Flatness tsis yog khoom kim heev nyob rau hauv high-pressure hydraulic li qub los yog precision twj tso kua mis vaj tse - nws yog tsis-negotiable. Qhov sib txawv ntawm tsuas yog 0.02 hli thoob plaws 300-mm phaj-leveling nto tuaj yeem ua rau qhov tsis ua haujlwm ntxov ntxov, tsis sib xws ntawm kev thauj khoom, lossis kev puas tsuaj loj hauv kev sib koom ua ke ntawm cobalt-alloy piston twj tso kua mis. Peb tau pom nws ob zaug hauv 18 lub hlis dhau los: ib qho North American OEM ncua sij hawm xa khoom los ntawm rau lub lis piam tom qab tsis lees txais 47 lub tog raj kheej vaj tse - tsuas yog nrhiav cov hauv paus hauv paus tsis yog kev ua haujlwm yuam kev, tab sis tsis sib xws phaj-leveling upstream hauv raw casting prep.
Vim li cas "Plate Levelers Hlau Parts Factory" Yog Ib Lub Sijhawm Tshawb Nrhiav Tsis Txaus - thiab Cov Kws Ua Haujlwm Xav Tau
Cov pab pawg muag khoom feem ntau ntaus "phaj qib hlau qhov chaw tsim khoom" rau hauv Google xav tias yuav hloov pauv hloov pauv. Tab sis lub ntiaj teb tiag tiag flatness tswj pib ntev ua ntej leveling - nws pib nrog cov khoom xaiv, casting grain qauv, thiab thermal keeb kwm. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb kho phaj leveling tsis yog qhov kawg kov-up kauj ruam, tab sis raws li qhov kawg ntawm cov txheej txheem nruj nreem kaw: xuab zeb-cam khwb cia hlau foundations undergo stress-relief annealing * ua ntej * CNC lub ntsej muag-milling; AMS 5387 cobalt alloy blanks yog tuav ntawm 950 ° C rau 4 teev tom qab casting kom stabilize microstructure - ces cua txias nyob rau hauv kev tswj airflow kom txo warpage. Tsuas yog tom qab ntawd peb puas siv precision leveling ntawm dual-axis hydraulic platens nrog ± 0.5 µm repeatability.
Qhov no tsis yog cosmetic flattening. Nws yog functional stabilization. Peb lub cev lub siab lub cev xav tau ≤0.015 hli tag nrho cov ntsuas ntsuas (TIR) thoob plaws mating flanges. Winch center shaft rollers xav tau ≤0.025 mm runout tshaj 1.2 meters - ntsuas ntawm Zeiss Contura G2 RFS nrog ntsuas kub-paub qhov ntsuas. Peb txheeb xyuas txhua ntu nrog kev sib koom tes ntsuas tshuab (CMM), tsis yog ntawm kev tshuaj xyuas zaum kawg - tab sis kuj tom qab kev siv tshuab ntxhib, tom qab kev kho cua sov, thiab tom qab sib tsoo. Qhov kev pov thawj peb-taw qhia tau ua rau thermal distortion ntxov-ua ntej yuav raug nqi ntau dua.
Plaub Tsis-Tshaj Tawm rau Kev Tswj Xyuas Plate-Leveling
- Cov khoom siv traceability ua rau hauv kev ua haujlwm theem: Txhua T800 cobalt alloy billet nqa ib daim ntawv ntsuam xyuas zeb (MTR) nrog tag nrho chemistry thiab tensile cov ntaub ntawv. Peb hla MTR batch cov lej tiv thaiv kev sib tw - yog li yog tias flatness drift tshwm hauv Lot #QSY-2388, peb cais seb nws puas yog casting shrinkage, furnace cooling rate, los yog platen hnav.
- Txheej txheem-integrated metrology: Tsis yog "theem ces ntsuas." Peb theem thaum scanning-siv laser interferometry synchronized nrog hydraulic platen txav. Qhov no tshawb pom lub caij nplooj ntoo hlav hauv lub sijhawm tiag tiag, tshwj xeeb tshaj yog qhov tseem ceeb rau lub hauv paus ntawm cov twj tso kua mis uas muaj qhov seem uas muaj kev ntxhov siab nyob rau hauv feeb ntawm kev tshem tawm.
