Description

"Verfahren und Vorrichtung zur Herstellung gewickelter Kunststoffrohre, und gemäß diesem Verfahren hergestelltes Rohr""Method and device for the manufacture of coiled plastic pipes, and those manufactured according to this method Pipe"

Für Abwasserkanäle werden üblicherweise Rohre aus Beton benützt, obgleich solche Rohre schwer sind, und deshalb schwierig befördert und verlegt werden können; Entsprechende Rohre aus leichtem Kunststoff mit vergleichbaren Eigenschaften sind aber noch zu teuer, so daß meistens die bekannten und zuverlässigen Rohre dem unbekannten neuen Produkt vorgezogen werden.Concrete pipes are usually used for sewers, although such pipes are heavy and therefore difficult to move and install; Appropriate pipes from Light plastic with comparable properties are still too expensive, so that mostly the known and reliable Pipes are preferred to the unknown new product.

Kunststoffrohre mit verhältnismäßig kleinem Durchmesser können unmittelbar mit einer Strangpresse und einer Formdüse hergestellt werden. Bei größerem Rohrdurchmesser werden jedoch die 'Abmessungen der Presse und der Düse für eine wirtschaftliche Herstellung zu groß«Plastic pipes with a relatively small diameter can can be produced directly with an extruder and a forming nozzle. With a larger pipe diameter, however, the 'Dimensions of the press and the nozzle too large for economical production "

Rohre mit großem Durchmesser können jedoch so hergestellt werden, daß zunächst ein Kunststoffband erstellt wird, anschliessend dieses Band um einen Dorn zu einem Rohr mit dem gewünschten Durchmesser gewickelt wird, um danach die Bandwindungen miteinander zu verschweißen·However, pipes with a large diameter can be manufactured in such a way that a plastic band is first created, then this tape is wound around a mandrel to form a tube of the desired diameter, and then the tape turns to be welded together

Für Kanalrohre mit großem Durchmesser ist jedoch eine gewisse Steifheit und Festigkeit der Rohrwand erforderlich, was zu einer großen Wandstärke und Erhöhung der Materialkosten führt. Auch wird hierbei die Verarbeitung des Kunstatoffbandes schwieriger und kostspieliger·For sewer pipes with a large diameter, however, a certain rigidity and strength of the pipe wall is required, which leads to a large wall thickness and an increase in material costs. The processing of the plastic tape is also more difficult and expensive here.

Obgleich die Beförderungs- und Verlegungskosten von Kanalrohren aus Kunststoff wegen ihres geringen Gewichtes erheblich niedriger sein können als bei Betonrohren kann erst dann mit
einer allgemeinen Anwendung dieser Rohre gerechnet werden,
wenn der Preis der Kunststoffrohre niedriger als derjenige von Betonrohren wird.Although the transport and laying costs of sewer pipes made of plastic can be considerably lower than concrete pipes because of their low weight
a general application of these pipes can be expected,
when the price of plastic pipes becomes lower than that of concrete pipes.

Die Erfindung beabsichtigt ein Verfahren zu schaffen, .mit
welchem die Kosten der Herateilung von Kunststoffrohren verringert werden können.The invention intends to provide a method .mit
which the cost of dividing plastic pipes can be reduced.

Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, daß das Band vor dem Wickeln der Rohre die Form, eines aus der eigentlichen Rohrwand aiisragenden Einzel- oder Mehrfachprofils
hat, wobei das Mehrfachprofil aus voneinander getrennten Teilen bestehen kann, so daß nach dem Wickeln am Rohr schraubenlinienförmige Leisten entstehen.The method according to the invention is characterized in that, before the pipes are wound, the tape has the shape of a single or multiple profile protruding from the actual pipe wall
has, wherein the multiple profile can consist of separate parts, so that after winding on the pipe, helical strips are formed.

Insbesondere für Rohre mit nicht zu großem Durchmesser kann
dieses Profil hohl sein, während bei sehr großen Rohren ein
Vollprofil den Vorzug hat.Especially for pipes with a diameter that is not too large
this profile can be hollow, while in the case of very large tubes one
Full profile has the preference.

