Kungani i-titanium alloy iyinto enzima ukuyenza?

1. Izigigaba ezibonakalayo zemishini ye-titanium

Amandla okusika okucubungula i-titanium alloy aphakeme kancane kunensimbi enobunzima obufanayo, kodwa isimo somzimba sokucubungula i-titanium alloy siyinkimbinkimbi kakhulu kunaleyo yokucubungula insimbi, okwenza ukucubungula kwe-titanium alloy kubhekane nobunzima obukhulu.

I-thermal conductivity yama-alloys amaningi e-titanium iphansi kakhulu, i-1/7 kuphela yensimbi kanye ne-1/16 ye-aluminium. Ngakho-ke, ukushisa okukhiqizwa ngesikhathi sokusika ama-alloys e-titanium ngeke kudluliselwe ngokushesha ku-workpiece noma kuthathwe ama-chips, kodwa kuzoqoqa endaweni yokusika, futhi izinga lokushisa elikhiqizwayo lingaba phezulu ku-1 000 ° C noma ngaphezulu. , okuzokwenza ukuthi umkhawulo wokusika wethuluzi ugqoke ngokushesha, uhlakaze futhi uqhekeke. Ukwakheka konqenqema olwakhiwe, ukubukeka okusheshayo konqenqema olugugile, nakho kukhiqiza ukushisa okwengeziwe endaweni yokusika, kunciphise ngokwengeziwe impilo yethuluzi.umshini we-titanium

Amazinga okushisa aphezulu akhiqizwa phakathi nenqubo yokusika aphinde abhubhise ubuqotho obungaphezulu bezingxenye ze-titanium alloy, okuholela ekwehleni kokunemba kwejometri yezingxenye kanye nokusebenza kanzima okunciphisa kakhulu amandla abo okukhathala.

I-elasticity ye-titanium alloys ingase ibe nenzuzo ekusebenzeni kwengxenye, kodwa ngesikhathi sokusika, ukuguqulwa kwe-elastic kwe-workpiece kuyimbangela ebalulekile yokudlidliza. Ingcindezi yokusika idala ukuthi i-workpiece "elastic" isuke kude nethuluzi bese igxuma ukuze ukungqubuzana phakathi kwethuluzi nomsebenzi kube kukhulu kunesenzo sokusika. Inqubo yokungqubuzana iphinde ikhiqize ukushisa, ibhebhethekise inkinga yokungaphatheki kahle kokushisa kwezingxube ze-titanium.

Le nkinga ibucayi nakakhulu lapho kwenziwa izingxenye ezinezindonga ezincane noma eziyindandatho ezigogeke kalula. Akuwona umsebenzi olula ukufaka izingxenye zengxube ye-titanium enezindonga ezincane zibe nokunemba kobukhulu obulindelwe. Ngoba lapho i-workpiece material ixoshwa yithuluzi, ukuguqulwa kwendawo yodonga oluncane kudlule uhla olunwebekayo kanye nokuguqulwa kwepulasitiki kwenzeka, futhi amandla wezinto ezibonakalayo nobulukhuni bephoyinti lokusika kukhula kakhulu. Kuleli qophelo, ukwenza imishini ngesivinini esinqunyiwe ngaphambili sokusika kuba phezulu kakhulu, okuholela ekugugeni kwamathuluzi abukhali.

"Hot" "yicala" okunzima ukucubungula ama-alloys e-titanium!

2. Ulwazi lwezobuchwepheshe lwetitanium cnc machining

Ngokwesisekelo sokuqonda indlela yokucubungula ye-titanium alloys kanye nokwengeza isipiliyoni esidlule, ulwazi lwenqubo eyinhloko yokucubungula ama-alloys e-titanium lumi kanje:

(1) Ukufakwa okunejiyomethri eqondile kusetshenziselwa ukunciphisa amandla okusika, ukusika ukushisa kanye nokuguqulwa kwe-workpiece.

(2) Gcina okuphakelayo njalo ukuze ugweme ukuqina kwe-workpiece. Ithuluzi kufanele lihlale lisesimweni sokuphakelwa ngesikhathi sokusika, futhi inani lokusika i-radial ae kufanele libe ngu-30% werediyasi ngesikhathi sokugaya.

(3) Uketshezi lokusika olunomfutho ophezulu kanye nokugeleza okukhulu lusetshenziselwa ukuqinisekisa ukuzinza okushisayo kwenqubo yomshini futhi kuvimbele ukuwohloka kwendawo yokusebenzela kanye nokulimala kwamathuluzi ngenxa yokushisa ngokweqile.

(4) Gcina unqenqema lwe-blade lubukhali, amathuluzi abuthuntu ayimbangela yokwakheka kokushisa nokuguga, okungaholela kalula ekuhlulekeni kwamathuluzi.

(5) Ukucutshungulwa esimweni esithambile kakhulu se-titanium alloy ngangokunokwenzeka, ngoba impahla iba nzima kakhulu umshini ngemva kokuqina, futhi ukwelashwa kokushisa kwandisa amandla wento futhi kwandisa ukuguga kokufakwayo.

(6) Sebenzisa indawo enkulu yekhala noma i-chamfer ukusika ngangokunokwenzeka onqenqemeni lokusika. Lokhu kunciphisa amandla okusika nokushisa kuzo zonke izindawo futhi kuvimbela ukuphuka kwendawo. Lapho kugaywa ama-alloys e-titanium, phakathi kwemingcele yokusika, isivinini sokusika sinethonya elikhulu empilweni yamathuluzi vc, okulandelwa ukubandakanyeka kwe-radial (ukujula kokugaya) ae.

3. Qala nge-blade ukuxazulula inkinga yokucubungula i-titanium

Ukuguga kwe-groove yokufaka phakathi nomshini wama-alloys e-titanium ukuguga kwendawo ngemuva nangaphambili kubheke ekujuleni kokusikwa, okuvame ukubangelwa ungqimba oluqinile olushiywe ukucutshungulwa kwangaphambilini. Ukusabela kwamakhemikhali kanye nokusabalalisa kwethuluzi kanye nezinto zokusebenza endaweni yokushisa yokucubungula engaphezu kuka-800 °C nakho kungesinye sezizathu zokwakheka kokugqoka kwe-groove. Ngoba ngesikhathi senqubo yomshini, ama-molecule e-titanium we-workpiece aqoqana phambi kwe-blade futhi "ahlanganiswe" emaphethelweni e-blade ngaphansi kwengcindezi ephakeme kanye nokushisa okuphezulu, okwenza unqenqema olwakhiwe. Lapho unqenqema olwakhiwe lucweba onqenqemeni lokusika, lususa uqweqwe lwe-carbide lokufaka, ngakho-ke umshini we-titanium udinga izinto zokufaka ezikhethekile kanye namajiometri.ukunemba ngokwezifiso machining

4. Isakhiwo sethuluzi esilungele ukwenziwa kwe-titanium machining

Ukugxila ekucubunguleni i-titanium alloy ukushisa, futhi inani elikhulu le-high-pressure cutting fluid kufanele lifafazwe onqenqemeni lokusika ngesikhathi nangendlela enembile ukuze kukhishwe ukushisa ngokushesha. Kukhona ukucushwa okuhlukile kwabasiki be-milling emakethe ikakhulukazi ukwenza imishini ye-titanium.
