Description
Verfahren und Vorrichtungen zum herstellen von Tuben Die Erfindung bezieht sich auf ein Verfahren und Vorrichtungen zum I;erstelien von Tuben durch Bilden eines dünnwandigen Tubenkörpers aus folien- oder schlauchförmigem Kunststoff und Aufbringen eines Kopfstückes auf den Tubenkörper. Methods and apparatus for making tubes The invention relates to a method and devices for I; creating tubes by Forming a thin-walled tube body from film-shaped or tubular plastic and applying a head piece to the tube body.
Es iDt bekannt, Tubenteile aus Kunststoff, wie einen dünnwandigen Tubenkörper und eienn Tubenkopf, durch Hochfrquenzschweissen mittels einer Elektrode und eines als Gegenelektrode dienenden, den Tubenkörper tragenden Dornes miteinander zu verbinden (österreichische Patenschrift 249 358). Bei diesem Hochfrquenzschweissen wird die Schweisswärme unmittelbar im Kunstoff durch die vom Kunststoff hervogerufene Kondensatorverlustleistung erzeugt. Bis Schweisswirkung ist daher in starkem Maß von den Materialeigenschaften des Kunststoffes abhängig.It is known to have tube parts made of plastic, such as a thin-walled one Tube body and a tube head, by high frequency welding by means of an electrode and a mandrel which serves as a counter electrode and carries the tube body with one another to connect (Austrian patent document 249 358). With this high-frequency welding is the heat of welding directly in the Plastic by the plastic generated capacitor power dissipation. Until the welding effect is therefore depends to a large extent on the material properties of the plastic.
Schon geringe Schwankungen in der Materialzusammensetzung sind daher geeignet, wesenliche Scwankungen in der Schweisstemperatur hervorzurufen. Das Hochfrequenzschweissen versagt dann vollends, wenn der mit dem Kopfstück zu verschweissende Tubenkörper eine Metalleilage enthält.Even slight fluctuations in the material composition are therefore suitable to cause substantial fluctuations in the welding temperature. The high frequency welding then fails completely when the tube body to be welded to the head piece contains a metal layer.
Es ist auch bekannt, Tubenteile unter Benutzung eines erhitzten Schweißstempels miteinander zu verbinden (DAS 1 062 004). Die Benutzung eines erhitzten Schweißstempels hat sich aber auch in der Praxis als nachteilig herausgestellt, insbesondere, wenn Kunststoffe verschweisst werden sollen, die relativ hohe Schweißtemperaturen verlangen. Darüber hinaus besteht der Machteil der Benutzung eines erhitzten Schweisskopfes oder Schweißstempels darin, dass die Schweißstellen verhältnismässig grossflächip werden und keine eng begrenzten Schweißstellen und Schweissnähte ausgeführt werden können, wie es beim Herstellen von Tuben erwttnscht ist Vor allem treten beim Arbeiten mit erhitzten Schweißstempel oder Schweissköpfen Beschädigungen und Verbrennungserscheinunggen an den umgebenden Kunststoffteilen in ausserordentlich starkem Maß auf, wenn eine VerbundfoLie für den Tubenkörper benutzt wird, die eine Metallschicht enthält. Bei Benutzung eines erhitzten Schweißstempels oder Schweisskopfes lässt sich das seitliche Abwandern von Wärme über die Metallschicht einer Verbundfolien in dem empfindlichen Bereich des Tubenkörpers nicht beherrschen, insbesondere dann nicht, wenn lait Temi?eraturen gearbeitet werden muss, wo ein echtes verschweissen und nicht nur ein gegenseitiges Versiegeln der Tubenteile notwendig ist.It is also known to weld tube parts using a heated welding die to be connected to each other (DAS 1 062 004). The use of a heated welding die but has also proven to be disadvantageous in practice, especially when Plastics that require relatively high welding temperatures are to be welded. In addition, there is the disadvantage of using a heated welding head or welding stamp in that the welds have a relatively large area and no tightly delimited welds and weld seams are carried out can, as is desired when making tubes, especially when working with heated welding stamps or welding heads damage and burns on the surrounding plastic parts to an extraordinarily high degree if a Composite foil is used for the tube body, which contains a metal layer. at The use of a heated welding stamp or welding head can be used on the side Migration of heat through the metal layer a composite film in Do not control the sensitive area of the tube body, especially then not when the temperature has to be worked where a real weld and not only a mutual sealing of the tube parts is necessary.
