Kev pabcuam hlau casting tsis yog tsuas yog nchuav hlau molten rau hauv pwm. Nws yog hais txog kev tuav qhov ntev ntev nyob rau hauv ± 0.05 hli ntawm 300-mm hlau twj tso kua mis vaj tse thaum ua kom cov microstructural uniformity hla 120-kg batch-hauv siab, hnav, nyob rau hauv kev tshuaj xyuas. Qhov ntawd yog lub hauv paus peb ua haujlwm los ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.—tsis yog tus neeg muag khoom, tab sis raws li tus txheej txheem koom nrog hauv hydraulic system tsim cycles, oilfield khoom siv tau, thiab engineering tsheb winch los ua ke kab.
Vim li cas Hlau Casting Kev Pabcuam Tsis Ua Haujlwm Thaum Precision Tsis Ua Haujlwm Hauv
Peb tau pom peb hom kev ua tsis tiav - tsis yog los ntawm kev ua haujlwm tsis zoo, tab sis los ntawm kev cia siab tsis raug. Ua ntej: piv txwv tias "grey hlau" txhais tau tias ib yam khoom. Tsis yog. ASTM A48 Chav Kawm 30B, EN-GJL-250, thiab ISO 185-200 txhua qhov sib txawv rau thermal cycling thaum lub tshuab ua haujlwm - thiab tsuas yog ib qho xa tawm lub peev xwm damping xav tau rau piston twj tso kua mis lub tog raj kheej ua haujlwm ntawm 350 bar. Thib ob: kho casting raws li cov kauj ruam standalone. Nyob rau hauv qhov tseeb, xuab zeb-cam khwb cia hlau qhov chaw destined rau CNC xov yuav tsum tau lub kaum sab xis, gating nyiaj, thiab riser qhov chaw uas ncaj qha cuam tshuam rau tom qab machining distortion. Peb ib zaug rov ua dua 17 lub cev lub cev vim tias tus qauv qub tsis suav nrog kev txo qis anisotropy hauv high-phosphorus grey hlau - raug nqi 11 hnub thiab $ 8,400 hauv seem thiab rov ntsuas dua. Thib peb: hla metallurgical traceability. Ib tus neeg siv khoom nyob sab Europe tsis lees txais tag nrho cov khoom xa tuaj - tsis dhau qhov ntev, tab sis vim tias lub log log tsis muaj cov xov tooj cua kub sib txuas rau cov ntaub ntawv ntsuas tensile. Peb tam sim no tag txhua ncuav nrog QR-coded batch phaib khi rau spectrometer tso zis, txias tus nqi nkhaus, thiab hardness mapping cov ntaub ntawv.
Qhov twg Hlau Casting Service ntsib Real-World Load Case
Peb cov kev pabcuam hlau casting tsom rau plaub pawg ua haujlwm-tsis yog qib alloy lossis hom txheej txheem. Siab li qub xav kom nruj sealing nto thiab qaug zog-resistant microstructures. Lub hauv paus twj tso kua mis yuav tsum nqus kev co yam tsis muaj resonant amplification ntawm 1,750 rpm. Lub tog raj kheej vaj tse yuav tsum tau bore concentricity <0.03 hli hla 450 hli ntev tom qab kev kho cua sov. Winch center shaft rollers xav tau qhov hardness ≥240 HBW nrog cov ntaub ntawv qhov tob ntawm 8-12 mm-tsis muaj decarburization ntawm lub interface. Rau cov no, peb siv hloov pearlitic grey hlau (ASTM A48 Chav Kawm 40) nrog tswj Mn / Si ratios thiab inoculated nrog FeSi75 + CaAl hlau los suppress hom D graphite. Qhov tshwm sim? A 22% txo qis hauv lub sijhawm ua haujlwm piv rau tus qauv A25, thiab xoom teb tsis ua haujlwm ntawm 14,300+ units xa mus rau North American hydraulic OEMs txij li xyoo 2021.
