对于线切(qie)(qie)(qie)割(ge)(ge)工(gong)(gong)(gong)(gong)件(jian)(jian)余(yu)(yu)留部位(wei)切(qie)(qie)(qie)割(ge)(ge)的(de)(de)多(duo)次加(jia)工(gong)(gong)(gong)(gong),首先必须解决被加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)件(jian)(jian)的(de)(de)导(dao)(dao)电(dian)(dian)问题,因为(wei)在高(gao)精度线切(qie)(qie)(qie)割(ge)(ge)加(jia)工(gong)(gong)(gong)(gong)中(zhong),线电(dian)(dian)极的(de)(de)行(xing)走(zou)路线可能(neng)需要沿(yan)加(jia)工(gong)(gong)(gong)(gong)轨迹(ji)往复(fu)行(xing)走(zou)多(duo)次,才能(neng)保(bao)证被加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)件(jian)(jian)具有较(jiao)高(gao)表面(mian)粗糙度和(he)表面(mian)精度,这时线切(qie)(qie)(qie)割(ge)(ge)加(jia)工(gong)(gong)(gong)(gong)是靠工(gong)(gong)(gong)(gong)件(jian)(jian)余(yu)(yu)留部位(wei)起到(dao)导(dao)(dao)电(dian)(dian)作用(yong)以保(bao)障电(dian)(dian)加(jia)工(gong)(gong)(gong)(gong)正常进(jin)行(xing)。但在进(jin)行(xing)工(gong)(gong)(gong)(gong)件(jian)(jian)余(yu)(yu)留部位(wei)的(de)(de)切(qie)(qie)(qie)割(ge)(ge)加(jia)工(gong)(gong)(gong)(gong)时,若第一次切(qie)(qie)(qie)割(ge)(ge)即切(qie)(qie)(qie)下工(gong)(gong)(gong)(gong)件(jian)(jian)余(yu)(yu)留部位(wei),将会导(dao)(dao)致被切(qie)(qie)(qie)割(ge)(ge)部分与(yu)母(mu)体分离(li),以致导(dao)(dao)电(dian)(dian)回(hui)路中(zhong)断,无(wu)法进(jin)行(xing)继续(xu)加(jia)工(gong)(gong)(gong)(gong),所以从线切(qie)(qie)(qie)割(ge)(ge)加(jia)工(gong)(gong)(gong)(gong)的(de)(de)条件(jian)(jian)性和(he)延续(xu)性考虑,必须使工(gong)(gong)(gong)(gong)件(jian)(jian)余(yu)(yu)留部位(wei)即便在多(duo)次切(qie)(qie)(qie)割(ge)(ge)的(de)(de)情况下也能(neng)保(bao)持(chi)与(yu)母(mu)体之间正常导(dao)(dao)电(dian)(dian)的(de)(de)要求。

为了实现上述目(mu)的,操(cao)作(zuo)(zuo)(zuo)工(gong)(gong)人力图营造人为环境和(he)条件(jian)来满(man)足导电要求,即当工(gong)(gong)作(zuo)(zuo)(zuo)人员在(zai)操(cao)作(zuo)(zuo)(zuo)电火(huo)花(hua)线(xian)切(qie)割(ge)(ge)机遇到切(qie)割(ge)(ge)工(gong)(gong)件(jian)余留部位(wei)时,可采用在(zai)被切(qie)割(ge)(ge)部分和(he)母体之(zhi)间粘铜片和(he)在(zai)切(qie)割(ge)(ge)间隙中塞铜片的处(chu)理方(fang)法来造成(cheng)人为的定(ding)位(wei)条件(jian)和(he)导电条件(jian),使是火(huo)花(hua)加工(gong)(gong)得以继(ji)续进行,其具体做法与技巧如下(xia):

(1)在被切(qie)割部分与母(mu)体材料(liao)之间粘贴连接(jie)铜片。其目(mu)的(de)是使工(gong)件余留部分在切(qie)割时与母(mu)体材料(liao)相连固定(ding)(ding),保证线切(qie)割有(you)良好的(de)定(ding)(ding)位条件,从而(er)保障(zhang)工(gong)件有(you)优异的(de)加工(gong)质(zhi)量,这可依照(zhao)以下步骤进行:

①首先(xian)根(gen)据(ju)加工(gong)工(gong)件的(de)大小把薄铜片(厚度根(gen)据(ju)线电极情况和加工(gong)部(bu)位形状而定)剪成(cheng)长条形,然后(hou)折(zhe)叠,井保(bao)证折(zhe)叠部(bu)分一长一短(duan)。

②然(ran)后(hou)把铜片折(zhe)叠的(de)弯(wan)曲部(bu)分用(yong)小手锤(chui)锤(chui)平,并(bing)用(yong)什锦锉修理成楔形;

③再把经以上处理的铜(tong)片(pian)塞到线电极加(jia)工(gong)所形(xing)成的缝隙(xi)里,同时(shi)在工(gong)件该部(bu)分的表面滴上502胶水(即环(huan)氧树(shu)脂瞬时(shi)快干胶)。

