Nyob rau hauv qhov kev txhim kho yav dhau los, peb tau hais txog cov kauj ruam tseem ceeb ntawm kev tsis ua haujlwm, tshuaj xyuas, hoisting, thiab ua qhov kev hloov kho ntxhib ntawm koj lub tshuab ERW tshiab. Tam sim no, peb txav mus rau cov txheej txheem tseem ceeb ntawm kev sib dhos thiab kev hloov kho, qhov tseem ceeb hauv kev ua kom cov raj zoo tshaj plaws thiab kev ua haujlwm zoo.
Kev nkag siab txog kev hloov kho: Lub Hom Phiaj ntawm Kev Sib Raug Zoo
Kev hloov kho, nyob rau hauv cov ntsiab lus no, hais txog qhov zoo-tuning ntawm cov txheej txheem yob txoj kev los xyuas kom meej lub raj dawb paug khiav smoothly thiab stably los ntawm lub tshuab, thaum kawg tsim cov hlab uas ua tau raws li qhov yuav tsum tau specifications. Yog tias lub tshuab tuaj yeem tsim cov raj li no, ces nws tuaj yeem hais tias "kev hloov kho" tau ua tiav. Kev hloov kho ntxiv thaum lub sijhawm ua haujlwm tsis tu ncua feem ntau suav tias yog "kev daws teeb meem" thaum yam tsis ua haujlwm raws li qhov xav tau.
Kev hloov kho ntawm chav tsev weld tube tuaj yeem muab faib ua cov kauj ruam hauv qab no:
I. Kev npaj yog qhov tseem ceeb: Tshawb xyuas cov yob thiab ntsuas lub tshuab ua haujlwm
Ua ntej dhia mus rau hauv txoj kev hloov kho, kev npaj ua tib zoo yog qhov tseem ceeb:
- Roll Quality Inspection:Tsom ntsoov rau qhov zoo ntawm yob txoj kev zawj. Siv tus qauv los xyuas kom meej tias cov duab ntawm txhua yob ua raws li cov qauv tsim. Tshem tawm cov yob uas tsis ua raws li cov qauv. Tsis tas li ntawd, xyuam xim rau lub hauv paus txoj kab uas hla ntawm yob. Qhov no ua kom tag nrho cov yob tig hauv sync. Matched khub ntawm yob yuav tsum sib npaug ntawm qhov loj thiab cov duab.
- Machine Condition Check:Xyuas kom lub tshuab ua haujlwm zoo. Qhov no tuaj yeem sau tau raws li hauv qab no:
- Kab rov tav axes yuav tsum yog theem.
- Vertical axes yuav tsum ncaj.
- Roll positioning yuav tsum ruaj khov.
- Sliding Cheebtsam yuav tsum txav mus los dawb thiab du.
- Kev kho yuav tsum yooj yim ua.
Yog tias lub tshuab tsis ua raws li cov kev cai no, ua kev saib xyuas kom rov qab ua nws cov peev txheej ua tau zoo. Nws yog ib qho tseem ceeb los txhim kho txhua yam uas qhia txog tus cwj pwm hauv qab no: tsis tuaj yeem kho, tsis ruaj khov tom qab hloov kho, lossis txoj hauj lwm drifting.
II. Precise Alignment: Lub Foundation ntawm Zoo Tube Production
1. Groove Alignment
Groove alignment yog thawj kauj ruam hauv kev hloov kho.
- Xaiv ib lub 0.5mm steel hlau. Siv nws nrog cov feed-in rollers ntawm lub tshuab tsim rau lub chais ncaj nraim ntawm lub tshuab sizing raws li lub hauv paus ntev.
- Txiav txim siab qhov nruab nrab ntawm txoj kab yob. Ruaj ntseg cov hlau hlau thiab teeb tsa ua ib txoj kab ncaj nraim thiab zoo li qub.
- Xyuas kom tseeb tias qhov siab ntawm cov hlau hlau yog me ntsis siab dua li hauv qab txoj kab uas hla ntawm lub tiaj tus menyuam (2 hli lossis ntau dua). Ua li ntawd nws yuav zam kev sib cuag nrog lub arc ntawm qhov zawj uas yuav cuam tshuam rau kev ntsuas thiab qhov chaw. Cov hlau hlau no yuav yog cov kab siv rau kev sib tw groove.
2. Kab rov tav Roller Alignment
Muaj ob txoj hauv kev rau kev sib dhos kab rov tav yob:
- Txoj Kev 1: Siv lub tshuab hloov kho kom them nyiaj rau qhov sib txawv tuab ntawm ntau qhov zawj rollers. Txawm li cas los xij, yog tias qhov kev ua haujlwm raug tsis ua raws li qhov yuav tsum tau ua, qhov kev ua yuam kev tuaj yeem tshwm sim tau yooj yim tom qab sib dhos, cuam tshuam ncaj qha rau kev sib raug zoo ntawm cov duab yob.
- Txoj Kev 2: Siv lub ntsuas phoo los kho txoj haujlwm ntawm cov chais rau ntawm tus ncej, kom qhov nruab nrab ntawm qhov zawj ntawm txhua tus menyuam tuaj yeem ua ke nrog cov kab nruab nrab. Ib tug qauv tshwj xeeb yog siv los xyuas qhov chaw ntawm qhov chaw groove. Thaum kuaj xyuas, muab cov qauv tso rau hauv qhov zawj uas raug sib dhos, thiab tom qab ntawd maj mam nqa qhov kawg. Thaum cov hlau xaim tuaj yeem poob rau hauv qhov chaw nruab nrab ntawm qhov qauv, nws qhia tau hais tias qhov chaw nruab nrab ntawm qhov zawj yog qhov tseeb, txwv tsis pub, yuav tsum tau hloov axial txav. Qhov no yog ib txoj hauv kev yooj yim sib dhos.
