Customer: Shenzhen Hardware Products Co., Ltd.
Name: World Press
Model: JH26-160
Cause of failure: running start alarm
Fault analysis: a brief introduction: the motor drives the flywheel, the flywheel through the shaft and pinion drive gear, the big gear through the clutch to drive the crankshaft, the crankshaft drives the connecting rod to make the slide block work. The number of strokes per minute and the movement curve of the slider are all fixed.

The workshop press is a universal punch press machine, which can realize all kinds of cold stamping process, such as punching, bending, shallow drawing, etc.. According to the scene on jump alarm, open the shell discovery module has obvious rectifier burn, after the restoration of electricity that finishing thyristor module driving voltage is not normal, detection control circuit of optocoupler has been bad, after the failure to lift replacement. The analysis may be outside of the motor coil short circuit burned out lead inverter rectifier control circuit abnormality alarm.
The common faults of the frequency converter of the punch press is no display, lack of phase, over current, over current, over voltage, under voltage, over heat, over load, ground, parameter error, display without output.
Module damage, error, etc.. Please call the service hotline 0755-28916839, 13640994287, we have a professional customer service staff to quickly respond to your needs.
