Abstract

Perfeccionamiento en las cajas de soporte y de guía de un mandril en los laminadores continuos de mandril retenido, durante sus desplazamientos a lo largo del eje de laminación, caracterizados por comprender: - una estructura portante (5) de caja, que posee un eje horizontal (A) destinado a coincidir con el eje (L) de laminación del citado laminador (1); - tres palancas (9, 10, 11) apoyadas sobre correspondientes pernos horizontales (6, 7, 8), soportados por la citada estructura portante (5) y extendidos paralelamente al citado eje (A) de la estructura, presentando los citados pernos, en un plano vertical, correspondientes asientos dispuestos en los vértices de un triángulo equilátero, el baricentro del cual es el asiento del citado eje horizontal (A) de la estructura portante (5); - tres rodillos (12, 13, 14) cada uno de los cuales está montado loco en un extremo (9a, 10a, 11a) de una correspondiente palanca (9, 10, 11) y presentando un eje de rotación que cruza el eje del perno de apoyo de la citada palanca, encontrándose los ejes de rotación de los citados rodillos (12, 13, 14) en un plano común perpendicular al citado eje (A) de la estructura portante (5); - elementos motores (16, 17) para desplazar angularmente y simultáneamente los citados rodillos (12, 13, 14) alrededor de los citados pernos (6, 7, 8), hacia y desde el citado eje (A) de la estructura portante (5), con desplazamientos iguales y del mismo sentido.
