Der Erfindung liegt von daher die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zu schaffen, mit denen die hier in Rede stehenden Hohlkörper hergestellt werden können, die länger als die Breite des Metallbleches sind und ohne daß die vorerwähnten Schwierigkeiten bei der Herstellung der Schweißnähte bestehen, mit anderen Worten also gleichmäßige, hochwertige Schweißnähte an den Stirnwandungen erzielt werden können.The invention is therefore based on the object of a method and to create a device with which the hollow bodies in question here can be made that are longer than the width of the metal sheet and without the aforementioned difficulties in producing the weld seams, in other words, uniform, high-quality weld seams on the end walls can be achieved.
Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß von mehreren Vorratsspulen ablaufende Bänder nebeneinanderliegend zu einer breiten Bahn mit längsverlaufenden Nähten verbunden werden, beispielsweise durch fortlaufendes Verschweißen, wobei die Bahnbreite der Länge des fertigen Hohlkörpers entspricht.To solve this problem it is proposed according to the invention that Tapes running from several supply spools next to each other to form a wide one Web can be connected with longitudinal seams, for example by continuous Welding, the width of the track corresponding to the length of the finished hollow body.
Bei einer Vorrichtung zur Durchführung dieses Verfahrens mit einer Bandbundabwickelvorrichtung und einer einen Kernkörper tragenden Aufwickelvorrichtung, besitzt die Abwickelvorrichtung mehrere zur Aufwickelvorrichtung achsparallele Bundträger, denen in Bandabzugsrichtung arbeitende stationäre Schweißköpfe und eine Einrichtung zum Entfernen von Schweißnahtüberhöhungen, beispielsweise eine Fräseinrichtung, nachgeordnet sind.In an apparatus for performing this method with a Ribbon unwinding device and a winding device carrying a core body, the unwinding device has several collar carriers axially parallel to the winding device, stationary welding heads working in the strip take-off direction and a device for removing raised weld seams, for example a milling device, are subordinate.
Es ist vorteilhaft, die die Bahn bildenden Streifen mittels Nähten zu verschweißen, deren Stärke nicht geringer als die Hälfte der Streifendicke ist.It is advantageous to sew the strips forming the web to be welded, the thickness of which is not less than half the thickness of the strip.
Um die Erfindung näher zu erläutern, wird ein Beispiel zur Durchführung des Verfahrens und eine Vorrichtung dazu an Hand von Figuren beschrieben. Es zeigt F i g. 1 die erfindungsgemäße Vorrichtung in Seitenansicht, F i g. 2 die Vorrichtung in Draufsicht.In order to explain the invention in more detail, an example of its implementation is provided of the method and a device for this purpose are described with reference to figures. It shows F i g. 1 the device according to the invention in side view, FIG. 2 the device in plan view.
Die Vorrichtung (F i g. 1 und 2) weist einen Rahmen auf, an dem Haspeltrommeln 1 drehbar gelagert sind, die zum Abwickeln der Metallstreifen von Rollen dienen; ferner Schweißköpfe 2 zum Schweißen der Streifen in eine breite Bahn, weiterhin eine Vorrichtung 3, die für das dichte Aufwickeln der Bahn dient und die einen Antrieb aufweist, der die Fläche mit einer für das Schweißen erforderlichen Geschwindigkeit verschiebt.The device (Figs. 1 and 2) has a frame on which reel drums 1 are rotatably mounted, which are used to unwind the metal strips from rolls; furthermore welding heads 2 for welding the strips into a wide web, furthermore a device 3 which is used for the tight winding of the web and which has a drive having the surface at a speed required for welding shifts.
Die erfindungsgemäße Vorrichtung ist auch mit Vorrichtungen 4 zum Fräsen der Streifenkanten vor dem Schweißen ausgerüstet; diese Vorrichtungen sind im Sinne der Arbeitsrichtung vor den Schweißköpfen 2 angeordnet, die mit dem Pfeil A angezeigt ist. Hinter den Schweißköpfen 2 sind Vorrichtungen 5 zur Entfernung von Schweißnahterhöhungen, beispielsweise durch Fräsen oder Schleifen befestigt.The inventive device is also with devices 4 for Milling of the strip edges equipped before welding; these devices are in the sense of the working direction in front of the welding heads 2, indicated by the arrow A is displayed. Behind the welding heads 2 are devices 5 for removal by raised weld seams, for example by milling or grinding.
