对于线(xian)切(qie)(qie)(qie)割(ge)(ge)工(gong)(gong)(gong)件(jian)余(yu)(yu)留(liu)部(bu)位(wei)(wei)切(qie)(qie)(qie)割(ge)(ge)的(de)多次(ci)加工(gong)(gong)(gong),首先必(bi)须解决(jue)被加工(gong)(gong)(gong)工(gong)(gong)(gong)件(jian)的(de)导(dao)电(dian)(dian)问题,因为(wei)在高(gao)精(jing)度线(xian)切(qie)(qie)(qie)割(ge)(ge)加工(gong)(gong)(gong)中(zhong),线(xian)电(dian)(dian)极的(de)行(xing)走路(lu)(lu)线(xian)可能(neng)需要沿加工(gong)(gong)(gong)轨迹往复行(xing)走多次(ci),才能(neng)保(bao)(bao)证被加工(gong)(gong)(gong)工(gong)(gong)(gong)件(jian)具有(you)较高(gao)表面(mian)粗糙度和表面(mian)精(jing)度,这时线(xian)切(qie)(qie)(qie)割(ge)(ge)加工(gong)(gong)(gong)是靠工(gong)(gong)(gong)件(jian)余(yu)(yu)留(liu)部(bu)位(wei)(wei)起到导(dao)电(dian)(dian)作用以(yi)(yi)保(bao)(bao)障(zhang)电(dian)(dian)加工(gong)(gong)(gong)正常(chang)进行(xing)。但(dan)在进行(xing)工(gong)(gong)(gong)件(jian)余(yu)(yu)留(liu)部(bu)位(wei)(wei)的(de)切(qie)(qie)(qie)割(ge)(ge)加工(gong)(gong)(gong)时,若第一次(ci)切(qie)(qie)(qie)割(ge)(ge)即切(qie)(qie)(qie)下工(gong)(gong)(gong)件(jian)余(yu)(yu)留(liu)部(bu)位(wei)(wei),将会导(dao)致被切(qie)(qie)(qie)割(ge)(ge)部(bu)分(fen)与母(mu)(mu)体(ti)分(fen)离(li),以(yi)(yi)致导(dao)电(dian)(dian)回路(lu)(lu)中(zhong)断(duan),无法进行(xing)继续加工(gong)(gong)(gong),所(suo)以(yi)(yi)从线(xian)切(qie)(qie)(qie)割(ge)(ge)加工(gong)(gong)(gong)的(de)条件(jian)性(xing)(xing)和延续性(xing)(xing)考虑,必(bi)须使工(gong)(gong)(gong)件(jian)余(yu)(yu)留(liu)部(bu)位(wei)(wei)即便在多次(ci)切(qie)(qie)(qie)割(ge)(ge)的(de)情(qing)况下也能(neng)保(bao)(bao)持与母(mu)(mu)体(ti)之间正常(chang)导(dao)电(dian)(dian)的(de)要求。

为(wei)了实(shi)现(xian)上(shang)述目(mu)的,操作工人力图(tu)营造人为(wei)环境和(he)条件(jian)来(lai)满足导电(dian)要求,即(ji)当工作人员在(zai)(zai)操作电(dian)火花线切(qie)割(ge)(ge)机(ji)遇到(dao)切(qie)割(ge)(ge)工件(jian)余留部(bu)位(wei)时,可采用在(zai)(zai)被切(qie)割(ge)(ge)部(bu)分和(he)母(mu)体(ti)之(zhi)间粘(zhan)铜片(pian)和(he)在(zai)(zai)切(qie)割(ge)(ge)间隙中塞铜片(pian)的处理方(fang)法来(lai)造成(cheng)人为(wei)的定位(wei)条件(jian)和(he)导电(dian)条件(jian),使是火花加工得以继续进行(xing),其(qi)具体(ti)做法与技巧如下:

(1)在被切割部分(fen)与母体(ti)材(cai)料(liao)(liao)之间粘(zhan)贴连接铜片。其目的(de)(de)是使工(gong)件余留部分(fen)在切割时与母体(ti)材(cai)料(liao)(liao)相连固定(ding),保证线切割有良好(hao)的(de)(de)定(ding)位(wei)条件,从而保障工(gong)件有优(you)异(yi)的(de)(de)加工(gong)质量(liang),这可(ke)依照以下步骤进行:

①首先根据(ju)加(jia)(jia)工工件的大小把薄铜(tong)片(厚度(du)根据(ju)线电极(ji)情(qing)况和加(jia)(jia)工部位形状(zhuang)而(er)定)剪(jian)成(cheng)长条形,然后折叠,井保证(zheng)折叠部分一长一短。

②然后把铜(tong)片折叠的弯曲部分(fen)用小手锤(chui)锤(chui)平(ping),并用什锦锉修理(li)成楔(xie)形;

③再把经以上(shang)处理的(de)铜片塞到(dao)线电极加工(gong)所形(xing)成(cheng)的(de)缝隙(xi)里,同时在(zai)工(gong)件该(gai)部(bu)分的(de)表面滴上(shang)502胶水(即环氧树脂瞬时快干胶)。

