Description
Die Erfindung betrifft ein Verfahren zum Herstellen eines Strukturbauteils aus einem faserverstärkten Kunststoff der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The invention relates to a method for producing a structural component made of a fiber-reinforced plastic specified in the preamble of claim 1. Art.
Die
Die
Es ist die Aufgabe der vorliegenden Erfindung, ein Verfahren zum Herstellen eines Strukturbauteils mit hohen Umformgraden, wie beispielsweise einen Frontendträger, in einer für eine Großserie geeigneten Weise bereitzustellen.It is the object of the present invention to provide a method for producing a structural component with high degrees of deformation, such as a front end support, in a manner suitable for mass production.
Diese Aufgabe wird mittels eines Verfahrens mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved by means of a method having the features of patent claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the dependent claims.
Ein erfindungsgemäßes Verfahren zum Herstellen eines Strukturbauteils aus einem faserverstärkten Kunststoff zeichnet sich dadurch aus, dass das Faserverbundhalbzeug vor dem Innenhochdruckumformen mittels des Umformschlauchs durch ein lokales Biegen umgeformt wird, während welchem mittels des Umformschlauchs ein Innenhochdruck auf das Faserverbundhalbzeug aufgebracht wird. Es ist also erfindungsgemäß vorgesehen, den Umformschlauch zusätzlich in einem dem Innenhochdruckumformprozess vorgelagerten Biegeverfahren einzusetzen, um einen entsprechenden Innenhochdruck auch während des Biegens auf das Faserverbundhalbzeug aufzubringen. Dadurch können durch das Biegen relativ hohe Umformgrade an dem Faserverbundhalbzeug erzielt werden, ohne dass dabei unerwünschte Querschnittsänderungen, wie beispielsweise ein Ausbeulen oder dergleichen, an dem Faserverbundhalbzeug entstehen. Vorzugsweise kann als Biegeverfahren ein Rotationszugbiegen eingesetzt werden, mittels welchem eine besonders präzise Umformung erfolgen kann.An inventive method for producing a structural component made of a fiber-reinforced plastic is characterized in that the fiber composite semifinished product is formed by a local bending before the hydroforming by means of Umformschlauch, during which an internal high pressure is applied to the fiber composite semi-finished by means of Umformschlauchs. It is therefore provided according to the invention to additionally insert the forming tube in a bending process upstream of the hydroforming process in order to apply a corresponding internal high pressure even during bending to the fiber composite semifinished product. As a result, relatively high degrees of deformation of the fiber composite semifinished product can be achieved by bending, without causing unwanted cross-sectional changes, such as buckling or the like, on the fiber composite semifinished product. Preferably, as a bending process a Rotationszugbiegen be used, by means of which a particularly precise deformation can take place.
Gemäß einer vorteilhaften Ausführungsform der Erfindung ist es vorgesehen, dass der Umformschlauch vor dem Innenhochdruckumformen auf einen Dorn extrudiert und mit dem Faserverbundwerkstoff ummantelt wird sowie anschließend der mit dem Faserverbundwerkstoff ummantelte Umformschlauch von dem Dorn abgezogen und zu dem Faserverbundhalbzeug abgelängt wird. Mit anderen Worten ist es vorgesehen, dass der Umformschlauch in einem Endlosverfahren auf einen Dorn extrudiert wird, wodurch eine besonders wirtschaftliche Herstellung des Umformschlauchs gegeben ist. Zusätzlich wird durch den Dorn sichergestellt, dass das Ummanteln des Umformschlauchs mit dem Faserverbundwerkstoff auf zuverlässige Weise erfolgen kann.According to an advantageous embodiment of the invention, it is provided that the forming tube is extruded before the hydroforming on a mandrel and coated with the fiber composite material and then the coated with the fiber composite forming tube is withdrawn from the mandrel and cut to the fiber composite semi-finished. In other words, it is provided that the forming tube is extruded in a continuous process on a mandrel, whereby a particularly economical production of the Umformschlauchs is given. In addition, it is ensured by the mandrel that the sheathing of the Umformschlauchs with the fiber composite material can be done in a reliable manner.
