Inkqubo Yokusebenza kunye neenkcukacha Zobuchwephesha zeumatshini wokubumba isanti
Ukulungiswa kweMbumba
Iimold ze-aluminium alloy okanye ze-ductile iron ezikumgangatho ophezulu zenziwa ngokuchanekileyo ngeenkqubo ze-CNC ze-5-axis, zifikelela kuburhabaxa bomphezulu obungaphantsi kwe-Ra 1.6μm. Uyilo lohlobo oluqhekekileyo lubandakanya ii-engile ze-draft (ngesiqhelo i-1-3°) kunye nezibonelelo zoomatshini (0.5-2mm) ukuze kube lula ukususwa. Izicelo zoshishino zihlala zisebenzisa iimold ezigqunywe nge-zirconia-based refractory layers ukwandisa ubomi benkonzo ngaphaya kwemijikelo engama-50,000.
Ukuzaliswa kweSand kunye nokuBumba
Isanti yesilika ebotshelelwe ngamakhemikhali (85-95% SiO₂) ixutywe nodongwe lwe-bentonite oluyi-3-5% kunye namanzi ayi-2-3% ukuze kubekho amandla aluhlaza afanelekileyo. Oomatshini bokubumba abazenzekelayo abasebenzisa i-flaskless molding bafaka uxinzelelo lokuxinana lwe-0.7-1.2 MPa, nto leyo efikelela kubunzima bokubumba obuyi-85-95 kwisikali se-B. Kwii-engine block castings, ii-sodium silicate-CO₂ harded cores ezinee-venting channels zifakwa ngaphambi kokuba kuvalwe ukubumba.
Ukuhlanganiswa kweMold kunye noLungiso
Iinkqubo zokubona zerobhothi zilungelelanisa iinxalenye zesikhunta ngaphakathi kokunyamezelana kwe-±0.2mm, ngelixa izikhonkwane zokufumana indawo ezidibeneyo zigcina ubhaliso lwenkqubo yokuvala. Ii-C-clamps ezinzima zinamandla okubamba angama-15-20kN, ongezelelweyo ziibhloko zobunzima beesikhunta ezinkulu (>500kg). Ii-Foundries zisebenzisa ngakumbi ukukhiya kwe-electromagnetic kwimveliso ephezulu.
Ukuthulula
Iifurni ezilawulwa yikhompyutha zokufunxa amanzi zigcina ubushushu obukhulu besinyithi kuma-50-80°C ngaphezu kobushushu be-liquidus. Iinkqubo eziphambili zinezinzwa ze-laser kunye neegeyithi zokuhamba ezilawulwa yi-PID, zifikelela kuzinzo lwesantya sokuthulula ngaphakathi kwe-±2%. Kwii-alloys ze-aluminium (A356-T6), isantya sokuthulula esiqhelekileyo siqala kwi-1-3 kg/sec ukunciphisa i-turbulence.
Ukupholisa kunye nokuqinisa
Ixesha lokuqina lilandela umthetho kaChvorinov (t = k·(V/A)²), apho amaxabiso e-k ahluka ukusuka kwi-0.5 min/cm² kwiindawo ezincinci ukuya kwi-2.5 min/cm² kwiindawo ezixineneyo. Ukubekwa ngokucwangcisiweyo kwee-exothermic risers (15-20% yomthamo we-casting) kulungisa ukuncitshiswa kwiindawo ezibalulekileyo.
Ukuxukuxa kunye nokucoca
Ii-conveyor ezingcangcazelayo ezine-5-10G acceleration zahlula i-90% yesanti ukuze kubuyiselwe ubushushu. Ukucoca ngamanqanaba amaninzi kubandakanya ii-tumblers ezijikelezayo zokususa ukuqhushumba kokuqala, kulandele i-robotic abrasive blasting esebenzisa i-0.3-0.6mm steel grit kwi-60-80 psi.
Ukuhlolwa kunye nokuCwangciswa emva kokwenziwa
Oomatshini bokulinganisa abadibeneyo (CMM) baqinisekisa ubungakanani obubalulekileyo ngokwemigangatho ye-ISO 8062 CT8-10. I-X-ray tomography ibona iziphene zangaphakathi ukuya kwisisombululo se-0.5mm. Unyango lobushushu lwe-T6 lwe-aluminium lubandakanya ukunyibilikisa isisombululo kwi-540°C±5°C kulandele ukuguga okwenziweyo.
Iingenelo ezingundoqo:
Ukuguquguquka kwejiyometri okuvumela izakhiwo ezingenanto (umz., ii-impellers zepompo ezinobukhulu bodonga obuyi-0.5mm)
Ukuguquguquka kwezinto ezibonakalayo eziquka ii-alloys ze-ferrous/non-ferrous (i-HT250 grey iron ukuya kwi-AZ91D magnesium)
Iindleko zezixhobo eziphantsi ezingama-40-60% xa kuthelekiswa ne-die casting yeeprototypes
Imida kunye nokunciphisa:
Ubunzima babasebenzi buncitshiswe ngeenkqubo zokuphatha isanti ezenzekelayo
Ukulahlwa kwesikhunta kujongwane namazinga okubuyiselwa kwesanti angama-85-90%.
Imida yokugqiba umphezulu (Ra 12.5-25μm) yoyiswa yimishini echanekileyo
