Description
Die Erfindung betrifft eine elektrische Widerstandsschweißmaschine, bei welcher das Blechpaket als Magnetgestell und Magnetanker ausgebildet ist. Das Wesen der Erfindung besteht darin, daß zwischen dem, als Magnetanker ausgebildeten Teil des Blechpaketes und dem schwingbaren Stromleiter eine Feder eingeschal-' tet ist, mittels welcher der Schweißdruck unabhängig von der Zugkraft des Magnetankers ίο regelbar ist.The invention relates to an electrical resistance welding machine, in which the laminated core is designed as a magnet frame and magnet armature. The essence of the invention consists in that between that, designed as a magnet armature part of the laminated core and the oscillating current conductor a spring is switched on, by means of which the welding pressure is independent can be regulated by the tensile force of the armature ίο.
Es ist bereits bekannt, bei elektrischen Schweißmaschinen üblicher Art Druckfedern zu verwenden, die in ihrer Spannung regelbar sind. Demgegenüber bietet die Regelung der Feder in Verbindung mit der Ausgestaltung des Blechpaketes als Magnetgestell und Magnetanker den Vorteil, den Schweißdruck unabhängig von der Schweißstromstärke auf die Werkstücke einwirken zu lassen.It is already known to apply compression springs to electrical welding machines of the usual type use the voltage that can be regulated. In contrast, the regulation of the spring offers in connection with the design of the laminated core as a magnet frame and magnet armature Advantage of the welding pressure acting on the workpieces regardless of the welding current allow.
so Auf der Zeichnung ist eine Ausführungsform der Erfindung schematisch dargestellt.so on the drawing is an embodiment of the invention shown schematically.
α bezeichnet den Eisenkern bzw. das Blechpaket,
b den als Magnetanker ausgebildeten Teil des Eisenkernes, schwingbar gelagert im Transformatorgehäuse,
c die Sekundärwindung in bekannter Weise als Gehäuse ausgebildet, d einen
Hebel mit Anker b fest vereinigt und mit letzterem schwingbar angeordnet, e den schwingbaren
Sekundärstromleiter, f den feststehenden zweiten Stromleiter, g das Gestänge mit der bekannten
Druckfeder zur Übertragung der vom Magnetanker ausgehenden Kräfte in den schwingbaren
Arm e, h eine Schaltvorrichtung, zur Unterbrechung
des Primärstromes.
Die Abbildung zeigt den Erfindungsgegenstand in Tätigkeit gesetzt, was durch Schließen
des Primärstromes durch Schalter h bewirkt wurde. Die Betätigungsorgane hatten vordem
die punktierte Lage eingenommen. Der Kern a ist z. B. in U-Form und der Anker b als gerades
Stück zu denken. α denotes the iron core or the laminated core, b the part of the iron core designed as a magnet armature, mounted to oscillate in the transformer housing, c the secondary winding designed as a housing in a known manner, d a lever with armature b firmly combined and arranged to oscillate with the latter, e the oscillatable Secondary current conductor, f the fixed second current conductor, g the linkage with the known compression spring for transmitting the forces emanating from the magnet armature into the oscillating arm e, h a switching device for interrupting the primary current.
The figure shows the subject of the invention put into action, which was effected by closing the primary current through switch h . The actuating organs had previously assumed the dotted position. The core a is z. B. to think in U-shape and the anchor b as a straight piece.
Die Erfindung soll sich auch auf entsprechende Einrichtungen für Lot-, Glüh- und dergleichen Zwecke beziehen.The invention is also intended to apply to corresponding devices for soldering, annealing and the like Purposes.
Es ist nicht stets erforderlich, daß der ganze Querschnitt des Eisenkernes durch den Anker b unterbrochen wird, letzterer kann ebensogut entsprechend dem Bedarf an mechanischer Kraft einen Teil des Eisenkernquerschnittes in Anspruch nehmen.It is not always necessary for the entire cross-section of the iron core to be interrupted by the armature b ; the latter can just as well take up part of the iron core cross-section according to the need for mechanical force.
Bei Benutzung der Einrichtung für Stumpfschweißmaschinen tritt an die Stelle der Punktiervorrichtung e, f eine beliebige Stauchvorrichtung. When using the device for butt welding machines, any upsetting device takes the place of the puncturing device e, f.
