Kev Siv Die Casting: Qhia Tshiab Txog Kev Siv, Qhov Zoo, thiab Kev Txhim Kho Tsol

Qhov siab thiab qhov loj ntawm kev tsim hluas ntawm die casting uses yog ib qho tseem ceeb tshaj plaws rau cov neeg tsim khoom uas xav kom muaj kev tsim khoom ntau dua. Die casting uses tam sim no tuaj yeem tau txog qhov sijhawm cycle li 15-30 feeb rau cov ntaub ntawv leej, thaum cov ntaub ntawv loj thiab tseem ceeb dua feem ntau yuav xav tau 1-3 feeb nrog txhua qhov sijhawm. Qhov siab no tuaj yeem ua tau los ntawm qhov kev siv zog tshwj tsis siv tib neeg ntawm die casting uses, uas kawg metal hluas, kho, thiab tshuam cov ntaub ntawv nyob rau hauv qhov sijhawm luv luv. Qhov chaw injection siv zog siab yog qhov tseem ceeb rau die casting uses uas pab tso metal hluas rau hauv cavity nrog peb feeb, thim tso qhov sijhawm ntev uas pom nyob rau lwm qhov kev tsim hluas. Thaum injection laj lawm, qhov kev kho tshuaj xyuas nyob rau die casting uses siv qhov zog thermal ntawm cov dies hlwb los tshuab ntau tshav kub tawm ntawm cov ntaub ntawv, tshav kub ntau thiab zoo ib yam. Qhov kho siab no tsis yog tsuas yog pab tso kev tsim khoom ntau dua, tab sis kuj pab rau muaj qhov zoo tshaj rau kev tsim khoom los ntawm die casting uses los ntawm kev tsim microstructures me me uas pab ntxiv qhov tsim thiab kev nyiaj ruaj. Qhov kev tsim khoom loj ntawm die casting uses tsis yog tsuas yog qhov siab, tab sis kuj muaj kev zoo ib yam thiab kev txaus siab rau ob mils thiab tshaj qhov ntawd. Qhov kev tsim khoom meej pem ntawm die casting uses tso kom muaj qhov nrawm ib yam rau txhua qhov kev tsim khoom, tso kom cov ntaub ntawv thawj thiab ob mil tib lub tswv yim. Qhov zoo ib yam no tshem tawm qhov sib txawv thiab qhov sib txawv uas pom nyob rau lwm qhov kev tsim khoom, tshem tawm kev xav tau ntawm kev saib xyuas tus cwj pwm thiab tshem tawm qhov tsis raug. Qhov kev saib xyuas siv zog tshwj tsis siv tib neeg uas muaj rau die casting uses pab tso kev tsim khoom ntau dua, uas kev tsim khoom tuaj yeem mus ncig caug tsis tas mus, tsis tas muaj neeg saib xyuas ntau. Qhov kev tsim khoom nqa tawm no pab tso kev siv zog ntau dua thiab faib tus invest ntawm kev tsim khoom rau qhov tsim khoom ntau dua, tshem tawm tus nqi per-unit. Tom qab ntawd, die casting uses pab tso kev tsim khoom raws li kev xav tau los ntawm kev tso sijhawm lead tshaj taus thiab kev tso kev tsim khoom ntau dua raws li kev xav tau.

Kev tsim tawb nruj siv kev sau ua tawb nruj muaj qhov zoo tshaj plaws hauv yam ntxuav thiab kev tu siab tseg uas tsis muaj teeb meem, uas pab rau tus kws kho vaj tse ceev tsim cov khoom sib thooj uas muaj qhov txheej txheem zoo tshaj plaws, thaum kuj tseem nyob hauv qhov chaw tsim khoom uas muaj peev xeeb. Cov kev tsim tawb nruj nrog zog siab yog qhov tseemceeb rau kev tsim tawb nruj, uas tsim cov tawb nruj ntau thiab tsis muaj av, uas muaj qhov txheej txheem tshuaj xob uas feem ntau tshaj tshuaj txaus los ntawm lwm qhov kev tsim khoom. Qhov zog no, feem ntau nyob hauv qhov 10,000 mus rau 30,000 psi, txhawj xeeb tias txhua qhov chaw nyiag siab hauv tawb nruj tau raug sau kom ncig, thaum kuj tso siab tias tsis muaj cov av thiab lwm yam uas tuaj yeem ua rau cov khoom hlawv. Qhov kub sov tso tawm nrog qhov tseemceeb hauv kev tsim tawb nruj pab rau kev tsim cov microstructures me me, uas pab ntxaug qhov zog ntawm kev txhuam, kev tso tawm, thiab qhov nyiam hlau ntawm cov khoom tiav. Cov yam ntxuav zoo no ua rau kev tsim tawb nruj yog ib qhov kev xaiv zoo tshaj plaws rau kev siv hauv qhov chaw uas kev nyiam thiab kev ua haujlwm yog qhov tseemceeb. Qhov tu siab tseg uas muaj nyob hauv kev tsim tawb nruj pab rau tus kws kho vaj tse ceev ntxiv cov duab nrawm, ntau qhov thickness, thiab cov duab nrawm hauv chaw uas yuav tsis pom zoo lossis yuav muaj nuj nqi loj heev los ntawm kev saw, lossis lwm qhov kev tsim khoom. Cov chaw muaj qhov thickness li 0.5mm tuaj yeem raug sau tau hauv kev tsim tawb nruj, pab rau kev tsim khoom me me uas tseem muaj qhov nyiam hlau, thaum kuj tso siab tias tsis tas siv ntau yam ntxuav. Qhov tseemceeb ntawm kev sau cov chaw sov kub hauv chaw, cov chaw ntsuas, thiab cov rooj sib thooj hauv chaw tawm los ntawm kev tsim tawb nruj yuav tso siab tias tsis tas ua kev ua tom qab, thiab tso cai rau kev lag luam me me dua. Cov duab nrawm ntau qib thiab cov duab nrawm hauv chaw tuaj yeem raug tsim tau hauv kev tsim tawb nruj los ntawm kev siv cov chaw tsim khoom ncaj ncees uas muaj slides, cores, thiab cov cuab yeej collapsible. Qhov tu siab tseg no pab rau kev ruaj khov cov khoom ntau los ua ib qhov khoom sau, tso cai rau kev hloov pauv cov khoom, kev lag luam me me dua, thiab kev tso cai rau kev hloov pauv qhov chaw uas tuaj yeem hlawv hauv cov khoom tiav. Kev ntxig cov duab nrawm thiab cov duab nrawm tshawb nrhiav tuaj yeem raug ntxig tawm los ntawm kev tsim tawb nruj, tso siab tias tsis tas ua kev kho tom qab rau kev ntxig qhov zoo. Qhov tseemceeb uas muaj hauv kev tsim tawb nruj pab rau kev tsim cov chaw siv hauv qhov chaw, xws li sealing faces, bearing surfaces, thiab optical elements uas tshua tau qhov kev ua haujlwm tseemceeb tsis tas siv kev saw tom qab.

