Pambuyo pazaka zambiri zopanga makina, mumadziwa mphero ya trochoidal

Kodi Trochoidal Milling ndi chiyani

Makina omaliza amagwiritsidwa ntchito kwambiri popanga ndege, ma grooves ndi malo ovuta. Mosiyana ndi kutembenuka, pokonza grooves ndi malo ovuta a zigawozi, njira yopangira njira ndi kusankha mphero ndizofunikira kwambiri. Monga njira yamba yopangira mphero, ma arc contact angle of the same processing processing amatha kufika pa 180 °, kutentha kwa mpweya kumakhala koipa, ndipo kutentha kumakwera kwambiri panthawi yokonza. Komabe, ngati njira yodulira yasinthidwa kuti wodula mphero azungulire mbali imodzi ndikuzungulira mbali inayo, kukhudza ngodya ndi kuchuluka kwa kudula pakusintha kumachepetsedwa, mphamvu yodulira ndi kudula kutentha kumachepetsedwa, ndipo moyo wa chida umatalikirapo. . Chifukwa chake, kudula kumatha kupitilira kwa nthawi yayitali, monga (Chithunzi 1) kumatchedwa trochoidal milling.

Ubwino wake ndikuti umachepetsa zovuta za kudula ndikuonetsetsa kuti ntchitoyo ndi yabwino. Kusankha koyenera kwa magawo odulira kumatha kuwongolera bwino ndikuchepetsa ndalama, makamaka pokonza zinthu zovuta ku makina monga ma aloyi osagwira kutentha ndi zinthu zolimba kwambiri, zimatha kuchita nawo gawo lake kwambiri, ndipo Zili ndi kuthekera kwakukulu kwachitukuko, komwe kungakhale chifukwa chimene makampani amapereka chidwi kwambiri ndi kusankha trochoidal mphero njira.

Ubwino waukadaulo

Cycloid imatchedwanso trochoid ndi epicycloid yowonjezera, ndiko kuti, njira ya mfundo kunja kapena mkati mwa bwalo losuntha pamene bwalo losuntha limatulutsa mzere wina wowongoka kuti ugubuduze popanda kutsetsereka. Itha kutchedwanso cycloid yayitali (yaufupi). Kukonzekera kwa Trochoidal ndiko kugwiritsa ntchito mphero yokhala ndi m'mimba mwake yaying'ono kuposa m'lifupi mwa poyambira kupanga poyambira theka la arc kukhala gawo laling'ono la arc kumbali yake. Imatha kukonza ma grooves osiyanasiyana komanso ma cavities apamwamba. Mwanjira iyi, mwamalingaliro, mphero imatha kukonza ma grooves ndi mbiri yamtundu uliwonse wokulirapo kuposa iyo, ndipo imathanso kukonza zinthu zingapo mosavuta.

Ndi chitukuko ndi kugwiritsa ntchito ukadaulo wowongolera manambala apakompyuta, njira yowongolera mphero, kukhathamiritsa kwa magawo odulira, komanso kuthekera kosiyanasiyana kwa mphero ya trochoidal ikugwiritsidwa ntchito ndikubweretsedwa mochulukirapo. Ndipo idaganiziridwa ndikuyamikiridwa ndi mafakitale opanga magawo monga zakuthambo, zida zoyendera ndi zida komanso kupanga nkhungu. Makamaka muzamlengalenga, aloyi wa titaniyamu omwe amagwiritsidwa ntchito kwambiri ndi zida za nickel-based alloy-resistant alloy zimakhala ndi zovuta zama makina, kuphatikiza:

Kutentha kwakukulu kwamphamvu ndi kuuma kumapangitsa kuti zikhale zovuta kuti chida chodulira chinyamule kapena ngakhale kupunduka;

Kumeta ubweya wambiri kumapangitsa kuti tsambalo likhale losavuta kuwonongeka;

Kutsika kwamafuta otsika kumapangitsa kuti zikhale zovuta kuti kutentha kwakukulu kutumizidwe kumalo odulirako, komwe kutentha kumapitilira 1000ºC, zomwe zimakulitsa kuvala kwa zida;

Pa processing, zinthu zambiri welded kwa tsamba, chifukwa anamanga m'mphepete. Osauka makina pamwamba khalidwe;

Ntchito kuumitsa chodabwitsa cha faifi tambala zochokera kutentha zosagwira aloyi zipangizo ndi austenite masanjidwewo ndi aakulu;

Ma carbides mu microstructure ya nickel-based alloys osatentha kutentha amapangitsa kuti chidacho chiwonongeke;

Mafuta a titaniyamu amakhala ndi zochita zambiri zamakina, ndipo machitidwe amankhwala amathanso kukulitsa kuwonongeka ndi zina zotero.

Mavutowa amatha kukonzedwa mosalekeza komanso bwino mothandizidwa ndi ukadaulo wa trochoidal milling.

Chifukwa cha kukhathamiritsa kosalekeza kwa zida za zida, zokutira, mawonekedwe a geometric, ndi kapangidwe kake, kupita patsogolo mwachangu kwa machitidwe anzeru owongolera, matekinoloje apulogalamu, ndi zida zamakina othamanga kwambiri, othamanga kwambiri, othamanga kwambiri (HSC) komanso kuchita bwino kwambiri. (HPC) kudula kwafikanso pamlingo. utali watsopano. High-liwiro Machining makamaka amaona kusintha liwiro. Mkulu-mwachangu Machining sayenera kuganizira kusintha liwiro kudula, komanso kuganizira kuchepetsa nthawi wothandiza, rationally sintha magawo osiyanasiyana kudula ndi kudula njira, ndi kuchita pawiri Machining kuchepetsa njira, kusintha zitsulo kuchotsa mlingo pa unit nthawi, ndi nthawi yomweyo onjezerani moyo wa chida ndikuchepetsa Mtengo, lingalirani zachitetezo cha chilengedwe.

chiyembekezo chaukadaulo

Malinga ndi deta ntchito trochoidal mphero mu aero-injini (monga taonera m'munsimu), pokonza titaniyamu aloyi Ti6242, mtengo wa kudula zida pa buku buku akhoza kuchepetsedwa pafupifupi 50%. Maola a anthu amatha kuchepetsedwa ndi 63%, kufunikira kwa zida zonse kumatha kuchepetsedwa ndi 72%, ndipo mtengo wa zida ukhoza kuchepetsedwa ndi 61%. Maola ogwiritsira ntchito X17CrNi16-2 amatha kuchepetsedwa ndi 70%. Chifukwa cha zokumana nazo zabwinozi ndi zopambana, njira yotsogola ya mphero ya trochoidal yagwiritsidwa ntchito m'minda yambiri, ndipo yalandiranso chidwi ndikuyamba kugwiritsidwa ntchito m'magawo ena a micro-precision Machining.
