、換能器通過逆壓電效應(yīng)將來自于發(fā)生器的超聲頻電壓轉(zhuǎn)化為同頻率的超聲機(jī)械振動。它由夾于兩金屬（通常是鈦）塊之間的若干壓電陶瓷片組成。片與片之間有一薄金屬板形成電極。在正弦電信號經(jīng)由電極提供給換能器時(shí)，壓電片膨脹和收縮，產(chǎn)生15~20 μm的軸向峰到峰運(yùn)動。超聲波換能器是精密設(shè)備，應(yīng)小心處理。2 超聲波變幅桿：變幅桿有兩個(gè)作用。其主要作用是放大換能器端部產(chǎn)生的機(jī)械振動并將振動傳給焊頭。另一作用是提供固定套件于焊接壓力機(jī)上的位置。在換能器施加超聲能量時(shí)，變幅桿也膨脹和收縮。與焊接套件中的其它零件一樣，變幅桿是調(diào)諧裝置，因而它也必須在特定頻率共振以便將超聲能量從換能器傳至焊頭。為了有效地發(fā)揮作用，變幅桿必須是超聲波在其制造材質(zhì)中的半波長或半波長的整數(shù)倍。一般為半波長。深圳螺柱超聲波焊接設(shè)備哪家好超聲波金屬焊接優(yōu)點(diǎn)在于快速、節(jié)能、熔合強(qiáng)度高、導(dǎo)電性好、無火花、接近冷態(tài)加工。</p><div
