Description

Die den Gegenstand der Erfindung bildende Schweißeinrichtung für Rundbehälter, wie Kessel u. dgl., besitzt einen Wagen, auf dem zur Aufnahme des Rundbehälters dienende, von einem auf dem Wagen angebrachten Motor angetriebene Stützrollen gelagert sind und der in Achsrichtung gegenüber einem Schweißbrenner bzw. gegenüber einer Schweißelektrode vierfahrbar ist. Erfindungsgemäß sind auch die Wagenräder von dem Motor, und zwar wie die Stützrollen, über ;ein stufenlos regelbares Getriebe antreibbar. Da somit der gleiche Motor über ein stufenlos regelbares Getriebe sowohl die Stützrollen als auch die Wagenräder antreibt, kann der Vorschub bei Längs- und Rundschweißungen durch das Getriebe so eingestellt werden, daß die Geschwindigkeit stets konstant bleibt. Das ergibt Gleichmäßigkeit und unter den günstigsten Bedingungen hergestellte Schweißnähte. Hinzu kommt der weitere Vorteil, da.ß Schweißbrenner bzw. Schweißelektroden gegenüber den Bewegungen des Wagens feststehen.The welding device for round containers forming the subject of the invention, like boiler and the like, has a carriage on which to hold the round container serving, supported by a motor mounted on the carriage driven support rollers are and that in the axial direction opposite a welding torch or opposite a Welding electrode is four-wheeled. According to the invention are also the wagon wheels of the Motor, like the support rollers, can be driven by a continuously variable transmission. Since the same motor has both the support rollers via a continuously variable transmission as well as driving the cart wheels, the feed can be used for longitudinal and circular welds can be adjusted by the transmission so that the speed is always constant remain. This results in uniformity and produced under the most favorable conditions Welds. In addition, there is the further advantage that welding torches or welding electrodes are fixed in relation to the movements of the car.

An sich ist bei Werkzeugmaschinen Steuerung der verschiedenen Bewegungsrichtungen von einer Stelle aus bekannt, und bei Brennschneidemaschinen gehört es zum Stande der Technik, den den Brenner tragenden Kreuztisch von einem gemeinsamen Stellteile, meist deinem Laufrädchen, in zwei rechtwinklig zueinanderhegenden Richtungen zu bewegen.In machine tools, control of the various directions of movement is inherent Known from one place, and with flame cutting machines it is part of the status the technology, the cross table carrying the burner from a common control element, mostly towards your running wheel, in two directions at right angles to each other move.

Ein Ausführungsbeispiel- einer Schweißeinrichtung nach der Erfindung ist in der Zeichnung dargestellt, und zwar in Abb. i in Aufsicht und in Abb. z in Ansicht.An embodiment of a welding device according to the invention is shown in the drawing, namely in Fig. i in top view and in Fig. z in Opinion.

Der Gesamtantrieb und der zu schweißende Behälter sind auf einem auf Schienen fahrbaren Wagen 14 gelagert. 4 ist das stufenlos regelbare Getriebe, i der Antriebsmotor und 6 der dazugehörige Keilriementrieb. Auf der mit veränderlicher Drehzahl antreibbaren - Welle 9 des Getriebes 4 befinden sich zwei Kettentriebe Y und 7", die wechselweise über die ausrückbare Kupplung i i durch den Kupplungshebel I z ein- und ausgeschaltet werden können. Die auf- dem Wagen I4-befindlichen Antriebsstützrollen 5' und 5 sind durch die Zwischenwelle i o verbunden. Mit dem einen Ende- ruht der Behälter auf diesen beiden Antriiebsstützrollen 5' und 5 und somit auf dem Wagen 14, während er sich mit seinem anderen Ende auf zwei ebenfalls fahrbar angeordnete lose Rollen 16 stützt, die (s. Abb. i) in einem Rahmen drehbar gelagert sind.The entire drive and the container to be welded are on one Rails mobile carriage 14 mounted. 4 is the continuously variable transmission, i the drive motor and 6 the associated V-belt drive. On the with changeable Drivable speed - shaft 9 of the gear 4 are two chain drives Y and 7 ", which alternate via the disengageable clutch i i through the clutch lever I z can be switched on and off. The drive support rollers located on the trolley I4 5 'and 5 are connected by the intermediate shaft i o. With one end, the one rests Container on these two drive support rollers 5 'and 5 and thus on the carriage 14, while its other end is on two also arranged mobile supports loose rollers 16, which (see Fig. i) are rotatably mounted in a frame.

