Zusatz zum Patente 224879 vom 21. September 1909.Addendum to patent 224879 of September 21, 1909.
Patentiert im Deutschen Reiche vom 1. Januar 1910 ab. Längste Dauer: 20. September 1924.Patented in the German Empire on January 1, 1910. Longest duration: September 20, 1924.
Bei dem in der Patentschrift 224879 beschriebenen elektrischen Schweißverfahren, bei welchem die zur Schweißung notwendige Energie aus einer Gleichstromquelle entnommen wird, kann die Energiemenge, welche in den Schweißstücken pro Sekunde in Wärme umgesetzt wird, bekanntlich dadurch geregelt werden, daß die Kapazität der verwendeten Kondensatoren verändert wird. Die Veränderung von Kondensatoren stößt aber auf erhebliche praktische Schwierigkeiten. Es gibt zwar verhältnismäßig leicht regulierbare Kondensatoren. Diese besitzen aber zu geringe Kapazität, um bei vorliegendem VerfahrenIn the electrical welding process described in patent specification 224879, at from which the energy required for welding is taken from a direct current source is known, the amount of energy, which is converted into heat in the weldments per second, can be regulated thereby that the capacitance of the capacitors used is changed. The change of capacitors, however, encounters considerable practical difficulties. There are relatively easily adjustable capacitors. However, these have too little capacity to be used in the present process
15. verwandt werden zu können, auch sind diese Kondensatoren, vom wirtschaftlichen Standpunkte betrachtet, wenig geeignet, da ihre Anschaffung mit erheblichen Kosten verbunden ist.15. These capacitors can also be used from an economic standpoint considered, not very suitable, as their acquisition is associated with considerable costs is.
Man kann außerdem die Schweißhitze bei bestimmten Arbeitsstücken dadurch regulieren, daß die Zeitdauer, in welcher die Arbeitsstücke eingeschaltet sind, verändert wird. Diese Regulierung ist aber nur in sehr engen Grenzen möglich, da für ein gegebenes Arbeitsstück immer eine bestimmte Dauer der Erhitzung annähernd beibehalten werden muß, wenn einerseits unnötiger Effektverbrauch und andererseits eine Verbrennung des Arbeits-Stückes mit Sicherheit vermieden werden soll.You can also regulate the welding heat for certain workpieces by that the length of time in which the work pieces are switched on is changed. However, this regulation is only possible within very narrow limits, since it is for a given piece of work always a certain duration of the heating must be approximately maintained if on the one hand unnecessary effect consumption and on the other hand, burning of the work piece is to be avoided with certainty.
Nach vorliegender Erfindung wird bei demAccording to the present invention is in the
in der Patentschrift 224879 beschriebenen Verfaliren eine sehr exakte Regulierung in weiten Grenzen dadurch erzielt, daß die Periodenzahl des durch die Arbeitsstücke fließenden Wechselstromes verändert wird.in the patent 224879 described a very precise regulation in wide limits achieved by the fact that the number of periods of the work pieces flowing alternating current is changed.
Der Effekt eines einzelnen Stromstoßes ist bei dem in Frage stehenden Verfahren im wesentlichen bestimmt durch die Größe des Kondensators und die Größe der Gleichstromspannung, welche zur Verwendung kommt; es ist daher bei diesem Verfahren möglich, die Schweißhitze dadurch zu regulieren, daß man die Anzahl der Stromstöße in der Zeiteinheit verändert, was durch Änderung der Tourenzahl des Stromwenders bzw. der Geschwindigkeit eines entsprechenden Schalters erreicht werden kann.The effect of a single rush current is in the method in question in essentially determined by the size of the capacitor and the size of the direct current voltage, which one is used; it is therefore possible in this method to regulate the welding heat by that the number of power surges in the unit of time is changed, which is achieved by changing the Number of revolutions of the commutator or the speed of a corresponding switch can be reached.
Der Stromwender wird in der Regel durch einen Elektromotor angetrieben. Die. Geschwindigkeit des Stromwenders kann daher durch Regulierung der Tourenzahl des Motors geändert werden. Für den Fall, daß -ein Nebenschlußmotor zur Anwendung kommt, kann die Tourenregulierung mit einfachen Mitteln in sehr weiten Grenzen durch Widerstandsänderüngen in dem Nebenschlußkreis des Motors vorgenommen werden.The commutator is usually driven by an electric motor. The. speed of the commutator can therefore by regulating the number of revolutions of the engine be changed. In the event that a shunt motor is used, the tour can be regulated with simple Averaging within very wide limits through resistance changes in the shunt circuit of the engine.
