Ngaphambi kokuba abanye abathengi baye babonisana malunga ne-titanium alloy, kwaye bacinga ukuba ukusetyenzwa kwe-titanium alloy kunzima kakhulu.Ngoku, oogxa be-RSM Technology Department baya kukwabelana nawe ukuba kutheni sicinga ukuba i-titanium alloy yinto enzima ukuyiqhuba?Ngenxa yokungabikho kokuqonda okunzulu kwendlela yokucubungula kunye nesiganeko.
1. Iziganeko ezibonakalayo ze-titanium processing
Amandla okusika we-titanium alloy iphezulu kancinane kunentsimbi enobunzima obufanayo, kodwa into ebonakalayo ye-titanium alloy processing inzima kakhulu kunokusebenza kwentsimbi, eyenza ukuba ukusetyenzwa kwe-titanium alloy kujongane nobunzima obukhulu.
I-thermal conductivity ye-titanium alloys iphantsi kakhulu, kuphela i-1/7 yensimbi kunye ne-1/16 ye-aluminium.Ngoko ke, ubushushu obuveliswe kwinkqubo yokusika i-titanium alloy ayiyi kudluliselwa ngokukhawuleza kwi-workpiece okanye ithathwe yi-chips, kodwa iya kugxininiswa kwindawo yokusika, kwaye ubushushu obuveliswayo bunokuphakama njenge-1000 ℃ okanye ngaphezulu. ukuze umphetho wokusika wesixhobo unokunxiba ngokukhawuleza, uqhekeke kwaye uvelise amathumba e-chip accretion.Umphetho wokusika okhawulezayo unokwenza ubushushu obuninzi kwindawo yokusika, unciphise ngakumbi ubomi besixhobo.
Ubushushu obuphezulu obuveliswe kwinkqubo yokusika kwakhona buyatshabalalisa ingqibelelo yomphezulu weengxenye ze-titanium ingxubevange, ekhokelela ekunciphiseni ukuchaneka kwejometri yamacandelo kunye nokuvela komsebenzi onzima owenzela ukunciphisa amandla abo okukhathala.
I-elasticity ye-titanium alloy inokuba luncedo ekusebenzeni kwamacandelo, kodwa kwinkqubo yokusika, i-deformation elastic ye-workpiece sisizathu esibalulekileyo sokungcangcazela.Uxinzelelo lokusika lenza ukuba i-workpiece "elastic" ihluke kwisixhobo kunye ne-rebound, ukwenzela ukuba ingxabano phakathi kwesixhobo kunye ne-workpiece inkulu kunomphumo wokusika.Inkqubo yokukhuhlana ivelisa ubushushu, nto leyo eyenza kube mandundu ukungahambi kakuhle kwe-thermal ye-titanium alloys.
Le ngxaki iya iba mandundu ngakumbi xa kusetyenzwa iindawo ezinodonga olucekethekileyo okanye ezimilise umsesane ezinokukhubazeka ngokulula.Akukho lula ukwenza umatshini we-titanium alloy alloy iinxalenye ezicekethekileyo zokuchaneka okulindelweyo.Njengoko i-workpiece material igxothwa ngesixhobo, i-deformation yendawo yodonga oluncinci lugqithise uluhlu lwe-elastic kunye ne-deformation yeplastiki eyenzekayo, kwaye amandla ezinto eziphathekayo kunye nobunzima kwindawo yokusika yanda kakhulu.Ngeli xesha, isantya sokusika esichazwe ekuqaleni siya kuba phezulu kakhulu, sibangele ukunxitywa kwesixhobo esibukhali.
"Ubushushu" "ngumoni" we-titanium alloy ekunzima ukuyiqhuba!
2. Iingcebiso zenkqubo yokucubungula i-titanium alloy
Kwisiseko sokuqonda indlela yokucutshungulwa kwe-titanium alloy, idityaniswe namava angaphambili, olona lwazi luphambili lwetekhnoloji yokusetyenzwa kwe-titanium alloy lulolu hlobo lulandelayo:
(1) I-blade enejiyometri ye-engile evumayo isetyenziselwa ukunciphisa amandla okusika, ukusika ubushushu kunye nokuguqulwa komsebenzi.
(2) Gcina ukondla okuzinzileyo ukuze ugweme ukuqina kwendawo yokusebenza.Isixhobo siya kuhlala sikwimeko yokutya ngexesha lokusika.Ixabiso le-radial cut ae ngexesha lokusila liya kuba yi-30% yeradiyasi.
(3) Uxinzelelo oluphezulu kunye nokuhamba okukhulu kwamanzi okusika kusetyenziselwa ukuqinisekisa ukuzinza kwe-thermal yenkqubo yomatshini, kwaye ugweme ukuwohloka komphezulu we-workpiece kunye nomonakalo wesixhobo ngenxa yokushisa okugqithisileyo.
(4) Gcina incakuba ibukhali.Isixhobo esingenabuthuntu yimbangela yokuqokelela ubushushu kunye nokunxiba, okukhokelela nje ekungaphumeleli kwesixhobo.
(5) Kangangoko kunokwenzeka, kufuneka kusetyenzwe kwimo ethambileyo ye-titanium alloy.Njengoko izinto ziba nzima ngakumbi ukucubungula emva kokuqina, unyango lokushisa luphucula amandla ezinto eziphathekayo kwaye lwandise ukunxiba kwe-blade.
(6) Sebenzisa isixhobo esikhulu se-arc radius okanye i-chamfer ukusika, kwaye ubeke iincakuba ezininzi kwindawo yokusika kangangoko.Oku kunokunciphisa amandla okusika kunye nokushisa kwinqanaba ngalinye kwaye ugweme umonakalo wendawo.Xa ukugaya i-titanium alloy, isantya sokusika sinempembelelo enkulu kwisixhobo sobomi vc, kulandelwa ukusika kwe-radial (ubunzulu bokugaya) ae.
3. Ukusingatha iingxaki zokulungisa i-titanium ukusuka kwincakuba
Ukunxitywa kwe-groove ye-blade ngexesha lokucutshungulwa kwe-titanium alloy kukunxitywa kwendawo yangasemva kunye nangaphambili ecaleni kobunzulu bokusika, okuhlala kubangelwa ngumaleko oqinileyo oshiywe kukusetyenzwa kwangaphambili.Ukusabela kweekhemikhali kunye nokusasazwa kwesixhobo kunye nezinto zokusebenza kwiqondo lokushisa elingaphezulu kwe-800 ℃ sesinye sezizathu zokuyilwa kokunxiba kwegroove.Njengoko iimolekyuli ze-titanium ze-workpiece ziqokelela phambi kwe-blade ngexesha lokucubungula, "zidibene" kwi-blade phantsi koxinzelelo oluphezulu kunye nobushushu obuphezulu, zenza i-tumor buildup tumor.Xa i-chip eyakhiweyo ihlanjululwe kwi-blade, i-carbide coating ye-cemented ye-blade iyasuswa.Ngoko ke, ukusetyenzwa kwe-titanium alloy kufuna izinto ezikhethekileyo ze-blade kunye nemilo yejometri.
