| Abstract(in English) | Large capacity ultrasonic complex vibration sources using multiple 40 and 27 kHz bolt-clamped Langevin type piezo-ceramic (PZT) transducers (BLTs) were proposed and studied on the vibration and welding characteristics, previously. To improve the vibration characteristics of the complex vibration source, an ultrasonic complex vibration source using six 27 kHz 40-mm-diameter BLT transducers with normal and reverse polarities is proposed and studied. The complex vibration source consists of a 2 stepped horn with a welding tip, six driving longitudinal vibration systems with three normal and reverse polarity BLT transducers respectively and a (2, l) mode transverse vibration disk. Two vibration systems with a normal and a reverse polarity BLT transducers respectively are installed in opposite loop positions of the disk. These transducers are connected in parallel without transformer and the transducer pair is driven in anti-phase mode. Three transducer pairs installed in the disk symmetrically are driven in 120° vibration phase difference using an arbitrary waveform generator with variable phase output voltages, three matching transformers and three 500 kW SIT power amplifiers. Almost circular vibration locus was obtained at the welding tip installed in the free edge of the stepped horn installed in the center of the disk. Characteristics of two lapped spot ultrasonic welding of 1.0-mm-thick and 10-mm-wide aluminum plates, and aluminum and copper plate specimens were studied and weld strengths about equal to the material were obtained.A@Using complex vibration, larger and more uniform welded areas and larger weld strength are obtained independent of the welding direction compared with linear vibration. |
