一、取斷絲錐機工作原理
以前常規處(chu)(chu)理絲(si)錐(zhui)、鉆頭等折斷(duan)(duan)在(zai)工(gong)具里(li)的(de)方法無非是(shi)手工(gong)慢慢剔、砸碎、氣焊(han)后擰出,甚至酸腐蝕、火焰切割燒(shao)等方法,不但很多時候處(chu)(chu)理不好,即使處(chu)(chu)理完,也(ye)會損傷工(gong)件。因(yin)此(ci)有了電火花取斷(duan)(duan)絲(si)錐(zhui),很好的(de)解決了這些問(wen)題。
電火花取斷絲錐是一種利用脈(mo)沖放電的方式,對各種鋼、鐵及硬(ying)質(zhi)合金(jin)等(deng),進(jin)行高效加工的電火花設備。
通過電(dian)火花(hua)取斷(duan)絲錐在(zai)工(gong)(gong)(gong)(gong)具電(dian)極(ji)和工(gong)(gong)(gong)(gong)件之間施加脈沖電(dian)壓(達(da)到(dao)間隙中介(jie)(jie)質的(de)(de)(de)擊(ji)(ji)穿電(dian)壓)時(shi),會擊(ji)(ji)穿介(jie)(jie)質,由于放電(dian)區域很小,放電(dian)時(shi)間極(ji)短,所(suo)以(yi),能量高(gao)度集中,使(shi)(shi)(shi)放電(dian)區的(de)(de)(de)溫度瞬時(shi)高(gao)達(da)10000-12000℃,工(gong)(gong)(gong)(gong)件表(biao)面和工(gong)(gong)(gong)(gong)具電(dian)極(ji)表(biao)面的(de)(de)(de)金屬局(ju)部(bu)熔化、甚至汽(qi)化蒸發。局(ju)部(bu)熔化和汽(qi)化的(de)(de)(de)金屬在(zai)爆炸力與震動(dong)力的(de)(de)(de)雙重作(zuo)用(yong)下拋入工(gong)(gong)(gong)(gong)作(zuo)液中,從(cong)(cong)而使(shi)(shi)(shi)工(gong)(gong)(gong)(gong)件表(biao)面形成一個微(wei)小的(de)(de)(de)凹坑。每次放電(dian)后(hou),介(jie)(jie)質的(de)(de)(de)絕緣強(qiang)度自動(dong)恢復(fu),等待下一次的(de)(de)(de)被擊(ji)(ji)穿放電(dian)。如此反復(fu)使(shi)(shi)(shi)工(gong)(gong)(gong)(gong)件表(biao)面不斷(duan)被蝕(shi)除,并在(zai)工(gong)(gong)(gong)(gong)件上復(fu)制出工(gong)(gong)(gong)(gong)具電(dian)極(ji)的(de)(de)(de)形狀,從(cong)(cong)而達(da)到(dao)成型加工(gong)(gong)(gong)(gong)的(de)(de)(de)目(mu)的(de)(de)(de)。
二、取斷絲錐機的使用方法是什么
準備工具:220V電壓的電源、取斷絲錐機(包括主機、磁力吸盤的機頭、連接線、電源線)、電極一根、帶有折斷絲錐或鉆(zhan)頭等硬質合金物的工件一(yi)個、工作(zuo)夜(水(shui)或者煤(mei)油)、?8水(shui)管一(yi)根(gen)(稍長(chang)一(yi)點(dian))。準(zhun)備(bei)好工具(ju)后,可(ke)以按照以下(xia)步驟進行:
1、將取斷(duan)絲(si)錐(zhui)機機頭與主機連接并鎖緊(jin)。
2、將(jiang)工(gong)(gong)件(jian)固定(如果工(gong)(gong)件(jian)比較小,可以(yi)將(jiang)工(gong)(gong)件(jian)放在注入(ru)適(shi)當(dang)水的盆中,以(yi)水完全蓋住工(gong)(gong)件(jian)為(wei)宜;如果比較大,且(qie)在一個穩固的位置,可以(yi)將(jiang)機(ji)(ji)頭(tou)吸附在工(gong)(gong)件(jian)上),將(jiang)準備(bei)好的電(dian)極(ji)安裝在機(ji)(ji)頭(tou)夾鉗(qian)中固定好,然(ran)后將(jiang)電(dian)極(ji)對準待(dai)加(jia)工(gong)(gong)位置。松動機(ji)(ji)頭(tou)后面花(hua)螺母,上下調整機(ji)(ji)頭(tou)行程,以(yi)達到最合適(shi)加(jia)工(gong)(gong)位置(電(dian)極(ji)距(ju)離折(zhe)斷(duan)物稍有點距(ju)離即(ji)可,為(wei)的是(shi)不讓設備(bei)一啟(qi)動,電(dian)極(ji)就打在折(zhe)斷(duan)物上)。
3、將主(zhu)機(ji)(ji)與220V電(dian)源連接,并啟(qi)(qi)動(dong)(dong)(dong)主(zhu)機(ji)(ji)后面板上的開(kai)關按鈕(niu),在主(zhu)機(ji)(ji)前面板上啟(qi)(qi)動(dong)(dong)(dong)電(dian)磁(ci)吸(xi)盤(如(ru)果工件較小,機(ji)(ji)頭放在地面上則不需(xu)要啟(qi)(qi)動(dong)(dong)(dong),反(fan)之(zhi)則必(bi)須要啟(qi)(qi)動(dong)(dong)(dong))吸(xi)盤啟(qi)(qi)動(dong)(dong)(dong),指示燈會亮(liang)起。
4、依(yi)次(ci)開(kai)(kai)啟主機(ji)面(mian)板(ban)上的(de)工作按(an)(an)(an)鈕、運作按(an)(an)(an)鈕、進程按(an)(an)(an)鈕,此時設(she)備開(kai)(kai)始工作。取(qu)斷(duan)絲錐(zhui)機(ji)取(qu)出斷(duan)絲錐(zhui)的(de)速度較快,一分鐘取(qu)出一毫(hao)米。取(qu)出后(hou)關閉(bi)可以從后(hou)往前依(yi)次(ci)按(an)(an)(an)下去(qu)。
