Abstract

Die Erfindung betrifft ein Verfahren zum Härten jeweils eines einzelnen, ringförmigen Werkstückes sowie eine hierzu ausgebildete Fixtur, bei welchem ein einzelnes, zu härtendes ringförmiges Werkstück mit dessen Öffnung über einen Dorn gestülpt wird, bis das Werkstück mit einer ersten Stirnfläche auf einer Auflage aufliegt; ein oder mehrere Niederhalter von einer der ersten Stirnfläche entgegen gerichteten Seite in Richtung des Auflagers zugeführt wird bzw. werden, bis der bzw. die Niederhalter auf einer der ersten Stirnfläche entgegen gerichteten zweiten Stirnfläche des Werkstücks kraftbeaufschlagt aufliegt bzw. aufliegen; kaltes gasförmiges Abschreckmittel zumindest an das Werkstück begrenzende und zueinander entgegen gerichtete Flächen des Werkstückes zugeführt wird; und erwärmtes Abschreckmittel abgeführt wird.

Figure imgaf001
The invention relates to a method for hardening each of a single, annular workpiece and a fixture designed for this purpose, in which a single, to be hardened annular workpiece with its opening is slipped over a mandrel until the workpiece rests with a first end face on a support; one or more hold-downs is supplied from one of the first end face opposite side in the direction of the support or are, until the or the hold-down on a first end face oppositely directed second end face of the workpiece rests or rest; cold gaseous quenching agent is supplied at least to the workpiece limiting and mutually opposing surfaces of the workpiece; and heated quenching agent is removed.
