Embodiment Construction

[0029] The nut 1 selected as the exemplary embodiment consists essentially of a hollow cylindrical nut body 11 with an internal thread 12 . The outer contour of the nut 1 corresponds to conventional contours known in the prior art for a properly positioned insertion. A fastening contour 13 formed by an embedding adjoins the internal thread 12 . The fastening contour 13 comprises a conically enlarged centering section 14 , to which a cylindrically configured outlet section 15 adjoins, which transitions into a likewise cylindrically configured extrusion section 16 with enlarged diameter. middle. A radially outwardly inclined shoulder 17 is formed between the discharge section 15 and the pressing section 16 , so that a conical inwardly tapering ring profile is formed. In the exemplary embodiment, the outlet section 15 is provided with reinforcements (not shown). Furthermore, in the exemplary embodiment, the nut body 11 is provided with a non-illustrated stop toothing on its ab...

Abstract

The invention relates to a nut for fixing to a metal sheet, the nut comprising a nut body which is provided with an internal screw thread. A fixing contour (13) for receiving sheet metal material is situated above the internal screw thread (12), the contour having an enlarged diameter in relation to the core diameter of the internal screw thread (12). The invention also relates to a tool and to a method for connecting a nut (1) of this type to a metal sheet (8).

Description

technical field [0001] The invention relates to a nut for fastening to a sheet metal according to the preamble of patent claim 1 . The invention also relates to a tool for combining such a nut with a sheet metal according to patent claim 9, a nut-sheet compound with such a nut according to patent claim 13 and a tool according to patent claim 13. The method for fastening such a nut to a plate is described in patent claim 14 . Background technique [0002] Various solutions are known for bonding nuts to sheet metal. For example, blanking nuts are used, as are known inter alia from DE 36 26 466 . Such blanking nuts are pressed into the sheet metal without pre-perforations and are used here as punching dies, which punch out the burrs from the sheet metal. The counterforce is here exerted by a counter which supports the sheet metal on the side opposite the blanking nut around the circumference of the burr to be punched out. Punched nuts, in which only the sheet metal is defor...
