Thaum engineers qhia a kev cai peev casting Hoobkas, lawv tsis yog tsuas yog xaj cov khoom-lawv tau cog lus rau qhov kev ruaj ntseg ntawm qhov chaw, microstructural kev ncaj ncees, thiab kev ntseeg siab ua haujlwm nyob rau hauv cov xwm txheej hnyav. Peb tau pom ntau txoj haujlwm qeeb los ntawm qhov tsis sib xws ntawm cov khoom tsim muaj peev xwm: lub twj tso kua mis vaj tsev cam khwb cia nrog porosity ze ntawm qhov chaw sib khi; cobalt alloy nozzle machined nrog subsurface microcracks tom qab kev kho cua sov; lub winch center ncej cov menyuam uas dhau CMM tshuaj xyuas tab sis ua tsis tiav kev sim qaug zog ntawm 42% ntawm lub neej tsim. Cov no tsis yog cov xwm txheej zoo-lawv yog cov tsos mob ntawm cov khoom siv sib cais thiab cov neeg muag khoom siv hluav taws xob tsis muaj cov txheej txheem tshwj xeeb.
Vim li cas Cov Khoom Siv Tshwj Xeeb Casting Paub-Yuav Ua Li Cas Beats "Ib-Size-Fits-Txhua" Foundries
Kev nqis peev casting tsis yog tsuas yog nchuav hlau molten rau hauv cov plhaub ceramic. Nws yog hais txog kev tswj cov kev sib tw solidification hauv AMS 5387 cobalt alloy - qhov twg txawm tias 0.3 ° C / min txias tus nqi sib txawv hloov pauv dendrite caj npab sib nrug thiab cuam tshuam kev yaig tsis kam nyob rau hauv txoj kev ua kua dej siab. Nws yog hais txog kev tswj cov thermal expansion tsis sib haum xeeb ntawm T800-raws li cores thiab stainless hlau plhaub thaum lub sij hawm dewaxing, tiv thaiv microfissures pom tsis tau rau X-ray tab sis kev puas tsuaj nyob rau hauv cyclic siab. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., txhua qhov cobalt-nickel ncuav pib nrog pre-rhuab pwm tuav ntawm 1,120 ° C ± 5 ° C - tsis yog ntau yam, tab sis ib lub hom phiaj txheeb xyuas nrog dual-point infrared pyrometers ua ntej txhua pawg. Peb tsis kho AMS 5387 li "tsuas yog lwm superalloy." Peb kho nws raws li cov khoom siv uas xav tau kev cog lus crucibles, oxygen-scavenged argon purging, thiab tom qab cam khwb cia tshuaj annealing nyob rau hauv lub tshuab nqus tsev vacuum furnaces nrog ± 2 ° C uniformity. Tias yog vim li cas peb cov cobalt alloy nozzles niaj hnub ua tiav Ra ≤ 0.8 µm as-cam khwb cia ntawm qhov chaw ntws tseem ceeb - tshem tawm 60% ntawm lub sijhawm ua haujlwm thib ob thaum khaws cov qauv nplej.
Vertical Integration Tsis yog Buzzword-Nws yog Koj Qhov Kev Pov Hwm Dimensional
Qee cov neeg muag khoom outsource machining rau peb tog CNC khw. Lwm cov subcontract kub kho. Qhov ntawd tsim peb lub ntsiab lus tsis ua haujlwm: thermal distortion los ntawm kev tswj tsis tau quench tus nqi, kev sib koom ua ke misalignment ntawm casting datum thiab machining fixture, thiab deg paug thaum thauj. QINGDAO QIANGSENYUAN's ISO-raws li qhov chaw ua haujlwm ua haujlwm casting, multi-axis machining, thiab ua tiav hauv ib lub ru tsev-nrog GD&T databases sib koom, synchronized metrology calibration cov sij hawm, thiab kev sib koom ua ke traceability cav. Thaum ib tus neeg siv khoom xa tuaj rau peb lub piston twj tso kua mis lub tog raj kheej lub tsev teeb duab nrog ± 0.015 hli txoj hauj lwm kam rau ntawm yim lub qhov rooj, peb tau teeb tsa qhov kev pheej hmoo: cov qauv xuab zeb tsis tuaj yeem tuav qhov spec hla 300 hli ntev. Peb cov lus teb tsis yog "peb tsis tuaj yeem ua tau" - nws yog "cia peb hloov mus rau kev nqis peev casting nrog ceramic core sib dhos, tom qab ntawd ua tiav-dhau tag nrho cov chaw nres nkoj hauv ib qho clamping siv peb 5-axis DMG Mori nrog Renishaw PH10M sojntsuam." Qhov tshwm sim: thawj-kab lus dhau ntawm tag nrho 12 qhov tseem ceeb. Tsis muaj rework. Tsis muaj daim ntawv teev sijhawm.
