Txoj kev loj hlob sai ntawm Tuam Tshoj txoj kev lag luam tsheb tau txhawb txoj kev loj hlob ntawm kev lag luam tuag-casting.Ningbo Beilun nyiam lub koob npe nrov ntawm "lub nroog ntawm tuag casting pwm hauv Suav teb".Ntxiv rau kev muab cov khoom siv hauv tsev Volkswagen, FAW, Chang'an, Chery, Geely, Great Wall, Chunlan, Midea thiab lwm yam lag luam, nws cov khoom kuj muab pwm rau Mercedes Benz, Volkswagen, Audi, Siemens, Ford, General Motors, Mazda thiab lwm yam. ntiaj teb nto moo lag luam.Kev tsim thiab tsim qib, muaj peev xwm ntau lawm thiab kev lag luam kev lag luam ceev ntawm tuag casting pwm yog nyob rau hauv txoj hauj lwm ua nyob rau hauv Suav teb.
Xyoo 2007, tus nqi tsim khoom ntawm Beilun pwm mus txog 2.8 billion yuan, nrog rau kev xa tawm mus txog 300 lab yuan.Cov nyiaj tau los ntawm cov khoom tuag-casting yog 2.6 billion yuan, nrog rau kev xa tawm mus txog 420 lab yuan.
1. Txoj hauj lwm ntawm Beilun tuag-casting pwm nyob rau hauv lub teb chaws
Beilun pwm kev lag luam pib nyob rau hauv 1960s thiab tsim sai heev nyob rau hauv 1990s, tsom rau tuag-casting pwm.Tom qab ntau tshaj 20 xyoo ntawm txoj kev loj hlob, nws tau tsim ib tug xov tooj ntawm zoo lag luam nrog cov yam ntxwv txawv, thiab tsim xya lub nroog high-tech tuam txhab thiab ob lub xeev Enterprise engineering engineering technology chaw nyob rau hauv lub pwm kev lag luam.Muaj 34 lub tuam txhab tuag-casting pwm nrog cov pwm tso tawm tus nqi ntau dua 10 lab yuan.
1.1 Qhov tseem ceeb tuag-casting pwm lag luam
Txij Lub Ib Hlis 1, 2006 txog Lub Kaum Ob Hlis 31, 2008, lub xeev tau siv txoj hauv kev los sau cov nqi ntxiv raws li cov cai ntawm cov khoom pwm tsim thiab muag los ntawm 230 lub tuam txhab pwm tseem ceeb, thiab tom qab ntawd rov qab 50% ntawm tus nqi ntxiv-ntxiv. them se.Cov nyiaj se rov qab tau siv tshwj xeeb rau kev hloov pauv, kev tiv thaiv ib puag ncig, kev txuag hluav taws xob thiab kev txo qis ntawm cov lag luam, thiab kev tshawb fawb thiab kev tsim cov khoom pwm.Ntawm 70 lub tuam txhab hauv Zhejiang Xeev, Ningbo suav txog 50, thaum Beilun muaj 15 (14 feem ntau tsom rau cov pwm tuag).
1.2 Beilun Tuag Casting Kev Lag Luam Chain
Vim muaj kev sib raug zoo ntawm cov pwm tsim thiab tsim cov txheej txheem thiab cov khoom siv pwm sab saud, kev kho cua sov, cov khoom siv pwm, pwm qauv, thiab cov khoom siv pwm hauv qab / cov khoom (cov khoom yas, qhov tuag-casting, thiab lwm yam), ntau yam pwm lag luam muaj ob qho tib si pwm thiab cov khoom.Yog li ntawd, cov saw hlau kev lag luam pwm tau muab faib ua peb ntu: "kev txhawb nqa kev lag luam", "pwm tsim thiab tsim cov lag luam", thiab "cov lag luam txuas ntxiv".