In der Regel ist aber ein festes Verschweissen von Tubenteilen unbedingt erforderlich, weil a beim Zusammendrücken des gefüllten Tubenkörpers recht erhebliche Kräfte an den Verbindungsstellen zwischen Tubenkörper und Kopfstück aufgenommen werden müssen.As a rule, however, a permanent welding of tube parts is essential required because a quite considerable when compressing the filled tube body Forces absorbed at the connection points between the tube body and head piece Need to become.
Der Erfindung liegt daher die Aufgabe zugrunde, durch Verfahrensmassnahmen und Vorrichtungsteile zu ermöglichen, Tuben auch dann aus einzelnen Teilen zusammenscweissen zu können, wenn Tubenteile, insbesondere der Tubenkörper, aus Verbundfolie mit einer Metallschicht besteht. Die Werstellungsweise soll einfach, leicht und billig durchführbar sein.The invention is therefore based on the object by means of procedural measures and device parts to enable tubes to be welded together from individual parts to be able to when tube parts, in particular the tube body, made of composite film with a Consists of a metal layer. The setting up should be simple, easy and cheap to implement be.
kiese Aufgabe wird gemäss der J3rfindung dadurch gelöst, dass der Tubenkörper dünnwandig mit einer zwischen Kunstsstoffschichten liegenden etallschicht ausgebildet wird und dass an Tubenkörper bzw. zwischen Tubenkörper und Kopfstück anzubringende Schweissverbindungen durch Induktionsschweissen, d . h. durch induktive 5 Erzeugen der für das Verschweissen notwendingen Wärme in der Metallschicht des Tubenkörpers, erzeugt werden. Durch die Erfindung wird ein echtes, dauerhaftes und festes Verschweissen der Tubenteile bei einem Tubenkörper erreicht, der eine Metallschicht enthält und demit das Hochfrquenzschweissen völlig ausschliesst und das Schwiessen mit erhitztem Sdhweisskopf wegen der über die Metallschicht abfliessenden Wärme praktisch unmöglich macht.This object is achieved according to the invention in that the Thin-walled tube body with a metal layer between layers of plastic is formed and that on the tube body or between the tube body and head piece Welded connections to be made by induction welding, d. H. by inductive 5 Generating the heat required for welding in the metal layer of the Tube body, are generated. The invention makes a real, permanent and Fixed welding of the tube parts achieved with a tube body that has a metal layer and thus completely excludes high-frequency welding and the welding with a heated welding head because of the drainage over the metal layer Makes heat practically impossible.
Man könnte zunächst annehmen, dass auch bei dem durch die Erfindung vorgeschlagenen Induktionsschweissen erhebliche Wärmemengen von der Metallschicht seitlich aus der Schweißstelle ebgeleitet würden. Es hat sich aber überraschend herausgestellt, dass die erforderliche Schweisswärrne auf induktivem Wege so schnell in der Metallschicht des Tubenkörpere erzeugt werden kann, dass die Gefahr des seitlichen Wärmeabtransportes sehr viel geringer als bei den Schweissverfahren mit erhitztem chweisskopf wird. Ausserdem ist die induktive Wärmeentsicklung genau dosierbar, was bei einem erhitzten Schweisskopf mit hoher Wärmekapazität nicht möglich ist. Das Induktionsschweissen gemäss der Erfindung sieht damit die Erzeugung einer möglichst geringen Wärmemenge bei geringer Wärmekapazität des Tubenkörpers in der Schweißstelle und damit schnelle Erzeugung der erfordereichen Schweisstemperatur bei genauer Dosierung der für das Verschweissen benötigten Wärmemenge vor. Da der Zeitablauf dieses Induktionsverschweissens sehr schnell ist, wird die von der Metallschicht seitlich abgeleitete Wärmemenge wesentlich gegenüber denjenigen Schweissverfahren verringert, bei denen die Wärme erst von einem geheizten Stempel auf die zu verschweissenden Kunststoffteile durch Wärmeleitung übertragen wird. Damit ist durch das Induktionsschweissen gemäss der Erfindung die Gefahr der Beschädigung des Tubenkörpers in Nachbarschaft der Schweissstellen schon wesentlich herabgesetzt.One could initially assume that also in the case of the invention proposed induction welding considerable amounts of heat from the metal layer would be discharged laterally from the welding point. It got surprising though showed that the required welding heat inductively so quickly can be generated in the metal layer of the tube body that the risk of the lateral Heat dissipation is much lower than with the welding process with heated welding head will. In addition, the inductive heat generation can be precisely metered, which is not possible with a heated welding head with high heat capacity. The induction welding according to the invention thus sees the production of one as possible low amount of heat with low heat capacity of the tube body in the weld and thus rapid generation of the required welding temperature with precise dosing the amount of heat required for welding. Since the timing of this induction welding is very fast, the amount of heat laterally dissipated by the metal layer significantly reduced compared to those welding processes in which the heat only by a heated stamp on the plastic parts to be welded Heat conduction is transferred. Thus, by induction welding according to the Invention the danger the damage to the tube body in the vicinity the welding points already significantly reduced.
