Thaum koj pib nrhiav lub ntiajteb txawj nqus tuag casting tsum, thawj nthwv dej ntawm cov ntaub ntawv feem ntau yog ib phab ntsa ntawm tib yam. Txhua lub vev xaib hais txog qhov zoo, qhov tseeb, thiab ntau xyoo ntawm kev paub. Nws yog ib qho yooj yim kom tau txais lub tswv yim tias cov txheej txheem - ncuav molten hlau mus rau hauv lub reusable steel pwm nyob rau hauv lub ntiajteb txawj nqus - yog ncaj nraim thiab hais tias tej foundry nrog cov khoom yuav xa. Qhov ntawd yog thawj ntxiab. Qhov sib txawv tiag tiag tsis yog lub tshuab; nws yog qhov sib sau ua ke, feem ntau tsis hais, kev paub txog kev tswj xyuas thermal, kev coj tus cwj pwm alloy, thiab cov cuab yeej tsim uas cais ib feem uas ua haujlwm ntawm ib feem uas ua tau zoo. Kuv tau pom ntau qhov chaw nres tsheb vim tias tus neeg yuav khoom tau tsom rau ntawm tus nqi tsev thiab lub sijhawm ua haujlwm, kho cov txheej txheem raws li cov khoom lag luam. Tsis yog.
Lub hauv paus misconception: Nws tsuas yog Pwm
Cov neeg xav tias lub ntiajteb txawj nqus tuag casting yog qhov yooj yim vim lub tswvyim yog. Koj muaj hlau pwm, koj ncuav, koj txias, koj eject. Tab sis dab ntxwg nyoog yog nyob rau hauv lub thermal dynamics. Koj yuav ua li cas tswj cov cua sov hauv qhov tuag kom tsis txhob ntxov ntxov solidification nyob rau hauv nyias seem los yog porosity nyob rau hauv tuab bosses? Qhov no tsis daws los ntawm phau ntawv; nws tau daws los ntawm tus qauv tsim thiab foundry engineer uas tau pom ib puas variations. Kuv nco qab txog qhov project rau marine hardware tivthaiv hauv aluminium-silicon alloy. Cov qauv thawj zaug los ntawm tus neeg muag khoom tshiab tau kaw qhov txias txias ntawm lub ntsej muag tseem ceeb. Lawv txoj kev daws teeb meem yog kom nce qhov kub thiab txias, uas tsuas yog tsim teeb meem shrinkage nyob rau lwm qhov. Qhov kev txhim kho tiag tiag, uas peb tau tsaws rau tom qab ob qhov ua tsis tiav, yog kev sib xyaw ua ke ntawm kev kho lub rooj vag geometry thiab ntxiv cov cua txias tshwj xeeb rau qhov tuag. Tus neeg muag khoom daim ntawv qhia tau hais tias lawv muaj kev simulation siab tshaj plaws, tab sis cov ntawv thov siv tau ua lag luam.
Qhov no yog qhov uas tus neeg muag khoom qhov tseeb pedigree qhia. Ib lub tuam txhab zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) hais txog 30 xyoo hauv casting thiab machining yog lub teeb liab, tab sis koj yuav tsum khawb. Peb caug xyoo txhais tau hais tias lawv tau zoo li yuav dhau los ntawm kev lag luam poob qis, cov khoom siv tsis txaus, thiab cov neeg siv khoom xav tau. Lub koom haum nco ntawd yog ib qho cuab yeej txo kev pheej hmoo. Tej zaum lawv tau pom dab tsi tshwm sim thaum koj khiav ib qib ntawm cov hlau hlau hauv lub ntiajteb txawj nqus tuag pwm tsim rau grey hlau. Ntawd cov ntaub ntawv siv tau yog qhov tseem ceeb.
