Ibyiciro kandiStudy onIbikoresho byo gutema Carbide

Igice cya mbere

Igikoresho nigikoresho cyingirakamaro mugukata gutunganya, cyaba igikoresho gisanzwe cyimashini, cyangwa igikoresho cyimashini igenzura imibare (NC), ikigo cyimashini (MC) hamwe na sisitemu yo gukora byoroshye (FMC), igomba kwishingikiriza kubikoresho kugirango irangize gukata inzira. Iterambere ryibikoresho rifite ingaruka zitaziguye mu kuzamura umusaruro no gutunganya ubuziranenge. Ibikoresho, imiterere na geometrie nibintu bitatu bigena imikorere yo gukata igikoresho, aho imikorere yibikoresho igira uruhare runini.

Nkigice cyingenzi cyibikoresho, carbide ya sima ifite uruhare rudasubirwaho mugutunganya kijyambere. Carbide ya sima ni ubukana bwinshi, karbide yicyuma (WC, TiC, nibindi) ya micron itondekanya ifu yubunini, igacumura hamwe na Co, Mo, Ni nibindi bicuruzwa byifu ya metallurgie, muribwo karbide yubushyuhe bwo hejuru burenze hejuru -ibyuma byihuta, ubushyuhe bwo kwemererwa gukata bugera kuri 800 ~ 1000 ℃, ubukonje busanzwe bwa HRC89 ~ 93, 760 ℃ ubukana bwa HRC77 ~ 85, guca umuvuduko kugera kuri 100 ~ 300m / min, birenze kure ibyuma byihuta, ubuzima ni inshuro nyinshi kugeza kuri mirongo inshuro nyinshi ibyuma byihuta, ariko imbaraga nubukomezi ni 1/30 ~ 1/8 cyibyuma byihuta, ubushobozi buke bwo kwihanganira ihungabana n'ingaruka. Noneho ibaye kimwe mubikoresho byingenzi byingenzi.

Umuryango mpuzamahanga ushinzwe ubuziranenge (ISO) ugabanya karbide yo gukata ibikoresho mu byiciro bitandatu:

1. Andika P.

Igizwe na WC, Co na 5% ~ 30% TiC, izwi kandi nka tungsten titanium cobalt carbide, icyiciro YT5, YT14, YT15, YT30, muri byo ibirimo TiC ni 5%, 14%, 15%, 30%, bihuye Ibirimo Co ni 10%, 8%, 6%, 4%, ubukana HRA91.5 ~ 92.5. Tyunamye imbaraga ni 900 ~ 1400MPa. Ibirimo bya TiC byariyongereye, Ibirimo Co byagabanutse, ubukana no kwambara biriyongera, ariko ingaruka zikomeye zaragabanutse cyane. Ubu bwoko bwa alloy bufite ubukana bwinshi kandi bwambara, kwihanganira neza no gukwirakwiza no kurwanya okiside. Ariko imbaraga zunama, gusya imikorere hamwe nubushyuhe bwumuriro bigabanuka, ubushyuhe buke bwubushyuhe, ubukana ni bubi. Birakwiriye kwihuta gukata ibikoresho byuma. Iyo hejuru ya Co ibirimo ibinyobwa, niko imbaraga zunama ningaruka zikomeye, bikwiranye no gukomera. Ibirimo Co biragabanuka, ubukana, kwambara no kurwanya ubushyuhe biriyongera, kandi birakwiriye kurangiza. Ubusabane hagati ya Ti element muri alloy na Ti element muriakaziBizabyara ibikoresho bikomeye bifatika, bizamura imyambarire mugihe cyo kugabanya ubushyuhe bwinshi hamwe nimpamvu nini yo guterana amagambo, kandi ntibikwiye gutunganywa ibyuma bitagira umwanda na titanium.

2. Andika K.

Igizwe na WC na Co, izwi kandi nka tungsten cobalt tungsten karbide, ikunze gukoreshwa mu byiciro YG6, YG8, YG3X, YG6X, irimo Co ya 6%, 8%, 3%, 6%. Gukomera HRA89 ~ 91.5, imbaraga zo kugonda 1100 ~ 1500GPa. Imiterere igabanijwemo ingano nini, ingano yo hagati ningano nziza. Mubisanzwe (nka YG6, YG8) kumiterere yintete ziciriritse, karbide nziza yintete (nka YG3X, YG6X) irimo Co ingana na Co kurenza ubukana bwimbuto ziciriritse,yayokwambara birwanya hejuru gato, imbaraga zunama nagukomeranimunsi gato. Ubu bwoko bwa alloy gukomera, gusya, ubushyuhe bwumuriro nibyiza, bikwiranye no gutunganya ibikoresho byoroshye.

3. Andika M.

Hashingiwe kuri WC, TiC na Co, TaC (cyangwa NbC) yongewemo mubigize, wongeyeho TaC (NbC) muri YT birashobora kunoza imbaraga zunama, imbaraga zumunaniro, ubukana bwingaruka, ubukonje bukabije, imbaraga hamwe no kurwanya okiside, kwambara kurwanywa n'ibindi. Bikunze gukoreshwa amanota YW1 na YW2. Irashobora gukoreshwa mugutunganya ibyuma, ibyuma bidafite fer nicyuma, ariko kandi birashobora gutunganya ubushyuhe bwo hejuru cyane, ibyuma bitagira umwanda nibindi bigoye-to-ibikoresho.

4. Andika H.

Ahanini ikoreshwa mugukata ibikoresho bikomeye, nkibyuma bikomeye, ibyuma bikonje bikonje nibindi. Cubic boron nitride PCBN iri kurutonde rwa H.

5.Andika S.

Ikoreshwa mugukata ibikoresho birwanya ubushyuhe,super-alloys, n'ibindi.

6.Andika H.

Ikoreshwa mugukata ibyuma bidafite ferrous. Polycrystalline diamant PCD ishyirwa mubyiciro N.

Muri iyi ngingo, navuze ubwoko butandatu bwa karbide ya sima mugushira mubikorwa ibikoresho byo gutema, igice gikurikira, hazaba hari ubwoko bushya bwa karbide ya sima kugirango dusoze, nyamuneka don’ntiwibagirwe kugenzura igice gikurikira niba ubishaka.

ZZBETTER itanga ibicuruzwa bya TC / WC bifite uburambe bwimyaka irenga 10, twandikire niba hari icyo usabwa kubyerekeye ibikoresho bya karubide ya tungsten cyangwa ibicuruzwa bigoye. Tegereza iperereza ryawe, rwose turi abizerwa.