Dab tsi Vertical Integration Tiag Delivers—Tshaj Tawm Kev Ua Lag Luam
Feem ntau cov chaw muag khoom outsource casting, machining, lossis xov. Peb tswj tag nrho peb-hauv ib lub chaw ISO 9001: 2015-tso ntawv pov thawj. Qhov ntawd txhais tau hais tias tsis muaj kev sib koom tes ntawm cov neeg muag khoom thaum lub cobalt-alloy plug (AMS 5387) xav tau kev sib tsoo zoo * tom qab * peev casting, lossis thaum T800-raws li lub twj tso kua mis yuav tsum muaj kev ntxhov siab rau kev ntxhov siab * ua ntej * kev soj ntsuam CMM zaum kawg. Tshwj xeeb, peb cov haujlwm ua haujlwm embeds: cov khoom siv raw khoom pov thawj ntawm OES spectrometry; Kev kuaj xyuas hauv kev siv Zeiss CONTURA G2 CMMs calibrated rau ISO 10360-2; thiab kev sim ua haujlwm zaum kawg - suav nrog hydrostatic siab tuav ntawm 1.5 × ua haujlwm siab rau 30 feeb ntawm txhua lub cev valve. Traceability tsis yog ib daim ntawv tshaj tawm-nws yog cov ntaub ntawv nyob txuas txuas txhua qhov ua tiav rau nws qhov tseeb yaj chemistry, solidification nkhaus, thiab nto roughness Ra tus nqi ntsuas los ntawm Taylor Hobson Form Talysurf.
Xaiv Txoj Cai Hlau Casting Kev Pabcuam Tus Tswv Cuab-tsib Daim Ntawv Teev Tsis Sib Tham
- Nug rau qhov tseeb GD&T callouts ntawm cov qauv castings- tsis yog "± 0.3 hli." Yog tias lawv tsis tuaj yeem pom qhov ua siab ntev ntawm Ø12.5H7 bore txheeb ze rau datum A-B-C ntawm daim duab ntau lawm, taug kev mus.
- Xav tau cov ntaub ntawv pov thawj ntawm kev sib koom ua ke ntawm kev kho cua sov. Grey hlau rau cov twj tso kua mis feem ntau xav tau normalizing. Puas yog lawv lub qhov cub puas muaj qhov programmable ramp / soak / txias profiles nkag rau ib pawg? Los yog nws yog "qhov cub teeb thiab tsis nco qab"?
- Tshawb xyuas cov ntaub ntawv pov thawj qhov tob. Daim ntawv qhia txog zeb xeem (MTR) yog rooj ceg txheem ntseeg. Tag nrho cov traceability txhais tau tias cov xov tooj cua kub stamped rau ntawm ib feem, txuas rau ladle tsom xam, tensile tuav kuaj ib ASTM E8, thiab microstructure dluab archived.
- Ntsuam xyuas lawv manufacturability tswv yim. Xa lawv ib daim duab nrog nyias phab ntsa tav (2.8 hli tuab, 120 hli ntev). Tus khub tiag tiag taw qhia txog kev hloov pauv tseem ceeb thiab qhia txog kev hloov pauv ntawm lub vojvoog ua ntej siv-tsis yog tom qab thawj tsab ntawv tsis lees paub.
- Paub meej tias kev qhuab qhia ntawm kev xa khoom ntawm qhov nruab nrab-ntim khiav. Prototypes yooj yim. Lawv puas tuaj yeem xa 420 lub siab valve lub cev hauv lub lim tiam 6, lub lim tiam 7, thiab lub lim tiam 8 - tib hnub, tib lub pallet teeb tsa, tib daim ntawv lo? Kev sib raug zoo yeej ceev txhua lub sijhawm.
Cov kev pabcuam hlau casting ua tiav qhov chaw metallurgy, geometry, thiab daim ntawv thov physics cuam tshuam - tsis yog qhov twg cov catalogs kawg. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb kho txhua qhov casting raws li lub nra hnyav ntawm qhov loj dua. Vim tias kev ntseeg tsis raug pov tseg. Nws yog engineered, txheeb xyuas, thiab xa-batch tom qab batch, xyoo tom qab xyoo. Rau lub hom phiaj tseem ceeb ntawm kev pabcuam hlau casting, pib nrog qhov yuav tsum tau ua - tsis yog qhov txheej txheem tuaj yeem ua tau.
