Ukwenziwa koTyalo-mali oluLungelelweyo / ukuCasa ngokuchaneka kwezahlulo zempompo ezibonisiweyo

UkuCalwa koTyalo-mali oluLungiselelweyo / aMalungu eMpompo yokuCasa ngokuchanekileyo

I-castin yotyalo-maliInkqubo ye-g ibhekisa ekwenzeni imodeli ngewax, ukusonga umaleko wezinto ezilahlayo ezifana nodongwe ngaphandle, ukufudumeza iwax ukuze inyibilike kwaye iphume, ukuze ufumane iqokobhe elingenanto elenziwe ngezinto ezichasayo, kwaye emva koko ugalele isinyithi.kwiqokobhe elingenanto emva kokunyibilika.Emva kokuba intsimbi ipholile, i-refractory material iyachithwa ukuze ifumane i-mold metal.Le nkqubo yokucubungula isinyithi ibizwa ngokuba yi-investment casting, eyaziwa ngokuba yi-investment casting okanye ukulahleka kwe-wax.

inkqubo yezobuchwepheshe

Inkqubo yetekhnoloji yomzimba wempompo yensimbi engenastainless ngokuchaneka ngolu hlobo lulandelayo:

1. Ngenxa yokungabi namanzi kwentsimbi etyhidiweyo, ukuze kuthintelwe ukuvaleka okubandayo kunye nokugalelwa ngokwaneleyo kweentsimbi zensimbi engenasici, ubukhulu bodonga lwentsimbi yentsimbi akufanele ibe ngaphantsi kwe-8mm;isakhiwo senkqubo yokuthululela kufuneka ibe lula, kwaye ubukhulu becala kufuneka bube bukhulu kunolo lwentsimbi;ukuphosa okomileyo okanye ukuphosa okushushu kufuneka kusetyenziswe.Ukubunjwa kokubumba: Ukunyusa ngokufanelekileyo ubushushu bokuthulula, ngokubanzi 1520 ° ~ 1600 ° C, kuba ubushushu bokugalela buphezulu, ukushisa okukhulu kwentsimbi etyhidiweyo kukhulu, kwaye ixesha lokugcina imeko yolwelo lide.Nangona kunjalo, ukuba iqondo lobushushu lokugalela liphezulu kakhulu, liya kubangela iinkozo ezirhabaxa, iintanda ezishushu, iipores kunye nesanti encangathi.Ngoko ke kwincinci ngokubanzi, ebhityileyo-enodonga kunye nokubunjwa okuyinkimbinkimbi, ubushushu bayo bokugalela bumalunga nenqanaba lokunyibilika kwentsimbi + 150 ℃;kwisakhelo esikhulu esinodonga olungqindilili, ubushushu bayo bokugalela kufuneka bube malunga ne-100 ℃ ngaphezulu kunendawo yokunyibilika kwayo.

2. Ekubeni i-shrinkage ye-stainless steel castings iphezulu kakhulu kuneyentsimbi, ukwenzela ukukhusela i-shrinkage cavities kwi-castings, imilinganiselo efana nokunyuka, isinyithi esibandayo kunye nenkxaso-mali isetyenziswa kakhulu kwinkqubo yokuphosa ukuphumeza ukuqina okulandelelanayo.

Iinzuzo zeMveliso

Ukwenziwa kotyalo-mali kukwabizwa ngokuba yi-precision casting/dewaxing casting.Xa kuthelekiswa nezinye iindlela zokusasa kunye neenxalenye zokwenza iindlela, utyalo-mali losasazo lunezi nzuzo zilandelayo:

1. Ukuchaneka kwe-dimensional of casting kuphezulu, ixabiso le-roughness ye-surface lilungile, ukuchaneka kwe-dimensional ye-casting inokufikelela kumabakala angama-4-6, kunye nobunzima bomhlaba bungafikelela kwi-0.4-3.2μm, enokunciphisa kakhulu isibonelelo sokucubungula. ukuphosa kwaye inokuqonda ukwenziwa kwentsalela.ukunciphisa iindleko zokuvelisa.

2. Iyakwazi ukuphosa ii-castings ezinemilo enzima kwaye kunzima ukuyiqhuba ngezinye iindlela.Ubungakanani be-outline ye-castings busuka kwiimilimitha ezimbalwa ukuya kumawaka eemilimitha, ubuncinci bodonga lobungqimba yi-0.5mm, kwaye ubuncinci bomngxuma we-diameter bungaphantsi kwe-1.0mm.

3. Izinto ze-alloy azikhawulelwanga: izinto ezifana ne-carbon steel, insimbi engenasici, insimbi ye-alloy, i-alloy yobhedu, i-aluminium alloy, i-alloy high-temperature, i-titanium alloy kunye nentsimbi exabisekileyo inokuveliswa ngokuchithwa ngokuchanekileyo.Kwimathiriyeli yealloyi ekunzima ukuyibumba, i-weld kunye nokusika, ngakumbi Ifaneleke ngakumbi kwimveliso yokuphosa echanekileyo.

4. Ukuguquguquka okuphezulu kwemveliso kunye nokuguquguquka okunamandla.Ingasetyenziselwa imveliso yobuninzi kunye nebhetshi encinci okanye imveliso yesiqwenga esinye.

Ukushwankathela, ukuphosa ngokuchanekileyo kuneengenelo zesikali sotyalo-mali oluncinci, umthamo omkhulu wemveliso, ixabiso eliphantsi lemveliso, ukwenziwa lula kwenkqubo yemveliso entsonkothileyo, kunye nembuyekezo ekhawulezileyo kutyalo-mali.Ke ngoko, ikwindawo efanelekileyo kukhuphiswano nezinye iinkqubo kunye neendlela zokuvelisa.
