Kev tuag casting pwm gating system pom qhov kev txaus thiab lub xeev ntawm cov kua filling, thiab plays lub luag haujlwm tseem ceeb hauv kev txo cov pores thiab cov impurities ntawm cov tuag casting thiab tau txais ib lub qauv ntom. Yog li, qhov kev xaiv ntawm daim ntawv foos gating no tseem ceeb heev. Yuav kom txo cov ndlwg ntawm cov hlau, cov qauv hauv qhov tuag yog qhov sib txuam, thiab lub qhov rooj hauv plawv yog siv los rau hauv. Tus txheej txheem muaj qhov zoo ntawm kev khiav qis, kev hloov ntawm kev sib hloov, kev sib hloov ntawm kev sib hloov, kev sib sau ua haujlwm, kev ua pa, thiab kev yoojyim, thiab tsis tuaj yeem ua rau lub siab ntsuav ntawm qhov kabmob hauv qhov tuag casting thiab pabcuam tuag casting.
Txawv los ntawm kev tuag castings zoo tib yam, lub qauv rotor ntawm micro-motors zoo li yuav yooj yim, tab sis phab ntsa thickness txawv heev. Lub phab ntsa ntawm qhov kawg, cov hlua thiab daim ntawv qhia strips yog nyias thiab nyias. Yog hais tias cov pwm tsim tsis tsim nyog, nws yuav ua rau shrinkage, loosening, porosity, nrog rau cov kev tuav cov khoom tuav thiab tsis khov ntawm lub kiv cua hniav.
Daim duab rotor seem muaj ob kawg rings ntawm txhua kawg. Qhov ntev yog 12 hli thiab 6 hli, feem. Xeem 6 hli kawg yog tus qauv tsim: Tian Fuxiang, txiv neej, yug xyoo 1951, xib fwb.
Rau qhov pub rooj vag pub, kawg 12 hli ntiv nplhaib tau muab tso rau hauv qab ntawm cov kab noj hniav.
Thaum tuag casting, cov txhuas ua kua nyob rau sab saum toj ntawm kab noj hniav ua ntej. Yog li ntawd, hauv qab ntawm cov kab noj hniav yuav tsum muaj lub peev xwm ua kom zoo. Txwv tsis pub, cov teeb meem xws li cov blowholes thiab filling dissatisfaction tej zaum yuav tshwm sim vim yog tsis txaus siv pa roj pa. Yog li, ib qho chaw nres tsheb uas muaj qhov dav ntawm 18 hli thiab ib lub qhov tob ntawm 0.1 hli tau qhib rau hauv qab ntawm cov qauv khov. Tib lub sijhawm, cov txheej txheem ntawm inserting inserts thiab inserting tsho nyob rau hauv txav thiab taag tuaj pwm siv los pab cov tawm ntawm cov roj thaum tuag casting txheej txheem, qhov no daws cov teeb meem ntawm lub pob zeb ntawm cov castings, txo cov khib nyiab los ntawm blowholes, thiab txhim kho kev tsim nyog ntawm kev tuag castings. Los ntawm tsim cov khoom seem hauv cov pwm kab ua ke raws li cov ntawv pov thawj thiab cov ntaws, cov cuab yeej hlau tau txais kev cawmdim, thiab cov ntawv ntim thiab cov hlua yuav tsim tau yooj yim. Los ntawm kev hloov lub hau ntim thiab cov thawv ntawv, qhov hloov tshiab ntawm cov pwm yog txo.
Lub
Txoj kev tuag thiab txoj kev tuag hauv CAD yuav ua kom luv nqi tsim, txo nqi, thiab ua kom cov khoom sib tw, uas tau txais kev saib xyuas hauv tsev thiab txawv teb chaws. Tam sim no, muaj ob hom kev tsim kho qhov tsim tawm. Ib qho yog tsim los ntawm kev tsim kho txhua yam ntawm CAD-CAM software, xws li UG thiab Pro / Engineei hauv Tebchaws Meskas; qhov sib txawv ntawm qhov kev tsim cov lus programming nyob hauv Windows environment los sau CAD cov txheej txheem. Cov cheebtsam sab nrauv qhov kev kawm tseem ceeb yog tsim los ntawm lwm cov software. Pro / E yog CAD / CAM software uas tsim los ntawm PTC thiab tsim cov khoom tsim, kev sib txoos khoom, kev tsim kho, kev tswj kev ua zauv, kev tsim hlau, tsim qauv, thiab qauv CAD / CAM kev koom ua ke. Kev tuag casting pwm raug muab tso rau pem hauv ntej kom paub tseeb CAD, ntsuas phom rov qab, thev xaib, ntsuas sim, kev ntsuam xyuas kev ntxhov siab thiab kev tswj cov ntaub ntawv. Rau cov kev haumxeeb no ntawm Pro / E, ib txoj kev tshiab raws li Pro / E rau kev tuag-casting mould CAD.
