Thaum cov kws tshaj lij qhia Alloy 400 rau qhov tseem ceeb hydraulic valve vaj tsev lossis cov khoom siv piston twj tso kua mis siab, lawv tsis yog xaiv cov khoom siv xwb - lawv tau cog lus rau qhov ruaj khov, kev tiv thaiv corrosion nyob rau hauv ib puag ncig chloride-nplua nuj, thiab kwv yees machinability nyob rau hauv nruj GD&T tolerances. Qhov kev cog lus ntawd tsuas yog tuav yog tias tus alloy 400 feem Hoobkas xa cov khoom pov thawj tau ua pov thawj kev paub nrog cov hlau alloy qhov quirks: nws txoj haujlwm-hardening nyiam, thermal conductivity txwv, thiab rhiab heev rau residual kev ntxhov siab thaum kho cua sov.
Peb tau pom ntau qhov chaw nres tsheb - tsis yog los ntawm kev tsim teeb meem, tab sis los ntawm kev tsim khoom tsis sib xws. Ib tus neeg siv khoom ib zaug xa peb daim duab rau lub Alloy 400 siab nyem lub cev nrog ± 0.01 hli qhov tseeb txoj hauj lwm ntawm yim M12 threaded ports. Cov neeg muag khoom yav dhau los tau siv cov txheej txheem txheej txheem thiab cov dej txias txias. Qhov tshwm sim? Peb ntu ntu, micro-cracks ze ntawm cov hauv paus hniav, thiab ncua ob lub lis piam. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tshuab tib yam uas siv qis-RPM, siab-torque spindle tswv yim, cua daj cua dub es tsis txhob dej nyab, thiab ua ntu zus roughing-tiav dhau ntawm tib lub teeb-ua kom thermal distortion hauv qab 0.005 hli. Qhov ntawd tsis yog txoj kev xav. Nov yog kev xyaum ua txhua hnub.
Precision tsis ntxiv-Nws tau ua rau hauv cov txheej txheem saw
Alloy 400 tsis yog "machine-and-ship" khoom. Nws qhov kev ua tau zoo hinges ntawm yuav ua li cas casting, machining, thiab tiav kev sib cuam tshuam. Peb tsis outsource ib kauj ruam. Peb qhov chaw ISO-raws li kev tswj hwm kev nqis peev casting rau txoj hauv kev geometries-xws li lub tog raj kheej lub tog raj kheej nrog cov cua txias sib txuas-tom qab ntawd hloov mus rau 5-axis CNC machining siv cov cuab yeej carbide nrog nano-coated npoo tsim tshwj xeeb rau cov nickel-tooj liab alloys. Tsis muaj handoffs. Tsis muaj batch-rau-batch variation hauv fixturing. Tsis muaj re-clamping uas qhia txog kev ua yuam kev.
Qhov kev sib xyaw ntsug no muab peb qhov txiaj ntsig zoo:
- Microstructure tswj: Peb txheeb xyuas raws li-cam khwb cia grain qauv ntawm metallography ua ntej machining pib-tsis lees paub ntau yam uas qhia dendritic segregation, txawm tias tensile zog raws li spec.
- Dimensional nco: Peb CMMs khiav tag nrho ASME B89.1.12M-raws li kev soj ntsuam tom qab txhua qhov kev ua haujlwm - tsis yog ntawm kev kuaj zaum kawg. Peb taug qab thermal drift hla kev hloov pauv thiab them nyiaj rau cov cuab yeej hauv lub sijhawm.
- Surface kev ruaj ntseg: Rau cov khoom xws li winch center ncej chais, peb ntsuas nto roughness (Ra) * thiab * subsurface yas deformation qhov tob - tsis yog tom qab machining, tab sis tom qab kawg kev ntxhov siab-relieving tshav kub kho.
