Thaum engineers qhia machined hlau casting rau hydraulic li qub, twj tso kua mis vaj tse, los yog winch shafts, lawv tsis yog tsuas yog xaj ib feem-lawv tau cog lus rau qhov kev ruaj ntseg nyob rau hauv 350-bar siab, microstructural kev ncaj ncees tom qab thermal cycling, thiab nto tiav uas tiv taus abrasive hnav nyob rau hauv cov xuab zeb-laden roj ntws. Peb tau pom ntau txoj haujlwm kaw thaum cov neeg muag khoom kho cov hlau casting raws li cov khoom lag luam - tom qab ntawd tso tawm cov khoom siv rau lub khw thib peb nrog kev txhais lus GD&T tsis sib haum, cov ntaub ntawv kho cua sov tsis sib haum, lossis tsis muaj kev taug qab rau ASTM A48 Class 350 cov khoom siv.
Vim li cas Machined Iron Casting Fails—Thiab Dab Tsi Ua Haujlwm
Hlau casting ib leeg tsis lav kev ua haujlwm. Grey hlau cov graphite flakes muab damping tab sis txo tensile zog; ductile hlau lub spheroidal graphite txhim kho toughness tab sis xav tau meej nodularization tswj thaum lub sij hawm ncuav. Ntxiv CNC machining - thiab koj qhia txog cov kev ua tsis tiav tshiab: qhov seem ntawm kev ntxhov siab cuam tshuam los ntawm qhov tsis sib xws ntawm qhov txias txias, chatter cov cim ntawm lub tog raj kheej kheej kheej kheej kheej, lossis cov tawv tawv tawv uas ua rau cov cuab yeej ua ntej hnav thaum kawg ua tiav.
Peb ib zaug rov ua dua ib pawg ntawm piston twj tso kua mis lub tog raj kheej lub tsev vim tias lub hauv paus siv cov khoom siv rov ua dua yam tsis muaj kev tshuaj xyuas spectral. Qhov tshwm sim ntawm silicon variation hloov hardness ntawm 220-240 HB mus rau 265 HB nyob rau hauv ib cheeb tsam - txaus rau deflect 0.012 hli thaum lub sij hawm tas tho txawv. Tias yog vim li cas peb sim txhua qhov yaj nrog OES tsom xam * ua ntej * nchuav - thiab txheeb xyuas qhov nyuaj tom qab cam khwb cia ntawm peb qhov chaw ntawm ib qho kev casting, tsis yog ib qho xwb.
Kev vam meej tiag tiag hauv ntiaj teb hinges ntawm kev sib koom ua ke ntsug. Foundry, tshuab khw, thiab metrology yuav tsum qhia ib tug thermal keeb kwm cav, ib CMM program, ib daim ntawv pov thawj khoom. Tsis muaj handoffs. Tsis muaj kev xav txog "tus qauv" machining nyiaj pub dawb. Thaum tus neeg siv khoom xa tuaj rau peb AMS 5387 cobalt alloy plug daim duab nrog ± 0.005 hli txoj hauj lwm kam rau ntawm rau lub qhov dowel, peb teb tsis pub dhau 48 teev - tsis yog nrog ib qho kev tsocai, tab sis nrog daim ntawv qhia txog kev tsim khoom uas qhia qhov twg EDM drilling ntaus twist drilling, qhov twg kev ntxhov siab-relieving ua ntej roughing tiv thaiv bore ovality, thiab yuav ua li cas peb siv tau ib puag ncig. cua-cov kabmob spindle.
Plaub Tsis-Tshaj Tawm rau Lub Hom Phiaj-Critical Hlau Castings
- Cov ntaub ntawv traceability mus rau lub tshav kub tooj- tsis yog tsuas yog cov ntawv pov thawj zeb, tab sis tag nrho OES cov ntawv ceeb toom, tensile test bars archived per lot, thiab microstructure duab txheeb xyuas tawm tsam ASTM E112
- Machining tom qab kev ntxhov siab-peb tuav cov castings ntawm 550 ° C rau 4 teev, tom qab ntawd txias ntawm ≤30 ° C / teev ua ntej kev tshem tawm hlau pib
- GD&T-kev tshuaj xyuas thawj zaug-CMM niaj hnub ua los ntawm cov neeg siv khoom kos duab, tsis yog cov qauv siv dav dav; datum nta probed ua ntej, ua hauj lwm nto kawg
- Surface integrity validation- tsis yog Ra qhov tseem ceeb, tab sis kev tshawb nrhiav cov txheej txheem dawb ntawm SEM / EDS rau qhov tseem ceeb ntawm kev sib khi ntsej muag raug rau H2S kev pabcuam
Qhov twg Standard Suppliers poob luv luv (Thiab Yuav Ua Li Cas Pom Nws)
Qee cov neeg muag khoom tshaj tawm "precision machined hlau casting" tab sis outsource casting rau cov khoom siv qis uas tsis muaj ISO 9001: 2015 Clause 8.5.2 tswj rau cov khoom tsis sib haum. Lwm tus siv cov kev pabcuam CNC uas suav tias yog cov nyiaj them poob haujlwm-tsis quav ntsej li cas xuab zeb casting variations cuam tshuam rau phab ntsa thickness hauv cov geometry nyuaj xws li engineering tsheb winch center ncej chais.
