Kev ua haujlwm tsis yog txheej txheembronze bushingskoom nrog ntau cov kauj ruam tshwj xeeb los xyuas kom meej tias lawv ua tau raws li qhov xav tau tshwj xeeb thiab cov qauv kev ua haujlwm.
txheej txheem technology:
1. Kev xaiv khoom siv:
- Bronze Alloy Xaiv:Kev xaiv ntawm cov hlau bronze uas tsim nyog (piv txwv li, SAE 660, C93200, C95400) yog qhov tseem ceeb. Txhua alloy muaj cov khoom sib txawv xws li hardness, lub zog, hnav tsis kam, thiab machinability.
- Raw Material Quality:Xyuas kom cov khoom siv raw tsis muaj impurities thiab tsis xws luag. Qhov no tuaj yeem raug txheeb xyuas los ntawm cov ntaub ntawv pov thawj thiab kev tshuaj xyuas.
2. Tsim thiab Specifications:
- Custom Design:Tsis yog tus qauv bushings xav tau cov qauv tsim tshwj xeeb. Cov no muaj xws li qhov ntev, kam rau ua, nto tiav, thiab cov yam ntxwv tshwj xeeb (xws li, flanges, grooves, lubrication qhov).
- Kev kos duab:Tsim cov duab kos duab ntxaws ntxaws thiab CAD qauv uas qhia txog txhua yam tsim nyog thiab cov yam ntxwv.
3. Casting thiab Forging:
- Casting:Rau cov bushings loj los yog complex, xuab zeb casting los yog centrifugal casting txoj kev yuav siv tau. Xyuas kom zoo ib yam txias kom tsis txhob muaj kev ntxhov siab thiab tsis xws luag.
- Forging:Rau cov bushings me me los yog cov uas xav tau lub zog siab, forging yuav raug siv los kho cov qauv nplej thiab txhim kho cov khoom siv kho tshuab.
4. Machining:
- Tig thiab tho txawv:CNC lathes thiab tshuab tho txawv yog siv los ua kom tiav qhov xav tau sab hauv thiab sab nraud.
- Milling:Rau cov duab nyuaj lossis cov yam ntxwv ntxiv xws li keyways thiab slots, CNC milling tshuab tau ua haujlwm.
- Drilling:Qhov tseeb drilling rau lubrication qhov thiab lwm yam kev cai nta.
- Xov xov:Yog hais tias lub bushing yuav tsum tau threaded seem, precision threading hauj lwm yog ua.
5. Kev kho cua sov:
- Stress Relieving:Cov txheej txheem kho cua sov xws li annealing lossis kev ntxhov siab tuaj yeem siv los txo cov kev ntxhov siab sab hauv thiab txhim kho machinability.
- Hardening:Qee cov bronze alloys tuaj yeem ua kom tawv tawv los txhim kho hnav tsis kam, tab sis qhov no tsis tshua muaj rau bushings.
6. Ua tiav:
- Sib tsoo thiab polishing:Precision sib tsoo kom ua tiav qhov yuav tsum tau ua tiav thiab qhov tseeb qhov tseeb.
- Txheej Txheej:Siv cov coatings (piv txwv li, PTFE, graphite) kom txo tau kev sib txhuam thiab txhim khu kev hnav tsis kam, yog tias tau teev tseg.
7. Kev Tswj Xyuas Zoo:
- Dimensional soj ntsuam:Siv cov cuab yeej ntsuas qhov tseeb (micrometers, calipers, CMM) txhawm rau txheeb xyuas qhov ntev thiab qhov ntev.
- Cov khoom siv kuaj:Ua cov kev ntsuam xyuas rau hardness, tensile lub zog, thiab tshuaj muaj pes tsawg leeg los xyuas kom meej cov khoom conformity.
- Kev Xeem Tsis Muaj Kev Ua Phem (NDT):Cov txheej txheem xws li kev kuaj ultrasonic lossis tshuaj ntsuam xyuas cov xim tuaj yeem siv los txheeb xyuas cov teeb meem sab hauv thiab saum npoo.
8. Assembly thiab Fitment:
- Interference Fit:Xyuas kom muaj kev cuam tshuam zoo ntawm lub bushing thiab vaj tse los yog ncej kom tsis txhob txav mus los thiab hnav.
- Lubrication:Xyuas kom meej tias tsim nyog lubrication channels los yog grooves muaj nyob rau cov kev xav tau kev ua hauj lwm.
Technical Requirements:
- Dimensional Tolerances:Yuav tsum tau ua nruj me ntsis raws li cov qauv tsim los xyuas kom haum thiab ua haujlwm.
- Nto tiav:Ua kom tiav qhov yuav tsum tau muaj qhov roughness (piv txwv li, Ra tus nqi) kom ntseeg tau tias kev ua haujlwm du thiab txo kev sib txhuam.
- Khoom siv:Xyuas kom tseeb tias cov khoom ua tau raws li cov khoom siv kho tshuab, suav nrog hardness, tensile zog, thiab elongation.
- Thaum tshav kub kub kho Certification:Yog tias tsim nyog, muab ntawv pov thawj tias bushing tau dhau los ua cov txheej txheem kho cua sov uas tau teev tseg.
- Kev Tshawb Fawb Tshaj Tawm:Khaws cov ntaub ntawv txheeb xyuas kom ntxaws txog qhov raug, qhov chaw tiav, thiab cov khoom siv.
- Ua raws li cov qauv:Xyuas kom cov bushings ua raws li cov qauv kev lag luam (piv txwv li, ASTM, SAE, ISO) rau cov khoom siv thiab kev tsim khoom.
Los ntawm kev ua raws li cov thev naus laus zis thiab cov kev xav tau, cov khoom siv tooj liab tsis yog tus qauv tuaj yeem tsim kom tau raws li cov lus qhia meej thiab ua tau zoo hauv lawv cov ntawv thov.
