Thaum cov engineers qhia cov iav rau hydraulic twj, winch drives, los yog high-pressure valve actuators, lawv tsis tshua muaj pib nrog hmoov metallurgy. Feem ntau ncav cuag thawj forged steel los yog CNC-machined blanks-kom txog rau thaum seem stability, hnav tsis kam, thiab tag nrho cov nqi ib feem pib hloov lub xam. Qhov ntawd yog qhov uas muaj kev mob siab rau hmoov metallurgy iav Hoobkas nres ua lwm txoj hauv kev - thiab dhau los ua qhov kev xaiv tsuas yog xav tau.
Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau pom qhov kev hloov pauv no ua ntej thoob plaws peb lub tebchaws. Lub twj tso kua mis North American OEM txo cov iav hloov zaus los ntawm 40% tom qab hloov los ntawm sintered hlau mus rau AMS 5387 cobalt alloy PM iav hauv lawv lub voj voog piston twj tso kua mis. Ib tus neeg tsim khoom siv tsheb nyob sab Europe txiav lub sijhawm ua haujlwm los ntawm 11 hnub - tsis yog los ntawm kev ua kom nrawm, tab sis los ntawm kev tshem tawm tsib txoj haujlwm thib ob tag nrho. Cov no tsis yog qhov txiaj ntsig theoretical. They came from controlling density gradients within ±0.02 g/cm³, holding pitch diameter tolerance to ±0.015 mm on 16-module spur gears, and achieving surface roughness Ra ≤ 0.8 µm—ua-sintered.
Muaj tseeb precision nyob rau hauv hmoov metallurgy tsis yog hais txog nias hlau hmoov av thiab hu nws ua. Nws pib nrog cov ntaub ntawv pov thawj raw khoom: txhua batch ntawm T800 cobalt-based hmoov nqa tag nrho traceability rau atomization tsis, cov ntsiab lus oxygen (≤120 ppm), thiab particle loj tis (D50 = 18-22 µm). Peb tsis lees txais cov hmoov sab nraum lub qhov rais-txawm tias tus neeg muag khoom muab 15% luv nqi. Vim li cas? Vim tias 0.3% qhov sib txawv ntawm qhov sib txawv ntawm cov iav hauv paus tsim 22% poob rau hauv kev khoov qaug zog lub neej nyob rau hauv kev thauj khoom cyclic. Peb lees paub tias niaj hnub siv Archimedes 'txoj cai thiab micro-CT scanning ntawm cov qauv cores - tsis yog ntawm qhov kawg nkaus xwb, tab sis ntawm ntsuab, xim av, thiab sintered theem.
Peb cov khoom hauv pem teb sib xyaw ua ke peb lub peev xwm tsis sib tham feem ntau PM khw muag khoom noj raws li cov kev pabcuam cais:
- Tswj cua sintering nrog cov dej lwg meej tswj (-40 ° C txog -25 ° C) thiab nitrogen / hydrogen blends - tseem ceeb rau kev tswj cov carbide dispersion hauv cobalt alloys yam tsis muaj decarburization
- Nyob rau hauv tuag coining thov thaum lub sij hawm ejection, tsis raws li ib tug txheej txheem tom qab, xa ± 0.008 hli runout tswj ntawm iav bores yam tsis regrinding
- Kev kho cua sov ua haujlwm Kev sib xyaw ncaj qha tom qab sintering: kev daws annealing ntawm 1180 ° C + ceev quenching rau AMS 5387, ua raws li kev laus ntawm 845 ° C - ua tiav Rockwell C 42-46 thaum khaws cia iav hniav geometry
Qee tus yuav sib cav tias CNC-machined iav muaj qhov zoo tshaj plaws. Muaj tseeb - rau cov geometry yooj yim. Tab sis thaum tus neeg siv khoom nug txog 22-hnub, 3.5-module helical iav nrog 25 ° helix lub kaum sab xis, sab hauv spline, thiab nias-haum bore-machined los ntawm cov khoom T800 bar-cov lej hloov. Cov khoom tawm los poob rau 38%. Lub sij hawm voj voog tshaj 92 feeb. Cov cuab yeej hnav spikes tom qab 17 qhov chaw. Peb cov txheej txheem PM muab tib lub iav hauv ib lub voj voog compacting, nrog rau 91% cov khoom siv, 14-feeb takt lub sij hawm, thiab xoom tooling hnav ntawm batches. Cov iav ua tau raws li AGMA Q12 thiab ISO 1328-1 Chav Kawm 7-tsis muaj kev sib tsoo.