Kev xaiv cov khoom siv yog lwm txheej. Lub ntiajteb txawj nqus tuag casting tsis yog rau txhuas. Thaum txhuas thiab nws cov alloys muaj ntau, cov txheej txheem kuj tseem siv rau magnesium, tooj liab-raws li alloys, thiab txawm tias qee cov cam khwb cia hlau. Ib tus neeg muag khoom nrog cov khoom siv nqaim kom pom tseeb yuav sim yuam kom haum rau hauv cov txheej txheem nws tsis zoo rau. QSY cov kws tshaj lij hauv cov hlau tsis muaj steel thiab cov alloys tshwj xeeb zoo li cov nickel-raws li cov lus qhia kom paub txog cov ntsiab lus siab melting point, cov ntaub ntawv nyuaj. Qhov no txhais tau hais tias lawv txoj hauv kev rau kev tuag tsim thiab kev tswj xyuas thermal yog tsim rau qhov dav, xav tau ntau yam ntawm cov xwm txheej tshaj li lub khw uas tsuas yog A356 txhuas. Nws yog qib sib txawv ntawm cov tshuab hluav taws xob, kev tshawb fawb txog kev tuag, thiab kev tswj cov txheej txheem.
Qhov twg Machining Integration tsis xaiv tau
Ntawm no yog ib zaj lus qhia nyuaj uas khwv tau: tsis txhob cais tus neeg muab khoom pov tseg los ntawm cov khoom siv machining rau qhov tseem ceeb-tolerance. Kev sib koom tes ntawm casting thiab CNC machining yog ib qho av fertile rau ntiv tes taw. Yog hais tias qhov zoo li-cam khwb cia muaj ib tug me ntsis distortion los yog ib tug tseem ceeb datum lub ntsej muag yog tsis optimally nyob, tus machinist yog sab laug kom them, feem ntau noj rau hauv cov ntaub ntawv spec los yog tsim cov phab ntsa tuab. Kuv tau nyob rau hauv cov rooj sib tham uas tus caster liam tus kws kho qhov teeb meem, thiab tus kws kho tshuab ua rau lub caster tsis sib xws. Nws yog nkim sij hawm thiab nyiaj txiag.
Ib tug vertically integrated tsum, ib tug uas tuav ob lub gravity tuag casting thiab tom qab CNC machining nyob rau hauv ib lub ru tsev, tshem tawm qhov no. Lawv pab pawg machining muab cov lus qhia ncaj qha rau lawv pawg neeg tsim khoom. Lawv tuaj yeem tsim cov casting nrog machining fixtures hauv siab los ntawm hnub ib. Saib ntawm QSY tus qauv - qhov twg lawv qhia meej meej ob qho tib si casting (plhaub, peev) thiab CNC machining raws li cov kev pabcuam tseem ceeb - qhov kev sib raug zoo no muaj nyob hauv. Rau lub ntiajteb txawj nqus tuag cam khwb cia ib feem, qhov no txhais tau hais tias lawv muaj peev xwm muab tswv yim tso cua ntsawj ntshab, kho phab ntsa thickness, thiab nrhiav parting kab tsis yog rau casting efficiency, tab sis kom ntseeg tau tias ib feem ntawm lub pob zeb-khoom nyob rau hauv ib tug CNC vise tsib kauj ruam tom qab. Kev txuag nqi thiab kev ruaj ntseg zoo los ntawm qhov no feem ntau underestimated nyob rau hauv RFQ sib piv.
Peb muaj ib qhov project gearbox vaj tsev nyob qhov twg thawj tus neeg xa khoom xa khoom zoo nkauj uas dhau tag nrho cov kev kuaj xyuas. Tab sis thaum lub sij hawm machining, lub nyias-walled flange yuav chatter vim hais tias lub sab hauv ribbing, tsim rau casting stability, tsim ib tug tsis sib haum xeeb thaum txiav. Ib tus neeg muab khoom siv sib xyaw ua ke yuav tau ntes tau qhov ntawd nyob rau hauv theem prototyping. Peb tau hloov mus rau ib tus khub nrog ob lub peev xwm, thiab lawv rov tsim cov qauv tav nrog cov tswv yim los ntawm lawv cov hlau lead. Qhov thib ob-round qauv machined zoo li butter. Zaj lus qhia tau meej meej: cov txheej txheem yog qhov txuas ntxiv, tsis yog cov kev pabcuam siled.