Für die Gestaltung der unteren Seiten der Schweißnähte können unter den Schweißköpfen Kühlschuhe, vorzugsweise aus Kupfer, angeordnet werden. In diesem Fall wird eine Wendetrommel 6 nicht gebraucht. Zum Gleichrichten der Streifen und zum Stutzen der Streifen während des Schweißvorganges sind ein Rollenrichtmechanismus 7 und Stützrollen 8 vorgesehen.For the design of the lower sides of the weld seams you can use Cooling shoes, preferably made of copper, are arranged on the welding heads. In this In this case, a turning drum 6 is not needed. To straighten the strips and A roller straightening mechanism is used to trim the strips during the welding process 7 and support rollers 8 are provided.
Die Zahl der Haspeltrommeln in der Vorrichtung hängt von der Zahl der zu schweißenden Streifen ab,. die für die Bildung der der Länge des Erzeugnisses entsprechenden Fläche erforderlich sind.The number of reel drums in the device depends on the number of the strips to be welded. those for the formation of the length of the product corresponding area are required.
Die Zahl der Schweißköpfe hängt von der Zahl der zu schweißenden Fugennähte und von der Art des Schweißens ab; das Schweißen kann einseitig oder zweiseitig in bezug auf die zu schweißenden Streifen ausgeführt werden.The number of welding heads depends on the number of seams to be welded and on the type of welding; the welding can be one-sided or two-sided with respect to the strips to be welded.
Die Einrichtung arbeitet erfindungsgemäß folgenderweise: Die Rollen der Metallstreifen, die zum Schweißen zu einer breiten Bahn bestimmt sind, werden auf den Haspeltrommeln befestigt. Vorzugsweise sollen Metallstreifen verwendet werden, die im kalten Zustande auf die Rollen aufgewickelt wurden, denn in diesem Falle weisen sie eine unbedeutende bleibende Deformation auf. Der Vorderrand jedes Streifens wird auf der Antriebstrommel zum dichten Aufwickeln der Fläche befestigt, wobei das Aufwickeln mit einer Geschwindigkeit erfolgt, die für das Schweißen der Streifen in den Fugen erforderlich ist. Das Schweißen der Streifen wird während des Rufwickelns der zu bildenden Bahn durchgeführt.According to the invention, the device works as follows: The roles of metal strips intended to be welded into a wide web attached to the reel drums. Metal strips should preferably be used, which were wound up on the rolls in the cold state, because in this case they show an insignificant permanent deformation. The leading edge of each strip is attached to the drive drum for tight winding of the surface, whereby the winding takes place at a speed suitable for welding the strips in the joints is required. The welding of the strips is carried out during the ring winding of the web to be formed.
Die Bearbeitung der Streifenkanten wird vor dem Schweißen mit den Fräsvorrichtungen 4 durchgeführt; nach dem Schweißen werden mit den Vorrichtungen 5 die Schweißnahterhöhungen entfernt, damit sie das dichte Aufwickeln der Bahn nicht stören.The processing of the strip edges is done before welding with the Milling devices 4 carried out; after welding are used with the jigs 5 removed the raised weld seams so that they do not prevent the web from being wound tightly disturb.
Die Schweißköpfe der Einrichtung werden stationär eingestellt, wenn nicht kleine Verschiebungen bei der Einstellung in Betracht gezogen werden; solche Verschiebungen sind auch für die Korrektur der Lage der Schweißköpfe während der Arbeit erforderlich.The welding heads of the facility are set stationary when not small shifts in the setting are taken into account; such Displacements are also used to correct the position of the weld heads during the Work required.
Bei dem zweiseitigen Schweißen wird das Umwenden der Fläche um 180° mit der Trommel 6 ausgeführt, wie es F i g. 1 zeigt. Beim zweiseitigen Schweißen werden zusätzliche Schweißköpfe verwendet.In the case of double-sided welding, the surface is turned over by 180 ° executed with the drum 6, as shown in FIG. 1 shows. When welding on both sides additional welding heads are used.
