一、取斷絲錐機工作原理

以前常規(gui)處理絲(si)錐、鉆頭等(deng)折斷在工具(ju)里的方(fang)(fang)法無(wu)非(fei)是手工慢慢剔、砸碎、氣焊后擰出，甚至酸腐蝕、火焰切割燒等(deng)方(fang)(fang)法，不(bu)但很(hen)多時候處理不(bu)好(hao)，即(ji)使處理完，也(ye)會(hui)損傷工件(jian)。因此有了電火花取斷絲(si)錐，很(hen)好(hao)的解決了這(zhe)些問(wen)題。

電火花取斷絲錐是(shi)一種利(li)用脈沖放(fang)電的方(fang)式，對各種鋼、鐵及硬質(zhi)合金等，進行(xing)高效加(jia)工的電火(huo)花設備。

通過(guo)電(dian)(dian)(dian)(dian)火花(hua)取(qu)斷(duan)絲錐在(zai)工(gong)(gong)(gong)具電(dian)(dian)(dian)(dian)極和(he)(he)工(gong)(gong)(gong)件(jian)(jian)之間(jian)施加脈沖電(dian)(dian)(dian)(dian)壓(ya)(ya)（達到間(jian)隙中(zhong)介質的擊穿(chuan)(chuan)電(dian)(dian)(dian)(dian)壓(ya)(ya)）時(shi)，會擊穿(chuan)(chuan)介質，由于(yu)放電(dian)(dian)(dian)(dian)區(qu)域很(hen)小，放電(dian)(dian)(dian)(dian)時(shi)間(jian)極短，所以，能量高度(du)集中(zhong)，使放電(dian)(dian)(dian)(dian)區(qu)的溫度(du)瞬時(shi)高達10000-12000℃，工(gong)(gong)(gong)件(jian)(jian)表(biao)面(mian)和(he)(he)工(gong)(gong)(gong)具電(dian)(dian)(dian)(dian)極表(biao)面(mian)的金屬(shu)局部熔(rong)化、甚至汽化蒸發。局部熔(rong)化和(he)(he)汽化的金屬(shu)在(zai)爆(bao)炸力與(yu)震動力的雙重作用下拋(pao)入工(gong)(gong)(gong)作液中(zhong)，從而使工(gong)(gong)(gong)件(jian)(jian)表(biao)面(mian)形(xing)成一(yi)個微小的凹坑。每(mei)次(ci)放電(dian)(dian)(dian)(dian)后，介質的絕緣(yuan)強度(du)自動恢(hui)復，等待下一(yi)次(ci)的被擊穿(chuan)(chuan)放電(dian)(dian)(dian)(dian)。如此反復使工(gong)(gong)(gong)件(jian)(jian)表(biao)面(mian)不斷(duan)被蝕(shi)除，并在(zai)工(gong)(gong)(gong)件(jian)(jian)上復制出工(gong)(gong)(gong)具電(dian)(dian)(dian)(dian)極的形(xing)狀，從而達到成型加工(gong)(gong)(gong)的目的。

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(huo)鉆頭等硬質合(he)金物的工件一個、工作(zuo)夜（水或(huo)者(zhe)煤油(you)）、?8水管一根（稍長一點）。準備好工具后，可以按照以下步驟進(jin)行(xing)：

1、將取(qu)斷絲錐機機頭與主(zhu)機連接(jie)并鎖緊。

2、將工(gong)(gong)(gong)(gong)件(jian)(jian)固(gu)定（如果工(gong)(gong)(gong)(gong)件(jian)(jian)比較小，可以(yi)(yi)將工(gong)(gong)(gong)(gong)件(jian)(jian)放在注入(ru)適當水(shui)的盆中(zhong)，以(yi)(yi)水(shui)完全蓋住工(gong)(gong)(gong)(gong)件(jian)(jian)為宜；如果比較大，且(qie)在一個穩固(gu)的位置(zhi)，可以(yi)(yi)將機頭(tou)吸附在工(gong)(gong)(gong)(gong)件(jian)(jian)上），將準備(bei)好的電(dian)極(ji)安裝在機頭(tou)夾鉗中(zhong)固(gu)定好，然后將電(dian)極(ji)對準待加工(gong)(gong)(gong)(gong)位置(zhi)。松動(dong)機頭(tou)后面花螺母，上下調整機頭(tou)行程，以(yi)(yi)達到最合適加工(gong)(gong)(gong)(gong)位置(zhi)（電(dian)極(ji)距離折斷物稍有點距離即可，為的是不(bu)讓(rang)設備(bei)一啟(qi)動(dong)，電(dian)極(ji)就打在折斷物上）。

3、將主機與220V電(dian)源連接(jie)，并啟(qi)(qi)(qi)動(dong)主機后面板上的(de)開關(guan)按鈕，在主機前(qian)面板上啟(qi)(qi)(qi)動(dong)電(dian)磁吸盤（如果工件較(jiao)小，機頭放在地面上則不需要啟(qi)(qi)(qi)動(dong)，反(fan)之(zhi)則必須要啟(qi)(qi)(qi)動(dong)）吸盤啟(qi)(qi)(qi)動(dong)，指示燈(deng)會亮起。

4、依次(ci)開啟主機面板上的(de)工(gong)作(zuo)按鈕、運作(zuo)按鈕、進程按鈕，此(ci)時設備開始工(gong)作(zuo)。取(qu)斷(duan)絲(si)錐(zhui)機取(qu)出斷(duan)絲(si)錐(zhui)的(de)速度較(jiao)快，一(yi)分鐘取(qu)出一(yi)毫米(mi)。取(qu)出后(hou)關閉可以從后(hou)往前依次(ci)按下去。
