Kev siv technology thiab cov yam ntxwv ntawm nyias-walled qhov chaw
Hauv kev ua cov khoom, qhov me me ntawm qhov ntim thiab qhov thinner lub thickness ntawm ib feem, qhov siab dua qhov kev ua haujlwm nyuaj, yog li cov txheej txheem ntawm cov phab ntsa nyias nyias yuav tsum tau ceev faj thiab ceev faj. Tom ntej no, Dongmo yuav coj koj cov txheej txheem thev naus laus zis thiab cov yam ntxwv ntawm cov phab ntsa nyias nyias. Kuv vam tias koj nyiam nws.
Thin-walled qhov chaw ua tshuab:
1. Lub workpiece tau muab faib ua cov txheej txheem ntxhib thiab zoo
Thaum zoo tig, vim qhov nyiaj txiav loj, lub zog clamping yog me ntsis loj dua, thiab qhov deformation yog loj dua; Thaum zoo tig, lub clamping quab yuam yuav me ntsis me me, ntawm ib sab, lub clamping deformation yog me me, thiab ntawm qhov tod tes, qhov zoo tig kuj tseem loj. Deformation tshwm sim los ntawm kev txiav quab yuam ntau dhau thaum lub sijhawm tig tuaj yeem raug tshem tawm.
2. Kev xaiv tsim nyog ntawm cov txheej txheem ntawm cov khoom siv
Thaum zoo-tig nyias-walled workpieces, lub rigidity ntawm lub cuab tam tuav yog siab, thiab wiper ntug ntawm lub tig lub cuab tam yog tsis yooj yim mus ntev heev, feem ntau 0.2-0.3mm, thiab qhov txiav ntug yuav tsum yog ntse.
3. Ua kom lub clamping contact nto
Siv lub tes tsho slotted lossis qee lub puab tsaig muag tshwj xeeb. Kev sib cuag saum npoo yog loj, yog li ntawd lub clamping quab yuam yog sib npaug ntawm cov khoom ua haujlwm, kom lub workpiece tsis yooj yim deformed thaum nws yog clamped.
4. Axial clamping fixture yuav tsum tau siv
Thaum tig nyias-walled workpieces, lub workpiece yog axially clamped los ntawm lub ntsej muag kawg ntawm lub tes tsho axial clamping (xov tes tsho). Vim hais tias lub clamping quab yuam yog faib raws axial kev taw qhia ntawm lub workpiece, thiab axial rigidity ntawm lub workpiece yog loj, nws tsis yog yooj yim los tsim clamping deformation.
5. Ua kom cov khoom siv tes ua rib
Qee qhov nyias-walled workpieces tshwj xeeb yog ua los ntawm ntau cov txheej txheem tav ntawm lawv qhov chaw clamping los txhim kho qhov nruj ntawm no, kom lub clamping quab yuam ua rau cov txheej txheem tav los txo qhov deformation ntawm lub workpiece. Tom qab ua tiav, cov txheej txheem tav tau raug tshem tawm.
6. Ua kom tiav cov kua txiav
Los ntawm tag nrho cov pouring tej kua, lub txiav kub yog txo thiab thermal deformation ntawm lub workpiece yog txo.
Nta ntawm nyias-walled qhov chaw technology
1. Vim yog cov phab ntsa nyias ntawm lub workpiece, nws yooj yim rau deform nyob rau hauv qhov kev txiav txim ntawm lub clamping quab yuam. Yog li cuam tshuam qhov tseeb qhov tseeb thiab qhov tseeb ntawm lub workpiece. Nyob rau hauv qhov kev txiav txim ntawm lub clamping quab yuam, nws yuav dhau los ua daim duab peb sab me ntsis, tab sis tom qab lub tsheb tswj tau, nws yuav tau txais lub qhov cylindrical. Thaum lub puab tsaig raug tso tawm thiab lub workpiece raug tshem tawm, vim lub elastic rov qab, lub voj voog sab nraud rov qab mus rau ib lub cylindrical zoo, thaum lub puab lub qhov ua ib daim duab peb sab. Yog hais tias ntsuas nrog ib lub micrometer sab hauv, lub diameters nyob rau hauv tag nrho cov lus qhia yog sib npaug, tab sis lub deformation tsis yog lub puab cylindrical nto, uas yog hu ua sib npaug txoj kab uas hla deformation.
2. Vim hais tias lub workpiece yog nyias, txiav cov cua sov yuav ua rau thermal deformation ntawm lub workpiece, ua rau nws nyuaj rau tswj qhov luaj li cas ntawm workpiece. Rau nyias-walled hlau workpieces nrog ib tug loj coefficient ntawm linear expansion, xws li tas mus li semi-tiav thiab tiav nyob rau hauv ib tug installation, lub thermal deformation ntawm lub workpiece tshwm sim los ntawm kev txiav cov cua sov yuav muaj kev cuam tshuam zoo rau nws qhov tseeb qhov tseeb, thiab qee zaum txawm tias. ua lub workpiece daig ntawm lub jig.
3. Nyob rau hauv qhov kev txiav txim ntawm txiav quab yuam, tshwj xeeb tshaj yog radial txiav quab yuam, kev co thiab deformation yog ib qho yooj yim rau tshwm sim, uas cuam tshuam rau lub dimensional raug, zoo, txoj hauj lwm raug thiab nto roughness ntawm lub workpiece.
