Xav txheeb xyuas cov khoom ntawm tus nqi pwm:
1. rhuav tshem cov nqi ntawm cov khoom;
2. txiav txim siab tus qauv rau kev xam cov nqi Cheebtsam;
3. txiav txim qhov chaw thiab qhov tseeb ntawm cov ntaub ntawv;
4. tsim qauv raws li cov kauj ruam dhau los.
Standardized Pwm Nqi Them Methodology:
Los ntawm kev ua pwm Los ntawm qhov pom ntawm tus nqi ntawm cov khoom siv, txawm tias nws yog cov nqi tsim, cov nqi khoom siv, cov txiaj ntsig thiab kev tswj hwm tus nqi, lossis kev debugging cov nqi thauj mus los thiab cov nqi ntawm cov qauv, tsuav yog tus neeg mob sau cov ntaub ntawv, ceev faj txog nyiaj txiag, kuj yooj yim txheeb xyuas thiab account rau; pwm ua cov nqi hauv qhov nyuaj tshaj plaws ntawm cov nqi ua haujlwm, uas kuj yog ib feem ntawm cov tuam ntxhab ntawm cov dej ntau dua. Kev ua haujlwm los ntawm qhov pib roughing mus rau qhov ua tiav tom qab, thiab tom qab ntawd mus rau sab nraum qab ntawm EDM, hlau txiav, polishing, thiab lwm yam., them nyiaj rau kev ua haujlwm thiab pwm tawm tswv yim, yog tias tsis yog qhov kev ua haujlwm cuam tshuam, xav txheeb xyuas tus nqi sib xws ntawm qhov nyuaj. tseem yog qhov loj, tab sis tuaj yeem kawm tau los ntawm cov kev paub dhau los ntawm cov neeg muab khoom sib txawv, cov ntsiab lus thiab cov ntsiab lus. Txawm li cas los xij, nws muaj peev xwm kawm tau los ntawm cov kev paub dhau los ntawm cov neeg muag khoom sib txawv, sib sau ua ke thiab paub txog cov nqi ntawm cov khoom sib txawv.
Pwm Supply Chain Model:
Nyob rau hauv cov pwm manufacturing Processing muaj ib tug coj lub sij hawm voj voog, los ntawm lub sij hawm voj voog thiab ua ke nrog cov txheej txheem tsim, nrhiav tus nqi nruab nrab ntawm lub khw.
Kev kwv yees tuaj yeem ua kom tshem tau qee yam dej. Piv txwv li, qee txoj haujlwm yog ob npaug hloov thiab qee txoj haujlwm yog ib qho kev hloov pauv, raws li kev sib cais los ntawm tus neeg muag khoom kom pom tias lub sijhawm ua haujlwm sib tw, thiaj li txiav txim siab tus nqi ntawm tus neeg muag khoom.
Nkag siab tus neeg muag khoom cov khoom siv, paub nws tus neeg muag khoom tus nqi kom paub txog tus neeg muag khoom tus nqi. Feem ntau hais lus, cov tsoos pwm Hoobkas muaj peb cov ntsiab lus nyiaj tau los ntawm cov khoom siv, cov nqi ua haujlwm thiab cov nqi tswj; yog li ntawd, peb yuav tsum muaj kev nkag siab txog tus nqi ntawm cov khoom siv raw.
Tuag casting pwm Tus nqi yog tsim los ntawm cov hauv qab no:
- tus nqi tsim;
- cov nqi khoom siv;
- cov nqi ua haujlwm;
- kev tswj hwm thiab nqi zog;
- Cov nqi kuaj xyuas;
- Cov nqi kuaj pwm;
- Cov nqi thauj mus los;
- Cov nqi tom qab muag;
- Cov se
Cov nqi ntawm cov khoom siv thiab cov nqi tsim qauv kuj pom tau, lwm cov nqi xws li cov nqi tsim khoom, kev debugging, kev thauj mus los, kev siv tau, kev tswj cov nqi, cov nyiaj tau los, lwm cov nqi koom nrog lub thawv dub, yuav tsum tsim pwm cov nqi siv nyiaj. Supply saw xov xwm sib qhia theem yuav tsum tau ntxiv dag zog: xws li cov ntaub ntawv hloov kev tsim, thov kev kwv yees thiab lwm yam.
