Verfahren zum Herstellen von PreßstüffkollektorenProcess for the production of Preßstüffkollectors

409851 /0 184409851/0 184

Die Erfindung betrifft ein Verfahren zum Herstellen von Preßstoff kollektor en aus einem hohlzylinderförmigen Metallkörper, der mit einer der vorgesehenen Kollektorteilung entsprechenden Anzahl von axial ausgerichteten Gruppen von einwärts weisenden Verankerungselementen versehen ist/ wobei der Metallkörper in einer Preßform mit einem Isolierstoff zu einem Kollektorrohling gejreßt und später in die einzelnen Lamellen zerteilt wird.The invention relates to a method for producing molding material collectors made of a hollow cylindrical metal body, the number of axially aligned groups of inward-facing groups corresponding to the intended collector pitch Anchoring elements is provided / wherein the metal body is in a compression mold with an insulating material to form a collector blank is pressed and later divided into the individual lamellae.

Kleine Kollektoren werden häufig nicht aus einzelnen Lamellen zusammengesetzt, sondern man geht von einem hohlzylinderförmigen Metallkörper aus, der mit einer der vorgesehenen Kollektorteilung entsprechenden Anzahl von axial ausgerichteten Gruppen von einwärts weisenden Verankerungselementen versehen ist., Diese Metallkörper werden entweder aus Kupferprofilrohr gefertigt, das beispielsweise in einem Strangpreß- und Ziehverfahren profiliert worden ist und von dem die einzelnen Metallkörper in entsprechender Länge abgetrennt v/erden, oder sie werden aus einem Profilband gefertigt, das aus einem bandförmigen Vormaterial durch Walzen profiliert worden ist und von dem jeweils der Umfangslänge des Kollektors entsprechende Abschnitte abgetrennt und zu den hohlzylinderförmigen Metallkörpern gerollt werden. Bei der Herstellung von Kollektoren mit Wickelhaken ist das letztgenannte Verfahren wirtschaftlicher, weil der Abschnitt des Metallkörpers, der die Wickelhaken aufweist, beim Walzen durch entsprechende Materialverdrängung materialsparend hergestellt werden kann, wohingegen er bei der Verwendung von Kupferprofilrohr aus einem entsprechenden Längenabschnitt dieses Rohres durch Materialzerspanung hergestellt v/erden müßte.Small collectors are often not composed of individual lamellae, but rather a hollow cylinder-shaped one Metal body made of axially aligned with a number of axially aligned ones corresponding to the intended collector pitch Groups of inwardly facing anchoring elements is provided., These metal bodies are either made of copper profile tube that has been profiled, for example, in an extrusion and drawing process and from which the individual metal bodies are separated in the appropriate length, or they are made from a profile strip, which has been profiled from a strip-shaped starting material by rolling and each of the circumferential length corresponding sections of the collector are separated and rolled to form the hollow cylindrical metal bodies. In the preparation of of collectors with winding hooks, the latter method is more economical because the section of the metal body, which has the winding hooks, produced in a material-saving manner during rolling by appropriate material displacement can be, whereas when using copper profile pipe from a corresponding length of this pipe produced by material machining.

Die hohlzylinderförmigen Metallkörper werden in einer Preßform mit einem dafür üblichen Isolierstoff zu einem Kollektorrohling gepreßt, der in der Regel bereits die AufnahmebohrungThe hollow cylindrical metal bodies are in a press mold with a customary insulating material to form a collector blank pressed, which usually already has the mounting hole

enthält. Bei diesen Kollektorrohlingen wird der ringförmige Metallkörper zwischen den Längsrippen mit den Verankerungselementen durch Aufsägen in die einzelnen Lamellen zerteilt.contains. In these collector blanks, the ring-shaped metal body is between the longitudinal ribs with the anchoring elements cut into the individual lamellae by sawing.

