Na'urorin lantarki masu ƙarfin gaske na graphite, ta hanyar maye gurbin na'urorin lantarki na jan ƙarfe da na'urorin lantarki na graphite don kera mold, suna rage yawan zagayowar kera mold sosai, suna haɓaka yawan aiki, da rage farashin kera mold. A cikin 'yan shekarun nan, tare da gabatar da ƙirar daidai da inganci (tare da ƙara gajerun zagayowar mold), buƙatun mutane don samar da mold suna ƙaruwa da ƙaruwa. Saboda iyakoki daban-daban na na'urorin lantarki na jan ƙarfe da kansu, Ya ƙara gaza biyan buƙatun ci gaban masana'antar mold. Graphite, a matsayin kayan lantarki na EDM, an yi amfani da shi sosai a masana'antar mold saboda fa'idodinsa kamar ƙarfin injina mai yawa, nauyi mai sauƙi, saurin samarwa, ƙarancin faɗaɗawa, ƙarancin asara da sauƙin sakawa. Babu makawa zai maye gurbin na'urorin lantarki na jan ƙarfe.
1. Halayen Kayan Graphite Electrode
Injin CNC yana da saurin sarrafawa da sauri, ƙarfin injina mai yawa da kuma sauƙin sakawa. Saurin sarrafa injunan graphite ya ninka na electrodes na jan ƙarfe sau 3 zuwa 5, kuma saurin sarrafa daidaici yana da ban mamaki musamman. Bugu da ƙari, ƙarfinsa yana da girma sosai. Ga electrodes masu tsayi sosai (50 zuwa 90mm) da kuma siriri mai yawa (0.2 zuwa 0.5mm), ba sa fuskantar lalacewa yayin sarrafawa. Bugu da ƙari, a lokuta da yawa, samfuran suna buƙatar samun kyakkyawan tasirin rubutu. Wannan yana buƙatar cewa lokacin yin electrodes, ya kamata a yi su a matsayin electrodes na maza masu haɗaka gwargwadon iko. Duk da haka, akwai ɓoyayyun kusurwoyi daban-daban yayin samar da electrodes na maza masu haɗaka. Saboda sauƙin yanke graphite, ana iya magance wannan matsalar cikin sauƙi kuma ana iya rage yawan electrodes sosai, wanda electrodes na jan ƙarfe ba za su iya cimmawa ba.
2. Saurin samar da EDM, ƙaramin faɗaɗa zafi da ƙarancin asara: Saboda ingantaccen wutar lantarki na graphite fiye da na jan ƙarfe, saurin fitar da shi ya fi na jan ƙarfe sauri, yana ninka na jan ƙarfe sau 3 zuwa 5. Bugu da ƙari, yana iya jure wa babban wutar lantarki yayin fitarwa, wanda ya fi amfani ga injin fitar da wutar lantarki mai ƙarfi. A halin yanzu, a ƙarƙashin wannan girman, nauyin graphite ya ninka na jan ƙarfe sau 1/5, wanda ke rage nauyin EDM sosai. Yana da fa'idodi masu yawa wajen ƙera manyan electrodes da na'urorin lantarki na maza. Zafin sublimation na graphite shine 4200℃, wanda ya ninka na jan ƙarfe sau 3 zuwa 4 (zafin sublimation na jan ƙarfe shine 1100℃). A yanayin zafi mai yawa, canza

Yana da ƙanƙanta sosai a siffarsa (1/3 zuwa 1/5 na jan ƙarfe a ƙarƙashin irin wannan yanayin lantarki) kuma baya laushi. Ana iya canja wurin kuzarin fitarwa zuwa wurin aiki yadda ya kamata kuma tare da ƙarancin amfani. Saboda ƙarfin graphite yana ƙaruwa a yanayin zafi mai yawa, yana iya rage asarar fitarwa yadda ya kamata (rashin graphite shine 1/4 na jan ƙarfe), yana tabbatar da ingancin sarrafawa.
3. Nauyi mai sauƙi da ƙarancin farashi: A cikin farashin samar da saitin molds, lokacin injin CNC, lokacin EDM, da lalacewar lantarki na electrode sune mafi yawan jimlar kuɗin, kuma duk waɗannan ana ƙayyade su ta hanyar kayan lantarki da kanta. Idan aka kwatanta da jan ƙarfe, saurin injin da saurin EDM na graphite duka sun ninka na jan ƙarfe sau 3 zuwa 5. A halin yanzu, fasalin ƙarancin lalacewa da samar da electrode graphite mai haɗawa na iya rage adadin electrodes, ta haka rage yawan amfani da kayan da lokacin injin na electrodes. Duk waɗannan na iya rage farashin samar da molds sosai.
2. Bukatu da Halayen Sarrafa Inji da Lantarki na Electrodes na Graphite
1. Samar da na'urorin lantarki: Samar da na'urorin lantarki na graphite na ƙwararru galibi yana amfani da kayan aikin injina masu sauri don sarrafawa. Ya kamata kayan aikin injin su sami kyakkyawan kwanciyar hankali, tare da motsi mai sassa uku iri ɗaya da kwanciyar hankali ba tare da girgiza ba. Bugu da ƙari, daidaiton juyawa na abubuwan da ke ciki kamar babban shaft shima ya kamata ya zama mai kyau gwargwadon iko. Hakanan ana iya sarrafa na'urar lantarki akan kayan aikin injin gabaɗaya, amma tsarin rubuta hanyar kayan aiki ya bambanta da na na'urorin lantarki na jan ƙarfe.
