Definitions

  • the invention relates to a rivet setting tool with an electric drive motor, at least one rivet setting device driven by the drive motor with at least one rechargeable battery to power the Drive motor and with a circuit for regulating the power supply to the drive motor.

It turns out to be problematic that the power consumption of the rivet setting tools is quite high. The rechargeable Batteries therefore empty very quickly. It therefore often happens that the voltage of the rechargeable batteries during a rivet setting process has dropped so much that the rivet setting tool stops. Since it is in the middle is in the rivet setting process, this often led to jamming or Block the rivet setting tool. Usually the rivet is still in the Rivet setting tool and must be removed with great effort.
