Kev nqis peev txheej txheem is los ua ib tug qauv nrog siv quav ciab, qhwv ib txheej ntawm av nplaum thiab lwm yam refractories rau nws saum npoo, tshav kub ua kom cov ciab yaj thiab ntws tawm, thiaj li kom tau txais lub plhaub npliag tsim los ntawm refractories, thiab tom qab ntawd yaj cov hlau thiab ncuav nws mus rau hauv lub plhaub tag, tom qab cov hlau ua kom txias, lub refractories yog zwm kom tau txais cov hlau pwm. Cov txheej txheem ntawm kev ua cov hlau yog hu ua precision casting, tseem hu ua kev lag luam casting lossis ciab poob casting.
Qhov zoo thiab tsis zoo ntawm kev nqis peev txheej txheem
Peev casting kuj tseem hu ua kev lag luam casting. Piv nrog rau lwm txoj kev casting thiab qhov chaw tsim txoj kev, peev casting muaj qhov zoo li nram no:
1. Lub tshuab casting muaj cov qhov siab siab thiab qhov kev ua tiav ntawm lub ntsej muag zoo nkauj. Qhov ntev ntawm qhov tseeb ntawm qhov casting tuaj yeem ncav cuag 4-6 qib, thiab qhov saum npoo ntxig tuaj yeem ncav cuag 0.4-3. 2 μ m, uas tuaj yeem txo qhov hnyav ntawm cov tshuab ua haujlwm ntawm qhov casting, paub qhov kev tsim khoom yam tsis muaj kev tso cai thiab txo qis nqi ntau lawm.
2. Rau cov nruas pov tseg nrog cov qauv duab nyuaj thiab nyuaj rau kev tsim los ntawm lwm txoj kev, qhov sib txawv ntawm qhov ua haujlwm ntawm qhov kev xaiv yog me me li ob peb millimeters thiab loj li ntau txhiab millimeters, qhov tsawg tshaj plaws phab ntsa tuab yog 0. 5 hli, thiab txoj kab uas hla me dua li qhov tsawg tshaj li 1. 0mm.
3. Alloy cov ntaub ntawv tsis txwv: xws li carbon hlau, stainless hlau, alloy hlau, tooj liab alloy, aluminium alloy, kub kub alloy, titanium alloy thiab hlau muaj nqi thiab lwm yam ntaub ntawv tuaj yeem tsim los ntawm precision casting, tshwj xeeb tshaj yog rau cov ntaub ntawv alloy uas nyuaj rau forge, weld thiab txiav.
4. Muaj ntau lawm yooj thiab adaptability. Nws tuaj yeem siv tsis yog nyob rau hauv pawg ntau lawm, tab sis kuj hauv cov khoom me me lossis txawm tias ib qho khoom lag luam.
Yuav suav, precision casting muaj qhov zoo ntawm cov peev txheej me, peev txheej ntau lawm, tus nqi qis ntau lawm, cov txheej txheem yooj yim ntawm cov khoom nyuaj thiab cov peev txheej nrawm. Yog li, nws yog nyob rau hauv txoj haujlwm txaus siab hauv kev sib tw nrog lwm cov txheej txheem thiab cov txheej txheem tsim tawm.
Tab sis nyob rau hauv cov txheej txheem ntawm kev siv pwm ua pwm, cov tsis huv hauv qab no yog qhov yooj yim tshwm sim
1. Quav pwm pwm yog deformed. Tom qab cov pwm pwm coj tawm ntawm lub pwm, ntxiv rau qhov txo qis ntawm qhov loj me, qee zaum nws yuav poob rau kev txiav vim cov txheej txheem tsis yog thaum nws coj tawm. Raws li cov pwm ciab tau nquag tau khoov thiab deformed thaum nws txias, cov ciab pwm nyuam qhuav nqa tawm ntawm cov pwm yuav tsum tau muab tso kom zoo, feem ntau nrog lub dav hlau loj li lub dav hlau datum, lossis cov khoom siv quav ciab yuav ua tau mos muag heev, tsis tuaj yeem siv tau siab tsim thiab lwm yam.
2. Qhov laj thawj tseem ceeb rau cov ciab pwm txhawm rau kev tsis txaus siab yog tias qhov kub ntawm cov khoom siv quav ciab tsis dhau, qhov kev txhaj tshuaj qeeb qeeb, thiab cov pwm kub tsis txaus, uas ua rau cov khoom siv quav ciab kom txias sai hauv cov txheej txheem ntws, uas tau qhia hauv ntu ntawm lub ces kaum thiab ntug los yog nyias-phab ntsa ib feem ntawm siv quav ciab pwm txhawm rau kev tsis txaus siab, thiab lub ntsej muag tshwm ntawm lub ces kaum, uas zoo li tsis muaj qhov tsis sib xyaw ntawm cov hlau castings.
