Automobile Casting Txheej Txheem Kev Paub thiab Kev Txhim Kho Nruab Nrab Technology

Kwv yees li 15% mus rau 20% ntawm qhov pib qhov khoom yog castings uas ua los ntawm ntau txoj kev ua yeeb yam. Cov yeeb yaj kiab no yog qhov tseem ceeb ntawm lub zog thiab qhov tseem ceeb ntawm cov qauv. Tam sim no, Tebchaws Europe thiab hauv Teb Chaws Asmeskas kev tsim tsheb tsim tau tsim tau lub teb chaws, kev tsim cov khoom siv cuab yeej technology zoo tshaj plaws, cov khoom muag zoo, kev ua haujlwm siab zoo, kev ua kom muaj paug thaj tsam. Casting cov ntaub ntawv nyoos thiab lwm yam khoom tau tsim tau ua tiav thiab kev tsim qauv, txhua tus txheej txheem tsim muaj tiav rau kev sib tsoo, kev siv tsheb thiab kev txawj ntse. Cov tebchaws no feem ntau siv cov cuab yeej siv technology los txhim kho cov txheej txheem kev tsim qauv, pov cov nqi khwv yees li ntawm 2% mus rau 5%, thiab tau tsim muaj ntau qhov kev pabcuam thiab kev siv technology. Nyob rau hauv sib piv, txawm tias Tuam Tshoj lub tsheb castings loj tshaj, tab sis feem ntau ntawm lawv yog cov tsawg-ntxiv cov nqi thiab tsawg technical cov ntsiab lus, tus qauv yog cov yooj yim dub castings, thiab qhov sib txawv ntawm txawv teb chaws. Tsab xov xwm no tsuas yog tham txog txoj kev loj hlob ntawm kev tsav tsheb thiab kev siv tshuab hauv tsheb los ntawm kev xav tau ntawm kev siv hluav taws xob txuag thiab kev tiv thaiv ib puag ncig.

1. Cov kev coj ua ntawm txoj kev tsim cov tsheb ciav hlau

1.1 kev tsim qauv ntawm tsheb ciav hlau

Nrog rau kev siv hluav taws xob txuag thiab txo cov nqi ntawm cov khoom siv yuav tsum ua kom nce ntxiv, ua kom tiav ntawm qhov zoo ntawm kev pov thawj, qhov qub stamping, vuam, forging thiab casting tsim ntau qhov chaw, los ntawm kev tsim qauv thiab kev ua zoo, Ua Tsuav Ua Tau, yuav pab txo qhov hnyav ntawm qhov chaw thiab txo qhov kev ua tsis tiav ntawm txoj kev, kom ua tiav qhov nyhav ntawm qhov chaw thiab kev ua tau zoo.

Txoj kev loj hlob ntawm kev sib raug zoo ntawm lub tsheb sib txuas yog pom tseeb hauv kev loj hlob ntawm nonferrous alloy castings. Thiaj li yuav siv tag nrho kev siv txoj kev pov thawj los ua kom tau cov yam ntxwv ntawm cov khoom siv ntawm cov txheej txheem ua kom muaj zog, muaj kev sib txuas ntawm cov qhov rooj, rooj pob zeb, pob zeb kab hlau, qhov loj me yog loj tshaj qhov Casting ntau lawm, xav tau 4 000 ~ 5 000 t lossis ntau dua tonnage tuag casting tshuab rau ntau lawm.

