Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum aufeinanderfolgenden Härten der Lagerflächen von unterschiedlich dimensionierten Kurbelwellen von Brennkraftmaschinen mit Hilfe von zwei oder mehreren in senkrechten Ebenen beweglichen Induktoren.The invention relates to a device for successive hardening of the bearing surfaces of different sized crankshafts from Internal combustion engines using two or more in vertical planes movable inductors.
Derartige Vorrichtungen sind bekannt. Bei einer bekannten Ausführung gemäß DE 38 36 268 A1 ist der Induktor mit zugehörigem Transformator zu einer beweglichen Baueinheit verbunden. Es ist ferner schon vorgeschlagen worden, DE 38 42 808 A1, die zu einem Induktorsatz gehörenden Induktoren zur Anpassung an unterschiedliche Lagerabstände einer Kurbelwelle in Achsrichtung desselben gegeneinander verschieblich anzuordnen.Such devices are known. With a known Version according to DE 38 36 268 A1 is the inductor associated transformer to a movable unit connected. It has also been suggested DE 38 42 808 A1, which belong to an inductor set Inductors to adapt to different bearing distances a crankshaft in the same axial direction against each other to be moved.
Um die induktive Härtevorrichtung an unterschiedliche Kurbelwellentypen mit unterschiedlich dimensionierten Lagern anzupassen, mußte man bisher immer die Induktoren auswechseln. Die Induktoren haben nämlich Öffnungen für das teilweise Umfassen der im Querschnitt kreisförmigen Lagerflächen, die dem Lagerdurchmesser naturgemäß angepaßt sein müssen. To the inductive hardening device to different Crankshaft types with different dimensions Up to now, the inductors have always had to be adapted to bearings replace. The inductors have openings for partially encompassing the circular cross-section Storage areas that are naturally adapted to the bearing diameter have to be.
Die Induktoren sitzen als sogenannte reitende Induktoren auf den zu härtenden Lagerflächen und bewegen sich während des Umlaufs der zu härtenden Kurbelwelle auf einer Kreisbahn, die das Kurbellager beschreibt. Beim Härten der Kurbelwellenlager bleibt der Induktor dagegen während des Umlaufs der Kurbelwelle in seiner Lage ortsfest, weil die Kurbellager koaxial sind.The inductors sit as so-called riding inductors on the bearing surfaces to be hardened and move during the rotation of the crankshaft to be hardened a circular path that describes the crank bearing. At the However, the inductor remains hardening of the crankshaft bearings during the rotation of the crankshaft in its position stationary because the crank bearings are coaxial.
Der Erfindung liegt nun die Aufgabe zugrunde, das Umrüsten der induktiven Härtevorrichtung für Kurbelwellen zu erleichtern und insbesondere zu beschleunigen, damit beim Wechsel der Kurbelwellentype die Umrüstzeit verringert werden kann. Wie gesagt, mußten bisher die Induktoren ausgetauscht werden, wenn ein anderer Kurbelwellentyp zur Härtestation transportiert wurde. Dieser Induktorwechsel erforderte beträchtliche Zeit, weil er nicht nur elektrisch, sondern auch kühlmittelseitig angeschlossen ist. Beim Wechsel eines Induktors mußten also der elektrische Anschluß und der Kühlmittelanschluß abmontiert und nach Wechsel des Induktors wieder anmontiert werden. Dadurch ergaben sich beim Umrüsten der Härtevorrichtung erhebliche Totzeiten.The invention is based on the object Converting the inductive hardening device for crankshafts to facilitate and in particular to accelerate the changeover time when changing the crankshaft type can be reduced. As I said, so far they have had to Inductors are exchanged if another Crankshaft type was transported to the hardening station. This inductor change took considerable time because it's not only electric, but also is connected on the coolant side. When changing one So the inductor had the electrical connection and Coolant connection removed and after changing the Be installed again. This resulted in considerable retooling times when converting the hardening device.
