Thaum cov neeg feem coob hnov 'grey cam khwb cia hlau mechanical qhov chaw', lawv pom tej yam hnyav, pheej yig, thiab yooj yim. Qhov ntawd yog thawj qhov yuam kev. Qhov kev muaj tiag yog ntau nuanced, thiab tau txais nws tsis ncaj ncees lawm ntawm lub khw hauv pem teb raug nqi nyiaj tiag thiab sijhawm.
Tus Neeg Ua Haujlwm Tsis Txaus Siab
Cia peb paub meej: grey hlau tsis raug xaiv rau nws lub zog tensile. Koj siv nws rau nws lub peev xwm damping thiab hnav tsis kam. Kuv tau pom ntau tus qauv tsim qhov twg ib tus neeg qhia txog cov hlau tsis zoo lossis txawm tias cov hlau rau lub tsev lossis lub hauv paus, caum tus lej muaj zog dua ntawm daim ntawv spec, tsuas yog kom muaj tag nrho cov kev sib dhos vibrate zoo li lub diav rawg lossis hnav ua ntej ntawm zawv zawg cov ntsiab lus. Cov graphite flakes hauv grey hlau yog nws cov riam phom zais cia. Lawv ua zoo li built-in vibration dampers thiab muab cov nyhuv lubricating. Nws yog ib yam khoom uas zoo tshaj nyob rau hauv compression, tsis nro. Yog tias koj qhov feem ntau pom cov loads compressive thiab xav tau nyob ntsiag to thiab ruaj khov, grey hlau feem ntau yog qhov ntse dua, kev xaiv nyiaj txiag ntau dua.
Qhov no yog qhov uas kev paub nrog lub hauv paus txheej txheem ua qhov tseem ceeb. Cov cua txias thaum lub sij hawm solidification ncaj qha tswj cov graphite flake loj thiab tis, uas nyob rau hauv lem dictates lub kawg khoom. Ib feem nrog ib ntu tuab thiab nyias ntu txias txias tib yam yuav muaj qhov sib txawv microstructures. Kuv nco qab ib pawg ntawm cov cuab yeej siv lub hauv paus peb tau txais ntau xyoo dhau los uas tsim qhov tsis sib haum xeeb ntawm cov kev taw qhia mounting qhov chaw. Qhov teeb meem tsis yog cov khoom siv qib; nws yog qhov kev tso kawm ntawm cov risers thiab qhov kub thiab txias, uas ua rau chilling hauv qee qhov chaw thiab softer graphite hauv lwm tus. Daim duab tsuas yog hais tias Chav Kawm 30 Grey Hlau, tab sis qhov ntawd tsis txaus. Peb yuav tsum tau ua hauj lwm nrog lub foundry ntawm tus qauv tsim thiab rooj vag system.
Cov tuam txhab uas tau nyob hauv qhov kev ua si casting tau ntau xyoo lawm, zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), to taub qhov no intrinsically. Nrog ntau tshaj 30 xyoo nyob rau hauv casting thiab machining, lawv tau pom cov pitfalls. Thaum koj xauj lawv cov ntaub ntawv ntawm tsi.com, koj tsis tsuas yog saib cov khoom tiav; koj tab tom saib txoj kev nkag siab tob. Rau grey cam khwb cia hlau mechanical qhov chaw, qhov no txhais tau hais tias paub yuav ua li cas los tsim pwm thiab tswj cov txheej txheem kom tau txais cov qauv zoo nyob rau hauv qhov chaw zoo, tshwj xeeb tshaj yog rau cov duab nyuaj.
Machining: Qhov twg qhov kev sib tw tiag tiag feem ntau dag
Casting tsuas yog ib nrab ntawm zaj dab neeg. Lub machining ntawm grey hlau qhov chaw yog nws tus kheej tshwj xeeb khoom siv tes ua. Cov plua plav tsis zoo - cov graphite zoo thiab cov khoom hlau - yog abrasive thiab tau txais txhua qhov chaw. Nws ua rau muaj kev puas tsuaj rau cov lus qhia ntawm lub tshuab thiab cov pob ntsia hlau yog tias tsis tau tswj xyuas nruj nrog kev pom zoo thiab kev sib khi. Koj tsis tuaj yeem siv tib lub tswv yim coolant ib yam li cov hlau; cov nplua tuaj yeem txhaws cov tshuab. Peb kawm qhov no txoj kev nyuaj ntawm kev ua haujlwm siab ntim tshuab twj tso kua mis. Peb cov txheej txheem dej-soluble coolant tau hloov mus rau hauv cov slurry uas rhuav tshem cov twj tso kua mis hauv ib lub lis piam. We switched to a more viscous, filtering-specific coolant and ramped up maintenance cycles.
Tom qab ntawd muaj cov cuab yeej. Carbide inserts nrog ntse, zoo geometries ua hauj lwm zoo, tab sis lub cuab tam lub neej yuav unpredictable yog hais tias koj ntaus ib tug xuab zeb los yog ib tug nyuaj qhov chaw los ntawm ceev ceev txias. PCD (polycrystalline pob zeb diamond) cov cuab yeej yog qhov zoo heev rau kev ua tiav ntawm cov hlau huv, zoo ib yam, muab lub neej zoo kawg, tab sis tus nqi nce siab. Nws yog xam: ib feem ntim, yuav tsum tau nto tiav, thiab kam rau ua. Rau qhov kev tho txawv siab ntawm lub cev lub rooj zaum, peb tau tsiv mus rau PCD thiab tsis txhob saib rov qab - qhov sib xws tau them rau nws tus kheej.
