Kev txiav txim siab rau kev xaiv cov khoom hauv Precision Mechanical Component Manufacturing
Kev txiav txim siab raws li kev ua haujlwm pabcuam
Lub zog thiab Hardness: Qhov kev xaiv yog raws li cov khoom siv ib puag ncig kev pabcuam thiab thauj khoom -cov kev cai. Piv txwv li, lub cav crankshafts, uas ua rau muaj kev hloov pauv tseem ceeb, feem ntau yog ua los ntawm siab - lub zog alloy steels xws li 40Cr los tiv thaiv deformation thiab tawg nyob rau hauv txoj kev ntev - lub sij hawm kev ntxhov siab. Hauv qhov sib piv, cov cuab yeej txiav rau kev ua haujlwm siab - cov ntaub ntawv hardness feem ntau yog tsim los ntawm cov cemented carbides, uas muaj cov hardness siab heev thiab hnav tsis kam, ua kom muaj kev txiav ntse.
Hnav Resistance: Rau cov khoom siv ua haujlwm hauv qhov chaw sib txhuam, xws li lub zog thiab cov kabmob, cov khoom siv nrog kev hnav zoo yog qhov tseem ceeb. Piv txwv li, cov iav hauv tsheb sib kis feem ntau yog ua los ntawm cov hlau carburizing zoo li 20CrMnTi. Tom qab carburizing thiab quenching, cov iav no ua tiav qhov tawv tawv thiab hnav tsis kam, txo qis hnav thaum kis tau tus mob thiab ncua kev pab cuam lub neej.
Corrosion Resistance: Cheebtsam raug cov av noo, acidic, lossis alkaline ib puag ncig, xws li li qub thiab cov kav dej hauv cov khoom siv tshuaj, yuav tsum muaj cov khoom siv tiv thaiv corrosion-. Piv txwv li, 316L stainless hlau, nrog nws zoo heev corrosion kuj thiab tsis kam mus rau intergranular corrosion, muaj peev xwm tuav ruaj khov kev kawm nyob rau hauv hnyav tshuaj ib puag ncig.
Thermal stability: Cov khoom siv ua haujlwm hauv siab - qhov kub thiab txias, xws li turbine blades hauv aero- cav, xav tau cov ntaub ntawv zoo thermal stability. Nickel-raws li superalloys, paub txog lawv qhov siab tshaj - kub lub zog, oxidation tsis kam, thiab tsis kam mus rau kub corrosion, feem ntau yog siv rau turbine hniav. Cov ntaub ntawv no tuav lawv cov duab thiab kev ua haujlwm ntawm qhov kub thiab txias, ua kom lub cev ua haujlwm ntawm lub cav.
Kev txiav txim siab raws li Machinability
Txiav Performance: Txhawm rau txhim kho machining efficiency thiab zoo, cov ntaub ntawv yuav tsum muaj cov khoom zoo. Piv txwv li, dawb- txiav steels (xws li Y12 thiab Y15) yog txhim kho los ntawm kev ntxiv cov ntsiab lus xws li sulfur thiab txhuas, uas txo cov cuab yeej hnav, txiav quab yuam, thiab txhim kho nti tawg thaum lub sij hawm machining, yog li ua kom muaj txiaj ntsig zoo thiab qhov chaw zoo.
Forging Performance: Rau cov khoom uas yuav tsum tau forging, cov khoom forgeability yog qhov tseem ceeb. Piv txwv li, aluminium alloy 6061 muaj qhov zoo forgeability thiab tuaj yeem yooj yim deformed nyob rau hauv lub xeev kub los ua complex -zoo li tus Cheebtsam nrog txhim kho txhua yam khoom tom qab forging.
Vuam Performance: Thaum cov khoom yuav tsum tau sib sau ua ke los ntawm vuam, cov ntaub ntawv uas muaj weldability zoo yuav tsum tau xaiv. Piv txwv li, Q235 steel muaj cov khoom siv vuam zoo heev thiab tsis tshua muaj kev puas tsuaj xws li tawg thiab porosity thaum vuam, ua kom lub zog thiab sealability ntawm cov pob qij txha welded. Nws yog dav siv nyob rau hauv ntau yam welded structural Cheebtsam.
