Kunezisekelo eziningi zokukhetha izinto ze-graphite electrode, kodwa kunezinqubo ezine eziyinhloko:
1. Isilinganiso se-diameter yezinhlayiyana zezinto
Isilinganiso se-diameter yezinhlayiyana zento ethinta ngokuqondile isimo sokukhishwa kwento.
Uma kuncane usayizi wezinhlayiyana ezimaphakathi, kufana nokufana kokukhishwa kwempahla, ukukhishwa kuzinzile, kanye nekhwalithi ephezulu.
Ngokubumba nokubunjwa kwe-die-casting enezidingo eziphansi nezinembayo, ngokuvamile kuyanconywa ukusebenzisa izinhlayiya eziqinile, njenge-ISEM-3, njll.;ngesikhunta se-elekthronikhi esinezidingo eziphezulu kanye nokunemba, kunconywa ukusebenzisa izinto ezinosayizi wezinhlayiyana ophakathi kuka-4μm.
Ukuqinisekisa ukunemba nokuqedwa kwengaphezulu kwesikhunta esicutshunguliwe.
Uma kuncane usayizi wezinhlayiyana ezimaphakathi wento, kuncane ukulahleka kwento, namandla amakhulu phakathi kwamaqembu e-ion.
Isibonelo, i-ISEM-7 ivamise ukutuswa ngokunemba kwesikhunta sokufa nokubumba.Kodwa-ke, uma amakhasimende anezidingo zokunemba okuphezulu kakhulu, kuyanconywa ukuthi asebenzise izinto ze-TTK-50 noma ISO-63 ukuze kuqinisekiswe ukulahleka kwempahla okuncane.
Qinisekisa ukunemba kanye nobulukhuni bobuso besikhunta.
Ngesikhathi esifanayo, izinhlayiya ezinkulu, ijubane lokukhipha ngokushesha kanye nokulahlekelwa okuncane komshini onzima.
Isizathu esiyinhloko ukuthi ukuqina kwamanje kwenqubo yokukhishwa kuhlukile, okuholela ekuphumeni kwamandla okuhlukene.
Kodwa i-surface finish ngemva kokukhishwa nayo iyashintsha ngokushintsha kwezinhlayiya.
2. Amandla e-flexible wento
Amandla e-flexural wento ebonakalayo ukubonakaliswa okuqondile kwamandla wento, okubonisa ukucinana kwesakhiwo sangaphakathi sempahla.
Izinto ezisezingeni eliphakeme zinokusebenza okuhle kokumelana nokukhipha.Kuma-electrode anezidingo zokunemba okuphezulu, zama ukukhetha izinto ezingcono kakhulu zamandla.
Isibonelo: I-TTK-4 ingahlangabezana nezidingo zesikhunta esijwayelekile sesixhumi se-elekthronikhi, kodwa kwezinye izibunjwa zesixhumi se-elekthronikhi ezinezidingo zokunemba okukhethekile, ungasebenzisa usayizi wezinhlayiyana ofanayo kodwa into yamandla ephakeme kancane i-TTK-5.
3. Ukuqina kosebe lwempahla
Ekuqondeni okungaphansi kwe-graphite, i-graphite ngokuvamile ibhekwa njengento ethambile.
Kodwa-ke, idatha yangempela yokuhlola kanye nezimo zohlelo lokusebenza zibonisa ukuthi ubulukhuni be-graphite buphakeme kunabo bezinto zensimbi.
Embonini ye-graphite ekhethekile, indinganiso yokuhlola ubulukhuni bendawo yonke indlela yokulinganisa ubulukhuni be-Shore, futhi umgomo wayo wokuhlola uhlukile kuleso wezinsimbi.
Ngenxa yesakhiwo esinezingqimba zegraphite, inokusebenza okuhle kakhulu kokusika ngesikhathi sokusika.Amandla okusika acishe abe yi-1/3 kuphela yezinto zethusi, futhi indawo engaphezulu ngemuva komshini kulula ukuyiphatha.
Kodwa-ke, ngenxa yokuqina kwayo okuphezulu, ukugqoka kwamathuluzi ngesikhathi sokusika kuzoba kukhulu kakhulu kunamathuluzi okusika insimbi.
Ngesikhathi esifanayo, izinto ezinobunzima obuphezulu zinokulawula okungcono kokulahlekelwa kokukhishwa.
Kuhlelo lwethu lwezinto ezibonakalayo ze-EDM, kunezinto ezimbili ongakhetha kuzo ezintweni ezinosayizi wezinhlayiyana ezifanayo ezisetshenziswa kaningi, enye enobunzima obuphakeme kanti enye inobulukhuni obuphansi ukuze kuhlangatshezwane nezidingo zamakhasimende anezidingo ezahlukene.
isidingo.
Isibonelo: izinto ezinobukhulu obuyizinhlayiya obuyisilinganiso esingu-5μm zifaka i-ISO-63 ne-TTK-50;izinto zokwakha ngesilinganiso sosayizi wezinhlayiyana ze-4μm zifaka i-TTK-4 ne-TTK-5;izinto zokwakha ezinobukhulu bezinhlayiyana eziyi-2μm zifaka i-TTK-8 ne-TTK-9.
Ikakhulukazi kucatshangelwa okuthandwayo kwezinhlobo ezahlukene zamakhasimende zokukhishwa kukagesi kanye nomshini.
4. Ukumelana kwangaphakathi kwento
Ngokwezibalo zenkampani yethu ezicini zezinto zokwakha, uma izinhlayiya ezimaphakathi zezinto zifana, isivinini sokukhipha nge-resistivity ephakeme sizohamba kancane kune-resistivity ephansi.
Okwezinto zokwakha ezinosayizi ofanayo wezinhlayiyana ezimaphakathi, izinto zokwakha ezinokumelana okuphansi zizoba namandla aphansi nobulukhuni ngokulinganayo kunezinto ezinokumelana okuphezulu.
Okusho ukuthi, isivinini sokukhipha nokulahlekelwa kuzohluka.
Ngakho-ke, kubaluleke kakhulu ukukhetha izinto ngokuya ngezidingo zangempela zohlelo.
Ngenxa yemininingwane ye-powder metallurgy, ipharamitha ngayinye yeqoqo ngalinye lezinto ezinobubanzi obuthile bokuguquguquka kwevelu elimele.
Kodwa-ke, imiphumela yokukhishwa kwezinto ze-graphite zebanga elifanayo zifana kakhulu, futhi umehluko emiphumeleni yohlelo lokusebenza ngenxa yemingcele ehlukahlukene mncane kakhulu.
Ukukhethwa kwezinto ze-electrode kuhlobene ngokuqondile nomphumela wokukhishwa.Ngokwezinga elikhulu, ukuthi ukukhethwa kwezinto ezifanele kunquma isimo sokugcina sejubane lokukhipha, ukunemba komshini kanye nokuqina kwendawo.
Lezi zinhlobo ezine zedatha zimelela ukusebenza okuyinhloko kokukhishwa kwento futhi zinquma ngokuqondile ukusebenza kwento.