2. Na'urar sarrafa fitar da wutar lantarki ta EDM electrodes na graphite electrodes ne na carbon. Saboda graphite yana da kyakkyawan ikon sarrafa wutar lantarki, yana iya adana lokaci mai yawa a cikin injin fitar da wutar lantarki, wanda kuma shine ɗayan dalilan da yasa ake amfani da graphite a matsayin electrode.
3. Halayen Sarrafa Graphite Electrodes: Graphite na masana'antu yana da tauri da rauni, wanda ke haifar da lalacewa mai tsanani a kan kayan aiki yayin aikin CNC. Gabaɗaya, ana ba da shawarar amfani da kayan aiki da aka lulluɓe da ƙarfe mai tauri ko lu'u-lu'u. Lokacin da ake yin graphite mai tauri, ana iya sanya kayan aikin kai tsaye a kan da kuma kashe kayan aikin. Duk da haka, yayin aikin gamawa, don hana fashewa da fashewa, galibi ana amfani da kayan aiki mai sauƙi da hanyar wucewa cikin sauri.
Gabaɗaya dai, graphite ba kasafai yake karyewa ba idan zurfin yankewa ya ƙasa da 0.2mm, kuma ana iya samun ingantaccen ingancin saman bangon gefe. Kurar da aka samar yayin aikin injinan graphite na CNC tana da girma sosai kuma tana iya mamaye layin jagora, sukurori da madaurin kayan aikin injin, da sauransu. Wannan yana buƙatar cewa kayan aikin injin sarrafa graphite suna da na'urori masu dacewa don magance ƙurar graphite, kuma aikin hatimin kayan aikin injin ya kamata ya zama mai kyau saboda graphite yana da guba. Foda graphite abu ne da ke da matuƙar saurin amsawa ga halayen sinadarai. Juriyarsa tana canzawa a cikin yanayi daban-daban, ma'ana ƙimar juriyarsa ta bambanta. Duk da haka, akwai abu ɗaya da ya kasance mai dorewa: foda graphite yana ɗaya daga cikin kyawawan kayan da ba na ƙarfe ba. Muddin an ajiye foda graphite a cikin wani abu mai hana ruwa shiga ba tare da katsewa ba, kamar siririn zare, har yanzu zai kasance mai amfani da wutar lantarki. Amma menene ƙimar juriya? Babu wani adadi mai mahimmanci ga wannan ƙimar, saboda kyawun foda graphite ya bambanta, kuma ƙimar juriya na foda graphite da ake amfani da shi a cikin kayan aiki da muhalli daban-daban suma za su bambanta.
Ba za ka san cewa foda mai tsabta mai suna graphite yana da amfani mai yawa ba:
Gabaɗaya, roba tana hana ruwa shiga. Idan ana buƙatar wutar lantarki, ana buƙatar ƙara abubuwan da ke haifar da wutar lantarki. Foda ta Graphite tana da kyawawan halayen wutar lantarki da kuma shafawa mai laushi. Ana sarrafa Graphite zuwa foda ta Graphite, wadda ke da kyawawan halaye na shafawa da kuma mai da iskar lantarki. Mafi girman tsarkin foda ta Graphite, haka nan ingancinsa zai inganta. Yawancin masana'antun samfuran roba na musamman suna buƙatar roba mai da iskar lantarki. To, za a iya ƙara foda ta Graphite a cikin roba don gudanar da wutar lantarki? Amsar ita ce eh, amma akwai kuma tambaya: Menene rabon foda ta Graphite a cikin roba? Wasu kamfanoni suna amfani da rabon da bai wuce 30% ba, wanda ake amfani da shi ga samfuran roba masu jure lalacewa kamar tayoyin mota, da sauransu. Akwai kuma masana'antun roba na musamman waɗanda ke amfani da rabon 100%. Irin waɗannan samfuran ne kawai za su iya gudanar da wutar lantarki. Babban ƙa'idar wutar lantarki ita ce ba za a iya katse mai da iskar lantarki ba, kamar waya. Idan an katse shi a tsakiya, ba za a iya kunna wutar lantarki ba. Foda ta Graphite mai da iskar lantarki a cikin roba mai da iskar lantarki ita ce mai da iskar lantarki. Idan foda ta Graphite ta toshe ta hanyar roba mai da iskar lantarki, ba za ta sake gudanar da wutar lantarki ba. Saboda haka, idan rabon foda na graphite ya yi ƙasa sosai, tasirin watsawa zai yi ƙasa sosai.
Foda ta Graphite wani abu ne da ke da matuƙar saurin kamuwa da halayen sinadarai. Juriyarsa tana canzawa a wurare daban-daban, ma'ana ƙimar juriyarsa ta bambanta. Duk da haka, akwai abu ɗaya da ya kasance ba ya canzawa: foda mai tsabta mai ƙarfi yana ɗaya daga cikin kayan da ba na ƙarfe ba. Muddin an ajiye foda ta Graphite a cikin wani abu mai hana ruwa shiga ba tare da katsewa ba, kamar siririn zare, har yanzu zai kasance mai amfani da wutar lantarki. Amma menene ƙimar juriya? Babu wani adadi mai mahimmanci ga wannan ƙimar, saboda kyawun foda ta Graphite ya bambanta, kuma ƙimar juriya ta foda ta Graphite da ake amfani da ita a cikin kayayyaki da muhalli daban-daban suma za su bambanta.