Zur Lösung der gestellten Aufgabe wird nun erfindungsgemäß vorgeschlagen, eine Vorrichtung zum aufeinanderfolgenden Härten der Lagerflächen von unterschiedlich dimensionierten Kurbelwellen von Brennkraftmaschinen mit Hilfe von zwei oder mehreren in vertikalen Ebenen beweglichen Induktoren, die in Achsrichtung der Kurbelwelle verschieblich sind, dadurch zu verbessern, daß mindestens zwei Induktorensätze (I, II, III), bestehend jeweils aus einem bestimmten Kurbelwellentyp angepaßten Induktoren mit zugehörigen Transformatoren, elektrischen Anschlußleitungen, Elektrokühl- und Abschreckflüssigkeits-Förderleitungen und Heb- und Senkmechanismus, die in Achsrichtung der zu härtenden Kurbelwelle aus der Wartestellung in die Arbeitsstellung verschiebbar angeordnet sind. Dabei ist jeweils der in die Arbeitsstellung geschobene Induktorsatz (II) an die Stromversorgung selbsttätig ankuppelbar.To solve the task now proposed according to the invention, a device for successive hardening of the bearing surfaces of different sized crankshafts from Internal combustion engines using two or more in vertical planes moving inductors, which in Axial direction of the crankshaft are displaceable to improve that at least two sets of inductors (I, II, III), each consisting of a specific one Crankshaft type adapted inductors with associated Transformers, electrical connecting cables, Electric cooling and quench liquid delivery lines and lifting and lowering mechanism in the axial direction of the hardening crankshaft from the waiting position into the Working position are slidably arranged.

Über eine Steckverbindung 10 ist das Induktorgehänge an die Stromversorgung 12 ankuppelbar.According to FIG. 1, each inductor set I, II, III consists of two or more inductor hangers. In the case of Fig. 1, there are three each. The structure of a Induktorgehänges comprises according to FIG. 2 the inductor 1 itself, the associated transformer 2, the electrical connecting line 3, the feed line 4 for the Elektrokühl- and quenching the heated from an integrated in the inductor quench nozzles on after completion of the inductive heating Workpiece surface is sprayed for hardening the same, and the lifting and lowering mechanism 5 . The inductor suspension can be coupled to the power supply 12 via a plug connection 10 .
Die Erfindung besteht nun darin, von den vorhandenen Induktorsätzen I, II, III jeweils denjenigen durch Verschieben aller Induktorensätze I bis III in Pfeilrichtung 11 parallel zur Achse der zu härtenden Kurbelwelle 6 zu verschieben, bis der den jeweils zu härtenden Kurbelwellentyp angepaßte Induktorsatz in Arbeitsstellung über der Kurbelwelle 6 steht. Bei der Ausführung gemäß Fig. 1 ist es der Induktorsatz II, der an die Stromversorgung angeschlossen ist, während die benachbarten in die Wartestellung verschobenen Induktorensätze I und III vom Stromnetz abgekuppelt sind. The invention now consists of moving the existing inductor sets I, II, III to those by moving all the inductor sets I to III in the direction of arrow 11 parallel to the axis of the crankshaft 6 to be hardened until the inductor set adapted to the hardened crankshaft type is in the working position the crankshaft 6 stands. In the embodiment of Fig. 1 it is the Induktorsatz II, which is connected to the power supply, while the adjacent shifted to the waiting position Induktorensätze I and III disconnected from the mains.

Nach Lösen des jeweils in Arbeitsstellung befindlichen Induktorensatzes II und der Stromversorgung werden die Induktorensätze I, II, III soweit verschoben, bis der auf den neuen zu härtenden Kurbelwellentyp angepaßte Induktorsatz in die Arbeitsstellung gelangt ist. Das Anschließen dieses anderen Induktorensatzes an das Stromnetz läßt sich problemlos und schnell ohne manuelle Betätigung durchführen. Der Wechsel des Induktorsatzes kann praktisch im Fördertakt der zu härtenden Kurbelwellen durchgeführt werden.After loosening the one in the working position Inductor set II and the power supply are the Inductor sets I, II, III moved until the on adapted to the new crankshaft type to be hardened Inductor set has reached the working position. The Connect this other set of inductors to the Power grid can be easily and quickly without manual Carry out operation. The change of the inductor set can practically in the conveying cycle of the to be hardened Crankshafts are carried out.
Der apparative Mehraufwand für die erfindungsgemäße Vorrichtung wird überwogen durch den Wegfall der beim Umrüsten entstehenden Totzeiten und manueller Betätigung zum Umrüsten.The additional equipment for the inventive Device is predominated by the elimination of the Retrofit resulting dead times and manual operation to convert.
