Abrégé
A device and the method serve to set a connecting element, in particular a press-in bolt, on a workpiece. By means of a setting unit, a hole punching operation for introducing a hole and, at the same time, a hole-forming operation are carried out, in which an edge of the hole is deep-drawn using an embossing sleeve and a collar is formed. In a second stage, the connecting element is pressed in, the punching and hole-forming operation and the pressing taking place within the same axial axis without the workpiece being laterally displaced relative to the device.

Abrégé
A press-fit connection between a high-strength component and a press-fit element is characterized by a non-circular previously made hole into which the press-fit element having a collar is inserted. Here, the collar is merely upset and pressed against a hole rim without embracing an underside of the component. Preferably, the hole rim is widened in a longitudinal direction such that a form-locking connection acting in opposition to the longitudinal direction is formed. The non-circular hole geometry is produced with the aid of a punch of circular cross sectional geometry, in that a cutter of the punch has leading and recessed cutting regions, with the result that disrupted partial regions are formed.

Process for producing a connecting element as well as connecting element
Richard Bergner Verbindungstechnik GmbH & Co. KG (Allemagne)
Inventeur(s)
Bingeser, Roland
Pramschuefer, Helene
Abrégé
In a method for producing a connecting element, in particular a bolt, a zinc anti-friction coating is applied to a blank made of a metallic base material. Subsequently, the coated blank is deformed in a deformation process to a desired final geometry of the bolt. The deformation process may, in particular, be a thread rolling process. The anti-friction coating is applied in particular by way of a zinc diffusion method. The bolt is in particular an engine bolt, specifically a connecting rod bolt. A bolt of this type has a durability as conventional bolts, but at the same time can be mounted repeatedly by virtue of the formation of the special anti-friction coating without the coefficients of friction increasing above permissible limits.

Dehlke, Klaus
Abrégé
In order to reliably ensure a press-in connection between joining elements, in particular a press-in nut and a pre-punched component, a press-in device contains a die which has a die ring and a die mandrel. The die mandrel is mounted counter to a spring force in the manner of a pilot pin. In addition, the die ring is also mounted counter to a spring force such that a two-stage press-in operation is carried out. Preferably, during a first press-in stage an anti-rotation lock is formed between the press-in nut and the component and in a second press-in stage an axial pull-out prevention measure is formed. To this end, the die mandrel deforms a nut flange.

Device and method for reversibly gripping a bolt-shaped element, in particular a rivet mandrel
Richard Bergner Verbindungstechnik GmbH & Co. KG (Allemagne)
Inventeur(s)
Skolaude, Andreas
Abrégé
The device for reversibly gripping a rivet mandrel has a tension head with a mouthpiece sleeve and a clamping jaw sleeve axially movable in the mouthpiece sleeve and accommodating a plurality of clamping jaws. The clamping jaws reversibly grip the rivet mandrel during an axial displacement of the clamping jaw sleeve and the clamping jaws are furthermore held by an elastic holding element. The jaws are displaceable relative to one another independently of an actuation by the clamping jaw sleeve. This enables improved introduction and gripping of the rivet mandrel, especially for fully automated blind rivet operations, for example with blind rivet robots. Due to the elastic holding of the clamping jaws, wear on one side of the clamping jaws is avoided. Also, a controlled displacement of the clamping jaws independently of the clamping jaw sleeve is provided.

Abrégé
An electric drive for a processing tool, in particular for a rivet setting appliance, has an electric motor connected to an actuating element that is linearly displaceable in an axial direction. A damping element that acts in the axial direction is arranged between the electric motor and the actuating element for impact decoupling of the electric motor from the actuating element. As a result, sudden loads, for example if a rivet mandrel breaks during the blind rivet setting operation, are absorbed in a material-conserving manner.
