id="vyr3kwc" class="box"><p><p> 中頻點焊機日常維護要點： </p> <p> （1）使用前應當查看電力配線的接線部分，入力側、出力側等端子，佛山焊鋁點焊機，以及外部配線的接線部分，內部配線的接線部位的接線螺柱是否有松動現(xiàn)象，表面生銹時把把銹漬去除以使得導電良好。 </p> <p> （2）電極修磨損方面。質量的焊接點是需要高質量的電極來焊接成，電極是作用于工件的部分，有良好的導電性、硬度和較高的軟化溫度，但它仍不可避免的會在持續(xù)高壓沖擊和高溫下變形，定期使用銼刀對電極表面進行修磨或更換新電極。 </p> <p> （3）長期的使用難免會使外殼因碰接而變形，生銹而受損傷，內部零件也會消磨，因此在年度的保養(yǎng)和檢查時要實施不良品零件的更換和外殼修補及絕緣劣化部位的補強等綜合修補工作。不良品零件的更換在做保養(yǎng)時比較好能夠全部一次更換新品以確保焊機之性能，佛山焊鋁點焊機。 </p> <p> （4）冷卻方面。冷卻是為了降低焊接時產(chǎn)生的告高溫現(xiàn)象，所以要通過冷卻水來給電極，佛山焊鋁點焊機、次級回路、變壓器、可控硅、整流管等功率元件等進行降溫，保持設備不高溫，能正常使用。因此要經(jīng)常檢查各個分支水路是否通暢，及時疏通堵塞的水路。 </p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">點焊機系采用雙面雙點過流焊接的原理，工作時兩個電極加壓工件使兩層金屬在兩電極的壓力下形成一定的接觸電阻，而焊接電流從一電極流經(jīng)另一電極時在兩接觸電阻點形成瞬間的熱熔接，且焊接電流瞬間從另一電極沿兩工件流至此電極形成回路，并且不會傷及被焊工件的內部結構。點焊機按照用途分，有***式(通用式)、**式;按照同時焊接的焊點數(shù)目分，有單點式、雙點式、多點式;按照導電方式分，有單側的、雙側的;按照加壓機構的傳動方式分，有腳踏式、電動機-凸輪式、氣壓式、液壓式、復合式(氣液壓合式);按照運轉的特性分，有非自動化、自動化;按照安裝的方法分，有固定式，移動式或輕便式(懸掛式);按照焊機的活動電極(普通是上電極)的移動方向分，有垂直行程(電極作直線運動)、圓弧行程;按照電能的供給方式分，有工頻焊機(采用50赫茲交流電源)、脈沖焊機(直流脈沖焊機、儲能焊機等)、變頻焊機(如低頻焊機)。</p><div

style="text-indent:25px">點焊機工作原理：點焊的工藝過程為開通冷卻水;將焊件表面清理干凈，裝配準確后，送入上、下電極之間，施加壓力，使其接觸良好;通電使兩工件接觸表面受熱，局部熔化，形成熔核;斷電后保持壓力，使熔核在壓力下冷卻凝固　形成焊點;去除壓力，取出工件。焊接電流、電極壓力、通電時間及電極工作表面尺寸等點焊工藝參數(shù)對焊接質量有重大影響。點焊機利用正負兩極在瞬間短路時產(chǎn)生的高溫電弧來熔化電極間的被焊材料，來達到使它們結合的目的。點焊機的結構十分簡單，說白了就是一個大功率的變壓器，將220V交流電變?yōu)榈碗妷?，大電流的電源，可以是直流的也可以是交流的。電焊變壓器有自身的特點，就是具有電壓急劇下降的特性。在焊條引燃后電壓下降，電焊機的工作電壓的調節(jié)，除了一次的220/380電壓變換，二次線圈也有抽頭變換電壓，同時還有用鐵芯來調節(jié)的，可調鐵芯。電焊機一般是一個大功率的變壓器，系利用電感的原理做成的。電感量在接通和斷開時會產(chǎn)生巨大的電壓變化，利用正負兩極在瞬間短路時產(chǎn)生的高壓電弧來熔化電焊條上的焊料。來達到使它們結合的目的。</p></p><br
