Method for configuring a mandrel of a riveting tool for blind rivet elements and riveting tool

1. A method for configuring a hand-held riveting tool operated by an electric drive for setting a blind rivet element in a setting operation, the hand-held riveting tool comprising:

a mandrel configured to perform an axial movement so as to perform the setting operation of the blind rivet element, the mandrel comprising a front end position to which the blind rivet element is fitted in at least one of a form-locked manner and a force-locked manner; and

a control unit configured to monitor the axial movement of the mandrel,

the method comprising:

axially moving the mandrel from the front end position into a rear end position, the rear end position being defined at a beginning of the setting operation; and

automatically adjusting the rear end position of the mandrel with respect to the mouthpiece based on a parameter related to the blind rivet element provided to the control unit.

2. The method as recited in claim 1 , wherein the blind rivet element is fitted to the front end position of the mandrel by screwing.

3. The method as recited in claim 1 , wherein the parameter is based on an input provided by a user.

4. The method as recited in claim 3 , wherein the input specified by the user comprises at least one of organizational details of the manufacturer, constructional variables of the blind rivet element, and the rear end position of the mandrel.

5. The method as recited in claim 4 , wherein the control unit is configured to store associations of the organizational details of the manufacturer, the constructional variables of the blind rivet elements, and the rear end position of the mandrel.

6. The method as recited in claim 4 , wherein the constructional variables of the blind rivet element include a blind rivet element length.

7. The method as recited in claim 1 , wherein,

a tag is attached to at least one of the blind rivet element and to a container containing the blind rivet element, the tag being configured to store information from which the parameter can be provided, and

the method further comprises:

reading out the tag by the user via a reader so as to provide the parameter based on the information stored in the tag.

8. The method as recited in claim 7 , wherein the tag is a NFC-tag or a barcode.

9. The method as recited in claim 1 , wherein the parameter is based on a measured variable relating to a force axially moving the mandrel, the force being measured by the hand-held riveting tool.

10. The method as recited in claim 9 , wherein,

a critical value for the measured variable is stored in the control unit, and

the rear end position of the mandrel results from reaching the critical value.

11. A hand-held riveting tool for setting a blind rivet element configured to perform the method as recited in claim 1 , the hand-held riveting tool comprising;

a drive comprising an electric motor;

a mandrel configured to perform an axial movement so as to perform a setting operation of the blind rivet element;

a control unit configured to monitor the axial movement of the mandrel; and

a device configured to automatically determine a rear end position of the mandrel and to automatically adjust itself based on a parameter provided to the control unit.

12. The riveting tool as recited in claim 11 , wherein the device is further configured to record a measured variable which relates to a force acting upon the mandrel.

13. The riveting tool as recited in claim 11 , further comprising:

a device configured to determine a rotational angle position of the electric motor.
