Yog tias koj xav tias lub ntiajteb txawj nqus molding tsuas yog hais txog kev cia lub ntiajteb txawj nqus ua haujlwm, koj ploj lawm cov khoom siv tes ua. Nws yog qhov kev tswj hwm maj mam, qhov yuav luag imperceptible qaij ntawm lub ladle, qhov kub thiab txias gradient koj hnov ntawm koj sab plhu ze ntawm pwm - qhov ntawd yog qhov txheej txheem tiag tiag nyob. Ntau cov nplooj ntawv specs thiab cov lus ceev ceev kho nws raws li qhov yooj yim, kev xaiv qis-tech, tab sis qhov ntawd yog qhov tsis raug nqi kim. Qhov sib txawv ntawm lub suab nrov thiab cov khoom seem feem ntau hinges ntawm cov ntsiab lus tsis muaj CAD cov ntaub ntawv qhia.
Lub misunderstood Physics ntawm ib qho yooj yim ncuav
Cia peb tau tshwj xeeb. Lub sij hawm gravity pwm casting implies ib tug passive quab yuam, tab sis nyob rau hauv kev xyaum, koj nquag tswj lub caij nplooj zeeg tswj. Cov hlau tsis yog poob xwb; nws ntws. turbulent heev, thiab koj tau txais huab cua nkag thiab oxide zaj duab xis - qhov tsis xws luag uas yuav tsis tshwm sim kom txog rau thaum machining, uas yog ib txoj kev phem heev kom paub tias koj nkim ib lub lim tiam. Kuv kawm qhov no thaum ntxov nrog ib pawg ntawm cov twj tso kua mis. Lub geometry muaj ib ntu nyias pub rau hauv ib lub hub tuab. Peb ncuav ncaj rau hauv, phau ntawv style. Qhov tshwm sim? Shrinkage porosity txoj cai ntawm kev sib tshuam. Lub ntiajteb txawj nqus pub tsis txaus; peb xav tau cov pwm nws tus kheej los pab ncaj qha rau solidification.
Qhov ntawd yog qhov uas cov pwm tsim - qhov rooj vag thiab nce siab - dhau los ua kev kos duab qhia los ntawm kev sim ua kom muaj zog thiab, hais ncaj ncees, qee qhov kev sim thiab yuam kev. Koj tsis yog ua qhov tsis zoo ntawm ib feem; koj tab tom tsim lub tshuab thermal ib ntus. Cov neeg ntawm Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) tau qhov no. Nrog rau lawv cov keeb kwm yav dhau los 30 xyoo, lawv tau pom yuav ua li cas lub ntiajteb txawj nqus tau tsim zoo hauv cov xuab zeb lossis resin-bonded pwm tuaj yeem tsim cov khoom ntom ntom thiab cov khoom siv tshuab uas sib tw cov txheej txheem kim dua rau qee cov tsev neeg. Nws yog hais txog harnessing lub ntuj ntws, tsis sib ntaus nws.
Cov khoom xaiv yog lwm txheej. Peb tab tom tham cam khwb cia hlau, qee cov hlau, thiab qhov tseem ceeb, cov hlau ua haujlwm siab. Pouring nickel-raws li alloy nyob rau hauv lub ntiajteb txawj nqus yog ib tug tsiaj nyaum sib txawv dua li grey hlau. Thaum tshav kub kub yog khaus ntau dua, fluidity hloov, thiab cov pwm cov khoom tshuaj tiv thaiv yog ib qho kev txhawj xeeb tiag tiag. Koj tsis tuaj yeem siv tib daim ntawv qhia biscuit rau txhua pluas noj.
Qhov twg nws ci (Thiab qhov twg nws tsis)
Yog li thaum twg koj xaiv nws? Rau qhov nruab nrab mus rau qhov loj nrog cov phab ntsa tuab, nws feem ntau yog tus nqi zoo tshaj plaws ntawm cov hlau tsim tawm muaj. Xav tias lub hauv paus tshuab, cov iav loj loj, lossis cov khoom siv rau cov khoom hnyav. Tus nqi cuab yeej rau cov pwm yog qis dua rau kev kub siab tuag-casting, thiab koj tuaj yeem ua tiav cov txheej txheem sab hauv nrog cov xuab zeb cores.
