Abstract

Dispositivo di bloccaggio e di sostituzione per lame di seghe circolari, costituito da un albero ruotante (2) sul quale é fissata una lama di sega circolare (3) mediante due flange contrapposte (4, 32) e un dado (5).L'albero (2) presenta, ad un'estremità, una sporgenza (10) ovvero un incavo per l'applicazione di un attrezzo di fissaggio o di sbloccaggio della lama.L'attrezzo di fissaggio é costituito da un perno (12), disposto allo stesso asse dell'albero (2), l'estremità del quale si accoppia con la sporgenza (10).La sostituzione della lama (3) é ottenuta mediante lo sbloccaggio del dado (5) ad opera dell'attrezzo di fissaggio il quale preleva sia il dado (5) che la flangia (4) allontanandoli dalla sopracitata lama di sega (3).Locking and replacement device for circular saw blades, consisting of a rotating shaft (2) on which a circular saw blade (3) is fixed by means of two opposing flanges (4, 32) and a nut (5). at one end, the shaft (2) has a protrusion (10) or a recess for the application of a blade fixing or unlocking tool. The fixing tool consists of a pin (12), arranged at the same shaft axis (2), the end of which is coupled with the protrusion (10). The replacement of the blade (3) is obtained by releasing the nut (5) by means of the fixing tool which picks up both the nut (5) and the flange (4) moving them away from the aforementioned saw blade (3).
