Vorrichtung zum Umformen von ElektrodenkappenDevice for forming electrode caps

Die Erfindung betrifft eine Vorrichtung zum Umformen von Elektrodenkappen für die Widerstandsschweißtechnik.The invention relates to a device for forming electrode caps for resistance welding technology.

Elektroden für die Widerstandsschweißtechnik, die in Roboter- und Handschweißzangen eingesetzt werden, müssen in Abhängigkeit vom Verschleiß an den Kappen nachgearbeitet werden, um die Zuverlässigkeit und Festigkeit der Schweißpunkte zu gewährleisten. Insbesondere an Schweißrobotern mit hoher Schweißfolge und der gleichzeitigen Forderung nach guter Reproduzierbarkeit der Schweißverbindung, wie sie im Fahrzeugbau gestellt wird, ist eine Nachbearbeitung zur Urform der Elektrodenkappe von großer Bedeutung. Dafür werden bekannterweise Vorrichtungen eingesetzt, die in einer angetriebenen Fräseraufnahme eine Schneidplatte enthalten (DE 299 03 526 Ul). Ein Nachteil derartiger Vorrichtungen ist es, daß mit jeder Nachbearbeitung Material von der Elektrodenkappe abgetragen wird, so daß die Kappe an Volumen verliert. Zudem müssen die entstandenen Späne zuverlässig von der Quelle ihrer Entstehung während des Fräsvorganges nach außen abgeführt werden. Das erfordert besondere konstruktive Ausgestaltungen der Fräseraufnahme und eine Zusatzeinrichtung zum Ableiten der Späne.Electrodes for resistance welding technology, which are used in robot and hand welding guns, must be reworked depending on the wear on the caps in order to ensure the reliability and strength of the welding points. Reworking to the original shape of the electrode cap is particularly important for welding robots with a high welding sequence and the simultaneous requirement for good reproducibility of the weld joint, as is the case in vehicle construction. Devices are known to be used for this purpose which contain a cutting plate in a driven milling cutter holder (DE 299 03 526 Ul). A disadvantage of such devices is that material is removed from the electrode cap with each reworking, so that the cap loses volume. In addition, the chips created must be reliably removed from the source of their creation to the outside during the milling process. This requires special structural designs of the milling cutter holder and an additional device for removing the chips.

Aufgabe der Erfindung ist es, eine Vorrichtung zu entwickeln, die ein weitgehend spanloses Nacharbeiten der Urform der Elektroden an der Kappe ermöglicht.The object of the invention is to develop a device which enables a largely chip-free reworking of the original shape of the electrodes on the cap.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Vorrichtung aus einer elektrisch angetriebenen Aufnahme besteht, die als Formkopf ausgebildet ist, der eine horizontal angeordnete, nicht angetriebene Formwalze und beidseitig im Formkopf integrierte Lagerungen für die Formwalze aufweist, wobei die Kontur der Formwalze in ihrem Arbeitsbereich der angestrebten Kappengeometrie der zu bearbeitenden Elektrode entspricht.According to the invention, the object is achieved in that the device consists of an electrically driven holder which is designed as a forming head which has a horizontally arranged, non-driven forming roller and bearings for the forming roller integrated in the forming head on both sides, wherein the contour of the forming roller in its working area corresponds to the desired cap geometry of the electrode to be processed.

Aufbau und Wirkungsweise der erfindungsgemäßen Vorrichtung werden im folgenden anhand von Zeichnungen beispielhaft beschrieben.The structure and mode of operation of the device according to the invention are described below by way of example with reference to drawings.

Es zeigen:Show it:

Figur 1 einen Längsschnitt durch die VorrichtungFigure 1 shows a longitudinal section through the device

Figur 2 einen Schnitt durch die Vorrichtung in perspektivischer DarstellungFigure 2 shows a section through the device in perspective

Die in bekannter Weise elektrisch angetriebene Aufnahme ist als Formkopf 1 ausgebildet. Der Formkopf 1 enthält die in den Lagerungen 2 gelagerte, nicht angetriebene Formwalze Die Formwalze 3 entspricht in ihrer Kontur im Arbeits- bzw. Eingriffsbereich 4 der angestrebten Kappengeometrie.The holder, which is electrically driven in a known manner, is designed as a forming head 1. The forming head 1 contains the non-driven forming roller which is mounted in the bearings 2. The contour of the forming roller 3 in the working or engagement area 4 corresponds to the desired cap geometry.

Der Formkopf wird in Bewegung gesetzt und die Schweißektrodenkappen mittels Roboterzangen oder handgeführte Zangen paarweise (hier: oben und unten) in den Formkopf 1 eingeführt und fixiert. Die Formwalze 3 arbeitet an den Eingriffsflächen 4 die Konturen der Kappen i.w. spanlos nach. Die Formwalze 3 selbst kann während dieses Vorgangs in den Lagerungen 2 eine zusätzliche, durch den Kontakt mit der Elektrodenkappe ausgelöste Drehbewegung um ihre Längsachse ausführen.The forming head is set in motion and the welding electrode caps are inserted and fixed in pairs (here: top and bottom) into the forming head 1 using robot tongs or hand-held tongs. The forming roller 3 reworks the contours of the caps on the engagement surfaces 4 in a largely chip-free manner. During this process, the forming roller 3 itself can perform an additional rotary movement around its longitudinal axis in the bearings 2, triggered by contact with the electrode cap.

Die Vorrichtung kann je nach Erfordernis auch in anderen Lagen als der hier beschriebenen zum Einsatz kommen.Depending on requirements, the device can also be used in positions other than those described here.

Da die Konturen der Elektrodenkappen durch ein plastisches Fließen des Materials nachgearbeitet werden, tritt keine Volumenänderung an den Elektrodenkappen ein, die somit lange im Einsatz bleiben können.Since the contours of the electrode caps are reworked by plastic flow of the material, there is no change in volume of the electrode caps, which means they can remain in use for a long time.

Die erfindungsgemäße Vorrichtung gestattet ein wirtschaftliches und formgetreues spanloses Nacharbeiten der Urform von Elektrodenkappen von Schweißelektroden. Mit der Vorrichtung kann der gesamte Bereich der in der Widerstandsschweißtechnik angewandten Elektrodengrößen und Kappenformen nachgearbeitet werden.The device according to the invention allows economical and dimensionally accurate chipless reworking of the original shape of electrode caps of welding electrodes. The device can be used to rework the entire range of electrode sizes and cap shapes used in resistance welding technology.