In weiterer vorteilhafter Ausgestaltung der Erfindung ist es vorgesehen, dass nach dem Innenhochdruckumformen mittels des Umformschlauchs das Faserverbundhalbzeug und wenigstens ein Faserverbundelement innerhalb des Innenhochdruckumformwerkzeugs mit einem Spritzgießmaterial umspritzt werden. Durch das kombinierte Innenhochdruckumformen und Spritzgießen können auf besonders schnelle und einfache Weise an dem Faserverbundhalbzeug zusätzliche Versteifungselemente in Form der Faserverbundelemente angebracht werden. Durch das Spritzgießen wird eine stoffschlüssige Verbindung zwischen den anzubringenden Faserverbundelementen und dem Faserverbundhalbzeug hergestellt.In a further advantageous embodiment of the invention, it is provided that after the hydroforming by means of the Umformschlauchs the fiber composite semi-finished product and at least one fiber composite element are encapsulated within the hydroforming with an injection molding material. Due to the combined hydroforming and injection molding additional stiffening elements in the form of fiber composite elements can be attached to the fiber composite semi-finished in a particularly fast and easy way. By injection molding a cohesive connection between the fiber composite elements to be mounted and the fiber composite semi-finished product is produced.
Bei einer weiteren vorteilhaften Ausführungsform der Erfindung erfolgt das Ummanteln des Umformschlauchs mit dem Faserverbundwerkstoff durch Flechtpultrudieren. Alternativ kann das Ummanteln des Umformschlauchs mit dem Faserverbundwerkstoff auch durch Thermoplastwickeln erfolgen. Mittels beider Verfahren wird eine besonders wirtschaftliche Ummantelung des Umformschlauchs mit dem Faserverbundwerkstoff ermöglicht, wobei durch das anschließende Ablängen des mit dem Faserverbundwerkstoff versehenen Umformschlauchs entsprechende Faserverbundhalbzeuge auf besonders einfache und wirtschaftliche Weise herstellbar sind, welche in den nachfolgenden Verfahrensschritten eingesetzt werden.In a further advantageous embodiment of the invention, the sheathing of the Umformschlauchs takes place with the fiber composite material by braiding pultrusion. Alternatively, the sheathing of the Umformschlauchs with the fiber composite material can also be done by thermoplastic winding. By means of both methods, a particularly cost-effective sheathing of the forming tube with the fiber composite material is made possible, whereby corresponding fiber composite semifinished products can be produced in a particularly simple and economical manner by the subsequent cutting to length of the forming tube provided with the fiber composite material, which are used in the subsequent method steps.
In weiterer vorteilhafter Ausgestaltung der Erfindung ist es vorgesehen, dass der Umformschlauch vertikal extrudiert und anschließend vulkanisiert wird. Durch die vertikale Extrusion entsteht weniger oder gar keine Reibung zwischen einem Extrudat, aus welchem der Umformschlauch hergestellt wird, und dem Dorn. Durch das anschließende Vulkanisieren wird der Umformschlauch entsprechend ausgehärtet, wonach dieser beispielsweise über einen Radius gezogen und in die entsprechende Flecht- oder Wickelanlage überführt werden kann, mittels welcher die Flechtpultrusion oder das Thermoplastwickeln erfolgt.In a further advantageous embodiment of the invention, it is provided that the forming tube is extruded vertically and then vulcanized. The vertical extrusion creates less or no friction between an extrudate from which the forming tube is made and the mandrel. By the subsequent vulcanization of the forming tube is cured accordingly, after which this can be drawn, for example, over a radius and transferred to the corresponding braiding or winding system, by means of which the braiding pultrusion or the thermoplastic winding takes place.
