Abstract
Schweißstromquelle zum Kondensator-Entladungsschweißen, dadurch gekennzeichnet, dass die Schweißstromquelle (2) zwei oder mehr steuerbare Stromquellenmodule (3, 4) aufweist.Welding power source for capacitor discharge welding, thereby characterized in that the welding power source (2) has two or more controllable current source modules (3, 4).
Description
Die Erfindung betrifft eine Schweißstromquelle zum Kondensator-Entladungsschweißen mit den Merkmalen im Oberbegriff des Hauptanspruchs.The The invention relates to a welding power source for capacitor discharge welding with the features in the preamble of the main claim.
Derartige Schweißstromquellen sind aus der Praxis bekannt. Sie enthalten einen Kondensator oder eine Kondensatorbatterie, die über eine Ladeeinrichtung elektrisch aufgeladen wird und sich unter Einwirkung einer Zündeinrichtung bei Bedarf entlädt und einen kurzzeitigen Stromimpuls zum Schweißen abgibt. Bei solchen Stromquellen bestehen nur wenig Einflussmöglichkeiten zur Gestaltung des Impulses und des Schweißstroms. Außerdem muss für jeden Stromimpuls die Ladezeit des Kondensators abgewartet werden, wodurch ein zeitlicher Mindestabstand der Stromimpulse vorgegeben ist.such Welding power sources are known from practice. They contain a capacitor or a capacitor bank that over a charging device is electrically charged and under the action an ignition device if necessary unloads and emits a momentary current pulse for welding. For such power sources There are only a few possibilities for influence for the design of the pulse and the welding current. In addition, for each current pulse wait for the charging time of the capacitor, creating a temporal Minimum distance of the current pulses is specified.
Es ist Aufgabe der vorliegenden Erfindung, eine verbesserte Schweißstromquelle aufzuzeigen.It Object of the present invention, an improved welding power source show.
Die Erfindung löst diese Aufgabe mit den Merkmalen im Hauptanspruch. Die Mehrfachanordnung und der Verbund eigenständig steuerbarer Stromquellenmodule hat verschiedene Vorteile. Einerseits können die Stromquellenmodule in der gewünschten Reihenfolge und mit wählbaren zeitlichen Abständen gezündet und entladen werden. Die Schweißstromquelle kann dadurch innerhalb kürzerer Zeiten als bisher Stromimpulse abgeben und wiederholen. Die Stromimpulse können sich auch überlappen. Durch eine frei steuerbare und wählbare Pulsfolge kann gezielter auf die Schweißprozesse und/oder Begleitprozesse Einfluss genommen werden. Z.B. kann mit zusätzlichen Stromimpulsen ein Vorwärmen und/oder Nachwärmen der Schweißstelle erzielt werden.The Invention solves this task with the features in the main claim. The multiple arrangement and the composite independently controllable power source modules has several advantages. On the one hand can the power source modules in the desired order and with selectable time intervals ignited and unloaded. The welding power source can thereby within shorter Give off times as before and repeat current pulses. The current pulses can also overlap. Through a freely controllable and selectable pulse sequence can be more focused on the welding processes and / or Accompanying processes are influenced. For example, can with additional Power pulses preheat and / or reheating the weld be achieved.
Die Stromquellenmodule und die Stromimpulse können gleiche oder unterschiedliche Leistungen haben. Dies bietet weitere Einflussmöglichkeiten auf die Schweiss- und/oder Begleitprozesse.The Power source modules and the current pulses may be the same or different Have benefits. This offers further possibilities of influencing the welding and / or accompanying processes.
Durch die modulare Ausbildung der Kondensatorentladungsstromquelle können zeitlich versetzte Lade- und Schweißzyklen der verschiedenen Stromquellenmodule erzielt werden. Zudem lässt sich der Stromverlauf des Schweißstroms gezielt beeinflussen, z.B. durch zeitlich versetzte und ggf. überschneidende Entladungen mehrerer Stromquellenmodule. Ferner lassen sich unterschiedliche Schweißnester mit einer gemeinsamen Schweißstromquelle versorgen.By the modular design of the capacitor discharge power source can be timed staggered loading and welding cycles the various power source modules are achieved. In addition, can be the current profile of the welding current specifically affect, e.g. by staggered and possibly overlapping Discharges of multiple power source modules. Furthermore, different weld nests can be used with a common welding power source supply.
Die modulare Schweißstromquelle kann unterschiedlich ausgebildet sein. Die Stromquellenmodule können z.B. an eine gemeinsame Energieversorgung parallel angeschlossen sein, was einen besonders geringen Bauaufwand mit sich bringt. Alternativ können die Stromquellenmodule eigene Energieversorgungen aufweisen, was größere Unabhängigkeiten für ihr Ladeverhalten bringen kann. Insbesondere kann die modulare Schweißstromquelle aus mehreren vernetzten, auf ein oder mehrere gemeinsame Ausgänge geschaltete und gemeinsam gesteuerte Einzelstromquellen bestehen.The modular welding power source can be designed differently. The power source modules may be e.g. be connected in parallel to a common power supply, which brings a particularly low construction cost. alternative can the power source modules have their own power supplies, which greater independence for their Can bring charging behavior. In particular, the modular welding power source from several networked, switched to one or more common outputs and jointly controlled single current sources exist.
