Abstract
A riveting device for setting a blind rivet element includes a mandrel, a first motor comprising a first operative connection to the mandrel, and a second motor comprising a second operative connection to the mandrel. The mandrel is configured to have a rotational movement be transmitted thereto to screw the mandrel into the blind rivet element, and to be retracted into the riveting device by a retraction movement to produce an at least partial plastic deformation of the blind rivet element. The first motor transmits the rotational movement to the mandrel via the first operative connection. The second motor transmits the retraction movement to the mandrel via the second operative connection.

A riveting device for setting a blind rivet element, the riving device comprising:
- a mandrel configured,
- to have a rotational movement be transmitted thereto to screw the mandrel into the blind rivet element, and
- to be retracted into the riveting device by a retraction movement to produce an at least partial plastic deformation of the blind rivet element;
- a first motor comprising a first operative connection to the mandrel, the first motor being configured to transmit the rotational movement to the mandrel via the first operative connection;
- and
- a second motor comprising a second operative connection to the mandrel, the second motor being configured to transmit the retraction movement to the mandrel via the second operative connection.
A method for operating a riveting device for setting a blind rivet element, wherein the riveting device comprises:
- a mandrel configured,
- to have a rotational movement be transmitted thereto to screw the mandrel into the blind rivet element, and
- to be retracted into the riveting device by a retraction movement to produce an at least partial plastic deformation of the blind rivet element;
- a first motor comprising a first operative connection to the mandrel, the first motor being configured to transmit the rotational movement to the mandrel via the first operative connection;
- and
- a second motor comprising a second operative connection to the mandrel, the second motor being configured to transmit the retraction movement to the mandrel via the second operative connection,
- the method comprising:
- activating the first motor to transmit the rotational movement to the mandrel via the first operative connection to the mandrel so as to screw the mandrel into the blind rivet element;
- deactivating the first motor;
- and
- activating the second motor to transmit the retraction movement to the mandrel via the second operative connection to the mandrel so as to produce the at least partial plastic deformation of the blind rivet element.
