Kev Tshawb Fawb Txog Kev Lag Luam ntawm Kev Xaiv Cov Saw Hlau Rau Cov Menyuam
Hauv cov tshuab xa hluav taws xob hauv kev lag luam, cov saw hlau, ua ib qho tseem ceeb uas sib xyaw ua ke kev ntseeg tau thiab kev hloov pauv tau, tau siv dav hauv ntau qhov chaw xws li kev tsim khoom siv tshuab, cov khoom siv ua liaj ua teb, thiab kev thauj mus los. Thaum xaivcov saw hlau, cov tuam txhab feem ntau poob rau hauv qhov ntxiab ntawm "tus nqi-tsuas yog" kev xaiv - ntseeg tias tus nqi yuav khoom pib qis dua, nws pheej yig dua, thaum tsis quav ntsej txog cov nuj nqis zais cia xws li kev poob sijhawm tsis ua haujlwm, cov nqi kho kom nce siab, thiab kev pov tseg hluav taws xob uas yuav tshwm sim los ntawm kev xaiv tsis raug. Kev xaiv kev lag luam tiag tiag tsom mus rau kev txav mus dhau ib qho nqi thiab siv "Tus nqi voj voog lub neej (LCC)" ua lub hauv paus kom ua tiav tus nqi zoo tshaj plaws thoob plaws hauv tag nrho cov txheej txheem ntawm kev yuav khoom, kev siv, thiab kev txij nkawm. Tsab xov xwm no yuav rhuav tshem lub hauv paus ntawm kev ua haujlwm zoo hauv kev xaiv cov saw hlau los ntawm peb theem: kev xaiv logic, cov yam tseem ceeb cuam tshuam, thiab cov ntsiab cai ua tau zoo.
I. Lub hauv paus ntsiab lus ntawm kev xaiv nyiaj txiag: Khiav tawm ntawm lub ntxiab "Tus nqi pib"
Qhov "kev ua haujlwm zoo ntawm kev lag luam" ntawm cov saw hlau tsis yog hais txog tus nqi yuav khoom xwb, tab sis yog kev suav tag nrho ntawm "kev nqis peev pib + cov nqi khiav lag luam + kev poob zais." Ntau lub tuam txhab xaiv cov saw hlau pheej yig los tswj cov nqi luv luv, tab sis ntsib qhov zaus hloov pauv siab ntawm "txhua peb lub hlis," ua ke nrog kev kaw cov kab ntau lawm vim yog kev saib xyuas thiab cov nqi ua haujlwm nce ntxiv, thaum kawg ua rau tag nrho cov nuj nqis ntau dua li cov ntawm cov saw hlau zoo.
Piv txwv li, siv lub chaw ua khoom siv hauv tsheb uas tsis yog tus qauv: Ib txoj saw hlau uas tsis yog tus qauv uas yuav ntawm 800 yuan muaj lub neej nruab nrab tsuas yog 6 lub hlis xwb, thiab yuav tsum tau hloov ob zaug hauv ib xyoos. Txhua lub sijhawm kho yog 4 teev. Raws li tus nqi tsim tawm txhua teev ntawm 5000 yuan, qhov poob zais txhua xyoo ncav cuag 40,000 yuan (suav nrog kev ua haujlwm kho thiab kev poob tawm thaum lub sijhawm kho), nrog rau tag nrho cov peev txheej txhua xyoo ntawm 800 × 2 + 40000 = 41600 yuan. Qhov sib txawv, xaiv cov saw hlau zoo uas ua raws li cov qauv DIN, nrog rau tus nqi yuav thawj zaug ntawm 1500 yuan, lub neej ntawm 24 lub hlis, tsuas yog xav tau ib zaug kho hauv ib xyoos thiab 2 teev ntawm lub sijhawm kho, ua rau tag nrho cov peev txheej txhua xyoo ntawm 1500 ÷ 2 + 20000 = 20750 yuan. Tag nrho cov nqi txo qis hauv ob xyoos yog ntau dua 50%.
Yog li ntawd, qhov teeb meem tseem ceeb hauv kev xaiv tsis yog "kim piv rau pheej yig," tab sis yog qhov sib npaug ntawm "kev nqis peev luv luv" thiab "tus nqi ntev." Tag Nrho Cov Nqi Siv Lub Neej (LCC) = Tus Nqi Yuav Khoom Pib + Tus Nqi Teeb tsa + Tus Nqi Txij Nkawm + Kev Poob Lub Sijhawm Tsis Ua Haujlwm + Tus Nqi Zog + Tus Nqi Pov Tseg. Tsuas yog xaiv ib txoj saw hlau raws li cov mis no thiaj li ua tau kom muaj txiaj ntsig zoo tshaj plaws.
