Pali zifukwa zambiri zosankhira zipangizo za graphite electrode, koma pali mfundo zinayi zazikulu:
1. M'mimba mwake wa tinthu tating'onoting'ono ta zinthuzo
Kukula kwa tinthu tating'onoting'ono ta zinthuzo kumakhudza mwachindunji momwe zinthuzo zimatulutsidwira.
Kaya tinthu tating'onoting'ono ta chinthucho timakhala tating'onoting'ono, ndiye kuti kutulutsa kwa chinthucho kumakhala kofanana, kutulutsako kumakhala kokhazikika, komanso kumakhala bwino pamwamba pake.
Pakupanga ndi kuyika zinyalala zokhala ndi zofunikira zochepa pamwamba ndi kulondola, nthawi zambiri zimalimbikitsidwa kugwiritsa ntchito tinthu tating'onoting'ono, monga ISEM-3, ndi zina zotero; pa zinyalala zamagetsi zokhala ndi zofunikira zapamwamba pamwamba ndi kulondola, zimalimbikitsidwa kugwiritsa ntchito zipangizo zokhala ndi kukula kwa tinthu tating'onoting'ono tosakwana 4μm.
Kuonetsetsa kuti nkhungu yokonzedwayo ndi yolondola komanso yomaliza pamwamba pake.
Kaya tinthu tating'onoting'ono ta chinthucho timakhala tating'ono, ndiye kuti kutayika kwa chinthucho kumakhala kochepa, ndipo mphamvu pakati pa magulu a ayoni imakhala yayikulu.
Mwachitsanzo, ISEM-7 nthawi zambiri imalimbikitsidwa pa zinyalala zodulira molunjika komanso zodulira molunjika. Komabe, makasitomala akakhala ndi zofunikira kwambiri pakupanga zinthu molondola, amalimbikitsidwa kugwiritsa ntchito zipangizo za TTK-50 kapena ISO-63 kuti atsimikizire kuti zinthuzo sizitayika kwambiri.
Onetsetsani kuti nkhungu ndi yolondola komanso yolimba pamwamba pake.
Nthawi yomweyo, tinthu tating'onoting'ono tikakhala tambiri, liwiro lotulutsa limathamanga kwambiri ndipo kutayika kwa makina okhwima kumachepa.
Chifukwa chachikulu ndichakuti mphamvu zomwe zimagwiritsidwa ntchito potulutsa mpweya zimasiyana, zomwe zimapangitsa kuti pakhale mphamvu zosiyanasiyana zotulutsa mpweya.
Koma mawonekedwe a pamwamba pambuyo potulutsa madzi amasinthanso ndi kusintha kwa tinthu tating'onoting'ono.
2. Mphamvu yopindika ya zinthuzo
Mphamvu yopindika ya chinthu ndi chiwonetsero chachindunji cha mphamvu ya chinthucho, kusonyeza kulimba kwa kapangidwe ka mkati mwa chinthucho.
Zipangizo zolimba kwambiri zimakhala ndi mphamvu yolimbana ndi kutulutsa madzi bwino. Pa ma electrode omwe amafunikira kulondola kwambiri, yesani kusankha zipangizo zolimba kwambiri.
Mwachitsanzo: TTK-4 ikhoza kukwaniritsa zofunikira za zinyalala zamagetsi, koma pa zinyalala zamagetsi zina zomwe zili ndi zofunikira zapadera, mungagwiritse ntchito tinthu tating'onoting'ono tomwe tili ndi kukula kofanana koma mphamvu ya TTK-5 yokwera pang'ono.
3. Kulimba kwa gombe la zinthuzo
Mu kumvetsetsa kwa graphite, graphite nthawi zambiri imaonedwa ngati chinthu chofewa.
Komabe, deta yeniyeni yoyesera ndi momwe ntchito ikuyendera zikusonyeza kuti kuuma kwa graphite n'kokwera kuposa kwa zipangizo zachitsulo.
