Dab tsi yog cov txiaj ntsig ntawm cov ntxhia casting marble txaj machining chaw?
Mineral castings (man-made granite aka resin pob zeb) tau txais dav hauv kev lag luam tshuab cuab yeej rau ntau tshaj 30 xyoo ua cov khoom siv.
Raws li kev txheeb cais, hauv Tebchaws Europe, ib qho ntawm txhua 10 lub tshuab cuab yeej siv cov ntxhia castings ua lub txaj.Txawm li cas los xij, kev siv cov kev paub tsis tsim nyog, cov ntaub ntawv tsis tiav lossis cov ntaub ntawv tsis raug tuaj yeem ua rau muaj kev tsis txaus siab thiab kev txiav txim siab rau Mineral Castings.Yog li ntawd, thaum ua cov cuab yeej tshiab, nws yog ib qho tsim nyog los tshuaj xyuas qhov zoo thiab qhov tsis zoo ntawm cov ntxhia castings thiab sib piv nrog lwm cov ntaub ntawv.
Lub hauv paus ntawm kev tsim kho tshuab feem ntau muab faib ua cam khwb cia hlau, ntxhia casting (polymer thiab / lossis reactive resin qhob), steel / welded qauv (grouting / non-grouting) thiab ntuj pob zeb (xws li granite).Txhua yam khoom muaj nws tus yam ntxwv, thiab tsis muaj cov khoom siv zoo meej.Tsuas yog los ntawm kev tshuaj xyuas qhov zoo thiab qhov tsis zoo ntawm cov khoom siv raws li cov txheej txheem tshwj xeeb, tuaj yeem xaiv cov khoom siv zoo tagnrho.
Ob lub luag haujlwm tseem ceeb ntawm cov khoom siv - lav qhov geometry, txoj haujlwm thiab lub zog nqus ntawm cov khoom, feem ntau muab cov kev xav tau ntawm kev ua haujlwm (zoo li qub, dynamic thiab thermal kev ua tau zoo), kev ua haujlwm / cov qauv (qhov tseeb, qhov hnyav, phab ntsa tuab, yooj yim ntawm kev taw qhia rails) rau cov ntaub ntawv installation, media circulation system, logistics) thiab cov nqi yuav tsum tau (nqi, kom muaj nuj nqis, muaj, system yam ntxwv).
I. Cov kev xav tau ntawm kev ua haujlwm rau cov khoom siv
1. Cov yam ntxwv zoo li qub
Cov kev ntsuas rau kev ntsuas cov khoom zoo li qub ntawm lub hauv paus feem ntau yog qhov nruj ntawm cov khoom - qhov tsawg kawg deformation nyob rau hauv load, es tsis muaj zog.Rau qhov zoo li qub elastic deformation, ntxhia castings tuaj yeem xav tias yog cov khoom siv isotropic homogeneous ua raws Hooke txoj cai.
Qhov ceev thiab elastic modulus ntawm ntxhia castings yog feem 1/3 ntawm cov hlau cam khwb cia.Txij li cov ntxhia castings thiab cam khwb cia hlau muaj tib yam nruj nruj, nyob rau hauv tib qhov hnyav, lub rigidity ntawm hlau castings thiab ntxhia castings yog tib yam yam tsis xav txog qhov cuam tshuam ntawm cov duab.Feem ntau, cov qauv tsim phab ntsa thickness ntawm cov ntxhia castings feem ntau yog 3 npaug ntawm cov hlau castings, thiab cov qauv tsim no yuav tsis ua rau muaj teeb meem ntawm cov khoom siv los yog cov khoom siv.Mineral castings yog tsim rau kev ua haujlwm hauv qhov chaw zoo li qub uas muaj lub siab (xws li txaj, kev txhawb nqa, kab) thiab tsis haum raws li nyias-walled thiab / los yog cov thav ntawv me me (xws li cov rooj, pallets, cov cuab yeej hloov pauv, cov tsheb thauj khoom, kev txhawb nqa spindle).Qhov hnyav ntawm cov khoom siv feem ntau yog txwv los ntawm cov khoom siv ntawm cov chaw tsim khoom hauv pob zeb, thiab cov khoom siv hlau casting saum toj no 15 tons feem ntau tsis tshua muaj.
