Abstract
Description
Die Erfindung betrifft einen Kunststofftank für Kraftfahrzeuge nach dem Oberbegriff des Anspruches 1 sowie ein Verfahren zur Herstellung eines solchen Kunststofftanks gemäß dem Oberbegriff des Anspruchs 2.The The invention relates to a plastic tank for motor vehicles according to the preamble of claim 1 and a method for producing such Plastic tanks according to the preamble of claim 2.
Kunststofftanks haben in Kraftfahrzeugen vor allem Vorteile bezüglich Gewicht, Formgebung und Herstellkosten. Allerdings muss bei dem jeweiligen Herstellungsverfahren speziell darauf geachtet werden, dass Innenteile im Behälter bereits in der Formgebung vorgesehen sind, oder dass Einlagen und/oder Öffnungen vorgesehen sind, die einen nachträglichen Einbau von Innenteilen ermöglichen. Vor allem sind schwallmindernde Einbauteile wie Schwallwände in der Press- oder Blasform vorzusehen.Plastic tanks have in automobiles especially advantages in terms of weight, shape and Production costs. However, in the particular manufacturing process Special care should be taken to ensure that internal parts in the container already are provided in the shaping, or that deposits and / or openings are provided, a subsequent installation of internal parts enable. In front all are noise-reducing components such as baffles in the To provide press or blow mold.

Aufgabe der Erfindung ist es, einen Kunststofftank für Flüssigkeiten und ein Verfahren zur Herstellung desselben aufzuzeigen, das ohne Einlegteile alle Anforderungen an einen solchen Kunststofftank für Flüssigkeiten erfüllt.task The invention is a plastic tank for liquids and a method for the production of the same show that without Einlegteile all Meets requirements for such a plastic tank for liquids.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale der Ansprüche 1 und 2 gelöst. Dadurch, dass aus einem vorgewärmten ersten Rohformling durch Abkanten oder Falten dieses Formlings ein zweiter Rohformling gebildet und dabei in diesem wenigs tens ein Schwallwand-Vorgebilde erzeugt wird, dessen beide Wände dann in der Blasform durch das Aufblasen aneinander angelegt werden, womit die endgültige Schwallwand gebildet wird, ist der Kunststofftank einschließlich Schwallwand ohne Einlegteile herstellbar. Die Anschlussstutzen für die Tankbefüllung und die Tankentlüftung sind bereits am ersten Rohformling vorgesehen. Die solchermaßen gebildete Schwallwand muss mit ihrer Unterkante einen bestimmten Abstand zum Tankboden haben, so dass die getankte Flüssigkeit nur langsam unter der Schwallwand in die durch die Schwallwand getrennten Kammern hin- und herströmen kann. Die erfindungsgemäß hergestellte Schwallwand hat weiterhin den Vorteil, dass durch sie der Tank erheblich versteift wird.These The object is achieved by the characterizing features of claims 1 and 2 solved. Thereby, that from a preheated first blank by folding or folding this molding a formed second Rohformling while doing in this least one Schwallwand-Vorgebilde is generated, the two walls then be applied in the blow mold by inflating each other, what the final Baffle is formed, the plastic tank including baffle can be produced without inserts. The connecting pieces for tank filling and the tank ventilation are already on the first blank. The thus formed Baffle must be with its lower edge a certain distance to the Tank bottom, so that the liquid tanked slowly under the baffle in the separated by the baffle chambers back and forth can. The inventively produced Baffle still has the advantage that through them the tank considerably is stiffened.
In einer Ausgestaltung der Erfindung wird der erste Rohformling mehrfach gefaltet. Dadurch entstehen im zweiten Rohformling mehrere vorgeformte Schwallwände. In der Blasform erhält man dann mehrere fertig geformte Schwallwände. Der Vorteil dieser Ausgestaltung ist, dass der Tank besonders formstabil ist und ein sehr gutes Crashverhalten hat.In In one embodiment of the invention, the first blank is multiply folded. This results in the second blank more preformed baffles. In the blow mold receives then you get several finished baffles. The advantage of this embodiment is that the tank is particularly dimensionally stable and a very good crash behavior Has.
Nachfolgend ist die Erfindung anhand der Zeichnung noch näher erläutert.following The invention is explained in more detail with reference to the drawing.

Die erfindungsgemäß hergestellten Kunststofftanks sind für alle Flüssigkeiten, die ein Kraftfahrzeug benötigt, geeignet, wie Kraftstoff, Öl, Bremsflüssigkeit, Scheiben- und Scheinwerfer- sowie Spiegelwaschwasser, Harnstoffwasserlösung und dergleichen.The produced according to the invention Plastic tanks are for all liquids, which requires a motor vehicle, suitable, such as fuel, oil, Brake fluid, Disc and headlight as well Mirror wash water, urea water solution and the like.
