Description

Folgeschnitt zum Stanzen von Ständer-und Läuferblechen für Elektromotoren Gegenstand der Erfindung ist ein Folgeschnitt zum Stanzen von Ständer- und Läuferblechen für Elektromotoren.Follow-up cut for punching stator and rotor sheets for electric motors The invention relates to a subsequent cut for punching stator and rotor sheets for electric motors.

Um Ein- oder Mehrphasenmotoren verschiedenen Anlaufbedingungen anpassen zu können,ist bekanntlich die Wahl verschiedener Werkstoffe für den Kurzschlusskäfig allein in vi.elen Fällen nicht ausreichend. Häufig ist es notwendig, unter Beibehaltung aller übrigen Abmessungen auch noch den Querschnitt und die Höhe der Läufernuten zu ändern. Soweit nurl Läufer mit verschiedenen Nutenhöhen und Querschnitten erforderlich sind, war es bisher notwendig mehrere Folgeschnitte zu verwenden, die sich nur in den Abmessungen der Läufernuten unterschieden haben.To adapt single or multi-phase motors to different starting conditions is known to be able to choose different materials for the squirrel cage alone not sufficient in many cases. Often times it is necessary while maintaining all other dimensions also include the cross-section and the height of the rotor grooves to change. Insofar as only sliders with different groove heights and cross-sections are required it was previously necessary to use several subsequent cuts that were only in have differentiated the dimensions of the rotor slots.

Aufgabe der Erfindung war, ein Stanzwerkzeug so auszubilden, dass mit einem Folgeschnitt Bleche mit verschiedenen Läufernuten herstellbar sind, damit also Werkzeugkosten und Rüstzeiten gesenkt werden können. Erfindungsgemäß wird dies dadurch erreicht, dass bei einem Folgeschnitt zum Stanzen von Ständer- und Läuferblechen für Elektromotoren die Läufernutstempel in eine äussere und eine innere Hälfte geteilt und in zwei verschiedenen Stanztakten angeordnet sind. Vorteilhafterweise wird dabei die innere Hälfte der Läufernutstempel in dem Takt angeordnet, welcher die Ständernutstempel aufweist.Das Schnittwerkzeug kann dabei wahlweise entweder so ausgebildet sein, dass die inneren Hälften der Läufernutstempel zurückziehbar sind oder es können die Stirnflächen dieser Stempel gegenüber den übrigen um einen geringen Betrag zurückgeschli-#-fen sein.The object of the invention was to design a punching tool so that with a subsequent cut sheets with different runner grooves can be produced so that so tool costs and set-up times can be reduced. According to the invention this is achieved by the fact that with a subsequent cut for punching stator and rotor sheets For electric motors, the rotor slot punch is divided into an outer and an inner half and are arranged in two different punching cycles. It is advantageous here the inner half of the Läufernutstempel arranged in the cycle, which the Ständutstempel The cutting tool can either be designed so that the inner halves of the rotor groove punches are or can be retractable the end faces of these punches are reduced by a small amount compared to the others be.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Die bei den einzelnen Takten stattfindenden Stanzungen sind durch stärkere Striche hervorgehoben. Werden In einer bevorzugten Ausführung die Stirnflächen der inneren Läufernutstempel gegenüber den üb- rigen um einen geringen Betrag zurückgeschllffen, so werden bei einem. kurzen Stanzhub nur die äusseren Hälften der Läufernuten gestanzt, während bei einem entsprechend längeren Stanzhub auch die Inneren Hälf- ten der Läufernuten ausgestanzt werden.An exemplary embodiment of the subject matter of the invention is shown in the drawing. The punchings that take place in the individual bars are highlighted by thicker lines. If, in a preferred embodiment, the end faces of the inner rotor groove punches are drawn back by a small amount compared to the others, then in one case. For a short punching stroke, only the outer halves of the slider slots are punched, while with a correspondingly longer punching stroke, the inner halves of the slider slots are also punched out.