Naturgemäss kann die Wärmeableitung durch die Iqetallschicht des Tubenkörpers nicht völlig unterbunden werden. Normalerweise ist aber die über die dünne Metallschicht abwandernde Wärmemenge nicht für die der Schweißstelle benachbarten Bereiche schädlich.Naturally, the heat can be dissipated through the metal layer of the tube body cannot be completely prevented. Usually it's over the thin metal layer The amount of heat that migrates away is not harmful to the areas adjacent to the weld.
Wenn jedoch besondere Erschwernisse vorliegen, beispielsweise die Metallschicht der Verbundfolie relativ dick im Vergleich zu den Kunststoffschichten ist oder wenn kunststoffe vorgesehen sind, die eine relativ hohe Verschweissungstemperatur haben, oder wenn Papierschichten in der Verbundfolie enthalten sind, also beispielsweise eine Verbundfolie aus Polypropylen-i>apier-Aluminium-Polypropylen-Schichten verarbeitet wird, empfiehlt es sich im Rahmen der Erfindung, die den Schweißstellen unmittelbar benachbarten Bereiche des Tubenkörpers während des Schweissvorganges zu kühlen. hierdurch werden jegliche schädliegen Einflüsse der über die Metallschicht aus der Schweißstelle abwandernden Wärme auf die sehr empfindliche Verbundfolie vermieden, insbesondere, dass bei der besonders empfindlichen, Papier enthaltenden Verbundfolie das Papier und teilweise auch das Kaschiermittel im Bereich und in Nachbarschaft der Schweissnaht mehr oder weniger gelbliche Blasen bilden.However, if there are particular difficulties, such as the Metal layer of the composite film relatively thick compared to the plastic layers is or if plastics are provided that have a relatively high welding temperature have, or if paper layers are contained in the composite film, so for example a composite film made of polypropylene-paper-aluminum-polypropylene layers is processed is, it is recommended in the context of the invention, the welds directly to cool adjacent areas of the tube body during the welding process. this removes any damaging influences from the over the metal layer Heat migrating from the welding point to the very sensitive composite film is avoided, in particular that in the case of the particularly sensitive composite film containing paper the paper and partly also the laminating agent in the area and in the vicinity the weld seam forms more or less yellowish bubbles.
Lurch das Verfahren gemäss der Erfindung ist somit die Möglichkeit geschaffen, auch unter schwierigen Bedingungen jegliche Beschädigungen am Tubenkörper durch den Schweissvorgang zu vermeiden und trotzdem ein sicheres, festes Verschweissen such unter schwierigen Voraussetzungen, d.h. unter der Notwendigkeit hoher Schweisstemperaturen zu gewährleisten.With the method according to the invention there is thus the possibility created, even under difficult conditions Damage on the tube body through the welding process and still a safe, permanent welding is sought under difficult conditions, i.e. under necessity to ensure high welding temperatures.