Vim li cas "Kev Cai" txhais tau tias ntau tshaj qhov tsis yog-tus qauv Geometry
Qee lub khw hu lawv tus kheej "kev cai" vim lawv lees txais PDF kos duab. Kev tsim khoom tiag tiag pib ua ntej-nrog kev xaiv cov khoom lag luam tawm tsis muaj cov ntaub ntawv qhia tawm. Alloy 400 ua tau zoo nyob rau hauv dej hiav txwv, yog - tab sis yuav ua li cas yog tias koj daim ntawv thov kuj mus ntawm -40 ° C pib thiab 120 ° C khiav hauj lwm temp? Txheem annealed Alloy 400 tuaj yeem embrittle. Peb koom tes nrog cov neeg muab ntawv pov thawj rau qhov chaw ASTM B164 mill-annealed bar nrog nruj dua intergranular corrosion test (IGC) dhau cov txheej txheem - thiab siv tau txhua qhov cua sov nrog ASTM G28A kuaj ua ntej txiav.
Peb kuj daws qhov teeb meem tsis pom ntawm daim ntawv. Piv txwv li: Ib lub twj tso kua mis European OEM tau teev tseg Alloy 400 rau lub rooj sib dhos nozzle tab sis xav tau Ra ≤ 0.4 µm ntawm cov rooj zaum hauv conical. Txheem sib tsoo nplooj chatter cim; polishing tshem tawm cov txheej txheem tseem ceeb-hardened. Peb qhov kev daws teeb meem? Hybrid electrochemical machining (ECM) rau kev tshem tawm ntau, ua raws li orbital pob zeb diamond honing nrog lub sij hawm real-time nto metrology tawm tswv yim. Lub sij hawm voj voog nce 18%, tab sis thawj-dhau tawm tau dhia los ntawm 62% mus rau 99.3%. Qhov ntawd yog tus nqi ntawm kev ua haujlwm kev cai - tsis yog kev cai kom zoo nkauj.
Traceability Koj tuaj yeem tshawb xyuas-tsis yog thov xwb
"Full traceability" txhais tau tias tsis muaj dab tsi tshwj tsis yog tias koj tuaj yeem qhib ib daim ntawv tshaj tawm thiab pom: tus lej yaj ntawm cov khoom nyoos, CNC kev pabcuam kho dua siv rau ntawm txhua qhov axis, CMM sojntsuam daim ntawv pov thawj lub sijhawm ua haujlwm tsis pub dhau 4 teev ntawm kev ntsuas, thiab tus neeg teb xov tooj ID uas tau kos npe rau kev soj ntsuam pom hauv qab 200-lux teeb pom kev zoo nrog 10 × magnification. Peb embed qhov no rau hauv peb ERP - tsis yog raws li lub checkbox, tab sis raws li ib tug daws teeb meem. Thaum tus neeg siv khoom tau tshaj tawm ntxov ntxov gasket leakage ntawm lub siab valve, peb rub lub digital ntxaib ntawm qhov ntawd, hla cov cuab yeej siv lub cav, thiab pom ib qho kev hloov pauv sab nraum lub neej pom zoo. Peb hloov nws-thiab ntxiv cov cuab yeej siv lub neej taug qab rau txhua qhov kev pabcuam Alloy 400.
Qhov kev qhuab qhia no ntsuas. Txawm hais tias koj xav tau ib qho qauv lossis 500 daim ib lub hlis twg, txhua qhov Alloy 400 feem yog nqa daim ntawv lo QR-coded txuas rau nws cov ntawv sau ua tiav: cov ntaub ntawv pov thawj, cov ntaub ntawv tshuaj xyuas, kev kho cua sov nkhaus, thiab txawm tias cov dej txias pH los ntawm lub tshuab machining.
Xaiv ib alloy 400 feem Hoobkas tsis yog hais txog kev nrhiav cov lus qis tshaj plaws-nws yog hais txog kev txheeb xyuas tus khub uas nws cov txheej txheem nruj sib phim koj lub luag haujlwm lub luag haujlwm tseem ceeb. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb kho txhua qhov Alloy 400 kev txiav txim raws li daim ntawv cog lus metallurgical: xa qhov raug qhov tseeb, khaws cia microstructural kev ncaj ncees, thiab lav kev ua haujlwm zoo - tsis yog ntawm daim ntawv, tab sis hauv thaj teb. Vim hais tias thaum koj lub kaw lus khiav ntawm 300 bar nyob rau hauv offshore tej yam kev mob, kam rau ua stacks tsis sib tham. Tsis yog peb ua.
