Txoj kev ua tiav ntawm cov kav hlau steel yog ib qho tseem ceeb thiab cov txheej txheem tseem ceeb los tshem tawm qhov tsis xws luag hauv cov kav hlau, txhim kho cov kav dej steel zoo, thiab ua tau raws li cov kev xav tau ntawm kev siv tshwj xeeb ntawm cov khoom.Steel yeeb nkab xov feem ntau suav nrog: steel yeeb nkab ncaj, txiav kawg ( chamfering, sizing), tshuaj xyuas thiab tshuaj xyuas (nrog rau kev soj ntsuam zoo ntawm qhov chaw, geometric dimension soj ntsuam, tsis muaj kev puas tsuaj thiab kuaj hydraulic, thiab lwm yam), sib tsoo, ntsuas qhov ntev, qhov hnyav, pleev xim, luam ntawv thiab ntim cov txheej txheem. Qee qhov tshwj xeeb-lub hom phiaj steel kav kuj xav tau qhov chaw txhaj tshuaj blasting, mechanical processing, anti-corrosion treatment, thiab lwm yam.
(I) Cov yeeb nkab steel ncaj nraim thiab lawv cov kev tiv thaiv
⒈ Lub hom phiaj ntawm steel yeeb nkab straightening:
① Tshem tawm qhov dabtsi yog khoov (tsis ncaj) uas ua los ntawm cov yeeb nkab steel thaum lub sij hawm dov, kev thauj mus los, kev kho cua sov thiab cov txheej txheem txias
② Txo cov ovality ntawm cov kav hlau
⒉ Cov kev tsis zoo uas tshwm sim los ntawm cov yeeb nkab steel thaum lub sij hawm txoj kev ncaj: ntsig txog cov qauv ntawm lub tshuab ncaj, lub qhov zoo, qhov kev hloov kho thiab cov yam ntxwv ntawm cov yeeb nkab steel.
⒊ Cov kev tsis zoo hauv cov yeeb nkab steel ncaj: cov kav hlau tsis ncaj (cov yeeb nkab kawg khoov), dented, squared, tawg, nto khawb thiab indentations, thiab lwm yam.
(ii) Cov yeeb nkab steel sib tsoo thiab txiav qhov tsis xws luag thiab tiv thaiv lawv
⒈ Lub hom phiaj ntawm kev sib tsoo deg deg ntawm cov kav hlau: txhawm rau tshem tawm qhov tsis xws luag uas tau tso cai los ntawm cov qauv steel yeeb nkab tab sis yuav tsum tau ua kom huv si hauv av txhawm rau txhim kho qhov zoo ntawm cov kav hlau.
2. Kev puas tsuaj tshwm sim los ntawm kev sib tsoo ntawm cov yeeb nkab steel: Qhov laj thawj tseem ceeb yog qhov tob thiab cov duab ntawm cov ntsiab lus sib tsoo tom qab sib tsoo ntau tshaj qhov yuav tsum tau teev nyob rau hauv tus qauv, ua rau sab nraud txoj kab uas hla thiab phab ntsa thickness ntawm cov yeeb nkab steel kom dhau qhov tsis zoo sib txawv. los yog muaj lub cev tsis zoo.
⒊ Steel yeeb nkab nto sib tsoo yuav tsum feem ntau ua tau raws li cov hauv qab no:
① Tom qab kho qhov tsis xws luag ntawm cov yeeb nkab steel, cov phab ntsa tuab ntawm qhov chaw kho tsis tuaj yeem tsawg dua qhov tsis zoo ntawm cov phab ntsa nominal thickness ntawm cov yeeb nkab steel, thiab sab nraud ntawm qhov chaw kho yuav tsum ua raws li qhov yuav tsum tau ua. sab nraud txoj kab uas hla ntawm cov yeeb nkab steel.
②Tom qab lub npoo ntawm cov yeeb nkab steel yog hauv av, nws yog ib qho tsim nyog yuav tsum khaws cov av ntawm cov yeeb nkab steel raws li ib qho nkhaus nkhaus (ntau arc). Sib tsoo qhov tob: dav: ntev = 1:6:8
③ Thaum sib tsoo cov yeeb nkab steel tag nrho, yuav tsum tsis txhob muaj overburning lossis pom tseeb polygonal cov cim ntawm qhov chaw ntawm cov yeeb nkab steel.
④ Cov ntsiab lus sib tsoo nto ntawm cov yeeb nkab steel yuav tsum tsis pub tshaj tus lej teev hauv tus qauv.
⒋ Cov teeb meem tseem ceeb tshwm sim los ntawm kev txiav cov yeeb nkab steel muaj xws li: lub ntsej muag kawg ntawm cov yeeb nkab steel tsis yog ntsug, muaj burrs thiab loops, thiab lub kaum sab xis yog tsis raug, thiab lwm yam.