Kev Tswjhwm Zoo Hauv Ntiaj Teb—Tsis yog Daim Ntawv Ua Raws Cai
"ISO certified" txhais tau hais tias me ntsis yog tias cov neeg soj ntsuam xyuas tsuas yog qhov ntev kawg nkaus thiab hla microstructure validation. Peb txheeb xyuas cov khoom siv cobalt-nickel billets nrog OES spectroscopy thiab kuaj ultrasonic rau sab hauv discontinuities-ua ntej melting. Thaum lub sij hawm casting, thermocouples embedded nyob rau hauv lub plhaub phab ntsa log real-time kub profiles, tsis tsuas yog rauv taws teeb setpoints. Tom qab kev ua haujlwm, txhua lub siab valve tau kuaj xyuas helium ntawm 1.5 × kev ua haujlwm siab, tsis yog zas xim nkaus xwb. Thiab yog - peb khaws tag nrho cov ntaub ntawv traceability: ntau tus lej, cov ntaub ntawv txheeb xyuas yaj, kev kho cua sov nkhaus, CMM tshuaj xyuas daim ntawv qhia, thiab daim ntawv qhia qhov roughness yog txuas rau hauv peb qhov system ERP thiab xa nrog txhua qhov khoom xa tuaj. Ib tug North American hydraulic OEM hais rau peb: "Koj pob ntawv traceability txiav peb cov kev tshuaj xyuas hauv QA los ntawm 14 hnub mus rau 36 teev." Qhov ntawd tsis yog kev ua haujlwm-uas yog kev ntseeg siab.
Xaiv Koj Lub Tuam Txhab Kev Lag Luam Kev Lag Luam Casting - Dab tsi Tiag Tiag Tiag
- Nug rau cov ntaub ntawv txheej txheem tshwj xeeb alloy: Tsis yog "peb nrum cobalt alloys," tab sis "qhia peb koj qhov kawg peb AMS 5387 pours-xws li pwm preheat cav, ncuav kub, thiab post-cast microhardness maps."
- Xav tau cov ntaub ntawv pov thawj hauv txheej txheem metrology: Xav tau cov duab ntawm CMM fixtures siv ntawm koj qhov geometry - tsis yog cov screenshots dav dav los ntawm phau ntawv qhia kev cob qhia.
- Ntsuam xyuas lawv cov kev koom tes engineering: Xa daim duab GD&T hnyav nrog cov ntaub ntawv tsis meej. Tus khub tiag tiag yuav teb tsis pub dhau 48 teev nrog cov lus nug tshwj xeeb - tsis yog tus qauv "peb yuav rov qab rau koj."
- Txheeb xyuas qhov ntsuas ntsug: Yog tias lawv thov "tag nrho cov kev hloov pauv," lees paub seb puas kho cua sov, kuaj tsis muaj kev puas tsuaj, thiab kev ua tiav tiav ntawm qhov chaw - lossis xav tau xa mus rau cov neeg ua haujlwm tsis tau lees paub.
A kev cai peev casting Hoobkas khwv tau nws lub npe tsis yog los ntawm lub peev xwm, tab sis los ntawm qhov tob npaum li cas nws embeds metallurgical kev qhuab qhia rau hauv txhua qhov kev ua haujlwm - los ntawm cov ntaub ntawv raw khoom mus rau qhov kawg ntim. QINGDAO QIANGSENYUAN TECHNOLOGY tsis caum ntim. Nws daws teeb meem qhov twg tus qauv foundries nres: cobalt alloy plugs rau subsea tswj li qub, tsis yog-tus qauv twj tso kua mis foundations resisting 22,000 psi pulsation, winch center ncej chais ciaj sia taus 10⁷ cycles nyob rau hauv abrasive suab puam ib puag ncig. Lub sijhawm tom ntej koj tus qauv tsim thawb cov khoom lossis kev txwv tsis pub dhau, nug tsis yog "leej twg tuaj yeem pov qhov no?" tab sis "Leej twg twb tau nrum ib yam nyuaj dua-thiab ua pov thawj tias nws ua haujlwm?"