Tus nqi pwm pib muaj cov saum toj no 9 feem ntawm tus nqi, lub tuam txhab pwm dav hlau tseem yuav suav nrog cov nqi pabcuam ntawm kwv yees li 5% ntawm tus nqi pwm, qhov seem yog cov nyiaj tau los ntawm pwm.
1. tus nqi tsim:
Thiab cov nqi ua haujlwm ze ze rau tus nqi ua haujlwm, yog li peb yuav tsum nkag siab txog tus neeg muag khoom cov nyiaj ua haujlwm hauv cheeb tsam kom kwv yees tus nqi ua haujlwm zoo dua. Pwm tsim feem ntau suav nrog CAD cov qauv tsim & 2D kos duab, CAE ntws tsom xam thiab CAM programming. Txawm li cas los xij, thaum xav txog tus nqi tsim pwm feem ntau suav tias tsuas yog tus nqi ntawm CAD thiab CAE.
Tus nqi tsim
Feem ntau nyob ntawm qhov loj ntawm cov pwm, qhov nyuaj ntawm cov degree ntawm qhov nyuaj, qhov tseeb, cov pwm Hoobkas quotes txawv. Ningbo cheeb tsam feem ntau loj pwm accounted rau 2% ntawm tag nrho cov nqi, me me pwm tsim nqi 2.5% ~ 3%. General pwm tsim engineer nyiaj hli 8K ~ 12K lossis yog li ntawd, kev paub dhau los ntawm ntau tshaj 10 xyoo ntawm pwm pwm loj tuaj yeem tau txais ntawm 15W ~ 25W, technical Minister ntau tshaj 30W.
Kev tsim qauv feem ntau suav nrog CAD cov qauv tsim & 2D kos duab, CAE pwm khiav tsom, CAM ntau lawm department Programming.
2. Khoom siv:
Cov khoom ntawm tuag casting pwm feem ntau suav nrog tus nqi ntawm pwm thav duab (rack), pwm core (kernel). Tuag thav duab yog muab faib ua homemade thav duab thiab txheem tuag ncej. Vim tias qhov loj dua lub tonnage ntawm cov pwm, qhov ntau dua qhov yuav tsum tau ntawm cov pwm ua cov cuab yeej ua haujlwm stroke, yog li feem ntau ntawm cov pwm pwm yuav khoom outsourcing Qhov loj dua lub tonnage ntawm pwm, qhov loj dua qhov yuav tsum tau rau cov hlab ntsha ntawm cov khoom siv, yog li feem ntau ntawm cov pwm factories yuav outsourcing thiab yuav txheem pwm ncej.
Qhov loj dua lub tonnage ntawm pwm, qhov loj dua cov pwm cab kuj. Feem ntau, qhov loj ntawm pwm thav duab, tus nqi qis dua, cov nqi siv nyiaj raws li qhov hnyav ntawm cov nyiaj ncaj qha, tab sis kom tshem tawm qhov sib txawv ntawm cov pwm taw. Pwm cov khoom siv feem ntau yog 45 #, 50 #, 55 # steel, 50 # steel pwm ncej nqi hauv 12 ~ 13 yuan / Kg.
Raws li tus tsim lub neej ntawm tuag-casting pwm
Xaiv cov khoom siv ntawm cov ncej tuag, vim yog aluminium alloy tuag lub neej feem ntau nyob rau hauv 8 ~ 100, 000 lub sij hawm tuag, cov ncej tuag tuaj yeem rov qab siv tau raws li lub neej ntawm 30W ~ 40W. Yog li peb yuav tsum xav txog qhov rov qab siv cov pwm thav duab hauv cov ntawv luam ntawm pwm txhua hnub.
Lub sij hawm tuag ntawm cov pwm mos yog tsawg heev, tsuas yog ob peb puas lub sij hawm tuag, tsis tuaj yeem siv cov pwm pwm, ncaj qha siv cov khoom siv tseem ceeb.
