Abstract
Description
Die Erfindung bezieht sich auf ein Glied für Stahlradiatoren, das aus zwei aneinanderliegenden Stahlblechen verschweisst ist, von denen jedes im Bereich jeder Stirnseite eine Nabe, zwischen den Naben mindestens zwei parallel verlaufende Rinnen und zwischen je zwei Rinnen eine mit der anliegenden Längssicke des anderen Stahlblechs verschweisste Längssicke aufweist.The invention relates to a member for steel radiators, which is welded from two adjacent steel sheets, each of which has a hub in the region of each end face, at least two parallel grooves between the hubs and one welded to the adjacent longitudinal bead of the other steel sheet between two grooves Has longitudinal bead.
Glieder der vorgenannten Art sind bekannt. Bei dem aus DIN 4722 bekannten Stahlradiator bestehen die Glieder aus gleichgeformten, spiegelsymmetrischen Stahlblechen; jedes Stahlblech weist am Rand einen umlaufenden Steg auf. Die Innenfläche des Stegs liegt mit den Innenflächen der Längssicken in derselben Ebene. Die umlaufenden Stege der aneinanderliegenden Stahlbleche werden ebenso wie die aneinanderliegenden Längssicken miteinander verschweisst. Ein Stahlradiator entsteht durch Aneinanderschweissen einer wählbaren Zahl von Gliedern im Bereich der Naben. Die verschweissten Stege bilden eine vorspringende umlaufende Kante des Glieds, die die Unfallgefahr erhöht. Auch bei dem aus DE-A-2 327 080 bekannten Blechradiator bestehen die Glieder aus gleichgeformten, spiegelsymmetrischen Blechen. Zwischen je zwei Rinnen ist aber keine mit der anliegenden Längssicke des anderen Blechs verschweisste Längssicke vorgesehen; vielmehr ein freier Raum, wodurch eine Art Röhrenradiator entsteht. Mit jeder Nabe ist im elektrischen Lichtbogen-Nahtschweissverfahren ein Rohr verbunden, welches die Verbindung mit dem Rohr des benachbarten Glieds herstellt. Zur Herstellung der einzelnen Glieder genügt es nicht, die äusseren Seitenränder der einander zugewandten Bleche miteinander zu verschweissen; vielmehr müssen auch die inneren Seitenränder miteinander verschweisst werden.Members of the aforementioned type are known. In the steel radiator known from DIN 4722, the links consist of uniformly shaped, mirror-symmetrical steel sheets; each steel sheet has a circumferential web at the edge. The inner surface of the web lies in the same plane with the inner surfaces of the longitudinal beads. The surrounding webs of the adjacent steel sheets are welded together, as are the adjacent longitudinal beads. A steel radiator is created by welding together a selectable number of links in the area of the hubs. The welded webs form a projecting circumferential edge of the link, which increases the risk of accidents. Even in the sheet metal radiator known from DE-A-2 327 080, the members consist of sheets of the same shape, mirror-symmetrical. However, no longitudinal bead welded to the adjacent longitudinal bead of the other sheet is provided between two channels; rather a free space, which creates a kind of tube radiator. A tube is connected to each hub in the electric arc seam welding process, which creates the connection with the tube of the adjacent link. To produce the individual links, it is not sufficient to weld the outer side edges of the sheets facing one another; rather, the inner side edges must also be welded together.
Hier will die Erfindung Abhilfe schaffen. Die durch den Anspruch gekennzeichnete Erfindung löst die Aufgabe, ein Glied für Stahlradiatoren der eingangs genannten Art unter Verwendung einfacher, aber allen Qualitätsansprüchen genügender Schweissungen so auszubilden, dass nicht nur vorspringende Kanten vermieden werden, sondern auch das Schweissen vereinfacht wird.The invention seeks to remedy this. The invention characterized by the claim solves the problem of designing a link for steel radiators of the type mentioned using simple welds which meet all quality requirements in such a way that not only are protruding edges avoided, but also welding is simplified.
Die durch die Erfindung erzielten Vorteile sind im wesentlichen darin zu sehen, dass kein umlaufender Steg vorhanden ist. Vielmehr wird - neben den Längssicken, die wie bisher verschweisst werden - der Rand des einen als Hohlkörper vorliegenden verformten Stahlblechs unmittelbar mit dem angelegten anderen Stahlblech verschweisst. Dabei sind die zu verschweissenden Stahlbleche nicht gleich - spiegelsymmetrisch. Aus den verschweissten Rinnen werden die Säulen eines Glieds das abgerundete Kanten aufweist; aus mehreren Gliedern entsteht ein Stahlradiator. Die Unfallgefahr ist verringert. Durch den Wegfall des umlaufenden Stegs wird überdies Material eingespart. Die Bautiefe des einzelnen Glieds und damit des Stahlradiators wird geringer. Der Stahlradiator ist schmaler. Als vereinfachtes Schweissverfahren für den Rand ist vorteilhaft ein Schutzgas-Schweissverfahren verwendet.The advantages achieved by the invention are essentially to be seen in the fact that there is no peripheral web. Rather, in addition to the longitudinal beads, which are welded as before, the edge of the deformed steel sheet, which is in the form of a hollow body, is welded directly to the other steel sheet that has been created. The steel sheets to be welded are not the same - mirror-symmetrical. The columns of a link with rounded edges become from the welded gutters; A steel radiator is created from several links. The risk of accidents is reduced. By eliminating the all-round web, material is also saved. The overall depth of the individual link and thus of the steel radiator is reduced. The steel radiator is narrower. A protective gas welding process is advantageously used as a simplified welding process for the edge.
Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels näher erläutert. Es zeigt:
- Fig. 1 eine Ansicht eines Glieds für einen Stahlradiator ohne umlaufende Kanten in verkleinertem Massstab;
- Fig. 2 einen Querschnitt durch das Glied entlang der Schnittlinie 11-11 in Fig. 1 etwa in natürlicher Grösse;
- Fig. 3 einen Querschnitt durch ein Glied nach der Erfindung.
- Figure 1 is a view of a link for a steel radiator without peripheral edges on a reduced scale.
- 2 shows a cross section through the link along the section line 11-11 in FIG. 1 approximately in natural size;
- Fig. 3 shows a cross section through a link according to the invention.
Die Glieder für einen Stahlradiator bestehen nach Fig. 1 aus je zwei Stahlblechen 1, die aneinanderliegen und miteinander verschweisst sind. Jedes Stahlblech 1 weist im Bereich jeder Stirnseite 2 eine Nabe 3 auf. An den Naben 3 ist jedes Glied mit den benachbarten Gliedern zu dem Stahlradiator verschweisst.The members for a steel radiator consist of two steel sheets 1 according to FIG. Each steel sheet 1 has a
Zwischen den Naben 3 sind in jedem Stahlblech 1 zwei parallel verlaufende Rinnen 4 vorgesehen. Nach dem Schweissen bilden zwei Rinnen eine Säule. Je nach Grösse und Ausstattung des Stahlradiators können mehr als zwei Säulen verwendet werden. Zwischen benachbarten Rinnen ist jeweils eine Längssicke 5 vorgesehen. Mit den Längssicken 5 liegen die Stahlbleche 1 desselben Glieds aneinander, ausserdem mit ihren äusseren Seitenwänden 7. Während die Säulen über den Bereich der Nabe 3 hinaus bis zur Stirnseite 2 verlängert sind, enden die Längssicken 5 auf der der Stirnseite 2 abgewandten Seite vor der Nabe 3. Auf diese Weise sind Vorlauf, Rücklauf sowie gleichmässige Verteilung eines Heizmediums, insbesondere von Warmwasser, über den Stahlradiator gewährleistet.Two parallel grooves 4 are provided in each steel sheet 1 between the
Bei dem in Fig. 1 und 2 dargestellten Glied für einen Stahlradiator sind die Stahlbleche 1 gleich geformt und liegen spiegelsymmetrisch mit den Rändern 6 ihrer äusseren Seitenwände 7 sowie den Längssicken 5 aneinander. Die Ränder 6 der Seitenwände 7 liegen mit der Innenfläche der Längssicken 5 in derselben Ebene. Die Seitenwände 7 sind nicht parallel zur Ebene der Längssicken 5 abgewinkelt; sie enden vielmehr mit den Rändern 6. Der gesamte Rand 6 des Stahlblechs 1 ist mit dem Rand des spiegelsymmetrisch angelegten Stahlblechs unter Bildung einer runden Schweissnaht 9 verschweisst. Das Verschweissen erfolgt insbesondere mit einem Schutzgas-Schweissverfahren. Die Längssicken 5 sind auf herkömmliche Weise miteinander verschweisst, z. B. mit einem Punkt-Schweissverfahren. Diese Ausführung hat zwar den Vorteil der Verwendung gleicher Stahlbleche; das Schweissen setzt jedoch die genaue Positionierung der Stahlbleche mit rundherum gleichmässigem Spalt zwischen den Rändern voraus.1 and 2 for a steel radiator, the steel sheets 1 have the same shape and are mirror-symmetrical with the
Deshalb sind bei dem in Fig. 3 dargestellten Ausführungsbeispiel nach der Erfindung die Stahlbleche 1 unterschiedlich geformt: Das Stahlblech l' weist eine höhere äussere Seitenwand 7' auf als das Stahlblech 1". Das Stahlblech 1' übergreift mit der höheren Seitenwand 7' die niedrigere äussere Seitenwand 7" des anderen Stahlblechs 1 " und liegt an der äusseren Rinne 4" an. Auch bei diesem Ausführungsbeispiel liegen die Längssicken 5 der Stahlbleche 1 aneinander. Der Rand 6' des Stahlblechs 1' ist aussen mit der Rinne 4" unter Bildung einer runden Schweissnaht 9 verschweisst. Die Schweissnaht 9 füllt die Stufe zur Rinne 4" aus. Die Schweissverfahren sind die gleichen wie bei den Fig. 1 und 2. Die hier beschriebene Ausführung hat den Vorteil des vereinfachten Schweissens. Dafür wird in Kauf genommen, dass die Stahlbleche 1', 1" nicht mehr gleich geformt sind.Therefore, in the exemplary embodiment shown in FIG. 3, the steel sheets 1 are shaped differently: the steel sheet 1 'has a higher outer side wall 7' than the steel sheet 1 ". The steel sheet 1 'overlaps the lower one with the higher side wall 7'
