Mi-aterialSunyulo kunyeMukuvelisaPirowusi yeHot FukudibanisaUyafa

Umngundo sisixhobo esibalulekileyo senkqubo yokuqonda itekhnoloji ephezulu yokuvelisa kwinkqubo yokuvelisa, kwaye kwiminyaka yakutshanje, isetyenziswe ngokubanzi kwimveliso yanamhlanje.Ukususela kumbono wokusetyenziswa, umgangatho we-mold uxhomekeke ekukhethweni kwezinto eziphathekayo kunye nenkqubo yonyango lokushisa. Ngokwemiqathango yokusetyenziswa, i-mold yahlulwe ibe ngumbumba obandayo, ukubumba okufudumeleyo, ukubumba okutshisayo, ukubumba iplastiki kunye nokubunjwa kokubumba, njl.

1. Imithetho yokukhetha izinto eziphathekayo kunye nonyango lobushushu iimfuno zobugcisa of forging eshushu uyafa：

Ngokuhlalutya indlela yokungaphumeleli ngokubanzi kokufa okutshisayo, kunokubonwa ukuba ukufa kufuneka kuthathelwe ingqalelo kwinkqubo yokukhethwa kwezinto ezibonakalayo.ukuqina kwe-thermal,ukuqina-ubuchule, amandla kunye nokuqina, ukusebenza kokukhathala kwe-thermalkwaye nangokunjalo. Ukususela kumbono wonyango lokushisa, kuyimfuneko ukuqwalasela ukunyanzeliswa kokugqoka, i-surface decarburization, ubunzima, njl.

Ukuqina kweThermal,ekwabizwa ngokuba yi-red rigidity, ibhekisa kubumba kwindawo yobushushu obuphezulu ukugcina uzinzo lombutho kunye nokusebenza, kunye nokukwazi ukumelana nokuthamba.Olu buchule luxhomekeke ikakhulu ekubunjweni kweekhemikhali zezinto ngokwazo kunye nenkqubo yokunyanga ukushisa. Ngokuqhelekileyo, iintsimbi ezineendawo eziphezulu zokunyibilika ezifana ne-V, W, Co, Nb, Mo kunye nokulula ukwenza izinto ezininzi ze-carbide ziphezulu kubunzima bokushisa.

Amandla kunye nokuqinaziqwalaselwa ngokukodwa ngokuhambelana nomthamo wokubunjwa, ubukhulu bengqolowa yentsimbi, ifom, ukusabalalisa, ubungakanani, ubuninzi be-carbide kunye nomxholo we-austenite eseleyo iya kuchaphazela amandla kunye nokuqina kwesikhunta.Ezi zinto zixhomekeke ikakhulu kukwakheka kweekhemikhali zentsimbi, imeko yombutho kunye nokusetyenziswa okusengqiqweni kwenkqubo yonyango lobushushu.

Ukuqina-ubuchuleibhekisela kuluhlu lobunzima obunokuthi luphunyezwe emva kwenkqubo yokucima izinto eziphathekayo, ezihambelana ngokuthe ngqo nomxholo wekhabhoni wezinto eziphathekayo. Ewe kunjalo, zininzi izinto ezichaphazela ubomi bokufa okutshisayo, kwaye izixhobo kufuneka zikhethwe ngokufanelekileyo ngokwemiqathango yokusetyenziswa kokufa okushushu.

2. Hot forging die processing technology：

Okokuqala, blanking, forging andspheroidizing unyango annealing: Izinto zokubumba ezibonelelwa ngumzi-mveliso wentsimbi ubukhulu becala kwimivalo okanye iibhiliti zokubumba, kwaye i-carbides kwintlangano yangaphakathi isasazwa kwimeko yenethiwekhi ecaleni kwemida yeenkozo. Ukuba izinto zokubumba kule fomu aziqhubeki ngakumbi, ukuqhekeka kulula ukuqaliswa kunye nokwandiswa kunye nemida yeenkozo ngexesha lokwakha, ukunciphisa umthamo wokuthwala isikhunta kwaye ekugqibeleni kuncitshiswe ubomi benkonzo yokubumba.Ngokwenza unyango kunye ne-spheroidizing annealing treatment, encinci, iyunifomu kunye ne-dispersed carbide inokwakheka, iimeko zangaphakathi zombutho wokungunda ziyaphuculwa, kwaye isiganeko esiqhekezayo esibangelwa kugxininiso loxinzelelo lwendawo kwinkqubo yonyango lobushushu luyaphetshwa, kwaye ubomi benkonzo ukungunda kuphuculwe.

