Kutheni sicinga ukuba i-titanium alloy yinto enzima ukuyenza kumatshini? Ngenxa yokungabikho kokuqonda okunzulu kwendlela yokucubungula kunye nesiganeko.
1. I-Physical Phenomena ye-Titanium Machining
Amandla okusika we-titanium alloy processing angaphezulu kancinane kunentsimbi enobunzima obufanayo, kodwa isenzeko somzimba sokusetyenzwa kwe-titanium alloy sintsonkothile kakhulu kunoko kusetyenzwa kwentsimbi, okwenza 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. Ke ngoko, ubushushu obuveliswe kwinkqubo yokusika i-titanium alloy abuyi kudluliselwa ngokukhawuleza kwi-workpiece okanye ithathwe ziitshiphusi, kodwa buya kuqokelelwa kwindawo yokusika, kwaye ubushushu obuveliswayo bunokufikelela kwi-1000 ° C, kubangele ukusika isixhobo sokunxiba, ukuqhekeka kunye nokufa ngokukhawuleza. Ukwakhiwa komphetho wokwakha, ukubonakala okukhawulezileyo kwemiphetho egugileyo, kuvelisa ubushushu obuninzi kwindawo yokusika, bufutshane ngakumbi ubomi besixhobo.
Ubushushu obuphezulu obuveliswe ngexesha lenkqubo yokusika kwakhona buyatshabalalisa ingqibelelo yendawo ye-titanium alloy parts, okubangela ukuncipha kokuchaneka kwejometri yenxalenye kunye nomsebenzi onzima owenzela ukunciphisa amandla ayo okukhathala.
I-elasticity ye-titanium alloys inokuba luncedo ekusebenzeni kwenxalenye, kodwa ngexesha lokusika, i-deformation elastic ye-workpiece yimbangela ebalulekileyo yokungcangcazela. Uxinzelelo lokusika lubangela ukuba i-workpiece "elastic" ishiye isixhobo kunye ne-rebound, ukwenzela ukuba ingxabano phakathi kwesixhobo kunye ne-workpiece inkulu kunesenzo sokusika. Inkqubo yokukhuhlana iphinda ivelise ubushushu, nto leyo eyenza ibe mandundu ngakumbi ingxaki yokungahambi kakuhle kwe-thermal ye-titanium alloys.
Le ngxaki inobuzaza ngakumbi xa kusetyenzwa iindawo ezinodonga olucekethekileyo okanye ezimise okweringi ezigogeke ngokulula. Ayingomsebenzi ulula ukusetyenzwa kwe-titanium alloy ezinodonga olucekeceke iindawo ezilindelekileyo zokuchaneka komlinganiselo. Ngenxa yokuba xa izinto zokusebenza zityhalwa kude ngesixhobo, i-deformation yendawo yodonga olubhityileyo igqithise uluhlu lwe-elastic ukuvelisa i-deformation yeplastiki, kwaye amandla ezinto eziphathekayo kunye nobunzima kwindawo yokusika yanda kakhulu. Ngeli xesha, i-machining kwisantya esinqunyiwe sokuqala siphezulu kakhulu, nto leyo ekhokelela ekunxibeleni okubukhali kwesixhobo.
"Ukushisa" "ngunobangela" wobunzima bokucubungula i-titanium alloys!
2. Ulwazi lwetekhnoloji yokusetyenzwa kwe-titanium alloys
Kwisiseko sokuqonda indlela yokucutshungulwa kwe-titanium alloys, edityaniswa namava adlulileyo, eyona nkqubo iphambili yokwazi indlela yokucubungula i-titanium alloys yile ilandelayo:
(1) Ukufakwa nge-engile yejiyometri elungileyo ukunciphisa amandla okusika, ukusika ubushushu kunye ne-deformation ye-workpiece.
(2) Gcina ukondla rhoqo ukuphepha ukuqina kwesixhobo sokusebenza. Isixhobo kufuneka sihlale sikwimeko yokutya ngexesha lokusika. Ixabiso le-radial cut ae kufuneka libe yi-30% yeradiyasi ngexesha lokusila.
(3) I-high-pressure kunye ne-flow flowing cutting cutting fluid isetyenziselwa ukuqinisekisa ukuzinza kwe-thermal ye-machining process kunye nokuthintela umphezulu we-workpiece ukusuka ekuwohlokeni kunye nomonakalo wesixhobo ngenxa yokushisa okugqithisileyo.
(4) Gcina umgca wokusika we-blade ubukhali, iimela ezinqabileyo ziyimbangela yokwakhiwa kobushushu kunye nokuguga, okunokubangela ukuba kube lula ukusilela kweemela.
(5) Ukucubungula kwi-softest state ye-titanium alloy ngokusemandleni, ngenxa yokuba izinto ziba nzima ukuqhutyelwa emva kokuqina, unyango lobushushu luphucula amandla ezinto eziphathekayo kwaye lwandise ukunxiba kwe-blade.
(6) Sebenzisa i-radius yempumlo enkulu okanye i-chamfer ukusika kangangoko kunokwenzeka kwi-edge yokusika. Oku kunokunciphisa amandla okusika kunye nokushisa kwinqanaba ngalinye kwaye kuthintele ukuphuka kwendawo. Xa ukugaya i-titanium alloys, phakathi kweeparitha zokusika, isantya sokusika sinempembelelo enkulu kwisixhobo sobomi vc, silandelwa yi-radial cutting amount (ubunzulu bokugaya) ae.

3. Ukusombulula iingxaki zokusetyenzwa kwe-titanium ukusuka kwincakuba
Ukunxitywa kwe-blade groove okwenzeka ngexesha lokulungiswa kwe-titanium alloy kukunxitywa kwendawo yangasemva nangaphambili ecaleni kobunzulu becala elisikiweyo, elihlala libangelwa ngumaleko oqinileyo oshiywe kukusetyenzwa kwangaphambili. Ukusabela kweekhemikhali kunye nokusabalalisa phakathi kwesixhobo kunye nezixhobo zokusebenza kwiqondo lokushisa elingaphezulu kwe-800 ° C sesinye sezizathu zokubunjwa kwe-groove wear. Ngenxa yokuba ngexesha lokucutshungulwa, iimolekyuli ze-titanium ze-workpiece ziqokelela phambi kwe-blade, kwaye "zifakwe kwi-welded" kwi-blade phantsi koxinzelelo oluphezulu kunye nokushisa okuphezulu, ukwenza i-edge eyakhelweyo. Xa i-edge eyakhelweyo ikhupha i-peel kude ne-cut cut, ithatha i-carbide coating of the insert, ngoko ke i-titanium machining ifuna izinto ezikhethekileyo zokufaka kunye neejometri.
4. Ulwakhiwo lwesixhobo esifanelekileyo kwi-titanium machining
Ingqwalasela ye-titanium alloy processing bubushushu. Umthamo omkhulu we-high-pressure cutting fluid kufuneka utshizwe kwi-cut cut edge ngexesha elifanelekileyo kwaye uchanekileyo ukususa ukushisa ngokukhawuleza. Kukho ulwakhiwo olulodwa lwabasiki bokungqusha abasetyenziselwa ngokukodwa ukusetyenzwa kwe-titanium alloy kwimarike.
