Abstract

SE HA PRESENTADO UNA PRENSA HIDRAULICA O MECANICA CON UNA INSTALACION TREFILADORA O UN ESCALON DE TREFILACION PARA UNA PRENSA ESCALONADA, QUE LLEVA UN PORTAHERRAMIENTA DE EMBUTICION (8) UNIDO EN ARRASTRE DE FUERZA, A TRAVES DE VARIAS VARAS DE TRACCION (12), A UN BASTIDOR SUJETADOR DE CHAPA (13) SITUADO POR DEBAJO DE UNA BANCADA DE PRESION (10). EN EL BASTIDOR SUJETADOR DE CHAPA (13) SE ENCUENTRAN CUATRO UNIDADES DE EMBOLO-CILINDRO (14-16) QUE SIRVEN PARA EL APOYO DE LOS CUATRO PUNTOS ANGULARES DE LA BANCADA DE PRESION (10) Y QUE, DURANTE EL PROCESO DE TREFILACION, SUJETAN HIDRAULICAMENTE EL SOPORTE DE CHAPA (6).A HYDRAULIC OR MECHANICAL PRESS HAS BEEN PRESENTED WITH A WINDING INSTALLATION OR A WINDING STAGE FOR A STAGED PRESS, CARRYING A STAMPING TOOL (8) ATTACHED IN FORCES OF FORCE, THROUGH SEVERAL 12 OF THEM PLATE HOLDER FRAME (13) LOCATED BELOW A PRESSURE BENCH (10). FOUR PITCH-CYLINDER UNITS (14-16) ARE FOUND IN THE PLATE HOLDING FRAME (13) THAT SUPPORT THE FOUR ANGULAR POINTS OF THE PRESSURE ROD (10) AND, DURING THE TREFILATION PROCESS, HYDRAULICALLY THE SHEET SUPPORT (6).
