  • Self-piercing rivet setting machine
    Patent number: 8434215
    Abstract: A self-piercing rivet setting machine comprises a C-shaped arm and a receiver section disposed at one end of the C-shaped arm to receive a self-piercing rivet fed from a feeder. The receiver section has a rivet-reach detection sensor to detect the presence or absence of a self-piercing rivet in a driving chamber therein. If the rivet-reach detection sensor detects the absence of any self-piercing rivet in the driving chamber, the sensor outputs a signal to prevent a punch from being driven.
