对(dui)于线切(qie)割(ge)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)余留(liu)部(bu)(bu)位(wei)切(qie)割(ge)的多次加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong),首先(xian)必须解决(jue)被(bei)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)的导(dao)(dao)电(dian)问题,因为在(zai)高精度线切(qie)割(ge)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)中,线电(dian)极的行(xing)(xing)走路(lu)线可(ke)能(neng)需要沿加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)轨迹往复行(xing)(xing)走多次,才能(neng)保(bao)证(zheng)被(bei)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)具(ju)有较高表面粗糙(cao)度和(he)(he)表面精度,这时线切(qie)割(ge)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)是靠工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)余留(liu)部(bu)(bu)位(wei)起到导(dao)(dao)电(dian)作(zuo)用以(yi)保(bao)障电(dian)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)正(zheng)常进行(xing)(xing)。但在(zai)进行(xing)(xing)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)余留(liu)部(bu)(bu)位(wei)的切(qie)割(ge)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)时,若第一次切(qie)割(ge)即切(qie)下工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)余留(liu)部(bu)(bu)位(wei),将会(hui)导(dao)(dao)致被(bei)切(qie)割(ge)部(bu)(bu)分与母体(ti)分离(li),以(yi)致导(dao)(dao)电(dian)回路(lu)中断,无法进行(xing)(xing)继续加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong),所以(yi)从线切(qie)割(ge)加(jia)(jia)(jia)(jia)(jia)工(gong)(gong)(gong)(gong)(gong)的条(tiao)件(jian)(jian)(jian)(jian)性(xing)(xing)和(he)(he)延(yan)续性(xing)(xing)考虑,必须使工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)(jian)余留(liu)部(bu)(bu)位(wei)即便在(zai)多次切(qie)割(ge)的情况下也能(neng)保(bao)持与母体(ti)之间正(zheng)常导(dao)(dao)电(dian)的要求。

为(wei)了实(shi)现上述(shu)目的,操作工(gong)人(ren)(ren)力图营(ying)造人(ren)(ren)为(wei)环(huan)境和条件来满足导(dao)(dao)电(dian)(dian)要求,即当工(gong)作人(ren)(ren)员(yuan)在操作电(dian)(dian)火花线切割(ge)机遇到(dao)切割(ge)工(gong)件余(yu)留部位时(shi),可采用(yong)在被(bei)切割(ge)部分和母体(ti)之(zhi)间(jian)粘铜片和在切割(ge)间(jian)隙(xi)中塞(sai)铜片的处理方法来造成人(ren)(ren)为(wei)的定(ding)位条件和导(dao)(dao)电(dian)(dian)条件,使是(shi)火花加工(gong)得(de)以继续进(jin)行,其具体(ti)做法与技巧如(ru)下:

(1)在(zai)被切(qie)割(ge)(ge)部分与(yu)母体材料之间粘贴连接铜片。其目的是(shi)使工件余留部分在(zai)切(qie)割(ge)(ge)时与(yu)母体材料相连固定,保证线切(qie)割(ge)(ge)有良好的定位条件,从而保障(zhang)工件有优异的加(jia)工质量,这可(ke)依照以下步骤进行(xing):

①首(shou)先根(gen)(gen)据加工工件的(de)大小(xiao)把(ba)薄铜片(pian)(厚度根(gen)(gen)据线电(dian)极情况和加工部位(wei)形状而定)剪成长条形,然后折(zhe)叠,井保(bao)证(zheng)折(zhe)叠部分一长一短(duan)。

②然后把铜片折叠的弯曲部分用(yong)小手锤锤平,并(bing)用(yong)什锦锉(cuo)修理成楔形;

③再(zai)把经以上(shang)处理的(de)铜(tong)片塞到线电极(ji)加(jia)工(gong)所形成的(de)缝隙里,同时(shi)在工(gong)件该(gai)部分的(de)表面滴上(shang)502胶水(shui)(即环氧树脂瞬时(shi)快(kuai)干胶)。

由于切割时,电火(huo)花线切割机冲水使工(gong)件所(suo)受压力较大,若单(dan)纯用铜片塞紧来保(bao)(bao)证导电和固定(ding),容易产生以下(xia)问题(ti):(a)铜片塞得(de)太松,担心固定(ding)不可靠、导电不稳定(ding);(b)铜片塞得(de)太紧,又(you)担心损伤工(gong)件表面、破坏形位公差,所(suo)以采用502胶(jiao)水来保(bao)(bao)证被切割部分与(yu)母体材料固定(ding);

