Txias Thiab Kub Nias Ntawm Pob Zeb Diamond Segments

Covntuplays lub luag haujlwm tseem ceeb hauv cov cuab yeej txiav thiab yog ib feem tseem ceeb ntawm kev txiav cov hniav. Cov hauv qab no yuav qhia txog nws txoj kev tsim khoom.

Covpob zeb diamond ntumuab faib ua ob txheej txheem: txias nias thiab kubnias.

Thaum cov txheej txheem ib txwm ua rau cov pob zeb diamond ntu nrog grooves ntawm ob sab, nws muab faib ua ob kauj ruam, thawj zaug yog ntu txias nias, thiab tom qab ntawd ntu yog kub nias.

Pob zeb diamond ntuTxias pressing txheej txheem:

Nws yog ncaj qha tsim cov duab uas yuav tsum tau los ntawm lub taub hau cutter ntawm lub txias-nias tuag. Lub tshuab txias txias muaj xws li tsib ntu: sab sauv sab sauv, sab hauv sab hauv qab, lub phaj nruab nrab, phaj pem hauv ntej kawg, thiab phaj nram qab kawg. Kev npaj ntawm qhov chaw yog siv los ua lub taub hau cutter. Rau qhov yuav tsum tau muaj kab noj hniav, kho lub periphery ntawm lub txias-pressed pwm kom cov kab noj hniav yuav tsis deform tom qab raug pressurized, thiab ces ntxiv cov hmoov uas yuav tsum tau nyob rau hauv lub kab noj hniav thiab thauj mus rau hauv lub Upper indenter.

Pressurize, nres lub pressurization thaum cov hmoov hloov los ntawm loosening mus rau cov khoom zoo ntawm lub siab xav cutter lub taub hau zoo, cais cov kho cov cuab yeej nyob ib ncig ntawm lub txias pressing pwm, thiab cais lub txias pressing pwm, tshem tawm lub cutter hau ib tug los ntawm ib tug, thiab npaj. cov riam tsis tu ncua manually. taub hau, npaj siv.

Pob zeb diamond ntu kub nias txheej txheem:

Ntawd yog, ntu txias-nias yog muab tso rau ntawm cov pwm kub nias, thiab cov pwm kub nias muaj tsib ntu: sab sauv sab sauv, sab hauv sab hauv qab, nruab nrab phaj, phaj kawg, thiab sab phaj. Cov khoom tau npaj ua ntu zus los ua cov kab noj hniav, Muab cov txheej txheem txias txias rau hauv cov kab noj hniav, kho qhov periphery ntawm cov pwm kub nias, thiab muab tso rau hauv cov khoom siv sintering, kom cov pob zeb diamond seem yog melted nyob rau hauv sov siab. los ua ib qho alloy, thiab thaum kawg tsim, thaum kawg txias thiab decompressed, tshem tawm thiab nruj ntaus ntawv, tshem tawm cov ntu.

Nyob rau hauv cov txheej txheem ntau lawm ntawm ntu, kev xaiv ntawm lub taub hau cutter carcass khoom thiab cov txheej txheem kub nias yog qhov tseem ceeb tshaj qhov txuas. Co-based thiab bronze-based alloys tau xaiv dav raws li cov khoom siv carcass, tab sis lawv tsis tuaj yeem ua tiav raws li cov nqi tsim khoom thiab kev ua haujlwm. Ib tug zoo heev clone. Fe-Ni-Cu-W alloy yog npaj ua cov khoom ntawm lub taub hau cutter carcass los ntawm kab rov tav tsom. Tom qab kev sim thiab daim ntawv thov, qhov zoo tshaj plaws clone ntawm cov nqi tsim khoom thiab kev ua haujlwm tau txais.

Cov txheej txheem ntau lawm ntawm pob zeb diamond ntu tuaj yeem piav qhia raws li cov txheej txheem sintering ntawm cov hmoov hlau nyob rau hauv ib qho kev siab, uas yog cov txheej txheem hmoov metallurgy: uniformly tov hlau hmoov yog rhuab ntawm qhov kub (800-1000 degree) thiab ib tug tej yam siab ( 180-250Kgf/cm2)), los ntawm ntau lub cev thiab tshuaj impregnation, xws li dispersion, fusion welding, compounding, thiab recrystallization ntawm hmoov hais, tsim ib lub cev sintered nrog ib tug tej yam zoo thiab txhua yam khoom, uas yog , ib ntu.
