Ama-electrode e-graphite anamandla aphezulu kakhulu, ngokufaka ama-electrode ethusi esikhundleni sama-electrode e-graphite okukhiqiza isikhunta, afinyeza kakhulu umjikelezo wokukhiqiza isikhunta, athuthukise umkhiqizo wabasebenzi, futhi anciphise izindleko zokukhiqiza isikhunta. Eminyakeni yamuva nje, ngokwethulwa kwesikhunta esinembile kanye nesikhunta esisebenza kahle kakhulu (ngemijikelezo yesikhunta emifushane kakhulu), izidingo zabantu zokukhiqiza isikhunta ziye zanda kakhulu. Ngenxa yemikhawulo ehlukahlukene yama-electrode ethusi ngokwawo, iye yehluleka kakhulu ukuhlangabezana nezidingo zokuthuthukiswa kwemboni yesikhunta. I-Graphite, njengezinto ze-electrode ze-EDM, isetshenziswe kabanzi embonini yesikhunta ngenxa yezinzuzo zayo ezifana nokusebenza kahle kakhulu, isisindo esincane, ukwakheka okusheshayo, izinga lokukhula eliphansi kakhulu, ukulahleka okuphansi kanye nokugqoka okulula. Akunakugwenywa ukuthi izothatha indawo yama-electrode ethusi.
1. Izici zezinto ze-Graphite Electrode
Umshini wokugaya we-CNC unesivinini sokucubungula esisheshayo, ukusebenza kahle kakhulu kanye nokubopha okulula. Isivinini sokucubungula semishini ye-graphite siphindwe kathathu kuya kahlanu kune-electrode yethusi, futhi isivinini sokucubungula ngokunemba sivelele kakhulu. Ngaphezu kwalokho, amandla ayo aphezulu kakhulu. Kuma-electrode aphezulu kakhulu (50 kuya ku-90mm) kanye nama-electrode amancane kakhulu (0.2 kuya ku-0.5mm), awathambekeli ekuguqukeni ngesikhathi sokucubungula. Ngaphezu kwalokho, ezimweni eziningi, imikhiqizo idinga ukuba nomphumela omuhle kakhulu wokuthungwa. Lokhu kudinga ukuthi lapho kwenziwa ama-electrode, kufanele enziwe njengama-electrode wesilisa ahlanganisiwe ngangokunokwenzeka. Kodwa-ke, kunezindawo ezahlukahlukene ezifihliwe zokucaca ekhoneni ngesikhathi sokukhiqizwa kwama-electrode wesilisa ahlanganisiwe. Ngenxa yesakhiwo sokusika kalula se-graphite, le nkinga ingaxazululwa kalula futhi inani lama-electrode lingancishiswa kakhulu, okungafinyelelwa ama-electrode ethusi.
2. Ukwakheka kwe-EDM okusheshayo, ukwanda okuncane kokushisa kanye nokulahlekelwa okuphansi: Ngenxa yokuqhuba kukagesi kwe-graphite okungcono kuneyethusi, izinga layo lokukhipha lishesha kunelethusi, liphindwe kathathu kuya kahlanu kunelethusi. Ngaphezu kwalokho, ingamelana nomsinga omkhulu ngesikhathi sokukhipha, okuzuzisa kakhulu ekusetshenzisweni kokukhipha ugesi okuqinile. Okwamanje, ngaphansi komthamo ofanayo, isisindo se-graphite siphindwe ka-1/5 kunesethusi, okunciphisa kakhulu umthwalo we-EDM. Inezinzuzo ezinkulu ekukhiqizeni ama-electrode amakhulu nama-electrode abesilisa ahlanganisiwe. Izinga lokushisa le-sublimation le-graphite lingu-4200℃, okuphindwe kathathu kuya kane kunelethusi (izinga lokushisa le-sublimation lethusi lingu-1100℃). Emazingeni okushisa aphezulu, shintsha
I-electrode ye-graphite enamandla aphezulu kakhulu
Incane kakhulu ngesimo sayo (1/3 kuya ku-1/5 yethusi ngaphansi kwezimo ezifanayo zikagesi) futhi ayithambi. Amandla okukhipha angadluliselwa endaweni yokusebenza kahle nangokusetshenziswa okuphansi. Ngenxa yokuthi amandla e-graphite ayanda ngempela emazingeni okushisa aphezulu, inganciphisa ngempumelelo ukulahlekelwa kokukhipha (ukulahleka kwe-graphite ku-1/4 kwalokho kwethusi), okuqinisekisa ikhwalithi yokucubungula.
