Thaum engineers qhia steel casting kev pab cuam, lawv tsis yog tsuas yog xaj ib feem-lawv tab tom ua kom muaj kev ncaj ncees nyob rau hauv lub siab, qhov ruaj khov tom qab cua sov, thiab lub sij hawm ntev tiv thaiv kev yaig hauv hydraulic li qub lossis lub twj tso kua mis. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau nrum ntau dua 12,000 hlau thiab stainless hlau Cheebtsam rau lub hom phiaj tseem ceeb daim ntawv thov-txhua tus validated tiv thaiv AMS 5387 tensile specs, ISO 8062 geometric tolerances, thiab cov neeg siv-txhais kev soj ntsuam raws tu qauv.
Feem ntau cov neeg yuav khoom xav tias tag nrho cov hlau castings coj zoo ib yam. Lawv tsis ua. Peb ib zaug tau txais ib daim duab kos rau lub piston twj tso kua mis lub tog raj kheej vaj tse nrog ± 0.05 hli phab ntsa tuab kam rau ua - thiab nrhiav pom cov khoom qub spec (A105) tsis tuaj yeem xa cov microstructure zoo ib yam hla 45 kg seem. Peb tau thov ASTM A352 LCB hloov pauv: cov pa roj carbon tsawg dua, nruj dua lis tswj, txheeb xyuas los ntawm kev tshuaj xyuas ntawm cov khoom siv spectrographic. Qhov no tau dhau los kuaj hydrostatic ntawm 1.5 × ntsuas siab. Qhov ntawd tsis yog kev hloov pauv. Qhov ntawd yog metallurgical accountability.
Peb steel casting kev pab cuam txuas txuas peb qhov khoob ntawm lwm tus tawm qhib: tsim qhov ua tau, txheej txheem txuas ntxiv, thiab batch-rau-batch kwv yees. Peb khiav ob qho tib si xuab zeb thiab peev casting - tab sis yeej tsis kho lawv li kev sib hloov. Xuab zeb casting ua haujlwm hnyav txog li 350 kg nrog kev tswj kom txias rau cov tuab-section valve lub cev. Kev nqis peev casting muab ± 0.1 hli linear raug ntawm nyias-walled cobalt-alloy nozzles qhov twg machining ib leeg yuav txaus ntshai micro-cracking. Txhua pwm yog digitally pov thawj tiv thaiv CAD ua ntej pouring; txhua lub ncuav log suav nrog melt kub, superheat, thiab ladle sampling data. Tsis muaj kev xav. Tsuas yog traceable inputs.
Peb pom plaub qhov kev ua tsis tiav rov ua dua tshiab hauv kev yuav khoom steel-thiab peb tiv thaiv txhua qhov:
- Dimensional drift thaum kho cua sov: Peb koom ua ke txo kev ntxhov siab thiab tshem tawm ncaj qha rau hauv peb lub sijhawm ua haujlwm-tsis yog ib qho ntxiv. Rau T800-raws li winch center ncej chais, peb tuav qhov chaw ntawm 920 ° C rau 4 teev ua ntej machining, tom qab ntawd rov xyuas cov bores tseem ceeb nrog cov ntsuas cua ua ntej kawg CNC hla.
- Tsis sib xws nto tiav ntawm machined castings: Peb txoj kev sib koom ua ke ntsug txhais tau tias tib tus neeg teb xov tooj uas tshuaj xyuas qhov zoo li-cam khwb cia kuj ua haujlwm rau 5-axis zeb. Tsis muaj tes tuav. Tsis txhais lus poob. Nto roughness nyob twj ywm hauv Ra 0.8 µm ntawm lub ntsej muag sealing-txawm tias ntawm 316L stainless hlau nrog 22% chromium.
