Ntu Ib.Cov yam ntxwv ntawm cov phaj phaj
Ntu Ob.Technical xav tau rau cov phaj phaj
Ntu peb.Kev soj ntsuam ntawm kev siv tshuab ntawm cov phaj phaj
Ntu plaub.Kev xaiv cov khoom siv rau cov phaj phaj
Ntu tsib.Kev kho cua sov xav tau rau cov phaj phaj
Ntu 1. Cov yam ntxwv ntawm cov phaj phaj
Phaj qhov chaw yog qhov chaw nrog lub phaj tiaj tiaj raws li lub cev tseem ceeb, feem ntau muaj cov xov xov, qhov chaw txhawb nqa me me, qhov bearing qhov, sealing grooves, positioning keys thiab lwm qhov chaw.
Ntu 2. Kev xav tau ntawm cov phaj phaj
(1) Dimensional tolerance phaj qhov feem ntau yog muab faib ua ob pawg: ib qho yog siv los ua cov cuab yeej tshuaj xyuas thiab yog tus qauv rau txhua qhov ntsuas.Nws qhov kev txiav txim siab saum npoo yog siab, thiab qib siab siab feem ntau yog IT3 ~ IT4.Qhov yuav tsum tau yog txhawm rau txheeb xyuas qhov sib txawv ntawm cov khoom.Yam tsawg kawg 3 zaug;lwm yam ntawm qhov chaw yog siv nrog loj qhov chaw, thiab lawv qhov chaw tolerances feem ntau yuav tsum tau IT5 ~ IT6, uas yog ib theem siab tshaj qhov loj qhov chaw lawv phim.(2) Geometric tolerances Rau qhov flatness, verticality, thiab parallelism ntawm qhov chaw tseem ceeb xws li sab sauv thiab sab qis, sab nrauv, thiab tus thawj ntawm cov phaj phaj, feem ntau qhov yuam kev yuav tsum raug txwv rau qhov ntev ntawm qhov ntev.
(3) Nto roughness Cov txheej txheem ntawm lub phaj muaj qhov yuav tsum tau ua kom roughness, uas feem ntau txiav txim siab raws li kev ua tau zoo thiab kev lag luam ntawm kev ua, nrog rau kev siv qhov tseeb ntawm cov khoom.Qhov saum npoo roughness ntawm cov cuab yeej soj ntsuam dav hlau feem ntau yog Ra0.2 ~ 0.6μm, thiab qhov roughness ntawm qhov chaw dav hlau yog Ra0.6 ~ 1.0um.
Ntu 3. Kev soj ntsuam thev naus laus zis ntawm cov phaj phaj
Rau cov khoom uas xav tau ntau dua precision, roughing thiab xov yuav tsum tau ua tiav nyias los xyuas kom meej qhov zoo ntawm cov khoom.Kev ua tiav ntawm cov phaj phaj feem ntau tuaj yeem muab faib ua peb theem: milling ntxhib ( ntxhib milling ntawm lub ntsej muag kawg, boring ntxhib), semi-tiav milling (semi-tiav milling ntawm lub ntsej muag kawg, semi-zoo tho txawv, drilling thiab tapping ntawm txhua qhov threaded), nplua milling thiab zoo tho txawv, qee zaum txhawm rau ua kom tiav qhov zoo ntawm qhov chaw thiab qhov chaw tiaj tus, yuav tsum muaj txheej txheem sib tsoo.
Ntu 4. Kev xaiv cov khoom siv rau cov phaj phaj
(1) Cov khoom siv ntawm cov phaj phaj phaj feem ntau yog ua los ntawm cov hlau cam.Rau daim hlau uas yuav tsum tau muaj siab precision thiab zoo rigidity, 45 steel, 40Cr, los yog ductile hlau yuav siv tau;rau kev kub ceev, hnyav-ua haujlwm daim hlau, cov pa roj carbon tsawg xws li 20CrMnTi20Mn2B, 20Cr, lossis 38CrMoAI ammonia steel tuaj yeem siv.
(2) Cov seem ntawm cov phaj tom qab cua sov thiab forging ntawm blanks xws li 45 steel, cov txheej txheem fiber ntau ntawm cov hlau tuaj yeem sib npaug sib npaug ntawm qhov chaw kom tau txais lub zog tensile siab dua, khoov lub zog thiab lub zog torsion.Castings tuaj yeem siv rau cov phaj loj lossis cov phaj nrog cov qauv tsim.
Ntu 5. Kev kho cua sov yuav tsum tau ua rau cov phaj phaj
1) Ua ntej ua tiav, forging roughness yuav tsum normalized los yog annealed los ua kom cov nplej sab hauv ntawm cov hlau, tshem tawm cov kev ntxhov siab, txo cov khoom hardness, thiab txhim kho cov txheej txheem.
2) quenching thiab tempering feem ntau yog npaj tom qab ntxhib milling thiab ua ntej semi-tiav milling kom tau txais cov khoom zoo txhua yam.
3) Nto quenching feem ntau yog npaj ua ntej ua tiav, kom lub zos deformation los ntawm quenching tuaj yeem kho.4) Cov phaj uas muaj qhov yuav tsum tau muaj siab yuav tsum tau txais kev kho mob qis qis tom qab kev sib tsoo hauv zos lossis sib tsoo ntxhib.
