Description

Vorrichtung zum Einstanzen der Nuten in Blechstreifen elektrischer Maschinen Es sind bereits Vorrichtungen zum Einstanzen der Nuten in Blechstreifen, die laufend verformt werden, um hochkant aufgewickelte Ständer: oder Läuferblechpakete elektrischer Maschinen zu ergeben, bekanntgeworden. Bei den bekannten Verfahren erfolgt das Einstanzen der Zähne in den Blechstreifen und das Verformen bzw. Krümmen des Blechstreifens zwecks Aufwickehzs zeitlich nacheinander. Hierdurch ergeben sich Ungenauigkeiten, die die Brauchbarkeit des fertiggewikkelten Ständer- oder Läuferblechpaketes beeinträchtigen.Device for punching the grooves in sheet metal strips electrical Machines There are already devices for punching the grooves in sheet metal strips, which are continuously deformed to form upright wound uprights: or laminated rotor stacks to result in electrical machines, became known. With the known methods the teeth are punched into the sheet metal strip and deformed or curved of the sheet metal strip one after the other for the purpose of winding up. This results in Inaccuracies that affect the usefulness of the finished stator or rotor core affect.

Gemäß der Erfindung werden diese Nachteile dadurch vermieden, daß man die Stanzvorrichtung so ausbildet, daß sie selbst zugleich die Blechstreifen verformt. Die Stanzvorrichtung wird hierzu vorteilhafterweise mit einer Presse zum Verformen der Blechstreifen durch Einkerben versehen.According to the invention, these disadvantages are avoided in that the punching device is designed in such a way that it is also the sheet metal strip itself deformed. The punching device is advantageously used for this purpose with a press Deform the sheet metal strips by notching.

Auf der Zeichnung ist ein Ausführungsbeispiel angegeben.An exemplary embodiment is shown in the drawing.

Die Fig. i bis 3 veranschaulichen schematisch die Bearbeitung des Blechstreifens gemäß der Erfindung in drei verschiedenen Ansichten.Figs. I to 3 illustrate schematically the processing of the Sheet metal strip according to the invention in three different views.

Fig. q. veranschaulicht einen fertigbearbeiteten Blechstreifen.Fig. Q. illustrates a finished sheet metal strip.

Fig. 5 zeigt einen Schnitt nach der Linie II-II der Fig. q. und Fig. 6 einen Schnitt nach der Linie III-III der Fig. q..Fig. 5 shows a section along the line II-II of Fig. Q. and Fig. 6 a section along the line III-III of Fig. Q ..

Fig. 2 und 7 zeigen einen Blechstreifen, aus dem zwei Ständerblechpakete hergestellt werden. Von einer bekannten Vörratsrolle i' wird ein Blechstreifen 2' zwischen Walzen 3' und q.' hindurchgeführt und hierbei gestanzt und zugleich geformt. Hierzu besitzen die Walzen 3' und q.' die in Fig. 3 angedeutete Form. Mit der Mitte g' der Walzen werden die Nuten gestanzt, während die Enden io' der Walzen den Blechstreifen krümmen, indem sie Einkerbungen 2 (Fig. q) in ihn einpressen. Diese Einkerbungen legen sich, wie man aus den Fig. 5 und 6 ersieht, beim Bilden des Blechpaketes aufeinander.2 and 7 show a sheet metal strip from which two stator laminations getting produced. A sheet metal strip 2 'is taken from a known supply roll i' between rollers 3 'and q.' passed through and punched and formed at the same time. For this purpose, the rollers 3 'and q.' the shape indicated in FIG. 3. With the middle g 'of the rollers the grooves are punched, while the ends io' of the rollers the sheet metal strips bend by pressing notches 2 (Fig. q) into it. These notches As can be seen from FIGS. 5 and 6, lie on top of one another when forming the laminated core.

Der Blechstreifen wird gemäß Fig. 2, 3 und 7 in bekannter Weise so gestanzt, daß zwei mit Nuten i versehene Streifen 5, 6 bzw. 5', 6' entstehen, die sich in bekannter Weise voneinander trennen und auf Trommeln 7', 8' aufgewickelt werden, so daß zwei Ständerblechpakete entstehen.The sheet metal strip is shown in FIGS. 2, 3 and 7 in a known manner punched that two grooves i provided with strips 5, 6 and 5 ', 6' arise, the separate from one another in a known manner and wound onto drums 7 ', 8' so that two stator stacks are created.
