CA 2572655

The invention relates to a method for stabilizing the two snap temperatures of snap elements made of thermostatic bimetal. According to said method, the mechanical steps are not interrupted by the required thermal treatment such that the embossed snap elements are pressed flat several times at a great aging temperature. The snap elements remain in the automatic production device during said process and can then be further processed in the automatic device.

L'invention concerne un procédé pour stabiliser les deux températures momentanées d'éléments à cliquet à bilame thermique, procédé pendant lequel les opérations exécutées par des machines ne sont pas interrompues par le traitement thermique nécessaire. Selon l'invention, les éléments à cliquet matricés sont plusieurs fois emboutis sur un plan à une température de vieillissement élevée. Selon ce procédé, les éléments à cliquet restent dans l'installation automatique de production, dans laquelle ils sont ensuite usinés.