④在将(jiang)铜(tong)片塞进(jin)加工(gong)(gong)部位时,应注意是:用502胶水(shui)粘贴(tie)(tie)连接铜(tong)片时应远离工(gong)(gong)件余(yu)留(liu)部件处,以免502胶水(shui)渗到,造成绝缘(yuan)。此外(wai)粘贴(tie)(tie)连接铜(tong)片的位置应考虑对(dui)称分布,且(qie)应保证同(tong)时塞紧,避免工(gong)(gong)件发生偏移,以致影响工(gong)(gong)件加工(gong)(gong)质量。保证被切割工(gong)(gong)件余(yu)留(liu)部位形状(zhuang)的正确(que)性(xing)(xing)和精(jing)度(du)的可靠性(xing)(xing)。

(2)在被(bei)切割部分与母体材料之间填(tian)(tian)充(chong)导(dao)(dao)电铜(tong)(tong)片(pian)。把(ba)(ba)经(jing)折叠、剪(jian)齐、锤(chui)平和(he)修锉的(de)(de)薄铜(tong)(tong)片(pian)填(tian)(tian)充(chong)在线电极加(jia)工形成(cheng)的(de)(de)缝(feng)隙(xi)里,并(bing)(bing)使铜(tong)(tong)片(pian)和(he)缝(feng)隙(xi)壁紧密贴合。填(tian)(tian)充(chong)此铜(tong)(tong)片(pian)的(de)(de)目的(de)(de)是(shi)(shi)(shi)为(wei)了(le)(le)(le)导(dao)(dao)电,因(yin)为(wei)前面(mian)粘(zhan)贴连接铜(tong)(tong)片(pian)时(shi)用(yong)(yong)了(le)(le)(le)502胶水,而502胶水是(shi)(shi)(shi)不(bu)导(dao)(dao)电的(de)(de)。为(wei)了(le)(le)(le)实现导(dao)(dao)电要求,故采用(yong)(yong)填(tian)(tian)充(chong)导(dao)(dao)电铜(tong)(tong)片(pian)的(de)(de)方法,填(tian)(tian)充(chong)导(dao)(dao)电铜(tong)(tong)片(pian)时(shi)同样应(ying)注意(yi)铜(tong)(tong)片(pian)的(de)(de)对称布置以(yi)及(ji)铜(tong)(tong)片(pian)应(ying)同时(shi)加(jia)紧,并(bing)(bing)且(qie)不(bu)能塞得(de)过(guo)(guo)紧以(yi)免划伤(shang)工件的(de)(de)表(biao)面(mian)。不(bu)管(guan)是(shi)(shi)(shi)粘(zhan)贴连接铜(tong)(tong)片(pian)还是(shi)(shi)(shi)填(tian)(tian)充(chong)导(dao)(dao)电铜(tong)(tong)缝(feng)隙(xi)的(de)(de)形状(zhuang)。都应(ying)该(gai)把(ba)(ba)小铜(tong)(tong)片(pian)制(zhi)成(cheng)圆弧形,而且(qie)还应(ying)该(gai)用(yong)(yong)金相砂布打磨(mo)被(bei)锤(chui)过(guo)(guo)的(de)(de)铜(tong)(tong)片(pian)表(biao)面(mian),以(yi)保证(zheng)铜(tong)(tong)片(pian)表(biao)面(mian)光滑以(yi)避免划伤(shang)工件已加(jia)工过(guo)(guo)的(de)(de)表(biao)面(mian)。

在采(cai)用(yong)电(dian)火花线切割(ge)机加工(gong)(gong)高硬度(du)、高精(jing)度(du)和高复杂度(du)的小型工(gong)(gong)件时(shi),按(an)照上(shang)述方法(fa)和步骤进行线切割(ge)加工(gong)(gong)中工(gong)(gong)件余留部位的精(jing)密切割(ge),是一种行之(zhi)有效的方法(fa),它所提出的步骤和技巧,经(jing)济简便(bian)、实用(yong)可行,从(cong)而为改善和提高精(jing)密线切割(ge)加工(gong)(gong)的质量和效率(lv)探索出新的途径(jing)。