Dabei kann die Wand des Profiles oder der Profilteile, welche die Außenwand des fertigen Rohres darstellt, schmaler als die gegenüberliegende Wand sein, welche die eigentliche Rohrwand
bildet, während die Randteile letzterer Wand nach dem schraubenlinienförmigen Aufwickeln miteinander verbunden werden.
Die Randteile der Wand, die mit entsprechenden Teilen der benachbarten Windungen verbunden werden, können weiterhin abgeschrägt sein, um zusammen mit diesen benachbarten Teilen eine Rinne zu bilden, in welcher eine Schweißverbindung zwischenThe wall of the profile or the profile parts, which represents the outer wall of the finished pipe, can be narrower than the opposite wall, which is the actual pipe wall
forms, while the edge parts of the latter wall are connected to one another after the helical winding.
The edge parts of the wall, which are connected to corresponding parts of the adjacent turns, can further be chamfered in order to form, together with these adjacent parts, a channel in which a weld connection between

beiden hergestellt werden kann.both can be produced.

009845/1528009845/1528

Auch können die beiden Randteile der Wand als einander entsprechende Haken- oder Lippenprofile geformt sein, welche beim Aufwickeln bei aneinandergrenzenden Windungen ineinandergreifen. The two edge parts of the wall can also be considered to correspond to one another Be shaped hook or lip profiles, which interlock when winding with adjacent turns.

Bei einem solchen Verfahren kann insbesondere nach dem Auspressen des Bandes aus der Düse ein gekühltes Saugkaliber bekannter Form benutzt werden, um das ausgepreßte Band nachzuarbeiten, welches Kaliber erfindungsgemäß ein schraubenlinienförmiges Innenprofil besitzt, welches das ausgepreßte Band ä derart schraubenlinienförmig führt, daß darin die aufeinanderfolgenden Windungen des herzustellenden Rohres geformt werden, die aneinander anschließend dieses Kaliber verlassen und dann miteinander vereinigt werden. Auch ist es möglich das Band erst auf einen Dorn aufzuwickeln und die Windungen miteinander zu verbinden, und das derart erhaltene Rohr durch ein Saugkaliber hindurchzuführen, wo die Profile und Verbindungsnähte nachbearbeitet werden.In such a method, especially after the tape has been pressed out of the nozzle, a cooled suction caliber of known shape can be used to rework the pressed tape, which caliber according to the invention has a helical inner profile, which guides the pressed tape in a helical manner in such a way that the successive turns therein of the pipe to be produced, which subsequently leave this caliber and are then combined with one another. It is also possible to first wind the tape onto a mandrel and connect the windings to one another, and then pass the tube obtained in this way through a suction caliber, where the profiles and connecting seams are reworked.

Die Vorrichtung zum Durchführen eines solchen Verfahren^ welche eine Strangpresse und eine dem zu pressenden Profil angepaßte Preßdüse umfaßt, wird erfindungsgemäß gekennzeichnet durch ein hinter der Preßdüse angeordnetes zu kühlendes Saugkaliber, das mit einer der WiekelSteigung des aufzuwickelnden Bandes angepaßten schraubenlinienförmigen inneren Führungsfläche versehen ist.The apparatus for performing such a method ^ which comprises an extruder and a die adapted to the profile to be pressed, is characterized according to the invention by a Suction caliber to be cooled, which is arranged behind the press nozzle and which is matched with one of the inclination of the incline of the tape to be wound helical inner guide surface is provided.

Dabei folgt insbesondere auf diesem Kaliber ein Schweißgerät mit welchem die aufeinanderfolgenden Windungen miteinander vereinigt werden, wobei dieses Gerät auch zwischen einem üblichen Auf- · wickelgerät und dem Kaliber angeordnet sein kann.

Fig. 3 und 4 mit Fig. 1 bzw, 2 übereinstimmende Abbildungen eines zweiten Ausführungsbeispieles des erfindungsgemäßen Rohres.Fig. 3 and 4 with Fig. 1 and 2 corresponding images a second embodiment of the tube according to the invention.

