Thaum engineers qhia 17-4 peev casting rau high-pressure hydraulic li qub los yog turbine twj tso kua mis vaj tse, lawv tsis yog tsuas yog xaiv cov khoom-lawv betting rau seem stability, corrosion kuj, thiab microstructural sib xws nyob rau hauv thermal cycling. Yog vim li cas xaiv txoj cai 174 peev casting Hoobkas tseem ceeb tshaj quoting tus nqi ib leeg. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau pov tseg ntau dua 2,300 qhov tshwj xeeb 17-4 PH cov khoom txij li xyoo 2019-txhua qhov yuav tsum tau nruj GD&T tswj, tag nrho cov kev kho cua sov traceability, thiab xoom kev cuam tshuam ntawm AMS 5643 ua raws.
Vim li cas 17-4 PH Demands Ntau tshaj Standard Investment Casting
17-4 PH stainless hlau tsis yog "tsuas yog lwm yam stainless." Nws tus cwj pwm los nag-tawv tawv txhais tau tias txhua kauj ruam-los ntawm cov qauv geometry mus rau qhov kawg ntawm kev laus lub voj voog-tshwj xeeb cuam tshuam rau lub zog tawm los, qaug zog lub neej, thiab kev ua haujlwm. Peb tau pom cov neeg siv khoom ua tsis tau raws li tus qauv siv vim tias lawv cov neeg siv khoom siv lub plhaub pwm tsim los rau 316, tsis yog qhov thermal expansion ntau dua thiab qeeb zog ntawm 17-4 PH. Qhov tshwm sim? Micro-shrinkage nyob rau hauv nyias-phab ntsa valve lub cev, tawm-ntawm-spec HRC 38-42 tom qab H900 laus, los yog nto tawg thaum lub sij hawm tom qab nrum kev nyuaj siab nyem.
Peb qhov ISO 9001-certified foundry hais txog qhov no nrog peb qhov kev tiv thaiv kev tiv thaiv: Ua ntej, kev cai ceramic plhaub formulations tuned rau 17-4's 1450 ° C ncuav kub. Thib ob, tswj cov cua txias hauv qhov chaw nqus-pab annealing furnaces-tsis muaj ambient-cua quenching. Thib peb, yuav tsum tau ua tom qab cua sov kho CMM validation ntawm cov ntaub ntawv tseem ceeb ua ntej machining pib. Qhov ntawd yog li cas peb tuav ± 0.05 hli ntawm 300 mm diameters yam tsis muaj kev sib tsoo.
Vertical Integration daws cov ntsiab lus mob ntau lawm
Feem ntau cov neeg yuav khoom kho casting thiab CNC raws li cov neeg muag khoom cais. Qhov ntawd ua rau muaj qhov sib txawv ntawm qhov sib txawv: cov txheej txheem tsis sib haum xeeb, cov khoom tsis sib txuas lus, lossis kev tawm tswv yim qeeb ntawm kev hloov ntawm phab ntsa-thickness. Ntawm peb lub chaw Qingdao, tib pab pawg engineering muaj cov saw hlau tag nrho-los ntawm peev pwm tsim los ntawm kev ua tiav kawg.
- Peb tshuab tag nrho 17-4 castings hauv tsev siv 5-axis DMG MORI NTX 1000s, tshem tawm cov neeg muag khoom sib koom ua ke tsis sib haum
- Peb metallurgists co-kos npe kub-kho kab kos nrog raw cov ntaub ntawv pov thawj-txhua batch traces rov qab mus rau ntawv pov thawj SAE AMS 5604 bar Tshuag
- Nto tiav tsis yog qhov kev xav tom qab: Ra 0.8 µm yog tus qauv ntawm lub ntsej muag sealing; Ra 0.4 µm muaj nrog electropolish-tsim los ntawm profileometer, tsis pom kev kwv yees
Qhov kev sib koom ua ke no txo cov sij hawm ua cov hmoov txhuas los ntawm 37% ntawm cov xaj nruab nrab (50-500 pcs) thiab tshem tawm cov kev ua haujlwm rov qab los ntawm cov txheej txheem tsis sib xws. Ib lub twj tso kua mis North American OEM txo qhov kev ua tsis tiav los ntawm 92% tom qab hloov los ntawm ob-tier tus qauv xa mus rau peb qhov kev daws teeb meem 17-4 PH.
Dab tsi cov neeg siv khoom nug tiag tiag ua ntej tso lawv thawj qhov kev txiav txim
"Koj puas tuaj yeem pov cov cua txias hauv qab 2.5 hli txoj kab uas hla?" Yog lawm-peb tau tsim 1.8 hli qhov muag tsis pom qhov nyob hauv 17-4 lub tog raj kheej vaj tsev siv cov txheej txheem poob-core tau lees paub los ntawm kev lag luam CT scan.
"Koj puas txhawb H1150M + ob zaug kev laus rau ultra-siab toughness?" Yog lawm - peb lub tshuab hluav taws xob tau sau cov nqi ramp, lub sij hawm ntub dej, thiab cov cua txias rau ib feem ntau, nrog cov kos npe digital los ntawm QA thiab metallurgy ua.
"Koj qhov kev txiav txim yam tsawg kawg nkaus yog dab tsi rau qhov tsis yog tus qauv geometry?" Tsis muaj MOQ ruaj khov. Peb khiav cov qauv ntawm cov ntoo sib koom ua ke thaum ua tau - thiab faib cov cuab yeej siv pob tshab. Tab sis peb yuav tsis hais yog tias phab ntsa thickness poob qis dua 4.2 hli los yog cov kaum sab xis poob qis dua 1.5 °. Cov kev txwv no tsis yog arbitrary; lawv tau ua raws li 127 ua tsis tiav thawj tsab ntawv tshuaj xyuas nkag rau hauv peb cov ntaub ntawv NCMR sab hauv.
Peb teb cov lus nug no ua ntej - tsis yog hauv kev muag khoom, tab sis hauv peb daim ntawv tshaj tawm kev tshuaj xyuas engineering, xa hauv 72 teev tom qab xa daim duab.
Saib tom ntej: Qhov twg Precision Casting mus tom ntej
Cov pem hauv ntej tom ntej tsis yog qhov loj dua - nws yog kev sib txuas ntse dua. Peb tam sim no embedding micro-features ncaj qha mus rau hauv 17-4 peev castings: laser-etched serial tooj nyeem tau tom qab txhaj tshuaj peening, integrated coolant-txoj kev pov thawj grooves, thiab datum nto pre-machined rau ± 0.015 hli ua ntej CNC kawg. Cov no tshem tawm cov kauj ruam tom qab cam khwb cia thiab txo cov ntsiab lus tshuaj xyuas los ntawm 60%.
Peb R & D tsom xam tseem nqaim thiab sib sib zog nqus: optimizing hybrid txheej txheem qhov twg peev casting muab ze-net duab, thiab precision machining ntxiv qhov chaw ua haujlwm tsuas yog qhov xav tau. Tsis muaj "ib-loj-haum-tag nrho" alloys. Tsis muaj kev kho cua sov los ntawm lub txee. Tsuas yog rov ua tau, sau tseg, tshawb xyuas 17-4 PH kev ua haujlwm - xa los ntawm ib leeg 174 peev casting Hoobkas hauv Qingdao uas kho koj daim ntawv spec zoo li daim ntawv cog lus, tsis yog lus pom zoo.
