Carbide ndi chitsulo cholimba kwambiri, chachiwiri kwa diamondi mu kuuma komanso cholimba kwambiri kuposa chitsulo ndi chitsulo chosapanga dzimbiri.Pa nthawi imodzimodziyo, kulemera kwake kumafanana ndi golidi ndipo kulemera kwake kuwirikiza kawiri kuposa chitsulo.Kuonjezera apo, imakhala ndi mphamvu zabwino kwambiri komanso kusungunuka, imatha kusunga kuuma pa kutentha kwakukulu, ndipo sikophweka kuvala.Chifukwa chake, zida za carbide zimagwiritsidwa ntchito nthawi zambiri m'minda yopanga mafakitale monga zida zopangira zitsulo ndi nkhungu.

Gawo 1: Kodi zinthu za carbide ndi chiyani?
Carbide ya simenti imapangidwa ndi tungsten carbide ndi cobalt.Tungsten carbide ndi chinthu chokhala ndi malo osungunuka kwambiri.Iyenera kuphwanyidwa kukhala ufa ndiyeno kupangidwa ndi kuyaka kwapamwamba ndi kulimba, ndipo cobalt imawonjezeredwa ngati chinthu chomangira.Tungsten imachokera makamaka ku China, Russia ndi South Korea, pamene cobalt imachokera ku Finland, Canada, Australia ndi Congo.Chifukwa chake, kupanga ma aloyi olimba kwambiri kumafuna mgwirizano wapadziko lonse lapansi kuti mugwiritse ntchito zinthu zodabwitsazi kuzinthu zosiyanasiyana zosiyanasiyana. titaniyamu-cobalt (niobium).Zomwe zimagwiritsidwa ntchito kwambiri popanga ndi tungsten-cobalt ndi tungsten-titanium-cobalt simenti carbide.
Kuti apange aloyi yolimba kwambiri, ndikofunikira kugaya tungsten carbide ndi cobalt kukhala ufa wosalala, ndikuwotcha ndi kulimba pa kutentha kwakukulu (1300 ° C mpaka 1500 ° C) kuti zikhazikike.Cobalt amawonjezedwa ngati cholumikizira kuti tinthu tating'onoting'ono ta carbide tigwirizane.Chotsatira chake ndi chitsulo cholimba kwambiri chokhala ndi malo osungunuka a 2900 ° C, zomwe zimapangitsa kuti zisawonongeke ndi kutentha kwambiri komanso zoyenera kuti zikhale zotentha kwambiri.
Gawo 2: Kodi kugwiritsa ntchito carbide ndi chiyani?
Carbide ya simenti ili ndi ntchito zambiri.M'munda wa mafakitale kupanga, chimagwiritsidwa ntchito popanga zida kudula kwa processing zitsulo monga CNC pobowola zida, CNC mphero makina, ndi CNC lathes.Kuonjezera apo, angagwiritsidwe ntchito popanga nkhungu za zitini za aluminiyamu monga khofi yam'chitini ndi zakumwa, zojambulajambula za ufa zamagulu a injini zamagalimoto (zigawo za sintered), ndi nkhungu zamagetsi zamagetsi monga mafoni a m'manja.
Pankhani ya kupanga ndi kukonza, kufunikira kwa alloy wapamwamba kwambiri kumawonekera.Chifukwa cha kuuma kwake kwakukulu ndi mphamvu zake, ma alloys apamwamba kwambiri amagwiritsidwa ntchito kwambiri pazida zamakina monga zida zodulira zitsulo, zida zobowola, makina opangira mphero ndi lathes.Komanso, angagwiritsidwe ntchito kupanga zitsulo zotayidwa akhoza zisamere pachakudya zamzitini khofi ndi zakumwa, zisamere ufa akamaumba kwa mbali injini magalimoto (sintered mbali), ndi zisamere pachakudya zigawo zikuluzikulu zamagetsi monga mafoni a m'manja, etc.
Komabe, ma alloys apamwamba kwambiri samangogwira ntchito yokonza zitsulo ndi kupanga.Itha kugwiritsidwanso ntchito pophwanya miyala yolimba, monga kupanga ngalande za zishango, kudula misewu ya phula ndi minda ina.Kuphatikiza apo, chifukwa cha mawonekedwe ake abwino kwambiri, ma aloyi apamwamba kwambiri amathanso kugwiritsidwa ntchito m'magawo ena a CNC Machining.Mwachitsanzo, zida zopangira opaleshoni zomwe zimagwiritsidwa ntchito m'chipatala, zipolopolo ndi zida zankhondo m'gulu lankhondo, zida za injini ndi masamba opangira ma turbine a ndege m'munda wazamlengalenga, ndi zina zambiri.
Kuphatikiza pakugwiritsa ntchito m'makampani, ma alloys apamwamba kwambiri amathandizanso pantchito yofufuza zasayansi.Mwachitsanzo, angagwiritsidwe ntchito kupanga diffraction ndodo mu X-ray ndi kafukufuku kuwala, ndi monga chothandizira pa kafukufuku wa zochita za mankhwala.
Gawo Lachitatu: Kodi vuto la carbide part Machining ndi chiyani?
Kukonzekera kwa simenti ya carbide sikophweka ndipo pali zovuta zambiri.Choyamba, chifukwa cha kuuma kwake kwakukulu ndi brittleness, njira zachikhalidwe zogwirira ntchito nthawi zambiri zimakhala zovuta kukwaniritsa zofunikira ndipo zimatha kubweretsa zolakwika monga ming'alu ndi kupunduka kwa mankhwala.Kachiwiri, carbide yopangidwa ndi simenti imagwiritsidwa ntchito m'minda yapamwamba, kotero kuti zofunikira pakuwongolera makina ndizokwera kwambiri.Pakukonza, zinthu zambiri ziyenera kuganiziridwa, monga zida zodulira, zosintha, magawo azinthu, ndi zina zambiri, kuti zitsimikizire kulondola kwazinthu.Pomaliza, zofunikira zamtundu wa carbide zokhala ndi simenti ndizokwera kwambiri.Chifukwa cha brittleness yake yaikulu, pamwamba pake imawonongeka mosavuta, kotero njira zapadera zogwirira ntchito ndi zipangizo (monga ultra-precision grinders, electrolytic polishers, etc.) ziyenera kugwiritsidwa ntchito kuti zitsimikizidwe kuti zili bwino.
Mwachidule, carbide ya simenti imagwiritsidwa ntchito kwambiri mu makina a CNC, ikugwira ntchito yofunika kwambiri popititsa patsogolo kupanga bwino komanso khalidwe lazogulitsa mu makina, zamagetsi, mankhwala, zakuthambo ndi mafakitale ena.GPM ili ndi zipangizo zamakono zopangira zinthu komanso zamakono zomwe zimatha kukonza mbali za supercarbide bwino komanso molondola. .Dongosolo lokhazikika loyang'anira khalidwe panthawi yokonza limatsimikizira kuti gawo lililonse limakwaniritsa zofunikira za makasitomala ndi miyezo.
