A male or female (1) connecting part is formed on at least one end of the pipe by external tool halves and forms a socket connection. An Independent claim is made for a process for production of a plastic pipe with a connecting part in which an extruded pipe is continuously corrugated by moving tool halves, and connecting ends are produced on the pipes by an interchangeable pair of tool halves.

Description

Die vorliegende Erfindung betrifft ein Anschlussteil an rohrförmigen Formteilen zur Verbindung solcher Formteile miteinander gemäß Oberbegriff des Anspruchs 1. The present invention relates to a connecting part on tubular shaped parts for connecting such molded parts together according to the preamble of the claim 1.

Steckverbindungen zwischen rohrförmigen Formteilen sind bekannt. Häufig werden diese so erstellt, dass ein männliches Anschlussteil eine Ringwulst aufweist mit dem es in ein weibliches Anschlussteil eingeführt wird, das eine entsprechende Ringnut besitzt. Das Herstellen dieser Ringnut erfolgt mit Hilfe von expandierenden Dornen, die zur Formgebung eingeführt werden (PCT-WO 97/10942, DE-A-36 13 579, FR-B-21 84 857). Diese Verfahren sind relativ aufwendig und können nicht kontinuierlich mit dem Herstellen des rohrförmigen Formteils ausgeführt werden, da immer der separate Arbeitsschritt des Einführen des Dorns vorhanden ist. Ein weiteres Problem ist es, dass durch das thermische Aufweiten der Anschlussteile die Wandstärke stellenweise verdünnt wird. Plug connections between tubular shaped parts are known. Frequently these are created in such a way that a male connecting part forms a ring bulge with which it is inserted into a female connector, the one has the corresponding ring groove. This ring groove is produced with the help of expanding mandrels that are introduced for shaping (PCT-WO 97/10942, DE-A-36 13 579, FR-B-21 84 857). These procedures are relative complex and cannot be continuous with the manufacture of the tubular Molded parts are carried out, since always the separate step of insertion of the thorn is present. Another problem is that due to the thermal Widening the connecting parts, the wall thickness is thinned in places.

Aufgabe der Erfindung ist es daher, ein Anschlussteil für rohrförmige Formteil, sowie ein Verfahren zur Herstellung solcher Formteile zu schaffen, bei dem in die kontinuierliche Herstellung solcher Formteile möglichst wenig eingegriffen wird. Aufgabe der Erfindung ist es weiter, Anschlussteile zu schaffen, die bei ihrer Verbindung möglichst dichtend ineinander eingreifen. Eine weitere Aufgabe der Erfindung ist es, Anschlussteile zu schaffen, die im Volumenanteil gegenüber der rohrförmigen Formteilen nicht verringert sind. The object of the invention is therefore to provide a connecting part for tubular shaped part, and to provide a method for producing such molded parts, in which in the continuous production of such molded parts is interfered as little as possible. The object of the invention is further to provide connecting parts, which in their Interlock the connection as tightly as possible. Another job of The invention is to create connecting parts that have a volume fraction compared to the tubular shaped parts are not reduced.

Diese Aufgabe wird mit den Merkmalen des kennzeichnenden Teils des Anspruch 1 gelöst. Fortbildungen und vorteilhafte Ausführungen der Erfindung sind in den weiteren Ansprüche umfaßt.

Dieses Anformen geschieht ohne Verlust im Volumentanteil gegenüber dem rohrförmigen Formteil. According to the invention is a connecting part on tubular shaped parts, the Molding consists of an extracted plastic tube that passes through from the outside movable mold jaws have been subjected to continuous shaping, characterized in that at at least one end of the plastic tube male or female connecting part for a plug-in connection is formed, and that the molding was done in outer moldings. This molding happens without loss in volume proportion compared to the tubular molded part.

Nach der bevorzugten Ausführung der Erfindung ist ein weibliches Anschlussteil zylindrisch ausgebildet und weist eine innere radial umlaufende Nut auf. Vorzugsweise ist die die Nut abgerundet. Dementsprechend weist ein männliches Anschlussteil eine Ringwulst auf. Vorzugsweise steigt die Ringwulst von vorne aus konisch ans und fällt von ihrer Spitze, d. h. ihrem maximalen Umfang aus steil oder sogar scharfkantig ab. Nach einer besondere Ausführung der Erfindung kann die Ringwulst einen Hinterschnitt aufweisen. According to the preferred embodiment of the invention is a female connector cylindrical and has an inner radially circumferential groove. The groove is preferably rounded. Accordingly, a male shows Connection part on an annular bead. The ring bead preferably rises from the front from conical to and falls from its top, d. H. their maximum extent from steep or even sharp-edged. According to a special embodiment of the invention the ring bulge has an undercut.

Erfindungsgemäß bilden ein weibliches und ein männliches Anschlussteil eine Steckverbindung, wobei die Ringwulst dichtend in der umlaufenden Nut anliegt. According to the invention, a female and a male connector form one Plug connection, the ring bead sealingly rests in the circumferential groove.

