Bottle known. For this purpose, the cylindrical I n F i g. 1 is shown as an example of a tube shoulder piece 1 see the main part in the upper area tapering with screw thread, although one also forms, after which the shoulder piece can be inserted and tapered part using another appropriate shoulder piece with the application of heat. Fig. 2 shows a welding electrode and pressure being connected. This results in 40 trode 2 in the form of a cylindrical mandrel, which disadvantageously has a large contact surface between at its upper end a frustoconical body and shoulder and no reaching of the shoulder 3 and in a cylinder 4 shoulder piece edge on the inner wall of the cylinder - ends. The diameter of the mandrel corresponds to the threshing body after the connection. The total inner diameter of a tubular tube body is therefore also not 45 pers 6 into which this known method is to be introduced. The position for producing an optically and functionally functional tube body on the mandrel is determined by a flawless tube in a cost-saving manner collar 5, which is preferably formed by a suitable, adjustable ring.

F i g. 5 shows the counter-electrode to be produced, whereby the transition from the tube body, which is a ring-shaped metal part from a flat to the shoulder piece on the outside without a joint, is to take place ring 7 and a cylindrical ring that forms one piece, as and furthermore not serving as a welding electrode inside the tube 8 should remain unsealed shoulder edge. That includes. This metal part 7, 8 is firmly housed between a tube of the type mentioned at the beginning with an outer jacket 9 and an inner jacket 10 from di-minimum of material expenditure, electrical material. The inside has a shapely, smooth outside surface and the die surface is designed as a continuous surface which is also smooth on the inside, so that the profile of the tube to be produced is adapted,
there is no risk that the product will become stuck in the non- The annular weld seam and consequently also the welded section of the seam between the tubes- the cylindrical ring of the metal part 8 of the body and shoulder piece will stick, from where such a smaller diameter than that of the tube product empties poorly and where it is to the edge of the body 11 to heat the cylindrical bulges of the tube wall, which flat walls in the vicinity of the shoulder piece 1 adversely affect the overall impression of the tube through which undesired folds influence . form on the outer surface of the tube body

Diese Aufgabe wird erfindungsgemäß dadurch könnten.According to the invention, this task could thereby be achieved.

F i g. 6 zeigt deutlich die Stellungen des Schulterstücks 1, des rohrförmigen Tubenkörpers 6, des zylindrischen Doms der Schweißelektrode 2 und der Gegenelektrode mit ihren verschiedenen Teilen 7, 8,9 und 10 nach dem Einwärtsbördeln des oberen Randes 11 des rohrförmigen Tubenkörpers 6, wobei ersichtlich ist, daß der äußere Durchmesser des Schulterstücks 1 kleiner ist als der Innendurchmesser des Tubenkörpers 6. Der äußere Durchmesser des Schulterstücks 1 ist deshalb kleiner als derjenige der Schweißelektrode 2, weil sich während des Verschweißens ein auf eine schmale ringförmige Zone am Umfang beschränkter Auswalzvorgang abspielt, durch welchen der Durchmesser des Schulterstücks vergrößert wird.F i g. 6 clearly shows the positions of the shoulder piece 1, the tubular tube body 6, the cylindrical dome of the welding electrode 2 and the counter electrode with its various parts 7, 8, 9 and 10 after the upper edge 11 of the tubular tube body 6 has been flanged inwards, it being evident that that the outer diameter of the shoulder piece 1 is smaller than the inner diameter of the tube body 6. The outer diameter of the shoulder piece 1 is smaller than that of the welding electrode 2, because during the welding there is a rolling process limited to a narrow annular zone on the circumference, through which the diameter of the shoulder piece is increased.

