一、取斷絲錐機工作原理
以前常(chang)規處理(li)絲錐、鉆頭(tou)等折(zhe)斷在工具里的方法(fa)無非是手工慢慢剔(ti)、砸碎、氣焊后擰出,甚(shen)至酸腐蝕、火(huo)焰切割(ge)燒等方法(fa),不但很多時(shi)候處理(li)不好,即(ji)使處理(li)完,也(ye)會損傷工件。因此有了(le)電火(huo)花取斷絲錐,很好的解決了(le)這(zhe)些問(wen)題。
電火花取斷絲錐是(shi)一(yi)種利用脈沖放電(dian)的方式,對各種鋼(gang)、鐵及硬質合金等,進(jin)行高效加工的電(dian)火花設備。
通過電(dian)(dian)(dian)火花取斷(duan)絲錐(zhui)在工(gong)(gong)(gong)具電(dian)(dian)(dian)極(ji)和工(gong)(gong)(gong)件(jian)(jian)之間(jian)(jian)施加脈沖電(dian)(dian)(dian)壓(達到(dao)間(jian)(jian)隙中(zhong)(zhong)介(jie)質的(de)(de)(de)(de)擊(ji)穿(chuan)電(dian)(dian)(dian)壓)時(shi),會擊(ji)穿(chuan)介(jie)質,由于放電(dian)(dian)(dian)區(qu)(qu)域很小,放電(dian)(dian)(dian)時(shi)間(jian)(jian)極(ji)短,所以(yi),能(neng)量高度集(ji)中(zhong)(zhong),使放電(dian)(dian)(dian)區(qu)(qu)的(de)(de)(de)(de)溫度瞬時(shi)高達10000-12000℃,工(gong)(gong)(gong)件(jian)(jian)表(biao)(biao)(biao)面(mian)和工(gong)(gong)(gong)具電(dian)(dian)(dian)極(ji)表(biao)(biao)(biao)面(mian)的(de)(de)(de)(de)金屬(shu)局部(bu)熔化、甚至汽化蒸發。局部(bu)熔化和汽化的(de)(de)(de)(de)金屬(shu)在爆炸力(li)(li)與震動(dong)力(li)(li)的(de)(de)(de)(de)雙重(zhong)作用下(xia)(xia)拋(pao)入(ru)工(gong)(gong)(gong)作液中(zhong)(zhong),從而使工(gong)(gong)(gong)件(jian)(jian)表(biao)(biao)(biao)面(mian)形(xing)成一個微小的(de)(de)(de)(de)凹坑(keng)。每次(ci)放電(dian)(dian)(dian)后,介(jie)質的(de)(de)(de)(de)絕緣強(qiang)度自動(dong)恢復(fu),等待下(xia)(xia)一次(ci)的(de)(de)(de)(de)被擊(ji)穿(chuan)放電(dian)(dian)(dian)。如此反復(fu)使工(gong)(gong)(gong)件(jian)(jian)表(biao)(biao)(biao)面(mian)不(bu)斷(duan)被蝕除,并在工(gong)(gong)(gong)件(jian)(jian)上復(fu)制出工(gong)(gong)(gong)具電(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)形(xing)狀,從而達到(dao)成型(xing)加工(gong)(gong)(gong)的(de)(de)(de)(de)目的(de)(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、帶有折斷絲錐或鉆頭等硬(ying)質合(he)金(jin)物的(de)工件一(yi)個、工作夜(水或者煤油)、?8水管(guan)一(yi)根(稍長(chang)一(yi)點)。準(zhun)備好(hao)工具后,可以按照以下步驟進行(xing):
1、將取斷絲錐機(ji)(ji)機(ji)(ji)頭(tou)與主機(ji)(ji)連接并鎖緊(jin)。
2、將工(gong)件(jian)固(gu)定(如果工(gong)件(jian)比(bi)較(jiao)小,可(ke)以(yi)將工(gong)件(jian)放在(zai)(zai)注入適當水的(de)(de)盆中,以(yi)水完全(quan)蓋住工(gong)件(jian)為宜;如果比(bi)較(jiao)大,且在(zai)(zai)一個穩固(gu)的(de)(de)位置(zhi),可(ke)以(yi)將機(ji)頭(tou)(tou)吸附(fu)在(zai)(zai)工(gong)件(jian)上(shang)),將準備好(hao)的(de)(de)電極安裝在(zai)(zai)機(ji)頭(tou)(tou)夾鉗中固(gu)定好(hao),然(ran)后將電極對準待加工(gong)位置(zhi)。松動機(ji)頭(tou)(tou)后面花螺母(mu),上(shang)下調整機(ji)頭(tou)(tou)行程(cheng),以(yi)達(da)到(dao)最(zui)合適加工(gong)位置(zhi)(電極距離折(zhe)斷(duan)物稍有點(dian)距離即可(ke),為的(de)(de)是不(bu)讓設備一啟動,電極就打在(zai)(zai)折(zhe)斷(duan)物上(shang))。
3、將主(zhu)機(ji)與220V電源連(lian)接(jie),并啟動(dong)主(zhu)機(ji)后面(mian)板上(shang)的開(kai)關按鈕,在主(zhu)機(ji)前面(mian)板上(shang)啟動(dong)電磁吸(xi)(xi)盤(如果工件較小,機(ji)頭放在地面(mian)上(shang)則(ze)不需要(yao)啟動(dong),反之(zhi)則(ze)必須要(yao)啟動(dong))吸(xi)(xi)盤啟動(dong),指示(shi)燈會亮起。
4、依(yi)次開啟主機(ji)面板上(shang)的工作(zuo)按(an)鈕(niu)、運作(zuo)按(an)鈕(niu)、進程按(an)鈕(niu),此時(shi)設(she)備開始工作(zuo)。取(qu)斷(duan)(duan)絲(si)(si)錐機(ji)取(qu)出(chu)斷(duan)(duan)絲(si)(si)錐的速度較(jiao)快,一分鐘取(qu)出(chu)一毫(hao)米。取(qu)出(chu)后(hou)關閉(bi)可以從(cong)后(hou)往前(qian)依(yi)次按(an)下(xia)去。