Ein erfindungsgemäßes. Verfahren zur Herstellung eines Formteils mit Anschlussteil nach einem der vorhergehenden Ansprüche ist gekennzeichnet durch die Schritte:
Extrudieren eines Kunststoffrohrs,
Unterwerfen des extrudierten Kunststoffrohrs einem Formgebungsverfahren,
wobei das Kunststoffrohr kontinuierlich durch jeweils zwei Formbacken auf endlos umlaufenden Bändern gleichmäßig geformt wird,
und wobei ein entsprechend einer gewünschten Länge des rohrförmigen Formteils einwechselbares Formbackenpaar als Form zur Herstellung eines Anschlussteils ausgebildet ist. Das Formbackenpaar zur Herstellung eines Anschlussteils ist für das jeweils männliche oder weibliche Anschlussteil auswechselbar. Nach einer besonders vorteilhaften Ausführung der Erfindung wird für die Herstellung eines männlichen oder weiblichen Anschlussteils ein kombiniertes Blas- und Vakuumformverfahren eingesetzt. Der Herstellungsprozess wird, zum Beispiel durch Beeinflussung des Extrusionstempos oder die Gestaltung der Formbacken zur Materialstauchung so gesteuert, dass der Volumenanteil insbesondere des aufgeweiteten weiblichen Anschlussteils gegenüber dem des Kunststoffrohrs nicht verringert ist. An inventive. A method for producing a molded part with a connecting part according to one of the preceding claims is characterized by the steps:
Extruding a plastic pipe,
Subjecting the extruded plastic tube to a shaping process,
whereby the plastic tube is continuously formed by two mold jaws on endless belts,
and wherein a pair of mold jaws which can be exchanged in accordance with a desired length of the tubular molded part is designed as a mold for producing a connecting part. The pair of shaped jaws for producing a connection part is interchangeable for the male or female connection part. According to a particularly advantageous embodiment of the invention, a combined blow molding and vacuum molding process is used to produce a male or female connecting part. The manufacturing process is controlled, for example by influencing the extrusion rate or the design of the mold jaws for material compression, in such a way that the volume fraction, in particular of the expanded female connecting part, is not reduced compared to that of the plastic tube.

Im folgenden wird die Erfindung anhand von Zeichnungen beispielhaft näher beschrieben. Es zeigen: In the following, the invention will be illustrated by way of example with reference to drawings described. Show it:

Fig. 1 ein weibliches Anschlussteil; FIG. 1 is a female connector;

Fig. 2 ein männliches Anschlussteil; Fig. 2 shows a male connector;

Fig. 3 die Verbindung der beiden Anschlussteile. Fig. 3 shows the connection of the two connecting parts.

Bei den Anschlussteilen handelt es sich um Kunststoff-Wellrohre (3, 3'), die extrudiert und kontinuierlich durch Formbackenpaare geformt werden. An den Enden werden wahlweise durch Blas- und Vakuumformtechnik männliche (2) und weibliche (1) Anschlussteile angeformt. Hierzu wird an passender Stelle ein Wellrohr-Formbackenpaar durch ein spezielles Formbackenpaar für das jeweilige Anschlussteil ersetzt. The connecting parts are plastic corrugated pipes ( 3 , 3 ') which are extruded and continuously formed by pairs of shaped jaws. At the ends, male ( 2 ) and female ( 1 ) connecting parts are optionally molded using blow and vacuum molding technology. For this purpose, a pair of corrugated tube mold jaws is replaced by a special pair of mold jaws for the respective connection part.

Das weibliche Anschlussteil 1 ist stufenweise in verschiedenen Durchmessern aufgeweitet, wodurch sich in einem Abstand zum vorderen Ende eine innere, umlaufende, abgerundete Ringnut 4 ergibt. Die Ringnut weist jedoch an ihrem vorderen Ende eine leichte Kante auf. Vor der Ringnut ist zunächst eine Einschnürung zur Bildung derselben vorhanden, an die sich zum vorderen Ende des Anschlussteils hin eine Aufweitung anschließt. Hinter der Ringnut besitzt das Anschlussteil einen Außendurchmesser wie das Wellrohr. Das männliche Anschlussteil 2 ist ebenfalls stufenförmig aufgebaut. Es erweitert sich von einem kleinen Durchmesser an der Spitze konisch zu einer Ringwulst 5, die dann relativ steil wieder auf einen kleineren Durchmesser zurückfällt. Dahinter entwickelt sich die Kontur wieder konisch aufweitend, bis der Außendurchmesser des Wellrohrs erreicht wird. The female connecting part 1 is gradually widened in different diameters, which results in an inner, circumferential, rounded annular groove 4 at a distance from the front end. However, the annular groove has a slight edge at its front end. In front of the annular groove there is first a constriction to form the same, which is followed by an expansion towards the front end of the connecting part. Behind the ring groove, the connection part has an outer diameter like the corrugated pipe. The male connecting part 2 is also constructed in a step-like manner. It widens conically from a small diameter at the tip to an annular bead 5 , which then falls back relatively steeply to a smaller diameter. Behind it, the contour widens conically again until the outer diameter of the corrugated pipe is reached.

Fig. 3 zeigt, wie das männliche Anschlussteil 2 mit seiner Ringwulst 5 in die Ringnut 4 des weiblichen Anschlussteils 1 eingreift. Durch passende Bemessung wird eine Rastverbindung hergestellt, bei der die Ringwulst 5 dichtend in der Ringnut 4 anliegt und eine - zwar lösbare - aber feste Verbindung herstellt. Die Dichtigkeit dieser Verbindung wird insbesondere durch die Kante der Ringnut gewährleist, an der die steil abfallende hintere Flanke der Ringwulst anliegt. Fig. 3 shows how the male connector 2 with its annular bead 5 in the annular groove 4 of the female connector part 1 engages. By suitable dimensioning, a snap-in connection is made, in which the annular bead 5 lies sealingly in the annular groove 4 and produces a connection, which is detachable but firm. The tightness of this connection is ensured in particular by the edge of the annular groove, against which the steeply falling rear flank of the annular bead rests.