Der dielektrische Außenmantel 9 der Gegenelektrode dient dazu, den vorher durch Erhitzung weich gemachten oberen Rand 11 des Tubenkörpers 6, welcher die Schweißelektrode 2 überragt, nach innen umzulegen. Die Erhitzung soll sich auf den oberen Rand des Tubenkörpers beschränken, der Rest soll auf einer niedrigeren Temperatur verbleiben. Nach dem Einwärtsbördeln wird der Rand des Tubenkörpers mittels Druck in die Randzone des Tubenschulterstücks 1 eingedrückt, welche sich bei der Verschweißung unter der Einwirkung von Hitze und Druck erweicht, wobei die Verschweißung vorzugsweise mit Hochfrequenz durchgeführt wird.The dielectric outer jacket 9 of the counter electrode is used to soften the previously by heating made upper edge 11 of the tube body 6, which protrudes beyond the welding electrode 2, inward to kill. The heating should be limited to the upper edge of the tube body, the rest should remain at a lower temperature. After inward crimping, the edge of the tube body becomes pressed by means of pressure into the edge zone of the tube shoulder piece 1, which is at the The weld softens under the action of heat and pressure, the weld being preferred is carried out with high frequency.

In Fig. 7, in welcher die gleichen Einzelheiten wie in Fig. 6 aber nach dem Verschweißen von Schulterstück und rohrförmigen Tubenkörper 6 dargestellt sind, ist bei 12 die Einbettung des einwärts gebördelten Randes 11 des Tubenkörpers 6 in die Schulter 20 des Schulterstücks gezeigt, wobei sich der Durchmesser dieser Schulter 20 durch den Preßdruck vergrößert hat. Die Schweißnaht wird durch den dem zylindrischen Ring 8 der Gegenelektrode gegenüberliegenden Ringbereich 13 begrenzt.In Fig. 7, in which the same details as in Fig. 6 but after the welding of the shoulder piece and tubular tube body 6 are shown, the embedding of the inwardly beaded edge 11 of the tube body 6 in the shoulder 20 of the shoulder piece is shown at 12, wherein the diameter of this shoulder 20 has increased due to the pressure. The weld seam is delimited by the ring area 13 opposite the cylindrical ring 8 of the counter electrode.

F i g. 8 zeigt ein Werkzeug, welches zum Verschweißen eines Schulterstücks 1 mit einem rohrförmigen Tubenkörper 6 geeignet ist, ohne daß der Rand des Tubenkörpers 6 einwärtsgebördelt wird. Man sieht deutlich, daß der Außendurchmesser des Schulterstücks 1 wesentlich kleiner ist als der Innendurchmesser des rohrförmigen Tubenkörpers 6.F i g. 8 shows a tool which is used for welding a shoulder piece 1 to a tubular Tube body 6 is suitable without the edge of the tube body 6 being crimped inward. It can be clearly seen that the outer diameter of the shoulder piece 1 is significantly smaller than the inner diameter of the tubular body 6.

Die Schweißelektrode 2 in Form eines Dorns gleicht im wesentlichen derjenigen nach dem vorherigen Ausführungsbeispiel, sie besitzt jedoch am Umfangsbereich ihrer Schulter 18 einen Ringwulst 19. Die Gegenelektrode besteht aus einem Metallteil 14 und einem nichtmetallischen oder dielektrischen Teil 15.The welding electrode 2 in the form of a mandrel is essentially the same as that of the previous one Embodiment, however, it has an annular bead on the circumferential area of its shoulder 18 19. The counter electrode consists of a metal part 14 and a non-metallic or dielectric Part 15.

F i g. 9 zeigt eine Stellung nach dem Verschweißen, wobei bei 16 deutlich der durch den Ringwulst 19 nach außen gedrängte Bereich der Schulter 20 des Schulterstücks 1 und bei 17 die Schweißnaht zu erkennen ist, welche zwischen dem Bereich 17 des Schulterstücks und der Innenwand des rohrförmigen Tubenkörpers 6 entsteht.F i g. 9 shows a position after the welding, with the one through the annular bead 19 clearly at 16 outwardly pushed area of the shoulder 20 of the shoulder piece 1 and at 17 the weld seam closed can be seen which between the region 17 of the shoulder piece and the inner wall of the tubular Tube body 6 is created.
