Set of interchangeable crimp units

1. A set of interchangeable crimp units for a crimping machine, said crimp units each comprising two die holders and two coupling regions for releasably coupling said die holders with the crimping machine, wherein

said crimp units each comprise

a sensor for at least one of sensing a crimping force or a crimping distance, and

an independent control unit, wherein

said control unit comprises control logic for processing a measurement signal of said sensor, wherein

calibration factors or calibration curves are modelled or stored in the control unit or in a storage unit also integrated into the crimp unit, and

the control unit is designed and configured such that during the use of the crimp unit in the crimping machine, the control unit determines a modified output signal under consideration of the calibration factor or calibration curve so that the crimp unit supplies an adapted or modified output signal, wherein in the modified signal, the calibration factor or calibration curve is already considered.

2. The set of interchangeable crimp units of claim 1 , wherein each of said crimp units comprises a protective cover.

3. The set of interchangeable crimp units of claim 2 , wherein said protective cover is at least partially built by a transparent or translucent material.

4. The set of interchangeable crimp units of claim 1 , wherein a first die holder of said two die holders of each of said crimping units is guided by a second die holder of said two die holders of each of said crimping units.

5. The set of interchangeable crimp units of claim 4 , wherein said first die holder comprises a guiding pin extending through a guiding recess of said second die holder.

6. The set of interchangeable crimp units of claim 5 , wherein said first or second die holder comprises another guiding pin and said two guiding pins are located on opposing sides of a nest of a die being held by said die holders.

7. The set of interchangeable crimp units of claim 6 , wherein said two guiding pins have different lengths wherein the longer guiding pin of said two guiding pins enters into a respective guiding recess before the shorter guiding pin of said two guiding pins enters into a respective guiding recess.

8. The set of interchangeable crimp units of claim 1 , wherein said sensor for at least one of sensing a crimping force or a crimping distance is located centrally behind one of said die holders when seen along a crimping axis.

9. The set of interchangeable crimp units of claim 1 , wherein said die holders are designed and configured for holding a die having a plurality of nests.

10. The set of interchangeable crimp units of claim 1 , wherein at least one of at least one interface or at least one plug is provided at each of said crimp units wherein said interface or plug supplies said sensor with electrical energy or transfers a measurement signal of said sensor.

11. The set of interchangeable crimp units of claim 10 , wherein said crimp units have at least one of differing geometries or sensors and at least one of unique interfaces or plugs.

12. The set of interchangeable crimp units of claim 1 , wherein said crimp units have at least one of differing coupling regions, sensors, geometries, die holders, plugs and interfaces.

13. The set of interchangeable crimp units of claim 1 , wherein said sensors of said crimp units have differing sensitivities.

14. A crimping machine comprising a set of interchangeable crimp units of claim 1 .

15. The crimping machine of claim 14 , wherein said control unit is provided, said control unit comprising control logic for determining crimping forces or crimping displacements from measurement signals of said sensors of said crimp units of said set of interchangeable crimp units under consideration of calibration factors or calibration curves.

16. The crimping machine of claim 15 , wherein said control logic uses at least one of differing calibration factors or calibration curves for each of said crimp units of said set of interchangeable crimp units.

17. The crimping machine of claim 16 , wherein said control logic uses at least one of differing calibration factors or calibration curves for different nests of a die held by said die holders.
