This is repeated until the Do not differentiate or only minimally differentiate the measured remaining press paths, the pressing tool 3 has therefore settled.
  • the one after that determined residual press path is stored in the memory chip 100 accepted. It is characteristic of the pressing tool in question 3. Due to manufacturing tolerances Pressing tools 3 of the same size, different residual press paths surrender.
  • the calibration described above ensures that the Drive motor 5 in a defined, for that Pressing tool 3 characteristic final pressing position switched off becomes.
  • the jaw closing sensor 54 is released during the pressing process the distance measurement for the stored remaining press path, whereby this by counting the pulses detected by the speed sensor 25 happens. After driving the remaining press path, the drive motor 5 switched off via the switch-off element 66.
  • an automatic selection of the appropriate one can be made Restpreßweg done in such a way that during the Pressing the compression resistance at a certain Point of the pressing path and its value as a selection criterion is used.
  • This can be the case with the present pressing device 1 happen in such a way that each one is characteristic Deviation from curve 79 is determined at the specific location and the measure of the deviation as a selection criterion is used.

  • the remaining press path or the remaining press paths be stored in the memory chip 100. Instead there is the possibility of storing the remaining press paths on the drive part 2 and here in particular in the microprocessor 63. In this case, the remaining press path or the group of remaining press paths by coding based on resistor 50 or the memory chip 100 driven. However, then be assured that for the respective press tool to be connected 3 actually a suitable residual press path or one Group of residual press paths is stored. Comes a press tool 3 for use, for which there is still no residual pressing path or no group of residual press paths is stored, should the calibration process described above - be it using the Drive part 2, be it with the help of a special calibration device - be made up for.
