Chifukwa chiyani tikuganiza kuti titaniyamu aloyi ndizovuta kupanga makina? Chifukwa chosowa kumvetsetsa mozama za njira yake yopangira zinthu komanso zochitika zake.
1. Zochitika Zathupi za Titanium Machining
Mphamvu yodula ya titaniyamu aloyi processing ndi apamwamba pang'ono kuposa chitsulo ndi kuuma chomwecho, koma chodabwitsa thupi processing titaniyamu aloyi ndi zovuta kwambiri kuposa processing zitsulo, zomwe zimapangitsa titaniyamu aloyi processing kukumana ndi mavuto aakulu.
Kutentha kwa ma alloys ambiri a titaniyamu ndi otsika kwambiri, 1/7 yokha yachitsulo ndi 1/16 ya aluminiyamu. Choncho, kutentha kwaiye m`kati kudula titaniyamu aloyi sadzakhala mwamsanga anasamutsidwa workpiece kapena kuchotsedwa ndi tchipisi, koma anasonkhana m'dera kudula, ndi kutentha kwaiye kungakhale mkulu monga 1000 ° C, kuchititsa kudula chida kuvala, kusweka ndi kufa mofulumira. Kumangirira m'mphepete, mawonekedwe othamanga a m'mphepete mwake, komwe kumapangitsa kutentha kwambiri m'dera lodulira, kufupikitsa moyo wa zida.
The mkulu kutentha kwaiye pa ndondomeko kudula komanso kuwononga pamwamba umphumphu wa titaniyamu aloyi mbali, chifukwa mu kuchepa kwa geometric lolondola mbali ndi ntchito kuumitsa chodabwitsa kuti kwambiri amachepetsa kutopa mphamvu.
Kukhazikika kwa titaniyamu aloyi kumatha kukhala kopindulitsa pakuchita pang'ono, koma panthawi yodula, kusinthika kwa zotanuka kwa chogwirira ntchito ndikofunikira kwambiri pakugwedezeka. Kupanikizika kodula kumapangitsa kuti "elastic" workpiece ichoke pa chida ndikubwezeretsanso, kotero kuti kukangana pakati pa chida ndi workpiece kumakhala kwakukulu kuposa kudula. Kukanganako kumapangitsanso kutentha, zomwe zimakulitsa vuto la kusayenda bwino kwa matenthedwe a titaniyamu.
Vutoli ndi lalikulu kwambiri mukakonza zigawo zopyapyala kapena zooneka ngati mphete zomwe zimapunduka mosavuta. Sichinthu chophweka kukonza titaniyamu aloyi zopyapyala zokhala ndi mipanda yoyembekezeka yolondola. Chifukwa pamene zida zogwirira ntchito zimakankhidwira kutali ndi chida, mapindikidwe am'deralo a khoma lopyapyala amatha kupitirira zotanuka kuti apange mapindikidwe a pulasitiki, ndipo mphamvu zakuthupi ndi kuuma pamalo odulira kumawonjezeka kwambiri. Panthawiyi, makinawo pa liwiro lodziwika bwino lodulidwa amakhala okwera kwambiri, zomwe zimapangitsa kuti chidacho chiwonongeke.
"Kutentha" ndi "cholakwa" chazovuta za kukonza titaniyamu alloys!
2. Kudziwa luso laukadaulo pokonza ma aloyi a titaniyamu
Pamaziko a kumvetsetsa njira yopangira ma aloyi a titaniyamu, kuphatikiza ndi zomwe zidachitika kale, njira yayikulu yodziwira ma aloyi a titaniyamu ndi motere:
(1) Amayika ndi geometry yowoneka bwino kuti muchepetse mphamvu yodulira, kudula kutentha ndi kusinthika kwa workpiece.
(2) Sungani chakudya chokhazikika kuti mupewe kuuma kwa workpiece. Chidacho chiyenera kukhala nthawi zonse mu chakudya panthawi yodula. Kudula kwa radial ae kuyenera kukhala 30% ya utali wozungulira panthawi yopera.
(3) Kuthamanga kwambiri komanso kuthamanga kwakukulu kwamadzimadzi kumagwiritsidwa ntchito pofuna kutsimikizira kukhazikika kwa kutentha kwa makina opangira makina komanso kuteteza malo ogwirira ntchito kuti asawonongeke ndi kuwonongeka kwa zida chifukwa cha kutentha kwakukulu.
(4) Sungani m'mphepete mwa mpeni wakuthwa, mipeni yosamveka ndiyomwe imayambitsa kutentha ndi kuvala, zomwe zingayambitse kulephera kwa mipeni.
(5) Kukonzekera mumtundu wofewa kwambiri wa titaniyamu momwe zingathere, chifukwa zinthuzo zimakhala zovuta kuzikonza pambuyo poumitsa, chithandizo cha kutentha chimapangitsa mphamvu ya zinthuzo ndikuwonjezera kuvala kwa tsamba.
(6) Gwiritsani ntchito mphuno yaikulu yozungulira kapena chamfer kuti mudule momwe mungathere m'mphepete. Izi zitha kuchepetsa mphamvu yodulira ndi kutentha pamalo aliwonse ndikuletsa kusweka kwanuko. Pamene mphero titaniyamu aloyi, pakati pa magawo kudula, liwiro kudula ali ndi chikoka chachikulu pa moyo chida vc, kutsatiridwa ndi ma radial kudula kuchuluka (mphero kuya) ae.
Zida za Xinfa CNC zili ndi mawonekedwe abwino komanso otsika mtengo. Kuti mudziwe zambiri, chonde pitani:

3. Kuthetsa mavuto a titaniyamu kuyambira pa tsamba
Kuvala kwa blade groove komwe kumachitika pakupanga titaniyamu alloy ndi kuvala kwanuko kumbuyo ndi kutsogolo motsatira kuya kwa mbali yodulidwa, yomwe nthawi zambiri imayamba chifukwa cha kusanjikiza kowumitsidwa komwe kumasiyidwa ndi kukonza koyambirira. Zomwe zimapangidwira komanso kufalikira pakati pa chida ndi zinthu zogwirira ntchito pa kutentha kwapamwamba kuposa 800 ° C ndi chimodzi mwa zifukwa zomwe zimapangidwira kuvala kwa groove. Chifukwa panthawi yokonza, mamolekyu a titaniyamu a workpiece amadziunjikira kutsogolo kwa tsamba, ndipo "amawotcherera" ku tsamba pansi pa kupanikizika kwakukulu ndi kutentha kwakukulu, kupanga m'mphepete mwake. Pamene anamanga m'mphepete peels kutali m'mphepete kudula, amachotsa ❖ kuyanika carbide wa Ikani, kotero machining titaniyamu kumafuna zipangizo Ikani ndi geometries.
4. Kapangidwe kachipangizo koyenera kupanga titaniyamu
Cholinga cha titaniyamu alloy processing ndi kutentha. Kuchulukirachulukira kwamadzimadzi odulira mwamphamvu kwambiri kumayenera kupopera pamphepete mwanthawi yake komanso molondola kuti muchotse kutentha mwachangu. Pali mawonekedwe apadera a odula mphero omwe amagwiritsidwa ntchito makamaka pokonza titaniyamu alloy pamsika.