Zur Herstellung von Längsschweißungen ist der Kupplungshebel i 2 in die Stellung i 8 zu rücken.. Dadurch wird der Kettentrieb 7" eingeschaltet, der über ein Kegelradpaar 19 und über Schnecke 2o und Schneckenrad 2 i die Laufradachse 15 des Wagens 14 antreibt. Der Wagen kann nun nüt dem auf ihm über die Antriebsstützrollen 5' und 5 ruhenden Behälter mit der augenblicklich eingeregelten und für die Schweißung besten Geschwindigkeit in Längsrichtung bewegt werden, und der Schweißer kann seine Arbeit verrichten, ohne seinen Standort verlassen zu müssen.To produce longitudinal welds, the clutch lever i 2 must be moved into position i 8. This switches on the chain drive 7 ″, which drives the running wheel axle 1 5 of the carriage 14 via a bevel gear pair 1 9 and via worm 2o and worm gear 2 i The trolley can now be moved in the longitudinal direction using the container resting on it via the drive support rollers 5 'and 5 at the currently regulated speed that is best for welding, and the welder can do his work without having to leave his location.

Sollen mit dieser fahrbaren Schweißanlage Rundnähte geschweißt werden, so ist der Kupplungshebel 12 in die Stellung 22 zu bringen. Dadurch wird der Kettentrieb 7" ausgeschaltet und der Kettentrieb 7'eingeschaltet. Dieser versetzt über die Antrieb.sstützrollen 5' und 5 den Behälter in stufenlos regelbare Umdrehungen. In der Mittelstellung i3 des Kupplungshebels 12 sind beide Kettentriebe 7' und f" ausgeschaltet. Es ruht also der ganze Antrieb.If circular seams are to be welded with this mobile welding machine, the clutch lever 12 is to be brought into position 22. This creates the chain drive 7 "is switched off and the chain drive 7 'is switched on. This is offset via the drive support rollers 5 'and 5 the container in continuously adjustable revolutions. In the middle position i3 of the clutch lever 12, both chain drives 7 'and f "are switched off. It is at rest so the whole drive.

Mit der Erfindung ist jederzeit die günstigste Schweißgeschwindigkeit zu erreichen. Das Arbeitsgut kann vorwärts und, rückwärts gedreht werden, unter Selbsthemmung gegen unfreiwilliges Rollen des Arbeitsgutes.. Die Schweißgeschwindigkeit wird vom Standort des Schweißers aus gesteuert, und von dort wird auch die eingeregelte Schweißgeschwindiggkelt überwacht. Bei Längsschweißungen spielt die Länge der Schweißnaht keine Rolle. Der Schweißbrenner bzw. die Schweißelektrode kann, was für die Güte der Arbeit wesentlich ist, feststehend im Raume angeordnet sein, während der auf dem Wagen ruhende Behälter 17 mit beliebig einregelbaren _ Geschwindigkeiten am Schweißbrenner vorbeigeführt 'wird.With the invention, the most favorable welding speed can be achieved at any time. The work piece can be rotated forwards and backwards, with self-locking against unintentional rolling of the work piece. The welding speed is controlled from the location of the welder, and from there the regulated welding speed is also monitored. In the case of longitudinal welds, the length of the weld seam does not matter. The welding torch or welding electrode can, which is essential for the quality of the work, be arranged stationary in the room, while the container 17 resting on the carriage is guided past the welding torch at freely adjustable speeds.
