1. IiNgcaciso zeNkqubo
1.1 Kucetyiswa ukuba kusetyenziswe inkqubo yokufogina ethe nkqo ye-closed-die ukuqinisekisa ukuhanjiswa okulungelelanisiweyo ecaleni kwemilo yangaphandle yenxalenye efojiweyo.
1.2 Inkqubo eqhelekileyo yokuhamba iquka ukusika izinto eziphathekayo, ukusabalalisa ubunzima, ukudubula ukudubula, ukuthambisa kwangaphambili, ukufudumeza, ukukhwabanisa, ukunyanga ukushisa, ukucocwa komhlaba, ukuhlolwa kwe-particle magnetic, njl.
1.3 Isikhululo esinye sokubumba kubhetele xa sisenza. 1.4 Izinto eziphathekayo kufuneka zikhethwe kwi-45 # insimbi, i-20CrMo, i-42CrMo yensimbi, kunye nezinye izinto ezifanayo.
1.5 Kucetyiswa ukuba kusetyenziswe umatshini wokusika ukusika izinto zokususa iintloko kunye nomsila.
1.6 I-Hot-rolled bar stock ekhethwayo.
1.7 Ukuqinisekisa ukuba umkhiqizo uzaliswe ngokupheleleyo kwaye uphucule ubomi bokufa, kucetyiswa ukuba kusetyenziswe oomatshini bokuhlela ubunzima bezigaba ezininzi ukuhlula izinto eziphosakeleyo ngomgangatho.
1.8 Iimathiriyeli ezineziphene kufuneka zidutyulwe ngokuqhushumba kwangaphambili. Ukukhethwa kwesixhobo sokuqhumisa, esifana nedayamitha efanelekileyo yokudubula (malunga ne-Φ1.0mm ukuya ku-Φ1.5mm), kufuneka kuthathelwe ingqalelo iimeko ezinje ngeemfuneko zomphezulu weebhilithi, ubuninzi bezithonga kumjikelo ngamnye, ixesha lokudubula, kunye nobomi bokudubula.
1.9 Iqondo lokushisa langaphambili lezinto ezineziphene kufuneka libe phakathi kwe-120℃ ukuya kwi-180℃.
1.10 Ukugxininiswa kwegraphite kwangaphambili kufuneka kugqitywe ngokusekelwe kuhlobo lwegraphite, umgangatho womgangatho we-forgings, ukushisa ukushisa kunye nobude.
1.11 Igraphite kufuneka itshizwe ngokufanayo kumphezulu wezinto ezineziphene ngaphandle kokuhlangana.
1.12 Igraphite kufuneka ikwazi ukumelana namaqondo obushushu amalunga ne-1000℃ ±40℃.
1.13 Ii-furnaces zokufudumeza ze-Medium-frequency induction zicetyiswa kwizixhobo zokufudumeza.
1.14 Ixesha lokufudumala lezinto eziphosakeleyo linokumiselwa ngokusekelwe kwisixhobo sokufudumeza, ubungakanani be-billet, kunye nesantya sokuvelisa, esijolise ekufezekiseni ukushisa okufanayo kwi-forging ukuqaliswa.
1.15 Ukukhethwa kobushushu bokushisa kwizinto eziphosakeleyo kufuneka kube negalelo ekuphuculeni ukubunjwa kwezinto eziphathekayo kunye nokufumana isakhiwo esilungileyo se-post-forging kunye nomgangatho ophezulu.
- Ukuqulunqa
2.1 Ukukhethwa kweendawo zokwahlula kwi-forging kufuneka kube lula ukususwa kwesikhunta, ukuzaliswa kwesinyithi kwi-cavity, kunye nokulungiswa kwe-mold.
2.2 Uhlalutyo lweenombolo zokulinganisa kufuneka lusetyenziswe ukubala amandla okuguqula kunye nokuthintela ngexesha lokuqulunqa.
2.3 Uluhlu lweqondo lokushisa kwangaphambili kwi-molds ngokuqhelekileyo luphakathi kwe-120℃ kunye ne-250℃, kunye nexesha elincinci lokufudumala lemizuzu engama-30. Ubushushu bomngundo akufunekanga budlule kwi-400℃ ngexesha lenkqubo yemveliso.