由于切割(ge)时,电(dian)火花线切割(ge)机(ji)冲(chong)水使工(gong)件所(suo)受压力较大,若单纯用铜(tong)(tong)片塞紧来保证(zheng)导(dao)电(dian)和固定(ding),容易(yi)产(chan)生以(yi)下问题:(a)铜(tong)(tong)片塞得(de)(de)太(tai)松,担(dan)心固定(ding)不可(ke)靠(kao)、导(dao)电(dian)不稳定(ding);(b)铜(tong)(tong)片塞得(de)(de)太(tai)紧,又担(dan)心损伤工(gong)件表面、破(po)坏形(xing)位公差(cha),所(suo)以(yi)采用502胶水来保证(zheng)被切割(ge)部分与母(mu)体(ti)材料固定(ding);

④在将铜片(pian)(pian)塞进(jin)加工(gong)部位时(shi)(shi),应注(zhu)意是:用502胶水粘贴连(lian)接(jie)铜片(pian)(pian)时(shi)(shi)应远离工(gong)件(jian)余留部件(jian)处,以免502胶水渗到(dao),造成绝缘。此外粘贴连(lian)接(jie)铜片(pian)(pian)的位置应考虑(lv)对(dui)称分布,且应保证(zheng)同(tong)时(shi)(shi)塞紧(jin),避免工(gong)件(jian)发生偏移,以致影(ying)响工(gong)件(jian)加工(gong)质量。保证(zheng)被切割工(gong)件(jian)余留部位形状的正(zheng)确性和精度的可靠性。

(2)在(zai)被(bei)(bei)切割部(bu)分与母体材料之间填(tian)(tian)充(chong)(chong)导电(dian)铜(tong)片(pian)。把经折(zhe)叠、剪齐、锤平和(he)修锉的(de)(de)(de)(de)薄铜(tong)片(pian)填(tian)(tian)充(chong)(chong)在(zai)线电(dian)极加(jia)(jia)工(gong)形成的(de)(de)(de)(de)缝隙里,并使铜(tong)片(pian)和(he)缝隙壁(bi)紧(jin)密贴合。填(tian)(tian)充(chong)(chong)此铜(tong)片(pian)的(de)(de)(de)(de)目的(de)(de)(de)(de)是(shi)为(wei)了(le)导电(dian),因(yin)为(wei)前(qian)面粘贴连(lian)接铜(tong)片(pian)时用了(le)502胶水,而502胶水是(shi)不(bu)(bu)导电(dian)的(de)(de)(de)(de)。为(wei)了(le)实现导电(dian)要求,故采(cai)用填(tian)(tian)充(chong)(chong)导电(dian)铜(tong)片(pian)的(de)(de)(de)(de)方法,填(tian)(tian)充(chong)(chong)导电(dian)铜(tong)片(pian)时同(tong)样(yang)应(ying)注意铜(tong)片(pian)的(de)(de)(de)(de)对称布(bu)置以(yi)(yi)及铜(tong)片(pian)应(ying)同(tong)时加(jia)(jia)紧(jin),并且不(bu)(bu)能塞得过紧(jin)以(yi)(yi)免划伤工(gong)件(jian)的(de)(de)(de)(de)表面。不(bu)(bu)管(guan)是(shi)粘贴连(lian)接铜(tong)片(pian)还是(shi)填(tian)(tian)充(chong)(chong)导电(dian)铜(tong)缝隙的(de)(de)(de)(de)形状。都应(ying)该把小铜(tong)片(pian)制成圆(yuan)弧形,而且还应(ying)该用金(jin)相砂布(bu)打磨被(bei)(bei)锤过的(de)(de)(de)(de)铜(tong)片(pian)表面,以(yi)(yi)保证铜(tong)片(pian)表面光滑以(yi)(yi)避免划伤工(gong)件(jian)已(yi)加(jia)(jia)工(gong)过的(de)(de)(de)(de)表面。

在采(cai)用电火花(hua)线(xian)(xian)切(qie)割机(ji)加(jia)工(gong)(gong)(gong)高硬度(du)(du)(du)、高精(jing)度(du)(du)(du)和(he)(he)高复杂(za)度(du)(du)(du)的小型工(gong)(gong)(gong)件(jian)时,按(an)照(zhao)上(shang)述方法和(he)(he)步(bu)骤(zhou)进行(xing)线(xian)(xian)切(qie)割加(jia)工(gong)(gong)(gong)中工(gong)(gong)(gong)件(jian)余留部位的精(jing)密切(qie)割,是(shi)一种行(xing)之有(you)效(xiao)(xiao)的方法,它所提(ti)出的步(bu)骤(zhou)和(he)(he)技巧,经济(ji)简便(bian)、实用可(ke)行(xing),从而为改善和(he)(he)提(ti)高精(jing)密线(xian)(xian)切(qie)割加(jia)工(gong)(gong)(gong)的质量和(he)(he)效(xiao)(xiao)率探索出新(xin)的途径(jing)。
