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(shí)，會產(chǎn)生每秒幾萬次的高頻振動，這種達(dá)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(shí)還不能及時(shí)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(jiān)固的分子鏈，達(dá)到焊接的目的，焊接強(qiáng)度能接近于原材料強(qiáng)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(shí)間等三個因素，焊接時(shí)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(shí)，大型超聲波焊接設(shè)備批發(fā)，塑料的熔解量就大，焊接物易變形；若能量小，大型超聲波焊接設(shè)備批發(fā)，則不易焊牢，所加的壓力也不能太**型超聲波焊接設(shè)備批發(fā)。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。大型超聲波焊接設(shè)備批發(fā)</p><div

style="text-indent:25px">超聲波焊接機(jī)的振幅選擇：振幅是超聲波焊接機(jī)中非常重要的參數(shù)之一，它對于摩擦功率的大小有著決定的作用，同時(shí)跟焊接面氧化膜、結(jié)合面的摩擦產(chǎn)熱、塑性流動層等有著非常緊密的聯(lián)系。所以，選擇合適的振幅是非常重要的。振幅的范圍一般在5到256納米，焊接機(jī)的功率越小，振動頻率越高，選擇振幅就要低；當(dāng)焊件較薄時(shí)或者硬度較低時(shí)，需要選擇較低的振幅。之所以這樣是因?yàn)?，振幅的大小直接關(guān)系著接觸面的焊件的移動速度的大小，而相對移動速度大小又決定著摩擦功率、塑性流動和溫度。超聲波焊接機(jī)時(shí)要選擇對合適的振幅范圍，在這里要指出的是，在這個范圍之內(nèi)，選擇大振幅的可以有效的減少焊接的時(shí)間，對于提高工作效率來說是一個好的方法。大型超聲波焊接設(shè)備批發(fā)超聲波焊接的基本原則是，必須有兩塊材料可以在很大的壓力下粘合在一起。</p><div

style="text-indent:25px">高周波與超聲波的區(qū)別！高周波與超聲波是不同的兩個概念，高周波是指頻率大于100Khz的電磁波，超聲波是指頻率超過20千赫茲的聲波。高周波的焊接原理、焊接原理與超聲波也是不一樣的，高周波是利用高頻電磁場使物料內(nèi)部分子間互相激烈碰撞產(chǎn)生高溫達(dá)到焊接和熔接的目的，而超聲波是利用摩擦生熱的原理產(chǎn)生大量的熱量達(dá)到焊接和熔接的目的。高周波應(yīng)用領(lǐng)域較廣，所以目前已有高周波塑料熔接機(jī)、高周波皮塑熔斷機(jī)、高周波折盒壓痕機(jī)、高周波壓花機(jī)、高頻加熱機(jī)等。高周波即高頻波。高周波與超聲波是不同的兩個概念，高周波是指頻率大于100Khz的電磁波，東莞超聲波是指頻率超過20千赫茲的聲波。高周波的焊接原理、熔接原理與超聲波也是不一樣的，高周波是利用高頻電磁場使物料內(nèi)部分子間互相激烈碰撞產(chǎn)生高溫達(dá)到焊接和熔接的目的，而超聲波是利用摩擦生熱的原理產(chǎn)生大量的熱量達(dá)到焊接和熔接的目的。高頻由電子管自激振蕩器產(chǎn)生商頻電磁場，使加工塑膠在上下電極間的高頻電場中，其內(nèi)部分子產(chǎn)生距力運(yùn)動摩擦，在模具的壓力下得到其熔接目的，熔接效果。</p><p style="text-indent:25px">超聲波金屬焊接是利用高頻振動波傳遞到兩個需焊接的金屬表面，在加壓的情況下，使兩個金屬表面相互摩擦而形成分子層之間的熔合，其優(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；缺點(diǎn)是所焊接金屬件不能太厚（一般小于或等于5mm）、焊點(diǎn)位不能太大、需要加壓。設(shè)備種類：1、超聲波焊接 ultrasonic welding：熱塑性塑料在超聲波振動作用下，由于表面分子間摩擦生熱而使兩塊塑料熔接在一起的焊接方法。2、超聲波金屬焊接：超聲波金屬焊接是一種機(jī)械處理過程，在焊接過程中，并無電流在被焊件中流過，也無諸如電焊模式的焊弧產(chǎn)生，由于超聲焊接不存在熱傳導(dǎo)與電阻率等問題，因此對于有色金屬材料來說，無疑是一種理想的金屬焊接設(shè)備系統(tǒng)，對于不同厚度的片材，能有效地進(jìn)行焊接。超聲波焊接機(jī)使用的頻率一般有15khz，20khz，35khz，和40khz。</p><div

認(rèn)為是音波在接觸面進(jìn)行焊接, 其實(shí)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(jī)械后, 通過工件物質(zhì)分子進(jìn)行傳導(dǎo), 聲波在固體中地傳導(dǎo)聲阻遠(yuǎn)小于在空氣中的聲阻, 當(dāng)聲波通過工件接縫時(shí), 縫隙中的聲阻大, 產(chǎn)生的熱能相當(dāng)就大. 溫度首先達(dá)到工件的容點(diǎn), 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, 溫度低不會熔接. 其原理同電工學(xué)中的歐姆定律類似。大型超聲波焊接設(shè)備批發(fā)</p></p><br /><p>文章來源地址:
