Description
und 4,5 handelt es sich um zwei um etwa 180° versetzte Induktionsspulen 6, deren Windungen und/ oder Induktionsfeld ein zu bearbeitendes Werkstück 3 um je etwa 180° umfassen. Es besteht aber auch die in Fig. 3 angedeutete Möglichkeit, drei um etwa 120° versetzte Induktionsspulen 6 vorzusehen. Nicht besonders erläutert ist in den Zeichnungen, wie die einzelnen Induktionsspulen 6 geschaltet weiden können. Man entnimmt jedoch aus den Figuren unmittelbar, daß die einzelnen Induktionsspulen 6 sowohl einzeln an Stromversorgungsaggregate 7 angeschlossen als auch nach Art der Wicklungen des Stators eines Kurzschlußläufer-Elektromotors geschaltet werden können. Dabei mag es sich bei den Fig2 und4,5 um Zweiphasenstrom, bei der Ausführungsform nach Fig. 3 um Dreiphasenstrom han-and 4.5 are two offset by about 180 ° Induction coils 6, their turns and / or induction field a workpiece to be machined 3 to encompass approximately 180 ° each. But there is also the option indicated in FIG. 3, three to Provide induction coils 6 offset by about 120 °. Not particularly explained in the drawings, how the individual induction coils 6 can graze switched. However, one inferred from the figures immediately that the individual induction coils 6 are both individually connected to power supply units 7 and connected to the type of windings of the stator of a squirrel cage electric motor can be. 2 and 4.5 may be two-phase current in the embodiment according to Fig. 3 about three-phase current
Die Fig-4 und5 machen deuüich, daß die einzelnen Induktionsspulen 6 Windungen 8 aufweisen, d* in Achsrichtung des Stabmatenals3 einander überlappen, und zwar in Form einer einfachen Auf&cherung (Fig.4) oder auch in Form einer Verflechtung (FB?i5einer Elektro-Stauchmfschine kann das zu stauchende Stabmaterial 3 orthogonal zur Vorschubrichtung beim Stauchvorgang in die Beheizungseinrichtung 5 eingeführt und aus dieser auch wieder herausgenommen werden.FIGS. 4 and 5 make it clear that the individual induction coils have 6 turns 8, d * overlap one another in the axial direction of the rod material 3, namely in the form of a simple arrangement (FIG. 4) or in the form of an interweaving (F B? I 5 an electric upsetting machine, the rod material 3 to be upset can be introduced into the heating device 5 orthogonally to the feed direction during the upsetting process and can also be removed from it again.