Qhov no yog vim li cas ib tug neeg muab khoom uas integrates casting thiab CNC machining nyob rau hauv ib lub ru tsev, raws li QSY ua, muaj qhov zoo sib xws. Lawv tuaj yeem npaj cov txheej txheem casting nrog cov machining hauv siab. Lawv tuaj yeem ntxiv me ntsis ntxiv cov khoom lag luam hauv thaj chaw uas muaj qhov ua rau shrinkage, los yog tso ib txoj kab sib faib kom txo cov machining ntawm qhov chaw tseem ceeb. Qhov Kev Tsim Nyog Rau Kev Tsim Nyog Kev xav no tshem tawm ntau qhov mob taub hau uas tshwm sim thaum casting thiab machining yog ua los ntawm cov neeg muag khoom sib cais, txiav tawm.
Cov Lus Nug Alloying thiab Kev Kho Nto
Plain grey hlau (xws li ASTM Class 20, 30, 35) npog 80% ntawm daim ntawv thov. Tab sis qee zaum koj xav tau me ntsis ntxiv. Ntxiv chromium nce hardness thiab hnav tsis kam rau qhov chaw xws li nres nruas lossis lub tog raj kheej liner, tab sis nws kuj ua rau cov hlau nkig thiab nyuaj rau lub tshuab. Nickel ntxiv pab ua kom cov graphite zoo dua qub thiab txhim kho kev sib haum xeeb thiab lub zog, feem ntau siv rau hauv cov ntu tuab kom tiv thaiv softening. Nws yog ib qho kev sib npaug.
Thiab koj yuav luag tsis tau siv raw, raws li-machined grey hlau nto nyob rau hauv daim ntawv thov dynamic. Nws xav tau kev tiv thaiv lossis kev txhim kho. Phosphating yog feem ntau rau corrosion kuj thiab raws li xim puag. Rau zawv zawg qhov chaw xws li piston rings lossis compressor daim hlau, tin plating lossis induction hardening yuav raug teev tseg. Kuv nco ntsoov ib qhov project rau hydraulic manifold blocks qhov twg peb hla kev kho deg kom txuag tau nqi. yuam kev loj. Me nto xeb tsim thaum lub sij hawm xa khoom txawv teb chaws, uas tom qab ntawd paug tag nrho cov hydraulic system thaum pib. Tus nqi ntawm qhov tsis ua hauj lwm dwarfed tus nqi ntawm ib qho yooj yim phosphating kauj ruam.
Thaum Nws Ua Tsis Taus (Thiab Vim Li Cas)
Grey hlau qhia rau koj thaum nws tsis zoo siab. Nws qhov ua tsis tiav feem ntau yog nkig thiab pom tseeb. Classic grey hlau suab - ib tug dull thud es tsis txhob ntawm lub nplhaib thaum ntaus - yog ib tug ceev teb daim ntawv ntsuam xyuas. Feem ntau cov kev ua tsis tiav kuv tau tshawb xyuas los ntawm peb yam: siv lub tensile lossis shock load nws yeej tsis tau txhais hais tias yuav ua li cas (xws li siv ib tug grey hlau bracket raws li ib tug lever), thermal shock (ceev ceev, tsis sib xws cua sov thiab txias ua rau tawg), los yog corrosion los ntawm ib tug tsis haum ib puag ncig.
Ib rooj plaub tshwj xeeb cuam tshuam nrog loj, kev cai gearbox vaj tse. Nws dhau tag nrho cov kev ntsuas siab tab sis ua tsis tiav hauv kev pabcuam tom qab rau lub hlis nrog kev puas tsuaj loj. Metallurgical tsom xam pom cov kab nrib pleb los ntawm ib tug subsurface shrinkage kab noj hniav nyob ze ntawm ib tug ntse sab hauv ces kaum - ib tug kev nyuaj siab riser. Lub casting nws tus kheej tau raws li qib spec, tab sis tus tsim (lub kaum ntse ntse) ua ke nrog ib tug me me, tso cai rau casting imperfection tsim qhov tsis ua hauj lwm point. Kev kho yog qhov hloov pauv yooj yim tab sis tseem ceeb heev: ntxiv ib lub vojvoog fillet rau lub ces kaum ntawm tus qauv, uas lub foundry, QSY, tuaj yeem yooj yim haum. Nws tseem ceeb tias kev qhia cov khoom tsis txaus; koj yuav tsum tsim rau cov txheej txheem casting.
Lub Niche rau Plhaub thiab Peev Casting hauv Hlau
Feem ntau grey hlau qhov chaw yog xuab zeb cam khwb cia. Tab sis rau qhov chaw uas yuav tsum tau ua kom zoo dua saum npoo, nruj dua li-casting kam rau ua, los yog ntau dua, thinner geometry, lwm cov txheej txheem tuaj rau hauv kev ua si.