Ein aus einem solchen Profil gewickeltes Rohr ist in Fig. 1 gezeigt, wobei deutlichkeitshalber eine Windung teilweise gelöst und im Schnitt dargestellt ist.A tube wound from such a profile is shown in Fig. 1, whereby, for the sake of clarity, a turn is partially detached and shown in section.

In Fig. 2 ist ein Querschnitt eines Bandprofiles dargestellt, ψ das zum Wickeln von Rohren mit einer Wandsteifheit bestimmt ist, welche im Verhältnis zur Materialstärke erheblich größer ist 'als bei aus Flachband gewickelten Rohren . .In Fig. 2 a cross section of a strip profile is shown, ψ which is intended for winding pipes with a wall stiffness which is significantly greater in relation to the material thickness than in the case of pipes wound from flat strip. .

Das gezeigte Profil umfaßt einen breiten Teil 1, welcher beim Aufwickeln die Innenwand des Rohres bilden muß· An den Teil 1 schließt sich ein trapezförmiger Teil 2 an, welcher mit dem Teil 1 einen Hohlraum 3 einschließt·The profile shown comprises a wide part 1 which, when it is wound up, must form the inner wall of the pipe.At part 1 adjoins a trapezoidal part 2, which with part 1 encloses a cavity 3

Die Materialstärke dieses Bandes ist derartig, daß das aus einem solchen Band gewickelte Rohr eine genügende Querfestig-The material thickness of this band is such that the tube wound from such a band has sufficient transverse strength.

Instead of a trapezoidal profile, a rectangular, triangular or rounded profile can also be used Profile "can be used.

Im dargestellten Fall ist der Teil 1 des Bandes an den Rändern 4 abgeschrägt. Beim Aufwickeln kommen diese abgeschrägten Teile 4 gegeneinander zu liegen, so daß eine V-förmige Rinne entsteht, in welcher leicht eine Schweißverbindung hergestellt werden kann.In the case shown, the part 1 of the tape is beveled at the edges 4. When winding these beveled parts come 4 to lie against each other, so that a V-shaped channel is created in which a welded connection is easily made can be.

Ein solches Profil wird mit Hilfe einer bekannten Formdüse mit einer zur Bildung des Hohlraumes 3 dienenden Zunge auf ununterbrochene Weise hergestellt. Um ein derart gebildetes Profil an der Außenseite auszuarbeiten und das Einsinken des noch weichen Material vorzubeugen, wird hinter der Düse ein Saugkaliber angeordnet, welches gekühlt wird, um eine Erstarrung des Kunststoffes in der gewünschten Form zu bewirken, und dabei die Oberfläche des Profiles in die gewünschte Form zu bringen.Such a profile is uninterrupted with the help of a known shaping nozzle with a tongue serving to form the cavity 3 Way made. To work out such a formed profile on the outside and the sinking of the still soft To prevent material, a suction caliber is placed behind the nozzle, which is cooled to prevent the To effect plastic in the desired shape, while bringing the surface of the profile into the desired shape.

Insbesondere wird erfindungsgemäß ein derartiges Kaliber benutzt, das eine schraubenlinienformige innere Führungsfläche besitzt, in welchem das ausgepreßte Band während des Erstarrens des Kunststoffes in die für das Aufwickeln gewünschte Form gebracht wird, während innerhalb dieses Kalibers ein den Innendurchmesser des Rohres bestimmter Dorn angeordnet 1st, so daß das Band dieses Kalibers mit aneinandergrenzenden Rändern der aufeinanderfolgenden Windungen verläßt· Auf diesem Kaliber kann dann unmittelbar ein Schweißgerät folgen, mit welchem die anschließenden Ränder aneinandergeschweißt werden. Da« miteinander Vereinigen der aufeinanderfolgenden Windungen geschieht vorzugsweise mittels eines Schweißvorganges, ob- In particular, according to the invention, such a caliber is used which has a helical inner guide surface in which the extruded band is brought into the shape desired for winding during the solidification of the plastic, while a mandrel which determines the inner diameter of the pipe is arranged within this caliber, see above that the band of this caliber leaves the successive windings with adjoining edges. A welding device can then immediately follow this caliber, with which the adjoining edges are welded to one another. Since the successive turns are preferably combined with one another by means of a welding process,

