Thaum lub twj tso kua mis hydraulic lub tsev tawg nyob rau hauv 350-bar siab-los yog cobalt-alloy nozzle ua tsis tiav tom qab 420 teev ntawm qaub-gas kev pab cuam - qhov teeb meem tsis yog ib feem tsis ua hauj lwm. Nws yog qhov tsis sib xws ntawm kev muaj peev xwm casting thiab kev xav tau ua haujlwm. Qhov kev tsis sib haum no pib ntev ua ntej cov pwm tau nchuav: ntawm kev sib tshuam ntawm cov khoom siv tshawb fawb, kev tswj qhov loj me, thiab lub ntiaj teb kev thauj khoom tiag tiag. Rau cov kws tshaj lij qhia cov khoom hauv cov roj & roj, mobile hydraulics, lossis cov twj tso kua mis siab, xaiv txoj cai hlau castings Hoobkas txhais tau tias xaiv ib qho uas kho metallurgy li engineering - tsis yog melting thiab pouring.
Vim li cas "Precision Casting" tsis yog ib lo lus lag luam xwb
Peb tau pom ntau txoj haujlwm qeeb los ntawm qhov chaw uas dhau qhov kev tshuaj xyuas thawj zaug tab sis warp thaum kho cua sov-los yog ua tau raws li qhov loj me me tseem tsis tau ua rau qaug zog vim tias cov qauv nplej tsis tau saib xyuas thoob plaws lub ncuav. Qhov tseeb precision casting xav tau kev sib koom ua ke ntsug: tswj cov ntaub ntawv pov thawj raw khoom, kev ua qauv zoo, kev tsim kho tshuab, thiab kev ntxhov siab tom qab nrum - tag nrho hauv ib lub ru tsev. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., txhua AMS 5387 cobalt alloy twj tso kua mis tsev pib nrog traceable T800-qib ingot, txheeb xyuas ntawm PMI thiab OES ua ntej remelting. Tsis muaj batch ua tau yam tsis tau lees paub cov ntsiab lus carbon ± 0.02%, chromium variance <0.15%, thiab kev sib cais interdendritic hauv qab ASTM E1268 Class B txwv.
Qhov no tsis yog kev ua raws li theoretical. Nyob rau hauv ib txoj haujlwm OEM North American, peb tau txheeb xyuas micro-shrinkage nyob rau hauv lub valve lub rooj hloov chaw siv X-ray CT - tom qab ntawd kho qhov nrawm nrawm thiab nce qhov chaw tso tawm kom tshem tawm nws. Qhov tshwm sim? Zero rework hla 1,280 units. Precision casting ntawm no txhais tau hais tias qhov ntev ntawm qhov rov ua dua nyob rau hauv ± 0.05 hli ntawm qhov tseem ceeb bores * thiab * cov khoom siv kho tshuab tuav tsis pub dhau 3% ntawm spec thoob plaws tag nrho cov kev khiav haujlwm - tsis yog ntawm daim coupon no xwb.
Qhov twg Sand Casting ntsib CNC Kev muaj tiag
Qee cov neeg muag khoom cais cov casting thiab machining rau hauv cov chaw ua haujlwm siled. Uas tsim qhov muag tsis pom kev. Cov xuab zeb-cam khwb cia hlau twj tso kua mis lub hauv paus yuav tuav GD & T txoj hauj lwm kam rau ua-tab sis tsuas yog kom txog thaum machining-induced residual stress distorts lub mounting nto. QINGDAO QIANGSENYUAN daws qhov no los ntawm kev sib koom ua lag luam thiab cov xuab zeb casting kab nrog ntau-axis CNC hlwb. Lawv cov engineers tshuaj xyuas koj daim duab tsis yog "peb puas tuaj yeem pov nws?" tab sis "peb yuav ua li cas peb nrum nws thiaj li zaum kawg machining khaws cia cov qauv kev ncaj ncees?"
Piv txwv li: piston twj tso kua mis lub tog raj kheej vaj tse yuav tsum bore concentricity ≤0.03 hli tshaj 450 hli ntev. Lawv cov kev daws teeb meem sib txuas cov kev taw qhia ua kom muaj zog hauv silica-bonded pwm nrog kev ua haujlwm CMM pov thawj ntawm peb theem - ua ntej machining, tom qab roughing, thiab tom qab tiav. Kev kho cua sov (yog tias tau teev tseg) tshwm sim hauv lub tshuab nqus tsev nrog lub sijhawm ua haujlwm ntawm lub thermocouple, kom ntseeg tau tias muaj kev sib txawv ntawm cov phab ntsa thickness ntawm 12 hli mus rau 85 hli.
