Zithini iingenelo kunye neengxaki zee-electrode ze-graphite xa kuthelekiswa nee-electrode zesinyithi zemveli?

Iingenelo

1. Isantya Sokwenziwa Kwemishini Esikhawulezayo
   Ii-electrode zegraphite zibonelela ngesantya sokugaya esikhutshwayo ngokukhawuleza ngokuphindwe kabini ukuya kathathu kunee-electrode zobhedu, ngakumbi xa kulungiswa ii-electrode ezi-thin-rib. Ngokumelana nokusika okumalunga ne-1/5 yobhedu, igraphite ivumela ukusebenza kakuhle kokugaya kwaye inciphisa kakhulu ixesha lokucubungula.

2. Ilula
   I-Graphite inobunzima obuyi-1/5 kuphela kunobobhedu, nto leyo enciphisa umthwalo kwizixhobo zoomatshini kwaye inciphisa ukuguguleka kwezixhobo, nto leyo eyenza ukuba ifaneleke ngakumbi kwiimold ezinkulu kunye nee-electrodes.

3. I-Coefficient yokwandisa ubushushu obuphantsi
   I-graphite's thermal expansion coefficient yi-1/30 kuphela yobhedu, iqinisekisa ukuguquguquka okuncinci ngexesha lokwenziwa kwe-machining kubushushu obuphezulu kwaye igcina ukuchaneka okuphezulu kokwenziwa kwe-machining, ngakumbi kwiimbambo ezinzulu, ezimxinwa kunye neendawo ezineendonga ezincinci.

4. Ukunxiba okuphantsi
   Ngexesha lokwenziwa kwe-discharge, ii-athomu zekhabhoni kulwelo lwe-dielectric ziyabola kumaqondo obushushu aphezulu kwaye zenze ifilimu ekhuselayo kumphezulu we-graphite electrode, nto leyo ehlawula ukuguguleka kwe-electrode. Ngokwahlukileyo koko, ii-electrode zobhedu zidla ngokuvelisa ii-burrs, ezifuna ukugqitywa okongezelelweyo ngesandla.

5. Akukho Burr kwaye kulula ukuyipolisha
   Ii-electrode zegrafiti azishiyi zi-burrs emva komatshini wokugaya, nto leyo esusa isidingo sokucubungula emva komatshini kwaye iququzelela imveliso ezenzekelayo. Ukongeza, ukumelana kwazo nokusika okuphantsi kwenza kube lula ukugaya nokupolisha.

6. Isebenza kakuhle emalini
   Ngenxa yokunyuka kwamaxabiso ethusi kwiminyaka yakutshanje, ii-electrode ze-graphite zihlala zizinzile ngokwexabiso. Ngaphezu koko, ii-electrode ze-graphite zitshiphu ngama-30%–60% kunee-electrode zethusi ezinomthamo ofanayo.

7. Ukusebenza kakuhle kobushushu obuphezulu
   Ii-electrode zegrafiti zinobushushu be-sublimation obufikelela kwi-3650°C, obudlula kakhulu inqanaba lokunyibilika kobhedu (1083°C), okuqinisekisa uzinzo kwiindawo ezinobushushu obuphezulu kunye nokufaneleka kwezicelo zoomatshini ezinamandla aphezulu, ezinombane ophezulu.

8. Igqwesileyo kwiMilo eNgcono yeMishini
   Ii-electrode zegrafiti zibunjwa lula zibe ziijometri ezintsonkothileyo, zihlangabezana neemfuno zeemolds ezichanekileyo kunye neendawo ezingafaniyo, ngelixa ii-electrode zekopolo zijongene nemingeni emikhulu ekubumbeni iimilo ezintsonkothileyo.

Iingxaki

1. Amandla Oomatshini Asezantsi
   Ii-electrode ze-graphite zinamandla aphantsi oomatshini, nto leyo eyenza ukuba zikwazi ukuqhekeka kwiikona ezibukhali, ingakumbi ngexesha lokwenziwa kwe-rough machining. Ukusika okuncinci okunezinga eliphezulu lokutya kuyafuneka ukuze kuthintelwe ukwaphuka kweekona okanye ukuqhekeka.

2. Ukuveliswa kothuli
   Ii-electrode ze-graphite ze-machining zivelisa uthuli olukhulu, nto leyo ebangela ukuba kufuneke iinkqubo ezikhethekileyo zokuvala kunye nokukhupha uthuli ukuze kukhuselwe izixhobo zoomatshini kunye nempilo yabaqhubi.

3. Ukusebenza kakubi kwi-Wire EDM
   Kwi-wire electrical discharge machining (Wire EDM), ii-graphite electrodes zibonisa isantya sokusika esimalunga ne-40% kancinci kunee-copper electrodes kwaye zinokwaphuka kwee-wire, nto leyo eyenza ukuba zingafaneleki ukusetyenziswa kwee-wire cutting ngokuchanekileyo.

4. Imida yoBurhabaxa bomphezulu
   Ukufikelela kumanqanaba oburhabaxa bomphezulu ngaphantsi kwe-VDI12 (Ra0.4μm) kunzima ngee-electrode ze-graphite. Kwi-machining yokukhupha i-discharge-finish, ii-electrode ze-copper zihlala ziyindlela ekhethwayo.

5. Ubunzima bokuRisayikilisha
   Iziqwenga ze-graphite electrode zinexabiso eliphantsi lokurisayikilisha kwaye kunzima ukuzisebenzisa kwakhona, nto leyo enyusa iindleko zokusetyenziswa kunye nefuthe kwindalo esingqongileyo.

6. Ubuqhophololo kunye nokungakhululeki kokwaphuka
   Ii-electrode zegrafiti zibuthathaka, ingakumbi ii-electrode ezibhityileyo okanye ezimxinwa, eziqhele ukuqhekeka phantsi kwamandla angaphandle, zifuna ukuphathwa ngononophelo.

7. Ayifanelekanga kwiMishini yokukhupha i-Fine Surface
   Kwimishini yokukhupha umphezulu ocolekileyo efuna ukugqitywa komphezulu ongaphantsi kwe-VDI12 (Ra0.4μm), ii-electrode zegrafiti azisebenzi kakuhle xa zithelekiswa nee-electrode zobhedu, nto leyo eyenza kube nzima ukuhlangabezana neemfuno zomphezulu ochanekileyo.
