A riveting system is operable to join two or more workplaces with a rivet. In another aspect of the present invention, a self-piercing rivet is employed. Still another aspect of the present invention employs an electronic control unit and one or more sensors to determine a riveting characteristic and/or an actuator characteristic.

Riveting system and process for forming a riveted joint

A fastening element (), in particular for blind riveting, has a setting head (), a deformation segment () and a shank end (). The deformation segment () is arranged between the setting head () and the shank end (). The fastening element () is hollow, optionally having a mandrel () inside the fastening element (). The mandrel includes a head () and a foot () at least tension-resistantly connected to the shank end (). The shank end () includes a punching edge () extending substantially along the outermost periphery of the shank end (). Also identified are a process for setting the fastening element (), a riveted connection to the fastening element (), a device for setting the fastening element (), an employment of the riveted connection obtained, and a die suitable for setting the fastening element ().

Self-piercing rivet, process and device for setting a rivet element, and employment thereof

The invention relates to a conveyor for elongate components () designed with a head and a shank. The conveyor comprises a feed arrangement (). The feed arrangement () comprises a transfer arrangement () with a transfer region () in which a component () can be positioned. In the transfer region (), a feed duct () having a head guiding duct () and a shank guiding duct () passes into a conveying duct (). The transfer arrangement () comprises at least one catch unit (). The catch unit () comprises at least one catch element (). The catch element () is arranged opposite the head guiding duct () and penetrates at least partially therein. It can be deflected from the head guiding duct () against a spring force.

Method of operating a rivet machine

A feed device for fastening elements with low length-to-diameter ratio has a hollow clamp into which individual fastening elements are inserted through a feed channel. The clamp has an internal pocket for pre-positioning a fastening element. A piston moves through the feed channel to engage the fastening element and to open the clamp to release the fastening element for further movement by the piston.

A method of manufacturing, using a riveting system, is operable to join two or more workpieces with a rivet. In another aspect of the present invention, a self-piercing rivet is employed. Still another aspect of the present invention employs an electronic control unit and one or more sensors to determine a riveting characteristic and/or an actuator characteristic.

Conveyor for elongate components designed with a head and a shank

A through-hole self-piercing rivet is assembled with two metal plates and to retain the plates together as a workpiece When the rivet is to be removed, a pin, such as a contact pin is attached to the rivet by fusion, or a pin, such as a threaded mandrel is attached threadedly to the rivet. The contact pin or the threaded mandrel is withdrawn from the workpiece to thereby withdraw the attached rivet from the workpiece. Devices and provide facility for effecting the attachment of the contact pin and the threaded mandrel respectively, with the rivet and for the extraction of the rivet from the workpiece

Methods of removing self-piercing rivets set into a workpiece and devices for implementing the methods

A method as well as an apparatus manufactures a punch riveted joint, wherein at least two layers are pressed by a holding-down device against the die and a rivet, in particular a semitubular rivet, is provided for joining the layers. The holding-down device is connected by a coupling unit to the punch in such a way that during a punch riveting operation a coupling of the holding-down device to the punch may be varied between a substantially rigid coupling state and an uncoupled state.

Process and device for joining by punching and riveting

A punch rivet ( ) has a cutting edge ( ) which is arranged on the end face of its rivet shank ( ) and is formed in the cutting region by an outer face ( ) extending parallel to the axis and a conical inner face ( ) of the rivet shank ( ). The outer face ( ) extends continuously parallel to the axis over the entire rivet shank ( ) and the punch rivet ( ) is provided with the same cutting edges ( ) on either side in an axially symmetrical design in the form of a tube.

Punch rivet, riveted joints produced with it, riveting tool and method of producing a riveted joint

The invention relates to a coated metal fastener that is prepared by electrogalvanically coating a metal fastener with a layer of tin and zinc mixed crystals, wherein the tin is from about 50 to about 90% by weight of the mixed crystals layer. The fastener plated with the tin and zinc alloy layer has a number of unexpected properties, including stability at higher temperatures than expected, which is important for retaining the strength of a vehicle joint secured with the fastener during subsequent finishing operations; retention of electrical conductivity, which makes the fastener suitable for use as a grounding member; and resistance to galvanic corrosion when the fastener joins metals of differing electrode potential.
