Thaum koj tau nyob ib puag ncig castings thiab machining ntev npaum li peb muaj ntawm Qingdao Qiangsenyuan, koj tsim tau ib qho kev xav rau cov ntaub ntawv. Nws yog nthuav ntau npaum li cas hmoov metallurgy qhov chaw tuaj rau hauv kev sib tham nrog cov neeg siv khoom nrhiav lwm txoj hauv kev. Muaj ib qho kev nkag siab zoo uas PM yog qhov niaj hnub no, cov ntaub ntawv siab-precision pam, uas pheej yig dua thiab muaj txiaj ntsig ntau dua li cov txheej txheem ib txwm muaj xws li peb cov tub ntxhais kawm. plhaub molding los yog peev casting. Qee zaum qhov ntawd muaj tseeb. Tab sis ntau zaus tshaj tsis, qhov tseeb yog messier, thiab kev xaiv tsis yog li ntawd meej-txiav. Nws nyob ntawm daim ntawv thov tsis sib tham: puas yog hais txog kev sib txuas hauv geometries, qhov kawg tensile lub zog nyob rau hauv tshav kub, los yog ntshiab ib feem ntawm tus nqi siab? Kuv tau pom cov haujlwm uas hloov mus rau PM yog qhov kev txav mus los zoo, thiab lwm qhov uas nws tau coj mus rau qhov chaw ntsiag to, raug nqi tsim nyog rov qab mus rau qhov khoom zoo.
Qhov Kev Xaiv Cov Khoom Siv Conundrum
Peb lub khob cij niaj hnub yog hlau xws li cam khwb cia hlau, ntau yam hlau, thiab cov khoom tawv-nickel-based thiab cobalt-based alloys. Cov no yog melted thiab poured. Hmoov metallurgy qhov chaw pib los ntawm lwm qhov chaw: nplua hlau hmoov pressed thiab sintered. Qhov kom zoo dua tam sim no yog ze-net zoo rau qee qhov geometries, tshwj xeeb tshaj yog cov uas muaj ntau theem lossis cov yam ntxwv axial yooj yim. Koj tuaj yeem txo qis machining, uas yog tus nqi txuag nyiaj ntau. Peb muaj ib tus neeg siv khoom ib zaug nrog lub siab-ntim qib tivthaiv, Ameslikas stamped thiab welded los ua ke. Lawv tshawb xyuas PM, thiab rau qhov ntawd, nws zoo tag nrho. Qhov ntom yog txaus, qhov kam rau ua tau tuav, thiab tus nqi ib thooj poob qis heev. Nws ua rau kev nkag siab.
Tab sis ces koj ntaus cov txwv. Thaum qhov kev sib tham tig mus rau qhov kev ntseeg siab ntawm cov qauv, lossis cov khoom uas muaj kev kub ntxhov thiab corrosion-hais tias, nyob rau hauv ib puag ncig turbine los yog kev ua tshuaj lom neeg hnyav-cov lej hloov pauv. Cov ntaub ntawv sintered, txawm tias tom qab forging (P / M forging), tuaj yeem tawm tsam kom haum rau homogenous, tsis muaj qhov tsis xws luag ntawm microstructure zoo tsim peev casting, tshwj xeeb tshaj yog nyob rau hauv peb cov alloys tshwj xeeb. Muaj ib txwm porosity xav txog. Nws tsis tas yuav muaj qhov tsis zoo; nws yog nyob rau hauv. Tab sis yog tias koj txoj haujlwm tsis tuaj yeem muaj peev xwm rau kev sib cuam tshuam porosity nyob rau hauv siab, koj tam sim ntawd tig rov qab mus rau txheej txheem hlau molten.
Kuv nco qab txog qhov kev txheeb xyuas qhov ua tsis tiav uas peb tau hais kom sab laj rau. Lub sintered stainless hlau valve lub rooj yog underperforming nyob rau hauv ib tug corrosive, high-cycle fatigue daim ntawv thov. Qhov teeb meem taug qab rov qab mus rau qhov tsis sib xws ntawm qhov sib txawv ntawm qhov tshwj xeeb, qhov kev sib tw PM classic, ua rau txoj kev nyiam corrosion thiab pib tawg. Qhov kev daws teeb meem, tom qab ntau rov qab los, tsis yog hloov kho PM txheej txheem ntxiv tab sis hloov mus rau qhov tseeb-cam khwb cia CF8M stainless ntawm peev casting. Tus nqi ib feem tau nce, tab sis tus nqi lifecycle poob qis. Qhov ntawd yog hom kev qhia uas koj tsis nco qab.