Durch die Erfindung sollen auch Vorrichtungen zur Durchführung des neuartigen Verfahrens geschaffen werden, die sicherstellen, dass das Grundprinzip der Induktionsverschweissung bei den verschiedenen Schweißstellen an einer zusainiiengeschweissten Tube eingehalten wird. Dies wird bei den Vorrichtungen gemäss der Erfindung dadurch erreicht, dass eine der jeweiligen Schweissstelle angepasste Induktionsspule und ein den Tubenkörper in Wärme übertragender Bertthrung tragendes Element vorgesehen sind, wobei das den Tubenkörper tragende Element mit hoher Wärmeleitfähigkeit und hoher Wärmekapazität ausgestattet ist.The invention is also intended to provide devices for performing the novel process to ensure that the basic principle induction welding at the various welding points on one welded together Tube is complied with. This is the case with the devices according to the invention achieved that an induction coil and an element carrying the tube body that transfers heat is provided are, the element carrying the tube body having high thermal conductivity and high heat capacity.
Beispielsweise kann im Rahmen der Erfindung die Einrichtung zum Verschweigsen des Tubenkopfes mit dem Tubenkörper eine axial zum Tubenkörper um diesen herumlaufende Induktionsspule, einen das Kopfstück auf den Tubenkörper pressenden Druckstempel und einen den Tubenkörper tragenden Dorn enthalten, wobei der orn aus Metall, vorzugsweise Aluminium besteht und an seinem oberen Ende einen der Tubenschülter und dem Nippel entsprechenden Kopf aus Polytetrafluoräthylen trägt, wobei die Metalloberfläche des Dornes bis an die Grundkanten der Tubenschulter reicht.For example, within the scope of the invention, the device for sealing of the tube head with the tube body an axially to the tube body running around this Induction coil, a pressure ram that presses the head piece onto the tube body and a mandrel carrying the tube body, the mandrel made of metal, preferably There is aluminum and at its upper end one of the tube shoulders and the nipple corresponding head made of polytetrafluoroethylene, the metal surface of the mandrel extends to the base edge of the tube shoulder.
Auf diese Weise wird sichergestellt, dass die Temperatur in dem zu verschweissenden Flächenbereich verhältnismässig hoch wird um ein sicheres Verschweissen des Tubenkörpere mit dem Tubenkopf zu erreichen, während in unmittelbarer zähe, d .h. an der Grundkante der Tubenschulter, bereits so viel Wärme abtransportiert wird, dass keine Beschädigungen, insbesondere Verbrennungserscheinungen an dem Material des Tubenkörpers auftreten.This will ensure that the temperature is in the too The surface area to be welded is relatively high in order to ensure reliable welding to reach the tube body with the tube head, while in the immediate tough, i.e. at the base of the tube shoulder, so much heat has already been removed that no damage, in particular burns, to the material of the tube body occur.

Einige Ausführungsbeispiele der Erfindung werden im folgenden anhand der Zeichnung näher erläutert. Es zeigen: aig. 1 schematisch eine Vorrichtung zum erstellen eines Tubenkörpers aus einem eine jjetallschicht enthaltenden Verbundfolienzuschnitt im Verfahren gemäss der Erfindung; Fig. 2 schematisch eine im Verfahren gemäss der Erfindung arbeitende Vorrichtung zum Befestigen eines Tubenkopfe 5 auf einem Tubenkörper aus einer eine Metallschicht enthaltende Verbundfolie vor dem Zusammenführen; Fig. 3 die Vorrichtung nach Pig. 2 nach dem Zusammenführen; Fig. 4 eine im Verfahren gemäss der Erfindung arbeitende Vorrichtung zum Zuschweissen des Bodens eines Tubenkörpers aus Verbundfolie mit Metallschicht und Fig. 5 eine etwas abgewandelte Vorrichtung gemäss der zrfindung zum Duschweissen des Tubenbodens.Some exemplary embodiments of the invention are based on the following the drawing explained in more detail. It show: aig. 1 schematically an apparatus for creating a tube body from a composite film blank containing a jetal layer in the method according to the invention; FIG. 2 schematically shows one in the method according to FIG Invention working device for fastening a tube head 5 on a tube body from a composite film containing a metal layer before being brought together; Fig. 3 the Pig device. 2 after merging; 4 shows one in the process According to the invention working device for welding the bottom of a tube body made of composite foil with metal layer and 5 shows a somewhat modified one Device according to the invention for shower welding of the tube base.
