Ua ntej, qhov chaw seem ntawm kev tshuaj ntsuam xyuas
1, kev tshuaj ntsuam xyuas
So lub qhov npog ntawm txheej hau nrog huv qhov ncauj. Tus neeg kuaj dej yuav tsum hnav cov hnab looj tes kov lub nplhaib ntawm lub thwj rau ntawm txoj kev thim ntawm txoj hlua. Txoj kev soj ntsuam no yog nyob ntawm qhov kev paub ntawm tus kws ntsuam xyuas. Yog tias tsim nyog, roj zeb tuaj yeem siv tau polish thiab tshawb xyuas tias tsam tsam tsam tsam tsam, tab sis txoj kev no yog ib hom kev paub ceev ceev.
2, roj zeb polishing
2.1. Ua ntej ntxuav lub qhov npog ntawm txheej hau nrog huv qhov muag, ces txhuam nrog roj zeb (20 × 20 × 100mm lossis loj dua), qhov chaw nrog arc thiab nyuaj rau ntaus nrog ib tus me me roj zeb. (Piv txwv li: 8 × 100mm semi-circular oilstone)
2.2, qhov xaiv ntawm cov roj particle loj yog nyob ntawm cov kev mob npoo (xws li roughness, galvanizing, etc.). Pib nrog cov nplua tooj zoo. Cov kev taw qhia ntawm lub pob zeb sib tsoo yog nyob rau hauv qhov kev coj mus ntev, thiab nws haum zoo nrog lub nplhaib ntawm qhov chaw stamping, thiab qee qhov chaw ntxiv tau ntxiv rau sab kev sib tsoo.
3. Polishing ntawm cov ntaub qhwv to taub
So lub qhov npog ntawm txheej hau nrog huv qhov ncauj. Qhov nplais ntawm qhov chaw stamping yog xuab zeb mus rau tag nrho cov nplaim hauv qhov kev cob qhia los ntawm cov xuab zeb yooj yooj yim, thiab txhua yam pitting thiab kev qis qis tau yooj yim.
4, roj xyuas
So lub qhov npog ntawm txheej hau nrog huv qhov ncauj. Lub txhuam kom huv yog siv qhov sib npaug ntawm sab nraud ntawm lub thwj cim rau hauv ib qho kev coj. Cov roj ntim ntawm cov roj yuav muab tso rau hauv lub zog uas muaj zog tuaj yeem pib tshawb xyuas thiab cov stampings tso rau hauv lub cev. Hom no ua tau yooj yim txua me me pittings, ponds, thiab corrugations ntawm stampings.
5, kev kuaj xyuas pom kev
Nrig txog kev ntsuam xyuas yog siv rau qhov nto thiab cov teeb meem ntawm qhov tsis muaj tseeb ntawm cov khoom tsim tawm
6, tshuaj ntsuam xyuas
Cov stampings raug muab tso rau hauv qhov kev ntsuas xyuas, thiab cov stampings raug kuaj xyuas raws li txoj cai yuav tsum tau ua ntawm kev kuaj xyuas.
Qhov ob, qhov chaw seem ntawm kev txhim kho qhov kev ntsuam xyuas txoj cai

177. Cov khoom siv kho hluav taws xob qhia koj mus yuav khoom kho vajtse
Ruaj ntseg yog qhov feem ntau inconspicuous nyob rau hauv qhov kev tsim kho tshiab, tab sis cov ntaub ntawv tseem pheej lossis cov khoom.
Txawm hais tias qhov kho vajtse yog me me, cov nyhuv yog loj heev. Yog li yuav ua li cas xaiv yog qhov tseem ceeb heev.
Nyob hauv tsev kho kom zoo nkauj tam sim no, qhov kev xaiv ntawm qhov kho vaj tse yog qhov zoo tshaj plaws rau cov qauv, ib txwm zoo nkauj, tab sis nyob rau hauv cov tswv yim siv, tus tswv tsev feem ntau ignore qhov tseem ceeb ntawm kev siv cov cuab yeej kho mob.
Txawm hais tias qee yam ntawm cov khoom siv tseem ceeb yog siv zoo heev, yog tias tsis muaj kev kho vaj tse zoo kom phim, nws yuav cuam tshuam cov kev ua haujlwm ntawm rooj tog thiab qhov rooj thiab qhov rais. Tiag tiag, nws yuav ua rau nws lub neej tsis muaj zog, tab sis nws yuav cuam tshuam rau qhov loj qhov chaw. Qhov kev ua.
Thaum yuav kho vajtse, koj yuav tsum xub xav txog qhov teeb meem zoo. Txhob tsis quav ntsej qhov zoo vim tias koj nyiam cov style koj nyiam lossis tus nqi pheej yig. Nws zoo li kev kho vajtse qub, qhov txawv ntawm qhov txawv loj heev, qhov no yog qhov zoo tshaj plaws. Chav dej chav da dej ua rau me me, tab sis nws plays lub luag haujlwm tseem ceeb hauv chav dai kom zoo nkauj. Tom qab tag nrho, qhov chaw nyob hauv chav dej yog noo thiab ntub, ces peb yuav tsum yuav cov khoom zoo.
Muaj ntau yam khoom kho khoom siv thiab cov khoom sib txawv, tab sis cov khoom siv kho khoom ua si ua lub luag haujlwm nyob hauv tsev kho kom zoo nkauj. Xaiv cov khoom ntim zoo tuaj yeem ua tau ntau yam ntaub ntawv zoo nkauj thiab siv yooj yim dua. Tam sim no, muaj ntau tshaj kaum hom khoom kho khoom siv hauv cov khoom ua lag luam.
