Title (DE) VORRICHTUNG UND VERFAHREN ZUM HÄRTEN METALLISCHER WERKSTÜCKE
(EN) DEVICE AND METHOD FOR HARDENING METAL WORKPIECES
(FR) DISPOSITIF ET PROCÉDÉ DE DURCISSEMENT DE PIÈCES MÉTALLIQUES
Abstract:
(DE) Die vorliegende Erfindung betrifft eine Vorrichtung und ein entsprechendes Verfahren zum partiellen Härten eines metallischen Werkstücks, wobei das Werkstück (20) mittels einer Fördereinrichtung (11) in einem Durchlauf ofen entlang einer Förderrichtung (28) transportiert und mittels einer Heizeinrichtung (12, 14, 16) partiell erwärmt wird. Dabei ist vorgesehen, dass die Heizeinrichtung (12, 14, 16) zumindest eine Heizzone (30) erzeugt, die mit dem Werkstück (20) in Förderrichtung (28) bewegt wird.
(EN) The present invention relates to a device and to a corresponding method for partially hardening a metal workpiece, wherein the workpiece (20) is transported by means of a conveyor device (11) in a continuous furnace along a conveying direction (28), and is partially heated by means of a heating appliance (12, 14, 16). According to the invention, the heating appliance (12, 14, 16) generates at least one heating zone (30) moving in the conveyor direction (28) with the workpiece (20).
(FR) La présente invention concerne un dispositif et un procédé correspondant de durcissement partiel d'une pièce métallique, la pièce (20) étant transportée au moyen d'un dispositif de transport (11) dans une direction de transport (28) qui traverse un four et étant partiellement chauffée au moyen d'un dispositif de chauffage (12, 14, 16). Selon l'invention, le dispositif de chauffage (12, 14, 16) forme au moins une zone de chauffage (30) qui est déplacée avec la pièce (20) dans la direction de transport (28).
