Dab tsi yog vuam neeg hlau?
Vuam neeg hlau yog ib qho kev lag luam neeg hlau koom nrog vuam (xws li txiav thiab txau). Nws feem ntau suav nrog cov neeg hlau thiab cov khoom siv vuam. Cov neeg hlau yog tsim los ntawm lub cev neeg hlau thiab lub txee tswj (khoom siv thiab software); Cov khoom siv vuam, xws li arc vuam thiab qhov chaw vuam, yog tsim los ntawm vuam fais fab mov (suav nrog nws cov kev tswj hwm), xaim feeder (arc vuam), vuam phom (clamp), thiab lwm yam. Lub tshuab ntse ntse yuav tsum tau nruab nrog lub ntsuas qhov system. , xws li lub laser lossis lub koob yees duab sensor thiab nws cov cuab yeej tswj. Hauv tsab xov xwm no, ob qhov sib txawv vuam neeg hlau yuav raug qhia, uas yog qhov chaw vuam neeg hlau thiab arc vuam neeg hlau.
1, Cov yam ntxwv ntawm qhov chaw vuam neeg hlau
Txij li thaum nws tau txais kev sib koom ua ke vuam clamp, lub transformer ntawm qhov chaw vuam neeg hlau yuav tsum me me li sai tau, thiab vuam transformer yog ntsia tom qab vuam clamp. 50Hz fais fab zaus AC tuaj yeem siv rau lub peev xwm me me, thiab siv tshuab hloov pauv zaus yog siv rau lub peev xwm loj. 50Hz fais fab zaus AC hloov mus rau 600-700 Hz AC kom txo qhov ntim ntawm transformer. Tom qab qhov hloov pauv voltage, nws tuaj yeem ncaj qha welded nrog 600-700hz AC lossis ntxiv kho los ntawm DC vuam. Welding parameters yog kho los ntawm timer. Tam sim no, lub timer tshiab tau tswj los ntawm microcomputer. Txij li cov neeg hlau tswj txee tuaj yeem tswj tau lub sijhawm ncaj qha, tsis tas yuav tsum muaj qhov sib cuam tshuam. Cov vuam vuam ntawm qhov chaw vuam neeg hlau yog tsav los ntawm hluav taws xob servo vuam tongs. Qhov qhib thiab kaw ntawm cov hlua vuam yog tsav los ntawm servo lub cev muaj zog thiab rov qab los ntawm cov lej disk. Qhov qhib ntawm cov hlua vuam tuaj yeem raug xaiv thiab ua ntej raws li qhov xav tau tiag tiag, thiab lub zog clamping ntawm cov electrodes tuaj yeem hloov kho steplessly.
BORUNTE cov qauv siv hluav taws xob muaj qhov zoo hauv qab no:
(1) Lub voj voog vuam ntawm txhua qhov vuam taw tes tuaj yeem ua kom luv luv, vim tias qhov qhib ntawm lub vuam taw tes tuav tau raug tswj hwm los ntawm cov neeg hlau. Thaum cov neeg hlau txav ntawm cov ntsiab lus, cov khoom siv vuam taw tes tuaj yeem pib kaw; Rau me ntsis vuam, tus neeg hlau tuaj yeem txav mus rau sab nraud thaum lub vuam taw tes tuav tau qhib, uas txhais tau hais tias cov neeg hlau tuaj yeem txav mus yam tsis tau tos kom cov neeg hlau nyob hauv qhov chaw, cov khoom siv hluav taws xob yuav tsum raug kaw lossis cov khoom siv hluav taws xob yuav tsum tau ua. qhib tag nrho.
(2) Qhov qhib ntawm cov hlua vuam tuaj yeem hloov kho raws li cov khoom ua haujlwm. Ntev npaum li tsis muaj kev sib tsoo lossis cuam tshuam, qhov qhib tuaj yeem txo kom ntau li ntau tau, thiab lub sijhawm qhib thiab kaw ntawm cov hlua vuam tuaj yeem cawm tau.
(3) Thaum lub electrode kaw thiab pressurized, tsis tsuas yog lub siab tuaj yeem hloov kho, tab sis kuj ob lub electrodes raug kaw me ntsis thaum lub electrode kaw, uas tuaj yeem txo qhov cuam tshuam deformation thiab suab nrov.
2. Cov yam ntxwv ntawm Arc vuam neeg hlau
Arc welding robots feem ntau siv cov roj tiv thaiv vuam txoj kev (MAG, MIG, TIG), thiab feem ntau yog siv thyristor, inverter, waveform tswj, mem tes lossis tsis yog mem tes vuam fais fab los nruab rau ntawm tus neeg hlau rau arc vuam. Txij li thaum cov neeg hlau tswj txee txais kev tswj hwm digital thiab cov khoom siv hluav taws xob vuam feem ntau yog kev tswj hwm analog, nws yog ib qho tsim nyog yuav tau ntxiv qhov sib txuas ntawm vuam fais fab mov thiab lub txee tswj.
Nyob rau hauv xyoo tsis ntev los no, txawv teb chaws neeg hlau manufacturers muaj lawv tus kheej tshwj xeeb txhawb vuam cov cuab yeej, thiab coj interface boards tau muab tso rau hauv cov welding khoom, yog li tsis muaj ntxiv interface box nyob rau hauv lub arc vuam neeg hlau system. Nws yuav tsum tau muab sau tseg tias lub sij hawm arc occupies ib tug loj feem nyob rau hauv lub voj voog ua hauj lwm ntawm lub arc vuam neeg hlau. Yog li ntawd, thaum xaiv lub vuam fais fab, lub peev xwm ntawm lub hwj chim qhov chaw yuav tsum tau txiav txim raws li 100 feem pua lub sij hawm tus nqi. Lub tshuab pub hlau tuaj yeem ntsia tau rau ntawm sab caj npab ntawm tus neeg hlau lossis muab tso rau ntawm tus neeg hlau. Lub hose nruab nrab ntawm cov phom vuam thiab cov xaim feeder yog luv luv, uas yog qhov tsim nyog rau kev tswj xyuas qhov ruaj khov ntawm cov xaim pub mis, thaum lub hose yog lub cev tseem ceeb ntawm tom kawg. Thaum tus neeg hlau vuam phom ua rau lub hose ntawm ib qho chaw nyob rau hauv lub xeev dabtsi yog khoov, nws yuav cuam tshuam rau cov hlau noj zoo. Yog li ntawd, qhov teeb meem ntawm kev ua kom ruaj ntseg ntawm cov xaim pub mis yuav tsum tau txiav txim siab thaum txhim kho cov hlau feeder.
