Nietmaschinen und insbesondere System und Verfahren zum Synchronisieren von zwei Nietmaschinen

摘要

A rivet gun system includes a rivet gun frame having two ends. A die is coupled to one end, and a force sensor coupled to the rivet gun frame. The force sensor detects force applied to the die and generates a force signal in response to the force. A holding coil defines a channel within the rivet gun frame and generates an electromagnetic force along the channel. The channel includes an end defined by an end stop and an end defined by the die. A main coil further defines the channel between the holding coil and the die. The main coil also generates an electromagnetic force along the channel. A plunger slides through the channel in response to the electromagnetic forces. A force sensor electronics controller receives the force signal from the force sensor and activates the holding coil and the main coil in response to the force signal above an activation threshold.
