Abstract

EL PRESENTE INVENTO SE REFIERE A UN ESTIRADOR DE CHAPAS QUE CONSTA DE: A) UNA ESTRUCTURA DE SOPORTE FORMADA POR UN PORTAPUNZON Y POR UNA PIEZA OPUESTA, CONECTADA POR AL MENOS DOS, Y PREFERENTEMENTE CUATRO, ELEMENTOS TENSORES; B) UN PUNZON SUJETO POR LA PRIMERA PIEZA QUE SE ACOPLA Y DESACOPLA CON UN TROQUEL CORRESPONDIENTE, DETERMINANDO DICHO ACOPLAMIENTO LA FORMA DEL ESTIRADO; C) UN CUERPO DE TOPE QUE SOSTIENE DICHO TROQUEL Y QUE SE DESLIZA A LO LARGO DE LOS TENSORES SEGUN UN RECORRIDO QUE SE CORRESPONDE, AL MENOS, CON LA PROFUNDIDAD DEL ESTIRADO A OBTENER. ESTE CUERPO ESTA FORMADO POR UN PRIMER ELEMENTO QUE SUJETA DICHO TROQUEL Y POR UN SEGUNDO ELEMENTO. AMBOS VA ACOPLADOS MEDIANTE PISTONES DE CORTO RECORRIDO SUJETOS POR UNO DE DICHOS ELEMENTOS. EL SEGUNDO ELEMENTO PUEDE BLOQUEARSE EN POSICION DE TRABAJO MEDIANTE UN CIERRE MECANICO. LA PRESION DE TRABAJO NECESARIA PARA EL ESTIRADO SE OBTIENE MEDIANTE LA ACCION DE DICHOS PISTONES DE CORTO RECORRIDO. EL DESLIZAMIENTO DEL CUERPO DE TOPE NECESARIO PARA LA EXTRACCION DE LA PARTE ESTIRADA SE OBTIENE MEDIANTE LA LIBERACION DEL CIERRE MECANICO.THE PRESENT INVENTION REFERS TO A SHEET STRETCHER CONSISTING OF: A) A SUPPORT STRUCTURE FORMED BY A PUNCH HOLDER AND AN OPPOSING PART, CONNECTED BY AT LEAST TWO, AND PREFERABLY FOUR, TENSIONING ELEMENTS; B) A PUNCH HOLDED BY THE FIRST PIECE THAT COUPLES AND UNCOUPLES WITH A CORRESPONDING DIE, DETERMINING SUCH COUPLING THE FORM OF THE STRETCH; C) A BODY OF STOP THAT SUPPORTS SUCH DIE AND THAT SLIDES ALONG THE TENSIONERS ACCORDING TO A JOURNEY THAT CORRESPONDS, AT LEAST, WITH THE DEPTH OF THE STRETCH TO BE OBTAINED. THIS BODY IS FORMED BY A FIRST ELEMENT THAT HOLDS SUCH A DIE AND BY A SECOND ELEMENT. BOTH IS COUPLED THROUGH SHORT TRAVEL PISTONS SUBJECTED BY ONE OF THESE ELEMENTS. THE SECOND ELEMENT CAN BE LOCKED IN WORKING POSITION THROUGH A MECHANICAL LOCK. THE NECESSARY WORKING PRESSURE FOR THE STRETCH IS OBTAINED THROUGH THE ACTION OF THESE SHORT TRAVEL PISTONS. THE SLIDING OF THE BODY NECESSARY FOR THE EXTRACTION OF THE STRETCHED PART IS OBTAINED THROUGH THE RELEASE OF THE MECHANICAL SEAL.
