Thaum koj hnov 'lub ntiajteb txawj nqus casting', ntau tus neeg, txawm tias qee tus hauv kev lag luam, duab ib qho yooj yim ncuav. Tsuas yog qaij lub ladle thiab cia lub ntiajteb txawj nqus ua haujlwm, txoj cai? Qhov ntawd yog qhov biggest oversimplification. Nws tsis yog hais txog kev ua thawj zaug; nws yog hais txog kev tswj. Kev kos duab tiag tiag - thiab mob taub hau - nyob rau hauv kev tswj cov thermal dynamics thiab pwm tsim kom tau lub suab nrov tsis muaj kev pab cuam. Kuv tau pom ntau txoj haujlwm maj nrawm uas cov hlau zoo li zoo rau saum npoo, tab sis cov qauv sab hauv yog qhov tsis sib haum, ua rau tsis ua haujlwm hauv kab. Nws yog tus txheej txheem uas xav tau kev ua siab ntev thiab kev nkag siab tob txog seb koj qhov tshwj xeeb alloy coj li cas thaum nws txias tsis muaj dab tsi tab sis nws qhov hnyav.
Lub hauv paus ntsiab lus thiab qhov twg nws haum
Ntawm nws lub siab, gravity casting yog txheej txheem pwm mus tas li. Koj tau txais cov pwm tuaj yeem siv tau, feem ntau yog hlau lossis hlau, thiab koj cia siab rau lub zog gravitational los sau cov kab noj hniav. Tsis muaj twj, tsis muaj siab. Qhov no teeb nws sib nrug los ntawm high-pressure tuag casting tam sim ntawd. Kev sau qeeb qeeb, ntau laminar yog tias koj tau txais nws txoj cai. Qhov ntawd yog qhov tseem ceeb rau qee yam khoom siv. Piv txwv li, nrog qee cov aluminium alloys los yog qee cov tooj liab-raws li cov khoom, cov turbulent filling tuaj yeem ntxiab oxides thiab roj, tsim cov chaw tsis muaj zog. Lub ntiajteb txawj nqus pouring, thaum lub rooj vag system tsim kom raug, tuaj yeem txo qhov ntawd.
Tab sis nws tsis yog ib qho loj-haum-tag nrho cov kev daws teeb meem. Nws ci qhov twg? Rau nruab nrab-ntim khiav ntawm qhov chaw uas xav tau cov cuab yeej zoo dua li qhov koj feem ntau tau txais los ntawm kev kub siab tuag casting. Xav txog cov khoom siv tsheb xws li cov caj npab ncua kev kawm, qee lub cav cav, lossis cov vaj tsev loj dua. Lub zog qeeb qeeb nyob rau hauv lub ntiajteb txawj nqus tuaj yeem ua rau lub denser, tsawg ntxeem tau. Txawm li cas los xij, kev lag luam tawm yog lub sijhawm voj voog thiab tus nqi nce siab ntawm qhov zoo, ruaj khov pwm. Nws yog ib qho kev suav: puas yog qhov kev ncaj ncees zoo tshaj plaws ntawm qhov ua kom pom tseeb tus nqi qis dua piv rau kev tuag casting?
Kuv nco ntsoov ib qhov project rau lub twj tso kua mis vaj tse, ib tug ncaj complex duab nrog txawv phab ntsa thicknesses. Tus neeg siv khoom pib xav tuag casting kom ceev. Peb sib cav rau gravity casting nyob rau hauv ib tug semi-steel pwm. Kev sib cav yog hais txog kev ua neej ntev. Tuag casting yuav tau sai dua, tab sis lub peev xwm rau micro-porosity nyob rau hauv cov seem thicker yog ib qho kev pheej hmoo rau lub nkoj siab. Peb khiav prototypes ob txoj kev. Lub ntiajteb txawj nqus-cam khwb cia ib feem, tom qab machining, pom kev ncaj ncees nyob rau hauv kev sim siab. Tus tuag-casting muaj ib tug ntau dua seem npaum li cas los ntawm to. Qhov kev ua kom qeeb qeeb thiab kev taw qhia solidification ua qhov txawv.
Dab Ntxwg Nyoog hauv Cov Lus Qhia: Pwm Tsim thiab Tswj Thermal
Qhov no yog qhov uas 'tes ntawm tus kws ua haujlwm' tuaj, txawm hnub no. Cov pwm tsim rau lub ntiajteb txawj nqus casting yog txhua yam. Lub rooj vag - yuav ua li cas cov hlau nkag mus rau hauv kab noj hniav - tsis yog ib qho channel xwb; Nws yog lub thermal thiab hydraulic tswj system. Koj yuav tsum tau tsim nws kom txo qis kev kub ntxhov, tab sis kuj yuav tsum xyuas kom meej cov ntu tuab yog noj kom zoo raws li cov hlau shrinks. Kuv tau siv sij hawm nrog khiav simulation software, tsuas yog yuav tsum tau tweak lub pwm tiag tiag vim hais tias cov software cov khoom qauv tsis zoo tag nrho rau peb cov batch ntawm alloy.