Tab sis ntawm no yog qhov kev ua tau zoo: cov kaum sab xis. Vim tias koj tsis txhaj tshuaj hlau nyob rau hauv qhov siab, koj xav tau cov qauv dav dav rau kev tshem tawm cov qauv. Kuv tau muaj cov neeg tsim qauv xa cov khoom nrog ze-ntug phab ntsa, optimized rau machining, thiab ces balk ntawm qhov pom zoo 3-degree cua ntsawj ntshab. Koj yuav tsum piav qhia tias qhov kev xaiv ntawm gravity pwm casting dictates tej yam kev ywj pheej tsim thiab kev txwv. Nws yog ib qho kev sib tham ntawm qhov zoo tagnrho cov duab thiab cov tswv yim kev muaj tiag ntawm rub tus qauv los ntawm compacted xuab zeb.
Qhov saum npoo tiav yog lwm qhov qhia. Lub ntiajteb txawj nqus zoo xuab zeb casting yuav muaj tus yam ntxwv gritty kev ntxhib los mos, ib qho ncaj qha imprint ntawm cov xuab zeb. Nws tsis yog qhov tsis zoo; nws yog kos npe. Yog tias koj xav tau daim iav zoo li lub ntsej muag, koj tab tom saib cov txheej txheem xws li peev casting lossis plhaub molding - uas, tsis yog coincidentally, yog lwm yam tshwj xeeb ntawm lub khw zoo li QSY. Lawv yuav yog thawj tus qhia rau koj tias kev xaiv tus txheej txheem yog tsob ntoo ntawm kev txiav txim siab, pib nrog qhov ua haujlwm thiab xaus nrog tus nqi tag nrho.
Machining Handshake
Qhov no yog qhov tseem ceeb: tsis muaj lub ntiajteb txawj nqus-cam khwb cia yog ib kob. Nws yuav luag ib txwm mus rau machining. Tias yog vim li cas kev sib raug zoo ntawm cov foundry thiab lub khw muag khoom yog li intimate. Ib qho kev hloov pauv tsis zoo los ntawm ob peb millimeters yuav pom tsis pom ntawm cov khoom siv raw tab sis yuav ua rau lub chaw machining qw, tsoo cov cuab yeej thaum nws sim ntaus qhov nominal qhov ntev ntawm phab ntsa uas tam sim no nyias dhau lawm.
Peb tau tsim txoj cai yooj yim tab sis muaj txiaj ntsig: rau cov yam ntxwv tseem ceeb, peb yuav tso cov khoom lag luam ntxiv rau ntawm cov duab kos, tab sis peb kuj yuav xa thawj tsab xov xwm casting mus rau CMM nrog rau kev tsim kho tshuab. Qhov no tso cai rau CNC programmers ntawm machining theem - txawm nyob hauv tsev lossis ntawm tus khub zoo li QSY uas ua ob qho tib si casting thiab CNC machining-kom pom qhov tseeb li-cam khwb cia datum nto thiab kho lawv cov ntsiab lus xoom raws li. Nws hloov cov khoom seem rau hauv cov khoom siv tau. Kev sib koom ua ke ntawm casting thiab machining nyob rau hauv ib lub ru tsev, raws li lawv muaj, tshem tawm qhov sib txawv loj heev. Cov kws kho tshuab tuaj yeem tham ncaj qha rau cov neeg tsim khoom lag luam txog qhov chaw nyuaj lossis qhov tsis xav tau.
Cov ntaub ntawv QSY cov npe, zoo li cobalt-based alloys, yog ib qho piv txwv zoo meej. Casting lawv yog ib qho nyuaj; machining lawv yog lwm qhov kev txiav txim ntawm qhov nyuaj. Muaj tag nrho cov txheej txheem kev tswj hwm los ntawm ib pab neeg nrog kev paub ntau ntxiv txhais tau hais tias lub chaw tsim khoom tuaj yeem kho cov kev kho cua sov me ntsis raws li kev tawm tswv yim los ntawm cov khoom siv hauv pem teb txog cov cuab yeej hnav, tsim kom muaj txiaj ntsig zoo lub voj voog koj tsuas yog tsis tau nrog cov neeg muag khoom tsis sib haum.
Kev Sib Tham Hauv Ntiaj Teb Tiag: Zaj Dab Neeg Bracket
Kuv nco qab lub bracket rau ib tug offshore rig. Cov ntawv luam tau hu rau cov hlau tsis muaj steel hlau, cov qauv tsim nyog, thiab ob peb qhov dhuav nrog kev ua haujlwm nruj. Thawj qhov kev xav yog peev casting rau precision. Tab sis ib feem yog qhov loj ntawm lub thawv ntim khoom - kev nqis peev rau qhov ntim ntawm cov hlau yuav raug txwv tsis pub kim.