Für die Herstellung einer Tube im Verfahren gemäss der Erfindung kann ein rohrförmiger Tubenkörper 1 auf einem Rohrziehgerät mehrlagig mit Metalleinlage gezogen werden, Es kann auch ein Schlauch oder Rohr mit einer Ringdüse mehrschichtig mit Metalleinlage gespritzt werden. Bevorzugt wird man aber den Tubenkörper 1 aus einem Folienzuschnitt aus Verbundfolie, beispielsweise einer auf beiden Seiten mit Kunststoff wie Polyäthylen oder Polypropylen oder dgl. beschichteten Aluminiumfolie herstellen.For the production of a tube in the method according to the invention can a tubular tube body 1 on a tube drawing device in multiple layers with a metal insert A hose or pipe with a multi-layer ring nozzle can also be pulled be sprayed with a metal insert. However, the tube body 1 is preferred a foil blank made of composite foil, for example one on both sides with Plastic such as polyethylene or polypropylene or the like. Coated aluminum foil produce.
Iig. 1 zeigt ein Herstellungsbeispiel, bei welchem der Tubenkörper 1 aus einem Verbundiolienzuschnitt über einen Dorn 21 gewikkelt wird. Der Folienzuschnitt wird zunächst an einer Längsseite zu einem schmalen Falz 22 nach aussen umgelegt und mit dieser gefalzten längskante in eine flache Längsnut des Dornes 21 eingelegt. Dann wird der Zuschnitt fest um den Dorn herumgewickelt und mit der zweiten Längskante über den Falz 22 gelegt. Das Einlegen des mit Falz 22 versehenen Zuschnittrandes in die flache Längsnut 23 ist von besonderer Wichtigkeit, weil dadurch der Folienzuschnitt am gesamten Umfang des Dornes fest angezogen werden kann, und dadurch an jeder stelle gute wärmeleitende Berührung mit der Oberfläche des Dornes 21 hat, um die beim Schweissen auftretende Wärme sicher auf den Dorn 21 abführen zu können. Dazu ist der Dorn 21 aus gut wärmeleitendem Material, beispielsweise Aluminium, hergestellt und mit verhältnismässig grosser Wärmekapazität ausgestattet, so dass die an der Schweissnaht erzeugte Wärme nicht auf das Folienmaterial des Tubenkörpers abgeleitet wird. aus diese Weise werden jegliche Verbrennungen des Folienmaterials beim Schweissvorgang vermieden. Die Schweisselektrode ist im dargestellten Beispiel in Form einer sich über die gesamte Länge des Tubenkörpers 1 erstreckenden Induktionsschleife 24 ausgebildet, die zur Kühlung mit Wasser hohl ausgebildet ist. Diese schleife 24 ist, wie in Fig, 6 angedeutet, in einen Keramitkörper 25 eingesetzt, der zugleich als Andrückstempel dient, um die zusammenzuschweissenden Flächenbereiche der Längsnaht fest aufeinanderzudrücken, wenn dieser Stempel 25 gegen den Dorn 21 (oder umgekehrt) bedrückt wird. Der Stempel 25 kann auch aus hitzebeständigem Kunststoff, beispielsweise Tetrafluoräthylen bestehen.Iig. 1 shows a manufacturing example in which the tube body 1 is wound from a composite foil blank over a mandrel 21. The foil cut is first folded outwards on one long side to form a narrow fold 22 and inserted with this folded longitudinal edge into a flat longitudinal groove of the mandrel 21. Then the blank is wrapped tightly around the mandrel and with the second longitudinal edge placed over the fold 22. The insertion of the cutting edge provided with a fold 22 in the flat longitudinal groove 23 is of particular importance because it allows the film to be cut can be tightened on the entire circumference of the mandrel, and thus at every point has good heat-conducting contact with the surface of the mandrel 21 in order to prevent welding to be able to safely dissipate any heat that occurs on the mandrel 21. The mandrel 21 is for this purpose made of a material that conducts heat well, for example aluminum and equipped with a relatively large heat capacity, so that the Heat generated by the weld seam is not dissipated to the foil material of the tube body will. in this way, any burns to the film material during the welding process are avoided avoided. In the example shown, the welding electrode is in the form of a Induction loop 24 is formed over the entire length of the tube body 1, which is designed to be hollow for cooling with water. This loop 24 is, as in Fig, 6 indicated, inserted into a ceramic body 25, which also acts as a pressure stamp serves to firmly press the surface areas of the longitudinal seam that are to be welded together, when this punch 25 is pressed against the mandrel 21 (or vice versa). The Stamp 25 can also consist of heat-resistant plastic, for example tetrafluoroethylene.
