  • the basis of the invention is the task to provide an independent change in the parameters of the thermal program in accordance with the weight of the burning parts, which, in turn, will significantly reduce the risks of low-quality firing.
  • the registration device comprises a weight sensor with an actuator for linear movement, at least one end microswitch for fixing the lower position or two extreme positions of the weight sensor and a movable stand, mounted on a weight sensor, and the outputs of the weight sensor of the actuator and the final microswitch are connected to the control device.
  • the distance of moving the movable stand from the lower position to the upper position in the weighing mode is at least 0.3 mm, and the distance of moving the weight sensor from the upper position in the weighing mode to the lower position is at least 0.5 mm longer than the movement of the movable stand resting in the lower position on the bottom cover of the furnace body.
  • the linear actuator provides vertical movement of the weight sensor, the upper position is the weighing mode, the lower is the idle position.
  • the movable stand in the lower position rests on the bottom cover of the furnace body, which provides mechanical protection for the weight sensor from breakage in the lower idle position.
  • the movable stand which in the lower position rests on the bottom cover of the furnace body, protects the weight sensor from overheating and from mechanical damage when it is in the lower idle position.
  • the distance of moving the weight sensor from the upper position (weighing mode) to the lower position is at least 0.5 mm longer from the movement of the movable stand, which protects the weight sensor from mechanical damage when it is in the lower position (inoperative position).

Abstract

Le four de stomatologie comprend un corps (1), une chambre de recuit (2), une table de travail (3), un dispositif de commande (6), un dispositif d'affichage (8) et un dispositif d'enregistrement doté d'un mécanisme effecteur de déplacement linéaire d'un capteur de poids (9), un micro-interrupteur d'extrémité (11) et un support mobile (12) disposé sur le capteur (9). Les sorties du capteur de poids (9), du mécanisme effecteur (10) et du micro-interrupteur d'extrémité (11) sont branchées sur le dispositif de commande (6). Grâce à la pesée directe des pièces pour la reconstruction dentaire, on apporte aux paramètres du programme thermique des modifications plus objectives, ce qui améliore sensiblement la qualité du recuit des pièces de reconstruction dentaires.
