Yiziphi izici ezinhle kakhulu ze-graphite electrode

I-1, i-CNC MachingIngling inejubane lokucubungula ngokushesha, ikhono eliphakeme lokusika, kanye nokulungiswa okulula

Ijubane lemishini ye-CNC le-graphite lishesha, izikhathi 4-5 ezinge-electrodes zethusi. Ijubane lemishini elinembile livelele ikakhulukazi, namandla alo aphezulu kakhulu. Ku-Ultra-High (40-100mm) kanye ne-graphite electrodes (0.2-0.8mm) ama-electrodes we-graphite, awawonakali kalula ngesikhathi sokucutshungulwa. Ngaphezu kwalokho, ezimweni eziningi, imikhiqizo idinga ukuba nomphumela omuhle obhaliwe, odinga ukuthi uma wenza ama-electrode, kuyadingeka ukubenza babe ngama-electrodes ahlanganisiwe we-graphite ngangokunokwenzeka. Kodwa-ke, kunamakhona ahlukahlukene afihliwe ekukhiqizweni kwama-electrodes ahlanganisiwe we-graphite. Ngenxa yokulula ukunqamula imvelo ye-graphite, le nkinga ixazululwa kalula futhi inani le-electrodes lincishiswe kakhulu, yimaphi ama-electrodes ethusi angakwazi ukufeza.

2, hhayi kuphela ukuthi kungasindi, kepha futhi kunendleko ephansi

Ngezindleko zokukhiqiza zeqoqo lezikhunta, isikhathi semishini ye-CNC, isikhathi se-EDM, isikhathi sokulahleka kwe-electrode, njll. I-akhawunti ye-graphite ye-electrodes yobuningi bezindleko eziphelele, futhi konke konke kunqunywa yi-electrode ngokwayo.QhathanisaUkuze ithusi, ama-electrodes we-graphite anesivinini semishini kanye nesivinini se-EDM esinezikhathi ezi-4-5 ngokushesha kunethusi. Ngasikhathi sinye, isimilo sokugqoka okuncane kanye nokukhiqizwa kwama-electrodes ahlanganisiwe we-graphite kunganciphisa inani le-electrodes, okubuye kunciphise isikhathi sokudla kanye nemishini ye-electrodes. Konke lokhu kunganciphisa kakhulu izindleko zokukhiqiza zokubumba.

I-3, e-edm esheshayo eyakha, ukwanda okuphansi okushisayo, kanye nokulahleka okuphansi

Ngenxa yokuvuselelwa okungcono kwama-electrodes we-graphite uma kuqhathaniswa ne-Copper, ijubane labo lokukhipha liphi izikhathi ezi-4-5 ngokushesha kunethusi. Futhi ingamelana ne-ter yamanje ngesikhathi sokuphuma, okuyinzuzo engcono yokuphuma kukagesi ngogesi. Ngaleso sikhathi, ngevolumu efanayo, isisindo se-electrodes ye-graphite izikhathi ezi-1/5 zethusi, zinciphisa kakhulu umthwalo ku-EDM. Inezinzuzo ezinhle ekukhiqizeni ama-elektrodi amakhulu kanye nama-electrodes wesilisa ahlanganayo. Izinga lokushisa elingaphansi kwe-graphite lingu-4200 ℃, okungukuthi izikhathi ezi-4-5 ezenziwa yi-zethusi (izinga lokushisa elingaphansi kweCopper lingu-1100 ℃). Emazingeni okushisa aphezulu, i-defformation ayincane (1/3 kuya ku-1/5 yethusi ngaphansi kwezimo ezifanayo zikagesi) futhi ayithambisi. Kungakudlulisa kahle nangokufanele ukudlulisela amandla okulahla emsebenzini ngokusetshenziswa okuphansi. Ngenxa yamandla akhuphuke ama-elektrode we-graphite emazingeni okushisa aphezulu, anganciphisa ngempumelelo ukulahleka kokucala (ukulahleka kwe-graphite kungu-1/4 wethusi), uqinisekisa ikhwalithi yokusebenza kokubumba okuqediwe.

Eminyakeni yamuva nje, ngokwethulwa kokubumba okunembile kanye nokukhulisa okusebenzayo okuphezulu (okunamaqhubu amaningi okukhulisa), izidingo zabantu zokukhiqiza isikhunta sezikhulile kakhulu. Ngenxa yokulinganiselwa kwezimo ezahlukahlukene ze-electrodes zethusi, ngeke zisakwazi ukufeza izidingo zentuthuko zemboni yokubumba. Ama-electrodes we-graphite, njengezinto zokwenziwa kwama-elekthrodi e-EDM, asetshenziswe kabanzi embonini yokubumba ngenxa yekhono labo eliphakeme, isisindo esikhanyayo, ukwakheka okusheshayo, isilinganiso esincane sokunwebeka, kanye nokulungiswa okulula. Kuye kwahluleka ukubekezela ukufaka esikhundleni se-electrodes yethusi.
