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 is a method for producing hollow elements (200), such as nut elements, which are to be mounted on parts generally made of sheet metal, particularly for producing hollow elements having an at least substantially square or rectangular outer contour (202). According to said method, individual elements are cut to size from a profiled member that is provided in the form of a profiled bar or a reel after punching holes into said profiled member, optionally followed by embodying a threaded cylinder (206) using a follow-on composite tool (10) with several workstations (A, B, C, D). The inventive method is characterized in that a penetrating process, a punching process, and a flattening process are carried out in the workstations (A, B, C, D). Also disclosed are hollow elements (200), assembly pieces, and a follow-on composite tool (10).

Ein hohles Befestigungselement zur Anbringung an ein Blechteil, wobei das hohle Befestigungselement einen Kopfteil und einen Nietabschnitt aufweist, der Nietabschnitt über eine ringförmige Anlagefläche für das Blechteil in den Kopfteil übergeht und Verdrehsicherungsmerkmale an der Anlagefläche vorgesehen sind und das hohle Befestigungselement eine Bohrung, beispielsweise eine glatte Zylinderbohrung aufweist, zeichnet sich dadurch aus, dass die ringförmige Anlagefläche konusförmig ist, wobei die Verdrehsicherungsmerkmale an der konusförmigen Anlagefläche ausgebildet sind, und dass ein rohrförmiger Führungsabschnitt konzentrisch zum rohrförmigen Nietabschnitt und radial innerhalb diesem angeordnet ist, wobei zwischen dem Führungsabschnitt und dem Nietabschnitt ein Ringspalt vorgesehen ist und der Führungsabschnitt über das freie Ende des Nietabschnittes hinausragt. Ein entsprechend hergestelltes Zusammenbauteil wird ebenfalls beschrieben und beansprucht.

The invention relates to a method for creating an electrically conductive connection between an electric terminal device having a cavity, such as a cable shoe, and a sheet metal part. According to said method, a hollow fixing element is riveted to the sheet metal part to prevent torsion, thus producing an electrically conductive connection between the fixing element and the sheet metal part and the assembled component is then provided with an electrically non-conductive or poorly conductive protective coating, such as for example a lacquer coating or powder coating. Said method is characterised in that a receptacle for the electric terminal device is configured in the vicinity of the front face of the fixing element, to which the electric terminal device is attached, said receptacle preventing the torsion of the terminal device in relation to the fixing element and the sheet metal part and that a thread forming or cutting screw is screwed through the cavity of the electric terminal device into the hollow fixing element, said screwing action forming or cutting a thread. The invention also relates to a corresponding fixing element and an assembled component that is produced in this manner.

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.

In a method for inserting a bolt element (10) having a head portion (12) and a shaft portion (16) into a sheet metal component (52) the bolt element is passed through the sheet metal component by means of a setting head (38), with its end (100) remote from the head portion at the front, and is riveted to the sheet metal component (52) in the region of its head portion (12) by the cooperation of the setting head with a die (54) arranged at the side of the sheet metal component remote from the setting head (38). The sheet metal component (52) is pierced either by a hole punch or by the specially shaped bolt element (10), by the end of the shaft portion (16) remote from the head portion (12) under the action of the setting head (38), to form a ring collar which is subsequently deformed radially into contact with a groove in the shaft portion. In this arrangement the end (100) of the bolt element (10) which performs the punching work is preferably executed in accordance with the Ka shape of DIN 78.

The invention relates to a joining device (10) which is or which can be fixed to a first structural part (14) at one end (12) by means of a joint (11) which can be produced by a metal-forming technique, preferably a riveted joint. Said joining device also has a receiving area for receiving a pin (64), a nut or another element, for example a bayonet part or a shaft. In an area (18) located at a distance from the aforementioned end (12), the joining device is configured for mounting on or in a second structural part (30). The invention also relates to a combination of a joining device of this type and one (14), two (14, 30) or three structural parts (14, 30, 60) and to a method for producing a joint between a first and a second structural part using said joining device (10).
