Automotive Stamping Press: Data Reveals Design Weakness
Nissan Motors, Smyrna, TN - Repetitive breakdowns of the transfer drive (moves parts through) on a stamping press were restricting production. The press manufacturer said the machine was designed for 18 strokes per minute but running it faster than 10 spm caused drive component failures. Was the press under designed? How much torque was the transfer drive shaft actually experiencing?
Binsfeld Engineering installed a torque sensitive Micro-Measurements strain gage and telemetry system on the transfer driveshaft. Live data recorded during actual production verified that operating loads greatly exceeded design estimates when the transfer mechanism changed directions. The press manufacturer was held accountable for redesign based on the actual torque measurements.
