Dab tsi tsis zoo feem ntau tshwm sim hauv cov txheej txheem ntawm cov hmoov metallurgy compact?

Nyob rau hauv cov txheej txheem ntawm cov hmoov metallurgy compaction, yuav muaj qhov tsis xws luag nyob rau hauv lub compact vim muaj ntau yam, ua rau lub scrapping ntawm hmoov metallurgy qhov chaw. Yog li, dab tsi tsis xws luag feem ntau tshwm sim hauv cov txheej txheem ntawm cov hmoov metallurgy compact?

1. Lub compact ntom tsis ua raws li cov qauv tsim

Hauv kev tsim khoom ntawmhmoov metallurgyqhov chaw, qhov siab dua ntawm cov khoom siv, qhov siab dua lawv lub cev thiab cov khoom siv kho tshuab. Nyob rau hauv lwm yam lus, lub compacts ceev thiab kev faib ntawm cov hmoov metallurgy qhov chaw yuav txiav txim seb lub zog ntawm cov khoom. Yog li ntawd, nyob rau hauv tus txheej txheem ntawm hmoov metallurgy pwm debugging thiab nias, qhov ceev ntawm lub compact yuav tsum tau kuaj. Thaum kuaj pom qhov ntom ntom, nws yuav tsum tau muab sau tseg tias cov compacts nrog cov qauv sib txawv thiab cov kev xav tau yuav tsum tau kho sib txawv.

2. Qhov loj ntawm lub compact tsis ua raws li qhov yuav tsum tau ua

2.1 Lub radial dimension tsis tsim nyog los yog qhov sib nrug ntawm qhov tsis tsim nyog

Tej zaum yuav muaj teeb meem nrog pwm tsim lossis kev tsim khoom. Yog tias qhov yuam kev tuaj yeem raug tshem tawm los ntawm kev kho cov txheej txheem (uas yog, los ntawm kev kho cov hmoov sib xyaw, compact ntom, txheej txheem sintering, thiab lwm yam). Nws kuj tuaj yeem kho tau, txwv tsis pub tsuas yog khawb cov pwm.

2.2 Lub axial dimension tsis tsim nyog

Rau cov uas tsis yog stepped cylindrical compacts, axial qhov ntev tuaj yeem hloov kho thiab ruaj khov los ntawm kev kho cov hmoov thauj khoom, hloov lub siab nias lossis ncua lub sijhawm tuav. Rau cov kauj ruam dawb paug, cov kauj ruam qhov siab tuaj yeem hloov pauv los ntawm kev kho txoj haujlwm ntawm kev sib koom ua ke ntawm cov punch tuag, cov hmoov thauj khoom sib piv ntawm txhua lub teeb, thiab kev khiav ceev ntawm cov punch tuag.

3. Geometric kam rau ua tsis kam

3.1 Kev Ncaj Ncees

Cov laj thawj rau kev tawm ntawm kev kam rau siab ncaj yog: tawm ntawm kev kam rau siab ncaj ntawm kev tuag, tsis sib npaug ntawm qhov sib npaug ntawm cov compact, tsis sib xws phab ntsa thickness ntawm compact, thiab lwm yam.

3.2 Parallelism

Qhov ua rau tawm ntawm kev kam rau siab parallelism yog: tawm ntawm kev ua siab ntev parallelism ntawm kev tuag, tsis sib xws hmoov loading, thiab lwm yam.

3.3 Coaxiality

Cov laj thawj rau coaxiality tawm ntawm kev kam rau siab muaj xws li: tawm ntawm kev kam rau siab ntawm pwm precision, tsis tshua muaj precision ntawm cov cuab yeej nias thiab cov cuab yeej siv, kev tsim pwm tsis tsim nyog, hnav tsis sib xws, thiab lwm yam.

Thaum cov hmoov ndlwg tus nqi tsim nyog, cov pwm raug ua tau raws li qhov yuav tsum tau ua, thiab cov cuab yeej nias thiab cov cuab yeej raug ua tau raws li qhov yuav tsum tau ua, daim ntawv thiab txoj hauj lwm kam rau ua yog feem ntau cuam tshuam nrog qhov ntom ntom ntom ntom ntom ntom ntom. Thaum txoj kev nias tau txiav txim siab, qhov tseem ceeb tshaj tawm ntawm cov kev cog lus yog ncaj qha cuam tshuam nrog cov hmoov sau cov hmoov zoo.

4. Cov tsos mob tsis tsim nyog

High roughness, ntau burr, ntug thiab ces kaum poob, galling thiab tawg yog cov tsos mob ntawm compacts.

Cov saum toj no yog ib qho kev qhia txog qhov tsis xws luag tsim nyob rau hauv cov txheej txheem ntawm hmoov metallurgy compact. Muaj ntau yam tsis xws luag nyob rau hauv hmoov metallurgy compact, tab sis qhov tsis yooj yim nrhiav tau yog: tsis yooj yim ntom thiab sib nraus tawg, yog li peb yuav tsum them nyiaj tshwj xeeb rau lawv.