⒌ Txhim kho qhov ncaj ntawm cov yeeb nkab steel thiab txo qhov ovality ntawm cov yeeb nkab steel yog qhov yuav tsum tau ua ua ntej kom ntseeg tau qhov kev txiav zoo ntawm cov yeeb nkab steel. Rau cov kav hlau uas muaj cov ntsiab lus siab alloy, nplaim taws yuav tsum zam kom ntau li ntau tau kom txo tau qhov tshwm sim ntawm cov yeeb nkab kawg tawg.
(iii) Cov yeeb nkab steel nto ua qhov tsis xws luag thiab tiv thaiv lawv
⒈ Steel yeeb nkab nto ua haujlwm feem ntau suav nrog: nto txhaj tshuaj peening, zuag qhia tag nrho nto sib tsoo thiab txhua yam ua.
⒉ Lub Hom Phiaj: Txhawm rau txhim kho qhov zoo ntawm qhov chaw thiab qhov tseeb ntawm cov kav dej steel.
⒊ Cov cuab yeej rau kev sib tsoo tag nrho ntawm cov kav hlau sab nrauv feem ntau suav nrog: cov hlua khi, sib tsoo lub log thiab cov cuab yeej siv tshuab sib tsoo. Tom qab tag nrho kev sib tsoo ntawm cov yeeb nkab steel nto, cov oxide nplai ntawm cov yeeb nkab steel tuaj yeem raug tshem tawm tag nrho, qhov ua tiav ntawm cov yeeb nkab steel tuaj yeem txhim kho, thiab cov yeeb nkab steel tuaj yeem raug tshem tawm. Qee qhov me me xws li cov kab nrib pleb me me, cov kab plaub hau, qhov pits, khawb, thiab lwm yam.
① Siv ib txoj siv abrasive los yog lub log sib tsoo kom tag nrho cov yeeb nkab steel. Cov kev tsis zoo tseem ceeb uas yuav ua rau muaj xws li: cov tawv nqaij dub ntawm cov yeeb nkab steel, cov phab ntsa tuab heev, qhov chaw tiaj tus (polygons), qhov pits, hlawv thiab hnav cov cim, thiab lwm yam.
② Cov tawv nqaij dub nyob rau saum npoo ntawm cov yeeb nkab steel yog tshwm sim los ntawm kev sib tsoo me me los yog cov pits ntawm cov yeeb nkab steel. Kev sib tsoo ntau ntxiv tuaj yeem tshem tawm cov tawv nqaij dub ntawm cov yeeb nkab steel nto.
③ Lub steel yeeb nkab phab ntsa thickness yog tsis kam rau siab vim qhov tsis zoo sib txawv ntawm cov phab ntsa thickness ntawm cov yeeb nkab steel nws tus kheej yog loj heev los yog cov nyiaj sib tsoo loj heev.
④ Kev kub nyhiab ntawm cov yeeb nkab steel feem ntau yog tshwm sim los ntawm kev sib cuag ntau dhau ntawm kev sib tsoo lub log thiab qhov chaw ntawm cov yeeb nkab steel, qhov sib tsoo ntawm cov yeeb nkab steel nyob rau hauv ib qho kev sib tsoo, thiab kev sib tsoo lub log siv yog ntxhib heev.
⑤ Txo cov hlau yeeb nkab sib tsoo ntawm ib zaug. Siv lub pob zeb sib tsoo rau kev sib tsoo ntawm cov yeeb nkab steel thiab lub log sib tsoo zoo rau kev sib tsoo zoo. Qhov no tuaj yeem tsis tsuas yog tiv thaiv kev kub nyhiab ntawm cov yeeb nkab steel, tab sis kuj txo qis cov cim coj ua rau ntawm cov yeeb nkab steel.
⒋ Tua peening ntawm steel yeeb nkab nto
① Steel yeeb nkab nto txhaj tshuaj peening yog tshuaj tsuag hlau txhaj tshuaj los yog quartz xuab zeb txhaj tshuaj ntawm ib tug tej yam me me rau ntawm qhov chaw ntawm cov yeeb nkab steel ntawm ib tug ceev ceev mus khob tawm cov oxide teev nyob rau saum npoo los txhim kho cov smoothness ntawm cov yeeb nkab steel nto.
② Qhov loj thiab tawv ntawm cov xuab zeb txhaj tshuaj thiab txhaj tshuaj nrawm yog qhov tseem ceeb cuam tshuam rau qhov zoo ntawm kev txhaj tshuaj peening ntawm cov yeeb nkab steel.
⒌ Steel yeeb nkab nto machining
① Qee cov kav hlau uas muaj qhov siab dua sab hauv thiab sab nrauv zoo yuav tsum tau ua cov tshuab ua haujlwm.
② Qhov tseeb qhov tseeb, qhov zoo ntawm qhov chaw thiab qhov curvature ntawm cov kav dej tsis sib haum los ntawm cov kav dej kub dov.
Nyob rau hauv luv luv, cov txheej txheem tiav yog ib qho tseem ceeb thiab tseem ceeb heev txheej txheem los xyuas kom meej qhov zoo ntawm steel kav. Kev txhim kho lub luag haujlwm ntawm cov txheej txheem tiav yuav tsis xav tau kev pab ntxiv txhawm rau txhim kho qhov zoo ntawm cov kav dej steel.