Qhov nyiaj txiag thiab qhov tseem ceeb ntawm kev siv die casting yog ua rau qhov kev tsim kho no yooj yim dua rau cov chaw tsim khoom uas muaj zog tshaj tiam ntawm kev tsim khoom zoo li cas thiab cheeb kam ntawm lub chaw tsim khoom. Qhov lag luam dhau los rau kev tsim khoom die casting feem ntau yog siv hauv kev tsim khoom ntau, uas tsim tau qhov nyiaj txiag per unit tso tseg me me thiab tso tseg dua thaum qhov ntau ntawm kev tsim khoom rov cuag. Kev tshwj tsis tau kev kho kho tom qab die casting yog ua kom tsis muaj kev lag luam, kev lag luam tsis tas siv, thiab kev lag luam ntxiv uas sib txuas nrog kev siv ntau zav, kev siv zav, thiab kev xav tau ntawm chaw tsim khoom. Qhov yooj yim hauv kev siv neeg hauv die casting yog los ntawm qhov kev tsim khoom siv zav ntau, uas ib tug neeg tsim khoom tuaj yeem saib xyuas ntau tus zav tsim khoom ib txwm, uas pab kom nyiaj siv neeg per daim me me dua. Qhov yooj yim hauv kev siv khoom siv die casting tuaj li 95% lossis ntau dua, vim qhov kev tsim khoom closed-die tsim tau qhov khoom tsis zoo me me heev kom rau kev tsim khoom siv kev tshuaj tshem. Qhov yooj yim no tuaj li qhov nyiaj txiag ntau, tshuav tias thaum siv alloys ntau nyiaj lossis thaum qhov nyiaj khoom siv dhau plua pluag. Qhov kev siv khoom zoo dua hauv die casting pab kom nyiaj txiag dua, vim tias cov runners, sprues, thiab cov daim tsis raug tuaj yeem rov them ntau thiab rov siv ntau tsis muaj kev puav tswj. Qhov yooj yim hauv kev siv zog hauv die casting zoo dua kev tsim khoom lwm yam, vim qhov kev tsim khoom ntev thiab kev siv khoom yooj yim pab kom tsis siv zog ntau per daim uas tsim tau. Die casting siv systems rov qab zog uas rov qab heat waste los ntawm kev sov thiab rov them nws mus rau kev sov, uas pab kom yooj yim dua hauv kev siv zog. Qhov tseem ceeb hauv die casting tsis yog tsuas yog nyob rau kev siv zog thiab khoom zoo dua, tab sis kuj muaj kev siv transport tsawg dua vim kev tsim khoom tuaj yeem nyob deb npaum li qhov chaw xa khoom. Cov khoom me me uas tsim los ntawm die casting pab kom siv fuel zoo dua hauv kev siv transport, uas tsim tau qhov tseem ceeb hauv environment thaj yam txog lub teebchaws. Qhov siv dej hauv die casting yog tsawg dua kev tsim khoom xwm yeem siv coolant systems ntau lossis chemical treatments, thiab cov chaw tsim khoom siv systems sov tso tseg uas tshem tej dej tsis zoo. Qhov ntev thiab zoo siab ntawm cov khoom tsim los ntawm die casting yog ua kom tsis tas siv dua thiab ntev dua, uas pab kom tseem ceeb dua los ntawm kev tsis siv khoom ntau thaj yam txog lub teebchaws.
