The invention relates to a method for producing hollow body elements (200), for example, nut elements which are applied to components which are normally made of steel (280), in particular, for producing hollow body elements having an essentially quadratic or rectangular external profile (202). Said method consists of cutting individual elements of a profile in the form of a profile rod (1) or a winding after holes (204) have previously been stamped in the profile, a threaded cylinder (206) is subsequently, optionally, formed using a follow-on composite tool (10) which consists of several working stations. The invention is characterised in that a penetrating process and a punching process are carried out in the working station. The invention also relates to hollow body elements (200), components, follow-on composite tools (10) and rolling mills (600, 602).

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 method for transferring fixing elements to punching heads (20) in a press (10), for pressing into plate-shaped workpieces (18), for example in the production of shaped sheet parts. Said fixing elements are transferred especially in transfer tools, being guided to the press (10) by a conveying device or a sorting and conveying device (26) via a guiding element (30) such as a guide channel, guide tube or guide rail. The transfer system is characterised in that the fixing elements are transported by the conveying device or the sorting and conveying device (26) into the lower part of a tool (16) or the upper part of a tool (12) of the press and optionally, once they have been transferred to the other tool part, i.e. the upper part of the tool (12) or the lower part of the tool (16), are transported into a distributor station (38) which feeds the elements to the individual punching heads (20). The invention also relates to devices for transferring fixing elements to punching heads (20).

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.

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).

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).

The invention relates to a method for producing hollow bodies (11, 211, 411) such as nut elements to be fastened to components (13, 213, 413) that usually consist of sheet metal. The invention especially relates to a method for producing hollow bodies with an at least substantially square or rectangular outline by cutting individual bodies from a profile (10, 210, 410) in the form of a profile rod or a reel after respective holes (98, 298, 498) have been punched into the profile, and optionally afterwards producing a threaded cylinder (110, 310, 510). The inventive method is further characterized in that before or after the punching of the profile a passage treatment is carried out in order to produce a cylindrical or annular projection (36, 236, 436), concentric to the punching or the intended punching, on the side (12, 212, 412) of the profile facing the component by flow of material. The projection is optionally shaped to an annular punched section in an additional molding cycle. The invention further relates to various hollow bodies, assembly units and molds for producing said hollow bodies.
