Kune akawanda hwaro hwekusarudza graphite electrode zvinhu, asi pane mana makuru maitiro:
1. Avhareji yechidimbu dhayamita yezvinhu
Ivhareji yepakati dhayamita yezvinyorwa inokanganisa zvakananga mamiriro ekubuda kwezvinhu.
Iyo diki diki yeavhareji saizi yechinhu, iyo yakawanda yunifomu kubuda kwezvinhu, iyo yakanyanya kugadzikana yekubuda, uye zvirinani kunaka kwepamusoro.
Kugadzira uye kufa-kukanda mold ine yakaderera pasi uye chaiyo zvinodiwa, zvinowanzokurudzirwa kushandisa zvakakora zvimedu, senge ISEM-3, nezvimwewo;zvemagetsi molds ane yakakwirira pamusoro uye nemazvo zvinodiwa, zvinokurudzirwa kushandisa zvinhu ane avhareji particle size pazasi 4μm.
Kuti ive nechokwadi chekururama uye kupera kwepamusoro kweiyo yakagadzirwa mold.
Iyo diki yeavhareji saizi yechinhu, idiki kurasikirwa kwezvinhu, uye yakakura simba pakati pemapoka eion.
Semuyenzaniso, ISEM-7 inowanzokurudzirwa kuti inyatso kufa-kukanda molds uye kuforoma mold.Nekudaro, kana vatengi vaine yakanyanya kurongeka zvinodiwa, zvinokurudzirwa kushandisa TTK-50 kana ISO-63 zvinhu kuve nechokwadi chekurasikirwa kwezvinhu zvishoma.
Ita shuwa kurongeka uye kushata kwepamusoro kwe mold.
Panguva imwecheteyo, iyo yakakura iyo particles, inokurumidza kukurumidza kubuda uye kuduku kurasikirwa kwe rough machining.
Chikonzero chikuru ndechekuti ikozvino kusimba kwekuyerera kwakasiyana, izvo zvinoguma nekusiyana kwekubuda simba.
Asi iyo yepamusoro pekupedzisira mushure mekubuda zvakare inoshanduka nekuchinja kwezvikamu.
2. Flexural simba rezvinyorwa
Simba rekushanduka-shanduka kwechinhu chiratidziro chakananga chesimba rezvinhu, kuratidza kusimba kwemukati wemukati wezvinhu.
High-simba zvinhu zvine yakaringana discharge resistance performance.Kune ma electrode ane yakakwirira precision zvinodiwa, edza kusarudza zviri nani-simba zvinhu.
Semuenzaniso: TTK-4 inogona kusangana nezvinodiwa zveyakajairwa yemagetsi yekubatanidza molds, asi kune mamwe emagetsi ekubatanidza mold ane chakanyanya kudiwa zvinodiwa, unogona kushandisa saizi yakafanana asi yakakwirira zvishoma simba zvinhu TTK-5.
3. Shore kuoma kwezvinhu
Mukunzwisisa kusinganzwisisike kwegraphite, graphite inowanzoonekwa sechinhu chakapfava.
Nekudaro, data chaiyo yekuyedza uye mamiriro ekushandisa anoratidza kuti kuomarara kwegraphite kwakakwira kupfuura iyo yezvinhu zvesimbi.
Muindastiri yegraphite yakasarudzika, chiyero chekuomarara kwepasirese ndiyo nzira yekuyera kuoma kweShore, uye musimboti wayo wekuyedza wakasiyana neuyo wesimbi.
Nekuda kweiyo akaturikidzana chimiro chegraphite, ine yakanakisa yekucheka kuita panguva yekucheka maitiro.Simba rekucheka rinongoita 1/3 chete yemidziyo yemhangura, uye pamusoro mushure mekugadzira iri nyore kubata.
Zvisinei, nekuda kwekuoma kwayo kwepamusoro, chimbo chinopfeka panguva yekucheka chichave chakakura kudarika chesimbi yekucheka maturusi.
Panguva imwecheteyo, zvinhu zvine kuomarara kwakanyanya zvine kudzora kuri nani kwekurasikirwa kwekubuda.
Muchigadzirwa chedu che EDM, pane zvinhu zviviri zvokusarudza kubva kune zvigadzirwa zvehutatu humwechete hunoshandiswa kakawanda, imwe ine kuoma kwepamusoro uye imwe ine kuoma kwakaderera kuti isangane nezvinodiwa nevatengi vane zvinodiwa zvakasiyana.
kuda.
Semuyenzaniso: zvinhu zvine avhareji particle size ye5μm zvinosanganisira ISO-63 uye TTK-50;zvinhu zvine avhareji particle size ye4μm inosanganisira TTK-4 uye TTK-5;zvinhu zvine avhareji saizi ye2μm inosanganisira TTK-8 uye TTK-9.
Kunyanya kufunga nezvekuda kwemhando dzakasiyana dzevatengi kuburitsa magetsi uye machining.
4. The intrinsic resistivity yezvinhu
Zvinoenderana nenhamba dzekambani yedu pane hunhu hwezvinhu, kana maavhareji zvimedu zvezvinhu zvakafanana, iyo yekuburitsa kumhanya ine yakakwirira resistivity inononoka pane yakaderera resistivity.
Zvemidziyo ine avhareji saizi yechikamu, zvinhu zvine yakaderera resistivity zvichava neinoda kuderera simba uye kuoma pane zvinhu zvine yakakwira resistivity.
Ndiko kuti, kukurumidza kubuda uye kurasikirwa kuchasiyana.
Naizvozvo, zvakakosha zvikuru kusarudza zvinhu zvinoenderana nezvinodiwa chaizvo zvekushandisa.
Nekuda kwekusarudzika kwepoda metallurgy, imwe neimwe parameter yebatch yega yega yezvinhu ine kumwe kuchinjika kwehuwandu hwayo hwekumiririra kukosha.
Nekudaro, izvo zvinoburitsa mhedzisiro yegirafu zvinhu zvegiredhi rimwechete zvakafanana, uye mutsauko wekushandiswa kwemhedzisiro nekuda kweakasiyana ma paramita idiki kwazvo.
Kusarudzwa kwezvinhu zve electrode kunoenderana zvakananga nemhedzisiro yekubuda.Kusvika pamwero mukuru, kana kusarudzwa kwezvinhu kwakakodzera kunogadzirisa mamiriro ekupedzisira ekumhanya kwekubuda, machining akarurama uye pamusoro roughness.
Aya marudzi mana e data anomiririra kuburitsa kukuru kwekuita kwechinyorwa uye zvakanangana nekuita kwechinyorwa.