3. Muaj cov wrinkles nyob rau saum npoo ntawm ciab pwm. Vim tias qhov kub ntawm cov khoom siv quav ciab yog qhov tsawg heev thiab qhov nrawm ntawm kev txhaj tshuaj yog qhov tsawg heev, qhov txav ntawm cov khoom siv quav ciab thiab lub zog ntsuas kub tsis tau sib phim; los yog vim hais tias sab hauv puab ntawm nias pwm yog puas lawm lossis tsis huv; qhov chaw ntawm ntawj txias thaiv lub pob hlau tsis tsim nyog, thiab lwm yam, cov khoom siv txav tau sab laug ntawm cov nplauv pwm. Muaj cov kab sib sib zog nqus, zoo ib yam li cov rwb thaiv tsev txias qhov tsis xws ntawm cov hlau cam; tseem muaj cov pob qij txha nyob ib ncig ntawm lub ntsiab thiab qhov, uas yog me ntsis sunken. Qhov tseeb, qhov sib koom ua ke ntawm ob kwj ntawm cov ciab tsis zoo fused, uas yog los ntawm qhov tsis muaj peev txheej tsis txaus thiab siab ntawm siv quav ciab.
5. Qhov kev poob siab saum npoo ntawm cov ciab pwm yog feem ntau ua los ntawm kev txhaj tshuaj tsis txaus thiab lub sijhawm, siab siab siv quav ciab thiab lub sijhawm txias tsis txaus, qee zaum dhau los tso tus neeg sawv cev, thaj chaw loj ntawm kev nyuaj siab, nyuaj kho thiab yooj yim ua rau cov khoom pov tseg.
6. Cov pwm pwm muaj qhov khoob khoob khoob khoob khoob, uas yog qhov feem ntau qhov tsis xws luag, uas yog, muaj ntau heev heev siv quav ciab khiav tawm ntawm qhov sib koom tes ntawm cov nias pwm, qhov sib koom tes ntawm cov nias pwm ua ke, qhov sib koom tes ntawm cov tub ntxhais thiab tub ntxhais. lub rooj zaum, thiab lwm yam Vim li cas qhov tseeb ntawm kev tuag tsis txaus, lub ntsej muag muaj feem lossis qhov sib txuam ntawm sab hauv sab hauv ntawm lub cev tuag puas ntsoog lossis txuas nrog cov khoom tsis huv, lossis lub zog ntawm lub tuag tsis txaus, thiab txhaj ua ntshav siab dhau lawm. Los yog kub ntawm siv quav ciab yog siab dhau. Cov plaub ntug plaub ntug yuav tsum tau muab tshem tawm kom huv ua ntej ua ntej siv pwm.
7. Cov nplaum ntawm cov pwm pwm thiab nias pwm yog tshwm sim los ntawm tsis siv tus neeg tso tawm, kub dhau ntawm siv quav ciab thiab nias pwm, lossis sab hauv puab ntawm nias pwm yuav tsis huv txaus.
8. Qhov saum npoo ntawm cov ciab pwm yog ntxhib, vim tias qhov kev txhaj tshuaj tiv thaiv qis dhau lawm, lossis qhov sib kis ceev ntawm cov khoom siv quav ciab thiab sab hauv puab ntawm cov pwm tsis txaus, qhov hnyav yuav tshwm sim.
9. Muaj cov npuas nyob hauv cov pwm ciab, ib qho yog npuas sab saum toj pom rau qhov muag tsis pom, lwm qhov yog npuas sab hauv ntawm cov pwm ciab, uas feem ntau loj thiab tsis tuaj yeem pom los ntawm lub qhov muag liab qab, tab sis lawv tuaj yeem nrhiav tau los ntawm lub zos sib xyaw ntawm cov ciab pwm, uas tshwm sim los ntawm kev nthuav dav ntawm cov roj hauv cov pwm.
Cov ntsiab lus tseem ceeb ntawm kev ua lag luam casting txheej txheem
1. Tsis txhob tsuag rau ntau tus neeg sawv cev mus rau hauv cov kab noj hniav.
2. Tsis txhob hloov lub voj voog ncig ntawm nias thiab yaj (siv quav ciab) pwm.
3. Cov pwm pwm yuav tsum tau muab tso rau hauv lub tais ntim khoom thiab cais tawm ua ke kom tsis txhob muaj kev puas tsuaj. Cov ntaub qhwv tuaj yeem siv tau thaum tsim nyog kom tsis txhob deformation ntawm pwm pwm.
4. Ua tib zoo saib kom tsis txhob puas qhov profile thaum kho lus.
Cov txheej txheem siv ntawm peev txheej txheem txheej txheem
Precision casting yog siv nyob rau hauv yuav luag txhua qhov kev lag luam, tshwj xeeb tshaj yog hauv cov khoom siv hluav taws xob, roj av, tshuaj lom neeg kev lag luam, lub zog, tsheb thauj mus los, lub teeb pom kev lag luam, textile, chaw muag tshuaj, khoom siv kho mob, twj thiab li qub.
