Cov khoom yog descaled. Nyob rau ntawm qhov chaw machined ntawm qhov chaw, yuav tsum tsis txhob muaj qhov tsis xws luag xws li khawb, abrasions, thiab lwm yam uas ua rau qhov chaw ntawm qhov chaw puas. Lub unmarked zoo kam rau ua yuav tsum tau raws li qhov yuav tsum tau ntawm GB {{0}}, thiab lub unmarked ntev dimension tso cai sib txawv yog ± 0.5 hli. Casting kam rau ua ib cheeb tsam yog symmetrical rau qhov yooj yim dimensional configuration ntawm cov dawb paug casting. Kev sib dhos ntawm dov bearings raug tso cai siv roj cua sov rau kev them nyiaj kub, thiab qhov kub ntawm cov roj yuav tsum tsis pub tshaj 100 degree. Sealing packing lossis sealant tau tso cai thaum sib sau ua ke cov tshuab hydraulic, tab sis yuav tsum tau tiv thaiv kom tsis txhob nkag mus rau hauv qhov system. Cov khoom thiab cov khoom uas nkag mus rau hauv lub rooj sib txoos yuav tsum muaj daim ntawv pov thawj ntawm lub chaw soj ntsuam ua ntej lawv tuaj yeem sib sau ua ke. Cov khoom yuav tsum tau ntxuav thiab ntxuav ua ntej sib dhos, tsis muaj burrs, flash, oxide nplai, xeb, chips, roj, xim thiab hmoov av.
Ua ntej sib dhos, lub ntsiab haum qhov ntev ntawm cov khoom thiab cov khoom, tshwj xeeb tshaj yog qhov cuam tshuam haum qhov ntev thiab qhov tseeb, yuav tsum tau tshuaj xyuas. Thaum lub sij hawm sib dhos txheej txheem, cov khoom tsis raug tso cai rau khob, tsoo, khawb thiab xeb. Thaum zawm screws, bolts thiab txiv ntseej, nws yog nruj me ntsis txwv tsis pub tawm tsam los yog siv cov ntsia hlau tsis zoo thiab cov wrenches. Tom qab zawm, cov ntsia hlau ntsia hlau, cov txiv ntseej thiab cov ntsia hlau, thiab lub taub hau ntawm lub bolts yuav tsum tsis txhob puas. Cov fasteners uas tau teev nruj torque yuav tsum tau nruj nrog ib tug torque ciaj ntswj thiab nruj raws li qhov teev nruj torque. Cov nplaum ntau dhau uas ntws tawm yuav tsum tau muab tshem tawm tom qab kev sib txuas. Lub nplhaib sab nraud ntawm cov kabmob thiab lub qhov ib nrab ntawm lub rooj zaum qhib thiab cov kabmob npog tsis raug tso cai rau daig; lub nplhaib sab nraud ntawm cov kabmob thiab lub qhov ib nrab ntawm lub rooj zaum qhib thiab cov kabmob npog yuav tsum muaj kev sib cuag zoo. Nws yuav tsum nyob rau hauv ib qho kev sib cuag nrog lub hau bearing nyob rau hauv ib tug ntau yam ntawm 90 degree symmetrical rau cov kab nruab nrab ntawm 120 degree ntawm cov kab nruab nrab. Thaum kuaj nrog lub ntsuas ntsuas qhov ntsuas siab hauv qhov saum toj no, 0.03mm lub ntsuas ntsuas ntsuas yuav tsum tsis txhob muab tso rau hauv 1/3 ntawm qhov dav ntawm lub nplhaib sab nraud.
