Abstract

LA MACHINE COMPREND UN FOUR A LIT FLUIDISE 18 ET UN ORGANE DE PREHENSION 8 QUI PEUT ETRE DEPLACE PAR LES CHARIOTS 4 ET 7 DE FACON A OCCUPER SUCCESSIVEMENT UNE POSITION A LA VERTICALE DE LA TABLE DE CHARGEMENT 11 DES PIECES 10; UNE POSITION BASSE A LA VERTICALE DU FOUR 18, L'ORGANE DE PREHENSION 8 ETANT ALORS SOUMIS A DES VIBRATIONS VERTICALES; ET UNE POSITION A LA VERTICALE DE MORS DE SERRAGE 24 ET 25 TRAVERSES PAR DES CONDUITS 30 D'ALIMENTATION EN AIR DE REFROIDISSEMENT. ON REALISE AINSI SUR UNE SEULE MACHINE LES OPERATIONS DE CHAUFFAGE, COMPRESSION ET REFROIDISSEMENT DE RESSORTS HELICOIDAUX.THE MACHINE INCLUDES A FLUIDIZED BED OVEN 18 AND A GRIP 8 WHICH CAN BE MOVED BY TROLLEYS 4 AND 7 SO AS TO SUCCESSIVELY OCCUPY A VERTICAL POSITION OF THE LOADING TABLE 11 OF THE PARTS 10; A LOW VERTICAL POSITION OF THE OVEN 18, THE GRIPPER 8 THEN BEING SUBJECT TO VERTICAL VIBRATIONS; AND A VERTICAL POSITION OF TIGHTENING JAWS 24 AND 25 THROUGH THE COOLING AIR SUPPLY DUCTS 30. THE HEATING, COMPRESSION AND COOLING OF HELICOIDAL SPRINGS ARE THUS CARRIED OUT ON A SINGLE MACHINE.
