Cia peb hla lub suab nrov. Thaum cov neeg feem coob hnov 'lub ntiajteb txawj nqus tuag casting qhov chaw', lawv daim duab flawless, high-volume aluminium widgets dov tawm ib kab. Qhov ntawd yog daim ntawv qhia version. Qhov tseeb ntawm hauv pem teb yog kev sib tham tas li ntawm kev tsim qauv, kev coj tus cwj pwm hlau, thiab lub cev tawv nqaij ntawm cov pwm mus tas li. Nws tsis yog tsuas yog nchuav hlau rau hauv cov kab noj hniav hlau xwb; nws yog tswj cov cua sov, cia siab tias yuav shrinkage nyob rau hauv qhov chaw tsis ncaj ncees lawm, thiab paub thaum twg tus tsim yog thov kom muaj ib tug tsis xws luag.
Lub Misunderstood Nruab Nrab
Lub ntiajteb txawj nqus tuag casting zaum nyob rau hauv no nthuav, feem ntau misapplied qhov chaw ntawm xuab zeb casting thiab high-pressure tuag casting. Kuv pom specs tuaj nyob rau hauv txhua lub sij hawm qhov twg ib tug neeg xav tau qhov seem stability thiab zoo tag ntawm ib tug mus tas li pwm, tab sis nrog lub complexity ntawm ib tug xuab zeb casting. Nws tsis ua haujlwm li ntawd. Cov hlau xav tau txoj hauv kev kom ntws thiab pub. Koj tsis tuaj yeem muaj qhov sib cais hnyav tom qab cov phab ntsa nyias - qhov ntawd yog lub qhov khoob khoob tos kom tshwm sim. Cov pwm, ua tsis muaj steel, tsis zam txim.
Peb tau kawm qhov no nyuaj rau xyoo rov qab los ntawm lub bracket rau hydraulic manifold. Cov neeg siv khoom kos duab tau zoo nkauj, compact tsim nrog tuab mounting lug nyob ib sab ntawm nyias flange. Saib zoo heev ntawm CAD. Nyob rau hauv kev muaj tiag, lub lug solidified kawg, nqus hlau los ntawm cov twb-khoom nyias seem, tawm hauv ib tug ntxeem tau, tsis muaj zog junction. Qhov kho tsis yog kho cov ncuav xwb; nws txhais tau hais tias rov qab mus rau tus tsim qauv thiab ntxiv cov kab me me los ua txoj kev pub noj. Qhov ntawd yog hnub-rau-hnub: ib feem engineering.
Qhov no yog qhov chaw foundry qhov kev paub nrog cov txheej txheem sib txawv them tawm. Ib lub tuam txhab zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nrog rau lawv keeb kwm yav dhau hauv plhaub thiab peev casting, yeej muaj ib ceg tuaj ntawm no. Lawv to taub cov qauv solidification los ntawm intricate castings. Siv cov kev paub no rau lub ntiajteb txawj nqus tuag casting txhais tau tias lawv tsis yog cov pwm-fillers xwb; lawv tab tom xav txog yuav ua li cas cov hlau txav thiab txias los ntawm kev mus. Koj tuaj yeem pom lawv txoj hauv kev ntawm lawv lub portal ntawm tsi.com-Nws yog hais txog cov txheej txheem raug rau ib feem, tsis yog muag ib lub peev xwm xwb.
Cov ntaub ntawv tsis yog tom qab
Aluminium tau txais tag nrho cov yeeb yam, tab sis qhov kev ua si hloov tag nrho nrog rau lwm yam alloys. Peb tham gravity tuag casting qhov chaw nyob rau hauv tooj dag, los yog tej yam magnesium alloys. Txhua tus muaj nws tus kheej ua yeeb yam. Aluminium A356? Koj tab tom tswj kev hloov kho strontium rau eutectic silicon thiab cuam tshuam nrog hydrogen pickup. Ncuav turbulently, thiab koj ci hauv porosity ua ntej cov hlau txawm pib txias.
Tab sis hais tias koj xav tau ib feem ntawm cov nickel-raws li alloy rau cov kev pab cuam siab. Tam sim ntawd, lub thermal qaug zog ntawm H13 steel pwm dhau los ua txoj hauv kev tseem ceeb. Lub thermal shock los ntawm pouring ntawm 1500 ° C + piv rau txhuas ntawm 700 ° C yog lim hiam. Pwm lub neej plummets. Koj tus qauv nqi tawm ntawm qhov rais. Qhov no yog qhov uas QSY tau hais txog kev ua haujlwm nrog cov alloys tshwj xeeb xws li npib tsib xee-raws li tsis yog lub mos txwv xwb. Nws txhais tau hais tias lawv yuav tsum tau daws cov teeb meem kev tswj hwm thermal no, yuav yog los ntawm cov txheej txheem pwm tshwj xeeb lossis cov tswv yim tswj cua txias. Nws yog ib pab koomtes sib txawv los ntawm churning tawm aluminium vaj tse.
