Tsim cov yeeb nkab loj khoov los ntawm Forging thiab Extrusion
Taw qhia:
Cov yeeb nkab loj khoov ua lub luag haujlwm tseem ceeb hauv ntau daim ntawv thov kev lag luam, feem ntau yuav tsum tau ua tib zoo xav txog cov khoom siv thiab cov txheej txheem tsim khoom. Cov kev khoov no yog qhov tseem ceeb rau kev tsim cov kav dej thiab cov kav dej uas taug kev hauv lub tsev ib puag ncig, kom ntseeg tau tias cov kua dej thiab cov pa ua haujlwm tau zoo. Kab lus no tshawb txog ntau txoj hauv kev ntawm shaping cov yeeb nkab loj khoov thiab tsom rau forging thiab extrusion raws li cov txheej txheem tsim tau zoo. SINO SPECIAL METAL yog ib tus neeg muab kev ntseeg siab ntawm cov kav dej, flanges, thiab fittings, npaj los pab koj cov kev xav tau.
Shaping Method rau Cov Yeeb Nkab Loj Loj:
Cov yeeb nkab loj khoov tsis tshua muaj ua raws li cov ntu ncaj qha los ntawm cov chaw tsim khoom. Hloov chaw, lawv dhau los ua cov txheej txheem tom qab tsim khoom kom ua tiav ntau lub kaum sab xis thiab teeb tsa. Cov hauv qab no yog cov txheej txheem rau shaping yeeb nkab khoov:
1. Hmoov Metallurgy:
- Nyob rau hauv txoj kev no, cov ntaub ntawv hmoov yog compacted ntawm chav tsev kub kom ua tau raws li qhov xav tau ceev thiab lub zog. Tom qab ntawd, cov khoom yog sintered ntawm qhov ntsuas kub. Cov yam ntxwv xws li cov khoom siv ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom cov tshuab ua kom zoo nkauj sintering kub sintering lub sij hawm sintering lub sij hawm sintering sintering time , additive quantity , proportions , and the type of coupling agent can influence the size and performance of the khoov.
2. Extrusion:
- Extrusion ntawm cov yeeb nkab loj khoov yog feem ntau ua tiav siv ob-ntsia hlau extruders.
3. Txhaj Molding:
- Txoj kev no suav nrog kev sib tsoo siab los cais cov yaj mus rau hauv cov hmoov zoo thiab kab noj hniav. Kev siv me me-inch nozzles nrog nce shear kev ua tau zoo, ua ke nrog qhov tsim nyog ceev ceev, ua rau cov kav dej khoov tau zoo.
4. Tshuab Moulding:
- Cov yeeb nkab loj khoov ua los ntawm cov ntaub ntawv uas muaj siab yaj nro thiab tsawg sagging tuaj yeem tsim tau siv tshuab molding. Qhov no yog qhov tshwj xeeb tshaj yog rau kev tsim cov thawv loj loj.
5. Secondary forming:
- Tom qab pib shaping, kev tsim theem nrab yuav tsum siv zog sab nraud thiab cua sov cov khoom kom ua tiav cov duab khoov tshwj xeeb. Cov khoom yog ces txias kom khov kho khoov.
Factors yuav xav txog thaum Shaping:
Thaum lub sij hawm shaping ntawm cov yeeb nkab loj khoov, nws yog ib qho tseem ceeb kom muaj kev ncaj ncees ntawm cov khoom thiab zam kev puas tsuaj. Cov ntu tsis huv yuav tsum tsis txhob khoov, vim nws tuaj yeem ua rau cov yeeb nkab tsis ua haujlwm.
Forging thiab Extrusion:
Ntawm ntau txoj kev shaping, forging thiab extrusion yog dav siv nyob rau hauv kev tsim cov yeeb nkab loj khoov.
Forging Method:
1. Cov khoom siv raw rau forging loj yeeb nkab khoov yog feem ntau puag ncig billets.
2. Cov billets no raug txiav rau hauv kwv yees li 1-meter ntev uas siv lub tshuab txiav thiab muab tso rau hauv qhov cub kom sov.
3. Cov billets yog rhuab mus txog 1200 degree, siv hydrogen los yog acetylene ua roj.
4. Kev tswj qhov kub thiab txias hauv qhov cub yog qhov tseem ceeb.
5. Tom qab cua sov, lub voj voog puag ncig yog extruded los ntawm lub cub tawg.
6. Ib txoj hauv kev zoo rau kev tho yog lub conical roller tho tshuab, uas muaj kev ua haujlwm siab thiab cov khoom zoo.
7. Tom qab tho, cov yeeb nkab pierced yog raug rau peb-yob ntoo khaub lig-rolling, nruam dov, los yog extrusion los ua nws ntxiv.
8. Cov yeeb nkab kawg raug muab tshem tawm thiab siv lub tshuab sizing.
Xaus:
Cov yeeb nkab loj khoov yog cov khoom tseem ceeb hauv cov kav dej, thiab ua kom lawv zoo yog qhov tseem ceeb rau kev ua haujlwm zoo. Thaum muaj ntau txoj hauv kev muaj rau kev tsim cov yeeb nkab loj khoov, forging thiab extrusion yog cov txheej txheem zoo uas ua rau cov kav dej nrog cov khoom zoo heev. SINO SPECIAL METAL yog koj tus neeg muag khoom ntseeg siab rau cov kav dej, flanges, thiab fittings, npaj los pab koj xav tau. Rau kev nug thiab kev yuav khoom, thov hu rau peb. Peb tau cog lus los muab cov khoom lag luam zoo thiab kev txawj ntse kom tau raws li koj cov kev xav tau.