3. Isisindo esincane kanye nezindleko eziphansi: Ezindleleni zokukhiqiza zesethi yezikhunta, isikhathi sokugaya se-CNC, isikhathi se-EDM, kanye nokuguguleka kwama-electrode kwama-electrode kubalwa iningi lezindleko eziphelele, futhi konke lokhu kunqunywa yizinto ze-electrode uqobo. Uma kuqhathaniswa nethusi, isivinini sokugaya kanye nesivinini se-EDM se-graphite kokubili kuphindwe kathathu kuya kahlanu kunesethusi. Okwamanje, isici sokuguga okuncane kanye nokukhiqizwa kwe-electrode ye-graphite ehlanganisiwe kunganciphisa inani lama-electrode, ngaleyo ndlela kuncishiswe ukusetshenziswa kwezinto kanye nesikhathi sokugaya sama-electrode. Konke lokhu kunganciphisa kakhulu izindleko zokukhiqiza zezikhunta.
2. Izidingo kanye nezici Zokucubungula Kwemishini Nogesi Kwama-Graphite Electrodes
1. Ukukhiqizwa kwama-electrode: Ukukhiqizwa kwama-electrode e-graphite ochwepheshe kusebenzisa kakhulu amathuluzi omshini asheshayo ukuze kucutshungulwe. Amathuluzi omshini kufanele abe nokuzinza okuhle, abe nokunyakaza okufanayo nokuzinzile kwama-axis amathathu ngaphandle kokudlidliza. Ngaphezu kwalokho, ukunemba kokujikeleza kwezingxenye ezifana nomgodi oyinhloko kufanele futhi kube kuhle ngangokunokwenzeka. I-electrode ingacutshungulwa nakumathuluzi omshini ajwayelekile, kodwa inqubo yokubhala indlela yamathuluzi ihlukile kweyama-electrode ethusi.
2. Ukushintshwa kokukhishwa kukagesi kwe-EDM Ama-electrode e-graphite angama-electrode e-carbon. Ngenxa yokuthi i-graphite inokuqhuba kahle kukagesi, ingonga isikhathi esiningi ekushitshweni kokukhishwa kukagesi, okungenye yezizathu ezenza i-graphite isetshenziswe njenge-electrode.
3. Izici Zokucubungula Ama-Electrode E-Graphite: I-graphite yezimboni iqinile futhi iyaphuka, okubangela ukuguguleka okukhulu kumathuluzi ngesikhathi sokugaya i-CNC. Ngokuvamile, kunconywa ukusebenzisa amathuluzi ambozwe nge-alloy eqinile noma idayimane. Lapho kwenziwa i-graphite yokugaya engaqinile, ithuluzi lingabekwa ngqo phezu nangaphandle kwento yokusebenza. Kodwa-ke, ngesikhathi sokugaya okuqediwe, ukuvimbela ukuqhekeka nokuqhekeka, ithuluzi elilula kanye nendlela yokuhamba ngokushesha kuvame ukusetshenziswa.
