Thaum engineers qhia a casting qhov chaw Hoobkas, lawv tsis yog tsuas yog xaj hlau - lawv tab tom twv txiaj kev ntseeg siab ntawm qhov ruaj khov, microstructure sib xws, thiab rov ua haujlwm tau zoo nyob rau hauv siab. Peb tau pom ntau qhov haujlwm nyob rau ntawm qhov qauv qauv vim tias cov neeg koom tes casting tsis tuaj yeem tuav ± 0.05 hli ntawm lub tsev cobalt-alloy twj tso kua mis-los yog phem dua, xa cov khoom nrog zais porosity uas ua tsis tiav hydrostatic kuaj ntawm 350 bar. Tias yog vim li cas cov ntawv thov tseem ceeb hauv cov tshuab hydraulic, cov khoom siv roj & roj, thiab cov khoom siv hluav taws xob hnyav xav tau ntau tshaj li qhov muaj peev xwm nrhiav tau: lawv xav tau kev qhuab qhia metallurgical kev qhuab qhia, cov txheej txheem pob tshab, thiab xoom kam rau ua batch-rau-batch drift.
Qhov twg Casting ntsib Lub Hom Phiaj-Critical Engineering
Tsis yog txhua qhov castings raug tsim sib npaug - thiab tsis yog txhua qhov chaw ua haujlwm casting to taub qhov "lub hom phiaj tseem ceeb" txhais tau li cas. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb kho txhua yam hlau lossis stainless hlau casting raws li kev ua haujlwm ua ntej, cov duab geometric thib ob. Lub piston twj tso kua mis lub tog raj kheej vaj tse tsis yog lub tog raj kheej hollow; Nws yog lub nkoj ntim siab nrog txoj hauv kev ntws sab hauv, qhov chaw sib khi, thiab kev sib txuas txuas-txhua qhov xav tau kev tswj hwm ntawm phab ntsa thickness variation, graphite nodule suav (rau cov hlau ductile), thiab cov kev ntxhov siab seem tom qab kev kho cua sov. Peb tau lees paub qhov no txhua hnub siv cov txheej txheem CMM scans ntawm peb lub xeev thermal: as-casting, tom qab kev ntxhov siab-relief annealing, thiab tom qab machining. Qhov tshwm sim? Tsawg dua 0.8% tus nqi rov ua haujlwm ntawm cov tsev nyob hauv high-complexity - nqis los ntawm kev lag luam-nruab nrab 4.2% nyob rau hauv peb 2022 txoj kev tshawb fawb kev ntsuas sab hauv.
Tsis muaj kev cuam tshuam Alloy tuav - Los ntawm AMS 5387 txog T800
Qee tus neeg muag khoom hais tias "peb nrum cobalt alloys." Tsawg tus ua tau yog lawm. Cobalt-nickel superalloys zoo li AMS 5387 thiab T800 tsis teb rau cov qauv xuab zeb casting tsis. Cov dej kub yuav tsum nyob hauv qhov rais 15 ° C. Pwm preheat profiles sib txawv los ntawm ntu tuab. Thiab shrinkage tsis yog linear-nws yog anisotropic, xav tau cov qauv kev cai raug kuaj xyuas los ntawm kev simulation solidification. Peb khiav txhua txoj hauj lwm cobalt alloy los ntawm MAGMAsoft ua ntej-cam khwb cia, tom qab ntawd kho qhov rooj tsim thiab riser qhov chaw raws li qhov chaw kub qhov chaw. Qhov no yog li cas peb xa cov cobalt alloy nozzles nrog tag nrho-dhau-phab ntsa hardness uniformity (HRC 42-45) thiab xoom centerline microporosity - txawm nyob rau ntawm 120 mm-thick seem. Cov neeg siv khoom qhia peb qhov no tshem tawm ob hom kev ua tsis tiav: kev yaig ntawm qhov chaw nrawm nrawm thiab qaug zog tawg ntawm kev hloov pauv thermal gradient.
Vertical Integration Uas Tau Txais Kev Tswj
Outsourcing casting, machining, thiab ua tiav thoob plaws peb tus neeg muag khoom muaj kev pheej hmoo ntau: kev txhais GD&T misaligned, tsis sib haum ntawm qhov chaw tiav specs, thiab ploj traceability ntawm tshav kub ntau. Peb qhov chaw ua raws ISO ua tau tag nrho peb nyob rau hauv ib lub ru tsev - nrog rau kev qhia metrology raws tu qauv thiab cov khoom sib koom ua ke taug qab. Thaum tus neeg siv khoom xa daim duab kos rau stainless hlau winch center ncej cov menyuam, peb pab neeg tshuaj xyuas nws rau machinability * ua ntej * pwm tsim pib. Peb tus chij nta uas tsis sib haum xeeb nrog cov kev taw qhia kom muaj zog-xws li qhov qhov muag tsis pom qhov sib sib zog nqus mus rau lub axis pouring-thiab nthuav tawm lwm txoj hauv kev uas khaws cia ob qho tib si kev ncaj ncees thiab kev siv nyiaj txiag. Qhov no txiav nruab nrab NPI lub sij hawm voj voog los ntawm 37%, ntawm peb qhov project 2023. Qhov tseem ceeb tshaj, nws txhais tau tias txhua qhov chaw nkoj nrog tag nrho traceability: yaj chemistry, casting ntau ID, kho cua sov nkhaus, CNC toolpath cav, thiab zaum kawg soj ntsuam cov ntaub ntawv - tag nrho cov txuas rau ib tug serial tooj.
Yuav Ua Li Cas Thaum Koj Koom Nrog Tus Neeg Ua Haujlwm Precision Casting
Yog tias koj ntsuas a casting qhov chaw Hoobkas, nug plaub nqe lus nug no—thiab saib seb lawv teb li cas:
- Koj puas tuaj yeem qhia kuv txog peb qhov kawg ntawm AMS 5387 cov ntaub ntawv pov thawj - suav nrog kev tshuaj xyuas spectrographic, cov txiaj ntsig kev ntsuas tensile, thiab daim ntawv pov thawj kuaj hluav taws xob?
- Yuav ua li cas koj txheeb xyuas qhov kev ruaj ntseg ntawm lub voj voog thermal - ua ntej thiab tom qab kev kho cua sov?
- Dab tsi yog koj qhov siab tshaj plaws tso cai sib txawv ntawm qhov tseem ceeb GD&T callouts rau kev nqis peev-cam khwb cia ntau tshaj 50 kg?
- Koj puas khaws cov ntaub ntawv pov thawj raw khoom rau txhua qhov cua sov - thiab txuas lawv mus rau cov lej ua tiav?
Peb tshaj tawm cov lus teb rau lub sijhawm tiag tiag rau tag nrho plaub ntawm peb qhov kev pabcuam portal - tsis yog raws li kev thov kev lag luam, tab sis raws li rub tawm PDFs khi rau cov khoom tsim tawm tiag tiag. Vim tias kev ntseeg tsis yog tsim los ntawm cov ntawv qhia. Nws tau tsim los ntawm cov ntaub ntawv pov thawj, cov txheej txheem rov ua dua, thiab txaus siab tso cai rau cov neeg siv khoom tshawb xyuas qhov tseem ceeb tshaj plaws: cov hlau nws tus kheej.
