Thaum cov kws tshaj lij qhia cov xuab zeb-cam khwb cia hlau qhov chaw rau hydraulic systems, oilfield li qub, los yog hnyav-lub luag hauj lwm twj tso kua mis, lawv tsis tsuas yog xav tau "ib tug foundry." Lawv xav tau ib OEM xuab zeb casting Hoobkas uas kho qhov seem stability, microstructure tswj, thiab cov ntaub ntawv traceability li non-negotiable-tsis xaiv ntxiv.
Peb tau pom ntau qhov chaw nres tsheb ntawm cov qauv qauv vim tias lub tsev casting tsis tuaj yeem tuav ± 0.15 hli ntawm cov khoom siv cobalt-alloy piston vaj tse bore - los yog phem dua, xa tawm tsis sib haum AMS 5387 tensile lub zog hla cov khoom siv. Qhov ntawd tsis yog qhov teeb meem machining. Nws yog cov txheej txheem kev koom ua ke tsis ua haujlwm: casting yam tsis muaj kev qhuab qhia metallurgical, machining yam tsis paub casting-paub GD&T txhais, ua tiav yam tsis muaj kev kuaj corrosion.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm txawv. Raws li nyob rau hauv Qingdao, Tuam Tshoj, nws khiav ib qho ISO-raws li qhov chaw uas xuab zeb casting tsis cais-nws yog engineered nrog CNC machining, kev kho cua sov, thiab nto validation. Qhov tshwm sim? Castings tsim * rau * kawg ua haujlwm - tsis yog pwm puv. Piv txwv li, lawv T800 cobalt-raws li winch center ncej rollers tau tswj xyuas qhov cua txias * ua ntej * rough machining kom txo qis kev ntxhov siab-yog li hauv av kawg OD nyob hauv 0.02 hli tag nrho cov ntsuas ntsuas (TIR) hauv qab 120 MPa radial load.
Cov theem ntawm kev tswj no pib nrog raw khoom lav ris. Txhua qhov kub ntawm AMS 5387 alloy tuaj txog nrog tag nrho cov ntawv xeem ntsuas-thiab txhua qhov ntau tau txheeb xyuas qhov chaw siv OES spectroscopy ua ntej nchuav. Tsis muaj kev zam. Lawv cov hlau castings siv tau ntawv pov thawj EN-GJS-400-15 hlau hlau, tab sis qhov tseem ceeb, lawv saib xyuas cov nodularity * nyob rau lub sijhawm tiag tiag * thaum kev kho cov yaj - tsis yog tom qab nchuav. Tias yog vim li cas lawv lub hauv paus twj tso kua mis ua tiav> 92% nodularity tsis tu ncua, txawm nyob rau hauv ntu tuab dua 120 hli.
Vertical kev koom ua ke yog lawv qhov chaw ua haujlwm thib ob. Feem ntau OEMs outsource casting, machining, thiab tiav rau peb tus neeg muag khoom sib cais. QINGDAO QIANGSENYUAN ua tag nrho peb nyob rau hauv ib lub ru tsev - nrog cov ntaub ntawv sib koom ua ke, synchronized soj ntsuam raws tu qauv, thiab cov ntaub ntawv hla tebchaws sib koom ua ke. Thaum tus neeg siv khoom xa daim duab rau lub siab valve lub cev nrog lub rooj zaum nruj (± 0.05 hli rau datum A), pab pawg tsis tso tawm "ntxuav dawb" rau kev ua haujlwm. Lawv co-tsim lub rooj vag system * nrog rau qhov kawg machining teeb nyob rau hauv lub siab *, kom ntseeg tau tias riser qhov chaw tsis txhob cuam tshuam nrog cov ntsiab lus tseem ceeb fixture. Qhov no txiav rov ua haujlwm los ntawm 68% ntawm thawj tsab ntawv tsim, raws li cov ntaub ntawv 2023 sab hauv hla 142 hydraulic tivthaiv xaj.
Qee tus tuaj yeem sib cav tias xuab zeb casting tsis tuaj yeem phim peev casting rau txoj kev geometry. Tab sis nyob rau hauv kev xyaum, precision xuab zeb casting yeej qhov thermal loj teeb meem - zoo li tuab-section lub tog raj kheej vaj tse rau high-pressure piston twj. Cov qauv kev nqis peev tawm tsam nrog cov nyiaj them poob qis tshaj 80 hli phab ntsa thickness; ntsuab-xuab zeb pwm nrog lub computer-simulated solidification pub muab ntau qhov kev cia siab ntawm cov cheeb tsam ntawd. QINGDAO QIANGSENYUAN siv MAGMASOFT®-validated gating designs rau txhua qhov tshiab xuab zeb-cam khwb cia-thiab cross-checks kwv yees tias shrink kab noj hniav tiv thaiv qhov tseeb X-ray tau. Lawv cov cobalt alloy nozzles, piv txwv li, qhia xoom sab hauv porosity hauv radiographic Class B soj ntsuam, txawm nyob ntawm 110 hli phab ntsa thickness.
Dab tsi cais lawv los ntawm cov chaw tsim khoom lag luam yog qhov tshwj xeeb tshwj xeeb - tsis yog kev ua raws cai. Lawv cov txheej txheem tshuaj xyuas rau cov hlau thiab stainless hlau castings suav nrog kev kuaj ultrasonic (UT) ib ASTM E186 rau subsurface flaws, ntxiv rau kev ntsuas cov ntsiab lus ferrite rau qib duplex siv sib nqus induction. Rau cov khoom siv cobalt-nickel, lawv ntxiv kev ntsuas kev sib xyaw ua ke ntawm ASTM A262 Practice E. Thiab txhua qhov ua tiav nkoj nrog daim ntawv pov thawj qhia qhov tseeb hardness, grain loj, thiab tshuaj muaj pes tsawg leeg - tsis yog "ua tau raws li spec."
Kev xa khoom tiag tiag hauv ntiaj teb kev ntseeg raws li ib txwm muaj. Lawv cov kev npaj tsim tawm ntshiv hauv cov sij hawm ua ntej: 6-8 lub lis piam rau cov qauv, 10-12 lub lis piam rau nruab nrab-ntim khiav (50-500 pcs), tsis muaj sij hawm poob ntawm 94% ntawm kev txiav txim xa tuaj rau xyoo 2023. Qhov sib xws yog los ntawm kev faib peev txheej ruaj khov - tsis yog raws li cov khoom xaj xaj - thiab 50 MS 8, kev pom zoo ua ntej. qib.
Yog tias koj tab tom nrhiav kev cai hlau qhov chaw uas tsis ua haujlwm txhais tau tias tsis muaj sijhawm, kev pheej hmoo kev nyab xeeb, lossis kev rov qab los ntawm thaj chaw - saib dhau ntawm cov kab kos kev ua siab ntev. Nug li cas tus OEM xuab zeb casting Hoobkas validates microstructure uniformity nyob rau hauv ib tug 200 kg twj tso kua mis foundation. Nug seb lawv qhov GD&T tshuaj xyuas cov chij muaj peev xwm ua tau zoo li cas los xij * ua ntej * thawj tus qauv raug txiav. Nug yog tias lawv cov ntaub ntawv taug qab txuas mus rau tus lej xov tooj cua sov - tsis yog batch IDs xwb.
Qhov ntawd yog qhov sib txawv ntawm qhov tau txais qhov casting-thiab tau txais kev ua haujlwm, lub luag haujlwm tseem ceeb hauv kev tsim kho rau kev ua tau zoo, tsis yog daim ntawv xwb.