Peb npaj ib tug hybrid: gravity pwm casting rau lub cev tseem ceeb, siv cov tshuaj sib xyaw ua ke xuab zeb pwm kom zoo dua qhov kev ruaj ntseg zoo dua li cov xuab zeb ntsuab, thiab tom qab ntawd casting hauv precision-loj steel inserts rau qhov tseem ceeb qhov chaw. Cov inserts no yuav dhau los ua ib feem ntawm qhov casting. Thaum lub sij hawm machining, koj yuav laum rau hauv cov hlau ntxig, tsis yog cov cam khwb cia hlau, lav qhov kam rau ua. Nws yog me ntsis unorthodox, tab sis nws ua haujlwm. Cov txheej txheem lub ntiajteb txawj nqus tau muab peb cov huab hwm coj thiab cov duab kev lag luam, thiab cov khoom siv embedded daws qhov teeb meem precision. Nws yog hom pragmatic, hla txheej txheem kev xav uas txhais lub ntiaj teb kev tsim khoom tiag tiag.
Hom tsis ua hauj lwm? Thawj ncuav. Peb tsis tau preheat cov hlau ntxig txaus. Cov hlau molten tsoo cov hlau txias tsim ib qho chaw txias txias uas yog nkig. Nws dhau qhov kev kuaj pom tab sis ua tsis tiav kev kuaj ultrasonic. Zaj Lus Qhia: Txhua yam uas koj muab tso rau hauv pwm, txawm tias nws tsis yog ib feem ntawm cov qauv, ua ib feem ntawm lub thermal system. Peb daws nws los ntawm kev muab cov ntxig rau hauv qhov cub ua ntej pwm sib dhos. Yooj yim kho, tab sis koj tsuas kawm tau los ntawm kev ua, lossis ua tsis tau ib zaug.
Tshaj qhov Pour: Qhov Tsis Pom Qhov Hloov Pauv
Thaum kawg, cia peb tham txog qee yam tsis tshua muaj nyob hauv spec: tib neeg yam. Cov txuj ci ntawm tus pourer yog kab kawg ntawm kev tiv thaiv. Nws tab tom saib daim tawv nqaij hlau ntawm lub rooj vag, txiav txim siab sau tus nqi los ntawm lub nraub qaum-siab nws xav tau los ntawm lub ladle. Puas yog cov pwm haus cov hlau zoo, lossis puas yog nws gulping thiab yuav ntxiab cua? Qhov no tsis yog automation; nws yog kev paub. Hauv kev ua haujlwm zoo, tus neeg no muaj txiaj ntsig zoo ib yam li tus kws tshaj lij uas tsim lub rooj vag.
Tom qab ntawd muaj kev tos tom qab casting. Koj cia nws nyob hauv pwm ntev npaum li cas? Tso nws tawm ntxov dhau, thiab koj muaj kev pheej hmoo cuam tshuam los yog tawg los ntawm qhov tsis sib xws. Tos ntev dhau lawm, thiab koj tua koj lub sijhawm ntau lawm. Rau ib qho nyuaj steel casting, peb yuav cia nws txias hauv pwm thaum hmo ntuj. Rau ib daim hlau yooj yim, ob peb teev. Muaj ib txoj cai ntawm tus ntiv tes xoo, tab sis koj feem ntau lees paub nws los ntawm kev kuaj xyuas qhov kub ntawm qhov chaw thermal nrog kev sojntsuam.
Thaum kawg, gravity pwm casting yog ib qho pov thawj rau kev ua haujlwm nrog physics, tsis tawm tsam nws. Nws xav tias tseem ceeb vim nws yog. Nws xav tau kev hwm rau tag nrho cov saw: cov khoom siv tshawb fawb, pwm engineering, thermal tswj, thiab kev ua kom zoo. Nws tsis yog cov lus teb rau txhua qhov teeb meem casting, tab sis thaum qhov geometry, ntim, thiab cov khoom sib haum nrog nws cov kev ua tau zoo, nws tseem yog qhov sib xyaw ua ke ntawm kev ntseeg siab, zoo, thiab tus nqi - qhov tseeb ua haujlwm ntawm kev lag luam. Cov khw uas tau kav ntau xyoo lawm, zoo li QSY, nkag siab qhov sib npaug ntawm lawv cov pob txha, tsis yog lawv cov ntawv qhia xwb.