Okwesibini, fUkuqala unyango: Lungiselela ukusika ngaphambi kokuba unyango lobushushu, eyona njongo iphambili kukuphepha ukubunjwa koxinzelelo loxinzelelo kumphezulu wesikhunta ngexesha lomatshini kunye nokunciphisa ukudinwa kwesikhunta.Ukulungiswa kwepulse yombane yinkqubo yokunyibilika kwezinto. Emva kokulungiswa kwe-pulse yombane, i-melting layer kunye ne-heat-feed layers yenziwa lula phezu kwendawo yokubumba, enempembelelo ethile kubunzima kunye nokuxhatshazwa kokugqoka kwendawo yokubumba. Ukuze kuncitshiswe uxinzelelo olucinezelayo olwenziwe kumphezulu wokungunda emva konyango lobushushu, ukusetyenzwa kwe-pulse yombane akusaqhutywa emva kokuba unyango lobushushu lugqityiwe, kodwa ngokunciphisa isibonelelo sokusebenza.Okanye sebenzisa indlela yokusila kunye nokupholisha emva kokulungiswa ukunciphisa impembelelo kwi-surface processing layer ukuze ugweme ukusika, ngokukodwa ukulungiswa kwe-pulse yombane kwi-mold surface umonakalo kunye nokuchaphazela ubomi bobumba.

Okwesithathu, unyango lokufudumeza:iteknoloji yokucubungula ingqiqo kufuneka isetyenziswe ukunciphisa ukuguqulwa kwesikhunta kwinkqubo yonyango lokushisa, njengokusetyenziswa kwenkqubo yokufudumala yamanqanaba amaninzi, enokuthintela ukubunjwa kokufudumala. Kwangaxeshanye, indlela yonyango lobushushu kufuneka ithintele ukuphuphuma kwezinto ezixutyiweyo, kwaye ngaphakathi koluhlu oluvumelekileyo lwezinto ezilukhuni, itekhnoloji yokucima igesi kunye nonyango lobushushu kufuneka isetyenziswe kangangoko ukunciphisa ukuguqulwa konyango lobushushu kunye nokuphepha ukwanda kwesibonelelo sokusebenza emva kwekhonkco lokunyanga ukushisa, okubangelwa ukushisa okuphezulu kunye nokuchaphazela ubomi benkonzo yokubumba.

NExt, sukuqhushumba okushushu, ukucola, ukugudisa unyango:emva kokucinywa kunye nenkqubo yokuthoba, ngaphambi konyango lobushushu bomphezulu, ukuchama kufuneka kuqhutywe ukwenza umaleko woxinzelelo olucinezelayo kumphezulu wokufa, ukuze utshintshe imeko yoxinzelelo lomphezulu wokufa emva kokucima kunye nonyango olushushu;unyango lokugudisa umngundo nako ukuphelisa iziphene umphezulu processing umngundo kunye nokuphucula ubomi benkonzo.

Emva koko,Ion nitrogen enzulu: in ukuze kuphuculwe ngakumbi ukuchasana nokukhathala kunye nokuxhatshazwa kokugqoka isikhunta, kungcono ukusebenzisa i-N2 kwaye ugweme i-NH3, kuba i-H + kwi-NH3 inefuthe le-hydrogen embrittlement kwi-mold.Kufuneka kuqatshelwe ukuba ubushushu obunzulu be-nitrogen kufuneka bube ngaphantsi kweqondo lokushisa emva kokucima, ukwenzela ukuba ugweme ukucuthwa kobulukhuni be-mold matrix, okubangela ukusilela kokubumba..

Ekugqibeleni, cunyango ryogenic: tumgaqo wakhe wonyango lwe-cryogenic kukunciphisa i-austenite eshiyekileyo kwaye wenze uxinzelelo olucinezelayo kumphezulu wokungunda ukuphucula ubulukhuni kunye nokumelana nokunxiba kwendawo yokubumba.Kodwa kufuneka ukhuseleke. Inkcazo ngokubanzi yonyango lwe-cryogenic: ngundo (imeko yobushushu begumbi) - i-nitrogen engamanzi (-196) "C / iiyure ezi-2 - ukubuyela kwendalo kwiqondo lokushisa kwe-160-170C / 4 iiyure zokupholisa ezingenanto.

Lilonke, ukwenza ifayidi eshushu yokubumba ayingomsebenzi olula, zininzi iinkcukacha ekufuneka uzithathele ingqalelo kunye nemithetho emininzi ekufuneka iqatshelwe kwaye ilandelwe, ngethemba lokuba olu lwazi lungasentla lunokukunceda ukusa kumlinganiselo othile. Wamkelekile ukuba ushiye imibuzo kunye neengcinga zakho ngezantsi. I-ZZBETTER njengenkampani yobuchwephesha kunye nechule, sikwavelise ii-tungsten carbide ezininzi ezishushu zokufa kunye nezinye iimveliso zeWC, ke nceda uqhagamshelane nathi ukuba unombuzo ngokunjalo.