- Deg kev ruaj ntseg: Traditional leveling compresses subsurface layers, inducing micro-cracks nyob rau hauv hardened cobalt alloys. Peb txoj kev siv lub zog qis, siab zaus oscillation-25 Hz ntawm 0.3 hli amplitude-kom so cov kev ntxhov siab sab hauv yam tsis muaj cov yas deformation. Pom zoo los ntawm Barkhausen suab tsom xam ntawm txhua AMS 5387 nozzle batch.
- GD&T-paub qib kev ua kom zoo: Peb tsis flatten rau "zero" - peb theem rau cov ntaub ntawv ua haujlwm. Ib lub tog raj kheej vaj tse tsis yog theem rau nws lub ntsej muag loj; nws yog leveled rau cov kabmob bore axis, hais los ntawm tus tswv fixture. Qhov ntawd txhais tau hais tias kev sib tw quab yuam yog siv asymmetrically - xam rau ib feem geometry siv cov ntsiab lus finite simulation ua ntej khiav.
Dab tsi ua tsis tiav—Thiab yog vim li cas feem ntau lub Hoobkas tsis nco nws
Qee lub khw outsource leveling rau cov chaw pabcuam hlau dav dav. Lawv tau txais qhov "pas" - tab sis ua tsis tiav kev sim ua haujlwm. Vim li cas? Vim hais tias cov chaw no optimizes nto roughness, tsis haumxeeb flatness. Ib tus neeg siv khoom nyob sab Europe xa peb tsis lees txais lub hauv paus twj tso kua mis: nto TIR yog 0.012 hli, tab sis lawv xau ntawm 280 bar. Peb ntsuas flatness * txheeb ze rau mounting ntsia liaj qhov rooj lub voj voog *, tsis yog sab nrauv-thiab pom 0.041 hli sib txawv ntawm 8-bolt qauv. Qhov teeb meem tsis yog lub tshuab leveling. Nws yog lub ntsiab txhais.
Lwm tus tsuas yog tso siab rau CNC lub ntsej muag milling. Tab sis milling tshem tawm cov khoom - nws tsis txo kev ntxhov siab. Peb tau ntsuas txog 0.06 hli warpage nyob rau hauv 40-mm-thick steel castings * tom qab * milling, vim asymmetrical Tshuag tshem tawm. Peb qhov kev daws teeb meem? Pre-theem lub casting dawb paug, zeb nrog cov cuab yeej sib npaug, ces tom qab-theem nrog thermal so. Peb qhov kev cuam tshuam - tsis yog ib qho.
Los ntawm Flatness mus rau Functional Reliability
Qhov tseeb phaj-leveling kev vam meej qhia tau hais tias nyob rau hauv nqes hav: ntev lub neej nyob rau hauv hydraulic manifolds, zoo ib yam txaus tus nqi nyob rau hauv ntau theem twj, xoom vibration nyob rau hauv winch tsav shafts rotating ntawm 1,200 rpm. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY, peb tsis muag "paj daim hlau." Peb xa cov kev ruaj ntseg nyob rau hauv lub voj voog thermal, siab spikes, thiab cov neeg kho tshuab qaug zog - txheeb xyuas raws li ASTM E1157, ISO 1101, thiab cov neeg siv khoom tshwj xeeb ua haujlwm.
Yog tias koj daim ntawv thov xav kom flatness nyob rau hauv load - tsis yog ntawm lub rooj granite - pib nrog cov khoom siv, tsis yog tshuab specs. Demand traceability mus rau lub yaj batch. Yuav tsum tau GD&T-ua raws qib-tsis yog generic flattening. Thiab hais kom ntsuas ntawm txhua qhov thermal thiab mechanical hloov chaw. Qhov no yog li cas precision yuav kwv yees tau. Qhov ntawd yog li cas "phaj levelers hlau qhov chaw Hoobkas" nres ua ib lo lus tshawb nrhiav - thiab dhau los ua kev daws teeb meem engineering.
