摘要:
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.

The invention concerns a functional element, in particular a bolt, consisting of a shank portion (14) and a head portion (16) designed to be assembled riveted with a plate element, in particular a sheet metal part. The invention is characterised in that the head portion (16) is hollow and has practically the same external diameter as the shank portion. When mounted, the hollow head portion (16) of the functional element (10) forms a riveting edge (37) on one side of the sheet metal part and an annular groove (52) on the other side of the sheet metal part, the annular groove (52) acting as a flange. The invention further concerns a method for fixing the functional element in a sheet metal part and the resulting assembling element (16), as well as a matrix and a swaging assembly.

A method for placing a functional element, especially a fastening element, in an especially liquid-tight and/or gastight manner, on a metal part. The inventive method is characterized in that a functional element provided with a hollow head segment is pressed against the metal part (212) which is supported by a die (214) and the metal material is deformed into an undercut (324) by deforming the head segment when simultaneous deformation of the hollow head segment occurs and the metal part is shaped in a forming area defined by parts (216) of the die (214).Said parts (216) are kept in a stationary position during the forming process but are partially removed from the die to enable the functional element which is placed on the metal part (212) to be extracted therefrom. The invention also relates to a die, a functional element, an assembly element and a die arrangement.

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).

Die Erfindung betrifft ein Verfahren zur insbesondere flüssigkeits- und/oder gasdichten Anbringung eines Funktionselementes (10, 210, 410), insbesondere eines Befestigungselementes, an einem Blechteil (12, 212, 412), bei dem das Funktionselement (10, 210, 410) gegen das durch eine Matrize (14, 114, 214, 414) abgestützte Blechteil (12, 212, 412) gepreßt und Blechmaterial (13) mittels wenigstens eines beweglich gelagerten Formteils (16, 116, 216, 416) der Matrize (14, 114, 214, 414) in eine Hinterschneidung (18) des Funktionselementes (10, 210, 410) gedrückt wird.
摘要:
Ein Befestigungselement (10) wird beansprucht mit einer hohlen Vertiefung (14) an einer Stirnseite (12), mit mehreren Hinterschneidungen (41) bildenden Vorsprüngen (40) an einer die hohle Vertiefung (14) umgebenden Seitenwand (15) und mit mehreren eingedrückten Bereichen (38) an einer Anlagefläche (12) der genannten Stirnseite an Stellen, die den genannten Vorsprüngen (40) entsprechen. Ein Verfahren zum Herstellen dieses Befestigungselementes (10) zeichnet sich dadurch aus, daß die Vorsprünge (40) durch das Eindrücken der eingedrückten Bereiche hergestellt werden, das beispielsweise durch Kaltschlagen erfolgt.

Supply system (10) for the delivery of elements (130, 150) to one or more users (12) comprising a forwarding device (76, 76', 76'') which supplies the elements from a stored quantity (78) to a sorting device (70, 70'), which only permits elements having a predetermined position to pass and with a transport device (72, 72'), which transports the positionally correctly sorted elements (130, 150) to the user (12), characterized in that the forwarding device (76, 76', 76'') forms part of a basic module while the sorting device (70, 70') and the transport device (72, 72') belong to an interchangeable module. In this way the components of the supply system (10) can be manufactured and used more rationally, whereby the investment costs sink and can be more quickly amortized.
摘要:
A method of riveting a plurality of panels utilizing a fastener which may then be used to attach a further element to the panel assembly and wherein the fastener is first permanently attached to a first panel for a later attachment to a second or plurality of panels to form the fastener and panel assembly. The fastener is attached to the first panel by piercing a tubular barrel portion through the panel and affixing the first panel in an annular groove in a flange portion surrounding the barrel portion. The groove includes radial ribs preventing rotation of the fastener in the first panel and a radial rib is deformed in an outer surface of the barrel portion preventing pull-out of the fastener. The second and further panels are pre-pierced with a conical lip surrounding the panel opening and received on the barrel portion of the fastener with the conical lip facing the first panel. An annular recess is formed in the first panel which recedes the conical lip of the second panel and the free end of the barrel portion is deformed over the second panel, flattening the conical lip radially inwardly against the barrel portion, forming a secure mechanical interlock between the fastener and the panel assembly.
