焊接原理上理解誤區(qū)：有相當(dāng)一部分從事多年超聲波焊接方面的人員. 對超聲能量地傳遞有一種誤解, 認為是音波在接觸面進行焊接, 其實這是一種誤解, 真正的超聲波焊接原理是: 換能器把電能轉(zhuǎn)換為機械后, 通過工件物質(zhì)分子進行傳導(dǎo), 聲波在固體中地傳導(dǎo)聲阻遠小于在空氣中的聲阻, 當(dāng)聲波通過工件接縫時, 縫隙中的聲阻大，金屬超聲波焊接設(shè)備廠家, 產(chǎn)生的熱能相當(dāng)就大. 溫度首先達到工件的容點, 再加上一定的壓力, 使接縫熔接. 而工件的其它部分由于熱阻小，金屬超聲波焊接設(shè)備廠家，金屬超聲波焊接設(shè)備廠家, 溫度低不會熔接. 其原理同電工學(xué)中的歐姆定律類似。超聲波頻率低就會產(chǎn)生噪音，當(dāng)頻率低于20khz時，超聲波焊接時噪音變得很大。金屬超聲波焊接設(shè)備廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">超聲波塑料焊接原理：超聲波作用于熱塑性的塑料接觸面時，會產(chǎn)生每秒幾萬次的高頻振動，這種達到一定振幅的高頻振動，通過上焊件把超聲能量傳送到焊區(qū)，由于焊區(qū)即兩個焊接的交界面處聲阻大，因此會產(chǎn)生局部高溫。又由于塑料導(dǎo)熱性差，一時還不能及時散發(fā)，聚集在焊區(qū)，致使兩個塑料的接觸面迅速熔化，加上一定壓力后，使其融合成一體。當(dāng)超聲波停止作用后，讓壓力持續(xù)幾秒鐘，使其凝固成型，這樣就形成一個堅固的分子鏈，達到焊接的目的，焊接強度能接近于原材料強度。超聲波塑料焊接的好壞取決于換能器焊頭的振幅，所加壓力及焊接時間等三個因素，焊接時間和焊頭壓力是可以調(diào)節(jié)的，振幅由換能器和變幅桿決定。這三個量相互作用有個適宜值，能量超過適宜值時，塑料的熔解量就大，焊接物易變形；若能量小，則不易焊牢，所加的壓力也不能太大。這個好佳壓力是焊接部分的邊長與邊緣每1mm的好佳壓力之積北京三軸超聲波焊接設(shè)備生產(chǎn)廠家隨著塑料及復(fù)合材料的普遍應(yīng)用.人們越來越關(guān)心它們的拼接問題。</p><div

style="text-indent:25px">超聲波焊接設(shè)備原理:當(dāng)超聲波作用于熱塑性的塑料接觸面時，會產(chǎn)生每秒幾萬次的高頻振動，這種達到一定振幅的高頻振動，通過上焊件把超聲能量傳送到焊區(qū)，由于焊區(qū)即兩個焊接的交界面處聲阻大，因此會產(chǎn)生局部高溫。又由于塑料導(dǎo)熱性差，一時還不能及時散發(fā)，聚集在焊區(qū)，致使兩個塑料的接觸面迅速熔化，加上一定壓力后，使其融合成一體。當(dāng)超聲波停止作用后，讓壓力持續(xù)幾秒鐘，使其凝固成型，這樣就形成一個堅固的分子鏈，達到焊接的目的，焊接強度能接近于原材料強度。超聲波塑料焊接的好壞取決于換能器焊頭的振幅，所加壓力及焊接時間等三個因素，焊接時間和焊頭壓力是可以調(diào)節(jié)的，振幅由換能器和變幅桿決定。這三個量相互作用有個適宜值，能量超過適宜值時，塑料的熔解量就大，焊接物易變形；若能量小，則不易焊牢，所加的壓力也不能太大。這個較佳壓力是焊接部分的邊長與邊緣每1mm的較佳壓力之積。當(dāng)超聲波在介質(zhì)中傳播時，由于超聲波與介質(zhì)的相互作用，使介質(zhì)發(fā)生物理的和化學(xué)的變化。</p><div

style="text-indent:25px">超聲波焊接基本思想是在壓力下夾緊工件時將工件磨擦，以形成粘合。工件放置在鐵砧上，鐵砧上有細小的脊部，隆起的細脊被咬入材料中，在焊接過程中將其固定到位。然后將超聲波工具降低到工件上，在壓力下夾緊它們并產(chǎn)生所需的摩擦動作。對于大多數(shù)焊接操作，該工具以20千赫茲的頻率振動，對于低功率應(yīng)用，該工具以大約40千赫茲振動。該過程較初發(fā)現(xiàn)于1963年，當(dāng)時Sonics＆Materials Inc.的創(chuàng)始人Robert Soloff開始使用超聲探頭進行實驗。通過實驗，Soloff發(fā)現(xiàn)聲波不受其他塑料焊接方式的限制。在此發(fā)現(xiàn)之后，Soloff繼續(xù)為Ideal Toy公司的工程師創(chuàng)建了靠前臺超聲波焊接機。金屬超聲波焊接設(shè)備廠家</p><p
