Kwiminyaka yakutshanje, ngokusetyenziswa kakhulu kwee-graphite molds, ixabiso lonyaka lokusetyenziswa kwee-molds kushishino loomatshini liphindwe kahlanu kunexabiso lilonke lazo zonke iintlobo zezixhobo zoomatshini, kwaye ukulahleka okukhulu kobushushu nako kuchasene kakhulu nemigaqo-nkqubo ekhoyo yokonga amandla eTshayina. Ukusetyenziswa okukhulu kwee-molds akunyusi nje ngokuthe ngqo iindleko zamashishini, kodwa kukhokelela ekuvalweni rhoqo kwemigca yemveliso ngenxa yokutshintshwa rhoqo kwee-molds, ekugqibeleni kubangele ilahleko enkulu kwezoqoqosho.
Ngokophando, ngenxa yezinto ezisetyenziswa ekubumbeni kunye namaxabiso amandla anyuke kakhulu kunye nezinye izizathu, inzuzo yemveliso yoshishino lokubumba yehle kunyaka ophelileyo; Ukuze kuhlale kukho kwaye kuphuhliswe, amashishini amaninzi asebenzisa
Ukutshintsha kwezinto kusetyenziswa njengendlela enkulu yokulinganisa utshintsho nophuhliso. Kuyaqondakala ukuba iinkampani ezininzi ziqalise izixhobo zokukhupha iintlantsi zegrafiti, kwaye kwimveliso yesikhunta kudlala indima ebaluleke kakhulu. Xa kuthelekiswa nesikhunta sobhedu sendabuko, izinto zegrafiti zineengenelo zokuchaneka okuphezulu koomatshini kunye nesiphumo esihle somphezulu, ingakumbi ekucutshungulweni komngxuma wesikhunta, udonga oluntsonkothileyo, olubhityileyo, kunye nezinto ezinzima kakhulu zinenzuzo enkulu. Xa kuthelekiswa nobhedu, izinto zegrafiti zineengenelo ezifana nokusetyenziswa kancinci, isantya sokukhupha ngokukhawuleza, ubunzima obuphantsi kunye ne-coefficient encinci yokwandisa ubushushu, ngoko ke i-electrode yobhedu iye yaba yinto ephambili kwizinto zokucubungula ukukhupha. Ngokwahlukileyo koko, izinto ze-graphite electrode zineengenelo ezintandathu ezilandelayo:
1. Isantya esikhawulezayo; Ukukhupha i-graphite kukhawuleza ngokuphindwe kabini ukuya kathathu kune-copper, kwaye izinto azilula ukuziguqula. Zineengenelo ezicacileyo ekucutshungulweni kwe-electrode eqinisiweyo ebhityileyo. Indawo yokuthambisa yobhedu imalunga ne-1000 degrees, kwaye kulula ukuyiguqula ngenxa yobushushu.
2. Ubunzima obulula; Ubunzima begrafiti yi-1/5 kuphela yobo bekopolo. Xa i-electrode enkulu icutshungulwa ngokukhupha, umthwalo wesixhobo somatshini (i-EDM) unokunciphisa ngempumelelo, nto leyo efanelekileyo ngakumbi ekusetyenzisweni kwesikhunta esikhulu.
3. Inkcitho encinci; Njengoko ioyile yentlantsi ineeathom ze-C, ubushushu obuphezulu bubangela ukuba iiathom ze-C kwioyile yentlantsi zibole ngexesha lokucubungula ukukhupha, kwaye ifilimu ekhuselayo yenziwa phezu komphezulu we-graphite electrode, ehlawulela ukulahleka kwe-graphite electrode.
4. Akukho zibher; Emva kokuba i-electrode yobhedu isetyenzisiwe, iibher kufuneka zisuswe ngesandla. Nangona kunjalo, akukho zibher emva kokuba i-graphite isetyenzisiwe, nto leyo engagcini nje ngokusindisa iindleko ezininzi kunye namandla abasebenzi, kodwa ikwanceda ukwenza imveliso ezenzekelayo ibe lula.
5. Ukupholisha okulula; Ngenxa yokuba ukumelana nokusika kwegrafiti yi-1/5 kuphela yobhedu, kulula ukuyicola nokuyipolisha ngesandla.
Vi. Ixabiso eliphantsi; Ngenxa yokunyuka kwexabiso lobhedu kwiminyaka yakutshanje, ixabiso legrafiti kuzo zonke iinkalo liphantsi kunelobhedu. Phantsi komthamo ofanayo wobuninzi bekhabhoni yaseMpuma, ixabiso leemveliso zegrafiti liphantsi ngama-30% ukuya kuma-60% kunelobhedu, ixabiso lizinzile, kwaye ukuguquguquka kwamaxabiso kwexesha elifutshane kuncinci. Njengoko ulondolozo lwamandla, ukhuseleko lokusingqongileyo kunye nokusebenza kakuhle kokucubungula kuba yinto ephambili kushishino lokuvelisa, izixhobo ze-graphite electrode ziya kuthatha indawo ye-electrode yobhedu kancinci kancinci kwaye zidlale indima ebalulekileyo kwi-EDM. Ngokufanayo, kukhuphiswano oluya lukhula ngamandla kwimarike yokubumba namhlanje, ukusetyenziswa kwetekhnoloji yokucubungula ephucukileyo ukuphuhlisa iimveliso zokubumba ezikumgangatho ophezulu yeyona ndlela ilungileyo yokuba amashishini aphumelele kwimarike nakubathengi.
