Ni ibihe bintu biranga ibikoresho byo guca karbide?
Ibikoresho bya Carbide, cyane cyane ibikoresho byerekana karbide, nibicuruzwa byambere mubikoresho byo gutunganya CNC. Kuva mu myaka ya za 1980, ibikoresho bitandukanye bya karbide bikomeye, cyangwa byinjizwamo, byagutse mubikorwa bitandukanye byo gutunganya. Ibikoresho, koresha ibikoresho bya karbide byerekana kwaguka kuva mubikoresho byoroshye no gukata ibyuma byo gusya kugeza kubikoresho byuzuye, bigoye, kandi bikora ibikoresho. None, ni ibihe bintu biranga ibikoresho bya karbide?
1. Ubukomere bukabije: Ibikoresho byo gutema karbide ya sima bikozwe muri karbide ifite ubukana bwinshi hamwe no gushonga (bita icyiciro gikomeye) hamwe nicyuma gihuza ibyuma (bita fonction bond) hakoreshejwe uburyo bwa powder metallurgie, kandi ubukana bwayo ni 89 ~ 93HRA, hejuru cyane kurenza iyo ibyuma byihuta cyane, kuri 5400C, ubukana burashobora kugera kuri 82-87HRA, ni kimwe nicyuma cyihuta cyane mubushyuhe bwicyumba (83-86HRA). Ubukomezi bwa karbide ya sima buratandukanye na kamere, ubwinshi, ingano yintete nibiri murwego rwo guhuza ibyuma, kandi muri rusange bigabanuka hamwe no kwiyongera kwicyuma gihuza ibice. Hamwe nibice bimwe bifata ibyiciro, ubukana bwa YT alloy burenze ubwa YG alloy, mugihe amavuta arimo TaC (NbC) afite ubukana bwinshi mubushyuhe bwinshi.
2. Kunama imbaraga no gukomera: Imbaraga zunama za karbide isanzwe ya sima iri murwego rwa 900-1500MPa. Iyo hejuru yibiri mubyuma bihuza icyiciro, niko imbaraga zunama. Iyo ibirimo binder ari bimwe, YG (WC-Co). Imbaraga zivanze zirenze iziri YT (WC-Tic-Co), kandi imbaraga ziragabanuka hamwe no kwiyongera kwa TiC. Carbide ya sima ni ibintu byoroshye, kandi ingaruka zabyo mubushyuhe bwicyumba ni 1/30 kugeza 1/8 cya HSS.
3. Kurwanya kwambara neza. Umuvuduko wo kugabanya ibikoresho bya sima ya sima ikubye inshuro 4 ~ 7 kurenza icyuma cyihuta, kandi ubuzima bwibikoresho burenze inshuro 5 ~ 80. Kubikorwa byo kubumba no gupima ibikoresho, ubuzima bwa serivisi bureshya inshuro 20 kugeza kuri 150 kurenza ubw'ibikoresho byifashishwa. Irashobora guca ibikoresho bikomeye bya 50HRC.
Gukoresha ibikoresho bya karbide: ibikoresho bya karbide mubisanzwe bikoreshwa mubigo bitunganya CNC, imashini zishushanya CNC. Irashobora kandi gushirwa kumashini isanzwe yo gusya kugirango itunganyirize ibikoresho bimwe bigoye, bitoroshye.
Kugeza ubu, ibikoresho byo gutunganya ibikoresho byinshi, plastiki yinganda, ibikoresho bya plexiglass nibikoresho byuma bidafite ferrous kumasoko nibikoresho byose bya karbide, bifite ibimenyetso biranga ubukana bwinshi, kwambara nabi, gukomera kwinshi, kurwanya ubushyuhe no kurwanya ruswa. Kimwe nuruhererekane rwibintu byiza cyane, cyane cyane ubukana bwarwo no kwihanganira kwambara, kabone niyo byakomeza kuba bidahindutse ku bushyuhe bwa 500 ° C, buracyafite ubukana bwinshi kuri 1000 ° C.
Carbide ikoreshwa cyane nkibikoresho byibikoresho, nkibikoresho byo guhindura, gukata urusyo, abapanga, imyitozo, ibikoresho birambirana, nibindi, mugukata ibyuma, ibyuma bidafite fer, plastike, fibre chimique, grafite, ikirahure, amabuye, nibindi bisanzwe. ibyuma birashobora kandi gukoreshwa mugukata ibyuma birwanya ubushyuhe, ibyuma bidafite ingese, ibyuma bya manganese ndende, ibyuma byibikoresho nibindi bikoresho bigoye kumashini.
