The invention relates to a rivet element (10) to be fastened to a component (51), in particular to a fiber composite component. Said rivet element has a flange portion (21), which, when fastened, rests against the component, and a rivet portion (11). The rivet portion comprises a tip (12a), converging away from the flange portion, a flared end portion (12b) being provided at the end of the tip which is remote from the flange portion.

Disclosed are a method and a device for mounting a fastening element (12, 12') on a part, e.g. a sheet metal part (13, 13'). Said fastening element comprises an axis of symmetry (18), a head piece (14) with a contact surface (22) that comes in contact with the part (13), a fastening section encompassing a thread (15, 15'), and at least one undercut (24, 82) which accommodates the material of the part. The material of the part is pressed against the contact surface and into the undercut by means of a first tool (26-26''''') which is provided with a female die that is suitable for embodying the fastening element. The inventive method and device are characterized in that a local force (K) is applied to the head piece (14) of the fastening element (12, 12') or to the tool (26-26''''') at the side of the axis of symmetry (18) and moves in a circular manner around said axis of symmetry (arrow 43) while performing a relative advancing movement (arrow 28) between the tool (26-26''''') and the fastening element (12, 12'), between which the part (13, 13') is positioned, in order to press the material of the part into the undercut (24, 82).

Disclosed are a method and a device for mounting a fastening element (12) to a part (13), e.g. a sheet metal part, said fastening element comprising a head piece (14) with a tubular rivet section (16) which is disposed concentric to an axis of symmetry (18) of the fastening element (12) or a fastening section (20) of the fastening element (12) and extends into the head piece via a radially extending contact surface (22). The rivet section (16) is guided through the part (12) so as to form a hole in said part, and the rivet section (12) is flanged such that the part is clamped between the contact surface and the flanged rivet section in the area of the hole. The inventive method and device are characterized in that the part is placed above a rivet matrix, and the rivet section is pressed through the part and is then flanged by applying a local force to the head piece of the fastening element, said force moving in circles about the central axis of symmetry, or by applying such a force to the matrix while performing a relative axial advancing movement between the tool applying said force and the matrix.

The invention relates to a functional carrier device consisting of a functional element (12) comprising a shaft part (18), a head part (20), and a rivet sleeve (14). The rivet sleeve (14) can be moved along the shaft element (18) in the axial direction thereof, and the functional element comprises a channel (22) in the transition region between the shaft part (18) and the head part (20), said channel (22) forming a sliding surface for deforming one of the ends of the rivet sleeve (14), and being optionally provided with grooves (24) and/or projections extending in a longitudinal direction. The invention also relates to a tool for use with the functional carrier device, an assembly component, and a method for inserting the functional carrier device into a component (10).

The invention relates to a rivet nut (10) with a base part (12) and a cylindrical rivet section (14), the base part having a central threaded cylinder (16), an annular contact surface (18) that is coaxial to the threaded cylinder in a plane (20) perpendicular to the longitudinal axis (22) of the threaded cylinder, and that has an axially aligned annular groove (24), said groove being arranged radially inside the annular contact surface and radially outside the cylindrical rivet section and said groove blending, on the radially inner side, into the outer surface of the cylindrical rivet section, and antirotation ribs (42) being provided in the area of the annular groove. The invention is characterized in that the annular groove, when seen in an axial cross-sectional plane, has a U-shaped cross-section with a radially outer lateral wall (30) which is relatively steep and which has, at the steepest point (33), an inclination to the center longitudinal axis of the rivet nut in the range of approximately 45° to approximately -20°, preferably of approximately 30° to approximately 0°. The volume of the annular groove is chosen in such a manner that across a range of sheet thicknesses adapted to the respective thread size there is room for the volume of the respective folded region of the rivet section inside the annular recess (80) that is formed by molding the sheet part (60) into the annular groove of the element and that it does not project beyond the side (82) of the molded sheet facing away from the annular contact surface.

The invention relates to a fixing element (700) comprising a fixing section (702) and a tubular stamped and/or riveted section (704). The stamped and/or riveted section is embodied in such a way as to enable the fixing element to be placed on a metal part and the fixing section is embodied in such a way as to enable an object to be placed on the metal part. A bearing surface (708) is provided in the region of the transition between the fixing section and the stamped and/or riveted section, extending in a radial and/or conical manner, said bearing surface optionally exhibiting torsional fixing features (701, 702) and the free front end area (714) of the tubular stamped and/or riveted section is provided with a conical cutting surface (716) which is divergent on the radially inner side in the direction of the free front end area and a rounded impact and traction surface (718) on the radially outer side. The cutting surface and the impact and traction surface meet at a ring-shaped front edge (720) on the free front end of the stamped and/or riveted section. The invention is characterized by the shape of the rounded impact and traction area which prevents shavings from occurring.
摘要:
A functional element arrangement which includes a functional element which is to be mounted on a component, especially but not exclusively on a brittle or non-rigid component made of a material containing cavities or pores, e.g. plastic, wood, metal foams, plastic or metal filled with hollow bodies, or another relatively soft material, selectively embodied as a sandwich construction or as a composite material e.g. in the form of a single layered or multilayered structure comprising, for example, two layers of sheet metal or plastic and a core made of one of the above-mentioned materials. The invention is characterized in that it is provided with an auxiliary assembly element which enables the functional element to be blocked using forming techniques when it is mounted on the component in a riveting process or a stamping and riveting process. The invention is further characterized in that, preferably, at least one device is provided to ensure rotational security between the functional element and the component and/or between the auxiliary assembly element and the component. The invention also relates to a functional element, an auxiliary assembly element, an assembled component and various methods for producing assembled components.