- Hlau castings: ASTM A48 Chav Kawm 30B txog 65B, nrog nodularity> 85% txheeb xyuas rau ISO 945
- Stainless hlau castings: ASTM A743 CF8M / CF3M nrog cov ntsiab lus ferrite 5-12% ntsuas ntawm Feritscope
- Cobalt-nickel Cheebtsam: AMS 5387 tau ntawv pov thawj, nrog Rockwell C 42-48 thiab Charpy V-notch ≥25 J ntawm -40 ° C
Qhov "Reliable" Tiag tiag txhais tau tias hauv kev xyaum
Kev ntseeg siab tsis tau lees paub los ntawm ISO 9001 ib leeg. Nws tau tsim nyob rau hauv kev tsim ua haujlwm. Thaum ib tus neeg muag khoom nyob sab Europe xav tau 220 units ntawm qhov tsis yog tus qauv winch center ncej chais-T800 alloy, 1,240 mm ntev, nrog cuam tshuam splines thiab hardened bearing phau ntawv xov xwm - pab neeg no tsis yog hais txog lub sij hawm txhuas. Lawv tau khiav kev tshuaj xyuas kev tsim khoom: flagged muaj peev xwm sib tham nyob rau hauv spline milling vim qhov sib piv, thov lwm txoj kev toolpath sequencing, thiab validated deflection nrog finite element simulation pre-cut.
Qhov ntawd yog kev ntseeg tau: tsis muaj qhov xav tsis thoob ntawm Thawj Tshooj Kev Tshawb Fawb. Tag nrho cov traceability suav nrog ntau tus lej ntawm txhua daim ntawv pov thawj ntawm kev sib raug zoo, ntxiv rau cov ntaub ntawv digital txuas rau txhua qhov sib txuas rau nws cov cav yaj, cov kab hluav taws xob kho cua sov, thiab CMM daim ntawv tshaj tawm. Yog tias tus neeg siv khoom thov cov ntaub ntawv seem rau ib chav tsev tshwj xeeb xa tawm hauv Q3 2023, nws tuaj yeem rov qab tau hauv qab 90 vib nas this - tsis yog "hauv 5 hnub ua haujlwm."
Xaiv Tshaj Tawm Ntawm Phau Ntawv Qhia
Nug ib tus neeg saib xyuas kev yuav khoom tuav lub luag haujlwm tseem ceeb: tus nqi loj tshaj plaws tsis yog tus nqi - nws yog lub sijhawm poob thaum hloov pauv tuaj txog lig lossis ua tsis tiav ntxov. Yog li saib yav dhau los glossy catalogs. Nug es tsis txhob:
- Koj puas tuaj yeem muab cov ntaub ntawv PPAP tsis ntev los no rau AMS 5387 tivthaiv hauv geometry zoo sib xws?
- Yuav ua li cas koj validate microstructure uniformity nyob rau hauv tuab seem?
- Dab tsi yog koj qhov nruab nrab thawj-dhau tawm los ntawm txoj kev nyias-walled castings?
- Koj puas ua qhov kev sim ua haujlwm - zoo li hydrostatic siab tuav ntawm 1.5 × ua haujlwm siab - rau txhua pawg?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. teb yog rau tag nrho plaub-nrog pov thawj, tsis tau cog lus. Lawv lub zog tsis nyob hauv qhov ntsuas, tab sis hauv kev tshwj xeeb: kev paub tob tob hauv cov twj tso kua mis, hydraulic vaj tse, thiab cov khoom siv hnyav hnyav - thiab cov txheej txheem sib xyaw kom xa lawv yam tsis muaj kev cuam tshuam.
Rau cov kws tsim khoom uas tau poob suav ntawm kev rov tsim dua tshiab los ntawm kev cuam tshuam txog kev cuam tshuam - lossis pab pawg neeg yuav khoom nkees ntawm kev caum cov hnub xa khoom - kev ntseeg siab pib nrog hlau castings Hoobkas uas pom ib feem raws li ib tug system, tsis yog ib tug duab. Qhov ntawd yog qhov uas precision manufacturing khwv tau nws qhov hnyav.
