Cooling device for disc cutters

A cooling device for disc cutters with a protective cover which covers approximately an upper half of a cutter disc, said cooling device comprising:

• a tube configured to supply coolant and a nozzle configured to pour coolant on the cutter disc;
• a curved, tubular guide having a radius of curvature greater than the cutter disc, the curved, tubular guide attached inside the protective cover and concentric with a periphery of the cutter disc;
• a curved cannula made of semi-rigid material, and mounted inside the curved guide capable of longitudinal movement between two end positions and provided with an upper end connected to the tube for supplying coolant and a lower end which protrudes below the protective cover and wherein the nozzle is coupled;
• and
• a fastening device configured to attach the curved cannula at different points of a path thereof, such that during the movement of the curved cannula, the nozzle moves over a lower sector of the periphery of the cutter disc;
• wherein the fastening device comprises a fastening clip attached to the cannula and which protrudes through a groove that passes through at least one section of the curved guide and passes through an outer surface of the protective cover;
• wherein the fastening device enables, during cutting of parts of different thicknesses, the nozzle to be located at different heights and facing a contact and penetration area of a part to be cut.
