SYSTEM FOR CONTROLLING AN ULTRASONIC CONVERTER FOR A DEVICE FOR ULTRASONIC VIBRO-IMPACT METAL PROCESSING

WIPO Patent Application WO/2005/060014

A1

The invention relates to ultrasonic engineering, in particular to electronic system for controlling an ultrasonic converter used in a device for ultrasonic vibro-impact metal processing. The inventive system comprises, in particular a control unit, a power amplifier, a feedback transformer and a piezo-electrical converter provided with impact elements. In addition, said system comprises a driver and a closing key, a generator and a cut-off key, a resonance circuit Q-factor being also specified. Said invention makes it possible to increase the stability of resonance frequency tuning under widely variable impact loading conditions and simultaneously maintain the oscillation amplitude of the converter at a specified level.
