Lub tog raj kheej ua tshuab
Raws li kev soj ntsuam saum toj no, tom qab kev txhim kho thiab txhim kho, txoj kev siv tshuab tseem ceeb ntawm titanium alloy lub tog raj kheej tau txiav txim siab raws li hauv qab no:
Npliag → ntxhib tig ntawm ob qho kawg → ntxhib milling ntawm cov duab → tho qhov loj kawg → ua tiav ntawm lub voj voog sab nrauv → ntxhib tho txawv → tiav tho txawv → ntxhib honing ntawm puab lub qhov → tho thiab tho → tho txawv groove → tig nozzle → tho txawv me me kawg sab hauv qhov → nruab nrab soj ntsuam → tiav milling ntawm cov duab → tiav tho txawv, zawj thiab Xov → milling ntawm xov thiab milling groove → drilling ntawm xauv xov lub qhov → tiav honing ntawm puab lub qhov → deburring → fluorescence tshuaj xyuas → zaum kawg tshuaj ntsuam
1 .Semi-finishing ntawm puab lub qhov
Vim qhov kev txwv ntawm lub tog raj kheej qauv, semi-tiav ntawm lub puab lub qhov yog xaiv los ntawm txoj kev tig. Lub fixture siv rau kev ua khoom belongs rau "ib nrab-pobzeb" qauv, raws li qhia nyob rau hauv daim duab 2. Qhov sib txuam clearance ntawm lub fixture thiab ib feem yog tswj nyob rau hauv 0.02mm los txo qhov deformation ntawm qhov chaw.
Titanium alloy muaj ib tug me me elastic modulus, uas yog heev yooj yim los tsim loj deformation thiab distortion thaum lub sij hawm ua, thiab cov neeg ua hauj lwm tsis yog ib qho yooj yim los lav. Yog li ntawd, thaum siv lub clamp, lub clamping quab yuam yuav tsum tau tswj. Thaum xauv lub clamping bolts ntawm lub clamp, lub zog yuav tsum sib xws thiab tsim nyog. Nws yuav tsum tsis txhob loj dhau los tiv thaiv lub cylinder nyias-walled los ntawm deformed los ntawm lub siab; nws yuav tsum tsis txhob me me dhau los tiv thaiv cov khoom los ntawm kev clamped loosely thiab txav mus rau lub sijhawm ua haujlwm, cuam tshuam rau qhov tseeb, lossis cov khoom los ntawm ya tawm thiab ua rau neeg raug mob thaum ua haujlwm. Tom qab lub tog raj kheej yog clamped, txiav yuav tsum tau ua nyob rau hauv ntau zaus thaum lub sij hawm ua kom txo cov txiav quab yuam, tiv thaiv lub tog raj kheej los ntawm deformed thaum lub sij hawm clamping thiab rebound deformation, thiab xyuas kom meej cov kev ua tau zoo ntawm lub puab lub qhov.
2. Honing ntawm puab lub qhov
Kev sib tsoo kev ua tau zoo ntawm titanium alloy tsis zoo. Qhov no yog vim hais tias titanium alloy muaj lub zog siab thiab tawv, muaj zog tshuaj lom neeg ua haujlwm ntawm qhov kub thiab txias, deterioration ntawm tej yam kev mob, thiab yooj yim tiam ntawm kev sib tsoo microcracks thiab sib tsoo kub thaum sib tsoo. Honing txoj kev yog siv rau qhov kawg ntawm lub puab qhov ntawm cov khoom.
Honing yog qhov tseem ceeb tshwj xeeb ntawm kev sib tsoo nrog kev txiav ceev thiab cov cua txias zoo. Nws yog qhov qis-ceev thiab loj-qhov chaw sib cuag tiav. Tom qab sau cov ntaub ntawv los ntawm ntau qhov chaw thiab ua cov kev ntsuam xyuas rov qab, nws tau txiav txim siab tias tom qab lub qhov hauv lub tog raj kheej tau zoo tig, lub puab lub qhov yog ntxhib-honed thiab lub puab lub qhov zoo-honed los xyuas kom meej lub puab qhov zoo zawj. Yog li ntawd, cov txheej txheem kev npaj yuav tsum tsis tsuas yog xyuas kom meej cov kev ua tau zoo, tab sis kuj xav txog kev ua hauj lwm efficiency. Cov txheej txheem txheej txheem npaj rau thawj qhov ntxhib-tig rau sab hauv thiab sab nrauv ntawm qhov kawg ntawm qhov me me nrog rau qhov sib khi zawj ntawm CNC tshuab dhos, thiab tom qab ntawd siv cov khoom sib xyaw ua ke kom zoo-dhau lub qhov thiab qhov sib khi, thiab tig. lub taub hau me me xov txheej txheem.
3.CNC machining ntawm me kawg xov
Raws li cov qauv tsim, qhov tseeb ntawm cov xov me me ntawm lub tog raj kheej yog qib 6,
thiab qhov khiav mus rau qhov siv yog 0.1mm. Xav txog cov xov raug thiab kev ua tau zoo, txoj kev xa xov yog xaiv. Ntawm cov khoom siv sib xyaw ua ke, qhov me me kawg sab hauv lub qhov thiab cov txheej txheem sealing groove yog cov tshuab zoo, thiab cov xov me me yog tig tib lub sijhawm. Tom qab ua tiav, cov xov muaj qhov raug siab, ruaj khov zoo thiab ua haujlwm siab.
Feem ntau, titanium cylinders ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv ntau qhov chaw siab kawg vim lawv lub cev thiab tshuaj lom neeg tshwj xeeb. Txawm hais tias tus nqi siab thiab kev sib tw ua tiav, lawv cov kev ua tau zoo tshaj plaws ua rau lawv cov khoom xaiv rau ntau daim ntawv thov tseem ceeb.
