Abstract

DISPOSITIF DE SOUDAGE DESTINE A LA FABRICATION DE MATS CONIQUES OU ANALOGUES A PARTIR DE TUBES FENDUS, QUI PERMET AU TUBE FENDU A SOUDER DE PASSER PAR LE DISPOSITIF DE SOUDAGE FIXE EQUIPE D'UN MECANISME DE SERRAGE ET D'UN GUIDE, EN ETANT D'UNE PART AJUSTE PAR CE DERNIER ET D'AUTRE PART COMPRIME ET SERRE PAR L'INTERMEDIAIRE DE GALETS PRESSEURS. LE GUIDE COMPORTANT UN SUPPORT DE SOUDURE 49 EST RELIE RIGIDEMENT AU CADRE 25 DU DISPOSITIF DE SOUDAGE QUI COMPORTE PLUSIEURS GALETS PRESSEURS 21, 22 AGISSANT RADIALEMENT SUR LA PAROI DU TUBE FENDU 9 ET FAISANT PARTIE D'ORGANES DE POUSSEE 26, 28 REPARTIS SUR LA PERIPHERIE DU TUBE, L'ORGANE DE POUSSEE 26 MUNI D'UN GALET PRESSEUR 21 ETANT FIXE AU CADRE 25 ET LES AUTRES ORGANES DE POUSSEE MUNIS DES GALETS PRESSEURS 22 POUVANT COULISSER RADIALEMENT.WELDING DEVICE INTENDED FOR THE MANUFACTURING OF CONICAL OR SIMILAR MATS FROM SLOTTED TUBES, WHICH ALLOWS THE SLOTTED TUBE TO BE WELDED TO PASS THROUGH THE FIXED WELDING DEVICE EQUIPPED WITH A TIGHTENING MECHANISM AND A GUIDE, AS A ONE PART ADJUSTED BY THE LATTER AND ON THE OTHER PART COMPRESSED AND TIGHTENED BY THE INTERMEDIATE OF PRESSURE ROLLERS. THE GUIDE CONTAINING A WELDING SUPPORT 49 IS RIGIDLY CONNECTED TO THE FRAME 25 OF THE WELDING DEVICE WHICH INCLUDES SEVERAL PRESSURE ROLLERS 21, 22 ACTING RADIALLY ON THE WALL OF THE SLOTTED TUBE 9 AND FORMING PART OF PUSHING UNITS 26, 28 DISTRIBUTED ON THE PERIPHERY OF THE TUBE, THE PUSHING UNIT 26 EQUIPPED WITH A PINCH ROLLER 21 BEING FIXED TO THE FRAME 25 AND THE OTHER PUSHING UNITS EQUIPPED WITH PRESSURE ROLLERS 22 THAT CAN SLIDE RADIALLY.
