Ukuphoswa kotyalo-mali, okwakwaziwa njengokuphosa kwe-wax elahlekileyo, kwadalwa kwiminyaka engama-5,000 eyadlulayo.Le ndlela yokuphosa inika iindawo ezichanekileyo, eziphindaphindiweyo kunye neziguquguqukayo ezineentsimbi ezahlukeneyo kunye ne-alloys ephezulu yokusebenza.Le ndlela yokuphosa ifanelekile ukuphosa ivumba kunye namalungu achanekileyo kwaye ibiza kakhulu kunezinye iindlela zokuphosa.Ngokuveliswa ngobuninzi, ixabiso leyunithi liya kuhla.
Inkqubo yotyalo-mali:
Ukwenza iPatheni yeWax: Abavelisi botyalo-mali kufuneka benze iipateni zewax zokusahlela kwabo.Uninzi lweenkqubo zokuphosa utyalo-mali zifuna i-wax ephezulu yokuphosa ukugqiba eli nyathelo.
Indibano yomthi we-wax: Iindleko zokuvelisa imveliso yotyalo-mali enye iphezulu, kwaye kunye nendibano yomthi we-wax, abavelisi bokuphosa utyalo-mali banokudala izivuno ezininzi.
Ukwenza iqokobhe: Yenza iingxowa zeqokobhe kwimithi yewax, ziqiniswe kwaye uzisebenzise kwinkqubo yokuphosa elandelayo.
Ukususwa kwe-wax: Ukususa i-wax ngaphakathi kuya kunika umngxuma apho unokugalela isinyithi esinyibilikisiweyo kwi-casing egqityiweyo.
Iqokobhe lawa: Emva kokuba isinyithi esinyibilikisiweyo siqinile, wisa iqokobhe ukuze ufumane umthi wemveliso yesinyithi.Zisike emthini kwaye uya kuba nemveliso yokugqibela yotyalo-mali.
Iimpawu zobugcisa:
1. Ukuchaneka okuphezulu kwe-dimensional kunye nokuchaneka kwejometri;
2. Uburhabaxa obuphezulu bomphezulu;
3. Iyakwazi ukuphosa i-castings ngeemilo eziyinkimbinkimbi, kwaye ii-alloys eziza kuphoswa azikhawulelwanga.
Ukungalungi: inkqubo enzima kunye neendleko eziphezulu
Isicelo: ilungele ukuveliswa kwamacandelo amancinci aneemilo eziyinkimbinkimbi, iimfuno ezichanekileyo ezichanekileyo, okanye kunzima ukwenza ezinye iinkqubo, ezifana ne-injini ye-injini ye-injini, njl.
1. Iyakwazi ukuphosa i-castings eyinkimbinkimbi yee-alloys ezahlukeneyo, ngakumbi i-superalloy castings.Umzekelo, iprofayili yangaphandle elungelelanisiweyo kunye nokupholisa ngaphakathi kwecango le-injini ye-jet ayinakwenzeka ukuba yenziwe yinkqubo yomatshini.Imveliso yotyalo-mali lwetekhnoloji ye-I ayinakufezekisa imveliso yobuninzi kuphela, iqinisekisa ukuhambelana kokuphosa, kodwa iphinde igweme ukuxinwa koxinzelelo lwemigca ye-blade eseleyo emva komatshini.
2. Ukuchaneka kwe-dimensional ye-investment castings iphezulu kakhulu, ngokubanzi ukuya kuthi ga kwi-CT4-6 (CT10~13 yokuphosa isanti kunye ne-CT5~7 yokuphosa ukufa).Ngokuqinisekileyo, ngenxa yobunzima benkqubo yokuphosa utyalo-mali, kukho izinto ezininzi ezichaphazela ukuchaneka komgangatho wokubunjwa, njengokucutheka kwezinto zokubumba, ukuguqulwa kobumba botyalo-mali, utshintsho oluhambelanayo lweqokobhe lokubumba ngexesha lokubumba. ukufudumeza kunye nenkqubo yokupholisa, ukucutheka kwegolide kunye nokuguqulwa kokuphosa ngexesha lenkqubo yokuqinisa, ukuchaneka komgangatho wotyalo-mali oluqhelekileyo lotyalo-mali luphezulu kakhulu, nangona kunjalo, ukuhambelana kwayo kusafuna ukuphuculwa (ukuhambelana komgangatho wokuphosa okuphakathi kunye nokuphezulu. iwax yobushushu kufuneka iphuculwe kakhulu)
3. Xa ucinezela i-mold investment, i-mold ene-high surface finish of the mold cavity isetyenziswa.Ngoko ke, ukugqitywa komphezulu we-investment mold nako kuphezulu.Ukongeza, igobolondo le-mold yenziwe nge-coating-resistant-resistant coating eyenziwe nge-adhesive ekhethekileyo yobushushu obuphezulu kunye nezixhobo ezichasayo, ezifakwe kwi-investment mold.Ukugqitywa komphezulu womgodi wokungunda ngokuthe ngqo kwintsimbi etyhidiweyo kuphezulu.Ngoko ke, ukugqitywa komphezulu we-investment casting kuphezulu kunezo ziqhelekileyo eziqhelekileyo, ngokubanzi ukuya kwi-Ra.1.3.2 μ m.
4. Eyona nzuzo inkulu yotyalo-mali kukuba ngenxa yokuba utyalo-mali luchaneka ubungakanani obuphezulu kunye nokugqiba komphezulu, kunokunciphisa umsebenzi womatshini.Kuphela isixa esincinci sesibonelelo somatshini sinokushiywa kwiindawo ezineemfuno eziphezulu, kwaye ezinye ii-castings zingasetyenziswa ngaphandle kokulungiswa koomatshini.Ingabonwa ukuba indlela yokuphosa utyalo-mali inokugcina izixhobo ezininzi zoomatshini kunye nexesha lokucubungula, kwaye igcine kakhulu izixhobo zentsimbi.