Zum Befestigen des Tubenkopfes hat der Dorn 21, wse die Fig.To fasten the tube head, the mandrel 21, as shown in Fig.
2 und 3 zeigen, an einem Ende einen stirnseitig aufgesetzten ilopf 26 aus nicht leitendem Material, beispielsweise Polytetrafluoräthylen. Dieser Kopf 26 endet jedoch unmittelbar an der inneren Schulterumfangskante 27, so dass der aus Folie oder Schlauch gebildete Tubenkörper 1 bis an diese Schulterumfangskante 27 in unmittelbarer Berührung mit dem gut wärmeleitenden Material des Dornes 21 liegt. Aus den stirnseitigen Kopf 26 wird nach Fig. 7 ein Tubenkopfteil 2 aufgesetzt. Sodann wird der auf dem Dorn liegexide Tubenkörper t um eine Längste 6 über die Schulterumfangskante 27 vorgeschoben und entsprechend den Pfeilen 28 auf die Aussenfläche der Schulterplatte 5 des Kopfteiles 2 eingelegt.2 and 3 show, at one end, a head placed on the face 26 made of non-conductive material, such as polytetrafluoroethylene. That head 26 ends directly at the inner shoulder circumferential edge 27, so that the Tube body 1 formed from film or hose up to this shoulder circumferential edge 27 in direct contact with the highly thermally conductive material of the mandrel 21 lies. According to FIG. 7, a tube head part 2 is placed from the end head 26. Then the tube body t lying on the mandrel is laid by a longest 6 over the Shoulder circumference edge 27 advanced and according to the arrows 28 on the outer surface of the shoulder plate 5 of the head part 2 inserted.
Sodann wird der in Form eines konischen Ringes vorgebildete susätzliche Schulterteil 3 im Sinne des Pfeiles 29 auf das Tubenkopfstück 2 und den eingelegten Randbereich 6 des Tubenkörpers 1 gesetzt. Nach-dem so die einzelnen Teile zusammengefügt sind, wird der Preßstempel 30 im Sinne des Pfeiles 31 mit dem Dorn 21 und den auf diesem vereinigten Tubenteilen zusammengeführt. Der Preßstempel 30 enthält im dargestellten Beisniel eine Induktionssclileife 32, die, sobald sie unter Strom gesetzt wird, die Schulterplatte 5 des Tubenkopfes, den eingelegten IOndbereich 6 des Tubenkörpers 1 und den zusätzlichen Schulterteil3 erhitzt und unter des Druck des Stempels 30 fest und flächenmässig mitcinander verschweisst.Then the additional one pre-formed in the form of a conical ring Shoulder part 3 in the direction of arrow 29 on the tube head piece 2 and the inserted Edge area 6 of the tube body 1 is set. After that the individual parts were put together are, the ram 30 in the direction of arrow 31 with the mandrel 21 and the merged this united tube parts. The ram 30 contains in the illustrated For example an induction clip 32 which, as soon as it is energized, the shoulder plate 5 of the tube head, the inserted end area 6 of the tube body 1 and the additional shoulder part 3 heated and under the pressure of the stamp 30 firmly and horizontally welded together.
Der Preßstempel 30 kann wiederum aus keramischem Material oder hitzebeständigem Kunststoff bestehen. Es ist auch möglich, die Induktionsspule 32 getrennt von den Preßstempel 30 oberhalb einer Führungsbahn Für den Dorn 21 anzuordnen, so dass die zusammengesetzten Tubenteile auf dem Dorn 21 mit aufgesetztem Preßstempel 30 durch das Induktionsfeld bewegt werden, während die Induktionsspule selbst feststeht.The ram 30 can in turn be made of ceramic material or heat-resistant Made of plastic. It is also possible to separate the induction coil 32 from the To arrange ram 30 above a guide track for the mandrel 21 so that the assembled tube parts on the mandrel 21 with the ram 30 attached the induction field can be moved while the induction coil itself is stationary.