Tom qab ntawd muaj pwm kub. Qhov no yog kev sib ntaus sib tua tas li. txias dhau, thiab cov hlau yuav txias sai heev, ua rau cov mistrus lossis txias kaw. Kub dhau heev lawm, thiab koj yuav raug soldering (lub casting sticking rau pwm), qeeb voj voog, thiab ib tug grainy, tsis muaj zog qauv. Koj tsim lub suab nrov. Txau, ncuav, txias, eject, tsuag dua. Hom lub tsho tiv no uas koj siv - cov tshuaj tsuag ceramics - cuam tshuam rau kev rho tawm thiab tso tawm. Tau txais qhov kev sib raug zoo yog kev kos duab ntau dua li kev tshawb fawb qee zaum. Ib lub tuam txhab uas muaj qhov down pat, zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), leverages xyoo lawm ntawm no tacit paub. Koj tuaj yeem pom nws hauv qhov sib xws ntawm lawv cov castings. Lawv tau nyob ntawm no tau 30 xyoo (https://www.tsingtaocnc.com), thiab qhov kev paub no txhais ncaj qha rau hauv lawv li cas lawv tswj pwm thermal cycles thoob plaws cov ntaub ntawv sib txawv, los ntawm cam khwb cia hlau mus rau npib tsib xee alloys.
Ib qho kev ua tsis tiav uas qhia kuv ntau heev yog nrog ib qho yooj yim-saib caj npab hauv cov hlau nplaum. Cov pwm tsim saib cov ntawv nyeem. Tab sis peb khaws cia tau txais shrinkage porosity nyob rau hauv ib qho tseem ceeb load-bearing hub. Peb sim nce qhov kub thiab txias, ntxiv risers ... tsis muaj dab tsi ua haujlwm. Thaum kawg, ib tus neeg tsim khoom qub tau hais tias peb ntxig ib qho me me, siab-conductivity tooj liab chill pin rau hauv pwm phab ntsa ntawm qhov teeb meem. Nws tsis yog nyob rau hauv ib phau ntawv peb muaj. Nws yuam kom qhov chaw tshwj xeeb kom khov ua ntej, coj cov shrinkage rov qab mus rau lub riser. Teeb meem daws tau. Nws yog ib zaj lus qhia phem nyob rau hauv kev tswj xyuas thermal.
Kev xaiv khoom thiab kev txwv
Lub ntiajteb txawj nqus casting yog ntau yam, tab sis tsis infinitely li. Aluminium thiab magnesium alloys muaj ntau, feem ntau rau lawv cov fluidity zoo. Tej tooj dag thiab bronzes nchuav zoo nkauj. cam khwb cia hlau thiab hlau kuj tseem ua los ntawm kev nqus cov txheej txheem, txawm hais tias feem ntau hauv cov xuab zeb pwm ntau dua li cov pwm hlau tas mus li vim lawv qhov kub thiab txias, uas yuav rhuav tshem cov pwm hlau sai. Thaum koj saib tus kws tshaj lij zoo li QSY, lawv cov kev txawj ntse nthuav tawm lub plhaub pwm thiab peev casting nrog rau lawv cov peev txheej machining. Qhov no yog qhia. Lub ntiajteb txawj nqus casting hauv cov pwm mus tas li yog ib qho cuab yeej. Rau super high-temperature alloys los yog incredibly complex geometry, lawv yuav hloov mus rau peev casting. Qhov kev xaiv yeej ib txwm tsav los ntawm cov khoom siv tus cwj pwm thiab qhov kawg ntawm qhov yuav tsum tau ua.
Qhov kev txwv nrog pwm mus tas li gravity casting yog tiag tiag txog cov khoom pwm qhov kam rau ua kom sov. Koj tsis tas yuav nchuav molten stainless hlau ntawm 1500 ° C + rau hauv cov pwm hlau ntau zaus - nws yuav warp thiab degrade sai. Yog li ntawd, rau cov khoom uas muaj melting point tiag tiag, koj pom kev txav mus rau ib-tawm ceramic plhaub pwm (kev nqis peev) lossis xuab zeb pwm, qhov twg cov pwm tau txi. Lub hauv paus ntsiab lus 'lub ntiajteb txawj nqus' tseem tuaj yeem siv rau hauv lub ncuav, tab sis cov pwm pwm txawv. Qhov no yog ib qho tseem ceeb sib txawv feem ntau glossed tshaj.
Peb tau sim ib zaug nrog ib feem ntawm cobalt-based alloy. Cov neeg siv khoom xav tau qhov hnav tsis kam tab sis cia siab rau pwm mus tas li rau tus nqi. Qhov kev sim yog kev puas tsuaj. Txawm tias muaj cov txheej txheem ceramics siab heev, cov thermal shock ntawm cov pwm hlau yog kev puas tsuaj tom qab ob peb nchuav. Peb yuav tsum rov qab mus thiab pom zoo kom muaj kev nqis peev casting txoj kev, uas lawv siv thaum kawg. Koj yuav tsum paub cov ciam teb ntawm cov txheej txheem.
