Qhov nyob nram qab
In the aerospace and power industries, large-diameter thin-walled rings-such as engine housings, connector rings, and mounting flanges-are widely used for their lightweight structure and functional efficiency. Txawm li cas los xij, vim lawv cov kab ke geometric (cov kab uas hla loj vs. me me yog rhiab rau qhov kub} ua rau muaj kev cuam tshuam nrog lub sijhawm ua kom haum.
Tshwj xeeb tshaj yog thaum lub caij sab hauv kev ua haujlwm sab hauv, ua kom sov kub tuaj yeem ua raunonlinear thermal expansion, ua rau muaj kev hloov maj mam distortions uas kev cuam tshuam cov puag ncig thiab qhov tseeb ntawm qhov tseeb ntawm ntu kawg. Rau kev lag luam uas xav tau Micrometer -}}} Teb precision, qhov no yog qhov kev sib tw uas tsis tuaj yeem pom.
Qhov kev sib tw
Nyob rau hauv nyias -}}}} walled seem nrog qis tawv, txhua qhov nce hauv cov cuab yeej-workpient lub sij hawm tau tshwm sim hauv kev nce hauv zos kub. Txij li thaum muaj cua sov tsis tuaj yeem cuam tshuam tsis zoo thoob plaws cov khoom siv, tsis muaj cov cua sov gradients ua rautsis - Cov Khoom Siv Khoom Uas Muaj ZogCov. Qhov no yog qhov teeb meem tshwj xeeb hauv:
Siab - ceev tho txawv thiab contouringntawm incomet sab hauv
Cuam tshuam kev txiavqhov twg thermal spikes tshwm sim
XOV UA HAUJ LWM, qhov twg txawm tias tus mob me me rov qab ua rau ib feem tawm -- kam rau
Ib qho kev coj ua ntawm post - Machin Machine Txias Thiab Them Nyiaj Yog Tsis Txaus. Tiag - kev tswj lub sij hawm yog yuav tsum tau ua kom cov dynamic distortions.
BISHEN SOLDED: Ib tug ntse heev tswj hwm lub tswv yim
Kom tau raws li cov thermal stability xav tau ntawm nyias {{}}} walled nplhaib ntiv nplhaib machining, bishen tsim aNtau - Вase threase threadal tswj systemUa ke rau nws 5-axis gantry machining platforms:
Tiag - lub sijhawm soj ntsuam
Siab -}} scrarity infrared infors thiab embedded thermocouples txuas ntxiv mus txog ntawm thaj chaw yooj yim ntawm thaj chaw npau taws.
Segmented cua txias zoo
Hloov chaw ntawm tas li txias txias, lub kaw lus dynamically hloov kho txias siv los ntawm kev siv lub thawv {} - ua tiav, thiab xov. Qhov no txo thermal thermal poob siab thaum tswj cov khoom ruaj khov.
Laser Profiling rau contour tawm tswv yim
Ib qho tsis -} Hu tau laser scanner ua haujlwm txuas ntxiv profile tas mus li profile tshev thaum lub tshuab. Yog tias muaj kev sib txawv los ntawm kev sib tw lossis kev ncaj ncees tshwm sim vim yog cov khoom nthuav dav, cov cuab yeej siv tau hloov kho hauv lub sijhawm.
Post - tshuab tshuab ntxhua kub thiab kub
Tom qab ntxhib machining, feem yog tuav hauv kev tswj hwm ambient kub kom tso cai rau thermal so. Lub teeb ci hla dhau ua kom ua kom tiav kev ncaj ncees tas mus li.

Case Daim Ntawv Thov Cov Ntaub Ntawv Txuas: Lub nplhaib Txuas Txuas
Ib tug coj Aerospace Tier-1 tus neeg xa khoom ntsib tus nqi tsheb siab thaum tshuabTxhuas Alloy Cav Txuas RingsNrog ib phab ntsa tuab ntawm tsuas yog 4.2 hli thiab txoj kab uas hla ntawm 780 hli. Kev ruaj ntseg deformation tau mus txog li 0.05 hli vim txiav -} inducion thaum tshav kub.

BISHENS LUB CUAB YEEJ NPLECE lub tswv yim, ua ke nrog tiag- lub sij hawm contour ua kom sov thiab segmented txias, ua rau muaj peev xwm tsim cov khoom nyuaj nontseeg tau, pheej rov qab, thiab precisely.