Peb tau ntes qhov sib txawv no thaum lub sijhawm tshawb xyuas tsis ntev los no: tus neeg sib tw tau hais txog lub siab lub cev lub cev nrog 12-mm tsawg kawg nkaus phab ntsa tuab-tab sis lawv cov duab kos pom tsuas yog 8-mm nominal nyiaj pub dawb. Hauv kev xyaum, 30% ntawm qhov yuav tsum tau muaj kev sib txuas ua ntej machining tuaj yeem pib. Qhov ntawd tsis yog precision. Qhov ntawd yog kev kwv yees disguised li muaj peev xwm.
Nug koj tus neeg muag khoom cov lus nug no ua ntej tso POs:
- Koj puas tuaj yeem qhia kuv qhov kawg peb lub cav yaj rau ASTM A ductile hlau?
- Dab tsi yog koj qhov kev tso cai ntau tshaj qhov sib txawv ntawm qhov hnyav li-cam khwb cia thiab qhov kawg-machined qhov hnyav rau 42-kg twj tso kua mis?
- Koj cov ntaub ntawv CMM puas suav nrog cov ntaub ntawv thermal drift them nyiaj nkag thaum lub sijhawm tshuaj xyuas 8 teev?
Kev ntseeg siab—tsis yog cov khoom xwb
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. xa machined hlau casting cov kev daws teeb meem uas kev ntseeg siab tsis yog sib tham - tsis yog vim peb thov nws, tab sis vim peb cov txheej txheem tawm pov thawj. Txhua lub siab valve nkoj nrog QR-coded daim ntawv txuas mus rau nws daim ntawv tshuaj ntsuam xyuas tag nrho: cov ntaub ntawv pov thawj raw khoom, cov kab kos kho cua sov, CMM taw tes huab, thiab daim ntawv qhia qhov chaw roughness. Cov neeg siv khoom hauv North America thiab Europe siv cov ntaub ntawv no rau ASME Tshooj VIII Tshooj UG-120 kev soj ntsuam kev ua raws cai. Cov neeg Esxias sab hnub tuaj OEMs hais txog lawv thaum APQP Theem 3 tshuaj xyuas.
Peb tsis caum ntim. Peb tsom mus rau qhov chaw uas tsis ua hauj lwm txhais tau hais tias tsis ua hauj lwm, kev pheej hmoo ntawm kev nyab xeeb, lossis kev nplua-zoo li T800 cobalt-based nozzles tuav 450 ° C molten ntsev hauv cov nroj tsuag hnub ci. Nyob ntawd, 0.02-mm bore taper tsis yog "kev sib txawv me me." Nws yog qhov tsis txaus txaus uas ua kom yaig los ntawm 300%.
Lub neej yav tom ntej belongs rau cov txheej txheem hybrid: peev-cam khwb cia ze-net duab nrog CNC-machined sealing av, xuab zeb-cam khwb cia vaj tsev nrog kev sib xyaw ua ke ntawm cov dej txias ua tiav los ntawm kev kub ceev milling. Peb tab tom nthuav peb R & D ntawm kev tswj-txias casting pwm thiab txhim kho nyob rau hauv-txoj kev vibration xyuas rau real-time chatter nrhiav kom tau thaum lub sij hawm sib sib zog nqus-qhov tho txawv ntawm lub tog raj kheej blocks.
Yog tias koj qhov project tom ntej xav tau machined hlau casting uas tuav qhov tseeb ntawm 300 ° C, muaj sia nyob 10⁶ lub voj voog siab, thiab tuaj txog nrog xoom qhov xav tsis thoob - pib nrog cov khoom siv taug qab, tsis yog nqi ib kilogram.
