Thaum engineers qhia a hlau casting Hoobkas rau lub hom phiaj tseem ceeb hydraulic li qub los yog cov twj tso kua mis siab, lawv tsis yog tsuas yog yuav cov khoom-lawv yog outsourcing seem stability, microstructural kev ncaj ncees, thiab ua hauj lwm cia siab rau. Ib qho kev hloov pauv tsis zoo, ib qho kev kho cua sov tsis sib haum, ib qho tsis muaj pov thawj alloy muaj pes tsawg leeg - thiab tag nrho cov kab ke muaj kev pheej hmoo ua rau qaug zog ntxov ntxov, xau, lossis kev puas tsuaj loj hauv kev thauj khoom. Peb tau pom nws tshwm sim: ib tug cobalt-nickel nozzle tawg ntawm 120 bar tom qab 380 lub sij hawm ua hauj lwm vim hais tias cov as-cast grain qauv tsis tau validated tawm tsam AMS 5387 tensile yuav tsum. Tias yog vim li cas precision tsis yog kev lag luam thov. Nws yog qhov kev tswj hwm ib ntus-pib nrog cov khoom siv raw traceability thiab xaus nrog GD & T-raws li kev soj ntsuam zaum kawg.
Vim li cas Casting Ib leeg tsis txaus—Thiab yog vim li cas kev sib koom ua ke tsis sib tham
Feem ntau cov neeg yuav khoom xav tias "foundry hlau casting Hoobkas" txhais tau tias xuab zeb lossis peev casting peev - thiab nres qhov ntawd. Tab sis nyob rau hauv lub ntiaj teb no daim ntawv thov xws li piston twj tso kua mis lub tog raj kheej vaj tse los yog engineering tsheb winch center ncej chais, casting tsuas yog ib kauj ruam. Qhov tseem ceeb geometry nyob rau hauv lub machining: concentricity tolerances ntawm ± 0.015 hli ntawm internal bearing bores, nto tiav hauv qab Ra 0.8 µm ntawm sealing ntsej muag, thiab kub-kho hardness profiles uas yuav tsum muaj sia nyob abrasive slurry flow yam tsis muaj micro-cracking. Ib lub chaw tsim khoom ib leeg tsis tuaj yeem lav qhov no. Tsis tuaj yeem ua lub khw CNC yam tsis muaj kev tswj hwm kev tswj hwm ntawm lub hauv paus casting.
Qhov ntawd yog qhov kev sib koom ua ke ntsug hloov cov txiaj ntsig. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., casting, multi-axis machining, thiab tiav tshwm sim nyob rau hauv ib lub ru tsev ISO-raws li cov cuab yeej sib koom, synchronized thermal kho lub sij hawm, thiab koom ua ke CMM soj ntsuam raws tu qauv. Thaum T800 cobalt-raws li plug yuav tsum muaj ob qho tib si kev taw qhia kev ruaj ntseg tswj * thiab * nruj ID / OD concentricity, tib pab neeg tswj pwm tsim, tom qab nrum kev nyuaj siab nyem, thiab tsib-axis contour milling. Tsis muaj handoffs. Tsis muaj cov ntaub ntawv txhais lus yuam kev. Tsis muaj rework vim mismatched datum references.
Material Mastery Tshaj li Spec Sheet
"Cobalt alloy" ntawm daim duab tsis qhia koj seb nws puas yog L-605, Stellite 6B, lossis AMS 5387 - thiab nws tsis lees paub tias muaj cov carbide dispersion thoob plaws 45-kg casting. Peb niaj hnub sim cov T800 alloy heats uas tuaj yeem siv OES spectroscopy thiab tshawb xyuas microstructure ntawm SEM-EDS ntawm daim coupon hla ntu. Vim li cas? Vim hais tias me me variations nyob rau hauv chromium los yog tungsten cov ntsiab lus ncaj qha cuam tshuam erosion kuj nyob rau hauv cov roj & roj choke li qub. Ib tus neeg siv khoom tau hloov los ntawm cov khoom siv "CoCr alloy" rau AMS 5387-txheej castings-thiab txuas ntxiv kev pabcuam lub neej ntawm 900 mus rau 2,700 teev ua haujlwm hauv cov dej xuab zeb-laden siab.
