Title
(EN) ENERGIZATION CYCLE COUNTER FOR INDUCTION HEATING TOOL
(FR) COMPTEUR DE CYCLES D'EXCITATION POUR OUTIL DE CHAUFFAGE PAR INDUCTION
Abstract
(EN)
An induction heat treating process with a remote sensor for monitoring the duration of energization of an induction heating coil each time the induction heating coil is consecutively cycled. An identifying tag is preferably attached to, embedded within the induction heating, coil or within, the surrounding area of the induction coil and transmits a signal to a remote counting sensor that .is preferably triggered by and responds to the change in voltage generated as the coil is energized. Alternative means of measuring a cycle may be implemented. The output data from the sensor provides useful information for determining the lifespan of an induction heating coil. Predicting the lifespan of a coil optimizes production by anticipating failure and. replacement of a coil during a predetermined down time, limiting on-site inventory, and revolutionizing, the billing cycle based on a per cycle cost while decreasing overall production costs and improving inductor coil quality.
(FR)
L'invention concerne un processus de traitement thermique par induction comprenant un capteur distant qui contrôle la durée d'excitation des bobines de chauffage par induction à chaque nouveau cycle consécutif de la bobine de chauffage. Une étiquette d'identification est de préférence fixée sur la bobine de chauffage par induction ou incorporée dans cette dernière, ou dans la zone entourant la bobine, et transmet un signal à un détecteur-compteur distant, lequel est de préférence activé par la modification de tension se produisant lorsque la bobine est excitée, et réagit à cette modification de tension. D'autres moyens de mesure du cycle peuvent en outre être utilisés. Les données de sortie du capteur fournissent des informations utiles permettant de déterminer la durée de vie d'une bobine de chauffage par induction. Cette prédiction de la durée de vie d'une bobine permet d'optimiser la production en anticipant les défaillances et le remplacement d'une bobine pendant un temps d'indisponibilité prédéterminé, en limitant les inventaires sur place, et en révolutionnant le cycle de facturation par l'introduction d'un coût par cycle, tout en diminuant les coût de production globaux et en améliorant la qualité des bobines d'induction.
