Thaum cov kws tshaj lij qhia cov khoom siv cam khwb cia hlau rau cov twj hydraulic lossis engineering tsheb winches, lawv tsis yog xav tau "lub iav." Lawv xav tau kev ruaj ntseg nyob rau hauv 350-bar siab. Microstructure kev ncaj ncees tom qab 10,000 cycles ntawm torsional load. Nto tiav uas tiv taus abrasive slurry yam tsis muaj micro-pitting. Tias yog vim li cas muab los ntawm qhov tseeb cam khwb cia hlau iav qhov chaw Hoobkas-tsis yog ib qho chaw tsim khoom lossis kev cog lus machinist - tsis tuaj yeem sib tham.
Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau machined tshaj 17,000 cam khwb cia hlau iav vaj tse rau piston twj tso kua mis txij li thaum 2019. Peb twb pom dab tsi ua tsis tau tejyam: gears nrog graphite nodule clustering nyob ze cov hniav hauv paus hniav; qhov chaw kub-kho sai heev thiab tawg thaum kawg sib tsoo; castings poured nrog inconsistent txias tus nqi uas warped tom qab CNC contouring. Kev paub tiag tiag-tsis yog phau ntawv qhia-zoo li peb mus txog txhua qhov kev txiav txim.
Peb lub zog pib nrog kev sib koom ua ke ntsug. Feem ntau cov neeg muag khoom outsource casting, machining, lossis xov. Peb tswj tag nrho peb hauv ib qho chaw ua raws ISO hauv Qingdao. Qhov ntawd txhais tau tias tsis muaj kev sib koom tes ntawm cov neeg muag khoom - thiab tsis muaj qhov sib txawv hauv kev taug qab. Thaum tus neeg siv khoom xa GD&T kos duab rau cov khoom siv coj los siv rau hauv cov roj av thiab cov av nkos, peb pab pawg tau lees paub cov khoom siv qib (ASTM A48 Class 30 vs. Class 40), simulates solidification shrinkage nyob rau hauv cov xuab zeb pwm, cov kev pab cuam multi-axis CNC txoj kev los tuav ± 0.015 mm ntawm bore-to-face verifies 20 (20-20) kawg, calibrated Rockwell testers. Txhua kauj ruam txuas rov qab mus rau tib tus lej batch, tib lub cav kho cua sov, tib daim ntawv qhia CMM.
Peb tshwj xeeb hauv cov ntawv thov uas tsis ua haujlwm tsis yog qhov kev xaiv. Xav txog cobalt-alloy twj tso kua mis xws li AMS 5387 lub zog los yog T800-raws li lub hauv paus ncej rollers rau onboard winches. Cov no tsis yog cov khoom ntawm lub txee. Lawv thov kom meej graphite morphology tswj nyob rau hauv lub hauv paus hlau casting, ua raws li nruj-tolerance milling ntawm involute profiles thiab hardened bearing nto. Peb siv ntsuab-xuab zeb casting rau cov qauv rigidity, ces tiav-mill iav hniav ntawm 5-axis tshuab nrog Renishaw probing-tsis muaj phau ntawv sib dhos. Cov neeg siv khoom hauv North America thiab lub teb chaws Yelemees lees paub: peb cov txiaj ntsig thawj zaug ntawm cov khoom no nruab nrab yog 94.7%, tsis yog cov qauv kev lag luam ntawm 72-78%.
Qee tus yuav sib cav hais tias cov chaw tsim khoom hauv tebchaws Meskas lossis EU muab sijhawm ua haujlwm sai dua. Tab sis thaum ib tug European OEM xav tau 42 lub siab valve lub cev nyob rau hauv QT450-10 ductile hlau - nrog rau 12 qhov tseem ceeb bores yuav tsum tau ± 0.01 hli txoj hauj lwm kam rau ua - peb xa nyob rau hauv 28 hnub. Yuav ua li cas? Vim tias peb cov txheej txheem casting-machining hybrid tshem tawm rov kho dua. Peb pov cov duab ze-net nrog cov chaw sib xyaw, tom qab ntawd tshuab txhua qhov chaw ua haujlwm hauv ib qho teeb tsa. Tsis muaj kev ua haujlwm thib ob. Tsis muaj kev sib koom tes txhais lus yuam kev. Tsuas yog rov ua tau qhov tseeb, sau tseg ntawm txhua qhov chaw kuaj xyuas: cov ntaub ntawv xa tuaj, hauv txheej txheem CMM scans txhua 5 daim, kev sim ua haujlwm zaum kawg nrog hydraulic siab cycling mus rau 400 bar.
- Khoom siv traceability: Tag nrho cov ntaub ntawv ntau theem - los ntawm cov hlau tsis zoo ntawm cov hlau yaj mus rau qhov kawg ntawm qhov roughness Ra 0.8 µm ntsuas
- Tsis muaj "standard" cuam tshuam: Peb tshuab tsis yog tus qauv iav piv, helix lub kaum sab xis mus txog 32 °, thiab lub ntsej muag dav tshaj 180 hli yam tsis muaj kev cuam tshuam cov hniav sib cuag.
- Lub ntiaj teb tiag tiag validation: Txhua lub iav vaj tse ships nrog ib daim ntawv ntsuam xyuas kos npe qhia qhov tseeb ntsuas qhov tseem ceeb - tsis yog cov ntawv hla / poob
Yog tias koj ntsuas a cam khwb cia hlau iav qhov chaw Hoobkas, nug peb lo lus nug: Lawv puas tuaj yeem tuav 0.02 hli tag nrho cov cim nyeem ntawm iav dawb runout * tom qab * kev kho cua sov? Lawv puas ua cov qauv metallographic rau txhua qhov 10th casting ntau - lossis tsuas yog thaum kuaj xyuas? Thiab lawv cov engineers puas chij GD&T tsis sib haum * ua ntej * txiav hlau, tsis yog tom qab cov khoom tsim tawm? Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY, cov no tsis yog kev tshawb xyuas theoretical. Lawv yog cov kauj ruam ua haujlwm txhua hnub-ua rau hauv ERP teem sijhawm, kos rau hauv cov neeg ua haujlwm kuaj xyuas, thiab txheeb xyuas los ntawm tus neeg thib peb cov neeg soj ntsuam ob zaug hauv ib xyoos.
Lub neej yav tom ntej belongs rau cov tuam txhab lag luam uas kho cov casting thiab machining raws li kev sib koom ua ke - tsis yog cov kev pabcuam sib txuas. Peb tab tom nthuav dav R & D rau hauv cov txheej txheem hybrid: laser-clad iav hniav ntawm cam khwb cia hlau substrates, ze-net peev casting rau nyias-walled iav nqa, thiab AI-pab qhov rooj tsim los txo qhov porosity nyob rau hauv high-stress aav. Tab sis niaj hnub no tus nqi tseem tsis tau hloov pauv: txhim khu kev qha kev tsim khoom rau cov khoom uas txav cov khoom hnyav, kaw lub siab, thiab ua haujlwm qhov kev pabcuam ncua mus txog 18 lub hlis. Tsis yog vim nws yooj yim - tab sis vim nws yuav tsum yog.