Qhov no tsis yog theoretical. Nws tau tsim rau hauv lawv cov khoom siv: kev koom tes nrog cov neeg muab ntawv pov thawj, ntau cov ntawv qhia tshwj xeeb zeb xeem tau khaws tseg rau 10+ xyoo, thiab yuav tsum tau tsim ua ntej ua ntej kev sim rau txhua qhov tsis yog qauv geometry. Yog tias koj daim duab hu rau cobalt alloy nozzle nrog 0.3-mm phab ntsa tuab thiab cov cua txias sab hauv, lawv yuav khiav tus tsav tsheb, CT-scan qhov tshwm sim, thiab kho qhov rooj ua ntej cog lus rau tag nrho cov khoom.
Kev Tswjhwm Zoo Hauv Ntiaj Teb—Tsis yog Daim Ntawv Ua Raws Cai
ISO 9001 daim ntawv pov thawj tseem ceeb - tab sis qhov tseem ceeb tshaj yog qhov kev soj ntsuam tshwm sim li cas * ntawm * kev tshuaj xyuas. Ntawm qhov chaw no, txhua qhov hlau lossis stainless hlau casting tau dhau los ua peb qhov yuav tsum tau kuaj xyuas: cov ntaub ntawv pov thawj tuaj (nrog PMI kuaj), kev kuaj xyuas qhov ntev siv Zeiss CMMs calibrated txhua hnub, thiab kev ua haujlwm kawg nkaus - suav nrog kev ntsuas siab txog li 400 bar rau lub cev lub cev thiab kev ntsuas qhov sib npaug rau kev sib hloov twj tso kua mis.
Traceability tsis yog thaj chaw database. Nws yog lub cev: txhua ntu nqa tus lej laser-etched txuas nrog nws cov khoom siv hluav taws xob ntau, hnub casting, machining program version, thiab tus neeg soj ntsuam ID. Thaum ib tug European OEM thov cov hauv paus-ua rau kev soj ntsuam ntawm ib qho kev tawm-ntawm-spec piston vaj tse, pab neeg rub tawm cov txheej txheem tag nrho-suav nrog rau lub cub tawg ntsuas kub los ntawm lub voj voog annealing thiab cov cuab yeej hnav cov nqi them nyiaj los ntawm qhov kawg ntawm kev sib ntsib-hauv 90 feeb.
Qhov no txhais li cas rau koj qhov project tom ntej
Yog tias koj ntsuas a hlau casting Hoobkas rau cov khoom lag luam muaj txiaj ntsig zoo, nug peb nqe lus nug ua ntej thov kev tsocai: Lawv puas tuaj yeem siv tau microstructure * thiab * geometry ntawm tib qhov? Lawv puas muaj cov saw hlau tag nrho-los ntawm kev xaiv cov hlau los ntawm kev ua tiav-lossis cia siab rau cov neeg muag khoom thib peb rau cov kauj ruam tseem ceeb? Thiab thaum ib daim duab qhia GD&T callouts zoo li txoj hauj lwm kam rau ua Ø0.05 hli txheeb ze rau datum A-B-C, lawv puas ua thawj tsab xov xwm tshuaj xyuas * nrog koj cov ntaub ntawv *, tsis yog qhov nominal qhov ntev?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. teb yog—rau tag nrho peb. Lawv lub hom phiaj tseem nyob qis qis: lub siab li qub, lub twj tso kua mis sib dhos, lub tshuab winch, thiab lwm yam khoom siv ua haujlwm uas tsis ua haujlwm tsis yog qhov kev xaiv. Lawv tsis caum qhov ntim. Lawv engineer repeatability. Thiab lawv tsim kev ntseeg siab - tsis yog nrog cov ntawv qhia, tab sis nrog cov ntaub ntawv tshawb xyuas, cov ntaub ntawv pov thawj koj tuaj yeem tshawb xyuas, thiab cov sijhawm xa tuaj tau ntsib ntawm 94.7% ntawm cov xaj nruab nrab hauv 27 lub hlis dhau los.
Rau cov kws tsim khoom uas xav tau cov khoom ua haujlwm uas ua tau - tsis yog tuaj txog - tus khub zoo tsis yog qhov pheej yig tshaj plaws ntawm cov hlau casting Hoobkas. Nws yog ib qho uas ua rau koj qhov tshwj xeeb zoo li daim ntawv cog lus, tsis yog kev tawm tswv yim.
