Vuam tsis yog tsuas yog cua sov thiab muab tub lim hlau - nws yog kev tswj hwm. Thaum lub sij hawm ib feem hloov 0.2 hli nyob rau hauv clamping siab, lub weld ob leeg poob kev sib raug zoo. Distortion nkag mus rau hauv. Hauv kev sib xyaw ua ke, cov khoom ntim qis-tshwj xeeb tshaj yog rau cov khoom sib dhos, cov khoom sib xyaw ua ke, lossis cov kab ke ua liaj ua teb-qhov no tsis yog qhov kev pheej hmoo. Peb tau pom nws ua ntej: ib tus neeg siv khoom hauv Wisconsin tau tshem tawm 17% ntawm qhov kev ua haujlwm thawj zaug vim tias lawv cov kev cai lub kaum sab xis-hlau jig tsis tuaj yeem tuav lub siab ntev hla rau lub qhov txuas ntawm lub tsheb laij teb txhuas. Lawv hloov mus rau ib 3D welding rooj. Cov khib nyiab poob rau 0.8%. Lub sijhawm voj voog poob los ntawm 41%.
Precision pib qhov twg lub hauv paus phaj raws li tus pin
Ib qhov tseeb 3D welding rooj tsis yog ib lub tiaj steel slab nrog drilled qhov. Nws yog ib qho kev sib koom ua haujlwm raws li kev ua haujlwm tsim nyob ib puag ncig peb axes ntawm kev rov ua dua: X ( kab kab rov tav), Y ( kab kab rov tav ), thiab Z ( ntsug qhov siab hloov ). Txhua qhov-feem ntau M6, M8, lossis 1/4′-20-tso rau ntawm daim phiaj meej (feem ntau 50 hli lossis 2-nti pitch) nrog rau qhov kam rau ua ≤ ± 0.05 hli. Pins xauv rau hauv cov qhov, ces txais modular accessories: lub kaum sab xis clamps, nres blocks, rotary positioners, los yog kev cai locators machined kom phim ib feem datums.
Qhov geometry-thawj txoj hauv kev no hloov kev kwv yees nrog kev teeb tsa traceable. Tsis muaj kev sau ntawv ntxiv, tsis muaj kev sim-thiab-yuam kev shimming ntxiv. Ib tus neeg siv khoom hauv lub teb chaws Yelemees txiav lub sijhawm tsim kho los ntawm 11 hnub mus rau 38 teev - tsis yog los ntawm kev siv CAD, tab sis los ntawm kev rov siv cov qauv digital ntawm lawv lub tsev qiv ntawv pin-thiab-clamp ncaj qha hauv SolidWorks. Lawv cov engineers tam sim no tsim cov teeb tsa virtual ua ntej cov khoom siv raw tuaj txog.
Qhov txiaj ntsig tiag tiag qhia tau thaum lub sijhawm rov ua dua. Thaum lub Tier-1 tus neeg muag khoom tsheb xav tau los ua pov thawj tsib lub cim sib txawv rau lub EV roj teeb tshiab, lawv siv ib lub rooj 3D nrog cov cuab yeej sib hloov tau. Tag nrho tsib lub tsev sib koom ua ke tib lub hauv paus kev tswj hwm. Dimensional deviations tau mapped - tsis tawm tsam nominal drawings - tab sis tawm tsam lub rooj tus kheej metrology siv. Cov ntaub ntawv ntawd tau pub ncaj qha rau hauv lawv DFM tshuaj xyuas lub voj.
Vim li cas feem ntau lub khw muag khoom ntawm "semi-modular"
Qee cov tuam txhab hu xov tooj rau txhua lub phaj nrog T-bolts "3D vuam rooj." Nws tsis yog. Muaj peev xwm 3D tiag tiag yuav tsum muaj peb yam tsis sib tham:
Rigid puag tsimYam tsawg kawg 40 hli tuab, kev ntxhov siab-relieved EN 10025 S355JR los yog ASTM A572 Qib 50 steel, nrog machined flatness ≤ 0.03 mm / m² Calibrated qhov qauv: CNC-bored, tsis drilled; Txhua lub qhov tau txheeb xyuas los ntawm CMM tawm tsam tus tswv cov ntsiab lus - tsis yog qhov nruab nrab ntawm qhov nruab nrab, tab sis perpendicularity rau lub dav hlau nto Z-axis repeatabilityQhov siab-adjustable pins nrog ntsuas phoo mechanisms uas tswj ± 0.02 hli ntsug txoj hauj lwm tom qab 5,000 cycles-tuaj tseeb raws li ISO 9283 Peb tau sim cov ntxhuav uas dhau qhov kev tshuaj ntsuam pom tab sis ua tsis tau zoo thermal cycling: tom qab 12 teev ntawm 60 ° C, tus pin qhov siab drifted 0.13 hli vim untempered cam khwb cia txhuas thav ntawv. Qhov drift ib leeg invalidated GD&T callouts rau perpendicularity ntawm welded flanges. Lub ntiaj teb durability tseem ceeb tshaj li daim ntawv qhia glossy.
