Menene halayen kayan aikin yankan carbide?
Kayan aikin Carbide, musamman kayan aikin carbide masu ƙididdigewa, sune manyan samfuran kayan aikin injin CNC. Tun daga shekarun 1980, nau'ikan kayan aikin carbide masu ƙarfi da ƙididdiga, ko abubuwan da ake sakawa, sun faɗaɗa zuwa filin sarrafawa daban-daban. Kayan aiki, yi amfani da kayan aikin carbide mai ƙididdigewa don faɗaɗa daga kayan aiki masu sauƙi da masu yankan fuska zuwa daidaici, hadaddun, da ƙirƙirar kayan aikin. Don haka, menene halayen kayan aikin carbide?
1. Maɗaukakiyar ƙarfi: Kayan aikin yankan siminti na siminti ana yin su ne da carbide tare da tauri mai ƙarfi da wurin narkewa (wanda ake kira wuya lokaci) da ɗaure ƙarfe (wanda ake kira bonding phase) ta hanyar hanyar ƙarfe na foda, kuma taurinsa shine 89 ~ 93HRA, Yafi girma fiye da na na karfe mai sauri, a 5400C, taurin har yanzu yana iya kaiwa 82-87HRA, wanda yayi daidai da na ƙarfe mai sauri a cikin zafin jiki (83-86HRA). Tauri na siminti carbide ya bambanta da yanayi, yawa, girman hatsi da abun ciki na lokacin daurin ƙarfe, kuma gabaɗaya yana raguwa tare da haɓaka abubuwan haɗin ƙarfe na ƙarfe. Tare da irin wannan abun ciki na mannewa, taurin alloy na YT ya fi na YG alloy girma, yayin da gami da ke ƙunshe da TaC (NbC) yana da taurin mafi girma a yanayin zafi.
2. Lankwasawa ƙarfi da taurin: The lankwasawa ƙarfi na talakawa cimined carbide ne a cikin kewayon 900-1500MPa. Mafi girman abun ciki na lokacin daurin karfe, mafi girman ƙarfin lanƙwasawa. Lokacin da abun ciki mai ɗaure iri ɗaya ne, YG(WC-Co). Ƙarfin ƙyalli ya fi na YT (WC-Tic-Co) gami da ƙarfi, kuma ƙarfin yana raguwa tare da haɓakar abun ciki na TiC. Carbide da aka yi da siminti abu ne mai karye, kuma tasirin sa a zafin jiki shine kawai 1/30 zuwa 1/8 na HSS.
3. Kyakkyawan juriya. Gudun yankan kayan aikin carbide da aka yi da siminti shine sau 4 ~ 7 fiye da na ƙarfe mai sauri, kuma rayuwar kayan aiki shine sau 5 ~ 80 mafi girma. Don kera gyare-gyare da kayan aikin aunawa, rayuwar sabis ɗin shine sau 20 zuwa 150 fiye da na kayan aikin gami da ƙarfe. Yana iya yanke kayan wuya na kusan 50HRC.
Yin amfani da kayan aikin carbide: ana amfani da kayan aikin carbide gabaɗaya a cikin cibiyoyin injin CNC, injin zanen CNC. Hakanan za'a iya shigar da ita akan injin niƙa na yau da kullun don sarrafa wasu ƙayyadaddun ƙayyadaddun kayan aikin zafi marasa rikitarwa.
A halin yanzu, kayan aikin sarrafa kayan haɗin gwiwa, robobi na masana'antu, kayan plexiglass da kayan ƙarfe mara ƙarfe a kasuwa duk kayan aikin carbide ne, waɗanda ke da halayen babban taurin, juriya, ƙarfi mai kyau, juriya mai zafi da juriya na lalata. Hakazalika jerin kyawawan kaddarorin, musamman ma tsayin taurin sa da juriya, ko da ya kasance ba a canzawa a yanayin zafi na 500 ° C, har yanzu yana da babban taurin a 1000 ° C.
Ana amfani da Carbide sosai azaman kayan aiki, kamar kayan aikin juyawa, masu yankan niƙa, injina, ƙwanƙwasa, kayan aikin ban gajiya, da sauransu, don yankan simintin ƙarfe, ƙarfe mara ƙarfe, robobi, filayen sinadarai, graphite, gilashi, dutse, da sauransu. Na yau da kullun. Hakanan za'a iya amfani da karfe don yanke karfe mai jure zafi, bakin karfe, babban karfen manganese, karfen kayan aiki da sauran kayan injin da ke da wahala.
