    DESCRIPTION
    Protection cover with refrigeration for cutting discs.
    Object of the invention.
    The object of the invention is a protective cap with cooling for cutting discs; attachable to the housing of a cutter and comprising a semi-cylindrical general cavity that superiorly covers a portion of the cutting disc, and which is delimited by two side walls provided with facing extensions that form a curved perimeter wall.
    This cover has features designed to allow the placement in different positions of a tube with a nozzle for dispensing coolant on the disk and for redirecting to the water cutting disc projected by said disk during its turning movement.
    Field of application of the invention.
    This invention is applicable in disc cutters, and especially, but not limited to, construction material cutters.
    State of the art.
    Currently, disc cutters comprising a cutting disk driven by a motor, and provided with a protective cover or cover defining a cavity of semi-cylindrical general configuration intended to cover a part of the periphery of the disk for security reasons are widely known ; exposing a part of the disc in a cutting area.
    Also known is the incorporation in this type of cutters of a cooling means of the disk, consisting of a supply tube of a cooling liquid, generally water, which pours said cooling liquid over an area of the lateral surface of the disk near its periphery .

    In the known history of cutters this tube is maintained in a fixed position with respect to the disk, the cooling of the disk varying significantly depending on the flow of available liquid, said refrigeration may become insufficient.
    Another of the disadvantages of these cooling means is that the cooling liquid that contacts the disc is quickly projected against a curved perimeter wall of the lid, due to the centrifugal force caused during the rotation of the cutting disc; leaving the cooling liquid from the inside cavity of the lid without practically touching the disk and consequently with a significant waste of the cooling capacity of the liquid used.
    Description of the invention
    The protection cap with cooling for cutting discs; comprising a semi-cylindrical general cavity that superiorly covers a portion of the cutting disc, and which is delimited by two side walls and a curved perimeter wall; it presents constructive particularities oriented to satisfactorily solve the exposed problem, and more specifically to allow the provision of the tube and the dispensing nozzle of coolant in different positions with respect to the cutting disc; and to allow a reuse, in the cooling of the disk, of the projected liquid during the disk rotation, before it leaves the cavity of the lid.
    To achieve these objectives, the cavity of the lid internally comprises, at its periphery, a means for holding a tube and a nozzle for supplying the disk cooling liquid in at least one upper position in which the nozzle pours the liquid onto the upper end of the disc, and a lower position in which the nozzle frontally projects the liquid against the contour of the disc.
    In the studies carried out, it has been found that the disc cools better in situations of low flow if water is thrown from above and for situations of high flow if water is thrown horizontally, therefore the characteristic mentioned allows optimizing the cooling of the disk varying the position of the nozzle, depending on the flow of the available liquid, between: a

    upper position from which the liquid is poured over the upper area of the disc when a small flow rate of liquid is available, and a lower position when a higher flow rate of cooling liquid is available.
    Another relevant feature of the invention is that the side walls of the lid internally comprise recovery fins, and redirection towards the lateral faces of the disk, of the liquid projected by the cutting disk during its turning movement. These fins allow the liquid projected by the disk against the perimeter wall of the lid to be reused to cool the disk before said liquid leaves the lid cavity; optimizing the use of said liquid.
    The aforementioned features and other features of the invention set forth in the appended claims will be more easily understood in view of the exemplary embodiment shown by way of illustration and not limitation in the attached figures, which are described below.
    Description of the figures.
    - Figure 1 shows a front elevation view of the protection cap with cooling for cutting discs
    - Figure 2 shows a front elevation view of the protection cap with cooling for cutting discs
    - Figure 3 shows a front elevation view of the protection cap, in which one of the side walls has been removed to allow observation of the tube and the coolant supply nozzle, said nozzle having been represented with a full stroke in the upper position and dashed in a lower position.
    - Figure 4 shows a perspective view of one of the side walls of the lid seen from its inner face.

    - Figure 5 shows a profile view of an upper portion of the lid and disk sectioned by a vertical plane.
    Preferred embodiment of the invention.
    In Figures 1 and 2, the protection cover (1) with refrigeration for cutting discs is observed; comprising two side walls (11, 12) provided with facing extensions that form a curved perimeter wall (13).
    Said cover (1) superiorly covers a portion of the cutting disc (2).
    The side walls (11, 12) are interconnected by means of an axis (E) of rotation that allows the opening of the cover (1), and are fixed in a closed position by means of a threaded element (14).
    In the closed position, the cover (1) defines an internal cavity (15) which internally comprises, on its periphery, means for holding a tube (3) and a nozzle (31) for supplying the disk cooling liquid (2) in various positions (P1, P2, P3, P4, P5), indicated in Figure 3, between: - an upper position (P1) in which the nozzle pours the liquid vertically over the upper end of the disc ( 2), and - a lower position (P5) in which the nozzle (31) projects frontally, in this case horizontally, the liquid against the contour of the disc (2).
    The intermediate positions (P2, P3 and P4) are evenly distributed between the upper and lower extreme positions (P1, P5).
    The means for securing the tube (3) comprise guides (16) parallel to the curved perimeter wall (13) and which together with said perimeter wall (13) define a passage for the tube housing (3).
    The fastening means of the nozzle (3) comprise appendages (17) and complementary coupling housings (32) defined inside the cover (1) and in the nozzle (31).
    As can be seen in Figures 4 and 5, the side walls (11, 12) of the cover internally comprise fins (18) for recovery, and for redirection towards the lateral faces of the disk (2), of the liquid projected towards the wall perimeter (13) by the cutting disc itself (2), during its turning movement, due to the centrifugal force.
    Once the nature of the invention has been sufficiently described, as well as an example of a preferred embodiment, it is stated to the appropriate effects that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not imply alteration of the essential features of the invention that are claimed below.
