Txheej txheem cej luam ntawm Pob Zeb Diamond Tool Formula Design

Cov qauv ntawm cov cuab yeej pob zeb diamond hais txog cov qauv ntawm cov hmoov nias txheej, nrog rau cov mis ntawm cov pob zeb diamond-muaj txheej thiab cov qauv ntawm cov txheej txheem hloov, nrog rau cov concentration, particle loj, qib, thiab lwm yam ntawm pob zeb diamond hais.

1 Lub hauv paus rau kev txiav txim cov qauv

Cov qauv tsim yog raws li ntau yam, feem ntau yog cov ntsiab lus hauv qab no: cov khoom siv ntawm cov khoom ua haujlwm yuav tsum tau ua, cov txheej txheem ua, cov txheej txheem ua tau zoo, cov cuab yeej siv rau kev ua, kev ua tau zoo ntawm cov khoom siv raw, thiab cov txheej txheem tsim khoom. .

​

2 Cov txheej txheem sim ua ntej txiav txim siab cov qauv

Thawj cov qauv ntawm cov qauv tsim los ntawm lub hauv paus tsuas yog kev tsim theoretical xwb. Txawm hais tias nws tuaj yeem ua tau raws lossis ua tau raws li qhov yuav tsum tau ua ntawm txhua yam yuav tsum tau txheeb xyuas los ntawm kev sim ua kom zoo thiab txiav txim siab thaum kawg.

​

Kauj ruam 1: Xaiv cov binder cov khoom xyaw thiab proportions (feem ntau, ob peb proportions yog tsim los rau optimization)

​

Kauj Ruam 2: Txiav txim siab lub zog, hardness thiab lwm yam khoom ntawm cov qauv kev khi, thiab xaiv tus neeg sawv cev khi (ib lossis ob hom) nrog kev ua haujlwm zoo

​

Kauj Ruam 3: Siv tus neeg sawv cev sib tw xaiv los sim-ua cov khoom raws li cov qauv pom thiab txheej txheem txheej txheem.

​

Kauj Ruam 4: Ua ib qho kev sim "txiav" los ntsuas ntau yam khoom ntawm cov khoom los xaiv cov qauv zoo tshaj plaws

3 Pub suav cov mis

Feem ntau, cov khoom siv sintering poob ntawm cov khoom siv pob zeb diamond dav dav yog nce li 5% tom qab xam raws li nws qhov theoretical ntom. Cov mis yog raws li nram no:

​

m=ρ*V

Hauv cov qauv: m--Theoretical pub tus nqi

ρ{0}}Theoretical density of formula

V--Qhov ntim ntawm cov hniav ntawm cov khoom

Lub theoretical ntom ntom ntawm cov mis yog xam los ntawm cov qauv hauv qab no:

ρ{0}}/(g1/ρ1+g2/ρ{4}}...+ gn /ρn)

Hauv cov qauv: g1, g2, ...gn-- feem pua ​​​​ntawm txhua feem hauv cov qauv.

ρ1, ρ2, …ρn-- ceev ntawm cov khoom sib xws.

​

Piv txwv suav: Qhov piv ntawm ib qho qauv (tsis suav nrog pob zeb diamond) yog Fe40%, Sn5%, Ni5%, Cu50%. Muaj pes tsawg grams ntawm cov khoom xav tau rau sintered 40 * 10 * 4 lub taub hau cutter?

​

Kev daws: Cov theoretical ntom ntom ntawm cov qauv yog

​

ρ{0}}/(40/7.8+5/7.3+5/8.9+50/8.9){10}}.34g/cm3

Qhov ntim ntawm lub taub hau cutter yog: V =40*10*4/1000=1.6 cm3

Theoretical pub noj: m=ρ*V=8.34*1.6=13.3g

Kev pub mis tiag tiag: mactual=13.3*1.05=13.95g