2. Cov yam ntxwv dynamic
Qhov ntau dua qhov kev sib hloov ceev thiab / lossis acceleration ntawm lub ncej, qhov tseem ceeb tshaj qhov kev ua tau zoo ntawm lub tshuab yog.Qhov chaw nrawm nrawm, hloov cov cuab yeej ceev, thiab cov khoom noj ceev ceev tsis tu ncua ntxiv dag zog rau cov neeg kho tshuab resonance thiab dynamic excitation ntawm lub tshuab yam ntxwv.Ntxiv nrog rau qhov tsim qauv ntawm cov khoom siv, qhov deflection, kev faib tawm ntau, thiab kev nruj nruj ntawm cov khoom yog cuam tshuam zoo heev los ntawm cov khoom damping ntawm cov khoom.
Kev siv cov ntxhia castings muab kev daws teeb meem zoo rau cov teeb meem no.Vim nws absorbs vibrations 10 npaug zoo dua li cov tsoos cam khwb cia hlau, nws tuaj yeem txo qhov amplitude thiab ntuj zaus.
Hauv kev ua haujlwm xws li machining, nws tuaj yeem nqa tau siab dua, zoo dua qhov zoo, thiab lub neej ntev dua.Nyob rau tib lub sijhawm, hais txog kev cuam tshuam lub suab nrov, cov ntxhia castings kuj ua tau zoo los ntawm kev sib piv thiab kev txheeb xyuas cov hauv paus, kis tau tus mob castings thiab accessories ntawm cov khoom sib txawv rau cov cav loj thiab centrifuges.Raws li qhov cuam tshuam lub suab tsom, cov pob zeb hauv av tuaj yeem ua tiav qhov txo qis hauv zos ntawm 20% hauv suab siab.
3. Cov khoom cua sov
Cov kws tshaj lij kwv yees tias kwv yees li 80% ntawm cov cuab yeej siv tshuab sib txawv yog tshwm sim los ntawm cov teebmeem thermal.Cov txheej txheem cuam tshuam xws li cov khoom siv hluav taws xob sab hauv lossis sab nraud, preheating, hloov workpieces, thiab lwm yam yog txhua yam ua rau thermal deformation.Txhawm rau kom muaj peev xwm xaiv cov khoom siv zoo tshaj plaws, nws yog ib qho tsim nyog yuav tsum tau qhia meej txog cov khoom siv.Cov cua kub tshwj xeeb thiab qis thermal conductivity tso cai rau cov pob zeb hauv av kom muaj cov thermal inertia zoo rau qhov kub thiab txias cuam tshuam (xws li hloov cov khoom ua haujlwm) thiab qhov kub thiab txias hloov pauv.Yog hais tias yuav tsum tau ceev preheating zoo li lub txaj hlau los yog lub txaj kub yog txwv tsis pub, cov cua sov los yog cua txias tuaj yeem ncaj qha mus rau hauv cov ntxhia casting los tswj qhov kub thiab txias.Kev siv cov cuab yeej ntsuas kub no tuaj yeem txo qhov deformation los ntawm kev cuam tshuam ntawm qhov kub thiab txias, uas yuav pab txhim kho qhov tseeb ntawm tus nqi tsim nyog.
II.Kev ua haujlwm thiab cov qauv tsim nyog
Kev ncaj ncees yog qhov txawv ntawm qhov txawv ntawm cov pob zeb hauv av los ntawm lwm cov ntaub ntawv.Qhov siab tshaj plaws casting kub rau cov ntxhia castings yog 45 ° C, thiab ua ke nrog high-precision pwm thiab cov cuab yeej, qhov chaw thiab cov ntxhia castings tuaj yeem raug cam khwb cia ua ke.