Mu makampani apadera a graphite, muyezo woyesera kuuma kwachilengedwe ndi njira yoyezera kuuma kwa Shore, ndipo mfundo yake yoyesera ndi yosiyana ndi ya zitsulo.
Chifukwa cha kapangidwe ka graphite, imakhala ndi magwiridwe antchito abwino kwambiri podula. Mphamvu yodulira ndi pafupifupi 1/3 yokha ya zinthu zamkuwa, ndipo pamwamba pake pakatha kupangidwa ndi kosavuta kugwiritsa ntchito.
Komabe, chifukwa cha kuuma kwake kwakukulu, kuwonongeka kwa chida podula kudzakhala kwakukulu pang'ono kuposa kwa zida zodulira zitsulo.
Nthawi yomweyo, zipangizo zolimba kwambiri zimakhala ndi mphamvu yowongolera bwino kutayika kwa zinthu zotuluka.
Mu dongosolo lathu la zinthu za EDM, pali zinthu ziwiri zomwe mungasankhe pazinthu zofanana ndi tinthu tating'onoting'ono zomwe zimagwiritsidwa ntchito mobwerezabwereza, chimodzi cholimba kwambiri ndi china cholimba pang'ono kuti chikwaniritse zosowa za makasitomala omwe ali ndi zofunikira zosiyanasiyana.
kufunikira.
Mwachitsanzo: zipangizo zomwe zili ndi kukula kwa tinthu tating'onoting'ono ta 5μm zikuphatikizapo ISO-63 ndi TTK-50; zipangizo zomwe zili ndi kukula kwa tinthu tating'onoting'ono ta 4μm zikuphatikizapo TTK-4 ndi TTK-5; zipangizo zomwe zili ndi kukula kwa tinthu tating'onoting'ono ta 2μm zikuphatikizapo TTK-8 ndi TTK-9.
Makamaka kuganizira zomwe makasitomala osiyanasiyana amakonda pa ntchito yotulutsa ndi kukonza magetsi.
4. Kukana kwamkati kwa zinthuzo
Malinga ndi ziwerengero za kampani yathu pa makhalidwe a zipangizo, ngati tinthu tambirimbiri ta zipangizozo ndi tofanana, liwiro lotulutsa zinthuzo ndi kukana kwakukulu lidzakhala locheperapo kuposa kukana kochepa.
Pa zipangizo zomwe zili ndi tinthu tating'onoting'ono tofanana, zipangizo zomwe zili ndi resistivity yochepa zidzakhala ndi mphamvu ndi kuuma kochepa poyerekeza ndi zipangizo zomwe zili ndi resistivity yapamwamba.
Ndiko kuti, liwiro lotulutsa ndi kutayika kwake zidzasiyana.
Choncho, ndikofunikira kwambiri kusankha zipangizo malinga ndi zosowa zenizeni zogwiritsira ntchito.
Chifukwa cha kudziwika kwa zitsulo za ufa, gawo lililonse la gulu lililonse la zinthu lili ndi kusinthasintha kwina kwa mtengo wake woyimira.
Komabe, zotsatira za kutulutsa kwa zinthu za graphite za mtundu womwewo ndizofanana kwambiri, ndipo kusiyana kwa zotsatira za kugwiritsidwa ntchito chifukwa cha magawo osiyanasiyana ndi kochepa kwambiri.
Kusankha zinthu za elekitirodi kumagwirizana mwachindunji ndi momwe zinthuzo zimakhudzira kutuluka kwa madzi. Kwambiri, ngati kusankha zinthuzo kuli koyenera kumatsimikizira momwe zinthuzo zimakhudzira kuthamanga kwa madzi, kulondola kwa makina ndi kukhwima kwa pamwamba.
Mitundu inayi ya deta iyi ikuyimira ntchito yayikulu yotulutsa zinthuzo ndipo imatsimikizira mwachindunji momwe zinthuzo zimagwirira ntchito.
