Kutheni le nto imibhobho yentsimbi kufuneka inyangwe ngobushushu?

Umsebenzi wokunyanga ukushisa kukuphucula izinto eziphathekayo zemibhobho yensimbi, ukuphelisa uxinzelelo olushiyekileyo kunye nokuphucula ukusebenza kwayo kokusika.

Ngokweenjongo ezahlukeneyo zonyango lobushushu, inkqubo yonyango lobushushu inokwahlulwa ibe ngamacandelo amabini: unyango lokuqala lobushushu kunye nonyango lokugqibela.

1. Unyango lwangaphambili lobushushu

Injongo yonyango lwangaphambili lobushushu kukuphucula ukunyanzeliswa, ukuphelisa uxinzelelo lwangaphakathi kunye nokulungiselela isakhiwo esihle se-metallographic kunyango lokugqibela lobushushu. Iinkqubo zayo zokunyanga ukushisa zibandakanya ukucima, ukunyanzeliswa, ukuguga, ukucima kunye nokuvutha, njl.

(1) Ukuhlanjululwa kunye nokuQinisekisa

I-Anealing kunye ne-normalization isetyenziselwa izithuba ezishushu ezisebenzayo. Kwi-carbon steel kunye nentsimbi ye-alloy enomxholo wekhabhoni enkulu kune-0.5%, unyango lwe-annealing luhlala lusetyenziselwa ukunciphisa ubunzima bayo kunye nokulula ukusika; I-carbon steel kunye nentsimbi ye-alloy kunye nomxholo wekhabhoni ngaphantsi kwe-0.5%, unyango oluqhelekileyo luyamkelwa ukwenzela ukuphepha ukunamathela isixhobo ngexesha lokusika. Ihlala icwangciswa emva kokwenziwa okungenanto naphambi komatshini orhabaxa.

(2) Unyango lokwaluphala

Unyango lokuguga lusetyenziselwa ukuphelisa uxinzelelo lwangaphakathi oluveliswa kwimveliso engenanto kunye nomatshini.

Ukuze ugweme ukugqithiswa komsebenzi wokuthuthwa komsebenzi, kumacandelo ngokuchaneka ngokubanzi, unyango lokuguga lunokulungiswa ngaphambi kokugqiba. Nangona kunjalo, kumacandelo aneemfuno zokuchaneka okuphezulu, iinkqubo ezimbini okanye ngaphezulu zonyango oluguga luya kulungiselelwa. Unyango lokuguga alufuneki ngokubanzi kwiindawo ezilula.

(3) Ukulungelelanisa

Ukucima kunye nokufudumala kubhekiselele kunyango oluphezulu lobushushu emva kokucima. Iyakwazi ukufumana i-uniform kunye ne-fine tempered sorbite isakhiwo kwaye ilungiselele ukunciphisa i-deformation ngexesha lokucima umphezulu kunye nonyango lwe-nitriding kwixesha elizayo. Ke ngoko, ukucima kunye nokuthambisa kunokusetyenziswa njengonyango lokuqala lobushushu.

2. Unyango lokugqibela lobushushu

Injongo yonyango lokugqibela lobushushu kukuphucula iimpawu zoomatshini ezifana nobunzima, ukumelana nokunxiba kunye namandla.

(1)Ukucima

Ukucima kubandakanya ukucima umphezulu kunye nokucima okubalulekileyo. Phakathi kwazo, ukucinywa komphezulu kusetyenziswa kakhulu ngenxa ye-deformation yayo encinci, i-oxidation kunye ne-decarburization. Ngaphezu koko, ukucima umphezulu kunezibonelelo zamandla aphezulu angaphandle, ukuxhathisa okulungileyo, ukuqina okulungileyo kwangaphakathi kunye nokuchasana okunamandla.

(2) Ukucinywa kweCarburizing

I-Carburizing kunye nokucima iyasebenza kwi-carbon steel ephantsi kunye nentsimbi ephantsi ye-alloy. Okokuqala, yongeza umxholo wekhabhoni womgangatho ophezulu wamacandelo, kwaye ufumane ubunzima obuphezulu emva kokucima, ngelixa i-core igcina amandla athile kunye nokuqina okuphezulu kunye neplastiki.

(3) Unyango lwe-Nitriding

I-Nitriding yindlela yonyango yokwenza iiathom zenitrogen zingene kumphezulu wesinyithi ukuze zifumane umaleko wemixube enenitrogen. Umaleko we-nitriding unokuphucula ukuqina, ukuxhathisa ukunxiba, amandla okudinwa kunye nokuxhathisa ukubola kwamalungu. Njengoko iqondo lokushisa lonyango lwe-nitriding liphantsi, i-deformation incinci, kwaye i-nitriding layer incinci (ngokuqhelekileyo ayikho ngaphezu kwe-0.6 ~ 0.7mm), inkqubo ye-nitriding kufuneka ihlelwe ngokukhawuleza kangangoko kunokwenzeka. Ukuze kuncitshiswe i-deformation ngexesha le-nitriding, ubushushu obuphezulu bokuphelisa uxinzelelo luyimfuneko ngokubanzi emva kokusika.
