Kodi zida zodulira carbide ndi ziti?
Zida za Carbide, makamaka indexable carbide tools, ndi zinthu zotsogola kwambiri pa CNC Machining zida. Kuyambira m'ma 1980, zida zosiyanasiyana zolimba ndi zolozera za carbide, kapena zoyikapo, zakula kumadera osiyanasiyana opangira. Zida, gwiritsani ntchito zida zodziwika bwino za carbide kuti muwonjezeke kuchokera ku zida zosavuta komanso zodulira mphero mpaka zida zolondola, zovuta komanso zopangira. Ndiye, zida za carbide ndi ziti?
1. Kulimba kwambiri: Zida zodulira simenti za carbide zimapangidwa ndi carbide yolimba kwambiri komanso yosungunuka (yotchedwa hard phase) ndi metal binder (yotchedwa bonding phase) ndi njira ya powder metallurgy, ndipo kulimba kwake ndi 89~93HRA, yokwera kwambiri kuposa ya zitsulo zothamanga kwambiri, pa 5400C, kuuma kungathebe kufika ku 82-87HRA, komwe kuli kofanana ndi chitsulo chothamanga kwambiri kutentha kutentha (83-86HRA). Kuuma kwa simenti ya carbide kumasiyanasiyana malinga ndi chikhalidwe, kuchuluka kwake, kukula kwambewu ndi zomwe zili mugawo lomangira zitsulo, ndipo nthawi zambiri zimachepa ndi kuchuluka kwa gawo lomanga zitsulo. Ndi gawo lomatira lomwelo, kuuma kwa aloyi ya YT ndikwapamwamba kuposa aloyi ya YG, pomwe alloy yomwe ili ndi TaC (NbC) imakhala ndi kuuma kwakukulu pakutentha kwambiri.
2. Mphamvu yopindika ndi kulimba: Mphamvu yopindika ya carbide wamba ya simenti ili mumitundu ya 900-1500MPa. Pamwamba zomwe zili mu gawo lomanga zitsulo, mphamvu yopindika imakwera. Pamene zomangira zili zofanana, YG(WC-Co). Mphamvu ya alloy ndi yapamwamba kuposa ya YT (WC-Tic-Co) alloy, ndipo mphamvu imachepa ndi kuwonjezeka kwa TiC. Cemented carbide ndi chinthu chophwanyika, ndipo kulimba kwake kutentha ndi 1/30 mpaka 1/8 ya HSS.
3. Good kuvala kukana. Liwiro lodula la zida za carbide zokhala ndi simenti ndi nthawi 4 ~ 7 kuposa chitsulo chothamanga kwambiri, ndipo moyo wa chida ndi 5 ~ 80 nthawi zambiri. Popanga nkhungu ndi zida zoyezera, moyo wautumiki ndi nthawi 20 mpaka 150 kuposa chitsulo cha alloy tool. Itha kudula zida zolimba pafupifupi 50HRC.
Kugwiritsa ntchito zida za carbide: zida za carbide zimagwiritsidwa ntchito m'malo opangira makina a CNC, makina ojambula a CNC. Itha kukhazikitsidwanso pamakina wamba amphero kuti azitha kukonza zida zolimba, zosavuta zothira kutentha.
Pakali pano, zida processing zipangizo gulu, mapulasitiki mafakitale, zipangizo plexiglass ndi zinthu sanali achitsulo zitsulo pa msika zida zonse carbide, amene makhalidwe a kuuma mkulu, kuvala kukana, kulimba bwino, kukana kutentha ndi kukana dzimbiri. Komanso mndandanda wazinthu zabwino kwambiri, makamaka kuuma kwake kwakukulu ndi kukana kuvala, ngakhale zitakhalabe zosasinthika pa kutentha kwa 500 ° C, zimakhalabe zolimba kwambiri pa 1000 ° C.
Carbide imagwiritsidwa ntchito kwambiri ngati zida, monga zida zotembenuza, zodulira mphero, zopulala, zobowolera, zida zoboola, ndi zina zotero, podula chitsulo, zitsulo zopanda chitsulo, mapulasitiki, ulusi wamankhwala, graphite, galasi, miyala, ndi zina zotero. Wamba. Chitsulo chimatha kugwiritsidwanso ntchito kudula zitsulo zosagwira kutentha, zitsulo zosapanga dzimbiri, chitsulo chokwera cha manganese, chitsulo chachitsulo ndi zinthu zina zovuta kupanga makina.
