Raws li cov kev xav tau ntawm kev tsim khoom tsim, lub Hoobkas npaj yuav tsim kom muaj ibpob valvesphere processing ntau lawm kab. Txij li thaum lub Hoobkas tam sim no tsis muaj tiav stainless hlau sphere casting thiab forging khoom (lub nroog cheeb tsam tsis tso cai rau cov khoom siv uas cuam tshuam rau lub nroog ib puag ncig), sphere blanks cia siab rau outsourcing processing, tsis tsuas yog tus nqi siab, qhov zoo yog tsis ruaj khov. , tab sis lub sij hawm xa tuaj tsis tuaj yeem lav, uas cuam tshuam rau kev tsim khoom ib txwm muaj. Tsis tas li ntawd, cov blanks tau txais los ntawm ob txoj kev no muaj cov nyiaj ua haujlwm loj thiab siv cov khoom siv tsawg. Tshwj xeeb, cov cam khwb cia spheres muaj qhov tsis zoo xws li capillary cua to, uas ua rau cov khoom lag luam siab thiab kev ruaj ntseg nyuaj, uas cuam tshuam rau kev tsim khoom thiab kev loj hlob ntawm peb lub Hoobkas. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau hloov kho txoj kev ua haujlwm thev naus laus zis. Tus editor ntawm Xianji.com yuav qhia luv luv rau koj txog nws txoj kev ua haujlwm.
1. Lub hauv paus ntsiab lus ntawm sphere spinning
1.1 Technical parameters of valve spheres (saib Table

1.2. Kev sib piv ntawm sphere forming method
(1) Casting method
Qhov no yog ib txoj kev ua ib txwm ua. Nws yuav tsum tau ua kom tiav cov khoom siv rau smelting thiab pouring. Nws kuj xav tau ib tsob nroj loj thiab ntau tus neeg ua haujlwm. Nws yuav tsum muaj kev nqis peev loj, ntau cov txheej txheem, cov txheej txheem ntau lawm, thiab ua rau muaj kuab paug ib puag ncig. Txhua txheej txheem Cov qib kev txawj ntawm cov neeg ua haujlwm ncaj qha cuam tshuam rau qhov zoo ntawm cov khoom. Qhov teeb meem ntawm sphere pore leakage tsis tuaj yeem daws tau tag nrho, thiab cov nyiaj siv ua haujlwm ntxhib yog loj, thiab cov khib nyiab loj. Nws feem ntau pom tias qhov tsis xws luag casting ua rau nws scrapped thaum lub sij hawm ua, uas yuav ua rau kom tus nqi ntawm cov khoom. , Zoo tsis tuaj yeem lav, txoj kev no yuav tsum tsis txhob raug coj los ntawm peb lub Hoobkas.
(2) Forging method
Qhov no yog lwm txoj kev siv los ntawm ntau lub tuam txhab valve hauv tsev tam sim no. Nws muaj ob txoj hauv kev ua haujlwm: ib qho yog siv cov hlau puag ncig los txiav thiab cua sov forge rau hauv cov khoom kheej kheej kheej kheej, thiab tom qab ntawd ua cov khoom siv tshuab. Qhov thib ob yog molding stainless hlau phaj txiav mus rau hauv ib puag ncig zoo ntawm ib tug loj xovxwm kom tau ib tug hollow hemispherical dawb paug, uas yog ces welded mus rau hauv ib tug spherical dawb paug rau txhua yam kev ua. Txoj kev no muaj kev siv cov khoom siv ntau dua, tab sis lub zog muaj zog Cov xovxwm, cua sov rauv, thiab argon vuam cov cuab yeej kwv yees xav tau kev nqis peev ntawm 3 lab yuan los tsim cov khoom tsim tau. Txoj kev no tsis haum rau peb lub Hoobkas.
(3) Txoj kev spinning
Cov txheej txheem hlau spinning yog ib txoj kev ua tiav nrog tsawg dua thiab tsis muaj chips. Nws belongs rau ib ceg tshiab ntawm kev ua haujlwm siab. Nws muab cov yam ntxwv thev naus laus zis ntawm forging, extrusion, dov thiab dov, thiab muaj kev siv cov khoom siv siab (txog 80-90%). ), txuag ntau lub sijhawm ua haujlwm (1-5 feeb ua), cov khoom siv zog tuaj yeem ua ob npaug tom qab spinning. Vim lub cheeb tsam me me ntawm lub log tig thiab lub workpiece thaum lub sij hawm spinning, cov khoom siv hlau yog nyob rau hauv ob txoj kev los yog peb-txoj kev compressive stressive xeev, uas yog ib qho yooj yim rau deform. Raws li lub zog me me, chav tsev siab dua hu rau kev ntxhov siab (txog 25- 35Mpa), yog li, cov khoom siv yog qhov hnyav thiab tag nrho lub zog xav tau me me (tsawg dua 1/5 txog 1/4 ntawm cov xovxwm). Tam sim no nws tau lees paub los ntawm kev lag luam valve txawv teb chaws raws li kev siv hluav taws xob txuag hluav taws xob kheej kheej, thiab nws kuj tseem siv tau rau kev ua lwm yam hollow rotating qhov chaw.
Spinning tshuab tau siv dav thiab tsim los ntawm kev kub ceev txawv teb chaws. Cov cuab yeej siv tshuab thiab cov cuab yeej siv tau zoo heev thiab ruaj khov, thiab tsis siv neeg tswj kev sib koom ua ke ntawm cov tshuab, hluav taws xob thiab hydraulic yog pom tau. Tam sim no, spinning thev naus laus zis kuj tau tsim kho zoo heev hauv kuv lub teb chaws, thiab tau nkag mus rau theem ntawm kev nyiam thiab kev ua tau zoo.
2. Technical tej yam kev mob ntawm spinning sphere dawb paug
Raws li cov kev xav tau ntawm peb lub Hoobkas thiab ua ke nrog cov yam ntxwv ntawm spinning deformation, cov txheej txheem hauv qab no tau kos:
(1) Spinning khoom thiab hom: 1Gr18Nr9Tr, 2Gr13 steel yeeb nkab lossis steel phaj;
(2) Cov duab thiab cov qauv ntawm spinning kheej kheej (saib daim duab 1):

3. Spinning tswvyim
Cov nyhuv ntawm qhov sib txawv ntawm qhov sib txawv vim qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv. Tom qab kev txheeb xyuas, muaj ob txoj kev daws teeb meem:
3.1. Steel yeeb nkab necking spinning txoj kev
Cov tswv yim no tau muab faib ua peb kauj ruam: thawj kauj ruam yog txiav cov yeeb nkab steel raws li qhov loj me thiab clamp nws nyob rau hauv lub spindle chuck ntawm spinning tshuab cuab yeej tig nrog spindle. Nws txoj kab uas hla yog maj mam txo thiab kaw (saib daim duab 2) los tsim ib lub voj voog ib nrab; Qhov thib ob kauj ruam yog txiav tawm qhov tsim sphere thiab txheej txheem vuam zawj; Qhov thib peb kauj ruam yog welding ob hemispheres nrog argon welding ib leeg. Qhov yuav tsum tau hollow sphere dawb paug.

Qhov zoo ntawm cov yeeb nkab steel necking spinning txoj kev: tsis muaj pwm yuav tsum tau, thiab cov txheej txheem tsim yog kuj yooj yim; qhov tsis zoo yog: yuav tsum muaj cov yeeb nkab steel tshwj xeeb, muaj welds, thiab tus nqi ntawm cov yeeb nkab steel yog siab dua.
