Abstract

LA INVENCION SE REFIERE A UN PROCESO DE EXTRUSION RADIAL COMBINADO CON UNA DE HERRAJE DEL INTERIOR DEL TUBO, QUE ES UNA ESENCIA DE UN PROCESO DE EXTRUSION EN FRIO Y QUE SE PUEDE INCLUIR DENTRO DE LOS PROCESOS DE CONFORMACION DE METALES VOLUMETRICOS. SEGUN EL PROCESO, A PARTIR DE SEMIPRODUCTOS METALICOS EN FORMA DE TUBO SE PUEDAN FORMAR DIFERENTES PIEZAS CONFORMADAS FINALES O PIEZAS EN LAS QUE SE VA A REALIZAR UN TRABAJO ADICIONAL, POR EJEMPLO, UN TRABAJO MECANICO. EL PROCESO CONSISTE EN INTRODUCIR UN TUBO (1), UN EXTREMO DEL CUAL SE PUEDE EXPANDIR PREVIAMENTE, EN UNA MATRIZ CONFORMADA APROPIADA (3), EN DONDE EN UN LATERAL HAY UN PUNZON (4) QUE QUEDA RETENIDO POR UNA FUERZA DETERMINADA (F{SUB,1}) Y DENTRO DEL CUAL HAY UNA MANDRIL QUE SE PUEDE MOVER LIBREMENTE (5), MIENTRAS QUE DESDE EL OTRO LADO RESPECTO A LA CARRERA DE TRABAJO CONTRA-PUNZON (2) EXTRUYE LA DIFERENCIA DE VOLUMEN DEL TUBO RESULTANTE DEL HERRAJE DEL TUBO (1), EN LA DIRECCION DE LA TRAYECTORIA DEL CONTRA-PUNZON (2) DE MODO QUE EL MATERIAL RELLENA EL ESPACIO INICIAL QUE HAY ENTRE EL MANDRIL (5) Y EL TUBO (19; EL ESPACIO ENTRE EL TUBO (1) Y EL PUNZON (2) Y EL ESPACIO CONFORMADO ARBITRARIO (B) DEL PUNZON (2) O DE LA MATRIZ (3).THE INVENTION REFERS TO A RADIAL EXTRUSION PROCESS COMBINED WITH A HARDWARE OF THE INTERIOR OF THE TUBE, WHICH IS AN ESSENCE OF A COLD EXTRUSION PROCESS AND WHICH CAN BE INCLUDED WITHIN THE PROCESSES OF THE CONFORMATION OF VOLUMETRIC METALS. ACCORDING TO THE PROCESS, DIFFERENT FINAL CONFORMED PARTS OR PARTS IN WHICH AN ADDITIONAL WORK WILL BE PERFORMED, FOR EXAMPLE, A MECHANICAL WORK, CAN BE FORMED FROM METAL SEMI-PRODUCTS. THE PROCESS CONSISTS OF INTRODUCING A TUBE (1), AN END OF WHICH CAN BE PREVIOUSLY EXPANDED, IN AN APPROPRIATE CONFORMED MATRIX (3), WHERE ON A SIDE THERE IS A PUNCH (4) THAT IS RETAINED BY A DETERMINED FORCE (F { SUB, 1}) AND WITHIN WHICH THERE IS A CHUCK THAT CAN BE MOVED FREELY (5), WHILE FROM THE OTHER SIDE WITH RESPECT TO THE JOB RACE AGAINST PUNCH (2) IT EXTRACTES THE DIFFERENCE OF VOLUME FROM THE TUBE RESULTING FROM THE TUBE (1), IN THE DIRECTION OF THE PATH OF THE COUNTER-PUNCH (2) SO THAT THE MATERIAL FILLS THE INITIAL SPACE THAT IS BETWEEN THE CHUCK (5) AND THE TUBE (19; THE SPACE BETWEEN THE TUBE (1) AND THE PUNCH (2) AND THE ARBITRARY CONFORMED SPACE (B) OF THE PUNCH (2) OR OF THE MATRIX (3).
