Description
Die vorliegende Erfindung betrifft einen Induktor zum induktiven Härten von Werkstücken, umfassend mindestens zwei Induktorköpfe, die durch eine Stromleiteranordnung miteinander leitend verbunden sind und die verschiebbar zueinander angeordnet sind.The present invention relates to an inductor for the inductive hardening of workpieces, comprising at least two inductor heads, which are conductively connected to one another by a current conductor arrangement and which are arranged displaceable relative to one another.

Das der vorliegenden Erfindung zugrunde liegende Problem ist es, einen Induktor der eingangs genannten Art zur Verfügung zu stellen, der weniger aufwendig zu warten ist.The problem underlying the present invention is to provide an inductor of the type mentioned, which is less expensive to maintain.
Dieses Problem wird durch einen Induktor nach Patentanspruch 1 gelöst. Erfindungsgemäß ist vorgesehen, daß die Induktorköpfe lösbar mit der Stromleiteranordnung verbunden sind. Das Auswechseln der Induktorköpfe ist damit ohne Zerlegen des Induktors möglich.This problem is solved by an inductor according to claim 1. According to the invention it is provided that the inductor heads are detachably connected to the conductor arrangement. The replacement of the inductor heads is thus possible without disassembly of the inductor.
In einer bevorzugten Ausführungsform ist vorgesehen, daß der Induktor mindestens eine erste Induktorbaugruppe sowie eine zweite Induktorbaugruppe umfasst. Die Trennung in einzelne Baugruppen erleichtert die Montage und Demontage.In a preferred embodiment it is provided that the inductor comprises at least a first inductor assembly and a second inductor assembly. The separation into individual assemblies facilitates assembly and disassembly.
In einer bevorzugten Ausführungsform ist vorgesehen, daß die Induktorköpfe mit der Stromleiteranordnung mittels Schrauben verbunden sind. Die Entnahme der Induktorköpfe aus dem Induktor erfordert damit nur das Lösen von außen zugänglicher Schrauben.In a preferred embodiment it is provided that the inductor heads are connected to the conductor arrangement by means of screws. The removal of the inductor heads from the inductor thus requires only the release of externally accessible screws.
In einer bevorzugten Ausführungsform ist weiterhin vorgesehen, daß die Schrauben jeweils seitlich in die erste Induktorbaugruppe oder zweite Induktorbaugruppe einbringbar sind. Diese Maßnahme bietet den Vorteil, daß die Schrauben auch in Einbaulage des Induktors zugänglich sind.In a preferred embodiment it is furthermore provided that the screws can each be introduced laterally into the first inductor module or second inductor module. This measure has the advantage that the screws are accessible even in the installed position of the inductor.
In einer bevorzugten Ausführungsform ist weiterhin vorgesehen, daß die Stromleiteranordnung ein erstes Leiterelement sowie ein zweites Leiterelement umfaßt. Diese Ausgestaltung ermöglicht eine besonders leichte Montage und Demontage der Stromleiteranordnung.In a preferred embodiment, it is further provided that the current conductor arrangement comprises a first conductor element and a second conductor element. This embodiment enables a particularly easy assembly and disassembly of the conductor arrangement.
In einer bevorzugten Ausführungsform ist weiterhin vorgesehen, daß das erste und/oder das zweite Leiterelement über einen Kühlmittelkanal verfügt, der von einem Kühlmittel durchströmt werden kann. Eine Kühlung des Leiters verringert dessen elektrischen Widerstand und erhöht so durch geringere Verlustwärme den Gesamtwirkungsgrad. Weiterhin wird die Standzeit des Induktors erhöht.In a preferred embodiment, it is further provided that the first and / or the second conductor element has a coolant channel, which can be flowed through by a coolant. Cooling of the conductor reduces its electrical resistance and thus increases the overall efficiency through lower heat loss. Furthermore, the service life of the inductor is increased.
In einer bevorzugten Ausführungsform ist weiterhin vorgesehen, daß das Kühlmittel Wasser ist. Wasser hat günstige Wärmeübertragungseigenschaften und ist kostengünstig gegenüber anderen Kühlmitteln.In a preferred embodiment, it is further provided that the coolant is water. Water has favorable heat transfer properties and is inexpensive compared to other coolants.
In einer bevorzugten Ausführungsform ist weiterhin vorgesehen, daß das erste Leiterelement zwei in etwa parallel zueinander angeordnete Leiterbahnen umfaßt, die nicht leitend durch eine Verbindungsbrücke miteinander verbunden sind. Durch diese Maßnahme kann das erste Leiterelement aus vergleichsweise einfachen Grundbaugruppen hergestellt werden.In a preferred embodiment it is furthermore provided that the first conductor element comprises two conductor tracks which are arranged approximately parallel to one another and which are not connected to one another by a connecting bridge. By this measure, the first conductor element can be made of relatively simple basic assemblies.
In einer bevorzugten Ausführungsform ist weiterhin vorgesehen, daß das zweite Leiterelement mindestens zwei in etwa parallel zueinander angeordnete Leiterbahnen umfaßt, die nicht leitend durch ein Joch miteinander verbunden sind. Diese Maßnahme bietet den Vorteil, daß das zweite Leiterelement ebenfalls aus vergleichsweise einfachen Baugruppen aufgebaut werden kann.In a preferred embodiment, it is further provided that the second conductor element comprises at least two approximately parallel to each other arranged conductor tracks, which are not conductively connected to each other by a yoke. This measure has the advantage that the second conductor element can also be constructed of comparatively simple modules.
In einer bevorzugten Ausführungsform ist vorgesehen, daß der Induktor über ein Gehäuse verfügt, das aus mindestens einem ersten Teilgehäuse und einem zweiten Teilgehäuse besteht. Durch die zumindest teilweise Kapselung der Baugruppen des Induktors werden diese vor Beschädigungen sowie vor Verschmutzung geschützt. In a preferred embodiment it is provided that the inductor has a housing which consists of at least a first sub-housing and a second sub-housing. Due to the at least partial encapsulation of the modules of the inductor they are protected from damage and contamination.
In einer bevorzugten Ausführungsform ist weiterhin vorgesehen, daß das Gehäuse aus Aluminium besteht. Ein derartiges Gehäuse ist vergleichsweise kostengünstig und leicht spanend zu bearbeiten.In a preferred embodiment, it is further provided that the housing consists of aluminum. Such a housing is relatively inexpensive and easy to machine.