1.2.1 Upstream txhawb kev lag luam
Muaj ntau tshaj 150 pwm khoom, kev kho cua sov, forging mov, thiab lwm yam kev txhawb nqa kev lag luam muaj feem xyuam rau pwm tsim thiab tsim, nrog ntau tshaj 5000 tus neeg ua haujlwm.
1.2.2 Pwm tsim thiab tsim kev lag luam
Muaj tag nrho ntawm 1372 lub tuam txhab pwm hauv Beilun, ncaj qha koom nrog pwm thiab pwm ua haujlwm, nrog ntau dua 16000 tus neeg ua haujlwm.
(1) Kev txheeb xyuas ntawm cov lag luam pwm raws li kev faib tawm hauv cheeb tsam
Kwv yees li 70% ntawm lub regional faib ntawm pwm lag luam nyob rau hauv Beilun yog concentrated nyob rau hauv Daqi, raws li Xiapu accounting rau 11.37%.Regional concentration "yog ib tug yam ntxwv ntawm Beilun pwm lag luam.
(2) Kev faib tawm raws li qhov xwm txheej ntawm kev sau npe ua lag luam
Raws li kev txheeb cais ntawm Beilun Mould Enterprises los ntawm hom kev lag luam, ntawm 372 lub lag luam pwm, cov lag luam hauv tsev suav txog 96%.Cov tuam txhab ntiag tug ua lub luag haujlwm tseem ceeb "yog lwm tus yam ntxwv ntawm Beilun pwm lag luam.
(3) Kev faib tawm los ntawm hom pwm
Cov hom pwm tseem ceeb hauv Beilun yog cov pwm tuag-casting thiab yas pwm, nrog rau qee lub lag luam muaj ob qho tib si.Tuag-casting pwm account rau 75% mus rau 80%, yas pwm account rau 15% mus rau 20%, thiab lwm yam pwm account rau 5% mus rau 8%.
1.2.3 Downstream extension lag luam
Haum rau hom pwm, downstream extension lag luam feem ntau tsom rau tuag castings, yas qhov chaw, roj hmab qhov chaw, thiab stamping qhov chaw.Piv txwv li, nyob rau hauv Beilun Daqi, qhov twg zus tau tej cov tuag-casting yog concentrated, lub tuag-casting manufacturing kev lag luam tau tsim los ntawm cov pwm manufacturing kev lag luam.Daqi muaj ntau tshaj 60 lub tuam txhab tuag-casting, ntau tshaj 400 tuag-casting tshuab ntawm ntau hom, nrog specifications xws li 1250 kN txog 25000 kN.Muaj ntau dua 150 qhov chaw txuas ntxiv txuas ntxiv hauv Beilun.
1.3 Qhov kev faib ua feem ntawm Beilun tuag-casting pwm ntau lawm tus nqi hauv lub tebchaws
Raws li lub teb chaws tus qauv, pwm muab faib ua kaum pawg, nrog stamping pwm thiab yas pwm yog cov khoom tseem ceeb hauv Suav teb.Nrog rau txoj kev loj hlob ntawm kev lag luam tsheb thiab maus taus nyob rau hauv xyoo tas los no, qhov sib koom ntawm cov pwm yas thiab cov pwm tuag-casting tau nce xyoo los ntawm xyoo.Raws li kev txheeb cais ntawm Tuam Tshoj Mould Association, xyoo 2001, stamping pwm suav txog li 50% ntawm Tuam Tshoj tus pwm khoom qauv, yas pwm suav txog li 34%, pwm tuag-casting suav txog 6%, thiab lwm yam pwm suav nrog. txog li 10%;Nrog rau txoj kev loj hlob sai ntawm kev lag luam maus taus, tsheb, thiab khoom siv hauv tsev, kev lag luam tuag-casting tau tsim sai heev, thiab cov khoom tsim tawm ntawm cov pwm tuag casting tau nce.Raws li kev txheeb cais hauv xyoo 2003, cov pwm tuag-casting yog thib ob tsuas yog cov pwm pwm thiab cov pwm yas hauv cov ntsiab lus ntawm kev tsim khoom thiab ntau, suav txog li 8% ntawm tag nrho cov khoom ntawm ntau hom pwm;Nrog rau kev lag luam tsheb tau dhau los ua ib qho ntawm cov kev lag luam hauv Suav teb thiab kev txhim kho kev sib tw, ntsuab, thiab cov khoom txuag hluav taws xob, kev tsim cov hlau tsis-ferrous hlau tuag-casting qhov chaw thiab pwm tau nce ntxiv.Raws li kev txheeb cais ntawm lub teb chaws tuag-casting factories nyob rau hauv 2006, cov zis tus nqi ntawm tuag-casting pwm nyob rau hauv Tuam Tshoj tau accounted rau 10% ntawm tag nrho cov zis tus nqi ntawm cov pwm kev lag luam.