Cov khoom siv hluav taws xob tuaj yeem hu ua lub plawv ntawm cov qhov rooj thiab qhov rais, qhov rooj thiab qhov rais tag nrho ntawm txhua lub yeeb yam xws li cua txias tuaj, huab cua nruj, dej ceev nrooj, kev txuag hluav taws kub, hluav taws kub rwb thaiv tsev, lub rwb thaiv tsev, thiab lwm yam.
178. Cov qib theem ntawm cov txheej txheem ntawm cov khoom siv hauv kev txiav txim zoo li cas?
Peb paub hais tias precision machining yuav tsum tau high precision, precision machining nrog zoo rigidity, high manufacturing precision, thiab yog lub cuab tam qhov chaw, yog li nws muaj peev xwm ntawm qhov chaw nrog high precision.
Precision qhov ua yog tsis ua tiav tag nrho cov khoom txheem ntawm txhua qhov chaw hauv ib qho. Cov txheej txheem tseem ceeb ntawm kev ua tiav kev ua yuav muab faib ua cov theem hauv qab no:
1. Ntxhib theem. Tshaj tawm ntawm feem ntau ntawm cov nyiaj ua haujlwm rau txhua qhov chaw ua hauj lwm nto thiab tshuab siv zoo, feem ntau yog xav ua qhov tsim tau ntau li ntau tau.
2. Cov theem ua tiav. Cov teeb meem uas tshwm sim tom qab roughing, nyob rau hauv kev npaj rau qhov dej tiav, yuav tsum tau ib cov degree ntawm machining raug, xyuas kom zoo finishing nyiaj, thiab ua tiav theem nrab nto ua.
3. Cov theem tiav. Nyob rau theem no, kev txiav qhov loj, kev pub me me thiab qhov tob ntawm qhov kev txiav yog siv los txiav tawm ntawm qhov nyiaj xaus tshuav ntawm qhov txheej txheem dhau los, yog li ntawd cov nplaim ntawm ib sab tuaj yeem ua raws li kev cai ntawm tus qauv.
4. Qha theem. Nws yog tsuas yog siv los txo cov nqi npoo npaug los yog ntxiv dag zog rau kev ua haujlwm, thiab tsuas yog siv rau kev ua ntom zom saum npoo (r≤0.32 μm).
5. Ultra-precision machining theem. Tus zauv ua tiav yog 0.1-0.01 μm, thiab qhov nqi ntawm qhov chaw roughness yog ra≤0.001 μm. Txoj kev ua haujlwm tseem ceeb tshaj plaws yog: kev txiav ua tiav, nplaum iav sib tsoo, kev sib tsoo thiab kev sib tsoo.
Kev tsim cov txheej txheem rau kev txiav txim siab yog hais txog tag nrho cov txheej txheem ntawm cov khoom tsim los ntawm raw cov ntaub ntawv (los yog cov khoom tiav). Nws yog siv rau hauv kev ua cov khoom, nrog rau kev thauj mus los thiab cia cov khoom siv raw, kev npaj ntau lawm, kev ntxhib, ua ib feem thiab kev kho cua kub, khoom sib dhos thiab commissioning, pleev xim thiab ntim.
Dab tsi yog qhov tseem ceeb ntawm peb cov precision machining:
1. Yuav kom ntseeg tau tias qhov kev ua hauj lwm raug, roughing thiab xov yuav tsum tau nqa tawm nyias. Vim txoj kev ntxhib, ntau cov workpieces yuav raug txiav quab yuam, loj clamping quab yuam thiab qib siab kub, uas yog ib qho yooj yim ua rau tawv tawv. Muaj kev ntxhov siab loj hauv kev ua haujlwm. Yog tias qhov xov tiav thiab kev ntxhib yog tas li, qhov tseem ceeb tshaj tom qab ua tiav Txoj kev tshaj tawm yuav rov faib rau kev ntxhov siab thiab yuav sai sai no poob. Rau qee qhov chaw uas muaj cov cuab yeej ua haujlwm siab. Kev kub siab los yog kev laus yuav tsum tau ua tom qab roughing thiab ua ntej kev txiav txim kom tshem tawm kev ntxhov siab.
2. Kev tsim nyog ntawm cov cuab yeej ua khoom siv. Lub txheej txheem tseem ceeb ntawm kev ntxhib yog txiav tawm feem ntau ntawm kev txiav nyiaj thiab tsis tas yuav tsum tau ua dua ntawm kev txiav txim siab dua. Yog li, roughing cov cav tov tsuas xav tau high-power, low-precision machining. Xov kom tag nrho yuav tsum muaj tshuab ntau dua. Roughing thiab xov ntawm ntau yam cuab yeej tshuab tsis tsuas maximizes cov kev ua tau zoo ntawm cov khoom, tab sis kuj extends qhov kev pab cuam lub neej ntawm precision tshuab cuab yeej.
3. Feem ntau yuav tsum tau sov so thaum lub caij ua haujlwm. Txoj kev kho kom sov yog ua raws li nram qab no: txhawm rau txhim kho txoj kev ua tiav ntawm cov hlau, xws li kev nplawm, kev ua haujlwm, kev sib ntxub thiab kev kub ntxhov, thiab lwm yam., Nws yog feem ntau ua ntej ua haujlwm. Txhawm rau tshem tawm cov kev ntxhov siab, xws li kev laus tu thiab kev kho mob thiab kev kho mob, nws feem ntau yog tom qab roughing thiab ua ntej kawg. Txhawm rau txhawm rau txhim kho cov khoom sib txuas ntawm qhov chaw, kev sib tw, quenching, tempering, thiab lwm yam., Feem ntau yog ua tiav tom qab kho tshuab. Yog tias muaj deformation tom qab kev kho cua sov, qhov kawg yuav tsum tau npaj.
