style="text-indent:25px">用戶在使用時可參考下列工藝數(shù)據(jù)：1、焊接時間：在焊接中低碳鋼時，本焊機(jī)可利用強(qiáng)規(guī)范焊接法(瞬時通電)或弱規(guī)范焊接法(長時通電)。在大量生產(chǎn)時應(yīng)采用強(qiáng)規(guī)范焊接法，它能提高生產(chǎn)效率，安徽鍍鋅板**點焊機(jī)，減少電能消耗及減輕工件變形。2、焊接電流：焊接電流決定于焊件之大小、厚度及接觸表面的情況，安徽鍍鋅板**點焊機(jī)。通常金屬導(dǎo)電率越高，電極壓力越大，焊接時間應(yīng)越短。此時所需的電流密度也隨之增大。3，安徽鍍鋅板**點焊機(jī)、電極壓力：電極對焊件施加壓力的目的是為了減小焊點處的接觸電阻，并保證焊點形成時所需要的壓力。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="安徽鍍鋅板**點焊機(jī)" src="http://tyunfile.71360.com/UpLoadFile/suzhouanjia/2020/1/637140711363933312/6371407113639333125663520.jpg"></div><p style="text-indent:25px">點焊機(jī)使用方法： 1、焊接時應(yīng)先調(diào)節(jié)電極桿的位置，使電極剛好壓到焊件時，電極臂保持互相平行。 2、電流調(diào)節(jié)開關(guān)級數(shù)的選擇可按焊件厚度與材質(zhì)而選定。通電后電源指示燈應(yīng)亮，電極壓力大小可調(diào)整彈簧壓力螺母，改變其壓縮程度而獲得。 3、在完成上述調(diào)整后，可先接通冷卻水后再接通電源準(zhǔn)備焊接。焊接過程的程序：焊件置于兩電極之間，踩下腳踏板，并使上電極與焊件接觸并加壓，在繼續(xù)壓下腳踏板時，電源觸頭開關(guān)接通，于是變壓器開始工作次級回路通電使焊件加熱。當(dāng)焊接一定時間后松開腳踏板時電極上升，借彈簧的拉力先切斷電源而后恢復(fù)原狀，單點焊接過程即告結(jié)束。 4、焊件準(zhǔn)備及裝配：鋼焊件焊前須***一切臟物、油污、氧化皮及鐵銹，對熱軋鋼，比較好把焊接處先經(jīng)過酸洗、噴砂或用砂輪***氧化皮。未經(jīng)清理的焊件雖能進(jìn)行點焊，但是嚴(yán)重地降低電極的使用壽命，同時降低點焊的生產(chǎn)效率和質(zhì)量。對于有薄鍍層的中低碳鋼可以直接施焊。</p><div

style="text-indent:25px">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(zhǔn)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(zhì)量有重大影響。點焊機(jī)利用正負(fù)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(dá)到使它們結(jié)合的目的。點焊機(jī)的結(jié)構(gòu)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)榈碗妷海箅娏鞯碾娫?，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。</p></p><br