Kev sib koom ua ke-tsis yog kev sib cais-yog qhov muaj txiaj ntsig sib xyaw
Ib tug standalone 3D vuam rooj muab precision. Tab sis thaum nws anchors ib tug tag nrho cov txheej txheem saw-stamping, dabtsi yog khoov, vuam, soj ntsuam-nws unlocks throughput profits tsis muaj ib lub tshuab yuav phim. Ntawm Botou Haijun Hlau Khoom Co., Ltd., peb khiav 3D rooj tsis raws li cov chaw ua haujlwm cais, tab sis raws li lub hauv paus paj hlwb ntawm peb cov hlwb sib xyaw.
Nov yog nws ua haujlwm li cas: Lub tsev sib sib zog nqus nqus hlau stainless tuaj txog ntawm peb cov xovxwm hydraulic. Nws cov ntaub ntawv tseem ceeb tau raug txheeb xyuas ntawm peb CMM - tom qab ntawd nws qhov chaw nyob ze rau lub ntsiab lus ntawm lub ntsiab lus raug kaw. Qhov kev sib koom ua ke tau ntws mus rau qhov chaw nres tsheb MIG robotic. Clamps koom nrog. Weld sequence executes. Tom qab-weld, tib lub CMM tshuaj xyuas qhov cuam tshuam tawm tsam thawj cov ntaub ntawv teeb tsa - tsis tiv thaiv kev kos duab, tab sis tawm tsam lub hom phiaj ntawm lub cev raug ntes ntawm t = 0.
Tsis txhais lus poob. Tsis muaj phau ntawv txhais lus. Tsuas yog rov ua tau, tshawb xyuas qhov geometry - hla stamping, sib sau, vuam, thiab QC. Tias yog vim li cas cov neeg siv khoom tsim hydraulic valve manifolds rau Middle Eastern oilfields qhia xoom teb tsis ua haujlwm dhau 36 lub hlis: txhua qhov sib koom ua ke tuav tib lub thermal profile, tib qhov sib txawv tswj, tib lub hauv paus nkag mus-vim tias feem tsis tau tso nws qhov chaw sib koom ua ke.
Pib nrog koj qhov txuas tsis muaj zog tshaj plaws - tsis yog koj cov peev nyiaj loj tshaj plaws
Koj tsis xav tau lub rooj 3m × 2m kom tau txais txiaj ntsig los ntawm 3D vuam. Pib me me: txheeb xyuas ib qho kev mob tshwm sim-xws li qhov tsis sib xws ntawm qhov kev sib haum xeeb ntawm cov nkhaus nkhaus, lossis warpage nyob rau hauv nyias-gauge sib dhos-thiab phim nws rau qhov tsawg tshaj plaws certified system uas daws nws. Ib lub rooj 1000 × 750 hli nrog M8 daim phiaj thiab 12-pin cov khoom siv ua haujlwm 83% ntawm cov khoom siv hauv nruab nrab peb pom txhua hnub.
Nug koj tus neeg muab khoom pov thawj - tsis yog thov. Thov CMM cov ntaub ntawv qhia txog qhov tseeb ntawm qhov chaw. Nug cov ntaub ntawv ntsuas ntawm tus pin tuav lub zog tom qab 10,000 cycles. Xyuas seb lawv cov phaj hauv paus siv cov hlau tsis zoo-tsis yog "hnyav" carbon xwb. Paub meej tias lawv cov clamps suav nrog cov ntsej muag tawv tawv, tsis yog stamped ntawv hlau xwb.
Vim hais tias precision fixturing tsis yog hais txog kev yuav khoom kho vajtse. Nws yog hais txog kev ntes engineering lub hom phiaj - thiab tuav nws, raws nraim, kom txog rau thaum kawg arc tawm mus. Qhov sib xyaw ua ke sib xyaw ua ke thoob plaws txhua qhov vuam, txhua qhov hloov pauv, txhua xyoo. Thiab qhov ntawd yog sai npaum li cas, muaj zog hlau fabrication pib - tsis yog ntawm lub teeb, tab sis ntawm lub rooj.