Advanced re-casting cov txheej txheem kuj tseem siv tau rau cov pob zeb hauv av casting blanks, uas ua rau cov mounting meej thiab rail qhov chaw uas tsis tas yuav machining.Zoo li lwm cov ntaub ntawv hauv paus, cov ntxhia castings raug rau cov qauv tsim tshwj xeeb.Phab ntsa thickness, load-bearing accessories, rib inserts, loading thiab unloading txoj kev yog tag nrho cov txawv los ntawm lwm yam ntaub ntawv mus rau ib tug tej yam, thiab yuav tsum tau txiav txim siab ua ntej thaum tsim.
III.Cov nqi xav tau
Txawm hais tias nws yog ib qho tseem ceeb uas yuav tsum tau xav txog los ntawm kev pom zoo, kev ua tau zoo ntawm tus nqi yog nce qhia nws qhov tseem ceeb.Siv cov ntxhia castings tso cai rau cov kws ua haujlwm kom txuag tau cov nqi tsim khoom thiab kev ua haujlwm tseem ceeb.Ntxiv rau kev txuag ntawm cov nqi machining, casting, kev sib dhos zaum kawg, thiab nce nqi logistics (warehousing and transport) yog tag nrho cov txo raws li.Xav txog qhov kev ua haujlwm siab ntawm cov ntxhia castings, nws yuav tsum tau saib raws li qhov project tag nrho.Qhov tseeb, nws yog qhov tsim nyog ntau dua los ua tus nqi sib piv thaum lub hauv paus tau teeb tsa lossis ua ntej.Tus nqi pib kuj yog tus nqi ntawm cov ntxhia casting pwm thiab cov cuab yeej, tab sis tus nqi no tuaj yeem diluted hauv kev siv mus ntev (500-1000 daim / hlau pwm), thiab kev noj txhua xyoo yog li 10-15 daim.
IV.Scope ntawm kev siv
Raws li cov khoom siv, cov ntxhia castings tau hloov pauv cov khoom siv niaj hnub, thiab tus yuam sij rau nws txoj kev loj hlob sai yog nyob rau hauv cov ntxhia casting, pwm, thiab cov khoom sib txuas ruaj khov.Tam sim no, cov ntxhia castings tau siv dav hauv ntau lub tshuab cuab yeej xws li kev sib tsoo tshuab thiab kev ua haujlwm siab.Sib tsoo tshuab manufacturers tau pioneers nyob rau hauv lub tshuab cuab tam sector siv ntxhia castings rau tshuab txaj.Piv txwv li, cov tuam txhab muaj npe nrov hauv ntiaj teb xws li ABA z&b, Bahmler, Jung, Mikrosa, Schaudt, Stude, thiab lwm yam tau yeej ib txwm tau txais txiaj ntsig los ntawm damping, thermal inertia thiab kev ncaj ncees ntawm cov ntxhia castings kom tau txais qhov siab precision thiab zoo heev hauv cov txheej txheem sib tsoo. .
Nrog ib puas-nce dynamic loads, ntxhia castings kuj tau nce kev nyiam los ntawm lub ntiaj teb-ua tuam txhab uas muag nyob rau hauv lub teb ntawm cov cuab yeej grinders.Cov pob zeb hauv av casting txaj muaj rigidity zoo heev thiab tuaj yeem tshem tawm cov quab yuam los ntawm kev nrawm ntawm lub cev muaj zog.Nyob rau tib lub sijhawm, kev sib xyaw ua ke ntawm cov organic sib xyaw ua ke ntawm kev ua haujlwm zoo ntawm kev vibration absorption thiab linear motor tuaj yeem txhim kho qhov zoo ntawm qhov chaw ua haujlwm thiab kev pabcuam lub neej ntawm lub log sib tsoo.
