style="text-indent:25px">超聲波焊接機(jī)按照自動(dòng)化水平可以分為自動(dòng)焊接機(jī)、半自動(dòng)超聲波焊接機(jī)、手動(dòng)焊接機(jī)，對(duì)于現(xiàn)代化企業(yè)來講，自動(dòng)化水平越高越有利于企業(yè)流水線生產(chǎn)，所以自動(dòng)焊接機(jī)的使用是企業(yè)未來的一個(gè)趨勢(shì)。焊接原理:超聲波塑膠焊接原理是由發(fā)生器產(chǎn)生20KHz(或15KHz)的高壓、高頻信號(hào)，通過換能系統(tǒng)，把信號(hào)轉(zhuǎn)換為高頻機(jī)械振動(dòng)，加于塑料制品工件上，通過工件表面及在分子間的磨擦而使傳遞到接口的溫度升高，當(dāng)溫度達(dá)到此工件本身的熔點(diǎn)時(shí)，使工件接口迅速熔化，繼而填充于接口間的空隙，當(dāng)震動(dòng)停止，工件同時(shí)在一定的壓力下冷卻定形，便達(dá)成高質(zhì)量的焊接。新型的15KHz超聲波塑膠焊接機(jī)，對(duì)焊接較軟的PE、PP材料，以及直徑超大，長(zhǎng)度超長(zhǎng)塑膠焊件，具有獨(dú)特的效果，能滿足各種產(chǎn)品的需要，能為用戶生產(chǎn)效率以及產(chǎn)品檔次貢獻(xiàn)。超聲波焊接設(shè)備由壓力機(jī)、超聲波發(fā)生器、超聲波換能器、超聲波變幅桿、超聲波焊頭和零件支撐工裝等組成。天津大型超聲波焊接設(shè)備生產(chǎn)廠家</p><p

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(gè)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(chǎng)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(gè)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(chǎng)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(chǎng)，使加工塑膠在上下電極間的高頻電場(chǎng)中，其內(nèi)部分子產(chǎn)生距力運(yùn)動(dòng)摩擦，在模具的壓力下得到其熔接目的，熔接效果。金屬超聲波焊接設(shè)備價(jià)格</p><p