Aligning lub Upper rollers siv cov yob hauv qab raws li kev siv. Tom qab xam qhov nruab nrab ntawm qhov nruab nrab ntawm lub sab sauv thiab qis qis, kho cov yob sab sauv mus rau txoj hauj lwm kab rov tav. Cov mis rau xam qhov axial center nrug yog raws li nram no:
- Qhib Groove Axial Center Distance Calculation:H = (Dlower + Dupper) ÷ 2 + t – a
- Kaw Groove Axial Center Distance Calculation:H = Dlower + 2R – aWhere:
- Dlower = Hauv qab txoj kab uas hla ntawm cov menyuam qis (mm)
- Dupper = Sab nraud txoj kab uas hla ntawm lub Upper roller (mm)
- t = Tube blank thickness (mm)
- R = Radius ntawm qhov sizing zawj (mm)
- a = Txo coefficient (0.1～0.5)
Tus nqi ntawm cov coefficient yog nyob ntawm qhov tuab ntawm lub raj khoob, qhov txo qis ntawm cov kab sab nraud ntawm lub raj, qhov loj thiab qhov tshwj xeeb, thiab qhov tseeb qhov xwm txheej xws li txoj kab uas hla ntawm ncej thiab elastic deformation ntawm ncej. Txawm li cas los xij, txias dov tsis tuaj yeem tshwm sim ntawm lub tshuab tsim. Txawm hais tias tus nqi ntawm kev txo qis yog qhov tsim nyog tuaj yeem ntsuas thiab kuaj xyuas los ntawm cov cim indentation ntawm cov fuse hlau. Thaum ua piv txwv, thawj zaug pib lub tsev thiab qhib nws mus rau qhov qeeb qeeb, tom qab ntawd khoov lub fuse hlau uas nws txoj kab uas hla yog me ntsis loj dua lub thickness ntawm lub raj dawb paug kom roughly phim lub zawj, thiab maj mam muab nws mus rau hauv lub dov zeb kom tau lub fuse hlau indentation.
Tom qab cov menyuam sab saud yog theem, qhov chaw nruab nrab ntawm qhov chaw nruab nrab ntawm cov menyuam sab sauv ntawm qhov qhib zawj kuj tseem tuaj yeem nruab nrog lub qauv-style plug gauge los xyuas seb qhov sib txawv ntawm ob sab ntawm cov menyuam yaus zawj thiab cov menyuam sab sauv yog tib yam. Yog tias lawv zoo li qub, axial txoj hauj lwm ntawm cov menyuam sab saud tuaj yeem raug kaw. Siv txoj kev kov rau cov grooves kaw los xyuas seb cov grooves sab sauv thiab sab qis haum ua ke.
3. Vertical Roller Alignment
Vertical roller alignment tuaj yeem muab faib ua peb kauj ruam:
- Ua ntej, txiav txim siab qhov qhib qhov sib txawv ntawm txhua pawg ntawm ntsug rollers, uas yog, axial centre nrug ntawm ob txoj hlua ntsug;
- Tom qab ntawd, nrhiav qhov chaw nruab nrab ntawm txhua pab pawg ntawm cov yob ntsug;
- Thaum kawg, kho qhov siab ntawm cov ntsug rollers.
Qhov qhib qhov sib txawv ntawm cov menyuam ntsug yuav tsum ua raws li qhov deformation qhib dav thaum lub sij hawm yob cov qauv tsim, thiab tom qab ntawd txo qis li 5 hli. Yog hais tias tus nqi ntawm shrinkage yog loj heev, nws yuav ua rau kom lub siab ntawm lub Upper ntug ntawm lub ntsug yob yob puab thiab ua rau kom lub load ntawm cov khoom.
Qhov nruab nrab ntawm cov menyuam ntsug yuav tsum tau ua raws tib lub sijhawm raws li cov menyuam kab rov tav kom ntseeg tau tias qhov chaw nruab nrab ntawm cov kab rov tav thiab ntsug cov menyuam nyob rau ntawm tib txoj kab nruab nrab. Tom qab pom cov kab nruab nrab ntawm txoj kab ntsug ntsug, cov hlau hlau tuaj yeem txo qis mus rau hauv qab txoj kab uas hla ntawm txoj kab rov tav rau cov menyuam zawj, thiab qhov siab ntawm cov menyuam ntsug tuaj yeem pib. Qhov siab ntawm cov menyuam ntsug yuav tsum yog nyob ntawm qhov siab ntawm qhov qis ntawm cov kab ntsug cov menyuam zawj sib piv qhov siab ntawm cov hlau hlau. Qhov siab ntawm thawj ob peb ntsug rolls ua ntej tsim yuav tsum tau txiav txim siab raws li cov txheej txheem tsis ntawm tus nqi ntawm lub nplhaib txiav ntawm cov menyuam qis.
4. Lwm yam Groove Alignments
Txoj kev sib dhos ntawm lwm cov duab yob tuaj yeem xa mus rau lub hauv paus ntsiab lus ntawm kev sib dhos ntawm cov yob thiab cov yob ntsug. Nws tsuas yog hais tias lub hauv qab txoj kab uas hla ntawm qhov qis ntawm cov menyuam ntawm cov ntawv qhia cov menyuam yuav tsum siab dua me ntsis ntawm cov kab siv los ntawm 0.5 ~ 2 hli (nyob ntawm txoj kab uas hla thiab phab ntsa thickness ntawm lub raj tsim). Lub burr kev txhawb nqa cov menyuam yuav tsum yog 0.5mm siab dua li cov kab siv los ua kom lub zog ruaj khov thaum npaj cov burrs sab nrauv thiab tiv thaiv kev npaj los ntawm kev dhia.