II. Plaub Yam Tseem Ceeb Uas Cuam Tshuam Rau Kev Ua Haujlwm Zoo ntawm Kev Xaiv Cov Khoom Siv
1. Kev Sib Piv Kom Tseeb ntawm Qhov Thauj Khoom thiab Lub Zog: Tsis Txhob "Tsim Ntau Dhau" thiab "Tsis Tsim Tsawg Dhau" Lub zog ntawm cov saw hlau yuav tsum sib phim nrog qhov thauj khoom tiag tiag; qhov no yog lub hauv paus ntawm kev ua haujlwm zoo hauv kev lag luam. Kev nrhiav "lub zog siab" thiab xaiv cov qauv saw hlau ntau dua li qhov xav tau tiag tiag (piv txwv li, xaiv cov saw hlau nrog qhov thauj khoom ntsuas ntawm 100kN rau qhov thauj khoom tiag tiag ntawm 50kN) yuav ua rau cov nqi yuav khoom ntau dua 30%. Tib lub sijhawm, qhov hnyav ntawm cov saw hlau nce ntxiv yuav ua rau kev tiv thaiv kev sib kis ntau dua, ua rau 8% -12% nce hauv kev siv hluav taws xob txhua xyoo. Ntawm qhov tod tes, kev xaiv cov saw hlau tsis muaj zog txaus yuav ua rau qaug zog tawg, hnav cov saw hlau sai sai, thiab poob ntawm cov txiaj ntsig tso zis rau txhua teev ntawm lub sijhawm tsis ua haujlwm yuav sib npaug rau ntau zaus ntawm tus nqi yuav khoom ntawm cov saw hlau nws tus kheej.
Thaum xaiv ib tus qauv, nws yog ib qho tsim nyog los xam qhov kev nyab xeeb raws li kev faib tawm lub zog ntawm cov qauv thoob ntiaj teb (xws li DIN, ASIN) thiab cov kev cai xws li qhov ntsuas qhov hnyav, qhov cuam tshuam, thiab qhov siab tshaj plaws tam sim ntawd nyob rau hauv qhov xwm txheej ua haujlwm tiag tiag (qhov kev nyab xeeb ntawm ≥1.5 yog pom zoo rau cov xwm txheej kev lag luam thiab ≥2.0 rau cov xwm txheej hnyav). Piv txwv li, 12A series roller saw (suab 19.05mm) yog qhov tsim nyog rau kev sib kis nruab nrab, thaum 16A series (suab 25.4mm) yog qhov tsim nyog rau cov xwm txheej hnyav. Kev sib phim meej tuaj yeem tswj cov nqi pib thiab zam kev poob zais uas tshwm sim los ntawm lub zog tsis txaus.
2. Kev Hloov Kho Qhov Chaw Ua Haujlwm: Kev Xaiv Cov Khoom Siv thiab Cov Qauv Uas Tsim Nyog Cov xwm txheej ua haujlwm sib txawv muab cov kev xav tau sib txawv ntawm cov khoom siv thiab cov qauv ntawm cov saw hlau. Kev tsis quav ntsej txog cov yam ntxwv ntawm cov xwm txheej ua haujlwm thaum lub sijhawm xaiv yuav ua rau lub neej ntawm cov saw hlau luv dua thiab nce tus nqi txij nkawm: Rau cov xwm txheej ua haujlwm ib txwm muaj (kub ib txwm muaj, qhuav, lub teeb mus rau nruab nrab): cov saw hlau carbon txaus, muab qhov sib piv zoo tshaj plaws ntawm tus nqi-kev ua tau zoo, tus nqi yuav khoom pib qis, kev saib xyuas yooj yim, thiab lub neej ua haujlwm ntawm 1-2 xyoos; Rau cov xwm txheej ua haujlwm corrosive/av noo (tshuaj lom neeg, kev ua zaub mov, cov khoom siv sab nraum zoov): cov saw hlau stainless hlau lossis cov saw hlau nrog kev kho xeb saum npoo (galvanized, chrome-plated) yog qhov yuav tsum tau ua. Tus nqi yuav khoom pib ntawm cov saw hlau no yog 20% -40% siab dua li cov saw hlau carbon, tab sis lawv lub neej ua haujlwm tuaj yeem ntev dua 3-5 zaug, zam kev poob sijhawm thiab cov nqi zog ua haujlwm los ntawm kev hloov pauv ntau zaus.