Es ist ohne weiteres möglich, die Ausbildung der Verbindung zwischen fl'ubenkopf und Tubenkörper abzuwandeln. Will man be;Lspielsweise den aus Verbundfolie gebildeten Tubenkörper 1 an der Unterseite der Schulterplatte 5 und der Innenseite des Nippels des Tubenkopfstückes verschweissen, so kann man einen Kopf 20 auf dem Dorn 21 benutzen, der einen entsprechend längeren Nippelteil aufweist. Man kann dann den oberen Teil des Tubenkörpers 1 über den Kopf 26 des Dornes 21 und um den Nippelteil des Kopfes 26 falten und dem das Tubenkopfstück 2 aufsetzen. Der eingefaltete Teil des Tubenkörpers 1 und das Kopfstück 2 werden donn in gleicher Weise wie oben beschrieben miteinander indulztiv verschweisst. Es ist auch möglich, ein dem zusätzlichen Schulterteil 3 nach Fig. 2 entsprechendes jedoch auf die Innenseite der Schulterplatte 5 des Tubenkopfstückes 2 passendes ringförmiges Element zunächst auf den Kopf 26 auf dem Dorn 21. zu legen, dann den oberen Teil des Tubenkörpers 2 über diesen zusätzlichen Ring zu falten und dann das Tubenkopfstück 2 aufzusetzen. Es werden dann in gleicher Weise wie oben beschrieben die drei übereinandergesetzten Elemente induktiv miteinander verschweisst.It is easily possible to form the connection between to modify the barrel head and barrel body. If you want, for example, the one made of composite film formed tube body 1 on the underside of the shoulder plate 5 and the inside weld the nipple of the tube head piece, so you can have a head 20 on the Use mandrel 21, which has a correspondingly longer nipple part. One can then the upper part of the tube body 1 over the head 26 of the mandrel 21 and around the Fold the nipple part of the head 26 and place the tube head piece 2 on it. The folded Part of the tube body 1 and the head piece 2 are then in the same way as above described indulztiv welded together. It is also possible to add one to the additional Shoulder part 3 according to FIG. 2, however, corresponds to the inside of the shoulder plate 5 of the tube head piece 2, first of all onto the head 26 to put on the mandrel 21st, then the upper part of the tube body 2 over this additional To fold the ring and then put on the tube head piece 2. It will then be in the same As described above, the three superposed elements inductively with one another welded.
Schliesslich ist es möglich, eine im Inneren des Tubenkopfstückes 2 verbleibende Nippelbuchse zunächst auf den Kopf 26 oder einen Kopf 26 mit verlängertem Nippelzapfen aufzusetzen, anschliessend den Tubenkörper über den Kopf 26 und um die Nippelbuchse zu falten und dann das Kopfstück 2 aufzusetzen. Auch in diesem Yall werden dann die übereinandergesetzten Elemente in der oben beschriebenen Weise induktiv miteinander verschweisst. Die Befestigung des Tubenkopfstückes im Induktivschweissverfahren lässt sich somit bei jeder denkbaren Verbindungsweise von Tubenkörper und Tubenkopfstück benutzen.Finally, it is possible to have one inside the tube head piece 2 remaining nipple socket initially on the head 26 or a head 26 with an extended Put on the nipple pin, then the tube body over the head 26 and around to fold the nipple socket and then put on the head piece 2. Also in this Yall are then the superimposed elements in the above described way inductively welded together. The attachment of the tube head piece In the inductive welding process, every conceivable connection method can be used use of tube body and tube head piece.
In allen Fällen wird eine flächenmässige Verschweissung des Tubenkörpers 1 mit dem Tubenkopf 2 erreicht, ohne dass Beschädigungen bzw. Verbrennungserscheinungen am Tubenkörper festgestellt werden.In all cases there is a surface welding of the tube body 1 achieved with the tube head 2 without damage or burns be determined on the tube body.
In vielen Fällen ist es erwünscht, die Tube schon bei ihrer 11erstellung an dem dem Tubenkopf entgegengesetzten Ende durch eine sich uuer erstreckende Schweissnaht zu verschliessen. Die Fig.In many cases it is desirable to have the tube ready when it is created at the end opposite the tube head by an extending weld seam to close. The fig.