1.2 Qhov nyhav ntawm cov tsheb ciav hlau

Los xyuas kom lub zog thiab kev nyab xeeb ntawm lub tsheb nyob rau hauv qhov chaw ntawm lub tsheb kom ntau li ntau tau kom txo tau qhov zoo ntawm kev npaj, ua kom tau qhov sib, ua kom qhov tsav tsheb muaj zog, txo cov roj siv thiab txo cov pa pa phem. Qhov zoo ntawm lub tsheb yog txo los ntawm 100 kg thiab roj noj ib 100 km thiaj li raug txo los ntawm 0.3 mus rau 0.6 L. Yog tias lub tsheb qhov hnyav txo 10%, qhov roj efficiency yuav nce tau nce li 6% mus rau 8%. Nrog rau kev tiv thaiv ib puag ncig kev tiv thaiv thiab kev txuag hluav taws xob, qhov nyhav ntawm lub tsheb tau dhau los ua lub ntiaj teb txoj kev loj hlob kev tsheb, qhov nyhav ntawm cov khoom pov thawj tsheb tau ua ib qho tseem ceeb ntawm txoj kev loj hlob ntawm cov tsheb castings.

2. Txoj kev loj hlob ntawm kev siv cov cuab yeej cuab tam tsheb

Cov cuab yeej siv ntau hauv thin - walled complex qauv castings

Nrog txoj kev lag luam hauv tsheb thiab kev thov kom muaj kev txuag hluav taws xob thiab txo qis qis, qhov nyhav ntawm qhov khoom seem yog qhov ntau dua. Los ntawm kev tsim cov khoom tsim, nws yog ib qho tseem ceeb ntawm txoj kev loj hlob ntawm cav thaiv. FAW Casting Co., Ltd. rau lub FAW Volkswagen ntau lawm cam khwb cia hlau kheej, piv txwv li, thaum ntxov ntawm 06A lub tog raj kheej phab ntsa thickness 4.5 hli ± 1.5 hli, EA111 lub tog raj kheej phab ntsa thickness 4 hli ± 1 hli, qhov ntau lawm ntau lawm EA888Evo2 lub tog raj kheej phab ntsa thickness 3.5 hli ± 0.8 hli, tom ntej no cim EA888Gen.3 lub tog raj kheej khoom qauv ntau dua, phab ntsa thickness ntawm xwb 3 hli ± 0.5 hli, yog thinnest grey cam khwb cia hlau kheej kheej. Nyob rau hauv qhov ntau lawm, muaj qee qhov teeb meem xws li cov tub ntxhais uas tawg, kev tshav mis thiab phab ntsa thickness fluctuating. Txawm li cas los xij, los ntawm kev tswj cov tub ntxhais cov xuab zeb thiab cov xuab zeb, Tiam sis tsis tuaj yeem ua raws li lub EA888Gen.3 lub tog raj kheej uas yuav tsum tau ua, yuav tsum yog siv tag nrho cov txheej txheem tseem ceeb.

2.2 Aluminium-magnesium alloy loj-txheej yam khoom siv tshuab

Nrog rau kev thov kom muaj kev txuag hluav taws xob, kev tiv thaiv ib puag ncig thiab kev txo nqi, txhuas magnesium alloy loj-teev yam ntxwv casting tau los ua ib qho tseem ceeb ntawm txoj kev loj hlob, thiab nws cov cuab yeej siv tshuab tau dhau los ua qhov kev loj hlob tam sim no. Tam sim no, lub ntsiab tsim tshuab ntawm aluminium-magnesium alloy loj-teev yam ntxwv yog high-pressure casting, extrusion casting thiab low-pressure casting. Raws li qhov kev siv high-pressure casting efficiency, cov khoom zoo tau ua cov txheej txheem tseem ceeb, nws txoj kev tsim technology tsim tsom rau txoj kev lag luam loj yog yooj yim rau curl, casting yooj yim rau cov pores, tsis tau kub cov teeb meem kev kho mob.