Gemäß einer alternativen Ausführungsform der Erfindung ist es vorgesehen, dass der Umformschlauch horizontal extrudiert und anschließend vulkanisiert wird. Dabei kann von der Seite horizontal auf den Dorn extrudiert werden, wobei der Vorteil dieser Variante darin besteht, dass die Lagerung des Dorns einfacher zu realisieren ist, da dieser hinter der Extrusionsanlage frei zugänglich ist.According to an alternative embodiment of the invention, it is provided that the forming tube is extruded horizontally and then vulcanized. It can be extruded horizontally from the side of the mandrel, the advantage of this variant is that the storage of the mandrel is easier to implement, since it is freely accessible behind the extrusion line.
Eine weitere vorteilhafte Ausführungsform der Erfindung sieht vor, dass der Umformschlauch während des Biegens und/oder während des Innenhochdruckumformens mittels eines Roboters abgedichtet und der Innenhochdruck des Umformschlauchs reguliert wird. Dabei kann das Faserverbundhalbzeug mitsamt dem Umformschlauch auf einfache Weise mittels des Roboters gehandhabt werden, wobei gleichzeitig eine Regulierung des Innenhochdrucks des Umformschlauchs erfolgen kann.A further advantageous embodiment of the invention provides that the forming tube is sealed during bending and / or during hydroforming by means of a robot and the internal high pressure of the forming tube is regulated. In this case, the fiber composite semi-finished product can be handled in a simple manner by means of the robot together with the forming tube, wherein at the same time a regulation of the internal high pressure of the Umformschlauchs can be done.
Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung ist es vorgesehen, dass vor dem Biegen wenigstens ein Ventil an dem Umformschlauch angebracht wird, mittels welchem während des Biegens und/oder während des Innenhochdruckumformens der Umformschlauch abgedichtet und der Innenhochdruck des Umformschlauchs reguliert wird. Dadurch kann auf besonders einfache Weise sichergestellt werden, dass der Innenhochdruck bedarfsgerecht reguliert bzw. aufrechterhalten werden kann.According to a further advantageous embodiment of the invention, it is provided that at least one valve is attached to the forming tube before bending, by means of which the forming tube is sealed during bending and / or during hydroforming and the internal high pressure of the forming tube is regulated. This can be ensured in a particularly simple manner that the internal high pressure can be regulated or maintained as needed.
Schließlich ist es in weiterer vorteilhafter Ausgestaltung der Erfindung vorgesehen, dass nach dem Innenhochdruckumformen oder nach dem Umspritzen des Faserverbundhalbzeugs und des wenigstens einen Faserverbundelements mit dem Spritzgießmaterial der Umformschlauch aus dem Faserverbundhalbzeug entnommen wird, wonach zumindest ein Endbereich des Faserverbundhalbzeugs anschließend erwärmt und unter Aufweitung des Endbereichs ein Einlegeelement aus einem Faserverbundwerkstoff eingeschoben sowie mit diesem verpresst wird, wonach wenigstens eine Metallbuchse an dem Endbereich angebracht wird. Das Einlegeelement dient dabei dazu, entsprechende Druckkräfte an einer Anbindungsstelle aufzunehmen und ein Fließen des Werkstoffs des Strukturbauteils zu verhindern. Mittels der Metallbuchse wird eine zusätzliche Fixierung und Stabilisierung des Endbereichs sichergestellt.Finally, it is provided in a further advantageous embodiment of the invention that after hydroforming or after encapsulation of the fiber composite semi-finished product and the at least one fiber composite element with the injection molding of the forming tube is removed from the fiber composite semi-finished, after which at least one end portion of the fiber composite semi-finished subsequently heated and widening of the end portion an insert element made of a fiber composite material is inserted and pressed with this, after which at least one metal bushing is attached to the end region. The insert element serves to receive corresponding pressure forces at a connection point and to prevent flow of the material of the structural component. By means of the metal bush, an additional fixation and stabilization of the end area is ensured.
