Kukho iinkqubo ezininzi ezahlukeneyo zokwenza isinyithi. Ngokwesiqhelo, iibhilethi zesinyithi ziyafudunyezwa kwaye zithambe, okwenza ukucutshungulwa kwesinyithi kube lula kwaye kuphucule iipropati zoomatshini zezixhobo. Ezinye iinkqubo zikwabumba isinyithi kubushushu begumbi.
Makhe sijonge iingenelo kunye nokungalungi kwe-hot rolling, i-cold rolling, i-hot heading, kunye ne-cold heading, sigxile ekusebenziseni kwazo kwi-stainless steel bars, i-alloy fasteners, kunye nezinto ezenziwe ngobuchule.
Yintoni iHot Rolling?
Kwiqondo lobushushu begumbi, intsimbi kunzima ukuyiguqula nokuyicubungula. Nangona kunjalo, xa i-billet ishushu kwaye ithambile ngaphambi kokuqengqeleka, inkqubo iba lula kakhulu—oku kubizwa ngokuba yi-hot rolling. I-hot rolling ineenzuzo ezininzi. Okokuqala, amaqondo obushushu aphezulu ayayithambisa intsimbi, okwenza kube lula ukutshintsha isakhiwo sayo kunye nokuphucula iinkozo zayo, ngaloo ndlela iphucula iimpawu zayo zoomatshini. Ukongeza, iziphene zangaphakathi ezifana namaqamza, imifantu, kunye ne-porosity zinokudityaniswa phantsi kobushushu obuphezulu kunye noxinzelelo. Oku kwenzaishushu-iqengqelekaimivalo yentsimbi engagqwaliyoilungele ukusetyenziswa kwesakhiwo esifuna ukuqina okuphuculweyo kunye nokuqina. Nangona kunjalo, ukuqengqeleka okushushu nako kuneengxaki. Ukungcola okuqokelelene kwintsimbi ekuqaleni kunokucinezelwa kube ziingqimba ezincinci endaweni yokudibana nentsimbi, nto leyo ekhokelela ekuqhekekeni. Ngokuhamba kwexesha, oku kunokubangela ukuqhekeka kunye nokuqhekeka, okuchaphazela amandla esinyithi. Ngaphezu koko, ngexesha lenkqubo yokupholisa emva kokuqengqeleka, ukupholisa okungalinganiyo phakathi kweengqimba zangaphakathi nezangaphandle kunokubangela ukuguquka, amandla okudinwa aphantsi, kunye nezinye iziphene.
Yintoni iCold Rolling?
Ukuqengqeleka okubandayo kudla ngokubhekisa ekusebenziseni amandla angaphandle kwisinyithi kubushushu begumbi ukuze kucinezelwe ubukhulu obuthile. Nangona kunjalo, akulunganga ukucinga ukuba ukuqengqeleka okushushu kubandakanya ukufudumeza ngelixa ukuqengqeleka okubandayo kungenzi njalo. Ngokuxhomekeke kwizinto ezisetyenzisiweyo, ukuqengqeleka okubandayo kunokubandakanya ukufudumeza okuthile. Umahluko ophambili kukuba ukuba ukuqhubekeka kwenzeka ngaphantsi kobushushu bokuphinda kusetyenziswe, kuthathwa njengokuqengqeleka okubandayo; ukuba kungaphezulu, kukuqengqeleka okushushu. Iingenelo zokuqengqeleka okubandayo ziquka isantya esiphezulu, ukusebenza kakuhle kwemveliso, kunye nokukwazi ukugcina ingqibelelo yokugquma. Ukuqengqeleka okubandayo kunokudala iimilo ezahlukeneyo ezinqamlezileyo ukuhlangabezana neemfuno ezahlukeneyo zokusetyenziswa kunye nokuphucula ukuguquka kwesinyithi ngeplastiki. I-alloy eqengqelekayo ebandayoamashiti entsimbikunye nokuchanekaimicu yentsimbi engatyiwayozisetyenziswa kakhulu kumashishini eenqwelo-moya, iimoto, kunye ne-elektroniki apho ukuchaneka kobukhulu kunye nomgangatho womphezulu kubalulekile. Nangona kunjalo, uxinzelelo lwangaphakathi oluseleyo kwintsimbi eqengqelekayo ebandayo lunokuchaphazela amandla apheleleyo okanye asekuhlaleni. Ukongeza, izinto eziqengqelekayo ezibandayo zihlala zinobukhulu obuncinci kunye nomthamo ophantsi wokuthwala umthwalo.
Yintoni iCold Heading?
I-cold heading, eyaziwa ngokuba yi-cold forming, yinkqubo apho isinyithi sibunjwa sibe yimo ethile ngaphakathi kwi-die ngokusebenzisa amandla okubetha ngaphandle kokufudumeza. I-cold heading ineenzuzo ezininzi. Ekubeni i-billet icinezelwe ngokupheleleyo kwi-die, akukho nkunkuma ininzi okanye akukho nto ifunekayo ngexesha lokucubungula. Ikwavumela ukuveliswa ngokuzenzekelayo, idla amandla amancinci njengoko kungekho kufudumeza kufunekayo, kwaye isusa isidingo senkqubo yokupholisa, okwenza imveliso ikhawuleze kwaye inciphise iindleko. Oku kwenza ukuba i-cold heading ibe yimeko ebandayo.izibophelelonjengeiibholiti zentsimbi engagqwaliyo, amantongomane, kunye neerivets ezisebenza kakuhle kakhulu kwimveliso enkulu ngaphandle kwenkunkuma eninzi yezinto eziphathekayo. Nangona kunjalo, eminye imisebenzi yokulungisa iintloko ezibandayo ayinakugqitywa ngenyathelo elinye. Endaweni yoko, umsebenzi kufuneka ukhutshwe ngokuthe ngcembe kwiidayi ezahlukeneyo, kufuna amanqanaba amaninzi ukuze kufezekiswe imo oyifunayo. Ukongeza, izinto ezisetyenziselwa ukulungisa iintloko ezibandayo azinakuba nzima kakhulu.
Yintoni iHot Heading?
I-hot heading yinkqubo apho isinyithi siqala sifudunyezwe kwaye sithambe, emva koko siguqulwe ngokweplastiki kusetyenziswa amandla okubetha. I-hot heading inokuphucula kakhulu ulwakhiwo lwangaphakathi kunye neempawu zoomatshini zesinyithi, iphucula amandla ayo kunye ne-plasticity. Ikwanciphisa ubunzima bokucubungula kwaye yonyusa ukusebenza kakuhle kwemveliso. Izibophelelo zentsimbi ye-alloy ene-hot-headed zisetyenziswa kakhulu kwizicelo ezifuna amandla aphezulu, njenge-aerospace, oomatshini abanzima, kunye nolwakhiwo. Nangona kunjalo, i-hot heading ifuna utyalo-mali olukhulu kwizixhobo zokufudumeza kunye namandla, okwenza iindleko zayo zemveliso zibe phezulu kakhulu kune-cold heading.
Ngokuqonda iingenelo kunye nemida yezi ndlela zokwenza isinyithi, abavelisi banokukhetha eyona ndlela ifanelekileyo.