Ib lub hlis twg ntawm tag nrho cov khoom tsim tawm ntawm lub teb chaws tuag-casting pwm los ntawm Beilun tuag-casting pwm lag luam, uas tseem qhia txog txoj haujlwm tseem ceeb ntawm Beilun pwm kev lag luam hauv lub tebchaws.
2. Cov xwm txheej tam sim no ntawm Beilun tuag-casting pwm tshuab
Tam sim no, lub caj qaum pwm cov lag luam hauv Beilun tau siv CAD / CAM thev naus laus zis hauv kev tsim thiab tsim cov txheej txheem, thiab qee qhov ntawm lawv kuj tau ntxiv los ntawm CAE rau kev tsim simulation tsom xam.Thaum lub sij hawm ua cov txheej txheem, high-zoo tshav kub-resistant steel H13 tau dhau los ua lub ntsiab xaiv ntawm hlau.Nqus quenching, precision machining tom qab quenching, sib dhos thiab debugging ntawm lub pwm kaw tshuab, thiab kev ntsuam xyuas ntawm peb qhov kev ntsuas ntsuas tau dhau los ua cov txheej txheem tseem ceeb thiab txhais tau tias.Hais txog kev lag luam cov neeg ua haujlwm, muaj ntau tshaj 500 tus kws tshaj lij engineers, thiab qee lub tuam txhab tau qhia cov kws tshaj lij txawv teb chaws los ntawm lub teb chaws Yelemees, Nyiv, thiab Kaus Lim Qab Teb los coj pwm tsim thiab tsim khoom.Tib lub sijhawm, kev txhawb nqa kev lag luam xws li kev kho cua sov thiab kev ua haujlwm forging hauv Beilun kuj tau ua tiav qee yam kev txhim kho.
2.1 Tsim Technology
Pwm CAD / CAE / CAM yog ib qho tseem ceeb thev naus laus zis rau kev hloov cov pwm tsim thiab kev tsim khoom, ua rau cov kws tshaj lij engineering siv cov khoos phis tawj los tsim thiab ua kom zoo dua cov khoom lag luam, pwm qauv, txheej txheem tsim, thiab CNC machining.Qhov no tuaj yeem ua rau luv luv pwm tsim thiab tsim lub voj voog, txo cov nqi tsim khoom, thiab txhim kho cov khoom zoo.
Feem ntau cov tuam txhab lag luam hauv Beilun tau siv dav siv CAD / CAM thev naus laus zis hauv cov txheej txheem tsim pwm, thiab tau maj mam hloov los ntawm ob-seem qauv mus rau peb-seem tsim.Kev tsim khoom siv thev naus laus zis sib xyaw ua qauv tsim qauv peb sab thiab CNC tshuab cuab yeej tau maj mam nce, thiab cov txheej txheem digitization ntawm pwm tsim yog qhov siab.Mould manufacturing tuam txhab saum toj no qhov loj me tau tsim muaj nplooj siab 2D thiab 3D pwm tsim departments thiab yuav
Cov ntaub ntawv saum toj no yog los ntawm lub tsev qiv ntawv sau.Rau ntau tuag-casting pwm, thov xyuam xim rau Fenda Mould.
