Ib tug precision sheet hlau fabrication rooj tsis yog qhov chaw ua haujlwm nkaus xwb - nws yog lub hauv paus ntawm lub cev ntawm kev tswj qhov ntev, rov ua dua, thiab kev ntseeg siab ntawm tus neeg ua haujlwm. Peb tau saib engineers recalibrate tag nrho cov tsim tawm vim hais tias lawv cov ntxhuav warped nyob rau hauv thermal cycling. Peb tau pom cov neeg ua haujlwm khoov nres nres ib nrab-lub voj voog kom shim qhov sib txawv ntawm 0.15 hli - tsuas yog nrhiav tau lub hauv paus ua rau lub rooj flatness drifting tshaj ± 0.2 hli tshaj 1,200 mm. Hauv kev ua haujlwm siab ntawm daim ntawv hlau, lub rooj yog qhov chaw geometry pib.
Botou Haijun Hlau Khoom Co., Ltd. tsim cov khoom rau Tier-1 automotive lwm tus neeg uas tsis kam txais cov khoom nrog cumulative kam rau ua stack-up tshaj ± 0.12 hli. Yuav kom ua tau raws li qhov ntawd, txhua tus qauv qauv, txhua qhov sib sib zog nqus nqus sensor vaj tsev, txhua qhov sib dhos welded pib ntawm qhov chaw tsim kho kom ruaj ntseg-tsis yooj yim. Qhov ntawd txhais tau hais tias cam khwb cia-hlau puag daim hlau nrog 30+ xyoo ntawm kev ntxhov siab-relieved aging, tsis welded steel thav ntawv nquag mus rau micro-hloov tom qab rov clamping loads. Nws txhais tau hais tias hauv av granite lossis hardened steel phaj sab saum toj nrog flatness tau lees paub rau ISO 10791-7 Chav Kawm 4 (≤0.015 mm / m), txheeb xyuas siv laser interferometry-tsis yog tus lej ntsuas ib leeg. Qhov tseem ceeb tshaj plaws, nws txhais tau hais tias kev sib koom ua ke ntawm lub rooj rau hauv cov txheej txheem tag nrho: CNC xovxwm nres qhov chaw, CMM cov ntsiab lus pov thawj ua rau saum npoo, thiab T-slot qauv ua raws li lub tshuab kev sib koom ua ke - tsis ntxiv raws li kev xav tom qab.
Qee tus yuav sib cav tias $ 2,000 modular rooj daws teeb meem tib yam li $ 12,000 engineered platform. Tab sis hauv kev xa tawm tiag tiag, qhov kev xav ntawd ua tsis tiav ntawm peb lub ntsiab lus tseem ceeb. Ua ntej, thermal drift: hnav aluminium rooj nthuav dav 2.3 × sai dua hlau. 5 ° C ambient hloov thaum sawv ntxov teeb tuaj yeem ua rau 0.08 hli qhov yuam kev hla ntawm 1,000 mm layout - txaus rau misalign lub qhov qauv rau cov neeg hlau vuam fixtures. Thib ob, kev faib khoom thauj khoom: cov rooj sib txawv tsis tshua muaj qhov taw qhia dynamic deflection hauv qab 500 kg point loads. Peb tau ntsuas txog li 0.32 hli sag nyob rau hauv chav tsev nkag thaum lub sij hawm ib txhij multi-point clamping - ncaj qha hloov qhov yuam kev mus rau hauv lub kaum sab xis. Thib peb, kev sib raug zoo ntawm kev sib raug zoo: bolted-on tooling daim hlau feem ntau tsis muaj dowel-pin sau npe, cia kev sib tw nkag mus ntawm kev teeb tsa. Ntawm Haijun, tag nrho cov rooj tsim khoom siv lub tes tsho steel dowel nrog ≤0.005 hli bore-rau-pin clearance-thiab txhua daim phaj yog mapped ntawm CMM ua ntej tso.
Dab tsi cais qhov chaw ua haujlwm ntawm qhov tseeb sheet hlau fabrication rooj los mus rau plaub lub peev xwm tsis sib tham:
Flatness tuav nyob rau hauv thermal thiab mechanical loadKev ntsuas kub ntawm 25 ° C ± 1 ° C, tom qab 8 teev ntawm 60 ° C huab cua raug thiab 300 kg faib loading Integrated metrology reference system: Embedded M8 threaded qhov ntawm 100 mm daim phiaj, nrog rau qhov chaw raug traceable rau NIST cov qauv Clamping quab yuam tswj: T-slots ntsuas rau ≥12 kN clamping load ib 100 hli ntu, nrog xoom ntsuas twist nyob rau hauv tag nrho torque Material compatibility kev ruaj ntseg: Surfaces tiav rau Ra ≤0.4 µm rau stainless thiab txhuas tuav-tsis muaj micro-scratching thaum hloov ib feem Peb tsis muag cov rooj ua khoom muag. Peb embed lawv nyob rau hauv engineering workflows. Thaum cov neeg siv khoom siv tshuab ua liaj ua teb nyob sab Europe xav tau kev rov ua dua tshiab hla 14 kev ua haujlwm dabtsi yog khoov ntawm ib lub chassis bracket, peb tau tsim ib lub rooj nrog dual-zone qhov siab hloov kho-ib ntu xauv ntawm 920 hli rau kev sib sau, lwm qhov ntawm 850 hli rau kev thauj khoom neeg hlau - ob qho tib si sib koom ib lub dav hlau datum. Thaum lub North American automation integrator xav tau xoom rework ntawm laser-txiav mounting daim hlau, peb muab cov rooj nrog pre-machined siv npoo sib npaug rau lawv fiber ntau laser kerf dav (± 0.02 hli). Qhov no tsis yog customization. Nws yog qhov kev lav phib xaub tau muab txhais ua hlau thiab granite.
Saib tom ntej: Cov tiam tom ntej ntawm sheet hlau fabrication rooj systems yuav tsis cia li tuav qhov-lawv yuav ntsuas lawv. Haijun's R&D lab tam sim no tau lees paub cov ntsuas ntsuas ntsuas ntsuas thiab cov ntsuas hluav taws xob hloov pauv uas pub cov ntaub ntawv flatness tiag tiag rau lub sijhawm MES. Tsis yog ib qho tshiab, tab sis raws li kev kaw-voj tswj cov tswv yim: yog tias thermal expansion hloov Y-axis datum los ntawm 0.03 hli, CNC xovxwm nres them nyiaj tau los. Cov theem ntawm kev sib koom ua ke tsuas yog ua haujlwm thaum lub rooj tsis ua rooj tog thiab ua ib feem ntawm cov qauv zoo. Rau cov pab pawg tsim cov khoom siv qhov twg ± 0.05 hli txiav txim siab qhov tsis ua haujlwm - lossis qhov twg 95% ntawm lub sijhawm xa khoom hinges ntawm kev ua tiav thawj zaug - lub rooj tsis yog qhov pib. Nws yog qhov ntsiag to guarantee.
