Kwiminyaka yakutshanje, kunye nokusetyenziswa ngokubanzi kwe-graphite molds, ixabiso lonyaka lokusetyenziswa kwe-molds kumashishini oomatshini ngamaxesha angama-5 exabiso elipheleleyo lazo zonke iintlobo zezixhobo zoomatshini, kwaye ilahleko enkulu yobushushu nayo ichasene kakhulu namandla akhoyo. -imigaqo-nkqubo yokulondoloza e-China.Ukusetyenziswa okukhulu kwe-molds akugcini nje ukwandisa iindleko zamashishini, kodwa kukhokelela ekuvalweni komgca wemveliso rhoqo ngenxa yokutshintshwa rhoqo kweembumba, ekugqibeleni kubangele ilahleko enkulu yezoqoqosho.
Ngokutsho kophando, ngenxa yezixhobo zomngundo kunye namaxabiso amandla enyuka ngokukhawuleza kunye nezinye izizathu, inzuzo yemveliso yemveliso yokungunda yawa kunyaka ophelileyo; Ukuze uphile kwaye uphuhlise, amashishini amaninzi amkela.
Ukutshintsha kwezinto kusetyenziswa njengomlinganiselo omkhulu wotshintsho kunye nophuhliso.Kuyaqondwa ukuba iinkampani ezininzi ziqalise izinto zokukhupha i-graphite spark, kwimveliso yokubumba idlala indima ebaluleke kakhulu. ukuchaneka kwe-machining kunye nesiphumo esihle somgangatho ophezulu, ngokukodwa kwi-processing ye-mold cavity yokuchaneka, i-complex, udonga oluncinci, izinto eziphezulu ezinzima zinenzuzo enkulu.Xa kuthelekiswa nobhedu, izinto zegraphite zineenzuzo ezifana nokusetyenziswa okuncinci, isantya sokukhupha ngokukhawuleza, ubunzima obulula kunye nomncinci. I-coefficient yokwandisa i-thermal, ngoko ke i-electrode yobhedu iye ngokuthe ngcembe yaba yeyona nto iphambili kwizinto ezisetyenziswayo zokukhupha. Ngokwahlukileyo koko, izixhobo ze-graphite electrode zineenzuzo ezintandathu zilandelayo:
1. Isantya esikhawulezayo; Ukukhutshwa kwegraphite kumaxesha angama-2-3 ngokukhawuleza kunobhedu, kwaye izinto eziphathekayo akulula ukuzikhubaza.Ineenzuzo ezicacileyo ekusetyenzweni kwe-electrode eyomeleziweyo encinci.Indawo yokuthambisa yobhedu ijikeleze i-1000 degrees, kwaye kulula ukuyikhubaza ngenxa yobushushu.
2. Ubunzima obulula;Ubuninzi begraphite yi-1/5 kuphela yobhedu.Xa i-electrode enkulu icutshungulwa ngokukhutshwa, umthwalo wesixhobo somatshini (EDM) unokuncitshiswa ngokufanelekileyo, okulungele ngakumbi ukusetyenziswa kwesikhunta esikhulu.
3. Inkcitho encinci; Njengoko i-oyile yentlantsi ine-athom ze-C, ubushushu obuphezulu bubangela ukuba iiathom ze-C ezikwi-spark oil zibole xa kusenziwa ulwelo, kwaye kwenziwa ifilim ekhuselayo kumphezulu we-graphite electrode, ehlawulela ukulahleka kwe-electrode yegraphite.
4. Akukho burrs;Emva kokuba i-electrode yobhedu icutshungulwe, ii-burrs kufuneka zisuswe ngesandla.Nangona kunjalo, akukho burrs emva kokuba i-graphite icutshungulwe, engagcini nje kuphela iindleko ezininzi kunye nabasebenzi, kodwa yenza kube lula ukuqonda imveliso ezenzekelayo.
5. Ukupholisha okulula;Kuba ukuxhathisa ukusika kwegraphite yi-1/5 kuphela yobhedu, kulula ukuguba kunye nokupolisha ngesandla.
Vi.Ixabiso eliphantsi;Ngenxa yokunyuka kwexabiso lobhedu kwiminyaka yakutshanje, ixabiso legraphite kuzo zonke iinkalo lingaphantsi kwelo lobhedu.Ngaphantsi komthamo ofanayo wendalo yonke yekhabhoni yaseMpuma, ixabiso leemveliso zegraphite lisezantsi ngama-30% ukuya kuma-60% Ixabiso lobhedu, ixabiso lizinzile, kwaye ukuguquguquka kwexabiso lexesha elifutshane kuncinci.Ngokongiwa kwamandla, ukhuseleko lokusingqongileyo kunye nokusebenza kakuhle kokusebenza kuba yingqwalasela yoshishino lokuvelisa, izinto ze-graphite electrode ziya kuthatha indawo ye-electrode yobhedu kwaye idlale indima ebalulekileyo. Indima kwi-EDM.Ngokufanayo, ekukhuphisaneni okunyukayo kwimarike yokubumba namhlanje, ukusetyenziswa kobugcisa obuphambili bokucwangcisa ukuphuhlisa iimveliso zomgangatho ophezulu yindlela efanelekileyo yokuba amashishini aphumelele imarike kunye nabathengi.
