Description
F i g. 2 eine Seitenansicht der Spule nach F i g. 1, gesehen in Richtung des Pfeiles A, F i g. Figure 2 is a side view of the spool of Figure 2. 1, seen in the direction of arrow A,
F i g. 3 eine Seitenansicht der Spule nach F i g. 1, gesehen in Richtung des Pfeiles B, F i g. 3 is a side view of the spool of FIG. 1, seen in the direction of arrow B,
F i g. 4 eine Schnittansicht längs der Linie C-C in Fig. 1,F i g. 4 shows a sectional view along the line CC in FIG. 1,
F i g. 5, 6, 7 und 8 Darstellungen entsprechen den F i g. 1 bis 4 einer weiteren, mittels eines erfindungsgemäßen Formwerkzeuges hergestellten Spule, deren Stirnwandungen unterschiedliche Durchbrechungen aufweisen.F i g. 5, 6, 7 and 8 representations correspond to FIGS. 1 to 4 of another, by means of an inventive Form tool produced coil, the end walls of which have different openings exhibit.
In F i g. 1 bis 4 sind für ein erstes Beispiel eine mittels des Formwerkzeugs gefertigte Spule die hohle Nabe 1 und die beiden parallelen Stirnwandungen 2, die scheibenförmig ausgebildet sind und deren Durchmesser je nach Verwendungszweck der Spule verschieden ist, dargestellt. Die Durchbrechungen in den Stirnwandungen bzw. die Rippen 10 werden mittels zweier Kerne 3-4 und 6 ausgebildet. Der mit dem Formteil fest verbundene Kern 3-4 besteht aus einem Zapfen 3 mit zwei diametral gegenüberliegenden Segmenten 4. Der mit dem anderen Formteil fest verbundene Kern 6 weist zwei diametral gegenüberliegende Segmente auf, die auf dem Zapfen 3 zwischen den Segmenten 4 des ersten Kerns verschieblich angeordnet sind. Zwischen den Segmenten der beiden Kerne befinden sich Zwischenräume, die zur Herstellung der Rippen 10 dienen. Die freien Enden der Kernteile 4 und 6 liegen in der Ebene der Innenfläche der jeweiligen Stirnwandung 2.In Fig. 1 to 4, for a first example, a coil manufactured by means of the molding tool is the hollow one Hub 1 and the two parallel end walls 2, which are disc-shaped and their Diameter is different depending on the intended use of the coil, shown. The breakthroughs in the end walls or the ribs 10 are formed by means of two cores 3-4 and 6. The one with the molded part firmly connected core 3-4 consists of a pin 3 with two diametrically opposed Segments 4. The core 6 firmly connected to the other molded part has two diametrically opposite opposite segments on the pin 3 between the segments 4 of the first core are arranged displaceably. There are gaps between the segments of the two cores, which are used to produce the ribs 10. The free ends of the core parts 4 and 6 are in the plane of the inner surface of the respective end wall 2.
In der Ausführungsform nach F i g. 5 bis 8 weist der eine Kern einen Zapfen 7 mit drei Segmenten 8 auf, die in gleich großen Winkelabständen voneinander angeordnet sind und mit dem zweiten Kern, der vier Segmente 9 besitzt, zusammenwirkt. In der einen Stirnwandung wird daher eine Durchbrechung mit vier Verzahnungen gebildet, während die Durchbrechung der anderen Stirnwandung drei Verzahnungen aufweist.In the embodiment according to FIG. 5 to 8 points one core has a pin 7 with three segments 8, which are angularly spaced from one another at the same size are arranged and with the second core, which has four segments 9, cooperates. In the an end wall is therefore formed an opening with four teeth, while the opening the other end wall has three teeth.
