Iingenelo ze-electrodes ze-graphite

1: Ubunzima obandayo bejometri yokubumba kunye nokwahlukahluka kwezicelo zemveliso kukhokelele kwiimfuno eziphezulu neziphezulu zokuchaneka komatshini we-spark. Iingenelo zee-electrode ze-graphite kukucubungula okulula, izinga eliphezulu lokususa umatshini wokukhupha umbane, kunye nokulahleka okuphantsi kwe-graphite. Ke ngoko, abanye abathengi bomatshini we-spark abasekwe kwiqela bayawashiya ama-electrode obhedu baze batshintshele kuma-electrode e-graphite. Ukongeza, amanye ama-electrode anomfanekiso okhethekileyo awanakukwenziwa ngobhedu, kodwa i-graphite kulula ukuyibumba, kwaye ama-electrode obhedu anzima kwaye awafanelekanga ukucutshungulwa kwama-electrode amakhulu. Ezi zinto zibangele ukuba abanye abathengi bomatshini we-spark abasekwe kwiqela basebenzise ama-electrode e-graphite.

2: Ii-electrode zeGraphite kulula ukuzicubungula, kwaye isantya sokucubungula sikhawuleza kakhulu kunee-electrode zobhedu. Umzekelo, ukusebenzisa iteknoloji yokugaya ukucubungula i-graphite, isantya sayo sokucubungula sikhawuleza ngokuphindwe ka-2-3 kunezinye iindlela zokucubungula isinyithi kwaye ayifuni ukucubungula okongeziweyo ngesandla, ngelixa ii-electrode zobhedu zifuna ukugaywa ngesandla. Ngokufanayo, ukuba iziko lokugaya i-graphite elikhawulezayo lisetyenziselwa ukwenza ii-electrode, isantya siya kuba sikhawuleza kwaye ukusebenza kakuhle kuya kuba phezulu, kwaye akuyi kubakho ngxaki zothuli. Kule nkqubo, ukukhetha izixhobo ezinobunzima obufanelekileyo kunye ne-graphite kunokunciphisa ukuguguleka kwezixhobo kunye nomonakalo wobhedu. Ukuba uthelekisa ngokukodwa ixesha lokugaya lee-electrode ze-graphite kunye nee-electrode zobhedu, ii-electrode ze-graphite zikhawuleza ngama-67% kunee-electrode zobhedu. Ngokubanzi kwi-electrical discharge machining, ukucubungulwa kwee-electrode ze-graphite kukhawuleza ngama-58% kunee-electrode zobhedu. Ngale ndlela, ixesha lokucubungula liyancipha kakhulu, kwaye iindleko zokuvelisa nazo ziyancitshiswa.

3: Uyilo lwe-graphite electrode lwahlukile kolo lwe-electrode yobhedu yendabuko. Iifektri ezininzi ze-mold zihlala zinezibonelelo ezahlukeneyo zokurhawuzelela nokugqiba ii-electrode zobhedu, ngelixa ii-electrode ze-graphite zisebenzisa izibonelelo ezifanayo. Oku kunciphisa inani le-CAD/CAM kunye nokucutshungulwa koomatshini. Ngenxa yesi sizathu sodwa, Kwanele ukuphucula ukuchaneka kwe-mold cavity kakhulu.

Kakade ke, emva kokuba ifektri yesikhunta itshintshele kwi-electrodes zobhedu ukuya kwi-electrodes ze-graphite, into yokuqala ekufuneka icace kukuba zisetyenziswa njani izinto ze-graphite kwaye iqwalasele ezinye izinto ezinxulumene noko. Kule mihla, abanye abathengi bomatshini we-spark osekwe kwiqela basebenzisa i-graphite ukwenza i-electrode discharge machining, nto leyo ephelisa inkqubo yokupholisha i-mold cavity kunye ne-chemical polishing, kodwa isafezekisa ukugqitywa komphezulu okulindelekileyo. Ngaphandle kokwandisa ixesha kunye nenkqubo yokupholisha, akunakwenzeka ukuba i-electrode yobhedu ivelise umsebenzi onjalo. Ukongeza, i-graphite yahlulwe ngokwamanqanaba ahlukeneyo. Isiphumo esifanelekileyo sokucubungula sinokufezekiswa ngokusebenzisa amanqanaba afanelekileyo eeparamitha zokukhupha i-graphite kunye ne-electric spark phantsi kwezicelo ezithile. Ukuba umqhubi usebenzisa iiparamitha ezifanayo ne-electrode yobhedu kumatshini we-spark usebenzisa ii-electrodes ze-graphite, ke isiphumo kufuneka sibe yinto edanisayo. Ukuba ufuna ukulawula ngokungqongqo izinto ze-electrode, ungayibeka i-electrode ye-graphite kwimeko yokungalahleki (ukulahleka okungaphantsi kwe-1%) ngexesha lokwenziwa kwe-rough machining, kodwa i-electrode yobhedu ayisetyenziswa.

I-Graphite ineempawu ezilandelayo ezikumgangatho ophezulu ezingenakulinganiswa nobhedu:

Isantya sokucubungula: ukugaya okurhabaxa ngesantya esiphezulu kukhawuleza ngokuphindwe kathathu kunethusi; ukugqiba ukugaya ngesantya esiphezulu kukhawuleza ngokuphindwe kahlanu kunethusi

Ukusebenza kakuhle, inokufezekisa ukumodela okuntsonkothileyo kwejometri

Ubunzima obulula, ubuninzi bungaphantsi kwe-1/4 yobhedu, i-electrode kulula ukuyibamba

inokunciphisa inani lee-electrode ezingatshatanga, kuba zinokuhlanganiswa zibe yi-electrode edibeneyo

Uzinzo oluhle lobushushu, akukho tshintsho kwaye akukho ziqhushumbisi zokucubungula
