M'zaka zaposachedwa, zida zodulira za PCD zakhala zikugwiritsidwa ntchito kwambiri m'mafakitale opangira aluminiyamu, zotayira zotayidwa, zamkuwa, ndi zida zina zopanda zitsulo.
Kodi ubwino wa zida za PCD zodulira mu aluminiyamu ndi momwe mungasankhire zida zoyenera zodulira PCD?
Ndi chiyaniZida zodulira PCD?
Zida zodulira PCD nthawi zambiri zimatanthawuza zida za diamondi za polycrystalline.The PCD gulu pepala ntchito sintered kuchokera zachilengedwe kapena artificially synthesized diamondi ufa ndi zomangira (zokhala zitsulo monga cobalt ndi faifi tambala) mu gawo lina pa kutentha (1000-2000 ℃) ndi kuthamanga kwambiri (50000 kuti 100000 atmospheres).Sikuti imakhala ndi kuuma kwakukulu komanso kukana kwa PCD, komanso imakhala ndi mphamvu zabwino komanso kulimba kwa carbide.
Ikasinthidwa kukhala chida chodulira, imakhala ndi mawonekedwe a kuuma kwambiri, kukhathamiritsa kwamafuta ambiri, kutsika kwamafuta owonjezera, modulus yotanuka kwambiri, komanso kugundana kocheperako.
Zida zodulira za OPT ndizogulitsa zapamwamba kwambiri za PCD, Timakuthandizani pakugula zomwe mukufuna pachaka pamitengo yopikisana, popereka ntchito zapamwamba komanso ntchito zambiri.
Ubwino wa PCD Ikani mu aluminium processing
(1) Kuuma kwa zida za PCD kumatha kufikira 8000HV (nthawi 80-120 kuposa ya carbides)
ndipo kukana kwawo kuvala ndikwabwino kwambiri.
(2) Thermal conductivity ya zida za PCD ndi 700W/MK (1.5-9 nthawi ya carbides), yomwe imakulitsa kwambiri moyo wa chida chifukwa cha ntchito yake yabwino yosamutsa kutentha.
(3) Kulimbana kwamphamvu kwa zida za PCD nthawi zambiri kumakhala 0.1 mpaka 0.3, yotsika kwambiri kuposa ya carbides, yomwe imatha kuchepetsa mphamvu yodula ndikukulitsa moyo wa zida.
(4) Zida za PCD zili ndi coefficient yaying'ono yakukulitsa matenthedwe, mapindikidwe ang'onoang'ono amafuta, kulondola kwaukadaulo wapamwamba komanso mawonekedwe apamwamba a workpiece.
(5) Pamwamba pa zida zodulira za PCD zimakhala ndi mgwirizano wochepa ndi zinthu zopanda chitsulo komanso zopanda zitsulo, kotero sikophweka kupanga chip buildup.
(6) Zida za PCD zimakhala ndi zotanuka kwambiri modulus ndipo sizimakonda kusweka.Mawonekedwe osawoneka bwino a m'mphepete mwake amatha kukhala ochepa kwambiri, omwe amatha kukhala akuthwa kwa nthawi yayitali.
Kutengera zabwino zomwe tafotokozazi, zida za PCD zimatha kukonza zida za aluminiyamu pa liwiro lalikulu kwambiri, ndi moyo wa zida za zikwi zingapo mpaka makumi masauzande a zidutswa.Oyenera makamaka kupanga misa yodula kwambiri komanso yothamanga kwambiri (3C digito, makampani opanga magalimoto, malo opangira ndege), monga kukonza zipolopolo zamakina a digito, ma pistoni agalimoto, mawilo agalimoto, mphete zodzigudubuza, ndi zina zambiri.
Momwe mungasankhire Zida zodulira PCD?
Nthawi zambiri, kukula kwa tinthu ta PCD kumapangitsa kuti chidacho chikhale cholimba.
Nthawi zambiri, tinthu tating'onoting'ono ta PCD timagwiritsidwa ntchito popanga makina olondola kapena opitilira muyeso, pomwe zida za PCD zomata zimagwiritsidwa ntchito popanga movutikira.
Opanga zida nthawi zambiri amalimbikitsa kugwiritsa ntchito ma PCD opangidwa bwino kuti agwiritse ntchito silicon aluminium alloy alloy alloy, komanso kugwiritsa ntchito ma PCD amtundu wa coarse-grained pokonza zida zapamwamba za silicon aluminium alloy, pazifukwa zomwezo.
Ubwino wa pamwamba kukonzedwa ndi PCD zida osati zimadalira tinthu kukula kwa chida, komanso khalidwe la m'mphepete chida, kotero khalidwe la zida PCD ayenera kukhala bwino.
Pali njira ziwiri zogwiritsidwira ntchito m'mphepete mwa zida za PCD, imodzi ndikudula pang'onopang'ono waya.Njirayi ili ndi ndalama zochepa zopangira, koma ubwino wa m'mphepete mwake ndi pafupifupi.Njira ina imatheka kudzera laser processing, amene ali ndi mtengo wokwera pang'ono, koma khalidwe la kudula m'mphepete ndi apamwamba kwambiri (palinso njira yoyamba laser akhakula Machining ndiyeno akupera mwatsatanetsatane Machining, amene ali ndi khalidwe la kudula. m'mphepete).M'pofunikabe kumvetsera kwambiri posankha.
Mwachidule, ndizo zonse.Mfundo zina zachindunji, kuphatikizapo mtengo ndi kudula magawo, ziyeneranso kutchula magawo enieni a mankhwala operekedwa ndi opanga osiyanasiyana.Kuphatikiza apo, kuwonjezera pa kusankha koyenera kwa zida za geometry ndi magawo odulira, kukonza aluminiyamu nthawi zina kumafuna kuti ogulitsa zida azipereka mayankho pamavuto omwe amakumana nawo pakagwiritsidwa ntchito zida.
