Cov teeb meem ntawm cov yeeb nkab hlau thiab lawv cov kev tiv thaiv

Cov txheej txheem ua tiav ntawm cov yeeb nkab hlau yog ib qho txheej txheem tseem ceeb thiab tseem ceeb kom tshem tawm cov qhov tsis zoo ntawm cov yeeb nkab hlau, txhim kho qhov zoo ntawm cov yeeb nkab hlau, thiab ua tau raws li qhov xav tau ntawm kev siv tshwj xeeb ntawm cov khoom. Cov yeeb nkab hlau ua tiav feem ntau suav nrog: kev ncaj cov yeeb nkab hlau, kev txiav kawg (chamfering, sizing), kev tshuaj xyuas thiab kev tshuaj xyuas (suav nrog kev tshuaj xyuas qhov zoo ntawm qhov chaw, kev tshuaj xyuas qhov ntev geometric, kev tshuaj xyuas tsis puas tsuaj thiab kev sim hydraulic, thiab lwm yam), kev sib tsoo, kev ntsuas qhov ntev, kev hnyav, kev pleev xim, kev luam ntawv thiab cov txheej txheem ntim khoom. Qee cov yeeb nkab hlau tshwj xeeb kuj xav tau kev tua phom saum npoo av, kev ua haujlwm kho tshuab, kev kho mob tiv thaiv xeb, thiab lwm yam.

(I) Cov teeb meem ntawm cov yeeb nkab hlau thiab lawv txoj kev tiv thaiv

⒈ Lub hom phiaj ntawm kev ncaj cov yeeb nkab hlau:
① Tshem tawm qhov khoov (tsis ncaj) uas tsim los ntawm cov yeeb nkab hlau thaum lub sijhawm dov, kev thauj mus los, kev kho cua sov thiab cov txheej txheem txias
② Txo qhov ovality ntawm cov kav hlau

⒉ Qhov tsis zoo ntawm cov yeeb nkab hlau thaum lub sijhawm ncaj: cuam tshuam nrog tus qauv tshuab ncaj, cov duab qhov, kev kho qhov thiab cov yam ntxwv ntawm cov yeeb nkab hlau.

⒊ Qhov tsis zoo ntawm cov yeeb nkab hlau ncaj: cov yeeb nkab hlau tsis ncaj (cov yeeb nkab kawg khoov), nkhaus, plaub fab, tawg, khawb ntawm qhov chaw thiab qhov nkag, thiab lwm yam.

(ii) Cov teeb meem ntawm kev sib tsoo thiab txiav cov yeeb nkab hlau thiab lawv txoj kev tiv thaiv

⒈ Lub hom phiaj ntawm kev sib tsoo qhov tsis zoo ntawm cov kav hlau: kom tshem tawm cov qhov tsis zoo ntawm cov kav hlau uas raug tso cai kom muaj los ntawm cov qauv kav hlau tab sis yuav tsum tau ntxuav hauv av kom txhim kho qhov zoo ntawm cov kav hlau.

2. Qhov tsis zoo los ntawm kev sib tsoo ntawm cov kav hlau: Qhov laj thawj tseem ceeb yog tias qhov tob thiab cov duab ntawm cov ntsiab lus sib tsoo tom qab sib tsoo tshaj qhov yuav tsum tau teev tseg hauv tus qauv, ua rau lub cheeb sab nraud thiab phab ntsa tuab ntawm cov kav hlau tshaj qhov sib txawv tsis zoo lossis muaj cov duab tsis xwm yeem.

⒊ Kev sib tsoo ntawm cov yeeb nkab hlau feem ntau yuav tsum ua tau raws li cov hauv qab no:
① Tom qab kho qhov tsis zoo ntawm cov yeeb nkab hlau, qhov tuab ntawm phab ntsa ntawm thaj chaw kho yuav tsum tsis pub tsawg dua qhov sib txawv ntawm qhov tuab ntawm phab ntsa ntawm cov yeeb nkab hlau, thiab qhov dav ntawm thaj chaw kho yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm qhov dav ntawm cov yeeb nkab hlau.
② Tom qab qhov chaw ntawm cov yeeb nkab hlau raug av, nws yog qhov tsim nyog los khaws qhov chaw hauv av ntawm cov yeeb nkab hlau ua ib qho chaw du thiab nkhaus (ntau dhau arc). Sib tsoo tob: dav: ntev = 1: 6: 8
③ Thaum sib tsoo cov yeeb nkab hlau tag nrho, yuav tsum tsis muaj qhov kub hnyiab lossis pom tseeb polygonal cim ntawm qhov chaw ntawm cov yeeb nkab hlau.
④Cov ntsiab lus sib tsoo ntawm cov yeeb nkab hlau yuav tsum tsis pub tshaj tus lej teev tseg hauv tus qauv.

⒋ Cov teeb meem tseem ceeb uas tshwm sim los ntawm kev txiav cov yeeb nkab hlau suav nrog: lub ntsej muag kawg ntawm cov yeeb nkab hlau tsis yog ntsug, muaj burrs thiab loops, thiab lub kaum sab xis tsis raug, thiab lwm yam.

⒌ Kev txhim kho qhov ncaj ntawm cov yeeb nkab hlau thiab txo qhov ovality ntawm cov yeeb nkab hlau yog qhov yuav tsum tau ua kom ntseeg tau tias qhov zoo ntawm cov yeeb nkab hlau txiav. Rau cov yeeb nkab hlau uas muaj cov ntsiab lus siab alloy, yuav tsum tsis txhob txiav nplaim taws ntau li ntau tau kom txo qhov tshwm sim ntawm cov yeeb nkab kawg tawg.