Ngokuvamile, i-graphite ayivami ukuphuka lapho ukujula kokusika kungaphansi kuka-0.2mm, futhi ikhwalithi engcono yobuso bodonga oluseceleni nayo ingatholakala. Uthuli olukhiqizwa ngesikhathi sokucubungula ama-electrode e-graphite nge-CNC lukhulu kakhulu futhi lungangena ezinqoleni zokuqondisa, izikulufo ze-lead kanye nezipindle zethuluzi lomshini, njll. Lokhu kudinga ukuthi ithuluzi lomshini wokucubungula i-graphite libe namadivayisi afanele okubhekana nothuli lwe-graphite, futhi ukusebenza kokuvala kwethuluzi lomshini kufanele kube kuhle ngoba i-graphite inobuthi. I-Graphite powder iyinto ezwela kakhulu ekuphenduleni kwamakhemikhali. Ukumelana kwayo kuyashintsha ezindaweni ezahlukene, okusho ukuthi inani layo lokumelana liyahlukahluka. Kodwa-ke, kukhona into eyodwa ehlala ingaguquki: i-graphite powder ingenye yezinto ezinhle kakhulu ezingezona ezensimbi eziqhubayo. Uma nje i-graphite powder igcinwa entweni yokuvikela ngaphandle kokuphazamiseka, njengentambo encane, izosasebenza ngogesi. Kodwa liyini inani lokumelana? Akukho sibalo esiqondile saleli nani futhi, ngoba ubuncane be-graphite powder buyahlukahluka, futhi inani lokumelana le-graphite powder elisetshenziswa ezintweni nasezindaweni ezahlukene nalo lizohluka.
Ungase ungazi ukuthi i-graphite powder ehlanzekile kakhulu nayo inokusetshenziswa okuqhubayo:
Ngokuvamile, irabha iyavikela. Uma kudingeka ugesi, kudingeka kufakwe izinto eziqhuba ugesi. Impuphu yegraphite inezakhiwo ezinhle kakhulu zokulawula ugesi kanye nokwehlisa ugesi. Igraphite icutshungulwa ibe yimpuphu yegraphite, enezakhiwo ezinhle kakhulu zokulawula ugesi kanye nokuhambisa ugesi. Uma inhlanzeko yempuphu yegraphite iphakeme, kulapho ukusebenza kwayo kokulawula ugesi kuba ngcono khona. Izimboni eziningi zemikhiqizo yerabha ekhethekile zidinga irabha eqhuba ugesi. Khona-ke, ingabe impuphu yegraphite ingafakwa erabhini ukuze iqhube ugesi? Impendulo inguyebo, kodwa kukhona nombuzo: Iyini ingxenye yempuphu yegraphite erabhini? Amanye amabhizinisi asebenzisa ingxenye engengaphezu kuka-30%, esetshenziswa emikhiqizweni yerabha engagugi njengamathayi emoto, njll. Kukhona nezimboni zerabha ezikhethekile ezisebenzisa ingxenye engu-100%. Imikhiqizo enjalo kuphela engavikela ugesi. Isimiso esiyisisekelo sokulawula ugesi ukuthi umqhubi akakwazi ukuphazanyiswa, njengocingo. Uma iphazamiseka phakathi, ngeke ifakelwe ugesi. Impuphu yegraphite eqhuba ugesi erabhini eqhuba ugesi yi-conductor Uma impuphu yegraphite ivinjiwe yirabha evikela ugesi, ngeke isaqhuba ugesi. Ngakho-ke, uma ingxenye yempuphu ye-graphite iphansi kakhulu, umphumela wokuqhuba kungenzeka ube mubi.
Impuphu ye-graphite iyinto ezwela kakhulu ekuphenduleni kwamakhemikhali. Ukumelana kwayo kuyashintsha ezindaweni ezahlukene, okusho ukuthi inani layo lokumelana liyahlukahluka. Kodwa-ke, kukhona into eyodwa ehlala ingaguquki: impuphu ye-graphite ehlanzekile kakhulu ingenye yezinto ezinhle kakhulu ezingezona ezensimbi eziqhuba ugesi. Uma nje impuphu ye-graphite igcinwa entweni yokuvikela ngaphandle kokuphazamiseka, njengentambo encane, izoqhubeka nokufakelwa ugesi. Kodwa liyini inani lokumelana? Akukho sibalo esiqondile saleli nani futhi, ngoba ubuncane bempuphu ye-graphite buyahlukahluka, futhi inani lokumelana lempuphu ye-graphite esetshenziswa ezintweni nasezindaweni ezahlukene nalo lizohluka.
