Nrog rau txoj kev loj hlob sai ntawm kev lag luam steel, txhawm rau txhim kho qhov tso zis ntawm cov hlau, txhim kho kev siv tus nqi thiab kev ua haujlwm ntawm cov dov zeb, thiab txo cov naj npawb ntawm kev kaw ntawm lub tshuab.dov zeb, carbidemmobroll uasand yob rings tau tshwm sim raws li lub sij hawm xav tau, thiab yog dav siv nyob rau hauv high-speed hlau qws dov.qhov system.
Thaum ntxov, tib neeg feem ntau siv cov txheej txheem sib tsoo los ua cov cemented carbidezeb yobs, tab sis kev sib tsoo efficiency tsawg dhau, uas cuam tshuam rau kev tsim khoom.Thaum kawg, cov cuab yeej siv uas tuaj yeem hloov pauv hloov kev sib tsoo yog tsim, thiab tig yog siv los hloov cov txheej txheem sib tsoo ntxhib, uas ua rau muaj txiaj ntsig zoo ntawm cov cemented carbide rolls thiab txo cov nqi tsim khoom.
Nyob rau hauv tus txheej txheem ntawm tig cemented carbidezeb yobs, lub hardness ntawm lub cuab yeej nws tus kheej yuav tsum siab tshaj qhov hardness ntawm lub workpiece yuav tsum tau ua.Yog li ntawd, tam sim no cov cuab yeej txiav cov ntaub ntawv rau xa cov cemented carbide rolls feem ntau yog high-hardness, high-heat-resistant non-metallic binders cubic boron nitride thiab pob zeb diamond.tus tswv tsev.
Carbide yob txoj kev ua thiab xaiv cov cai ntawm cov cuab yeej:
1. Saib qhov hardness: Carbide rols wbith hardness tsawg dua HRA90 tuaj yeem xaiv cov khoom siv HLCBN lossis BNK30 cov khoom siv rau kev tig nrog cov nyiaj loj, thiab tig cov carbide yob nrog cov nyiaj loj yuav tsis tawg lossis hlawv cov cuab yeej.Thaum lub hardness ntawm cov cemented carbide yob yog ntau dua HRA90, qhov kev ua ntau yam ntawm cov cuab yeej cubic boron nitride tau dhau lawm.Feem ntau, cov cuab yeej pob zeb diamond ntawm CDW025 cov khoom siv los yog cov pob zeb diamond sib tsoo log yog siv rau kev sib tsoo.Feem ntau, qhov siab dua qhov hardness, cov khoom yuav nkig ntau dua.Thaum cov cemented carbide raug txiav, txiav ntug yuav "slagging lossis chipping", uas yuav ua rau cov khoom tawg.Yog li ntawd, nws yog qhov ceev faj ntau dua los txiav cov khoom siv hardness.Ob leeg ua chamfering ua ntej, los yog siv qhov tseeb ua ntej.Tso nyiaj sib tsoo zoo kom tsis txhob muaj.
2. Saib cov nyiaj pub rau machining thiab kev ua: yog tias cov txheej txheem sab nrauv lossis qhov zawj saum R3 ntawm lub tsheb tau ua tiav, thiab cov nyiaj pub dawb yog loj, feem ntau siv cov khoom siv HLCBN lossis BNK30 cov khoom siv rau kev ua haujlwm ntxhib, thiab tom qab ntawd siv lub log sib tsoo rau sib tsoo (resin bond pob zeb diamond).Sib tsoo log sib tsoo ntawm lub voj voog sab nrauv lossis dav hlau, yob zawj zawj thiab lwm yam sib tsoo feem ntau siv electroplating lossis hlau daim ntawv cog lus pob zeb diamond sib tsoo log);rau me me machining nyiaj pub dawb, yog siv lub log sib tsoo rau kev sib tsoo ncaj qha, lossis siv cov cuab yeej pob zeb diamond rau kev ua haujlwm profile (xws li cov txheej txheem chamfering thiab grooving txheej txheem, koj tuaj yeem xaiv cov cuab yeej pob zeb diamond customized);Feem ntau hais lus, txiav es tsis txhob sib tsoo tuaj yeem txhim kho kev ua tau zoo, thiab txoj kev txiav ntawm carbide chips yooj yim dua rov qab;vim hais tias kev hloov kho ntawm kev sib tsoo log yuav tsum muaj lub voj voog lossis pwm yog qhov yuav tsum tau ua, tab sis qhov tsis yog tus qauv customization ntawm cov cuab yeej sib sau yog ceev ceev, yog li txoj kev txiav yog qhov tsim nyog rau kev txhim kho lub voj voog ntau lawm.
3. Thaum ribbing lub crescent zawj ntawm yob, CDW025 pob zeb diamond engraving thiab milling cutter (tseem hu ua flying cutter, rotary cutter) yog siv.
4. Cov yob tau muab faib ua cov khoom tshiab thiab kev sib tsoo.Cov txheej txheem saum toj no tsis yog tsuas yog siv rau kev siv thaum cov yob tshiab tau tsim nyob rau hauv cemented carbide yob factories, tab sis kuj tuaj yeem siv rau kev sib tsoo cemented carbide yob hauv steel mills.
Thaum machining cemented carbidezeb yobs, cov cuab yeej yuav passivated.Lub npe hu ua passivation kev kho mob yog los daws qhov tsis xws luag ntawm micro-notch ntawm lub cuab tam ntug tom qab sharpening, txo los yog tshem tawm cov ntug tus nqi, thiab ua kom smoothness thiab smoothness.Lub hom phiaj ruaj khov thiab ruaj khov.Txawm li cas los xij, kev kho mob passivation yuav tsum tsis txhob loj dhau, vim hais tias qhov kev sib cuag ntawm ntug ntawm cov cuab yeej yuav loj dua tom qab passivation, thiab txiav kuj nce ntxiv.
