Hauv auerospace engineering, hydraulic nkhaus ua si ib lub luag haujlwm tseem ceeb hauv kev tswj lub zog thiab ruaj khov ntawm lub dav hlau lub davhlau tswj. Cov khoom siv no yuav tsum ua ke lub zog, xeb kuj, thiab kev ntseeg tau nyob hauv kev ntxhov siab. Titanium Qib 5 (Ti-6al-4V) tau tawm raws li cov khoom siv uas nyiam dua rau cov khoom no vim nws cov khoom siv zoo dua. Txawm li cas los xij, thaum nws los txog rau cov ncauj lus tom qab CNC machining, cov ntawv no cov txheej txheem nyuaj ntawm cov kev sib tw uas cov tuam ntxhab yuav tsum ua kom pom zoo.
Qhov tseem ceeb ntawm qhov chaw ua tiav hauv hydraulic nkhaus
Cov khoom zoo tsis yog ib qho kev ua kom zoo nkauj rau kev sib cav sib ceg hauv lub cav; Nws cuam tshuam ncaj qha cuam tshuam kev qaug zog, tiv thaiv kev tiv thaiv corrosion, thiab kev sib xyaw ua ke. Nyob rau hauv high {- kev nyuaj siab zones xws li hydraulic mounts, galling tsis zoo tuaj yeem ua rau muaj cov galling, galling, los yog kua to thaum siab.
Rau titanium alloys zoo li ti ...- {6v, ua tiav qhov nyuaj yog qhov nyuaj vim yog cov hlau cov kev ua kom nruj thiab muaj kev sib raug zoo. Yog tias tsis muaj kev tswj hwm kev ua tib zoo, post-machining cov txheej txheem tuaj yeem ua kev puas tsuaj rau ib feem ntau tshaj li lawv txhim kho nws.
Vim li cas Ti-6al-4V yog qhov nyuaj ua tiav
Titanium yog qhia txog nws txoj kev nyiam gall -}} qhov khoom siv los ntawm ib qho chaw sib hloov saum npoo av thiab ua rau lwm qhov hauv qab kev sib txhuam. Tus cwj pwm no ua rau lub sijhawm sib tsoo lossis sib tsoo, raws li cov hlau nrawm ua haujlwm - tawv thiab tawm tsam kev puas tsuaj ntxiv. Tsis tas li ntawd, nws txoj kev txom nyem thermal conductivity ua rau cua sov los tsim thaum lub sij hawm kho, nce kev pheej hmoo ntawm kev tshem tawm, ua rau muaj kev hloov pauv ntawm microloration.
Hauv cov tshuab hydraulic, txawm tias me me sab qab zib los yog seem sib txawv hauv kev sib txawv tuaj yeem ua rau muaj kev tsis ua haujlwm, tuaj yeem siv zog, lossis cov dej tsis ua haujlwm, lossis dej tsis ua haujlwm. Yog vim li cas titanium nto finishing tsis yog ib kauj ruam kom hniav zoo nkauj {{1} {{2 {tseem ceeb.
Cov Kev Xaiv Cov Chaw Ua Si thiab lawv cov kev lag luam - Offs
Cov Abrasive Polishing
Thaum ua tau zoo rau txhuas lossis hlau, cov pa abrasive polishing ntawm ti-6al-4V yuav tsum muaj cov txuj ci tshwj xeeb. Txheem log zoo li thauj tau sai sai, tsim cov chaw tsis ncaj. Pob zeb diamond abrasives lossis cov xov xwm ceramic siv hloov, feem ntau ntawm cov nrawm nrawm kom txo kev sib txhuam thiab cua sov tsim. Txawm li cas los xij, lub sijhawm no ntev ntev ntev.
Tshuaj lom neeg milling lossis etching
Tshuaj lom neeg cov kev kho cov tshuaj nto tuaj yeem txhim kho micro - smanium ua rau corrosion kuj ua rau nws tiv taus cov qauv etchant. Cov nyom, ntau -}}}}}}}}}}}}}}} Koj xav tau, uas thov kom muaj kev phom sij.
Anodizing (Hom II lossis Hom III)
Anodizing tuaj yeem txhim kho corrosion tsis kam thiab ntxiv cov tawv tawv tawv, tab sis nws tseem qhia txog kev hloov pauv. Cov txheej oxide yuav tsis raug teeb meem yog tias lub hauv paus nto tsis tau npaj kom zoo. Tsis tas li ntawd, anodized titanium hloov xim raws li oxide tuab, uas tej zaum yuav tsis tuaj yeem siv tau nyob rau hauv qee cov ntawv thov uas xav tau.
Khoov blasting
Rau matte tiav tag nrho, zoo iav lossis tej hub hlaws blasting yog siv. Txawm li cas los xij, cov txheej txheem no yuav tsum tau ua kom zoo. Ntau dhau siab lossis ntau tshaj tawm cov xov xwm tsis tsim nyog tuaj yeem tsim cov nplais lossis cov kab nrib xoo, ua rau lub ntsej muag ua haujlwm.
Passivation thiab tu
Post -}}}}} ua tiav kev tu yog tseem muaj kev txhawj xeeb. Cov seem los ntawm polishing lossis blasting yuav tsum tau muab tshem tawm tag nrho kom tsis txhob muaj galvanic cov tshuaj tiv thaiv thaum lub bracket tau sib dhos nrog lwm cov hlau hauv lub dav hlau. Titanium's oxide layer is self-forming but must be free of contaminants to ensure long-term integrity.
Cov tshooj lus los ntawm lub khw pem teb
Tseeb {- Cov ntaub ntawv thoob ntiaj teb feem ntau koom nrog kev ua haujlwm dua vim tias tsis raug npaj ua ntej. Piv txwv li, misjudged kauj ruam dhau ntawm ib qho tseem ceeb tseem ceeb tuaj yeem hloov qhov seem ntawm kev ua siab ntev dhau ntawm kev ua haujlwm ntawm kev tsim nyog. Qhov no yog qhov tseem ceeb tshaj plaws rau nruj- haum hydraulic nkhaus uas yuav tsum muaj kev cuam tshuam nrog cov actuator thiab cov kab ua kua.
Khw muag khoom muaj kev paub nrog cov xov xwm titanium feem ntau siv cov hybrid feem ntau siv cov hybrid {}} ntxhov siab dawb huv, thiab tswj cov tshuaj lom. Lawv kuj cia siab rau kev ua haujlwm tib neeg tshuaj xyuas nrog kev ntsuas saum npoo me thiab cov me me tshuaj xyuas, kom txhua lub bracket sib ntsib cov qauv hlua dav hlau.
Kaw kev xav
Raws li qhov xav tau nce rau kev sib tw sib dua, cov dav hlau muaj zog, titanium yuav nyob hauv tsev rau Aerospace kev tsim qauv. Txawm li cas los xij, xauv nws cov peev xwm tag nrho yuav tsum muaj kev nkag siab tob txog kev ua tiav nws kom raug. Rau qhov ua ke zoo li hydraulic nkhaus {{2} qhov twg muaj zog, haum, thiab cov txheej txheem sib dhos kom zoo yog qhov tseem ceeb li xaiv cov khoom nws tus kheej.
Cov neeg tsim khoom uas muaj txuj ci tshwj xeeb hauv titanium tsis yog nkag los txiav nws, tab sis yuav ua li cas ua tiav nws hauv txoj kev uas ua kom muaj kev ua lag luam thiab kev cai tswj tau. Nyob rau hauv aerospace, tsis muaj chaw cia siab.