1 Tsim Cov Txheej Txheem thiab Tsim Qauv Txheem ntawm Tuag Casting Dies Tuag casting tuag yog ib yam khoom tseem ceeb rau kev tuag casting ntau lawm. Qhov zoo thiab qhov tsis zoo ntawm kev tuag casting tuag tsim ncaj qha rau cov duab, qhov loj, lub zog, qhov zoo, thiab lwm yam. Tuag castings, ces tuag casting tuag tsim tsim nyog yuav tsum ua raws li nram qab no: Tus Txheej Txheem: Adapt mus rau ntau yam kev xav ntawm kev tuag casting , thiab muab cov castings tuag uas ua tau raws li qhov yuav tsum tau kos duab.
Qhov kev kawm siab tshaj plaws yog muab tso rau ntawm tus qauv tsim thiab muab xam rau ntawm txoj hlua (gating system) kom txo tau cov qoob loo rau castings.
Kev siv cov cuab yeej tsim kom ntau tshaj li qhov ua tau kom luv tau tsim thiab tsim kev xyaum ua haujlwm qhia tias cov pa roj carbon lim dej thiab cov hmoov zeb casting zoo zoo, cov castings yog kuaj los ntawm lub tshuab xoo hluav taws xob, lub bar thiab lub nplhaib hlau tawg yog ntau dua compact, non-porous, thiab qhov tsos deg yog du, tsis muaj txias septum thiab lwm yam tsis xws luag.
2 Pwm haujlwm txujci Thaum pwm nyob rau hauv txoj hauv kev qhib siab, lub hauv paus muaj rotor tseem muab tso rau hauv cov kab noj hniav. Thaum tuag-casting, cov tshuaj kua txhuas hauv cov khoom siv lub tog raj kheej thawb tawm ntawm lub hau los ntawm tus khiav ntawm lub laub tuag casting tshuab thiab txhaj rau hauv cov kab noj hniav ntawm lub qhov rooj ntawm sab hauv. Tom qab tawm hauv lub pwm rau 12s, lub pwm qhib. Nyob rau hauv qhov kev txiav txim ntawm tus nrig ntawm lub plhaub tuag casting lub cav, cov workpiece yog raug tshem tawm ntawm daim phaj saum toj kawg nkaus 21 mus txog lub pins 3, 4. Thaum lub puab kaw lawm, lub phaj sab saum toj yog rov pib dua ntawm qhov pib dua 23.
3 Kev Txhim Kho Cov txheej txheem tsis muaj kev pov thawj tsis muaj kev txwv kev tiv thaiv, puv nqi, tuag casting kub, kab noj kab noj hniav, pwm tuav lub sijhawm thiab lwm yam.
Qhov kev siab zoo muaj kev cuam tshuam zoo rau lub peev xwm ntawm cov hlau ua kom tiav cov kab noj hniav, lub zog thiab kev cog ntawm lub casting. Ib qhov kev siab dua tuaj yeem ua rau lub zog thiab kev cog lus ntawm kev pov thawj, tiam sis muaj kev siab dua yuav txo qhov kev pab cuam tuag ntawm lub pluaj casting pwm, ua rau muaj kev xav ua kom khaus, thiab txo qhov kev nruj nruj ntawm qhov casting. Cov txheej txheem no tshaj qhov siab yog teeb tsa txog 52MPa filling tus nqi yog qhov tseem ceeb tshaj uas cuam tshuam rau qhov zoo ntawm cov tsos ntawm casting. Tus ndlwg ntawm tus molten hlau nyob ntawm qhov kev hloov yog nyob hauv thaj tsam ntawm 20 m / s. * C.
Nyob rau hauv cov khoom ua tuag, kev ua kom cov pwm kub qhov ntev tuaj yeem ua rau cov yeeb yaj kiab, cov khoom ua tau zoo thiab kev ua haujlwm ntawm lub pwm. Kev ntsuas kub ntau yam yog 200 ~ 250.0. Lub sij hawm ncua sij hawm yog txog li 3s per millimeter rau nruab nrab phab ntsa thickness ntawm casting. Rotor retention lub sij hawm yuav tsum tau xaiv raws li tus qauv rotor. Lub sij hawm retention yog luv heev thiab yuav cuam tshuam qhov zoo ntawm rotor tuag casting. Ntau ntev yuav cuam tshuam rau cov khoom noj. zoo heev. Casting lub sijhawm yog 12s. 4 cov lus xaus Cov kev xyaum ua haujlwm qhia tau hais tias cov tuag tuag casting muaj cov qauv tsim nyog, txhim khu kev txhim khu kev siv pa, kev siv yooj yim thiab yooj yim, tsis tas siv lub rotor nti rau cua sov, lub neej ntev ntev, zoo casting zoo thiab cov khoom ua tau zoo.
