With automatic feeder widely matched to punch production, abnormal feeding, mis-feeding, sheet stacking and offset feedi

1.Accident overview: A hardware factory adopts unlinked ordinary feeder and punch. Raw material warpage caused double-layer sheet feeding into mold, equipment lacked detection function and finished stamping. Instant overload burst expensive precision mold, flying fragments hurt nearby worker, direct economic loss over 80 thousand RMB.

2.Root analysis: No linkage signal between feeder and punch, no thickness identification device, abnormal feeding cannot stop host stroke, equipment design defect is primary cause.

3.Qiaosen improvement: Built-in thickness sensing + linkage interlock, double-layer material detected to lock punch immediately, zero mold burst risk from stacked feeding.

1.Accident overview: Feeder clamping loosened leads empty feeding and material deviation. Traditional punch runs normally without feedback, hollow stamping causes mold core collision and slide component deformation, whole production line suspended for overhaul.

2.Root analysis: No real-time feeding position monitoring, feeder and punch work out of sync, lacking automatic stop protection mechanism.

3.Qiaosen improvement: Position sensor tracks material traveling track, empty feed or deflection triggers whole-line shutdown, prevent idle collision damage.
