Casting txoj kev ntawm hlau hmoov txhaj tshuaj molding
Hlau hmoov metallurgy yog ib hom kev siv tshuab uas siv cov hmoov hlau ua cov khoom siv los ua cov hlau los yog cov hlau alloy los ntawm molding thiab sintering. Cov kws ua lag luam hauv kev lag luam Mim tuaj yeem ntxeem tau ncaj qha rau cov ntaub ntawv tsis zoo lossis cov khoom siv sib ntswg thiab cov khoom siv no, yog li nws tau siv dav.
Preformed blanks yog ib qho tseem ceeb heev ntawm cov hmoov casting hauv hlau hmoov metallurgy txhaj tshuaj molding (MIM) technology. Raws li cov kev xav tau ntawm cov khoom lag luam casting, nws yog ib qho tsim nyog los npaj cov txheej txheem ntawm cov ntaub ntawv ib feem, xaiv cov ntaub ntawv, npaj cov duab ntawm qhov chaw, txiav txim siab cov txheej txheem casting, thiab tom qab ntawd nkag mus rau hauv kev npaj ntawm preformed blanks thiab pwm ua. Dab tsi yog cov txheej txheem casting ntau lawm? Los ntawm kev paub txog kev tshaj lij, Zhongwei Precision tau sau cov qauv hauv qab no rau MIM thev naus laus zis hauv kev ua haujlwm zoo.
1. Flap casting: Cov duab ntawm lub preform tsim los ntawm no casting yog qhov yooj yim, thiab cov duab ntawm ib feem yog thaum kawg tau los ntawm casting. Nyob rau hauv tus txheej txheem ntawm pier forging, cov hmoov txav mus tom qab kom txog thaum nws hla lub pwm kab noj hniav, thiab muaj ob peb flash extruded los ntawm pwm kaw seam ze ntawm lub casting los tsim flash, uas yuav tsum tau ob peb tom qab machining.
2. Kaw casting yam tsis muaj flash: lub preform zoo ntawm no casting txoj kev kuj kuj yooj yim. MIM cov kws tshaj lij pom tau tias ntau txoj hauv kev casting kuj dhau los ntawm pwm kab noj hniav los ntawm kev txav mus los ntawm cov hmoov, tab sis cov txheej txheem preform yog tswj, thiab cov pwm kaw lub siab yog loj, yog li cov khoom casting tsis muaj flash thaum kawg ua tiav.
3. Kub re pressing casting txoj kev: lub preform puab tsim los ntawm no casting txoj kev yog heev zoo ib yam li txoj kev forging tom qab tag nrho, yog li muaj me ntsis lateral txav deformation ntawm hlau nyob rau hauv kub forging. Nyob rau hauv lub kaw tuag kab noj hniav, nws yog tsuas yog lub refinement txheej txheem ntawm axial ntshiab compression, uas yog suav hais tias raws li kev loj hlob ntawm kev sib xyaw ntawm hmoov metallurgy kub nias thiab txias re pressing tshuab.
Lub shrinkage ntawm sintered hlau hmoov txhaj tshuaj molding yog muaj feem xyuam rau cov pwm geometry thiab txhaj tshuaj, tab sis nws yog zoo ib yam nyob rau hauv cov khoom molded. Cov ntsiab lus saum toj no feem ntau yog hais txog txoj kev casting ntawm hlau hmoov txhaj tshuaj molding, thiab peb vam tias nws tuaj yeem pab koj