- Cov ntaub ntawv pov thawj qhov khoob: Peb tsuas yog los ntawm cov mills nrog EN 10204 3.1 daim ntawv pov thawj - thiab khaws tag nrho cov traceability mus rau lub tshav kub kub stamped ntawm txhua qhov chaw. Yog tias koj pab pawg QA thov cov ntawv xeem ntsuas rau ib lub cev valve xa tuaj rau xyoo 2023, peb khaws nws hauv qab 90 vib nas this.
- GD&T misalignment ntawm daim duab thiab casting: Peb siv tau txhua qhov GD&T callout thaum lub sij hawm tshuaj xyuas engineering - tsis yog "peb tuaj yeem ua tau," tab sis "cov ntaub ntawv no puas yuav muaj sia nyob thermal contraction?" Rau siab valve flanges, peb hloov cov thawj datums rau machined nto tom qab-casting, tsis txhob cia siab rau raws li-cam khwb cia nta uas txawv ± 0.3 hli.
Qee tus tuaj yeem sib cav tias kev ua haujlwm sab nrauv tsis muaj kev teb. Tab sis thaum European OEM xav tau rau tus qauv AMS 5387 twj tso kua mis nyob hauv 18 hnub - ua tiav nrog NDT, hardness mapping, thiab seem CMM cov ntaub ntawv - peb xa. Yuav ua li cas? Vim tias peb qhov kev npaj tsim khoom pib nrog lub sijhawm ua khoom siv, tsis yog hnub tim. Peb khaws 12 qib ntawm cov ntawv pov thawj steel ingots. Peb khaws cov qauv casting rau saum-10 rov ua dua qhov chaw ntawm qhov chaw. Thiab peb muab ib qhov project engineer los ntawm kev tsocai rau cov khoom xa tuaj - tsis yog ib daim ntawv teev npe.
Qhov no tsis yog hais txog scale. Nws yog hais txog kev qhuab qhia. Peb ISO 9001: 2015 system yuav tsum tau muaj ntaub ntawv soj ntsuam ntawm xya txheej txheem rooj vag: raw khoom txais, pwm los ua ke, ncuav npaj, shakeout, pov thawj kho cua sov, pre-machining CMM, thiab zaum kawg functional xeem. Txhua daim ntawv tshaj tawm txuas rov qab mus rau tus lej ua haujlwm tshwj xeeb. Txhua qhov sib txawv ua rau lub hauv paus ua rau lub cav - tsis yog kev kho, tab sis kev hloov kho cov txheej txheem. Xyoo tas los, qhov kev qhuab qhia no tau txiav thawj tsab ntawv tsis lees paub los ntawm 63% rau North American hydraulic cov neeg siv khoom.
Saib ua ntej, peb tab tom tob tob ob lub peev xwm uas redefine dab tsi steel casting kev pab cuam ua tau. Ua ntej: hybrid casting-machining. Peb tam sim no embed machined nrhiav cov yam ntxwv ncaj qha rau hauv cov xuab zeb pwm - tshem tawm qhov teeb meem thib ob ntawm lub ntsej muag twj tso kua mis ntau lub hauv paus. Thib ob: kev twv ua ntej casting simulation. Siv MAGMAsoft thermal qauv, peb txheeb xyuas qhov kub thiab txias ua ntej nchuav-txo qhov hnyav nce mus txog 28% yam tsis muaj lub suab nrov.
Yog tias koj cov hlau tom ntej no xav tau ntau dua qhov kev ua raws li qhov loj me - yog tias nws yuav tsum muaj sia nyob 10,000 lub voj voog ntawm 250 bar, foob tiv thaiv abrasive slurry, los yog tuav lub zog qaug zog tom qab 500 ° C thermal cycling - ces pib nrog lub hom phiaj metallurgical, tsis yog geometry xwb. Mus ntsib https://www.tsingtaocnc.com thov kev tshuaj xyuas kev tsim khoom pub dawb. Nqa koj GD&T, koj qhov nkhaus nkhaus, koj qhov kev ua tsis zoo yav dhau los. Peb yuav qhia koj txog qhov ua tau - thiab qhov tsim nyog qhia txawv.
