Chiyambi cha zida za mpeni wa Carbide!
Zida za mpeni wa Carbide
Zida za mpeni wa Carbide, makamaka Zida za mpeni wa Carbide zomwe zimayikidwa mu index, ndizo zinthu zomwe zimagwiritsidwa ntchito kwambiri mu zida zomangira za CNC. Kuyambira m'ma 1980, mitundu yosiyanasiyana ya Zida za mpeni wa Carbide zolimba komanso zoyikidwa mu index zakhala zikufalikira m'magawo osiyanasiyana a zida zodulira. Zida za mpeni wa Carbide zomwe zimayikidwa mu index zakhala zikusintha kuchokera ku zida zosavuta zosinthira ndi zodulira nkhope kupita ku zida zosiyanasiyana zolondola, zovuta, komanso zopangira.
A. Mitundu ya Zida za Mpeni wa Carbide
Kugawa ndi Main Chemical Composition
Zida za mpeni wa Carbide zitha kugawidwa m'magulu awiri: carbides zochokera ku tungsten carbide ndi titanium carbonitride (TiC(N)).
Ma carbide okhala ndi tungsten carbidekuphatikizapo:
● YG (tungsten-cobalt): Kulimba kwambiri koma kulimba kochepa.
● YT (tungsten-cobalt-titanium): Kulimba bwino komanso kulimba.
● YW (yokhala ndi ma carbide osowa): Makhalidwe abwino okhala ndi zowonjezera monga TaC kapena NbC.
Zigawo zazikulu zikuphatikizapo tungsten carbide (WC), titanium carbide (TiC), tantalum carbide (TaC), ndi niobium carbide (NbC), ndipo cobalt (Co) ndiye chomangira chachitsulo chodziwika bwino.
Ma carbide okhala ndi titanium carbonitride amagwiritsa ntchito TiC ngati gawo lalikulu, nthawi zambiri limodzi ndi ma carbide ena kapena ma nitride, ndi Mo kapena Ni ngati zomangira.
Gulu la ISO
Bungwe la International Organisation for Standardization (ISO) limagawa magawo atatu a carbides:
● Gulu la K (K10–K40): Lofanana ndi YG (WC-Co), la chitsulo chosungunuka ndi zitsulo zopanda chitsulo.
● Gulu la P (P01–P50): Lofanana ndi YT (WC-TiC-Co), la chitsulo.
● Kalasi ya M (M10–M40): Yofanana ndi YW (WC-TiC-TaC(NbC)-Co), yogwiritsidwa ntchito m'njira zosiyanasiyana.
Magiredi amawerengedwa kuyambira 01 mpaka 50, kusonyeza kusiyana kuyambira kuuma kwambiri mpaka kulimba kwambiri.
B. Makhalidwe Abwino a Zida za Mpeni wa Carbide
● Kulimba Kwambiri
Zipangizo za mpeni wa Carbide zimapangidwa ndi ufa pogwiritsa ntchito zitsulo zochokera ku ma carbide olimba kwambiri, ma carbide osungunuka kwambiri (gawo lolimba) ndi zomangira zitsulo (gawo lomangirira). Kulimba kwawo kumayambira pa 89–93 HRA, kokwera kwambiri kuposa chitsulo chothamanga kwambiri (HSS). Pa 540°C, kulimba kumakhalabe pa 82–87 HRA, kofanana ndi HSS kutentha kwa chipinda (83–86 HRA). Kulimba kumasiyana malinga ndi mtundu wa carbide, kuchuluka, kukula kwa tirigu, ndi kuchuluka kwa zomangira, nthawi zambiri kumachepa pamene kuchuluka kwa zomangira kukuwonjezeka. Pa kuchuluka komweko kwa zomangira, ma alloy a YT ndi olimba kuposa ma alloy a YG, ndipo ma alloy okhala ndi TaC(NbC) ali ndi kulimba kwakukulu kwa kutentha.
●Mphamvu Yosinthasintha ndi Kulimba
Mphamvu yopindika ya ma carbide wamba imayambira pa 900–1500 MPa. Kuchuluka kwa ma binder kumawonjezera mphamvu yopindika. Pa kuchuluka komweko kwa ma binder, ma alloy a YG (WC-Co) ndi amphamvu kuposa ma alloy a YT (WC-TiC-Co), ndipo mphamvu imachepa pamene kuchuluka kwa TiC kukuwonjezeka. Ma carbide ndi ofooka, ndipo kulimba kwa kukhudza kutentha kwa chipinda ndi 1/30 mpaka 1/8 yokha kuposa ya HSS.
C. Kugwiritsa Ntchito Zida za Mpeni wa Common Carbide
●Ma Carbide a YG Class
Ma alloy a YG amagwiritsidwa ntchito kwambiri popanga chitsulo chopangidwa ndi chitsulo, zitsulo zopanda chitsulo, ndi zinthu zopanda chitsulo. Ma alloy a YG okhala ndi tinthu tating'onoting'ono (monga YG3X, YG6X) ali ndi kuuma kwambiri komanso kukana kuwonongeka kuposa ma alloy apakatikati okhala ndi cobalt yofanana, yoyenera kupanga chitsulo chopangidwa ndi ...
●Ma Carbide a YT Class
Ma alloy a YT ali ndi kuuma kwambiri, kukana kutentha bwino, komanso kuuma kutentha kwambiri komanso mphamvu yokakamiza kuposa ma alloy a YG, omwe ali ndi kukana kwabwino kwa okosijeni. Ndi abwino kwambiri pakugwiritsa ntchito kutentha kwambiri komanso kukana kuvala ndipo ndi oyenera kugwiritsa ntchito zipangizo zapulasitiki monga chitsulo koma osati titaniyamu kapena ma alloy a silicon-aluminium. Ma grade apamwamba a TiC ndi omwe amakondedwa kuti azitha kukana kutentha kwambiri komanso kukana kuvala.
● Ma Carbide a YW Class
Ma aloyi a YW amaphatikiza mawonekedwe a ma aloyi a YG ndi YT, zomwe zimapangitsa kuti ntchito yawo ikhale yabwino kwambiri. Ndi oyenera kugwiritsa ntchito chitsulo chopangira zinthu, chitsulo chopangidwa ndi chitsulo, ndi zitsulo zopanda chitsulo. Ndi kuchuluka kwa cobalt, ma aloyi a YW amakhala ndi mphamvu zambiri, zomwe zimapangitsa kuti akhale abwino kwambiri popangira zinthu zovuta komanso kudula zinthu zovuta kugwiritsa ntchito.