Tom qab lub nplhaib sab nraud tau sib sau ua ke, nws yuav tsum nyob rau hauv kev sib cuag nrog lub ntsej muag kawg ntawm cov kabmob cap ntawm qhov chaw kawg. Tom qab lub dov bearing yog ntsia, nws yuav tsum yoog raws thiab ruaj khov rau tig los ntawm tes. Qhov sib koom ua ke ntawm cov kabmob sab sauv thiab sab qis yuav tsum tau txuas nrog thiab tsis tuaj yeem kuaj xyuas nrog lub ntsuas {{0}}.05mm feeler gauge. Thaum kho cov kabmob bush nrog tus pin nrhiav tus pin, laum lub pob khawm thiab faib tus pin nyob rau hauv cov xwm txheej uas lub qhov ncauj lub ntsej muag thiab lub ntsej muag kawg ntawm cov hav txwv yeem yog flush nrog lub qhov qhib thiab kaw lub ntsej muag thiab lub ntsej muag kawg ntawm qhov cuam tshuam cov kabmob. Cov pins yuav tsum tsis txhob xoob tom qab tau tsav mus rau hauv. Thaum lub npoo ntawm cov kabmob cov kabmob yog xim daj, nws tsis raug tso cai siv, thiab tsis pub muaj nucleation nyob rau hauv qhov kev sib cuag lub kaum sab xis. Qhov chaw nucleation sab nraud ntawm lub kaum sab xis yuav tsum tsis pub ntau tshaj 10 feem pua ntawm tag nrho cov cheeb tsam ntawm qhov chaw tsis sib cuag. Lub ntsej muag kawg ntawm lub iav (worm iav) thiab lub xub pwg nyom (los yog lub ntsej muag kawg ntawm lub tes tsho) yuav tsum haum ua ke, thiab 0.05mm feeler gauge yuav tsum tau siv rau kev tshuaj xyuas. Thiab cov kev cai verticality ntawm iav siv kawg lub ntsej muag thiab lub axis yuav tsum tau lav.
nruj me ntsis xyuas thiab tshem tawm cov ces kaum ntse, burrs thiab cov khoom txawv teb chaws sab laug nyob rau hauv kev ua cov khoom ua ntej sib dhos. Xyuas kom tseeb tias cov ntsaws ruaj ruaj tsis khawb thaum lawv raug ntsia. Qhov chaw casting tsis tso cai rau qhov chaw txias, tawg, shrinkage kab noj hniav thiab nkag mus rau qhov tsis xws luag thiab tsis tiav loj. Cov castings yuav tsum tau muab ntxuav kom tsis muaj burrs thiab flashes, thiab lub ncuav risers ntawm qhov tsis ua tiav yuav tsum tau muab ntxuav thiab yaug nrog rau saum npoo ntawm cov castings. Cov cim cam khwb cia thiab cov cim rau ntawm qhov chaw uas tsis yog tshuab ntawm cov castings yuav tsum tau txheeb xyuas kom meej, thiab cov haujlwm thiab cov fonts yuav tsum ua tau raws li qhov xav tau ntawm cov duab kos. Castings yuav tsum tau ntshiab ntawm pouring risers, ya spurs, thiab lwm yam. Cov seem seem ntawm lub pouring riser nyob rau hauv uas tsis yog-machined nto yuav tsum tau leveled thiab polished kom tau raws li qhov yuav tsum tau zoo nto. Cov xuab zeb moulding, core sand thiab core pob txha ntawm lub casting yuav tsum tau muab ntxuav. Lub casting muaj inclined qhov chaw, thiab nws qhov ntev kam rau ua cheeb tsam yuav tsum tau symmetrically teem raws lub inclined dav hlau.
Hom txoj cai thiab tsis ncaj ncees lawm thiab kev sib txawv ntawm tus thawj coj yuav tsum raug kho kom ua tiav qhov kev hloov pauv thiab ua kom pom qhov zoo. Qhov chaw tsis siv tshuab ntawm cov khoom siv tshuab castings yuav tsum tau txhaj tshuaj peened lossis cov menyuam kho kom ua tau raws li qhov xav tau ntawm kev huv huv Sa2 1/2 qib.
Qhov saum npoo ntawm casting yuav tsum tiaj tus, thiab lub rooj vag, burr, nplaum xuab zeb, thiab lwm yam yuav tsum tau ntxuav. Castings tsis raug tso cai kom muaj qhov tsis xws luag xws li cov khoom txias, cov kab nrib pleb, qhov, thiab lwm yam uas cuam tshuam rau kev siv. Txhua qhov chaw hlau uas yuav tsum tau pleev xim yuav tsum tau muab tshem tawm los ntawm xeb, nplai, roj, hmoov av, av nkos, ntsev thiab av ua ntej pleev xim.
