Cov khoom siv vuam ntawm cov vuam neeg hlau txais yuav cov vuam vuam sib txuas, thiab cov vuam vuam yog ntsia tom qab vuam vuam, yog li lub tshuab hloov pauv yuav tsum me me li sai tau. Rau cov transformers nrog lub peev xwm me, 50Hz fais fab zaus AC tuaj yeem siv tau, thaum lub tshuab hluav taws xob muaj peev xwm loj dua, inverter tshuab tau siv los hloov 50Hz fais fab zaus AC rau hauv 600-700Hz AC, kom lub ntim ntawm transformer txo. thiab lightened. Tom qab qhov hluav taws xob hloov pauv, nws tuaj yeem txuas ncaj qha nrog 600-700Hz alternating tam sim no, lossis nws tuaj yeem kho ob zaug thiab welded nrog ncaj qha tam sim no. Cov kev ntsuas vuam yog kho los ntawm timer. Lub timer tshiab tau microcomputerized, yog li cov neeg hlau tswj txee tuaj yeem tswj tau lub timer ncaj qha yam tsis muaj qhov cuam tshuam ntxiv. Cov vuam vuam ntawm qhov chaw vuam neeg hlau feem ntau siv pneumatic vuam tongs. Qhov qhib nruab nrab ntawm ob lub electrodes ntawm pneumatic vuam tongs feem ntau tsuas yog ob-theem stroke. Ntxiv mus, thaum lub electrode siab tau teeb tsa, nws tsis tuaj yeem hloov pauv ntawm qhov xav tau. Nyob rau hauv xyoo tas los no, ib hom tshiab ntawm hluav taws xob servo qhov chaw vuam tongs tau tshwm sim, raws li pom nyob rau hauv daim duab 4. Qhov qhib thiab kaw ntawm lub vuam tongs yog tsav los ntawm lub servo lub cev muaj zog, thiab lub encoder tawm tswv yim, thiaj li hais tias qhib degree ntawm vuam. Tongs tuaj yeem xaiv tau thiab preset raws li qhov xav tau tiag tiag. Ntxiv mus, lub zog nias ntawm cov electrodes kuj tuaj yeem hloov kho steplessly.
Qhov tshiab hluav taws xob servo qhov chaw vuam phom muaj qhov zoo hauv qab no:
1) Lub voj voog vuam ntawm txhua qhov chaw vuam tuaj yeem txo qis heev, vim tias qhov qhib ntawm cov hlua vuam yog tswj hwm los ntawm cov neeg hlau, thiab cov neeg hlau tuaj yeem pib kaw thaum cov neeg hlau txav ntawm cov ntsiab lus; thiab cov hlua vuam tuaj yeem pib kaw; Tom qab ntawd, thaum lub vuam txuas tau qhib, tus neeg hlau tuaj yeem txav mus rau tib lub sijhawm. Nws tsis yog yuav tsum tau tos kom lub vuam tongs kaw tom qab cov neeg hlau nyob hauv qhov chaw lossis cov neeg hlau txav tom qab lub vuam vuam tau qhib tag nrho;
2) Qhov qhib qhov rooj ntawm qhov vuam vuam tuaj yeem hloov kho raws li qhov xwm txheej ntawm lub tshuab ua haujlwm, tsuav yog tsis muaj kev sib tsoo lossis cuam tshuam, qhov qhib qhov rooj raug txo kom ntau li ntau tau kom txuag tau qhov qhib ntawm lub vuam vuam thiab lub sij hawm nyob los ntawm qhov qhib thiab kaw ntawm cov welding tongs.
3) Thaum cov hlua vuam raug kaw thiab nias, tsis yog tsuas yog lub siab tuaj yeem hloov kho, tab sis kuj ob lub electrodes raug kaw maj mam thaum kaw, txo qhov cuam tshuam deformation thiab suab nrov.