4 und 5 zeigen schematische Einrichtungen, um eine solche quer verlaufende Schweissnaht zu erzeugen. Hierzu ist ein die Elektrode 33 enthaltender Druckstempel 34 aus keramischem Material oder hitzebeständigem Kunststoff, beispielsweise Tetrafluorätzylen, vorgesehen. Die Elektrode ist wiederum als sich über dic gesamte weite des Tubenkörpers erstreckende Indulftionsschleife ausgebildet, die zur Wasserkühlung hohl ist. Die Schleife 34 legt sich wie im Beispiel der Fig. 6 mit ihrem einen Schenkel direkt gegen. die Aussenfläche des Tubenkörpers 1. Als Gegendruckstück ist ein Block 35 aus. gut wärmeleitendem llaterial, beispielsweise Aluminium, und mit grosser Wärmekapazität vorgesehen, der wiederum die an der Schweissnaht erzeugte Wärme in unmittelbarer Umgebung der Schweissnaht sofort ableitet und aufnimmt, so dass es auch an der Querschweissnaht zu keinen VErbrennungserscheinungen an dem Tubenkörper 1 kommt. Wenn der Tubenkörper 1 aus einem Folienzuschnitt mit einer Längsnaht gebildet ist, sollte diese Längsnaht etwa mittig auf die Quernaht treffen. Zu diesem Zweck kann der Aluminiumblock 35 mit einem dünnen Gummibelag 56 versehen sein, in den sich die Längsnaht des Tubenkörpers 1 eindrücken kann und der trotzdem auch im Bereich der Längsnaht und zu beiden Seiten der Längsnaht ein sicheres Verschweissen in der Quernaht gewährleistet.4 and 5 show schematic devices to such a transverse To produce weld seam. For this purpose, a pressure stamp containing the electrode 33 is required 34 made of ceramic material or heat-resistant plastic, for example Tetrafluoroätzylen, intended. The electrode is in turn as extending over the entire width of the tube body extending Indulftionsschleife formed, which is hollow for water cooling. the As in the example of FIG. 6, loop 34 lies directly with one of its legs against. the outer surface of the tube body 1. A block 35 is used as a counter-pressure piece the end. material that conducts heat well, for example aluminum, and has a large heat capacity provided, which in turn, the heat generated at the weld seam in immediate vicinity of the weld seam immediately derives and absorbs so that it Even at the transverse weld seam, there are no signs of burns on the tube body 1 is coming. When the tube body 1 is formed from a foil blank with a longitudinal seam this longitudinal seam should meet the transverse seam approximately in the middle. To this end the aluminum block 35 can be provided with a thin rubber coating 56, in the the longitudinal seam of the tube body 1 can be indented and nevertheless also in the area the longitudinal seam and on both sides of the longitudinal seam a secure welding in the Cross seam guaranteed.
Dieser Gummibelag 36 soll aber nur so dünn und möglichst so wärmeleitend sein, dass keine Verbrennungserscheinungen im Bereich der Quernaht am Tubenkörper 1 auftreten. Fig. 5 zeigt eine Abwandlung der Einrichtung zur Herstellung der Quernaht. 111 diesem Fall ist ein etwas kleinerer Aluminiumblock 37 als Gegendruckstück vorgesehen, das an der dem Preßstempel 34 zugewandten Seite wiederum mit einem nachgiebigen Belag, beispielsweise einem Gummibelag 3, versehen ist. Zwischen diesem GuiiAbelag 38 und dem Tubenkörper 1 ist in diesem Fall eine Kupferfolie 39 eingelegt, die für eine gleichmässige Erzeugung und Verteilung der Schweisswärme sorgt und gleichzeitig überschüssige Wärme sofort über den Gummibelag 38 auf den Aluminiumblock 37 abführt, so dass es auch in diesem Beispiel zu keinen Verbrennungserscheinungen am Tubenkörper 1 in der hohe der Quernaht kommt.This rubber covering 36 should, however, only be as thin and as thermally conductive as possible ensure that there are no signs of burns in the area of the transverse seam on the tube body 1 occur. Fig. 5 shows a modification of the device for producing the transverse seam. 111 in this case a somewhat smaller aluminum block 37 is provided as a counter pressure piece, that on the side facing the ram 34 in turn with a flexible Covering, for example a rubber covering 3, is provided. Between this GuiiA topping 38 and the tube body 1, a copper foil 39 is inserted in this case, which for ensures even generation and distribution of the welding heat and at the same time Immediately dissipates excess heat via the rubber covering 38 onto the aluminum block 37, so that there are no signs of burns on the tube body in this example either 1 in the high of the cross seam.
