Cov kev ua tau zoo polishing ntawmyas mouldS cuam tshuam los ntawm ntau yam ntawm cov ntsiab lus, uas tuaj yeem suav tau rau hauv cov pawg tseem ceeb hauv qab no:
1. Khoom siv
Steel zoo: lub hardness, purity thiab kev sib xyaw ntawm cov khoom yog qhov tseem ceeb heev. High-hardness steel yog ntau hnav-resistant tab sis nyuaj rau txhuam; Impurities lossis pores tuaj yeem yooj yim coj mus rau saum npoo degrom.
Txheej txheem kho cua sov: kev kho cua sov yuav ua rau muaj kev nyuaj siab tsis sib xws, txheej txheem kev ntxhov siab lossis cov txiv kab ntxwv ua rau cov txiv kab ntxwv peel tshwm sim lossis micro-tawg.
2. Kev Tsim Kho Cov Txheej Txheem
Cov txheej tawv tawv tsim los ntawm Edm (hais txog {{{} μm) yuav tsum tau muab tshem tawm los ntawm kev sib tsoo los yog acid etching, txwv tsis pub nws yooj yim rau pitting tom qab pOLISHING.
Machining cov cim: sib sib zog nqus riam los ntawm milling lossis sib tsoo yuav tsum tau kho ua ntej polishing, txwv tsis pub nws nyuaj rau kev tshem tawm tag nrho.
3. Cov txheej txheem polishing
Cov kauj ruam thiab cov cuab yeej: Ua raws cov txheej txheem los ntawm ntxhib rau nplua (piv txwv li 400 # → 1500 # Sandpaper), txhua kauj ruam xav tau kom tshem tawm cov kab dhau yav dhau los.
Polishing Nruab Nrab: Xaiv tsis raug ntawm kev sib tsoo siv cov tshuaj sib tsoo loj (xws li kev ua kom ntxov ua kom zoo nkauj zoo nkauj) tuaj yeem ua rau muaj peev xwm lossis tsis sib luag.
Kev tswj qhov kub thiab txias: kev kub ntxhov hauv zos yuav ua rau cov khoom muag los soften lossis oxidize, cuam tshuam rau qhov sib xws.
4. Mould Tsim
Geometric complexity: thaj chaw nrog cov ces kaum sib sib zog nqus lossis cov ces kaum sib sib zog nqus yog qhov nyuaj rau tusyees polish, thiab yuav tsum tau txiav txim siab thaum lub sijhawm tsim qauv.
Parting kab thiab ntxig qauv: sib koom ua ke yooj yim los tsim tsis ncaj polishing, xav tau kev kho mob tshwj xeeb.
5. Nto Nto Pretricatment
Kev nyiam huv: Roj, xeb lossis oxide yuav tsum tau muab tshem tawm kiag li los ntawm kev tuaj yeem hle los yog bandblasting, txwv tsis pub nws yuav cuam tshuam rau cov nyhuv polishing.
Welding kho: qhov nyuaj txawv ntawm lub vuam cov khoom siv thiab cov substrate yuav tsum tau tshem tawm los ntawm kev kho tempering (xws li 300 degree × 2h).
6. Tib neeg
Kev txawj tuav cov kev txawj ntse: kev tsis paub qab yuav ua rau hla kev (xws li tsis polishing (cov khoom siv tshem tawm> {}}. 01 hli).
Yuav tsum tau tshuaj xyuas zoo: Kev tshuaj xyuas lub sijhawm tiag tiag yuav tsum siv ib qho 1 {{}} x lub zog loj lossis ntsuas qis dua lossis sib npaug rau 0.025μm).
7. Ib puag ncig tswj
Kev nyiam huv: Nws yuav tsum tau ua haujlwm nyob rau hauv ib chav rhiav dawb yog ISO chav kawm 6 (chav kawm 1000) kom tsis txhob muaj cov lus.
Qhov kub thiab cov av noo: 23 ± 2 degree c thiab {40-60%}}% pom zoo kom tiv thaiv cov roj av xeb.
8. AUXILIA SYO PAB
Polishing tshuab qhov tseeb: ntxaiv radial radout yuav tsum <{}}.}}}}}}}}.
Fixture tsim: nws yog qhov tsim nyog los xyuas kom meej tias qhov ua haujlwm ruaj khov thiab zam kev ripples tshwm sim los ntawm kev co (amplitude <2μm).
9. Cov txheej txheem tom qab kev kho mob
Kev tu kom huv: Siv cov kuab tshuaj nruab nrab (PH6. {5-7. 5) ntawm 40kHz rau 10 feeb los tshem tawm cov kev cai polishing.
Anti-xeb kev kho mob: tshuaj tsuag roj los tiv thaiv xeb (VCI) lossis nitrogen cia kom tiv thaiv oxidation thaum lub sijhawm khaws cia.
