Kutheni le nto i-titanium alloy iyinto enzima ukwenza umatshini?

1. Iziganeko ezibonakalayo ze-titanium machining

Amandla okusika we-titanium alloy processing angaphezulu kancinci kunentsimbi enobunzima obufanayo, kodwa into ebonakalayo yokusetyenzwa kwe-titanium alloy inzima kakhulu kuneyokusetyenzwa 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 alloys ayiyi kudluliselwa ngokukhawuleza kwi-workpiece okanye ithathwe yi-chips, kodwa iya kuqokelela kwindawo yokusika, kwaye ubushushu obuveliswayo bunokuphakama njenge-1 000 ° C okanye ngaphezulu. , okuya kubangela ukuba umgca wokusika wesixhobo ugqoke ngokukhawuleza, udibanise kunye nokuqhekeka. Ukuqulunqwa komgca owenziweyo, ukubonakala ngokukhawuleza komgca ogugileyo, ukuvelisa ubushushu obuninzi kwindawo yokusika, kunciphise ngakumbi ubomi besixhobo.ukwenziwa kwe-titanium

Amaqondo okushisa aphezulu avelisiweyo ngexesha lenkqubo yokusika aphinde atshabalalise ingqibelelo yendawo ye-titanium alloy parts, okubangela ukuncipha kokuchaneka kwejometri yamacandelo kunye nomsebenzi onzima onciphisa kakhulu amandla abo 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" ihambe kude nesixhobo kwaye ibhobhoze ukwenzela ukuba ingxabano phakathi kwesixhobo kunye ne-workpiece inkulu kunesenzo sokusika. Inkqubo yokukhuhlana iphinda ivelise ubushushu, nto leyo eyenza kube mandundu ngakumbi ingxaki yokungahambi kakuhle kwe-thermal ye-titanium alloys.

Le ngxaki inzima ngakumbi xa kusenziwa izixhobo ezinodonga olucekethekileyo okanye ezimise okweringi ezikhubazeka ngokulula. Ayingomsebenzi olula ukutshiza iindawo zengxubevange yetitanium ezinodonga olucekethekileyo ukuya kokuchaneka okulindelweyo. Ngenxa yokuba xa izinto zokusebenza zityhalwa kude ngesixhobo, i-deformation yendawo yodonga oluncinci lugqithise uluhlu lwe-elastic kunye ne-deformation yeplastiki eyenzekayo, kwaye amandla ezinto eziphathekayo kunye nobunzima bendawo yokusika kwanda kakhulu. Ngeli xesha, ukwenza oomatshini ngesantya esimiselweyo sokusika kuba phezulu kakhulu, nto leyo ekhokelela ekunxityweni kwesixhobo esibukhali.

"Kushushu" "ngumoni" ekunzima ukusetyenzwa ngayo ialloys zetitanium!

2. Ulwazi lwetekhnoloji yetitanium cnc machining

Kwisiseko sokuqonda indlela yokucutshungulwa kwe-titanium alloys kunye nokongeza amava adlulileyo, eyona nkqubo iphambili yokwazi indlela yokucubungula i-titanium alloys yile ilandelayo:

(1) Ukufakwa nge-geometry efanelekileyo kusetyenziselwa ukunciphisa amandla okusika, ukusika ubushushu kunye nokuguqulwa kwendawo yokusebenza.

(2) Gcina isondlo rhoqo ukuze ugweme ukuqina kwe-workpiece. Isixhobo kufuneka sihlale sikwimeko yokutya ngexesha lenkqubo yokusika, kunye nexabiso lokusika i-radial kufuneka libe yi-30% ye-radius ngexesha lokugaya.

(3) I-high-pressure kunye ne-flow flowing cutting cutting fluid isetyenziselwa ukuqinisekisa ukuzinza kwe-thermal ye-machining process kunye nokuthintela ukuchithwa kwendawo yokusebenza kunye nomonakalo wesixhobo ngenxa yokushisa okugqithisileyo.

(4) Gcina i-blade edge ibukhali, izixhobo ezibuthuntu zingunobangela wokwakhiwa kobushushu kunye nokuguga, okunokuthi kukhokelela ngokulula kwisixhobo.

(5) Ukucoca kwimeko ethambileyo ye-titanium alloy kangangoko kunokwenzeka, kuba izinto ziba nzima kakhulu kumatshini emva kokuqina, kunye nonyango lobushushu kwandisa amandla ezinto kunye nokwandisa ukunxiba kokufakwa.

(6) Sebenzisa i-radius yempumlo enkulu okanye i-chamfer ukusika kangangoko kunokwenzeka kwi-edge yokusika. Oku kunciphisa amandla okusika kunye nobushushu kwindawo nganye kwaye kuthintela ukuphuka kwendawo. Xa i-alloys ye-titanium yokugaya, phakathi kweeparitha zokusika, isantya sokusika sinempembelelo enkulu kwisixhobo sobomi vc, silandelwa yi-radial engagement (ubunzulu bokugaya) ae.

3. Qala nge-blade ukusombulula ingxaki ye-titanium processing

Ukunxitywa kwe-groove yokufaka ngexesha lokulungiswa kwee-alloys ze-titanium kukunxitywa kwendawo yangasemva nangaphambili kwicala lobunzulu bokusikwa, okuhlala kubangelwa ngumaleko olukhuni oshiywe yinkqubo yangaphambili. Ukusabela kweekhemikhali kunye nokusasazwa kwesixhobo kunye nezixhobo zokusebenza kwiqondo lokushisa elingaphezulu kwe-800 °C sesinye sezizathu zokubunjwa kwe-groove ukunxiba. Ngenxa yokuba ngexesha lenkqubo yomatshini, iimolekyuli ze-titanium ze-workpiece ziqokelela phambi kwe-blade kwaye "zifakwe kwi-welded" kwi-blade edge phantsi koxinzelelo oluphezulu kunye nobushushu obuphezulu, zenza umda owenziweyo. Xa i-edge eyakhelweyo ikhupha umgca wokusika, ithatha i-carbide coating of the insert, ngoko ke i-titanium machining ifuna izinto ezikhethekileyo zokufaka kunye neejometri.ukuchaneka ngokwesiko komatshini

4. Ulwakhiwo lwesixhobo esifanelekileyo kwi-titanium machining

Ugxininiso lwe-titanium alloy processing lubushushu, kwaye inani elikhulu le-high-pressure cutting fluid kufuneka litshizwe kwi-cut cut edge ngexesha elifanelekileyo kwaye lichanekileyo ukususa ngokukhawuleza ukushisa. Kukho ulungelelwaniso olulodwa lwabasiki be-milling kwimarike ngokukodwa ukwenza i-titanium.
