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(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, 縫隙中的聲阻大, 產(chǎn)生的熱能相當(dāng)就大，廣州手動超聲波焊接設(shè)備銷售. 溫度首先達(dá)到工件的容點(diǎn), 再加上一定的壓力，廣州手動超聲波焊接設(shè)備銷售, 使接縫熔接，廣州手動超聲波焊接設(shè)備銷售. 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。高周波是指頻率大于100Khz的電磁波。廣州手動超聲波焊接設(shè)備銷售</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="廣州手動超聲波焊接設(shè)備銷售,超聲波焊接設(shè)備"

style="text-indent:25px">隨著塑料及復(fù)合材料的較廣應(yīng)用.人們越來越關(guān)心它們的拼接問題。就結(jié)合表面加熱方法而言,超聲波焊接的強(qiáng)度是好高的也是好靈活的。焊接質(zhì)量的好壞不僅與功率、超聲發(fā)生器特性、超聲波焊接工藝參數(shù)有關(guān)·而且還與加壓系統(tǒng)的特性有關(guān)設(shè)計(jì)一套性能良好的氣動加壓系統(tǒng)是實(shí)現(xiàn)良好焊接所必需的。超聲波塑料焊接機(jī)結(jié)構(gòu)：一般地講,超聲波塑料焊接機(jī)由三大部分組成:超聲波發(fā)生器、聲學(xué)系統(tǒng)和加壓系統(tǒng)。超聲波發(fā)生器主要是將50Hz的工頻電轉(zhuǎn)換成超聲頻的交流用以激勵聲學(xué)系統(tǒng);聲學(xué)系統(tǒng)將電能轉(zhuǎn)化為聲能.進(jìn)而轉(zhuǎn)化成熱能.使塑料件在接合處熔于一體。上海全自動超聲波焊接設(shè)備批發(fā)15khz超聲波機(jī)器的換能器一般為倒錐形。</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(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(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。</p><p style="text-indent:25px">焊接優(yōu)點(diǎn)：1、超聲波塑料焊接優(yōu)點(diǎn)：焊接速度快，焊接強(qiáng)度高、密封性好；取代傳統(tǒng)的焊接/粘接工藝，成本低廉，清潔無污染且不會損傷工件；焊接過程穩(wěn)定，所有焊接參數(shù)均可通過軟件系統(tǒng)進(jìn)行追蹤監(jiān)控，一旦發(fā)現(xiàn)故障很容易進(jìn)行排除和維護(hù)。2、超聲波金屬焊接優(yōu)點(diǎn)： 1）、焊接材料不熔融，不脆弱金屬特性。2）、焊接后導(dǎo)電性好，電阻系數(shù)極低或近乎零。3）、對焊接金屬表面要求低，氧化或電鍍均可焊接。4）、焊接時間短，不需任何助焊劑、氣體、焊料。5）、焊接無火花，環(huán)保安全。適用產(chǎn)品：1）、鎳氫電池鎳氫電池鎳網(wǎng)與鎳片互熔與鎳片互熔。2）、鋰電池、聚合物電池銅箔與鎳片互熔，鋁箔與鋁片互熔。3）、電線互熔，偏結(jié)成一條與多條互熔。4）、電線與各種電子元件、接點(diǎn)、連接器互熔。5）、各種家電用品、汽車用品的大型散熱座、熱交換鰭片、蜂巢心的互熔。6）、電磁開關(guān)、無熔絲開關(guān)等大電流接點(diǎn)，異種金屬片的互熔。7）、金屬管的封尾、切斷防水、氣密。超聲波焊接已在世界各地的熱封和塑料焊接應(yīng)用中找到了用途。</p><div