2.3 Casting Precision Casting Technology

Feem ntau raug xa mus rau qhov tseeb casting ntawm automotive casting tsuas yog hais txog cov tshem tawm pwm thiab peev casting technology. Nrog rau txoj kev tsim kho tsheb, ua qhov kev txiav txim siab yog ib hom kev sib tw ua qauv. Castings uas ua los ntawm hom kev ua no yuav siv ncaj qha tsis txiav los yog txiav. Nrog txoj kev txhim kho casting loj npaum li cas, casting precision forming technology tau tsim sai heev nyob rau hauv xyoo tsis ntev los no, thiab ntau txoj kev tshiab casting tau tsim xws li precision sand casting, Lost Casting Casting, Controlled Pressure Casting thiab Pressure Casting. Lub Cosworth casting txujci tau tsim los ntawm UK siv kev sib xyaw ntawm cov zirconium xuab zeb thiab tswj los ntawm ib qho twj tso kua hauv electromagnetic. Nws tau zoo siv rau huab hwm coj ntau ntawm aluminium alloy thooj voos kheej kheej thiab tau tshwm sim nyob rau hauv ntau txoj kev ua muaj xws li tsis tshua muaj siab casting siv electromagnetic Pump casting thiab lwm yam dab. Kev siv hom kev ua tus casting tuaj yeem tsim phab ntsa thickness ntawm 3.5 ~ 4.0 hli txhuas alloy lub tog raj kheej, tam sim no precision sand casting sawv cev ntawm tus txheej txheem.

Nyob rau hauv kev lag luam high-pressure casting tsim los ntawm lub tshuab nqus tsev, oxygenated die-casting, semi-solid hlau rheological los yog thixotropic tuag-casting, tsim los tshem tawm cov teeb meem nrawm, txhim kho nyob zoo thiab nthuav cov voj voos ntawm cov ntaub ntawv tuag casting. Nyob rau hauv cov txheej txheem ntawm extrusion casting, lub yaj yog ntim thiab solidified nyob rau hauv siab, thiab muaj qhov zoo ntawm tus, tsis muaj hlau splashing, tsis muaj hlau oxidation hlau dua, lub zog txuag, haujlwm zoo thiab tsis raug ntawm casting qhov. High-performance aluminium alloy casting txoj kev loj hlob thiab daim ntawv thov ntawm ntau hom kev siv.

Kev nruam kev loj hlob ntawm lub tsheb yuav tsum kom muaj kev sib tw ua kom zoo tshaj plaws, kev ua haujlwm zoo, ze ntawm cov qauv zoo, ntau hom, tsawg noj, tsis tshua muaj kev taw qhia. Raws li lub tsheb txog 15% mus rau 20% ntawm qhov chaw yog castings. Qhov no yuav tsum muaj kev lag luam casting mus siv ntau yam ntawm cov tshiab technologies, cov ntaub ntawv tshiab los txhim kho tag nrho theem ntawm casting. Casting precision casting tshuab tuaj yeem ua kom tau raws li cov cai ntawm cov ntawv pov thawj, thiab nws cov ntawv yuav tau them rau qhov sib txawv casting ntawm automotive castings.

Yuav kom ua tau raws li qhov kev xav tau ntxiv rau cov cai, cov tsheb khiav ntawm lub cev nyhav. Txo tsav tsheb li ntawm 10%, kev siv roj yuav txo tau 5.5%, roj economy yuav nce ntxiv ntawm 3% mus 5%, thaum txo cov emissions txog li 10%. Daim ntawv thov ntawm aluminium thiab magnesium thiab lwm yam nonferrous alloy castings, txoj kev loj hlob ntawm cov txheej txheem loj ntawm cov ntaub ntawv pov thawj thiab nws daim ntawv thov kev nplua nuj casting molding tshuab yog ua kom cuag txoj kev loj los txo qhov nyhav ntawm cov tsheb castings. Thiab yog li no nws yuav siv nws cov cuab yeej siv los ntawm kev siv cov cuab yeej cuab tam, kev siv cuab yeej automation, xws li ntau ntau ntawm kev txhais tau tias kom ua tiav txoj kev txhim kho thiab kev tsim tsheb ntawm cov tsheb sib txuas lus kom tau raws li cov kev xav tau ntawm cov kev lag luam niaj hnub.
