Mabhenefiti ema electrode e graphite
1: Kuwedzera kuoma kwechimiro chemold uye kusiyana-siyana kwekushandiswa kwechigadzirwa kwakaita kuti pave nezvinodiwa zvakanyanya zvekuti muchina we spark unyatsobuda. Zvakanakira ma graphite electrodes zviri nyore kugadzirisa, kukurumidza kubviswa kwemagetsi, uye kurasikirwa kwakaderera kwe graphite. Nokudaro, vamwe vatengi ve spark machine vanobva mumapoka vanosiya ma electrodes emhangura vochinja kuenda kuma graphite electrodes. Pamusoro pezvo, mamwe ma electrodes ane chimiro chakasarudzika haagone kugadzirwa nemhangura, asi graphite iri nyore kugadzira, uye ma electrodes emhangura anorema uye haana kukodzera kugadzirisa ma electrodes makuru. Izvi zvakaita kuti vamwe vatengi ve spark machine vanobva mumapoka vashandise ma electrodes e graphite.
2: Ma electrode eGraphite ari nyore kugadzirisa, uye kumhanya kwekugadzirisa kunokurumidza kupfuura ma electrode emhangura. Semuenzaniso, kushandisa tekinoroji yekugaya kugadzira graphite, kumhanya kwayo kwekugadzirisa kunokurumidza ka2-3 kupfuura mamwe ma electrode esimbi uye hakudi kuwedzerwa kugadziriswa nemaoko, nepo ma electrode emhangura achida kukuya nemaoko. Saizvozvowo, kana nzvimbo yekugadzira graphite inokurumidza kushandiswa kugadzira ma electrode, kumhanya kuchakurumidza uye kushanda zvakanaka kuchave kwakakwira, uye hapazovi nematambudziko eguruva. Mumaitiro aya, kusarudza maturusi ane kuoma kwakakodzera uye graphite kunogona kuderedza kupera kwemidziyo uye kukuvara kwemhangura. Kana ukaenzanisa nguva yekugaya yema electrode egraphite nema electrode emhangura, ma electrode egraphite anokurumidza ne67% kupfuura ma electrode emhangura. Mukushandiswa kwemagetsi ekuburitsa magetsi, kugadziriswa kwema electrode egraphite kunokurumidza ne58% kupfuura ma electrode emhangura. Nenzira iyi, nguva yekugadzira inoderedza zvikuru, uye mari yekugadzira inoderedzwawo.
3: Magadzirirwo e graphite electrode akasiyana nee electrode yemhangura yechinyakare. Mafekitori mazhinji e mold anowanzo kuve nemvumo dzakasiyana dzekugadzirisa nekupedzisa ma electrode emhangura, nepo ma electrode e graphite achishandisa mvumo dzakafanana. Izvi zvinoderedza huwandu hweCAD/CAM nekugadzirwa kwemuchina. Nekuda kwechikonzero ichi chete, Zvakakwana kuvandudza kururama kwe mold cavity zvakanyanya.
Ehe, mushure mekunge fekitori yemhando ye "mold" yachinja kubva kuma "copper electrodes" kuenda kuma "graphite electrodes", chinhu chekutanga chinofanira kujeka ndechekuti mashandisirwo e "graphite" anoitwa sei uye kufunga nezvezvimwe zvinhu zvine chekuita nazvo. Mazuva ano, vamwe vatengi vemuchina we "spark" unoshanda neboka vanoshandisa graphite kugadzira "electrode discharge machining", izvo zvinobvisa maitiro ekupukuta kwe "mold cavity" uye "chemical polishing", asi zvichiri kuwana magumo anotarisirwa pamusoro. Pasina kuwedzera nguva uye maitiro ekupukuta, hazvigoneke kuti electrode yemhando ye "copper" igadzire workpiece yakadaro. Pamusoro pezvo, graphite yakakamurwa kuita mamakisi akasiyana. Mhedzisiro yakanaka yekugadzirisa inogona kuwanikwa nekushandisa mamakisi akakodzera e "graphite" uye "electric spark discharge parameters" pasi pemashandisirwo chaiwo. Kana mushandi achishandisa ma "parameter" akafanana ne "copper electrode" pamuchina we "spark" uchishandisa ma "graphite electrodes", mhedzisiro yacho inofanira kunge isingafadzi. Kana uchida kudzora zvinhu zve "electrode" zvakasimba, unogona kuisa graphite electrode mumamiriro asina kurasikirwa (kurasikirwa pasi pe1%) panguva yekugadzira "rough", asi electrode yemhando ye "copper" haishandiswe.
Graphite ine hunhu hwepamusoro hunotevera husingakwanise kuenzaniswa nemhangura:
Kumhanya kwekugadzirisa: kugadzira michina yekukuya nekukurumidza kunokurumidza katatu kupfuura mhangura; kupedzisa kugadzira michina yekukuya nekukurumidza kunokurumidza kashanu kupfuura mhangura
Kugona kushanda zvakanaka, kunogona kuita kuti kuenzanisira kwakaoma kwejometri kuve kwakaoma
Huremu hwakareruka, huwandu hwemhangura hushoma pane 1/4, electrode iri nyore kubatanidza
inogona kuderedza huwandu hwemaerekitironi rimwe chete, nekuti anogona kuunganidzwa kuita electrode yakabatana
Kugadzikana kwakanaka kwekupisa, hapana shanduko uye hapana maburi ekugadzirisa
