style="text-indent:25px">焊接工藝對(duì)加壓系統(tǒng)的要求：(1)穩(wěn)定性：焊接壓力對(duì)超聲焊接質(zhì)量有較大影響。就超聲波焊接而言,接頭質(zhì)量與輸入到焊件中的能量是密切相關(guān)的，這個(gè)能量可表達(dá)為:能量=振幅 x壓力 x時(shí)間。所以壓力的波動(dòng)會(huì)造成焊接質(zhì)量的不穩(wěn)定,如果焊機(jī)采用變幅桿比較大的聲學(xué)系統(tǒng),則焊接質(zhì)量對(duì)壓力的波動(dòng)更為敏感。所以焊接工藝要求氣動(dòng)系統(tǒng)的工作穩(wěn)定性。(2)氣缸活塞運(yùn)動(dòng)速度可調(diào)：為了實(shí)現(xiàn)焊接，氣缸活塞帶動(dòng)聲學(xué)系統(tǒng)上下運(yùn)動(dòng)。就焊接工藝而言.上下兩種運(yùn)動(dòng)速度是不同的。由于工件種類、尺寸的不同，焊接壓力的建立也要做相應(yīng)變化。對(duì)于特定工件，壓力建立太慢.效率較低;而壓力建立太快又會(huì)造成,溶體塑性形變太快. 導(dǎo)致材料分子噴濺到界面。因而要求下降速度要可調(diào)，同時(shí)為提高焊接效率、減少空耗時(shí)間. 聲學(xué)系統(tǒng)提起活塞時(shí)盡量短些.由于回抽速度對(duì)質(zhì)量無(wú)影響·所以可維持一定的較快速度，來(lái)保證焊接效率。超聲波焊頭是焊接套件中向待焊零件提供能量的部分。</p><div