Qhov twg Casting thiab PM Diverge (thiab Qee zaus ntsib)
Qhov no tsis yog hais txog kev tshaj tawm ib qho thev naus laus zis zoo tshaj. Nws yog hais txog haum. Ntawm QSY, nrog peb lub xyoo caum hauv plhaub molding thiab peev casting, peb pom peb lub niche kom meej. Rau qhov nyuaj heev, nyias-walled geometries nyob rau hauv cov kab txawv alloys, casting yog feem ntau unbeatable. Xav txog lub impeller nrog twisted, aerofoil-puab hniav. Sim nias uas los ntawm hmoov yog npau suav phem; casting nws yog ib qho kev nkag siab zoo, yog tias muag heev, kos duab. Qhov saum npoo tiav los ntawm lub plhaub zoo ceramic kuj feem ntau yog qhov zoo tshaj plaws rau qhov zoo li-sintered, uas feem ntau xav tau kev ua haujlwm thib ob.
Txawm li cas los xij, kom tshem PM yuav ruam. Rau qhov yooj yim, symmetric duab zoo li lub zog, bushings, los yog tej yam automotive connectors, PM feem ntau yog tus yeej kev lag luam. Kev siv cov khoom siv yog qhov zoo heev - me me kom tsis muaj khib nyiab. Qhov peb tau kawm yog tias cov kauj ruam tom qab sintering yog qhov twg lub ntiaj teb tuaj yeem sib tsoo. Qhov ntawd yog qhov peb CNC machining kev txawj ntse los ua si. Ntau hmoov metallurgy qhov chaw xav tau precision machining ntawm cov yam ntxwv tseem ceeb tom qab sintering. Peb tau machined countless sintered qhov chaw - ntxiv threads, honing bores, tsim precision flats. Lub machining tsis txawv; koj tab tom txiav cov khoom ntxeem tau, yog li cov cuab yeej lub neej thiab cov nqi pub yuav tsum tau hloov kho. Nws yog ib qho kev xav txawv ntawm lub khw hauv pem teb.
Kuj tseem muaj qhov chaw hybrid: Hlau Txhaj Moulding (MIM), uas zoo li PM tus kwv tij txheeb ze. Nws tso cai rau cov duab ntau dua li cov pa nias. Peb tau muab machined castings tom qab hloov los ntawm MIM qhov chaw rau daim ntawv thov khoom siv kho mob, qhov ntim tau tsim nyog rau tus nqi siab thiab kev txi me ntsis hauv qhov kawg ntawm lub zog tau txais. Qhov tseem ceeb yog qhib kev sib txuas lus txog kev lag luam tawm los ntawm thawj theem pib.
Qhov Tseeb Ntawm Kev Ua Siab ntev thiab ntim
Lub ntsiab lus tseem ceeb ntawm kev tsis meej pem yog kam rau ua. Cov ntawv muag khoom tuaj yeem sau cov lej zoo rau PM. Tab sis cov no feem ntau yog rau ib qho, optimized dimension ntawm kev tswj ntau lawm. Nyob rau hauv lub ntiaj teb no ntau lawm thoob ib batch, qhov sib txawv yuav ua tau siab tshaj nyob rau hauv machining los ntawm ib tug khoom casting dawb paug. Vim li cas? Dimensional hloov thaum lub sij hawm sintering tsis zoo tag nrho; nws tau cuam tshuam los ntawm hmoov ntau, qhov cub kub kub gradients, thiab ib feem tso. Rau ib feem uas yuav tsum tau muaj ib tug +/- 0.025mm kam rau ua rau ib qho tseem ceeb bore, pib nrog ib tug sintered nyob ze-net duab yuav tsis txuag nyiaj yog tias koj yuav tsum tshuab 90% ntawm qhov chaw twg los xij mus ntaus cov spec ntseeg tau. Hauv cov xwm txheej zoo li no, qee zaum nws yooj yim dua los pib nrog lub tshuab ua haujlwm casting dawb paug.
Volume yog lwm tus dictator. Cov cuab yeej nyuaj rau kev kub siab PM nias yog kim. Rau kev khiav ntawm 50,000 daim ib xyoos, nws yooj yim tsim nyog. Rau 500 daim? Yuav luag tsis tau. Peb cov txheej txheem casting, tshwj xeeb tshaj yog lub plhaub molding, tuaj yeem hloov tau yooj yim ntawm qis mus rau nruab nrab ntim. Cov qauv khoom siv yog pheej yig dua thiab yooj yim rau kev hloov kho. Qhov kev hloov pauv no yog ib yam peb ntawm Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) muaj nuj nqis heev, raws li nws cia peb ua hauj lwm zoo nrog ob qho tib si loj batch thiab kev loj hlob-theem tej yaam num.
