Ambiri ntchitosimenti carbidesamagawidwa m'magulu atatu malinga ndi kapangidwe kawo ndi machitidwe awo: tungsten-cobalt, tungsten-titanium-cobalt, ndi tungsten-titanium-tantalum (niobium). Zomwe zimagwiritsidwa ntchito kwambiri popanga ndi tungsten-cobalt ndi tungsten-titanium-cobalt simenti carbides.
(1) Tungsten-cobalt simenti carbide
Zigawo zazikuluzikulu ndi tungsten carbide (WC) ndi cobalt. Dzina lachizindikiro limayimiridwa ndi code YG (yolembedwa ndi pinyin yaku China ya "hard" ndi "cobalt"), kutsatiridwa ndi kuchuluka kwa mtengo wa cobalt. Mwachitsanzo, YG6 imayimira tungsten-cobalt cemented carbide yokhala ndi cobalt 6% ndi tungsten carbide 94%.
(2) Tungsten titanium cobalt carbide
Zigawo zazikuluzikulu ndi tungsten carbide (WC), titanium carbide (TiC) ndi cobalt. Dzina lachidziwitso limayimiridwa ndi code YT (chiyambi cha pinyin yaku China ya "hard" ndi "titaniyamu"), kutsatiridwa ndi kuchuluka kwa mtengo wa titanium carbide. Mwachitsanzo, YT15 imayimira tungsten-titanium-cobalt carbide yokhala ndi titanium carbide ya 15%.
(3) Tungsten titaniyamu tantalum (niobium) mtundu simenti carbide
Mtundu uwu wa carbide wopangidwa ndi simenti umatchedwanso general cemented carbide kapena universal cemented carbide. Zigawo zake zazikulu ndi tungsten carbide (WC), titanium carbide (TiC), tantalum carbide (TaC) kapena niobium carbide (NbC) ndi cobalt. Dzina lachizindikiro limayimiridwa ndi khodi YW (yolembedwa ndi pinyin yaku China ya "hard" ndi "wan") yotsatiridwa ndi nambala ya ordinal.
Kugwiritsa ntchito simenti carbide
(1) Zida zothandizira
Carbide ndi ambiri ankagwiritsa ntchito chida zinthu ndipo angagwiritsidwe ntchito potembenuza zida, odula mphero, planers, kubowola bits, etc. Pakati pawo, tungsten-cobalt carbide ndi oyenera yochepa Chip processing wa zitsulo yachitsulo ndi zitsulo sanali achitsulo ndi processing wa zinthu sanali zitsulo, monga chitsulo, kuponyedwa mkuwa, bakelite, etc. tungsten-titaniyamu-cobalt carbide ndi oyenera kwa Chip processing yaitali zitsulo zitsulo monga chitsulo. Chip processing. Pakati pa ma aloyi ofanana, omwe ali ndi cobalt ochulukirapo ndi oyenera kupanga makina ovuta, pomwe omwe alibe cobalt wocheperako ndi oyenera kumaliza. Moyo wokonza wa carbide wamba wazinthu zovuta ku makina monga chitsulo chosapanga dzimbiri ndi wautali kwambiri kuposa wa carbide ina.Carbide tsamba
(2) Zinthu za nkhungu
Carbide imagwiritsidwa ntchito makamaka ngati kujambula kozizira kumafa, kubaya kozizira kumafa, kuzizira kozizira kumafa, pier yozizira imafa ndi ntchito zina zozizira zimafa.
Pansi pa ntchito zosagwirizana ndi kuvala zomwe zimakhudzidwa kapena kukhudzidwa kwamphamvu, kufanana kwasimenti carbide oziziramutu umafa ndikuti carbide yopangidwa ndi simenti imafunika kuti ikhale yolimba kwambiri, kulimba kwa fracture, mphamvu ya kutopa, mphamvu yopindika komanso kukana kuvala bwino. Nthawi zambiri, ma cobalt apakati komanso apamwamba komanso ma aloyi apakati komanso olimba amasankhidwa, monga YG15C.
Nthawi zambiri, ubale pakati pa kukana kuvala ndi kulimba kwa simenti ya carbide ndi wotsutsana: kuwonjezeka kwa kukana kuvala kumabweretsa kuchepa kwa kulimba, ndipo kuwonjezereka kwamphamvu kungayambitse kuchepa kwa kukana kuvala. Chifukwa chake, posankha masukulu ophatikizika, ndikofunikira kukwaniritsa zofunikira zogwiritsira ntchito potengera zinthu zomwe zikugwiritsidwa ntchito komanso momwe amagwirira ntchito.
Ngati giredi yosankhidwayo imakonda kusweka koyambirira komanso kuwonongeka mukamagwiritsa ntchito, muyenera kusankha kalasi yokhala ndi kulimba kwambiri; ngati kalasi yosankhidwa imakonda kuvala koyambirira komanso kuwonongeka mukamagwiritsa ntchito, muyenera kusankha kalasi yokhala ndi kuuma kwakukulu komanso kukana kuvala bwino. . Maphunziro otsatirawa: YG6C, YG8C, YG15C, YG18C, YG20C kuchokera kumanzere kupita kumanja, kuuma kumachepa, kukana kuvala kumachepa, ndipo kulimba kumawonjezeka; komanso mbali inayi.
(3) Zida zoyezera ndi ziwalo zosagwira ntchito
Carbide imagwiritsidwa ntchito popanga zida zoyezera zosavala komanso zida zoyezera, zitsulo zopukutira bwino, mbale zopukusira zopanda pakati ndi ndodo zowongolera, nsonga za lathe ndi zida zina zosamva kuvala.
