- Yog vim li cas rau khawb ntawm qhov chaw ntawm welded kav:
Kev siv cov yob-tsim welded kav yuav tsum tau lub sawb yuav tsum tau khoov transversely rau hauv ib lub voj voog. Qhov no yog ua tiav los ntawm deforming lub sawb los ntawm ib tug series ntawm yob nrog sib txawv groove duab. Txhua khub ntawm yob rotates ntawm ib tug tej yam ceev, tab sis cov linear ceev ntawm yob nto yog txawv vim lub voj voog sib hloov. Txawm li cas los xij, qhov sib txawv ntawm txoj kab nrawm ua rau zawv zawg kev sib txhuam ntawm cov sawb thiab cov txheej txheem sib sau, uas yog qhov tseem ceeb ua rau khawb ntawm qhov chaw ntawm cov yeeb nkab welded.
Feem ntau welded yeeb nkab units txais txoj kev kab rov tav. Rau chav tsev no, lub hauv qab txoj kab uas hla ntawm kev tsav tsheb rolls ntawm roughing yob, qhia lub nplhaib yob thiab sizing yob yog suav hais tias yog tus tsav txoj kab uas hla. Lub linear ceev ntawm cov yob hauv qab diameters yog qhov sib npaug ntawm qhov ceev ntawm lub strip. , vim qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv, qhov yob ntawm txhua yob ua rau cov txheeb ze loj zawv zawg kev sib txhuam ntawm cov sawb thiab yob nto, uas ua rau nto khawb.
Kev sib txhuam cuam tshuam rau qhov zoo ntawm qhov chaw, thiab kev sib txhuam yuav ua rau khawb. Thaum cov kev sib txhuam nce, qhov zoo siab ntawm lub sawb nce, thiab deformation ntawm cov sawb nce, ua rau cov menyuam ua rau cov hlua khi thiab tsim cov khoom khawb.
- Tsim nyog yob tsim thiab ua
1. Siv cov flange taug kev
Yuav kom txo tau tus txheeb ze zawv zawg ntawm lub sawb thiab yob nto, cov neeg tsav tsheb siv lub flange cov menyuam taug kev, ib qho kev txav flange rau cov menyuam qauv. Nws tsim yog tias cov flange mus txawv tebchaws tau txais kev txhawb nqa los ntawm cov kabmob, thiab nws txoj kev sib hloov ceev nyob ntawm qhov kev xa tawm ntawm cov sawb. Kev nrawm, sib txawv ntawm qhov ceev ntawm yob, siv hom yob no tuaj yeem txo tus txheeb ze zawv zawg ntawm cov sawb thiab qhov chaw ntawm yob, yog li txo lossis txawm tias tshem tawm khawb ntawm qhov chaw ntawm cov yeeb nkab welded.
2. Plaub-txheej txheej txheej
Ntxiv nrog rau kev siv cov flange rollers rau kev tsim, qee qhov welded yeeb nkab units siv plaub-cov menyuam sib sau. Four-roller forming yog siv rau kev qhia lub nplhaib rollers thiab sizing rollers. Lub sijhawm no, kab rov tav rollers siv cov menyuam ua haujlwm nquag thiab cov menyuam ntsug siv cov menyuam tsis muaj zog. Qhov ceev ntawm txoj hlua ntsug yog nyob ntawm qhov kev xa khoom ceev ntawm lub sawb yog qhov zoo los txo cov kev sib txheeb zawv zawg thiab zawv zawg kev sib txhuam ntawm cov sawb thiab qhov chaw ntawm cov menyuam ntsug.
3. khiav lub kaum sab xis thiab tshem tawm
Ntxiv nrog rau kev hloov cov yob tsim, yob hloov kho kuj tuaj yeem txo qhov khawb ntawm qhov chaw ntawm cov yeeb nkab welded. Ib txoj hauv kev yog ua kom tsim nyog lub kaum sab xis khiav tawm lossis tshem tawm ntawm ntug yob. Qhov kev sib txawv no tuaj yeem txo qhov siab ntawm lub sawb ntawm qhov chaw ntawd, yog li txo qhov siab ntawm lub strip. Txhawm rau txo qhov khawb ntawm qhov chaw, qhov sib txawv ntawm kev ua haujlwm tsis yog nyob ntawm cov khoom siv welded yeeb nkab, cov yeeb nkab txoj kab uas hla thiab cov yam ntxwv ntawm chav tsev, tab sis kuj nyob ntawm cov duab yob ntawm txhua tus menyuam thaum lub sij hawm tsim. Lub kaum sab xis khiav tawm los yog qhov sib txawv yuav tsum tau kom lub sawb tuaj yeem khiav tawm ntawm cov menyuam nto. Rau lub hom phiaj sib txawv Qhov zoo ntawm cov kav dej welded, xws li cov kav dej uas muaj zog tsawg-alloy steel qauv, tsis yog siab npaum li cov kav dej welded uas yuav tsum tau kho dua tshiab. Txhawm rau txo cov nqi tsim khoom, tsis tas yuav siv zog ntau dhau los txhawm rau tshem tawm qhov khawb ntawm qhov chaw (yog tias cov yob khawb yog nyob rau hauv cov qauv yuav tsum tau ua).
Cov txheej txheem kho saum npoo tuaj yeem tsim cov txheej txheem tawv tawv-tiv taus ntawm cov yob. Cov txheej hnav-resistant muaj xws li lub cev txheej, tshuaj txheej thiab thermal diffusion txheej. Cov khoom siv txheej feem ntau muaj titanium nitride thiab titanium carbide. Cov txheej tuaj yeem ua rau kom muaj zog ntawm cov yob. Hnav tsis kam thiab txo kev sib txhuam coefficient, tab sis daim ntawv thov ntawm yob hauv daim teb no yog txwv los ntawm yob deformation thiab nyuaj hauv kev kho. Thaum qhov roughness ntawm cov yeeb nkab steel yog qhov hnyav, kev kho deg ntawm cov yob tuaj yeem txiav txim siab.
Kev khawb ntawm qhov chaw ntawm cov yeeb nkab welded tej zaum yuav tshwm sim los ntawm cov laj thawj yooj yim xws li kev sib txhuam ntawm qhov chaw siab lossis qhov sib txawv ntawm cov kab nrawm ntawm cov yob nto. Txawm li cas los xij, nws yog qhov nyuaj rau kev txheeb xyuas thiab tshem tawm cov khawb ntawm qhov chaw. Tag nrho cov txheej txheem tsim muaj xws li kev tsim cov yob, kev teeb tsa thiab kev hloov kho ntawm lub yob, thiab lub tshuab lubrication. Kev siv tsim nyog yuav tsum tau txheeb xyuas txhawm rau tsim cov khoom zoo.