Rau qhov kub thiab txias/hmoov av (hlau, khoom siv hauv tsev, khawb av): yuav tsum xaiv cov saw hlau uas ua los ntawm cov hlau uas tiv taus kub thiab txias lossis cov qauv kaw. Tus qauv kaw no txo cov hmoov av uas nkag mus rau hauv qhov sib txuas ntawm cov saw hlau, txo qhov hnav, ntev lub voj voog txij li 3 lub hlis mus rau 12 lub hlis, thiab txo cov nqi kho txhua xyoo ntau dua 60%.
Rau cov xwm txheej kev thauj mus los deb (kev faib khoom, kev siv tshuab ua liaj ua teb): Cov saw hlau thauj khoom ob chav yog qhov kev xaiv pheej yig dua. Lawv muaj qhov siab dua, qhov hnyav sib dua, kev tiv thaiv kev sib kis qis dua, kev siv hluav taws xob tsawg dua 15% piv rau cov saw hlau ib txwm muaj, kev faib khoom sib npaug dua, thiab lub neej ntev dua 20%.
3. Kev Tsim Qauv Sib Piv thiab Kev Ua Haujlwm Zoo ntawm Kev Sib Kis: Cov Nqi Zog Zais Cia
Qhov sib piv ntawm cov iav sib phim ntawm cov saw hlau thiab lub sprocket cuam tshuam ncaj qha rau qhov ua tau zoo ntawm kev sib kis, thiab qhov poob ntawm kev ua haujlwm thaum kawg txhais tau tias yog tus nqi zog. Kev tsim qauv sib piv iav tsis raug (xws li qhov tsis sib xws ntawm lub suab ntawm cov saw hlau thiab cov hniav sprocket) tuaj yeem ua rau muaj kev sib txuas tsis zoo, kev sib txhuam ntawm kev swb, thiab kev txo qis 5% -10% ntawm kev ua haujlwm ntawm kev sib kis. Rau lub cuab yeej 15kW ua haujlwm rau 8000 teev txhua xyoo, txhua qhov kev txo qis 1% ntawm kev ua haujlwm ua rau muaj kev siv hluav taws xob ntxiv 1200kWh ib xyoos. Ntawm tus nqi hluav taws xob kev lag luam ntawm 0.8 yuan / kWh, qhov no txhais tau tias ntxiv 960 yuan txhua xyoo.
Thaum xaiv lub sprocket, yuav tsum ua raws li "lub hauv paus ntsiab lus tsim qauv sib piv iav": tus lej hniav ntawm lub sprocket yuav tsum nyob nruab nrab ntawm 17 thiab 60 hniav kom tsis txhob hnav cov saw hlau ntau dhau vim muaj cov hniav tsawg dhau lossis kev tiv thaiv kev sib kis ntau dhau vim muaj ntau cov hniav ntau dhau. Tib lub sijhawm, kev xaiv cov saw hlau uas muaj cov hniav siab thiab qhov yuam kev me me (xws li A-series luv-pitch precision ob-txuas roller saw hlau) tuaj yeem txhim kho qhov tseeb ntawm kev sib txuas, ua kom ruaj khov ntawm kev sib kis tau zoo tshaj 95%, thiab txo cov nqi zog hauv lub sijhawm ntev.
4. Yooj Yim Kho: Qhov "Zais Cia" ntawm Kev Txo Lub Sijhawm Tsis Ua Haujlwm Lub sijhawm tsis ua haujlwm rau kev kho yog "qhov dub dub" hauv kev tsim khoom lag luam, thiab kev tsim qauv ntawm cov saw hlau roller cuam tshuam ncaj qha rau kev ua haujlwm zoo ntawm kev kho. Piv txwv li, cov saw hlau roller nrog cov txuas offset tso cai rau kev hloov kho qhov ntev ntawm cov saw hlau sai, txo cov sijhawm disassembly thiab sib dhos, thiab luv ib zaug kev kho los ntawm 2 teev mus rau 30 feeb. Ntxiv mus, cov qauv tsim txuas modular tshem tawm qhov xav tau kev hloov pauv saw hlau tag nrho; tsuas yog cov txuas qub yuav tsum tau hloov, txo cov nqi kho los ntawm 70%.
Tsis tas li ntawd xwb, yuav tsum xav txog qhov ua tau ntau yam ntawm cov khoom siv hnav: kev xaiv cov saw hlau uas ua raws li cov qauv thoob ntiaj teb ua rau muaj kev yooj yim rau kev yuav khoom thoob ntiaj teb ntawm cov khoom siv hnav xws li cov txuas, cov menyuam, thiab cov koob, zam kev ncua sijhawm ntev vim muaj qhov tsis txaus. Cov kev pabcuam OEM / ODM uas muab los ntawm qee lub npe tuaj yeem ua kom zoo dua cov qauv saw hlau raws li cov khoom siv xav tau, ua kom yooj yim rau kev saib xyuas.
