The invention relates to a gun for spraying liquid at a very high pressure, referred to as a focusing gun, and to a method for manufacturing same, according to which two elongate parts (2) are manufactured to be assembled so as to form the focusing gun. Each of said parts includes an assembly surface (J) comprising a central groove (3) for forming the duct of the focusing gun once the parts have been assembled, and a gluing tank (9) for being filled with an adhesive substance. Further, at least one of said parts (2) has a centering rib (6), projecting relative to the assembly surface thereof, while the other part has, for each centering rib (6), a centering cavity (7), the size of which is suitable for tightly housing said centering rib. |

1. A method for manufacturing a focusing gun (1) for spraying a liquid at a very high pressure, for a machine for spraying liquid at a very high pressure, comprising:
two pieces (2, 2), each piece comprising an assembly face (J), wherein the two pieces (2, 2′) are joined to form the focusing gun (1): wherein each assembly face (J) includes a central groove (3) formed in a planar median region (4, 5) of each said assembly face and adapted to extend between two ends thereof, said central grooves being adapted to form a duct (12) of the focusing gun (1) in the assembled position of the two pieces (2, 2′), wherein in the assembly face (J) of at least one of the two pieces (2, 2′), laterally with respect to the planar median region (4, 5) thereof, at least one bonding reservoir (9) intended to be filled with a quantity of adhesive substance (11) adapted to adhere to a portion of the assembly face (J) of the other piece (2′, 2) lying opposite said reservoir, in the assembled position of the two pieces, wherein each bonding reservoir (9) is filled with adhesive substance (11), and the two pieces (2, 2′) are placed in contact so that they are joined by their assembly faces (J) and connected by means of the adhesive substance (11),said method being characterized in that:
wherein on the assembly face (J) of at least one piece (2, 2′), at least one centering rib (6) is formed, which projects from said assembly face, and, wherein for each centering rib (6) formed on the assembly face (J) of one piece (2, 2′), a central cavity (7) is formed in the assembly face (J) of the other piece (2′, 2), the central cavity having dimensions adapted to tightly receive each said respective centering rib in the assembled position of the two pieces, in which the central grooves (3) form the duct (12) of the focusing gun (1). |