009845/1528009845/1528

gleich es auch möglich ist, dafür eine Klebeverbindung oder ähnliches zu benutzen. Zur Bildung einer Schweißverbindung kann ein Ultraschall- oder Hochfrequenzschweißgerät benutzt werden. Auch ist es möglich, einen Schweißdraht anzuwenden, insbesondere bei mit abgeschrägten Rändern 4 versehenen Bändern, die V-förmige Nuten zwischen den aufeinanderfolgenden Windungen bilden.it is also possible to use an adhesive connection or to use something similar. An ultrasonic or high frequency welder can be used to form a weld joint will. It is also possible to use a welding wire, especially in the case of tapes provided with beveled edges 4, which form V-shaped grooves between the successive turns.

Fig. 3+4 zeigen eine andere Profilform, welche aus einer Anzahl nebeneinanderliegender Profile gemäß Fig. 2 besteht. Da ein solches Band eine größere Breite hat, wird das Aufwickeln eines Rohres mit einer bestimmten Länge beschleunigt. Statt gesonderter trapezförmiger Profile mit durch Nuten 5 voneinander getrennten Außenwandteilen kann auch eine ununterbrochene Außenwand geformt werden, während auch rechteckige, dreieckige oder abgerundete Profile möglich sind«3 + 4 show another profile shape, which consists of a number of profiles lying next to one another according to FIG. There a such tape has a larger width, the winding of a pipe with a certain length is accelerated. Instead of separate Trapezoidal profiles with outer wall parts separated from one another by grooves 5 can also have an uninterrupted outer wall be shaped, while rectangular, triangular or rounded profiles are also possible «

Fig. 4 zeigt weiterhin eine andere Ausführung der miteinander zu verbindenden Ränder des Bandes, welche auch beim Einzelprofil nach Fig. 2 angewandt werden kann, während andererseits die abgeschrägten Ränder gemäß Fig. 2 beim Mehrfachprofil von Fig.4 ausgebildet werden können.Fig. 4 also shows another embodiment of the together to be connected edges of the tape, which can also be used in the individual profile according to FIG. 2, while on the other hand the beveled edges according to FIG. 2 can be formed in the multiple profile of FIG.

Wie in Fig. 4 gezeigt ist, sind die beiden Seitenränder des Bandes als zueinander konform ausgebildete Haken 6 und 7 ausgeführt, welche beim Aufwickeln ineinandergreifen. Es ist auch möglich, statt solcher Haken auch andere aneinander angepaßte Randprofile zu benutzen, welche das Herstellen einer Verbindung zwischen aneinandergrenzenden Windungen erleichtern. Ein Vorteil solcher ineinandergreifenden Randteile ist, daß dadurch die Berührungsfläche vergrößert wird, so daß eine festereAs shown in Figure 4, are the two side edges of the tape designed as mutually conformal hooks 6 and 7, which interlock when being wound. It is also possible to use other adapted edge profiles instead of such hooks, which enable the establishment of a connection between adjacent turns. A The advantage of such interlocking edge parts is that the contact area is enlarged, so that a firmer one

Verbindung erhalten wird.Connection is obtained.

