Description
Verfahren zum Befestigen eines elektrischen RohrheizkörpersMethod for attaching an electric tubular heater
Die Erfindung bezieht sich auf ein Verfahren zum Befestigen eines elektrischen Rohrheizkörpers in einem Gußkörper durch Einpressen des Rohrheizkörpers in eine im Gußkörper vorgesehene Nut.The invention relates to a method of attaching a electric tubular heater in a cast body by pressing in the tubular heater into a groove provided in the cast body.
Es ist bekannt, bei Gußkörpern dieser Art den Rohrheizkörper In die Nut einzupressen und durch bleibende Verformung der Nutränder in der Nut zu befestigen. Diese Art der Verbindung von Heizkörper und Gußkörper gewährleistet zwar einen guten Wärmeübergang hat aber den Nachteil, daß bei geringen Wandstärken der Nutenflanken ihre bleibende Verformung nicht möglich ist, da die Nutenflanken brechen.It is known that in cast bodies of this type the tubular heater In the Press in the groove and fix it in the groove by permanent deformation of the groove edges. This type of connection between the radiator and cast body ensures a good one However, heat transfer has the disadvantage that the groove flanks are thin when walled their permanent deformation is not possible because the groove flanks break.
Aufgabe der Erfindung ist es, ein Verfahren nach dem Oberbegriff des Anspruchs zu finden, durch welches eine einfache und technisch leicht realisierbare aber dennoch einwandfreie Befestigung des Rohrheizkörpers im Gußkörper möglich ist.The object of the invention is to provide a method according to the preamble of To find a claim through which a simple and technically easy to implement but perfect fastening of the tubular heater in the cast body is still possible.
Gelöst wird dlese Aufgabe dadurch, daß in den Flanken der Nut Löcher vorgesehen sind und daß während des Einpressens des Rohrheizkörpers In die Nut der Mantelwerkstoff des Heinzkörpers unter bleibender Verformung in die Löcher dringt.This problem is solved by making holes in the flanks of the groove are provided and that during the pressing of the tubular heater into the groove of the Shell material of the Heinz body penetrates the holes with permanent deformation.
Hierdurch wird erreicht, daß der während des Elnpressens In die Löcher eingedrungene Mantelwerkstoff den Rohrheizkörper einwandfrei In der Nut haltert. Eln Brechen der Nutenflanken wird selbst bei geringen Nutenwandstärken sicher vermieden. Der Elnpreßdruck kann bedenkenlos erhöht werden, wodurch ein noch besserer Wärmeübergang vom Heizkörper zum Gußkörper erreicht wird.This ensures that the during the Elnpressens in the holes Penetrating jacket material holds the tubular heater properly in the groove. Breaking of the groove flanks is reliably avoided even with thin groove wall thicknesses. The injection pressure can be increased without hesitation, resulting in an even better heat transfer is achieved from the radiator to the cast body.
-2- Ein Beispiel eines nach dem erfindungsgemäßen Verfahren befestigten Rohrheizkörpers Ist In den Zelchnungen dargestellt und wird im folgenden näher beschrleben. Es zelgen: Figur 1 die Seitenanslcht eines Gußkörpers und des Rohrheizkörpers vor dem Einpressen Im Schnitt; Figur 2 eine Seltenanslcht eines Gußkörpers mit elngepreßtem Rohrheizkörper Im Schnitt. -2- An example of one according to the invention Method of fixed tubular heater is shown in the drawings and is describe in more detail below. It shows: FIG. 1 the side view of a cast body and the tubular heating element before being pressed in. In section; Figure 2 is a rare view of a cast body with pressed tubular heating element In section.
In den Gußkörper 1 ist eine Nut 2 elngegossen. Dle Nutenflanken 3, 3' weisen Löcher 4,4' auf, die beispielhaft als Sacklöcher dargestellt sind. Dleses bedeutet, daß zwischen Nut 2 und den Jeweiligen Löchern 4,4' beim Giessen dünne Wandflächen verblleben sind. Während des Einpressens des Rohrheizkörpers 5 In die Nut 2 unter hohem Druck dringt Materlal der Rohrheizkörperummantelung 6 In die Löcher 4,4' . Nach dem Einpressen liegt die Ummantelung 6 satt an der Wandung der Nut 2 an. Der während des Einpressens in die Löcher 4,4'gedrungene Werkstoff behält seine Verformung bei und haltert dadurch den Rohrheizkörper 5 In der Nut 2.A groove 2 is cast in the cast body 1. The groove flanks 3, 3 'have holes 4,4', which are shown by way of example as blind holes. Dleses means that between groove 2 and the respective holes 4,4 'thin when pouring Wall surfaces fade away. While the tubular heater 5 is being pressed into the Groove 2 under high pressure penetrates material of the tubular heater casing 6 into the holes 4,4 '. After pressing in, the casing 6 lies snugly against the wall of the groove 2 at. The material that penetrated into the holes 4, 4 ′ during the pressing retains its Deformation and thereby holds the tubular heating element 5 in the groove 2.
Dle Löcher 4,4' lassen slch mit der Herstellung des Gußkörpers 1 sehr einfach herstellen. Das Gießwerkzeug welst im Berelch der Löcher Stempel auf, die beliebig gestaltet sein können. Dabei ist es nicht erforderlich, daß die Lochstempel während des GleBvorganges satt am Nutwerkzeug anllegen. Etwalge hierdurch entstehende dünne Flächen, die die Löcher zur Nut hin verschließen, wirken slch während des Elnpressens vorteilhaft aus. Elne unerwünschte, den Mantel des Heizkörpers möglicherweise verletzende Gradbildung im Berelch der Löcher wird slcher vermieden. Nlcht zuletzt ist von besonderem Vorteil, daß der bisher erforderliche Arbeitsschritt der blelbenden Verformung der Nutränder völlig überraschend entfallen kann, ohne daß die Verbindung von Gußkörper 1 und Heizkörper 5 nachteilig beeinträchtigt wird.The holes 4, 4 'leave the same with the production of the cast body 1 easy to manufacture. The casting tool welst in the area of the holes stamp on the can be designed in any way. It is not necessary that the punch Lean against the grooving tool during the gluing process. Etwalge resulting from this thin surfaces that close the holes towards the groove are effective during the Elnpressens advantageous. Elne unwanted, possibly the jacket of the radiator injurious degrees in the area of the holes are avoided. Not last is of particular advantage that the previously required step of blinding Deformation of the groove edges can surprisingly be omitted without the connection of cast body 1 and radiator 5 is adversely affected.
