Thaum cov kws tshaj lij qhia cov kev pabcuam cam khwb cia hlau xuab zeb casting Hoobkas, lawv tsis yog tsuas yog xaj cov khoom-lawv tab tom ua kom muaj kev ncaj ncees nyob rau hauv qhov siab, qhov ruaj khov nyob rau hauv lub voj voog thermal, thiab kev ntseeg ntev ntev hauv qhov chaw abrasive, kev ntxhov siab. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau nrum ntau tshaj 12,000 hlau Cheebtsam rau hydraulic valve lub cev, piston twj tso kua mis vaj tse, thiab winch center ncej chais-txhua ib tug validated tiv thaiv AMS 5387 metallurgical specs, ISO 9001 kev soj ntsuam cov neeg teb xov tooj thiab lub ntiaj teb no cov neeg tsav tsheb tiag tiag OEMs.
Dab tsi cais qhov kev ua haujlwm zoo los ntawm lub hom phiaj tseem ceeb tsis yog cov pwm nkaus xwb - nws yog cov khoom siv li cas, kev ua haujlwm siab ntev, thiab kev kho cua sov sib txuas ua ke thaum tsim khoom. Peb tau pom cov neeg siv khoom tsis lees paub qhov chaw tom qab 18 lub hlis hauv kev pabcuam - tsis yog vim qhov porosity lossis shrinkage, tab sis vim tias kev sib cais ntawm microstructural nyob rau hauv qhov rooj vag tau nrawm hnav hauv cov ntawv thov piston siab. Yog vim li cas peb cam khwb cia hlau xuab zeb casting Hoobkas tsis kho cov xuab zeb molding raws li tus txheej txheem standalone. Nws yog thawj qhov ntawm kev sib txuas ua ke ua haujlwm nruj: ntsuab-xuab zeb qauv alignment → tswj kev ua kom ruaj khov qauv → tom qab cam khwb cia kev ntxhov siab nyem ntawm 650 ° C → CNC-machined datum tsim → CMM-tuaj xyuas GD&T ua raws li qhov tseem ceeb ntawm qhov bores thiab sealing nto.
Cov neeg muag khoom feem ntau muab "sand casting." Ob peb tswj tag nrho cov saw-los ntawm cov ntaub ntawv pov thawj raw khoom mus rau qhov kawg kev xeem. Peb tsuas yog tau txais ISO 14001-certified grey hlau (GG25 / GG30) thiab ductile hlau (GJS-400-18, GJS-500-7) nrog traceable ladle qhia. Txhua batch undergoes spectrographic tsom xam ua ntej pouring. Thaum lub sij hawm molding, peb saib xyuas cov ntsiab lus noo noo (4.8-5.2%), permeability (120-140), thiab compactibility nyob rau hauv lub sij hawm-tsis nrog cov chaw kuaj, tab sis los ntawm embedded sensors nyob rau hauv peb automated mixing kab. Thiab vim hais tias cov xuab zeb nthuav dav sib txawv nrog cov av noo thiab qhov kub thiab txias, peb lub hauv paus hauv paus tswj hwm ± 2 ° C thiab 55% RH txhua xyoo. Qhov kev sib xws cia peb tuav ± 0.15 hli ntawm 300 hli OD lub tog raj kheej vaj tse-tsis muaj kev sib tsoo.
Tab sis casting precision ib leeg tsis txaus. Lub tsev nyob hauv siab tuaj yeem ua tau raws li txhua qhov kev qhia tshwj xeeb - thiab tseem ua tsis tiav ntawm 280 bar yog tias qhov kev ntxhov siab sab hauv gradients cuam tshuam lub rooj zaum saum npoo hauv qab thermal load. Qhov ntawd yog qhov kev sib koom ua ke ntsug tseem ceeb. Peb lub tuam txhab ua txhua yam hlau casting nws cam khwb cia. Tsis muaj handoffs. Tsis muaj re-fixturing. Peb siv tib lub datums rau casting qauv layout thiab CNC workholding - yog li lub tshuab sealing ntsej muag hais txog tib yam casting nto uas txias hauv pwm. Rau cobalt-alloy twj tso kua mis zoo li AMS 5387 nozzles, peb muab peev casting rau nyias-walled geometry nrog xuab zeb-cam khwb cia hauv paus-ces tiav ob qho tib si nyob rau hauv ib tug teeb ntawm peb 5-axis DMG MORI NTX 1000. Qhov tshwm sim? Nto roughness Ra ≤ 0.8 µm ntawm mating ntsej muag, xoom rework ntawm 94% ntawm thawj tsab ntawv tsim.
Peb tsis ua kom zoo rau cov nqe lus qis tshaj-peb ua kom zoo rau tus nqi qis tshaj ntawm cov tswv cuab. Qhov ntawd txhais tau hais tias kev tawm tswv yim tawm tsam qhov tsis tsim nyog T800 cobalt hloov khoom dua tshiab thaum GG30 nrog nitride hardening muab kev pabcuam vaj huam sib luag hauv lub twj tso kua mis. Nws txhais tau hais tias chij cov kaum sab xis hauv qab 0.5 ° thaum lub sij hawm kos duab-ua ntej tus qauv txiav-vim peb paub cov yam ntxwv ua rau luag, ntog kua muag, thiab tsis sib haum ejection quab yuam. Nws txhais tau hais tias xa cov ntawv ceeb toom nrog txhua qhov kev txiav txim, suav nrog tus lej xov tooj cua sov, lub zog tensile, hardness, thiab CMM scan overlays tawm tsam nominal CAD. Thaum ib tus neeg Esxias sab hnub tuaj xav tau 240 units ntawm onboard winch roller nrog 0.02 mm runout kam rau ua, peb tau xa hauv 22 hnub - tsis yog los ntawm kev nrawm, tab sis los ntawm kev xauv cov txheej txheem tsis ua haujlwm thaum lub sij hawm tsim qauv thiab rov siv dua ntawm ntim. Qhov ntawd yog qhov tseeb ntawm kev ua haujlwm nrog a cam khwb cia hlau xuab zeb casting Hoobkas tsim rau kev ua tau zoo, tsis yog kev tsim khoom xwb.
