Eminyakeni yamuva, ngokusetshenziswa kakhulu kwesikhunta se-graphite, inani lonyaka lokusebenzisa isikhunta embonini yemishini liphindwe izikhathi ezi-5 yenani eliphelele lazo zonke izinhlobo zamathuluzi omshini, futhi ukulahlekelwa okukhulu kokushisa nakho kuphambene kakhulu namandla akhona. -izinqubomgomo zokulondoloza e-China.Ukusetshenziswa okukhulu kwesikhunta akukhulisi nje kuphela izindleko zamabhizinisi, kodwa futhi kuholela ekuvaleni umugqa wokukhiqiza njalo ngenxa yokushintshwa njalo kwesikhunta, ekugcineni kubangele ukulahlekelwa okukhulu kwezomnotho.
Ngokusho kocwaningo, ngenxa yentengo yezinto zokusetshenziswa kwesikhunta kanye namandla enyuka kakhulu nezinye izizathu, inzuzo yomkhiqizo wemboni yesikhunta yehla ngonyaka odlule;
Ukushintsha kwezinto kusetshenziswa njengesilinganiso esikhulu soguquko nentuthuko.Kuyaqondakala ukuthi izinkampani eziningi zethule izinto zokukhishwa kwe-graphite spark, ekukhiqizeni isikhunta kudlala indima ebaluleke kakhulu.Uma kuqhathaniswa nesikhunta sethusi sendabuko, impahla ye-graphite inezinzuzo eziphezulu. ukunemba kwe-machining kanye nomphumela omuhle wendawo, ikakhulukazi ekucubunguleni kwe-mold cavity ngokunemba, udonga oluyinkimbinkimbi, oluncane, izinto eziqinile eziphakeme kunenzuzo enkulu.Uma kuqhathaniswa nethusi, impahla ye-graphite inezinzuzo ezifana nokusetshenziswa okuncane, isivinini sokukhipha ngokushesha, isisindo esincane futhi esincane. i-thermal expansion coefficient, ngakho-ke i-electrode yethusi isiye yaba inkomba yezinto zokucubungula ukukhishwa.Ngokuphambene, izinto ze-graphite electrode zinezinzuzo eziyisithupha ezilandelayo:
1. Isivinini esisheshayo; Ukukhishwa kwegraphite kushesha izikhathi ezi-2-3 kunethusi, futhi impahla akulula ukuyikhubaza. Inezinzuzo ezisobala ekusebenzeni kwe-electrode emincane eqinisiwe. Indawo yokuthambisa yethusi icishe ibe ngama-degree angu-1000, futhi kulula ukonakala ngenxa yokushisa.
2. Isisindo esilula;Ukuminyana kwegraphite kuyi-1/5 kuphela yaleyo yethusi. Lapho i-electrode enkulu icutshungulwa ngokukhipha, umthwalo wethuluzi lomshini (EDM) ungancishiswa ngokuphumelelayo, ofaneleka kakhulu ukusetshenziswa kwesikhunta esikhulu.
3. Ukumoshakala okuncane;Njengoba uwoyela wenhlansi uqukethe ama-athomu angu-C, izinga lokushisa eliphakeme libangela ukuba ama-athomu angu-C akuwoyela wenhlansi abole lapho kucutshungulwa ukukhishwa, futhi kwakheka ifilimu evikelayo ebusweni be-graphite electrode, evala isikhala sokulahleka kwe-electrode yegraphite.
4. Awekho ama-burrs;Ngemva kokuthi i-electrode yethusi isicutshunguliwe, ama-burrs adinga ukususwa ngesandla. Kodwa-ke, akukho burrs ngemuva kokucutshungulwa kwe-graphite, okungagcini nje ngokulondoloza izindleko eziningi kanye nabasebenzi, kodwa futhi kwenza kube lula ukuqaphela ukukhiqizwa okuzenzakalelayo.
5. Ukupholisha kalula;Ngenxa yokuthi ukumelana nokusika kwegraphite kungu-1/5 kuphela wethusi, kulula ukugaya nokupholisha ngesandla.
Vi. Izindleko eziphansi;Ngenxa yokukhuphuka kwentengo yethusi eminyakeni yamuva, intengo yegraphite kuzo zonke izici iphansi kunaleyo yethusi.Ngaphansi kwevolumu efanayo ye-Oriental carbon's universality, intengo yemikhiqizo ye-graphite iphansi ngo-30% kuya ku-60% kune eyethusi, intengo izinzile uma kuqhathaniswa, futhi ukushintshashintsha kwentengo yesikhashana kuncane.Ngokongiwa kwamandla, ukuvikelwa kwemvelo kanye nokusebenza kahle kokucubungula kuba okugxilwe kakhulu embonini yokukhiqiza, izinto zokwakha ze-graphite electrode zizothatha indawo kagesi wethusi futhi zidlale indima ebalulekile. indima ku-EDM.Ngokufanayo, emncintiswaneni okhulayo okhulayo emakethe yesikhunta namuhla, ukusetshenziswa kobuchwepheshe bokucubungula okuthuthukisiwe ukuthuthukisa imikhiqizo yesikhunta sekhwalithi ephezulu kuyindlela engcono kakhulu yamabhizinisi ukunqoba imakethe kanye namakhasimende.