Kuv tau zaum los ntawm kev tshuaj xyuas tsim qhov twg ib tug tub ntxhais hluas engineers hais rau PM vim tias phau ntawv hais tias nws ua haujlwm tau zoo. Tab sis thaum peb rhuav tshem tag nrho cov nqi - cuab yeej, sintering, qhov tsim nyog thib ob machining, thiab kev pheej hmoo ntawm seem - tiv thaiv tus nqi ntawm lub tshuab ua haujlwm tsawg, cov lej feem ntau tig, tshwj xeeb tshaj yog rau cov qib alloy peb feem ntau lis. Lub ntsiab lus sib cais yog siab dua li ntau qhov kev xav.
Cov lus qhia los ntawm Lub Khw Muag Khoom
Cov pov thawj yeej ib txwm nyob rau hauv lub machining. Koj tuaj yeem qhia ntau yam txog ib feem ntawm lub hauv paus chiv keeb los ntawm seb nws coj li cas ntawm CNC zeb lossis tshuab dhos. Ib feem cam khwb cia, yog hais tias tus txheej txheem yog suab, cov cav tov nrog ib tug kwv yees sib xws. Cov chips tawg kom huv si. A hmoov metallurgy ib feem muaj qhov sib txawv. Cov khoom siv cuam tshuam tuaj yeem ua rau kev txiav me ntsis gritty, thiab cov cuab yeej hnav cov qauv sib txawv. Coolant nkag mus rau hauv porosity kuj yog ib qho teeb meem, qee zaum ua rau muaj kab mob los yog tom qab seepage. Peb tau kawm qhov no nyuaj heev thaum ntxov, machining ib pawg ntawm sintered bronze bearings. Coolant tau daig hauv qhov hws thiab tom qab ntawd leached tawm, ua rau corrosion nyob rau hauv lub rooj sib txoos. Tam sim no, rau qhov tseem ceeb PM Cheebtsam, peb feem ntau teev cov resin impregnation los yog sealing kev kho mob ua ntej zaum kawg machining, uas ntxiv ib kauj ruam thiab nqi.
Qhov kev sib koom tes ntawm kev tawm tswv yim no yog qhov tseem ceeb. Peb pab pawg machining muab cov tswv yim ncaj qha rau peb cov neeg ua haujlwm casting thiab lwm tus PM. Lawv yuav hais tias, Cov phab ntsa no ntawm qhov sintered yog qhov tsis yooj yim heev rau lub clamping quab yuam uas yuav tsum tau siv lub tshuab rau sab nraud, los yog qhov zoo li-cam khwb cia saum npoo ntawm no yog qhov zoo tshaj plaws rau kev ua tiav nrog lub teeb ci. Qhov kev ua tau zoo, kev paub hauv av no ua rau peb cov lus pom zoo rau cov neeg siv khoom ntau dua li cov txheej txheem xaiv cov txheej txheem ib txwm muaj.
Xaus Tsis Muaj Kev Txiav Txim Siab
Yog li, qhov twg yog qhov no cia peb nrog hmoov metallurgy qhov chaw? Lawv yog cov cuab yeej muaj zog hauv lub thawv tsim khoom, tab sis tsis yog universal wrench. Rau peb, kev khiav hauj lwm ntawm kev sib tshuam ntawm casting thiab precision machining, lawv sawv cev rau txoj kev uas peb hwm thiab feem ntau koom tes nrog. Qhov kev tshwm sim zoo tshaj plaws tshwm sim thaum kev xaiv ntawm PM thiab casting raug kho raws li kev txiav txim siab loj thiab kev lag luam, tsis yog qhov kev txiav txim siab yav dhau los raws li qhov sib txawv.
Nws los mus nug cov lus nug uas yog ua ntej: Dab tsi yog qhov tseem ceeb-rau-zoo cwj pwm? Dab tsi yog qhov ntim txhua xyoo, suav nrog lub neej voj voog? Tus nqi tag nrho ntawm kev ua tswv yog dab tsi, tsis yog tus nqi daim? Thiab thaum kawg, koj puas muaj ib tus neeg muag khoom uas nkag siab txog qhov muaj zog thiab qhov tsis muaj zog ntawm ob lub ntiaj teb, thiab tsis yog kev ncaj ncees rau ib leeg vim nws yog txhua yam lawv ua?
Qhov ntawd yog qhov kev xav uas peb tau tsim dua 30 xyoo. Txawm hais tias nws xa ib qho nyuaj, high-alloy peev casting rau lub twj tso kua mis los yog machining lub siab-ntim sintered iav rau ib daim iav tiav, lub hauv paus ntsiab lus yog tib yam: phim lub manufacturing kev muaj tiag rau ib feem ntawm lub destiny nyob rau hauv lub teb. Txhua yam tsuas yog suab nrov xwb.
