Abstract

UN PROCEDIMIENTO SUCESIVO PARA LA ELABORACION DE PIEZAS ESTAMPADAS EN VARIOS PASOS, COMO PASO DE FORMA, PASO DE RETENIDA, RECORTE DE ESTAMPA, DONDE EN EL RECORTE DE ESTAMPA LA PIEZA ESTAMPADA SE RECORTA POR UN PUNZON ESTAMPADOR CORRESPONDIENTE AL CONTORNO EXTERIOR DE LA PIEZA ESTAMPADA EN ACCION CONJUNTA CON UN MATRIZ. EL PROBLEMA TECNICO ES LA PREPACION DE UN PROCEDIMIENTO SUCESIVO, SE TRANSPORTA LA PIEZA ESTAMPADA CON UNA ENTRADA DE ESTAMPADO, QUE DESAPARECE. EN EL PASO DE PRENSADO QUE PRECONECTA EL RECORTE DE ESTAMPADO SE EFECTUA UN PRENSADO EN LA PROFUNDIDAD DE UNA PIEZA DE FRACCION DE ESPESOR DE LA BANDA DEL ESTAMPADO CON UN CONTORNO EXTERIOR ALGO MAS GRANDE QUE EL CONTORNO EXTERIOR DE LA PIEZA ESTAMPADA Y EL USO DE ESTAMPADO QUE SE PRODUCE EN EL PASO ESTAMPADOR SE LLEVA EN EL RECORTE DEESTAMPADO PARA EL FENIDO, ASI QUE SE MANTIENE UNA SUPERFICIE DE CORTE CON LINEA PERFILADA EXACTA. UNA HERRAMIENTA SUCESIVA ABARCA UN PUNZON DE ESTAMPADO CON DIFERENCIAS MAS GRANDES TRANSVERSALES QUE LA PIEZA ESTAMPADAA SUCCESSIVE PROCEDURE FOR THE ELABORATION OF STAMPED PIECES IN SEVERAL STEPS, AS A SHAPE STEP, RETAINED STEP, STAMP CUTTING, WHERE IN THE STAMP CUT THE STAMPED PIECE IS CUT BY A CORRESPONDING STAMP PUNCH AT THE BACK JOINT ACTION WITH A MATRIX. THE TECHNICAL PROBLEM IS THE PREPARATION OF A SUCCESSIVE PROCEDURE, THE STAMPED PART IS TRANSPORTED WITH A STAMPED ENTRY, THAT DISAPPEARS. IN THE PRESSING STEP THAT PRE-CONNECTS THE STAMP CUTTING, A PRESSING IS DEPTHED IN THE DEPTH OF A PIECE OF FRACTION OF THICKNESS OF THE STAMP WITH AN EXTERNAL CONTOUR SOMETHING BIGGER THAN THE EXTERNAL CONTOUR OF THE STAMPED PIECE AND THE USE OF STAMPED WHICH IS PRODUCED IN THE STAMP PASS IS CARRIED IN THE CUTTING UNLOCKED FOR THE FENIDO, SO A CUTTING SURFACE WITH ACCURATE PROFILED LINE IS MAINTAINED. A SUCCESSIVE TOOL COVERS A STAMP PUNCH WITH LARGER CROSS-CUTTING DIFFERENCES THAN THE STAMPED PIECE
