Abstract

EN LA PLEGADORA DE CHAPA ESTAN PRESENTES FILAS DE CUÑOS, TROQUELES Y UNIDADES MODULARES QUE CONSTITUYEN EXTENSIONES DE CUÑOS Y MORDAZAS DE SUJECION PARA DICHOS CUÑOS Y EXTENSIONES. EL SISTEMA DE AIRE COMPRIMIDO SE CARACTERIZA EN QUE: -LA SUJECION DE LAS MORDAZAS TIENE LUGAR A TRAVES DE TORNILLOS PUESTOS EN TENSION POR MEDIO DE DISPOSITIVOS DE ACCIONAMIENTO DE CILINDRO DE AIRE COMPRIMIDO; -LA ALIMENTACION DE LOS CILINDROS DE AIRE COMPRIMIDO DE LOS DISPOSITIVOS DE ACCIONAMIENTO TIENE LUGAR A TRAVES DE CONDUCTOS HECHOS DENTRO DEL CUERPO DE LAS MORDAZAS Y/O DE DICHAS EXTENSIONES Y A TRAVES DE TUBOS QUE CORREN ENTRE LAS MORDAZAS Y/O DICHAS EXTENSIONES DE CADA PAR ADYACENTE; Y -LOS TUBOS QUE CORREN ENTRE DICHAS EXTENSIONES SON TUBOS DE METAL CON UN EJE HORIZONTAL RECTO QUE CORRE PARCIALMENTE ENTRE LAS EXTENSIONES DE CADA PAR ADYACENTE Y ESTAN PARCIALMENTE INSERTADOS EN CAVIDADES HECHAS EN LOS LADOS DE DICHAS EXTENSIONES CON LA CAPACIDAD DE CORRER DE FORMA ESTANCA DENTRO DE DICHAS CAVIDADES.ROWS OF WEDGES, DIES AND MODULAR UNITS ARE PRESENT IN THE PLATE BENDING MACHINE, WHICH CONSTITUTE WEDGE EXTENSIONS AND CLAMPING JAWS FOR SUCH WEDGES AND EXTENSIONS. THE COMPRESSED AIR SYSTEM IS CHARACTERIZED IN THAT: -THE CLAMP OF THE CLAMPS HAS PLACE THROUGH TENSIONED SCREWS THROUGH COMPRESSED AIR CYLINDER DRIVING DEVICES; -THE SUPPLY OF THE COMPRESSED AIR CYLINDERS OF THE DRIVING DEVICES HAS PLACE THROUGH DUCTS MADE WITHIN THE BODY OF THE CLAMPS AND / OR OF SUCH EXTENSIONS AND THROUGH TUBES THAT RUN BETWEEN THE CLAMPS AND / OR SOME OF THESE ADJACENT; AND -THE TUBES THAT RUN BETWEEN THESE EXTENSIONS ARE METAL TUBES WITH A STRAIGHT HORIZONTAL AXLE THAT RUNS PARTIALLY BETWEEN THE EXTENSIONS OF EACH ADJACENT COUPLE AND ARE PARTIALLY INSERTED INTO THE SIDES OF THESE EXTENSIONS WITH THE RIDING CAPACITY OF THESE CAVITIES.