Tus nqi ntawm cov khoom siv feem ntau yog tus nqi ntawm cov pwm thiab cov tub ntxhais. Nws yuav tsum raug sau tseg tias yog lub neej pwm tuaj, npaj qhib daim ntawv pwm, yuav tsum tau mus txheeb xyuas seb cov pwm tuaj yeem rov qab siv dua; Yog tias tuaj yeem rov siv tau, ces luam cov pwm tuaj yeem txo qis heev. Cov nqi kho cua sov, rau kev tuag casting tuag, cov nqi kho cua sov kuj yog lub taub hau loj, suav nrog tempering, lub tshuab nqus tsev quenching, nitriding thiab lwm cov kauj ruam ntawm tus nqi. Tus nqi tshwj xeeb ntawm qhov siab thiab qis yog nyob ntawm qhov loj ntawm tus neeg muag khoom. SWPH13 Beilun Xingbo 8 yuan los yog li ntawd, ib xyoos lub ntim yuav muaj ib tug nyiam tus nqi ntawm 6 ~ 6.5 yuan / Kg; Nitriding kev kho mob ntawm 2 ~ 3 yuan / Kg; Ib Shengbai cov ntaub ntawv 25 yuan los yog li ntawd, tus nqi cog lus ntawm 17 yuan los yog li ntawd.
3. Cov nqi tsim khoom:
suav nrog cov cuab yeej siv tshuab, lub tshuab hluav taws xob, cov xaim txiav thiab lwm yam khoom siv thiab cov nqi zog xws li kev sib txuam pwm, polishing. General pwm ua cov nqi yuav tsis pub tshaj 20% ntawm tus nqi ntawm tag nrho cov pwm.
5. Kev soj ntsuam cov nqi: feem ntau yog rau qhov loj me ntawm cov pwm, electrode, cov txheej txheem kev soj ntsuam cov tub ntxhais tuag thiab kev tshuaj xyuas lub Hoobkas tom ntej, cov nqi tshuaj xyuas suav nrog 1-2% ntawm tag nrho cov nqi
4. kuaj pwm kev thauj mus los thiab ntim cov nqi:
General pwm tuam txhab sab hauv tas li yog 2 lub sij hawm sim pwm Performance index, 800T pwm hauv qab kev sim pwm nqi 1-1.5%; 800T saum toj no sim pwm tus nqi 2%. Aluminium alloy tuag casting sim pwm tus nqi kuj pheej yig, thiab magnesium alloy tuag casting sim pwm tus nqi yuav siab dua, vim magnesium alloy ntawm cov khoom siv kev nyab xeeb kev ua tau zoo dua; magnesium alloy khoom chav tsev nqi siab dua; ntxiv rau magnesium alloy tuag casting rauv thiab aluminium alloy tsis zoo ib yam. Nws yuav tsum raug sau tseg tias kev sim pwm dav dav
Tus naj npawb ntawm cov sij hawm yuav tsum tsis txhob ntau tshaj 3 zaug, yog tias ntau tshaj 3 zaug, tus nqi ntawm kev sim pwm yuav tsum tau yug los ntawm lub Hoobkas pwm nws tus kheej, vim nws yog vim lawv pwm nws tus kheej muaj teeb meem tsuas yog coj mus rau qhov xav tau. ntau sim pwm. Tsis tas li ntawd, cov kev txwv ntawm cov cuab yeej yuav tsum tau debugged kom raug kom ntseeg tau tias qhov kev sim pwm du.
Tus nqi thauj mus los yog nyob ntawm tus neeg siv khoom qhov chaw faib khoom, feem ntau 0.5%, 1.5% rau kev ncua deb. Pwm yog cov khoom hnyav, ib qho kev thauj mus los yuav yog lub tsheb tsuas yog tuaj yeem thauj cov pwm, yog li tus nqi thauj khoom yuav siab dua.
5. Kev pab cuam tom qab muag thiab cov se:
Cov nqi kev pab cuam tom qab muag feem ntau suav txog 5% ntawm cov kev cai tshwj xeeb tshwj tsis yog cov pwm.
Cov se feem ntau raug tshem tawm ntawm cov khoom siv credits lub tuam txhab yuav tsum tau them 9%.
Cov nqi saum toj no feem ntau sawv cev rau 90% ntawm lub tuam txhab pwm cov xwm txheej, cov nyiaj tau los tag nrho ntawm 15% -18%.
Tshem tawm cov khoom siv depreciation, qiv nyiaj hauv tuam txhab, nyiaj pov hwm nyiaj laus Cov yam ntxwv xws li kom ntseeg tau tias 5% -8% ntawm lub tuam txhab nyiaj tau txais txiaj ntsig zoo heev.