(iii) Cov teeb meem ntawm cov yeeb nkab hlau thiab kev tiv thaiv

⒈ Kev ua cov yeeb nkab hlau feem ntau suav nrog: kev sib tsoo ntawm qhov chaw, kev sib tsoo ntawm qhov chaw tag nrho thiab kev ua cov khoom siv kho tshuab.

⒉ Lub Hom Phiaj: Txhawm rau txhim kho qhov zoo ntawm qhov chaw thiab qhov tseeb ntawm cov kav hlau.

⒊ Cov cuab yeej siv rau kev sib tsoo tag nrho ntawm qhov chaw sab nraud ntawm cov yeeb nkab hlau feem ntau suav nrog: siv txoj siv sia, log sib tsoo thiab cov cuab yeej siv tshuab sib tsoo. Tom qab kev sib tsoo tag nrho ntawm qhov chaw ntawm cov yeeb nkab hlau, cov nplai oxide ntawm qhov chaw ntawm cov yeeb nkab hlau tuaj yeem raug tshem tawm tag nrho, qhov tiav ntawm cov yeeb nkab hlau tuaj yeem txhim kho, thiab qhov chaw ntawm cov yeeb nkab hlau kuj tuaj yeem raug tshem tawm. Qee qhov tsis zoo me me xws li cov kab nrib pleb me me, cov kab plaub hau, qhov, khawb, thiab lwm yam.
① Siv txoj siv sia los yog lub log sib tsoo kom sib tsoo tag nrho cov yeeb nkab hlau. Cov teeb meem tseem ceeb uas yuav tshwm sim muaj xws li: daim tawv nqaij dub ntawm cov yeeb nkab hlau, phab ntsa tuab dhau, cov chaw tiaj tus (polygons), qhov av, kub hnyiab thiab cov cim hnav, thiab lwm yam.
② Cov tawv dub ntawm qhov chaw ntawm cov yeeb nkab hlau yog tshwm sim los ntawm qhov sib tsoo me dhau lossis cov qhov ntawm qhov chaw ntawm cov yeeb nkab hlau. Kev nce qhov sib tsoo tuaj yeem tshem tawm cov tawv dub ntawm qhov chaw ntawm cov yeeb nkab hlau.
③ Lub phab ntsa tuab ntawm cov yeeb nkab hlau tsis kam rau siab vim tias qhov sib txawv tsis zoo ntawm phab ntsa tuab ntawm cov yeeb nkab hlau nws tus kheej loj dhau lossis qhov ntau ntawm kev sib tsoo loj dhau.
④ Kev kub hnyiab ntawm qhov chaw ntawm cov yeeb nkab hlau feem ntau yog tshwm sim los ntawm kev sib cuag ntau dhau ntawm lub log sib tsoo thiab qhov chaw ntawm cov yeeb nkab hlau, qhov sib tsoo ntawm cov yeeb nkab hlau hauv ib qho kev sib tsoo, thiab lub log sib tsoo siv yog ntxhib dhau.
⑤ Txo cov yeeb nkab hlau sib tsoo ib zaug. Siv lub log sib tsoo ntxhib rau kev sib tsoo cov yeeb nkab hlau thiab lub log sib tsoo me me rau kev sib tsoo me me. Qhov no tsis yog tsuas yog tiv thaiv kev kub hnyiab ntawm cov yeeb nkab hlau xwb, tab sis kuj txo cov cim hnav uas tsim los ntawm qhov chaw ntawm cov yeeb nkab hlau.

⒋ Siv tshuaj tua kab rau ntawm cov yeeb nkab hlau

① Cov yeeb nkab hlau nto txhaj tshuaj peening yog txau hlau txhaj tshuaj lossis quartz xuab zeb txhaj tshuaj ntawm qee qhov loj me rau ntawm qhov chaw ntawm cov yeeb nkab hlau ntawm qhov ceev ceev kom tsoo cov nplai oxide ntawm qhov chaw kom txhim kho qhov du ntawm cov yeeb nkab hlau nto.
② Qhov loj thiab qhov nyuaj ntawm cov xuab zeb txhaj tshuaj thiab qhov ceev ntawm kev txhaj tshuaj yog cov yam tseem ceeb uas cuam tshuam rau qhov zoo ntawm kev txhaj tshuaj rau ntawm qhov chaw ntawm cov yeeb nkab hlau.
⒌ Kev ua cov yeeb nkab hlau nto
①Qee cov kav hlau uas muaj qhov zoo dua sab hauv thiab sab nraud yuav tsum tau ua cov txheej txheem kho tshuab.
②Qhov tseeb ntawm qhov ntev, qhov zoo ntawm qhov chaw thiab qhov nkhaus ntawm cov kav dej ua haujlwm tsis muaj qhov sib piv los ntawm cov kav dej kub dov.
Hauv ntej, cov txheej txheem ua tiav yog ib qho txheej txheem tseem ceeb thiab tseem ceeb heev kom ntseeg tau tias cov kav hlau zoo. Kev ua kom lub luag haujlwm ntawm cov txheej txheem ua tiav zoo dua yuav pab txhim kho qhov zoo ntawm cov kav hlau.
