Described is a method for making cases for firearms of the type comprising a substantially cylindrical rigid pipe (2), a plastically deformable reinforcing element (6) pre-shaped with a substantially cylindrical side wall (12) and with a bottom wall (13) along whose perimeter edge (14) the side wall (12) of the reinforcing element (6) is flared outwards in such a way as to form a side anchoring tooth (15), and a substantially cylindrical rigid base (7), which has a tubular side wall (8) and a bottom wall (9) along whose perimeter edge (10) the side wall (8) is flared outwards in such a way as to form a collar (11) which has internally a seat undercut; the method comprises inserting the reinforcing element (6) in the pipe (2), and both in the base (7) until they make contact with the bottom wall (9) of the base(7); and axially compressing the reinforcing element (6) in such a way that, by deforming plastically, it expands radially until securing the pipe (2) against the inner side wall (8) of the base (7), and until inserting the anchoring tooth (15) inside the collar (11) with the consequent radial deformation of an end edge (5) of the pipe (2), which is thus secured, in flared configuration, between the anchoring tooth (15) and the collar (11). |
