Segment Iav PM Sintered Part
Nyob rau hauv zus tau tej cov hmoov metallurgy zog, lub siab dua cov khoom ceev, siab dua nws lub cev thiab mechanical zog. Hauv lwm lo lus, qhov ceev thiab kev faib tawm ntawm cov hmoov hlau metallurgy iav cov khoom yuav txiav txim siab qhov ua tau zoo ntawm cov khoom. Yog li ntawd, thaum lub sij hawm debugging thiab nias cov txheej txheem ntawm hmoov metallurgy iav pwm, qhov ntom ntawm ib lub thawv yog ib qho yuav tsum tau kuaj. Hauv kev ntsuas qhov ceev, nws yuav tsum tau muab sau tseg tias cov qauv sib txawv thiab cov kev xav tau ntawm lub siab dawb paug yuav tsum tau kho qhov sib txawv.

Ua Tsis Zoo
Segment iav PM sintered ib feem hmoov metallurgy iav nyob rau hauv tus tsim ntawm cov txheej txheem nias yuav tsim compaction defects vim kev tsom xam ntawm ntau yam teeb meem thiab ua rau, uas ua rau lub scrapping ntawm hmoov metallurgy qhov chaw nyob rau hauv peb lub teb chaws. Yog li, dab tsi tsis xws luag feem ntau tshwm sim nyob rau hauv cov hmoov metallurgy iav compaction txheej txheem ntawm Segment iav PM sintered ib feem?
1. Lub compact ntom tsis ua raws li cov qauv tsim
Nyob rau hauv zus tau tej cov hmoov metallurgy zog, lub siab dua cov khoom ceev, siab dua nws lub cev thiab mechanical zog. Hauv lwm lo lus, qhov ceev thiab kev faib tawm ntawm cov hmoov hlau metallurgy iav cov khoom yuav txiav txim siab qhov ua tau zoo ntawm cov khoom. Yog li ntawd, thaum lub sij hawm debugging thiab nias cov txheej txheem ntawm hmoov metallurgy iav pwm, qhov ntom ntawm ib lub thawv yog ib qho yuav tsum tau kuaj. Hauv kev ntsuas qhov ceev, nws yuav tsum tau muab sau tseg tias cov qauv sib txawv thiab cov kev xav tau ntawm lub siab dawb paug yuav tsum tau kho qhov sib txawv.
2. Qhov loj ntawm cov qauv puag ncig tsis ua raws li qhov yuav tsum tau ua
Radial Dimension los yog suab tsis tsim nyog
2.1 Tej zaum yuav muaj teeb meem nrog pwm tsim lossis 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 cov pwm yuav raug muab pov tseg.
2.2 Tsis tsim nyog rau qhov sib txawv ntawm qhov kev taw qhia axial
Koj tuaj yeem kho thiab stabilize lub axial qhov ntev rau cov uas tsis yog-stepping cylindrical mis blanks, kho hmoov, hloov compactions los yog ncua sij hawm tuav, thiab lwm yam. Rau cov kauj ruam siab dawb paug, kho txoj hauj lwm ntawm kev sib koom tes tuag punch, hmoov ratio ntawm txhua qhov chaw nres tsheb. , khiav ceev ntawm lub floating tuag punch, thiab lwm yam, los hloov qhov siab ntawm cov kauj ruam.
3. Cov duab thiab txoj hauj lwm kam rau ua tsis kam
3.1 Kev Ncaj Ncees
Cov laj thawj rau kev ncaj ncees tawm ntawm kev ua siab ntev muaj xws li: tawm ntawm pwm ncaj, tsis sib luag ntom ntom ntawm lub cev ntsuab, tsis sib luag phab ntsa tuab ntawm lub cev ntsuab, thiab lwm yam.
3.2 Parallelism
Cov laj thawj rau kev tsis sib haum xeeb tsis sib xws muaj xws li: tawm ntawm qhov sib npaug ntawm cov pwm, cov hmoov tsis sib xws, thiab lwm yam.
3.3 Concentricity
Yog vim li cas rau qhov sib txawv ntawm coaxiality yog: qhov precision ntawm pwm yog tsawg dhau, qhov precision ntawm cov cuab yeej nias thiab cov cuab yeej siv tsawg, kev teeb tsa pwm tsis ua raws li qhov yuav tsum tau ua, thiab hnav khaub ncaws tsis sib xws.
Thaum cov hmoov ndlwg tus nqi tsim nyog, pwm raug raws li qhov tsim nyog, thiab cov cuab yeej nias thiab cov cuab yeej raug ua tau raws li qhov yuav tsum tau ua ntawm kev teeb tsa, cov duab thiab txoj hauj lwm kam rau ua yog feem ntau muaj feem xyuam rau qhov ntom ntom ntawm cov compact. 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 cov ntaub ntawv burr, poob npoo thiab fab, roughness thiab tawg yog tag nrho cov tsis xws luag nyob rau hauv peb compact tsim.
Cov saum toj no yog ib qho kev qhia txog qhov tsis xws luag tsim thaum lub sij hawm tsim cov txheej txheem ntawm hmoov metallurgy iav blanks. Muaj ntau yam tsis xws luag hauv cov hmoov metallurgy dawb paug txoj kev, tab sis lawv yuav ua rau cov khoom scrapping. Qhov tsis xws luag uas tsis yooj yim pom yog: tsis sib luag thiab tsis muaj qhov tawg, yog li kev tshwj xeeb yuav tsum tau them.
