Description

Geschweißte Längsnaht an Blechbehä.lterrümpfen, insbesondere Konservendosenrümpfen Es sind Längsnähte an Konservendosen mit abgekanteten und $anschartig aufeinandergelegten Rändern bekannt, von denen jeweils der eine L-förmig gestaltete Rand den andern nach außen weit überragt und bei denen beide Ränder an ihren Anlageflächen miteinander verschweißt werden müssen. Da die abgekanteten Ränder bei einer normalen Konservendose mit Rücksicht auf die wirtschaftlich bedingte Einsparung des Bleches um etwa 3 mm von dem Dosenrumpf abstehen, so ist es für die Massenfabrikation der Konservendosen ohne Herbeiführung von Kurzschlüssen und Verbrennungen der Schweißnaht praktisch unmöglich, eine elektrische Widerstandsschweißung mittels Elektrodenrollen zwischen den abgekanteten und flanschartig aufeinandergelegten Rändern des Dosenrumpfbleches herbeizuführen, wenn die eine Elektrodenrolle zwischen dem Umfang des Dosenrumpfes und dem höchstens 3 mm abstehenden, nach außen weit vorstehenden Schenkel des L-förmig gestalteten Randes eingebracht werden muß.Welded longitudinal seam on sheet metal container bodies, especially food can bodies There are longitudinal seams on food cans with bevelled and juxtaposed one on top of the other Edges known, of which one L-shaped edge is the other protrudes far beyond the outside and in which both edges on their contact surfaces with each other need to be welded. Because the bevelled edges of a normal tin can taking into account the economically required sheet metal savings of around 3 mm protrude from the can body, so it is for the mass production of the cans practically without causing short circuits and burns of the weld seam impossible to carry out electrical resistance welding by means of electrode rollers between the folded and flange-like edges of the can body plate bring about when the one electrode roller between the circumference of the can body and the outwardly protruding limb of the L-shaped, protruding at most 3 mm designed edge must be introduced.

Diese Nachteile werden bei der neuen geschweißten Längsnaht vermieden, wenn man die Breite des vorspringenden Schenkels des Uförmigen Randes gemäß der Erfindung der Dicke des anderen Blechrandes entsprechend wählt.These disadvantages are avoided with the new welded longitudinal seam, if the width of the projecting leg of the U-shaped edge according to the Invention of the thickness of the other sheet metal edge selects accordingly.

Die Zeichnung zeigt einen Teil des gerundeten Rumpfes a mit den abgekanteten, flanschartig aufeinandergelegten und in dieser Lage zusammengesVhweißten Rändern b, c im Querschnitt. Der Rand b ist nicht nur vom Blechrumpf a aus rechtwinklig abgebogen, sondern sein Vorderteil lt ist nochmals im wesentlichen rechtwinklig nach der Seite zu abgekippt, so daß sich im Querschnitt ein L-förmiger Rand b, A ergibt. Die Breite des vorspringenden Schenkels h dieses Uförmigen Randes ist erfindungsgemäß nur so groß wie die Dicke des anderen Blechrandes c. Neben dem nur einmal rechtwinklig abgekanteten Rande c des Blechrumpfes ist eine die fertiggestellte Längsnaht aufnehmende muldenartige Vertiefung d in bekannter Weise eingedrückt.The drawing shows part of the rounded fuselage a with the bevelled, Edges placed on top of one another in a flange-like manner and welded together in this position b, c in cross section. The edge b is not only at right angles from the sheet metal body a bent, but its front part is again essentially right-angled tilted to the side, so that in cross section there is an L-shaped edge b, A results. The width of the projecting leg h of this U-shaped edge is according to the invention only as big as the thickness of the other sheet metal edge c. Besides that only once at right angles The beveled edge c of the sheet metal body is one which receives the finished longitudinal seam trough-like depression d pressed in a known manner.

Der vorspringende Schenkellt des abgekanteten Randes b ergibt die Vorteile, daß beim Verschweißen der abgekanteten und flanschartig aufeinandergelegten Ränder b, c keine scharfen Spitzen durch Schweißspritzer entstehen können und daß nach dem Umlegen und Andrücken der Schweißnaht an den Dosenrumpf keine scharfen Blechkanten vorhanden sind, die beim Verschließvorgang Randverletzungen verursachen und beim Lackieren das Ablaufen des Lackes begünstigen können.The projecting leg of the beveled edge b gives the Advantages that when welding the folded and flanged one on top of the other Edges b, c no sharp points can arise from weld spatter and that after turning and pressing the weld seam against the can body, no sharp ones There are sheet metal edges that cause edge damage during the closing process and can encourage the paint to run off when painting.
