Abstract

Sega motorizzata comprendente una base avente un supporto per il pezzo in lavorazione, ed una stazione di taglio sulla quale viene tagliato un pezzo in lavorazione; una unità di taglio comprendente un motore, un albero sul quale può essere montata in modo rimovibile una lama di sega per la rotazione su un asse dell'albero azionato dal motore, ed un elemento di protezione mobile, spostabile tra posizioni circondanti e non circondanti rispetto ad una parte inferiore della lama della sega; una struttura di montaggio che fissa l'unità di taglio sulla base per lo spostamento tra una posizione non di taglio lontana dalla stazione di taglio ed una posizione di taglio che colloca la lama della sega nella stazione di taglio; un'apparecchiatura di azionamento della protezione mobile collegata tra la base e la protezione mobile per spostare progressivamente la protezione mobile verso la posizione non circondante quando la lama della sega taglia attraverso il pezzo in lavorazione nella stazione di taglio. L'apparecchiatura di azionamento comprende un elemento a moto perso che consente all'elemento di protezione spostabile di essere spostato liberamente con azionamento manuale del medesimo verso la posizione non circondante soltanto quando l'unità di taglio si trova nella posizione non di taglio per esporre la lama della sega per la sua rimozione; un'apparecchiatura di blocco che può entrate in contatto automaticamente con l'apparecchiatura di azionamento dell'elemento di protezione mobile quando l'elemento di protezione mobile si trova nella posizione non circondante per impedire lo spostamento dell'unità di taglio dalla posizione non di taglio sin quando l'elemento di protezione mobile non viene riportato nella posizione circondante la lama della sega.
