Abstract

Procedimiento de fabricación de chapas perforadas, caracterizado porque se toma la hoja de chapa desenrollada de una bobina por aprieto de una primera pinza que forma parte de un sistema de alimentación de paso grande para introducirla en un útil de punzonado, después del centrado automático de la chapa con relación al útil de punzonado, se mantiene la chapa tensada en el útil por aprieto de una segunda y una tercera pinzas que forman parte de un sistema de alimentación de paso pequeño, colocadas a uno y otro lado de la zona a punzonar y acoplarse rígidamente entre sí, se desaprieta la primera pinza y se efectúa el punzonado de los agujeros fila por fila con ayuda del sistema de alimentación de paso pequeño, cons escamoteo automático de los punzones en las zonas de ausencia de agujeros , después de la terminación de los punzonados, se efectúa el aprieto de la primera pinza y luego el desaprieto de la segunda y de la tercera pinzas y se asegura, con ayuda del sistema de alimentación de pasogrande, al transferencia de la chapa punzonada del útil hasta una cizalla, con introducción simultánea de una parte virgen en el útil.