Kev sib xyaw ua ke nrog Machining: Seamless Flow
Yuav luag tsis muaj lub ntiajteb txawj nqus-cam khwb cia yog tiav li-cam khwb cia. Koj yuav tsum tau tshuab lub ntsej muag tseem ceeb, tho qhov, ntxiv cov xov. Qhov no yog qhov uas cov txheej txheem casting yuav tsum tau tsim nrog machining hauv siab. Kev sib haum xeeb yog huab tais rau tus kws kho tshuab. Yog tias koj cov txheej txheem casting yields variations nyob rau hauv phab ntsa thickness los yog ib qho nyuaj me ntsis los ntawm uneven txias txias, koj yuav kub hnyiab tau los ntawm cov cuab yeej thiab tau txais qhov seem seem. Kev khiav zoo gravity casting cov txheej txheem yuav tsum tsim kom muaj kev kwv yees, cov khoom lag luam tsis sib xws.
Qhov no yog qhov zoo ntawm kev ua haujlwm vertically integrated. Ib lub tuam txhab uas ua ob qho tib si casting thiab CNC machining nyob rau hauv ib lub ru tsev, zoo li QSY, muaj ib lub voj voog tawm tswv yim uas muaj nuj nqis. Pab neeg machining qhia lub foundry yog tias ib lub lug ib txwm nyuaj dhau, lossis yog tias lub ntsej muag datum muaj ntau qhov sib txawv. Lub foundry tuaj yeem kho cov pwm txias los yog lub ncuav sib lawv liag. Nws yog qhov kev sib koom ua ke uas hloov qhov zoo casting mus rau hauv ib qho kev txhim khu kev qha, precision tivthaiv. Lawv lub website (https://www.tsingtaocnc.com) qhia txog qhov kev sib koom ua ke - nws tsis yog ib daim ntawv teev cov kev pabcuam xwb; nws yog ib qho kev piav qhia ntawm kev sib txuas ntawm kev tsim khoom txaus.
Kuv nco qab ib pawg ntawm txhuas vaj tse nyob qhov twg cov machining yield dheev poob. Cov machinists tau yws txog cov cuab yeej ceev ceev ntawm ib qho chaw sab hauv. Lub casting ntsia zoo. Peb taug qab nws rov qab mus rau qhov kev hloov pauv ntawm lub tsho tiv no txau cov qauv. Nws tau ua rau thaj tsam ntawm cov pwm khiav me ntsis txias dua, tsim kom muaj qhov zoo dua, nyuaj microstructure ntawm lub ntsej muag ntawm lub casting. Kev kho me ntsis rau cov tshuaj tsuag neeg hlau txoj kev kho nws. Yog tias tsis muaj pawg casting thiab machining tham txhua hnub, qhov teeb meem ntawd tuaj yeem rub rau ntau lub lis piam.
Common Pitfalls thiab yuav ua li cas kom zam tau lawv
Dhau ntawm cov khoom siv, muaj qhov ua tau zoo. Ib qho yog over-complexing pwm kom txo machining. Qee lub sij hawm nws yog pheej yig dua los nrum cov duab yooj yim thiab tshuab ntau dua hlau ntau dua li tsim thiab tswj cov pwm tsis yooj yim nrog cov cores tsis yooj yim. Lwm qhov yog tsis saib xyuas lub sijhawm kho pwm. Cracks, yaig nyob rau hauv lub rooj vag, built-up tuag lub tsho tiv no - cov no maj mam degrade zoo. Koj xav tau kev tswj hwm nruj rau kev tshuaj xyuas thiab kho dua tshiab.
Qhov loj tshaj pitfall, nyob rau hauv kuv saib, yog kho gravity casting raws li qhov kev xaiv 'tsawg-tech' thiab yog li kev nqis peev hauv cov txheej txheem tswj. Saib xyuas qhov ntsuas kub kom meej, tswj pwm qhov kub thiab txias, siv cov khoom zoo, cov khoom siv zoo ib yam - cov no tsis yog qhov chaw txiav cov fab. Cov txheej txheem nqus tau zam rau qee txoj hauv kev, tab sis nws rau txim rau qhov tsis sib xws hnyav. Cov tsis xws luag yuav tsis tshwm sim kom txog rau thaum kev sim zaum kawg lossis, phem dua, hauv daim teb.
Thaum kawg, kev sib txuas lus nrog tus tsim qauv yog qhov tseem ceeb. Koj feem ntau yuav tsum tau qhia lawv txog cov kaum sab xis, qhov zoo tshaj plaws ntawm phab ntsa thickness hloov, thiab qhov tseem ceeb ntawm cov seem tsis sib xws rau cov txheej txheem no. Ib tug tsim zoo meej rau forging los yog fabrication tej zaum yuav npau suav phem rau nrum soundly. Kev koom tes thaum ntxov yog txoj hauv kev zoo tshaj plaws kom tsis txhob muaj qhov teeb meem. Nws yog hais txog kev teeb tsa qhov kev cia siab tiag tiag raws li lub cev ntawm cov hlau ntws thiab ua kom ruaj khov nyob rau hauv nws tus kheej qhov hnyav - lub tswv yim yooj yim dag uas, hauv kev xyaum, yuav tsum muaj kev paub tob rau kev paub.