Bei einer anderen Ausführungsform des erfindungsgemäßen Verfahrens wird das noch weiche, ausgepreßte Band in üblicher Weise um einen Dorn herumgewickelt, wobei die Windungen nachher aneinandergeschweißt oder geleimt werden» Dann wird das Band durch ein Kaliber mit schraubenlinienförraiger Innenwand hindurchgeführt, in welchem die Profile nachbearbeitet, und zugleich die Schweißnähte durch Andrücken verfestigt werden« Da die miteinander zu verbindenden Windungen noch weich sind, kann in vorteilhafter Weise zum Schweißen heiße Druckluft angewendet werden. Letzteres Verfahren kann natürlich auch bei der ersten Form des erfindungsgemäßen Verfahrens angewendet werden.In another embodiment of the method according to the invention the still soft, squeezed tape is wound around a mandrel in the usual way, with the turns afterwards be welded or glued together »Then that will Band passed through a caliber with a screw-shaped inner wall, in which the profiles were reworked, and at the same time the weld seams are strengthened by pressing «Since the coils to be connected are still soft, hot compressed air can be used advantageously for welding. The latter method can of course also be used the first form of the method according to the invention applied will.

Bei Rohren mit sehr großem Durchmesser kann es günstig sein, keine Hohl- sondern Vollprofile anzuwenden. Ein Vorteil der schraubenlinienformigen Hohl- oder Vollprofile ist, daß bei Querbelastung nicht die Gefahr besteht, daß die Kräfte in den dünneren Zwischenteilen verdichtet werden und zur Abscherung Anlaß geben, was zu einer erheblichen Materialersparung führt.In the case of pipes with a very large diameter, it can be advantageous not to use hollow profiles, but solid profiles. An advantage of the helical hollow or solid profiles is that with transverse load there is no risk that the forces in the thinner intermediate parts are compacted and give rise to shearing, which leads to a considerable saving in material.

Die Vorrichtung zur Herstellung derartiger Rohre wird mit einer mitlaufenden Säge ergänzt, mit welcher bestimmte Rohrenlängen abgesägt werden können. Weiterhin können zusätzliche Hilfsvorrichtungen vorhanden sein, mit welchen an diese Rohrabschnitte Flansche oder andere Kupplungsteile angeformt werden.The device for producing such pipes is supplemented with a rotating saw with which certain pipe lengths can be sawed off. Furthermore, additional auxiliary devices be present, with which flanges or other coupling parts are molded onto these pipe sections.

Da die vorragenden Profilteile 2 schraubenlinienförmig verlaufen, kann dieser Umstand dazu benutzt werden Kupplungshülsen oder dergleichen mit einem fertigen Rohr zu verbinden,Since the protruding profile parts 2 extend helically, this fact can be used for coupling sleeves or the like to be connected to a finished pipe,

Es wird klar sein, daß mit dem erfindungsgemäßen Verfahren in schneller und billiger Weise Rohre gewickelt werden können, deren Steifheit und Festigkeit im Verhältnis zur eigentlichen Materialstärke der Wand sehr groß sind. Es wird dadurch möglich Kunststoffrohre hoher Formfestigkeit herzustellen, deren Preis mindestens mit dem von Betonrohren vergleichbar ist, während das Gewicht dieser Rohre erheblich geringer ist, so daß die Beförderung und Verlegung solcher Rohre viel billiger als bei Betonrohren ist.It will be clear that with the method according to the invention in faster and cheaper way pipes can be wound, their rigidity and strength in relation to the actual Material thickness of the wall are very large. This makes it possible to produce plastic pipes with high dimensional stability Price is at least comparable to that of concrete pipes, while the weight of these pipes is significantly lower, so that the transportation and laying of such pipes is much cheaper than concrete pipes.

Innerhalb des Umfanges der Erfindung sind noch viele Änderungen möglich.Many changes are still within the scope of the invention possible.

Es ist weiterhin denkbar das Profil nach Fig. 2 ohne Randteile auszuführen und derart zu wickeln, daß die Innenwand des gewickelten Rohres von den aneinander anschließenden schmalen Teilen 2 der benachbarten Windungen gebildet wird, während die Abschrägung des' Profiles derart ist, daß die Außenwand von den ebenfalls aneinander anschließenden breiten Teilen 1 gebildet wird.It is also conceivable to run the profile according to FIG. 2 without edge parts and to wind it in such a way that the inner wall of the wound Tube is formed by the adjoining narrow parts 2 of the adjacent turns, while the The bevel of the 'profile is such that the outer wall is formed by the wide parts 1 also adjoining one another will.