Peb tsis thawb hmoov metallurgy qhov twg nws tsis koom. Yog tias koj daim ntawv thov xav tau iav backlash nruj dua 0.02 hli ntawm kev ua haujlwm kub, lossis yog tias koj qhov kev thauj khoom muaj xws li cov pulses poob siab tshaj 3 × rated torque, peb yuav qhia rau koj ua ntej: forged + tiav-hauv av tseem yog koj txoj hauv kev zoo tshaj. Tab sis rau qhov nruab nrab-ntev khiav (500-10,000 pcs / xyoo), qhov hnyav hnyav (≥200 MPa kev sib cuag kev ntxhov siab), lossis cov tshuab qhov hnyav, suab nrov, lossis cov teeb meem sib dhos nyuaj-PM xa ROI ntsuas. Ib lub chaw tsim khoom siv roj av sab hnub tuaj Asia tau hloov 12-thooj welded iav nqa nrog ib zaug PM sib dhos. Qhov hnyav poob 37%. Kev sib dhos ua haujlwm poob los ntawm 42 feeb mus rau 9. Thiab kev vibration amplitude ntawm 1800 rpm poob 63% - ntsuas ntawm qhov chaw nrog laser Doppler vibrometry.
Dab tsi cais tus muaj peev xwm hmoov metallurgy iav Hoobkas los ntawm lub khw muag khoom xovxwm tsis muaj peev xwm - nws yog qhov kev ntsuas tshwj xeeb tsis ua haujlwm. Thaum tus neeg siv khoom ua tsis tau tiav ntxov hauv lub twj tso kua mis subsea, peb tsis yog hloov nws xwb. Peb hla ntu ntu ua tsis tau tiav, kos cov porosity pawg tiv thaiv kev ntxhov siab contours, correlated oxide inclusions nrog sintering cua cav, thiab redesigned lub tuag kab noj hniav venting qauv. Qhov tshwm sim: xoom teb tsis ua haujlwm dhau 18 lub hlis thiab 47,000 teev ua haujlwm.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm los ntawm Qingdao - tsis yog lub hom phiaj dav dav, tab sis raws li kev sib koom ua ke ntawm kev sib koom ua ke rau cov tshuab uas lub zog tsis yog txav mus xwb. Lawv yog cov muaj zog tiv thaiv cov ntsiab lus. Torque kis tau tus mob anchors. Fatigue-critical interfaces. Peb tsim lawv li ntawd-los ntawm kev xaiv hmoov los ntawm kev ua haujlwm validation. Peb lub chaw tuav ISO 9001: 2015 thiab AS9100D ntawv pov thawj, tab sis qhov tseem ceeb tshaj yog qhov peb siv lawv li cas: txhua lub iav ships nrog tag nrho cov ntawv qhia, cov ntaub ntawv ceev, cov ntaub ntawv hardness hla cov hniav flank thiab hauv paus, thiab metallurgical micrographs ntawm qhov tseem ceeb.
Lub neej yav tom ntej ntawm high-precision iav manufacturing tsis xaiv ntawm PM thiab machining. Nws yog merging lawv ntse-siv PM rau ze-net geometry thiab structural kev ncaj ncees, ces siv tsawg, tsom CNC xov tsuas yog qhov chaw ua hauj lwm xav tau nws. Qhov kev sib xyaw ua ke-casting-machining synergy-yog qhov uas peb R&D tsom mus rau tam sim no. Tsis yog los hloov cov txheej txheem, tab sis tshem tawm kev cuam tshuam.
