Abstract

UN PERFORADOR DE PAPEL COMPRENDE UNA PARTE DE BASE (10) Y UNA PALANCA DE PRESION (18) PIVOTALMENTE MONTADA EN COJINETES DE DESCANSO EN LA PARTE DE BASE (10) QUE ACTUAN CONTRA LA FUERZA DE REPOSICION DE UN RESORTE (28), EN UNA PERFORACION DE AGUJERO GUIADA DESLIZANTEMENTE EN LA PARTE DE BASE (10). LA PALANCA DE PRESION (18) TIENE DOS LOBULOS DE COJINETE CURVADOS HACIA ABAJO (28) QUE ESTAN SOBREPUESTOS EN EXTERIOR DE DOS COJINETES DE DESCANSO (14), Y UN FALDON (30) EN LA CARA FRONTAL DE LA PALANCA DE PRESION (18) QUE SE CURVA HACIA ABAJO EN LA ZONA ENTRE LOS COJINETES DE DESCANSO. BAJO LA ACCION DE LA FUERZA DE REPOSICION DEL MUELLE (20), EL FALDON (30) GOLPEA LOS BORDES DE IMPACTO EN LOS COJINETES DE DESCANSO (14) . PARA IMPEDIR QUE SE PILLEN PARTES DE LA MANO, LOS BORDES DE IMPACTO ESTAN MONTADOS EN UNAS EXTENSIONES DE PAREDES FINAS (40) DE LOS COJINETES DE DESCANSO (14) PARALELOS A LOS LOBULOS DE COJINETE (28), MIENTRAS QUE LOS BORDES LATERALES DEL FALDON (30) TIENEN UN DOBLE (34) CERCA DESUS BORDES INFERIORES, QUE JUNTO CON EL LOBULO DE COJINETE ADYACENTE (28), DELIMITA UN HUECO ESTRECHO (38) CUYOS BORDES SE ABREN HACIA LA PARTE DE BASE Y EN EL QUE SE ENGANCHA LA EXTENSION (40).A PAPER PUNCHER INCLUDES A BASE PART (10) AND A PRESSURE LEVER (18) PIVOTALLY MOUNTED ON REST BEARINGS IN THE BASE PART (10) ACTING AGAINST THE RESET FORCE OF A SPRING (28), IN A SLIDING GUIDED HOLE DRILLING IN THE BASE PART (10). THE PRESSURE LEVER (18) HAS TWO DOWN CURVED BEARING LOBES (28) WHICH ARE OVERLAPPED ON THE OUTSIDE OF TWO REST BEARINGS (14), AND A SKIRT (30) ON THE FRONT FACE OF THE PRESSURE LEVER (18) WHICH CURVES DOWN IN THE AREA BETWEEN THE REST BEARINGS. UNDER THE ACTION OF THE SPRING REPOSITIONING FORCE (20), THE SKIRT (30) HITS THE IMPACT EDGES ON THE REST BEARINGS (14). TO PREVENT COLLECTION OF THE HAND, THE IMPACT EDGES ARE MOUNTED ON FINE WALL EXTENSIONS (40) FROM THE REST BEARINGS (14) PARALLEL TO THE BEARING LOBES (28), WHILE THE SIDE EDGES OF THE SKIRT (30) THEY HAVE A DOUBLE (34) CLOSE TO THEIR LOWER EDGES, WHICH, TOGETHER WITH THE ADJACENT BEARING LOBE (28), DELIMINATES A NARROW HOLE (38) WHOSE EDGES OPEN TOWARDS THE BASE PART AND IN WHICH THE EXTENSION HITCHES. (40).