Kev kho cua sov ua haujlwm: Ntau cov khoom siv kho tshuab precision xav tau kev kho cua sov kom ua tiav cov khoom xav tau. Piv txwv li, 45 steel tuaj yeem ua tiav kev sib xyaw ua ke zoo ntawm lub zog thiab lub zog los ntawm kev quenching thiab tempering. Txawm li cas los xij, kev tswj hwm nruj ntawm kev kho cua sov yog tsim nyog los tiv thaiv kev deformation thiab tawg.
Kev txiav txim siab raws li tus nqi
Tus nqi khoom siv: Nyob rau hauv cov kev txwv ntawm kev sib ntsib cov kev pab cuam thiab machining yuav tsum tau, cov khoom nqi yog ib qho tseem ceeb. Rau cov khoom siv kho tshuab dav dav uas xav tau kev ua haujlwm qis dua, xws li cov khoom siv kho tshuab thiab cov vaj tsev, qis dua - cov nqi carbon steels xws li Q235 tuaj yeem siv. Hauv qhov sib piv, rau cov khoom tseem ceeb hauv kev ua haujlwm siab -, xws li aerospace qhov chaw, siab - cov ntaub ntawv ua haujlwm tshwj xeeb yog tsim nyog txawm tias lawv cov nqi siab.
Machining Nqi: Cov khoom sib txawv muaj qhov sib txawv machining nyuaj thiab cov nqi. High -cov ntaub ntawv ua tau zoo xws li titanium alloys, txawm tias zoo dua hauv kev ua tau zoo, yog qhov nyuaj thiab kim rau tshuab. Thaum xaiv cov ntaub ntawv, ob qho tib si cov khoom siv thiab cov nqi machining yuav tsum raug ntsuas kom tiav. Rau qhov ntim ntau lawm, tus nqi - cov ntaub ntawv zoo nrog cov txheej txheem machining zoo tuaj yeem txo cov nqi tag nrho.
Lub neej-Cycle Cost: Xaiv cov ntaub ntawv uas muaj kev ua tau zoo thiab kev pab lub neej ntev yuav muaj tus nqi pib dua tab sis tuaj yeem txo qhov kev hloov zaus thiab cov nqi kho lub sij hawm, txo lub neej tag nrho - mus txog tus nqi. Piv txwv li, kev siv cov khoom zoo hauv - cov khoom zoo hauv cov khoom loj - cov khoom siv loj tuaj yeem muaj tus nqi yuav ntau dua tab sis tuaj yeem ncua sijhawm txij nkawm thiab txhim kho kev ua haujlwm zoo, ua rau cov nqi qis dua.
Lwm yam kev xav
Khoom Muaj: Ua ntej cov ntaub ntawv uas yooj yim muaj nyob rau hauv kev ua lag luam kom ntseeg tau tias kev tsim khoom tsis tu ncua. Cov ntaub ntawv tshwj xeeb, xws li qee cov hlau tsis tshua muaj hlau, tej zaum yuav muaj cov khoom siv tsawg thiab cov khoom siv ntev, cuam tshuam rau cov sij hawm tsim khoom. Thaum xaiv cov ntaub ntawv, xav txog lawv qhov muaj thiab xaiv cov kev xaiv uas yooj yim dua thiab ruaj khov hauv cov khoom.
Environmental Requirements: Nrog rau kev paub txog ib puag ncig, kev ua haujlwm ib puag ncig ntawm cov ntaub ntawv tseem ceeb dua. Thaum xaiv cov khoom, xav txog lawv qhov cuam tshuam rau ib puag ncig thaum tsim khoom, siv, thiab pov tseg. Piv txwv li, zam cov khoom uas muaj teeb meem xws li txhuas, mercury, thiab cadmium, thiab xaiv cov khoom siv rov ua dua kom txo tau cov pa phem ib puag ncig.
Standardization thiab Generalization ntawm cov ntaub ntawv: Txhawm rau txhim kho kev tsim, tsim khoom, thiab kev saib xyuas ntawm cov khoom siv, cov khoom siv nrog cov txheej txheem siab thiab dav dav yuav tsum nyiam. Qhov no txo qhov ntau thiab tsawg ntawm cov ntaub ntawv, txo cov nqi khoom muag, thiab txhim kho kev tsim khoom. Cov ntaub ntawv txheem kuj tseem muaj cov txheej txheem ua tiav thiab cov qauv zoo, uas pab ua kom cov khoom zoo.