Bei Erkalten des gepreßten Kollektorrohlings ist der Schwund des Isolierstoffkörpers größer als der des Metallkörpers. Dadurch löst der Isolierstoffkörper sich etwas von dem Metallkörper, so daß nach dem Zerteilen des Metallkörpers in die einzelnen Lamellen diese nicht mehr festWhen the pressed collector blank cools down, the shrinkage of the insulating body is greater than that of the metal body. As a result, the insulating body is somewhat detached from the metal body, so that after the metal body has been divided into the individual lamellae, these are no longer fixed

in dem Isolierstoffkörper verankert sind. Bei der Verwendung eines adhäsiven Isolierstoffes ist zwar die Gefahr des Lockerwerdens der Lamellen verringert, dafür tritt aber in dem Isolierstoffkörper eine von der Bohrungsseite des Kollektors ausgehende Rißbildung auf. Beide Erscheinungen beeinträchtigen die Festigkeit und die Dauerhaftigkeit des fertigen Kollektors in erheblichem Maße. Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zum Herstellen von Preßstoffkollektoren anzugeben, bei dem diese ungünstigen Erscheinungen nicht auftreten.are anchored in the insulating body. There is a risk when using an adhesive insulating material the loosening of the lamellas is reduced, but there is one in the insulating body from the bore side of the Outgoing collector cracking. Both phenomena affect the strength and durability of the finished product Collector to a considerable extent. The invention is therefore based on the object of a method for producing compressed material collectors indicate where these unfavorable phenomena do not occur.

Diese Aufgabe ist bei einem Verfahren mit den eingangs genannten Verfahrensschritten dadurch gelöst, daß das Zerteilen des Metallkörpers des Kollektorrohlings vor dem Erkalten desselben durchgeführt wird. Dadurch liegt also während des Erkaltens des Kollektors kein in Umfangsrichtung geschlossener Metallkörper mehr vor, so daß die nunmehr voneinander getrennten Einzellamellen dem beim Erkalten des Isolierstoffkörpers auftretenden Schwund in mialer Richtung ohne weiteres folgen können. Dadurch wiederum wird vermieden, daß sich die Lamellen lockern oder daß im Isolierstoffkörper Risse auftreten.In a method with the method steps mentioned at the outset, this object is achieved in that the metal body is divided the collector blank is carried out before it cools down. This means that while the Collector is not a metal body closed in the circumferential direction more before, so that the now separated individual lamellae occur when the insulating body cools down Shrinkage in the mial direction can easily follow. This in turn prevents the slats from loosening or that cracks appear in the insulating material body.

Das vorstehend beschriebene Verfahren kann in vorteilhafter Weise noch dadurch begünstigt werden, daß der Metallkörper des Kollektorrohlings vor dem Zerteilen in die Lamellen durch ein KühlmittelThe method described above can be favored in an advantageous manner that the metal body of the collector blank before cutting into the lamellae by a coolant

abgeschreckt wird. Dadurch wird der im preßwarmen Zustand mit dem Isolierstoffkörper innig verbundene Metallkörper auf den nicht abgeschreckten und dadurch sich langsamer abkühlenden Isolierstoffkörper zusätzlich aufgeschrumpft. Dadurch wird die Verankerung der unmittelbar darauf voneinander getrennten Lamellen im Isolierstoffkörper noch weiter verbessert.is deterred. As a result, the metal body is intimately connected to the insulating body in the hot-pressed state It is additionally shrunk onto the insulating body, which has not been quenched and therefore cools down more slowly. This is how the anchoring of the lamellae, which are immediately separated from one another, in the insulating material body improved even further.

Für das im allgemeinen an das Zerteilen des Metallkörpers in die einzelnen Lamellen anschließende Tempern des Preßstoffkollektors ist das Verfahren gemäß der Erfindung ebenfalls von Vorteil, weil eine Lockerungen zwischen den Lamellen und dem Isolierstoffkörper und/oder eine Rißbildung im Isolierstoffkörper weder aufgetreten noch eingeleitet worden ist, was sich sonst beim Tempern des gesamten Kollektors verschlimmern könnte.For the tempering of the pressed material collector, which generally follows the cutting of the metal body into the individual lamellae the method according to the invention is also advantageous because there is looseness between the lamellae and the insulating body and / or cracking in the insulating body has neither occurred nor initiated, which would otherwise be exacerbated by annealing the entire collector could.
