Thaum engineers qhia a casting hlau qhov chaw Hoobkas, lawv tsis yog tsuas yog xaj khoom-lawv tab tom ua kom muaj kev ncaj ncees nyob rau hauv 300 bar hydraulic siab, qhov ruaj khov tom qab 500 ° C kev kho cua sov, lossis hnav tsis kam nyob rau hauv qhov chaw abrasive slurry. Tias yog vim li cas peb tau pom cov neeg siv khoom rov qab peb zaug rau tib tus khub: tsis yog rau tus nqi qis tshaj, tab sis rau xoom-thawj-khiav seem ntawm AMS 5387 cobalt alloy twj tso kua mis, rov ua dua GD&T ua raws li piston lub tog raj kheej bores, thiab tag nrho cov khoom traceability mus rau yaj batch thiab tensile xeem daim ntawv qhia.
Vim li cas casting hlau ib feem Hoobkas xaiv tsis tau-ua ntej machining txawm pib
Cov pab pawg muag khoom feem ntau kho casting raws li cov khoom lag luam. Lawv tsis paub tias 68% ntawm qhov tsis txaus ntseeg nyob rau hauv lub siab lub cev muaj zog yog tsim los ntawm pwm tsim - tsis yog CNC programming. Peb tau ntsuas nws: cov xuab zeb-cam khwb cia hlau vaj tsev nrog kev tswj tsis tau txias txias gradients qhia 0.042 hli bore distortion tom qab kev ntxhov siab. Kev nqis peev-cam khwb cia T800 cobalt qhov qis qis qis yog tias siv quav ciab nthuav dav tsis raug ntsuas kom haum rau cov av noo thiab ntsuas kub. Ib qhov tseeb casting hlau qhov chaw Hoobkas tsis yog tsuas yog nchuav hlau - nws daim ntawv qhia thermal loj faib, validates solidification simulation tiv thaiv microstructure tiag tiag, thiab kho cov rooj vag ua ntej thawj ncuav.
Qhov ntawd yog li cas QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. xa cov phab ntsa tuab zoo ib yam hauv 120 mm-tuab twj tso kua mis-txawm tias nyuaj sab hauv cov cua txias. Lawv cov ISO-raws li foundry khiav parallel casting thiab machining workflows. Yog li thaum tus neeg siv khoom xa daim duab kos rau qhov tsis yog tus qauv cobalt alloy nozzle, engineers cross-check casting feasibility * ua ntej * quoting: "Qhov 3.2 hli vojvoog no puas muaj sia nyob ruaj khov? Yog-peb siv cov cores ceramic thiab cov cua txias. Nws puas yuav tuav ± 0.015 hli ID kam rau ua tom qab siv? Tsis muaj kev xav. Tsuas yog metallurgical ua-thiab-zoo.
Plaub lub peev xwm uas cais cov precision casters los ntawm cov khoom muag
- Cobalt-nickel alloy mastery - tsis yog tuav, tab sis optimizing: AMS 5387 tsis machined; ua coax. Lawv lub khw siv cov cuab yeej carbide nrog 8 ° tsis zoo rake lub kaum sab xis, dej nyab lub zog ntawm 42 bar siab, thiab lub sijhawm tiag tiag kev co damping ntawm 5-axis mills. Qhov tshwm sim: nto tiav Ra ≤ 0.8 µm ntawm cov bores sab hauv ntawm cobalt alloy plugs, tsis muaj micro-cracking.
- Vertical kev koom ua ke uas tiv thaiv kev ua siab ntev stack-up: Xuab zeb casting, kho cua sov, CNC machining, thiab CMM tshuaj xyuas tshwm sim hauv ib lub ru tsev. Tsis muaj kev kho cua sov sab nraud tus neeg muag khoom hloov cov nqi hardness. Tsis muaj lwm tus neeg grinder qhia txog kev khiav tawm. Thaum lub winch center ncej cov menyuam yuav tsum tau HRC 58-62 nto hardness * thiab * 0.008 hli tag nrho qhov taw qhia nyeem ntawv (TIR), qhov linkage no tsuas muaj sia nyob kaw-voj txheej txheem tswj.
- Functional geometry dhau ntawm kev ua kom zoo nkauj: Lawv cov engineers tsis lees txais cov duab kos uas qhia meej tias "kev hloov pauv" yam tsis tau txhais cov dej coefficient lossis siab poob. Hloov chaw, lawv ua qauv ua kua dej nyob hauv thaj chaw tseem ceeb - tom qab ntawd kho cov kab hluav taws xob, cov kaum sab xis, thiab lub rooj vag qhov chaw kom ua tau raws li kev ua tau zoo, tsis yog luam tawm xwb.
