Patent ID: 8381564

Claim:
A method for the production of a cage nut consisting of a cylindrical nut body having a coaxial bore provided with an interior thread which is ending in a rectangular plate and which by means of the rectangular plate floatingly is supported within a cage, wherein the entire cage nut, nut body, and cage, by means of the method steps tube-forming, thread-cutting, bending, and punching is produced from a single strip of metal sheet and, herein in the strip of metal sheet, which is having the shape of a long tape, a tube is drawn and in a distance there-from in a longitudinal direction a circular punch-out is produced and, wherein the distance between the tube and the punch-out in the strip of metal sheet is chosen corresponding to the sum of height and length of the cage and, wherein the strip of metal sheet is punched or cut into sections, which each are having a length of about two times the height plus three times the length of the cage, wherein the punch-out is positioned in the centre of the section and, the punch-out is first bent around a first axis at a first location perpendicularly upward such that a part of the section, which is comprising the tube, as well as a further part of the section perpendicularly are extending upwardly, characterized in that the part of the section, which is comprising the tube again is bent around a second axis which is parallel and distant from the first axis, such that the tube concentrically projects toward the punch-out, and after the final bending the caged nut is from a single sheet, that is consisting of an upwardly bent part and a perpendicularly further part.