Kuv nco qab txog qhov project rau lub tsev nyob hauv ob lub stainless hlau. Cov txheej txheem corrosion tau nruj. Cov txheej txheem tuag lub ntiajteb txawj nqus tau muab peb lub ntsej muag tiav thiab sib xws uas xav tau, tab sis tswj hwm qhov sib npaug ntawm ferrite-austenite los ntawm kev tswj kom txias ntawm pwm mus tas li yog npau suav phem. Peb tau mus dhau lub kaum os thermal voj voog profiles ntawm cov pwm ua ntej peb tau txais ib qho microstructure zoo ib yam. Nws yog ib qho tseem ceeb kom nco ntsoov tias 'tuag' hauv lub ntiajteb txawj nqus tuag casting yog ntau npaum li lub thermal tswj cov cuab yeej zoo li lub cuab yeej shaping.
Machining Handshake
Qhov no yog qhov ua-lossis-tawg uas ntau qhov chaw ua si dawb huv fumble. A gravity tuag cast ib feem yog tsis tshua muaj khoom kawg. Nws yog ib qho ze-net-zoo li lub taub hau ncaj nraim rau CNC vise. Yog hais tias lub foundry tsis to taub machining, koj tau txais ob hom mob taub hau: inconsistent datum qhov chaw uas wreck fixturing, los yog muab zais ib qho nyuaj me ntsis los ntawm uneven txias uas shatter cov cuab yeej.
Kev sib koom ua ke yog qhov tseem ceeb. Thaum lub tsev casting kuj tseem khiav CNC kab, zoo li QSY ua, muaj cov lus tawm tswv yim. Tus kws kho tshuab qhia qhov chaw nrhiav pom tias txhua qhov thib peb casting muaj qhov nyuaj ntawm ib qho flange. Lub foundry saib cov pwm txias thiab paub tias ib txoj kab dej yog ib feem ntawm qhov txhaws, tsim kom muaj qhov chaw kub hauv zos thiab hloov kho microstructure. Teeb meem daws tau ntawm qhov chaw. Yog tsis muaj kev sib koom ua ke, nws yog qhov kev ua si liam ntawm tus neeg muag khoom thiab lub khw muag khoom.
Peb hais rau thawj tsab xov xwm tshuaj xyuas uas suav nrog kev sim machining. Npog ib lub pob, rub ib qho qauv, thiab muab tso rau ntawm lub zeb. Nws puas kho kom huv si? Nws puas tshuab kwv yees? Daim ntawv qhia qhov ntev los ntawm CMM yog ib qho, tab sis lub suab ntawm lub tshuab txiav thiab cov xim ntawm cov nti qhia txog zaj dab neeg tiag. Lub ntiajteb txawj nqus zoo tuag casting tsis yog ua tau raws li cov ntawv luam tawm; nws tshuab zoo li ib yam khoom uas yuav twv tau.
Thaum Nws Mus Tsis Zoo (Thiab Nws Yuav)
Kev soj ntsuam tsis tiav yog qhov koj kawm tiag tiag. Kuv tau pom qhov chaw dhau X-ray thiab dye penetrant, ces poob rau hauv kev sim qaug zog. Qhov tawg ib txwm pib ntawm qhov chaw uas zoo li huv. Feem ntau, nws tsis yog qhov tsis xws luag, tab sis hloov maj mam oxide quav lossis micro-shrinkage pawg tsim thaum lub sij hawm sau. Nrog lub ntiajteb txawj nqus pouring, yog hais tias lub rooj vag tsis tsim nyog los tsim laminar ntws, koj quav hauv daim tawv nqaij oxide los ntawm qhov chaw ntawm cov kwj deg. Nws dhau los ua ib qho zoo meej tawg pib faus rau hauv phab ntsa.
Lwm classic yog distortion. Koj rub ib feem ntawm pwm, nws kos tawm ntawm CMM. Tom qab kev kho cua sov (T6 rau txhuas, hais), nws warps. Cov residual stresses los ntawm uneven txias txias nyob rau hauv lub nruj pwm tau tso tawm. Tam sim no koj nyob nraum nyam nrog kev sim ua kom ncaj ib feem uas kho cua sov, uas yog ib txoj hauv kev zoo los qhia cov kev ntxhov siab tshiab. Qhov kev daws teeb meem feem ntau yog nyob rau hauv pwm tsim-symmetrical txias, qee zaum txawm tias cov tswv yim ntawm cov rwb thaiv tsev kom sib npaug ntawm qhov sib npaug ntawm lub hauv ntej.
Cov no tsis yog teeb meem theoretical. Lawv yog cov sij hawm siv ntawm lub shakeout, khawb koj lub taub hau, swapping thermocouples, thiab tweaking pouring basins. Lub hom phiaj yog cov txheej txheem muaj zog, tsis yog ib qho qauv zoo xwb. Tus neeg muag khoom tus nqi tiag tiag yog nyob rau hauv yuav ua li cas lawv daws cov teeb meem uas tsis pom zoo. Puas yog lawv muaj cov txheej txheem metallurgical thiab qhov tob los kuaj xyuas thiab kho, lossis lawv puas tsuas yog pov rau lwm pawg thiab kev cia siab?
