Description
24 34 482, ermöglicht, ausgehend von einem einzigen Formteil L-förmige Anschlußelemente mit an die jeweiligen Radiatorplatten hinsichtlich ihrer Weite angepaßter Radiatoranschlußöffnung zu versehen.24 34 482, made possible, starting from a single Molded part L-shaped connection elements with adapted to the respective radiator plates with regard to their width To provide radiator connection opening.
Zur Lösung dieser Aufgabe kennzeichnet sich das erfindungsgemäße Herstellungsverfahren dadurch, daß, ausgehend von einer Blechronde, zunächst durch Tiefziehen ein Topf geformt und daraufhin der Topf durch Stauchen seines oifenen Endbereichs nach innen zu dem im wesentlichen kugelförmigen Hohlkörper derart weiterverformt wird, daß die auf diese Weise eingezogene öffnung die hinsichtlich ihrer Weite vorgegebene, gegenüber dem Kugeldurchraesser kleinere Radiatoranschlußöffnung bildet, woraufhin anschließend im Bereich einer seitlich zusätzlich hergestellten Öffnung in der Wandung des Hohlkörpers die Rohranschlußmuffe aufgesetzt \ind mit dem Hohlkörper verschweißt wird.To solve this problem, the manufacturing method according to the invention is characterized in that, starting from a sheet metal blank, a pot is first formed by deep drawing and then the pot is further deformed by upsetting its open end region inward to form the essentially spherical hollow body in such a way that the in this way retracted opening which forms with respect to their width predetermined, opposite the Kugeldurchraesser smaller radiator connection port, whereupon then in the region of an opening laterally additionally produced in the wall of the hollow body, the pipe connection socket ind \ placed welded to the hollow body.
Der Vorteil des erfindungsgemäßen Herstellungsverfahrens liegt gegenüber herkömmlichen Fertigungsverfahren vor allem darin, daß es auf technologisch einfache Weise möglich ist, zu L-förmigen Anschlußelementen mit dem jeweiligen Bedarfsfall angepaßter Weite der Radiatoranschlußöffnung bei zugleich sehr kleinen Gesamtabmessungen zu gelangen. Das L-förmige Anschlußelement läßt sich auf diese Weise mit nur geringem Fertigungsaufwand als billiger Massenartikel in Großserien herstellen.The advantage of the manufacturing method according to the invention is compared to conventional manufacturing methods above all in the fact that it is possible in a technologically simple way to create L-shaped connection elements with the width of the radiator connection opening adapted to the respective case of need with at the same time very small Overall dimensions to arrive. The L-shaped connecting element can be in this way with only a little Manufacture manufacturing costs as a cheaper mass-produced item in large series.
Gemäß einer zweckmäßigen Weiterbildung kann der kugelförmige Hohlkörper auf der der Radiatoranschlußöffnung diametral gegenüberliegenden Seite mit einer Abflachung versehen werden, die die Bauhöhe des Anschiußelements URd damit auch die Anschlußbreite des gesamten Radiators weiterhin vermindertAccording to an expedient development, the spherical hollow body can be placed on the radiator connection opening diametrically opposite side are provided with a flattening that corresponds to the overall height of the Connection element URd thus also further reduces the connection width of the entire radiator
Diese Abflachung kann zweckmäßig dadurch hergestellt werden, daß bereits beim Tiefziehen der Blechronde ein Topf mit einem die spätere Abflachung bildenden ebenen Bodenteil geformt wird. Auf diese Weise läßt sich ein zusätzlicher Arbeitsgang für die Ausbildung der Abflachung avf der der Radiatoranschlußöffnung gegenüberliegenden Seite des kugelförmigen Hohlkörpers einsparen.This flattening can expediently be produced by the fact that the blank sheet metal is already deep-drawn a pot is formed with a flat bottom part which will later form the flat. That way lets An additional work step for the formation of the flattening avf that of the radiator connection opening opposite Save side of the spherical hollow body.
Gemäß einer bevorzugten Weiterbildung der Erfindung wird bei der Herstellung des Anschlußelements in der Weise verfahren, daß das radiale Einwärtsstauchen des in der ersten Fertigungsstufe vorgeformten Topfes zwecks Ausbildung der Kugelform des Hohlkörpers mittels zweier Stauchwerkzeuge durchgeführt wird, von denen das eine die bodenseitige Hälfte der Kugelaußenform und das andere die ter Radiatoranschlußöffnung zugeordnete Hälfte der Kugelaußenform des Hohlkörpers prägt. Pie beiden Stauchwerkzeuge können dabei im einfachsten Falle die Form zweier halber Hohlkugeln aufweisen. In jedem Falle bestimmt das eine der beiden Stauchwerkzeuge beim Prägen der der Radiatoranschlußöffnung zugeordneten Hälfte der Kugelaußen form des Hohlkörpers auch die Weite der Anschlußöffnung. Diese kann gegebenenfalls zugleich stutzenförmig vorkragend ausgebildet sein. Eine solche Ausbildung der Radiatoranschlußöffnung kann bei einem Anschlußelement für einzige Radiatorplatte nützlich sein, um ei» nen Stutzen für die Verschweißung oder Verschraubung zu erhalten oder um auf diese Weise gegebenenfalls einen ausreichenden Abstand der Rohranschlußmuffe von der Radiatorplatte einhalten zu können.According to a preferred development of the invention, in the manufacture of the connection element in proceed in such a way that the radial inward upsetting of the preformed in the first manufacturing stage pot is carried out for the purpose of forming the spherical shape of the hollow body by means of two upsetting tools one of which is the bottom half of the outer spherical shape and the other is the radiator connection opening associated half of the outer spherical shape of the hollow body. Pie two upsetting tools can do this in the simplest case have the shape of two half hollow spheres. In any case, that determines one of the two Upsetting tools when embossing the half of the outer sphere assigned to the radiator connection opening shape of the hollow body also the width of the connection opening. This can optionally also be nozzle-shaped be formed protruding. Such a design of the radiator connection opening can in the case of a connection element be useful for a single radiator plate, around a socket for welding or screwing to obtain or in this way, if necessary, a sufficient distance between the pipe connection sleeve to be able to comply with the radiator plate.
