Cov Txheej Txheem Tshawb Fawb
Nws yuav siv sij hawm tsawg dua 24 teev los hloov cov sib tov sib xyaw ntawm cov hlau mus rau hauv ib qho nyuaj, ntse txiav hniav nyob rau hauv cov duab uas yooj yim ua tsis tau los ntawm lwm txoj kev. Qinhuangdao Zhongwei tau ua tiav cov txheej txheem tsim khoom tshwj xeeb no los ntawm kev siv Hlau Txhaj Moulding (MIM). Thiab cov txheej txheem no tseem tab tom ua kom zoo - yav tom ntej ntawm kev siv tshuab nyob ntawm no.
Zhongwei Precision hauv Qinhuangdao yog nyob rau hauv cov txheej txheem kuaj ntawm Central South University. Lub kiv cua yog hloov tas li, thiab tib neeg tuaj yeem hnov ​​​​qhov "thump" lub suab ntawm lub tshuab txhaj tshuaj molding thaum lub sijhawm txhaj tshuaj molding. Lub tuam tsev R&D tseem tab tom txhim kho MIM cov txheej txheem uas tau coj mus rau CoroCut3 cov cuab yeej txiav tawm hauv xyoo 2003.
Wu Zhenliang, tus kws tshawb fawb thiab tus thawj tswj haujlwm ntawm Qinhuangdao Zhongwei Precision ntawm Central South University, tau hais tias: "Peb tau tsim ntau yam txheej txheem los ua kom zoo dua cov txheej txheem thiab cov khoom. rau cov txheej txheem tsim khoom tiag tiag. Siab dua thiab siab dua. "
MIM qhov chaw xa mus rau hlau txhaj tshuaj molding. Hauv cov ntsiab lus yooj yim, cov khoom sib xyaw (cov khoom sib xyaw) yog txau los yog txhaj rau hauv pwm lossis cov cuab yeej shaping. Kev siv cov tshuaj molding los tsim ntau yam tsis yog tshiab - nws tau ntev tau siv hauv kev lag luam yas.
Qinhuangdao tau tsim MIM txheej txheem rau precision rau 20 xyoo. Txhawm rau tsim CoroCut3, hmoov hlau yog tov nrog yas ua ntej txhaj rau hauv pwm. Qhov sib tov no, uas yog khoom nyob rau hauv chav tsev kub, yog thawj zaug poured rau hauv lub tog raj kheej nrog ib tug ntsia hlau sab hauv, thiab cov ntsia hlau pib tig. Cov lus tsa suab sib hloov thawb cov sib tov mus rau sab saum toj ntawm "screw" thaum sib tov yog rhuab thiab hloov los ntawm cov khoom mus rau ib nrab kua, ib yam khoom hu ua "billet". Nyob rau ntawm qhov kawg ntawm lub thoob, nce siab thawb lub hau ntswj rov qab mus rau hauv lub thoob kom txog thaum lub ntim ntim tau zoo. Lub billet, uas tau mus txog qhov kub ntawm txog 150-180 degree, yog ces txhaj rau hauv lub pwm pwm.
Txij li qhov kub ntawm cov cuab yeej pwm qis dua li ntawm qhov khoob, qhov khoob khoob khoob hauv pwm. Cov txheej txheem kho ntawm CoroCut3 feem ntau siv sijhawm 15 vib nas this, tom qab ntawd tus neeg hlau tshem tawm ib feem thiab muab tso rau ntawm lub phaj graphite.
Niaj hnub no, txawm li cas los xij, cov neeg ua haujlwm txhaj tshuaj molding tshem cov khoom ntawm tes. Nrog kev pab los ntawm cov kws tshawb fawb nyob rau hauv kev tshawb fawb thiab kev loj hlob department, nws tau soj ntsuam cov billet txhaj ntim, kub thiab txias lub sij hawm yuav tsum tau rau kev ua mim txhaj molded qhov chaw.
Tus neeg teb xov tooj hloov kho qhov kub thiab qhov loj ntawm billet los ntawm kev tswj vaj huam sib luag. Thaum lub workpiece solidified, nws muab cov hnab looj tes dawb los tshem tawm cov workpiece. "Qhov ntawd kuv tsis tau hlawv vim lawv tseem kub heev," nws hais.
Cov khoom raug tshem tawm los ntawm kev txhaj tshuaj molding yog qhov yooj yim heev thiab tuaj yeem tawg yog tias tuav nrog ntiv tes. Yas, ntawm qhov tod tes, tsuas yog ib txoj hlua khi uas yuav tsum tau muab tshem tawm. Qhov no txhais tau hais tias "lub cev ntsuab" yuav tsum tau ua ntxiv.
Thaum lub binder raug tshem tawm, qhib qhov pores yuav tshwm sim ntawm lub workpiece los pab txhawb txoj kev sintering, thiab lub workpiece yog compressed thaum lub sij hawm sintering. Thaum lub sij hawm sintering, lub workpiece yog rhuab mus txog 1400 degree nyob rau hauv lub cub tawg, yog li ntawd lub workpiece yuav shrinkage los ntawm 18 feem pua ​​​​rau 20 feem pua ​​​​, thiab cov duab tuaj yeem khaws cia zoo ib yam tom qab sintering.
Wu Zhenliang, tus thawj coj ntawm Zhongwei Precision Project, tau hais tias, "Yog hais tias lub ntim ntawm lub workpiece yog 1 liter, tsuas yog hais txog 550ml yuav tsum tau tso tseg tom qab sintering. Nyob rau hauv lwm yam lus, sintering yuav ua rau cov khoom condense los yog shrink kom ua tau raws li qhov xav tau hardness. , durability, toughness, thiab lwm yam.
Tom qab li ntawm 10 mus rau 12 teev, sintering tiav, thiab tom qab ntawd lub workpiece yog me ntsis ua tiav, thiab txhua ntug tiav, thiab tom qab ntawd cov txheej yog siv.
Wu Zhenliang, tus thawj tswj hwm ntawm qhov project, piav qhia, "Thaum lub sijhawm tsim khoom, peb feem ntau yuav tsum siv sijhawm ntau dua los sib tsoo thiab ua kom cov npoo npoo ua ntej txheej txheej hlau, tab sis nrog cov txheej txheem MIM, tsis tas yuav muaj qhov ua tiav tiav. txheej txheem .Qhov txiaj ntsig ntawm kev txhaj tshuaj molding yog tias peb tuaj yeem tsim cov grooves nyuaj lossis cov khoom hauv ib kauj ruam kom tiav lossis ib nrab tiav zoo.Peb tuaj yeem ncaj qha mus rau qhov kawg lub hom phiaj, uas yog vim li cas peb xaiv MIM qhov chaw.
