Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Formgebung von Kunststoffrohren, umfassend eine der Endform des gebogenen Rohres entsprechende Hülse, wobei die Hülse zum Einlegen des zu formenden Rohres auf ihrem Umfang geschlitzt ausgebildet ist, wobei die Hülse zur Stabilisierung ihrer Form durch Streben versteift ist.The The present invention relates to a device for shaping Plastic pipes, comprising one of the final shape of the bent pipe corresponding sleeve, the sleeve for inserting the tube to be formed slotted on its circumference is formed, wherein the sleeve is stabilized by struts to stabilize their shape.

Es ist bekannt, aus thermoplastischem Werkstoff bestehende Kunststoffrohre zur Formgebung unter Wärme in sogenannten Kavitäten auszuformen. Bei der Herstellung solcher Kavitäten wird bislang derart vorgegangen, dass entsprechend der Endform des zu verformenden thermoplastischen Rohres die Kavität entsprechend von Hand geformt wird, durch Streben versteift wird und dann die Kavität auf ihrem Umfang per Handarbeit mit einem Schlitz versehen wird, wobei der Schlitz derart ausgebildet ist, dass durch den Schlitz das zu formende Rohr eingelegt werden kann. Auf Grund der Form des Schlitzes ist jedoch sichergestellt, dass das Rohr allein nicht aus der Kavität herausgelangen kann. Das bedeutet, dass der Schlitz nicht parallel zur Längsachse des Rohres verlaufend ausgebildet sein kann, sondern vielmehr einen wellenförmigen Verlauf aufweist.It is known, made of thermoplastic material existing plastic pipes for shaping under heat in so-called cavities to mold. In the production of such cavities is so far proceeded, that according to the final shape of the thermoplastic pipe to be deformed the cavity is formed by hand, is stiffened by struts and then the cavity on its circumference is provided by hand with a slot, wherein the slot is formed such that through the slot the tube to be formed can be inserted. Due to the shape of the Schlitzes, however, ensures that the pipe is not alone from the cavity can get out. This means that the slot is not parallel to the longitudinal axis may be formed extending the tube, but rather a wavy History has.

Da insbesondere in der Automobilindustrie eine Vielzahl solcher Rohrleitungen hergestellt werden müssen, sind demzufolge auch eine Vielzahl von Kavitäten bereitzustellen, um die entsprechende Anzahl von Rohren herstellen zu können. Bislang ist es nun so, dass eine jede Kavität zur Aufnahme und Formgebung eines solchen aus thermoplastischem Kunststoff bestehenden Rohres gesondert per Hand gefertigt wird. Die Fertigung per Hand hat verschiedene Nachteile, u. a. den, dass die Fertigung relativ teuer ist. Insofern wird die Fertigung derartiger Kavitäten bereits im Ausland vorgenommen. Ein weiterer wesentlicher Nachteil besteht allerdings darin, dass auf Grund der Handfertigung derartiger Kavitäten die Kavitäten nie gleich oder identisch sind; dies gilt insbesondere für den Verlauf und die Ausprägung des Schlitzes. Dies führt insbesondere zu Problemen, wenn diese Kavitäten maschinell mit den zu verformenden Rohren bestückt werden sollen.There especially in the automotive industry a variety of such piping have to be produced Accordingly, a variety of cavities are also provided to the to produce appropriate number of pipes. So far it is like that that every cavity for receiving and shaping such a thermoplastic material existing pipe is made separately by hand. Production by hand has several disadvantages, u. a. that the manufacturing is relatively expensive. In this respect, the production of such cavities already made abroad. Another significant disadvantage exists However, in that due to the manufacture of such cavities, the cavities never are the same or identical; this applies in particular to the course and the expression of the slot. this leads to especially to problems when these cavities mechanically with the deformed Tubes fitted should be.

Der Erfindung liegt daher die Aufgabe zu Grunde, eine Vorrichtung der eingangs genannten Art bereitzustellen, die preiswert in der Herstellung ist, und die es darüber hinaus erlaubt, maschinell mit den entsprechenden zu verformenden Rohren bestückt zu werden.Of the The invention is therefore based on the object, a device of to provide the aforementioned type, which is inexpensive to manufacture, and it over it in addition, mechanically with the corresponding to be deformed Tubes fitted to become.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass die zu eingangs genannte Vorrichtung zur Formgebung von Kunststoffrohren als Gussteil ausgebildet ist. Nach der Herstellung einer Mutter- oder Urform können mithin von einer solchen Urform beliebig viele Gussteile als Vorrichtung zur Formgebung von Kunststoffrohren hergestellt werden, die zueinander alle identisch sind. Im Einzelnen ist in diesem Zusammenhang vorgesehen, dass zur Herstellung eines Gussmodels für die Vorrichtung zur Formgebung von Kunststoffohren als Gussteil, nach der Formgebung, dem Schlitzen und dem Verstreben der Hülse, die schlussendlich die Kavität für die Aufnahme des zu formenden Rohres bildet, aus der Hülse mit den Streben ein Gussmodell erstellt wird. Von diesem Gussmodell können dann beliebig viele Abgüsse gewonnen werden, wobei der Vorteil hierbei darin besteht, dass die Abgüsse in Form der jeweiligen Vorrichtung zur Formgebung von Kunststoffrohren alle identisch sind.The The object is achieved in that the device mentioned at the outset for the molding of plastic pipes is designed as a casting. After the production of a parent or Original form can Consequently, of any such original form as many castings as a device are made for molding of plastic pipes, each other all are identical. Specifically, it is provided in this connection that for the production of a casting model for the device for shaping of plastic pipes as a casting, after shaping, slitting and the bracing of the sleeve, the finally the cavity for the Recording of the tube to be formed forms, with the sleeve the pursuit of a casting model is created. From this cast model can then any number of casts be obtained, the advantage here is that the castings in the form of the respective device for shaping plastic pipes all are identical.

In diesem Zusammenhang ist in besonders vorteilhafter Weise vorgesehen, dass zur Herstellung des Gussmodells die Hülse mit den Streben in ihrer Form dreidimensional digital erfasst wird, wobei dann mit Hilfe der hieraus gewonnen Daten das Gussmodell erstellt wird. Vorteilhaft hierbei ist, dass der manuelle Aufwand zur Herstellung eines Gussmodells relativ gering ist, was schlussendlich die Herstellung derartiger Gussteile wesentlich verbilligt.In this connection is provided in a particularly advantageous manner that for the production of the casting model, the sleeve with the struts in their shape digitally captured in three dimensions, taking then with the help of this obtained data the casting model is created. Advantageous here is that the manual effort to make a casting model is relative low, which is ultimately the production of such castings much cheaper.

Nach einem weiteren Merkmal der Erfindung besteht die Vorrichtung zur Formgebung von Kunststoffrohren als Gussteil aus einer Messing-Kupfer-Legierung. Es hat sich herausgestellt, dass insbesondere mit Hilfe einer derartigen Messing-Kupfer-Legierung befriedigende Ergebnisse bei der Herstellung von Gussteilen erzielt werden können.To Another feature of the invention is the device for Shaping of plastic pipes as a casting from a brass-copper alloy. It has been found that in particular with the help of such Brass-copper alloy satisfactory results in the production of castings can be achieved.
