線切割機床(chuang)高頻進(jin)電及(ji)變頻取(qu)樣通常有儲絲(si)筒進(jin)電方(fang)(fang)式、絲(si)架(jia)進(jin)電方(fang)(fang)式和擋絲(si)塊(kuai)進(jin)電方(fang)(fang)式。

 一(yi)、線切割儲絲筒進電方(fang)式

 儲(chu)絲筒(tong)(tong)進電(dian)(dian)(dian)是通過線切割機床儲(chu)絲筒(tong)(tong)中(zhong)心(xin)軸一端的石墨(mo)電(dian)(dian)(dian)刷(shua)(shua)實現的。脈沖電(dian)(dian)(dian)源負極(ji)與石墨(mo)電(dian)(dian)(dian)刷(shua)(shua)相(xiang)接(jie)，由彈簧保證石墨(mo)電(dian)(dian)(dian)刷(shua)(shua)與軸端緊密接(jie)觸，且(qie)中(zhong)心(xin)軸可旋轉，使石墨(mo)電(dian)(dian)(dian)刷(shua)(shua)磨損后，兩者仍能(neng)良好接(jie)觸。

 二、線切(qie)割機床絲架進電方式

 線(xian)切割絲架進(jin)電(dian)(dian)一般有導(dao)(dao)輪直接進(jin)電(dian)(dian)和(he)導(dao)(dao)電(dian)(dian)柱(zhu)進(jin)電(dian)(dian)兩種形式。

（1）導(dao)(dao)輪(lun)直接進電方(fang)式。此方(fang)法有利于(yu)減少(shao)(shao)線切(qie)割(ge)機床脈沖電源的(de)能量損耗，并減少(shao)(shao)外界(jie)干擾。為(wei)減少(shao)(shao)線切(qie)割(ge)導(dao)(dao)輪(lun)軸與進電部位的(de)摩擦力矩，可(ke)采用(yong)導(dao)(dao)電壺(hu)結(jie)構。線切(qie)割(ge)導(dao)(dao)針可(ke)采用(yong)不銹(xiu)鋼制造(zao)，而壺(hu)采用(yong)有機玻璃材料。

（2）線(xian)切(qie)(qie)割(ge)導(dao)電(dian)柱進(jin)電(dian)方(fang)式。此種進(jin)電(dian)方(fang)式的(de)導(dao)電(dian)柱一般用硬質合金制成(cheng)，固定在線(xian)切(qie)(qie)割(ge)絲(si)架的(de)上、下臂(bei)處靠近線(xian)切(qie)(qie)割(ge)導(dao)輪的(de)部位，通過其與電(dian)極(ji)絲(si)的(de)接觸進(jin)電(dian)由于放(fang)電(dian)腐蝕(shi)，線(xian)切(qie)(qie)割(ge)導(dao)電(dian)柱產生溝槽，因此應該不(bu)斷(duan)適當調整導(dao)電(dian)柱與電(dian)極(ji)絲(si)的(de)接觸位置，避免卡斷(duan)線(xian)切(qie)(qie)割(ge)機床(chuang)電(dian)極(ji)絲(si)。
