Robert Bosch Akt.-Ges. in Stuttgart Auf Metall verankerter Preßkörper aus KunstpreßmasseRobert Bosch Akt.-Ges. In Stuttgart, anchored to metal anchored pressed body made of synthetic molding compound

Patentiert im Deutschen Reiche vom 6. Mai 1933 abPatented in the German Empire on May 6, 1933

Während es ohne weiteres möglich ist, Metallgegenstände, wie z. B. Bolzen, Buchsen o. dgl., in Kunstpreßmasse, wie Gummi, Kunstharz usw., einzubetten, bereitet es Schwierigkeiten, Hohlräume innen mit der Kunstpreßmasse auszukleiden, weil diese beim Abkühlen stärker schrumpft als das Metall und sich darum in der Schrumpfrichtung vom Metallkörper ablöst.While it is readily possible to use metal objects such as B. bolts, bushings o. The like., In synthetic molding compound, such as rubber, synthetic resin, etc., embed it, it is difficult, cavities inside with the Line synthetic molding compound because it shrinks more than the metal when it cools and therefore separates from the metal body in the direction of shrinkage.

Dieser Nachteil wird gemäß der Erfindung dadurch vermieden, daß die an sich bekannten Viorsprünge an dem einen der zu verbindenden Teile (Metall und Kunstpreßmasse), die in entsprechende Aussparungen des anderen Teiles greifen, im wesentlichen radial zum Schwerpunkt des Körpers nach innen oder außen gerichtet sind, um den beiden Stoffen ein voneinander unabhängiges Schrumpfen beim Abkühlen zu ermöglichen und beim fertigen Preßkörper eine feste Verbindung beider Stoffe zu gewährleisten.This disadvantage is avoided according to the invention in that the known per se Four jumps on one of the parts to be connected (metal and synthetic molding compound), which engage in corresponding recesses in the other part, essentially radially to the The body's center of gravity is directed inwards or outwards to the two fabrics to enable independent shrinkage during cooling and a firm connection in the finished pressed body to ensure both substances.

In der Zeichnung sind Ausführungsbeispiele des Erfindungsgegenstandes dargestellt. Es zeigtExemplary embodiments of the subject matter of the invention are shown in the drawing. It shows

Abb. ι einen hülsenförmigen Preß-körper im Längsschnitt,Fig. Ι a sleeve-shaped pressed body in Longitudinal section,

Abb. 2 einen Schnitt nach der Linie 11-11 in der Abb. 1,Fig. 2 a section along the line 11-11 in Fig. 1,

Abb. 3 einen Schnitt durch eine geänderte Ausführungsform nach der Linie III-III in der Abb. 1 undFig. 3 is a section through a modified embodiment along the line III-III in of Fig. 1 and

Abb. 4 einen halbkugelförmigen Preßkörper im Querschnitt.Fig. 4 shows a hemispherical compact in cross section.

Der in den Abb. 1 und 2 dargestellte Preßkörper besteht aus einer Hülse α aus Isolierstoff, wie Kunstharz, in die ein Metallring b eingebettet ist. An dessen beiden Stirnseiten stehen radial gerichtete, keilförmig abgeschrägte Rippen c hervor, durch die die Hülse α und der Ring b miteinander verankert sind.The pressed body shown in Figs. 1 and 2 consists of a sleeve α made of insulating material, such as synthetic resin, in which a metal ring b is embedded. Radially directed, wedge-shaped beveled ribs c protrude from its two end faces, through which the sleeve α and the ring b are anchored to one another.

Da beim Abkühlen nach dem Pressen der Isolierkörper α stärker zusammenschrumpft als der Metallring b, hat sich zwischen beiden ein ringförmiger Luftspalt ο gebildet. Trotzdem kann sich im fertigen Zustand der Ring nicht auf der Hülse verschieben, weil düie von der Ringmitte nach allen Richtungen jausgehenden Rippen c ein Verschieben oder Drehen des Ringes verhindern. Die keilförmige Abschrägung der Rippen c ist so gewählt, daß eine gute Passung erreicht wird. Since the insulating body α shrinks more than the metal ring b when it cools down after pressing , an annular air gap ο has formed between the two. Nevertheless, in the finished state, the ring cannot move on the sleeve because the ribs c extending from the center of the ring in all directions prevent the ring from moving or rotating. The wedge-shaped bevel of the ribs c is chosen so that a good fit is achieved.

Die Abb. 3 zeigt eine geänderte Ausführungsform, bei der an der Innenseite des Metallrings b radial gerichtete, schwach konische Zapfend angebracht sind. Diese Zapfen können entweder an Stelle der Rippen c verwendet werden oder zu den Rippen c noch hinzutreten.Fig. 3 shows a modified embodiment in which on the inside of the metal ring b radially directed, slightly conical pegs are attached. These pegs can either be used in place of the ribs c or in addition to the ribs c.

Der Isolierkörper kann auch eine andere, von einer Hülse abweichende Gestalt haben, z. B. die Form einer Kappe o. dgl.The insulating body can also have a different shape deviating from a sleeve, z. B. the shape of a cap o.
