Abstract: 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.

Abstract: A setting unit and a method for setting a connecting element on a work piece. The setting unit has a hold-down clamp. A punch is displaceably mounted in the hold-down clamp, is drivable in a feed direction by way of a plunger and has a front punch head, and a punch sleeve which surrounds the punch head. The punch sleeve is movable together with the punch in the feed direction to a first stroke position. The punch head is movable relative to the punch sleeve to a second stroke position such that it is possible to carry out both a hole punching operation and a setting operation by way of the one punch in connection with the punch sleeve.

Abstract: A drive unit is configured for a stamping rivet setting device and has an electric direct drive which contains motor components that concentrically surround a control element which can be linearly moved in the axial direction. In order to absorb the required torques while allowing a compact construction of the device, in particular in relation to a component side, a drive housing has an asymmetrical configuration in a connecting region between a main part and a guide part in which the control element is guided, for the purpose of asymmetrical torque transmission. In addition or alternatively thereto, the highly compact construction achieves an efficient cooling by an inner cooling unit, in particular air flowing through a free inner space in which the motor components are arranged.

Abstract: A device for setting a connecting element on a workpiece includes a setting unit having a setting head which is movable in a feed direction into a working position, the connecting element can be fastened on the workpiece by the setting head, and a feed unit can feed the connecting element to the setting head. The feed unit is movable in the feed direction from an initial position into an intermediate position for transferring a connecting element to the setting head. A method for setting a connecting element on a workpiece by using the device is also provided.

Abstract: A feed unit is used to feed connection elements from a receiving position to a transfer position along a feed direction. The feed unit has a receiving part to which each connection element can be fed individually. A head piece is movably mounted in the receiving part and has a receiving region for the nuts, and a thrust unit to move the head piece. The head piece is rotated from a first rotational position into a second rotational position, being reached in an intermediate position, by a rotary device. A slider element moves relative to the head piece out of the intermediate position into a transfer position within the head piece such that the nuts are brought out of the head piece into the transfer position. The rotary device has a mechanical forced guidance unit which includes a control sleeve with a curved path into which a control element engages.

Abstract: The aim is to allow a disposal of scrap mandrels for a blind rivet setting tool directly on a robot hand, which is secured to the blind rivet setting tool. A specially configured mandrel container is provided which has a housing with a receiving volume for the scrap mandrels. A filling nozzle reaches into the receiving volume to a central region of the receiving volume. In this manner, the scrap mandrel container can be filled in a position-independent manner without the danger of an outlet opening of the filling nozzle being closed by scrap mandrels.

Abstract: 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.

Abstract: 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.

Abstract: In order to ensure that the process of setting a blind rivet is reliable, during the setting operation a rivet mandrel is gripped by gripping jaws of a tension head and is pulled in the axial direction for deforming a rivet sleeve. The tension head and the rivet mandrel, in this case, are matched to one another in such a manner that the gripping jaws initially slide along a gripping portion along the rivet mandrel in their closed position until they reach a predetermined tension position, which is defined in particular by a stop, from which the necessary tensile force for the deforming of the rivet sleeve is first transferred onto the rivet mandrel.

Abstract: A magazine for a rivet supply appliance, for accommodating a plurality of rivets disposed in series in a tubular housing, is distinguished by a substantially rectangular inner cross-section, having two opposing longitudinal walls of equal length and two opposing transverse walls, of which one is longer than the other, and an offset is realized within the cross-section by the transitions from the longer transverse wall to the longitudinal walls.