- Traceability uas teb cov lus nug tiag: Tsis yog "Qhov no tau ua qhov twg?" Tab sis "Qhov twg cov khoom siv kho cua sov tau pom 12% siab dua qhov cuam tshuam ntawm −40 ° C? Tus neeg teb xov tooj twg khiav qhov kawg honing dhau ntawm ntau #QS-2291-C?" Txhua yam khoom tseem ceeb muaj QR code txuas rau cov ntaub ntawv pov thawj, cov ntawv pov thawj thermal, CMM cov ntaub ntawv, thiab cov ntaub ntawv soj ntsuam pom.
Tus nqi zais ntawm "ceev ceev, xa ceev" cog lus
Qee lub tsev cog khoom cog lus 3 lub lis piam ua haujlwm ntawm cov hlau castings. Peb tau taug qab dab tsi tshwm sim tom ntej: 22% tus nqi rov ua haujlwm ntawm lub siab li qub vim qhov tsis pom qhov pom ntawm qhov porosity; 3.7 hnub nruab nrab ncua sij hawm thaum kho cua sov qhia qhov tsis sib xws hardness; $ 18,000 hauv huab cua thauj khoom los hloov ib lub piston twj tso kua mis tsis muaj vaj tse uas tsis ua haujlwm.
QINGDAO QIANGSENYUAN tsis ua kom zoo rau daim ntawv qhia hnub ceev. Lawv optimize rau * thawj zaug-txoj cai ua*. Lawv cov kev npaj tsim khoom tsim muaj xws li kev ntsuam xyuas kev pheej hmoo ua ntej: "Qhov no puas yuav 17-4PH stainless casting distort thaum lub sij hawm kev daws teeb meem annealing? Yog - yog li peb ntxiv cov kev ntxhov siab - ua ntej * zaum kawg machining." Lawv cov kev ua haujlwm ntshiv txhais tau tias tsis muaj lub hauv paus ntawm kev tshuaj xyuas - CMMs khiav 24/7, nrog cov ntawv tshaj tawm tsis siv neeg sib txuas rau ERP. Cov qauv xaj xaj xa nkoj hauv 18 hnub - tsis yog vim lawv maj, tab sis vim tias lawv tshem tawm cov voj voog rov ua haujlwm ntxov.
Yuav ua li cas txheeb xyuas - ua ntej koj kos npe rau PO
Nug koj casting hlau qhov chaw Hoobkas tsib lo lus nug no—thiab thov cov ntaub ntawv pov thawj:
- "Qhia kuv peb tsab ntawv tshaj tawm CMM kawg rau ib feem cuam tshuam nrog peb GD&T callouts-tshwj xeeb tshaj yog cov profile thiab txoj hauj lwm kam rau ua."
- "Muab lub cav yaj thiab cov ntawv ntsuas tensile rau cov cobalt alloy batch siv hauv koj qhov kev txiav txim AMS 5387 tsis ntev los no."
- "Yuav ua li cas koj validate solidification simulation tiv thaiv qhov tseeb microstructure? Qhia ib tug ntoo khaub lig-section duab nrog dendrite arm spacing ntsuas."
- "Dab tsi yog koj qhov siab tshaj plaws kev sib txawv ntawm qhov ntev li-cam khwb cia thiab qhov kawg-machined qhov ntev rau 300 hli txoj kab uas hla hlau castings?"
- "Thaum daim duab qhia txog 'kev sim tsis muaj kev puas tsuaj rau ASTM E186', cov neeg ua haujlwm twg tuav daim ntawv pov thawj ASNT Qib II tam sim no - thiab thaum twg yog lawv qhov kev xeem ua ntej kawg?"
Cov no tsis yog theoretical checks. Lawv yog cov ntxaij lim dej uas nthuav tawm seb tus neeg muag khoom puas ua haujlwm casting li engineering - lossis raws li kev kwv yees.
Ib tug txhim khu kev qha casting hlau qhov chaw Hoobkas tsis muag qhov chaw. Nws muag kev kwv yees. Nws tau lees tias lub pob zeb cobalt nozzle yuav tsis yaig ntawm 12 m / s slurry tshaj tawm. Tias cov hlau casting tuav 0.02 hli flatness hla 800 hli tom qab thermal cycling. Tias txhua qhov kev xa khoom tuaj txog nrog cov ntaub ntawv - tsis yog cov ntaub ntawv xwb. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. tsim kom muaj kev ntseeg siab rau hauv nws cov txheej txheem architecture, tsis yog nws li kev lag luam. Vim hais tias nyob rau hauv hydraulic systems, oilfield khoom, thiab engineered tsheb platforms, tsis muaj ob lub caij nyoog rau qhov seem tsis ua hauj lwm.
