang gewährleistet. Ein externes Nachdrücken des Spritzgießmaterials kann in verfahrensökonomischer Weise entfallen, da der Druck von dem sich aufweitenden Hohlprofil über das hochgespannte Druckfluid geliefert wird. Durch den Andruck wird das Spritzgießmaterial besonders kompakt und homogen, so dass dessen mechanische Eigenschaften vergleichmäßigt werden, was auf die Verlässlichkeit des Spritzgießelements und damit des Verbundbauteils im Betrieb positiven Einfluss hat. Es ist auf jeden Fall beim erfindungsgemäßen Herstellungsprozess darauf zu achten, dass der Umformdruck, das heißt der Aufweitfortschritt auf die vorbestimmte Einspritzmenge und damit auf die Füllgeschwindigkeit der Kavität durch das Spritzgießmaterial abgestimmt ist, so dass sich das Spritzgießelement in der gewünschten Weise ausbilden kann. Das Verfahren wirkt sich zudem bei dünnwandigen Hohlprofilwerkstoffen und/oder Hohlprofilwerkstoffen geringer Duktilität bzw. geringer Bruchdehnung vorteilhaft aus, da die Schmelzwärme des Spritzgießmaterials die Umformbarkeit des Hohlprofilwerkstoffes begünstigt. Hierdurch sind in speziellen Fällen auch höhere Umformgrade beim Aufweiten des Hohlprofils erzielbar. Weiterhin wird vorteilhafter Weise verhindert, dass der Spritzgießdruck das Hohlprofil unliebsam einformt und damit des Kontur verändert, da der Umformdruck gleichermaßen einen inneren Stützdruck für das Hohlprofil gegen den Spritzgießdruck bildet. Des Weiteren bietet die Erfindung den Vorteil, dass in einer einzigen Gravur zwei formende Verfahrensarten auf das Hohlprofil angewendet werden ohne dieses zur Ausführung des einen oder anderen Verfahrens umzulegen. Dies erspart ebenfalls Herstellungszeit und verhindert sonst auftretende Fertigungstoleranzen.thanks The invention involves the forming process by means of hydroforming and the injection molding process not sequentially but as known in the art simultaneously or with an overlap time. Thereby becomes the time required to produce the composite component enormously reduced, which makes the process particularly economical. Furthermore, it dispenses with slides or movable cores, which - as usual - the Injection molding cavity during forming cover, so that also here expenditure of time for the production of the composite component is saved. Furthermore is by the widening hollow profile, the injected in the melt or doughy state located injection molding material pressed the tool engraving, making this highly accurate the Contour of the engraving replicates. The pressing runs in particular in the solidification phase of the injection molding the shrinking process counter, so that the contour as well as the cross section of the injection molding remain in their highly precise form. This will be a exact reproducibility of the resulting composite component at each Guaranteed manufacturing process. An external reprinting of the injection molding material can be in procedural economic Way omitted because the pressure of the expanding hollow profile over the highly stressed pressure fluid is supplied. By the pressure is the injection molding material is particularly compact and homogeneous, so that its mechanical properties are equalized, what about the reliability of the injection molding element and thus the composite component has positive influence during operation. It is definitely in the manufacturing process of the invention to make sure that the forming pressure, that is the Aufweitfortschritt to the predetermined injection quantity and thus to the filling speed the cavity matched by the injection molding material is, so that the injection molding in the desired Can train way. The method also affects thin-walled Hollow profile materials and / or hollow profile materials low ductility or low elongation at break advantageous because the heat of fusion of the Injection molding the formability of the hollow profile material favors. This is in special cases also higher degrees of deformation when expanding the hollow profile achievable. Furthermore, it is advantageously prevented that the Injection molding the hollow profile unwelcome einformt and thus the contour changed, because the forming pressure alike an internal support pressure for the hollow profile against forms the injection molding pressure. Furthermore, the invention offers the advantage that in a single engraving two molding process types be applied to the hollow section without this for execution one or the other process. This also saves Manufacturing time and prevents otherwise occurring manufacturing tolerances.
In einer bevorzugten Weiterbildung der Erfindung nach Anspruch 2 wird das Hohlprofil erst nach seiner Anlage an dem Gravurabschnitt, der an den Ausbauchbereich angrenzt, umspritzt. Hierdurch wird erreicht, dass das Spritzgießmaterial nicht zwischen das Hohlprofil und die Gravur in den Angrenzungsbereich gelangt, wodurch anderenfalls ein Teil der für die Ausbildung des Spritzgießelementes vorgesehenen Menge an Spritzgießmaterial gegebenenfalls unerwünscht verloren geht und daher das Spritzgießelement sich nicht richtig ausbilden kann. Weiterhin würde das Hohlprofil im Angrenzungsbereich nicht konturgerecht umgeformt werden, da das zwischen der Gravur und dem Hohlprofil liegende Spritzgießmaterial dies nicht zulässt. Der bei der zeitversetzten Umspritzung entstehende Zeitverlust in der gesamten Herstellung des Verbundbauteils ist jedoch unerheblich, da sich das Hohlprofil im Angrenzungsbereich aufgrund der geringen Distanz sehr schnell an die Gravur anlegt.In a preferred embodiment of the invention according to claim 2, the hollow profile is molded only after its attachment to the engraving section adjacent to the bulge region. This ensures that the injection molding material does not pass between the hollow profile and the engraving in the adjoining area, otherwise a portion of the intended for the formation of the injection molding of injection molding material may be undesirable lost and therefore the injection molding element can not form properly. Furthermore, the hollow profile in the adjoining area would not be reshaped contour-right, since the injection molding material lying between the engraving and the hollow profile does not permit this. However, the time lost in the time-delayed encapsulation in the entire production of the composite component is uner significant, because the hollow profile in the adjoining area due to the small distance very quickly applies to the engraving.