由于切(qie)割(ge)时(shi),电(dian)火花线切(qie)割(ge)机冲水(shui)使工件(jian)所受(shou)压(ya)力(li)较大,若单纯用铜(tong)片塞(sai)紧(jin)来保证导电(dian)和固定(ding)(ding),容易产生以下(xia)问题(ti):(a)铜(tong)片塞(sai)得太松(song),担(dan)心固定(ding)(ding)不可靠(kao)、导电(dian)不稳定(ding)(ding);(b)铜(tong)片塞(sai)得太紧(jin),又担(dan)心损伤工件(jian)表面、破坏形位公差,所以采用502胶水(shui)来保证被(bei)切(qie)割(ge)部分(fen)与母体材(cai)料固定(ding)(ding);

④在将铜(tong)(tong)片塞(sai)进加(jia)(jia)工(gong)部位(wei)时(shi),应(ying)(ying)注(zhu)意是:用502胶(jiao)水(shui)粘贴(tie)连接铜(tong)(tong)片时(shi)应(ying)(ying)远离工(gong)件(jian)(jian)余(yu)留部件(jian)(jian)处,以(yi)免(mian)502胶(jiao)水(shui)渗到,造成绝缘。此(ci)外(wai)粘贴(tie)连接铜(tong)(tong)片的(de)位(wei)置应(ying)(ying)考虑(lv)对称分布,且应(ying)(ying)保(bao)证(zheng)(zheng)同时(shi)塞(sai)紧(jin),避免(mian)工(gong)件(jian)(jian)发生偏移,以(yi)致影响工(gong)件(jian)(jian)加(jia)(jia)工(gong)质(zhi)量。保(bao)证(zheng)(zheng)被(bei)切割工(gong)件(jian)(jian)余(yu)留部位(wei)形状的(de)正(zheng)确性和(he)精度的(de)可靠性。

(2)在被切割部(bu)分与母(mu)体材料之间填(tian)充导(dao)(dao)电铜(tong)(tong)片(pian)。把经折叠、剪(jian)齐、锤平和修锉的薄铜(tong)(tong)片(pian)填(tian)充在线电极(ji)加工(gong)(gong)形(xing)成的缝(feng)(feng)隙(xi)里,并(bing)(bing)使铜(tong)(tong)片(pian)和缝(feng)(feng)隙(xi)壁紧密贴(tie)合。填(tian)充此铜(tong)(tong)片(pian)的目的是(shi)(shi)(shi)为了导(dao)(dao)电,因为前面(mian)(mian)粘(zhan)贴(tie)连接铜(tong)(tong)片(pian)时(shi)(shi)用了502胶水,而502胶水是(shi)(shi)(shi)不(bu)导(dao)(dao)电的。为了实现导(dao)(dao)电要求,故采用填(tian)充导(dao)(dao)电铜(tong)(tong)片(pian)的方法,填(tian)充导(dao)(dao)电铜(tong)(tong)片(pian)时(shi)(shi)同样应(ying)(ying)注意铜(tong)(tong)片(pian)的对称布置(zhi)以(yi)及铜(tong)(tong)片(pian)应(ying)(ying)同时(shi)(shi)加紧,并(bing)(bing)且(qie)不(bu)能塞得过紧以(yi)免划伤工(gong)(gong)件(jian)的表(biao)面(mian)(mian)。不(bu)管(guan)是(shi)(shi)(shi)粘(zhan)贴(tie)连接铜(tong)(tong)片(pian)还(hai)是(shi)(shi)(shi)填(tian)充导(dao)(dao)电铜(tong)(tong)缝(feng)(feng)隙(xi)的形(xing)状。都应(ying)(ying)该把小铜(tong)(tong)片(pian)制成圆弧(hu)形(xing),而且(qie)还(hai)应(ying)(ying)该用金相(xiang)砂布打磨(mo)被锤过的铜(tong)(tong)片(pian)表(biao)面(mian)(mian),以(yi)保证铜(tong)(tong)片(pian)表(biao)面(mian)(mian)光(guang)滑以(yi)避免划伤工(gong)(gong)件(jian)已加工(gong)(gong)过的表(biao)面(mian)(mian)。

在采用(yong)电火(huo)花线(xian)切割(ge)(ge)机加工(gong)(gong)(gong)高硬度(du)(du)、高精度(du)(du)和(he)高复杂度(du)(du)的(de)(de)小型工(gong)(gong)(gong)件(jian)时,按照上述方(fang)法和(he)步骤(zhou)进行线(xian)切割(ge)(ge)加工(gong)(gong)(gong)中工(gong)(gong)(gong)件(jian)余(yu)留部位(wei)的(de)(de)精密切割(ge)(ge),是一种行之有效的(de)(de)方(fang)法,它(ta)所提出(chu)的(de)(de)步骤(zhou)和(he)技巧,经济(ji)简便、实用(yong)可行,从而为改善(shan)和(he)提高精密线(xian)切割(ge)(ge)加工(gong)(gong)(gong)的(de)(de)质(zhi)量和(he)效率探(tan)索(suo)出(chu)新的(de)(de)途(tu)径。
