Description
ander abgesetzte Bereiche zu unterteilen, die selbstverständlich miteinander verbunden sein können.to subdivide different areas that can of course be connected to each other.
Weiterhin kann der Kraftstofftank so ausgebildet sein, daß der Beruhigungstopf zumindest auf Teilen seines Umfanges von der Tankwandung gehalten ist. Er kann von wenigstens einem in den Kraftstofftank hineinragenden Vorsprung der Tankwandung gehalten sein. Es besteht auch die Möglichkeit, daß ein Teil der Oberfläche des Beruhigungstopfes von Bereichen der Tankwandung umfaßt ist. Die Verbindung zwischen Beruhigungstopf und Tankwandung kann formschlüssig und/oder reibungsschlüssig sein. Ferner besteht die Möglichkeit, daß Beruhigungstopf und Tankwandung miteinander verschweißt sind. Der Beruhigungstopf kann ebenfalls aus thermoplastischem Kpnststoff bestehen.Furthermore, the fuel tank can be designed so that the swirl pot at least on parts its circumference is held by the tank wall. It can go into the fuel tank from at least one be held protruding projection of the tank wall. There is also the possibility that part of the Surface of the swirl pot is comprised of areas of the tank wall. The connection between The swirl pot and tank wall can be form-fitting and / or friction-locked. There is also the Possibility of the swirl pot and the tank wall being welded together. The calming pot can also be made of thermoplastic plastic.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigtAn exemplary embodiment of the invention is shown in the drawing. It shows
Fig. 1 einen Längsschnitt durch einen mit einem Beruhigungstopf versehenen Kraftstofftank, im Schema,1 shows a longitudinal section through a fuel tank provided with a swirl pot, in the scheme,
F i g. 2 und 3 einen Längsschnitt durch eine Hohlform zur Herstellung eines Tanks gemäß F i g. 1 mit der Hohlform in geöffneter und geschlossener Stellung.F i g. 2 and 3 show a longitudinal section through a hollow mold for producing a tank according to FIG. 1 with the Hollow form in open and closed position.
Bei dem in der Zeichnung dargestellten Ausführungsbeispiel ist der Beruhigungstopf 11 innerhalb des Kraftstofftankes 10 angeordnet. Letzterer ist mit einer Entlüftung 12, einem Rücklauf 14 sowie einem Auslauf 15 für die Flüssigkeit, der mit dem Motor verbunden ist, versehen.In the embodiment shown in the drawing, the swirl pot 11 is within the Fuel tank 10 arranged. The latter has a vent 12, a return 14 and an outlet 15 for the fluid connected to the motor.
Die in den F i g. 2 und 3 dargestellte Vorrichtung zum Herstellen des Kraftstofftanks gemäß F i g. 1 besteht im wesentlichen aus zwei Formteilen 27 und 28 sowie einem zugeordneten Blasdorn 29. F i g. 2 zeigt, daß zunächst zwischen die beiden geöffneten Formteile 27 und 28 ein schlauchförmiger Vorformling 30 eingeführt wird, der bspw. aus der Spritzdüse 31 eines Extruders austritt. Bevor dieser Vorformling 30 über den BlasdornThe in the F i g. 2 and 3 illustrated device for producing the fuel tank according to FIG. 1 consists of essentially of two molded parts 27 and 28 and an associated blow pin 29. F i g. 2 shows that a tubular preform 30 is first introduced between the two open mold parts 27 and 28 which exits, for example, from the injection nozzle 31 of an extruder. Before this preform 30 over the blow pin
29 geführt wird, wird auf einer Verlängerung 29a des letzteren das bereits fertige als Beruhigungstopf ausgebildete Konstruktionsteil 11 aufgesteckt, dessen größter Durchmesser kleiner ist als der Innendurchmesser des Vorformlings 30. Sobald letzterer die für die Herstellung des Werkstückes erforderliche Länge erreicht hat, wird die Hohlform durch Zusammenfahren der Formteile 27 und 28 in die in F i g. 3 der Zeichnung dargestellte Lage gebracht und somit geschlossen. Dabei werden die beiden Enden des Vorformlings 30 oben und unten zusammengequetscht. Der Vorformling29 is performed, is on an extension 29a of the latter, the already finished as a calming pot constructed structural part 11 attached, the largest diameter of which is smaller than the inner diameter of the preform 30. As soon as the latter has the length required for the production of the workpiece has reached, the hollow shape is made by moving the mold parts 27 and 28 together into the position shown in FIG. 3 of the drawing brought position shown and thus closed. The two ends of the preform 30 are thereby squeezed together at the top and bottom. The preform
30 wird durch das aus dem Blasdorn 29 austretende Druckmedium zu der durch das Formnest 32 vorher bestimmten Gestalt aufgeweitet, wobei der Beruhigungstopf 11 die in Fig.3 der Zeichnung dargestellte Lage einnimmt. Die Zeichnung läßt erkennen, daß die beiden Formteile 27 und 28 mit Vorsprüngen 33, 34 versehen sind, durch die das die Seitenwände des Kraftstofftankes 10 bildende Material bis zur Anlage an dem Beruhigungstopf eingezogen wird. Letzterer wird demnach zumindest an den beiden Stellen 35 und 36, auf Teilen seines Umfanges so von den Seitenwänden des Kraftstofftankes 10 umgeben, daß auch dann, wenn eine Schweißverbindung zwischen beiden Teilen nicht stattfindet, ein einwandfreier Sitz gewährleistet ist. Nachdem das Material erkaltet ist und seine Plastizität verloren hat, werden die Formteile 27, 28 auseinandergefahren. Nachdem der Blasdorn 29 zurückgezogen worden ist, kann das fertige Werkstück aus der Hohlform genommen werden. Es besteht natürlich auch die Möglichkeit, das fertige Werkstück nach oben vom Blasdorn 29 abzustreifen.30 is due to the pressure medium emerging from the blow mandrel 29 to that through the mold cavity 32 before widened certain shape, the swirl pot 11 shown in Figure 3 of the drawing Position. The drawing shows that the two molded parts 27 and 28 with projections 33, 34 are provided, through which the side walls of the fuel tank 10 forming material to the plant the swirl pot is drawn in. The latter is accordingly at least at the two points 35 and 36 Parts of its circumference so surrounded by the side walls of the fuel tank 10 that even if a Welding connection between the two parts does not take place, a perfect fit is guaranteed. After the material has cooled down and has lost its plasticity, the molded parts 27, 28 are moved apart. After the blow pin 29 has been withdrawn, the finished workpiece can be removed from the Hollow form can be taken. Of course, there is also the option of moving the finished workpiece upwards from Remove blow pin 29.
Anstelle des in der Zeichnung dargestellten schlauchförmigen Vorformlings können auch Folien oder Bänder als Zwischenerzeugnisse verwendet werden.Instead of the tubular shown in the drawing Preforms can also be used as intermediate products with foils or tapes.
