Txoj Cai: Los ntawm txoj kev ntawm daim tawv nqaij cov nyhuv ntawm high-frequency tam sim no, lub high-frequency hluav taws xob lub zog muaj peev xwm yuav concentrated nyob rau saum npoo ntawm weldment, thiab qhov sib thooj nyhuv yuav siv tau los tswj txoj hauj lwm thiab ntau yam ntawm high-frequency tam sim no ntws txoj kev. . Thaum lub high-frequency tam sim no yuav tsum tau concentrated nyob rau hauv ib feem ntawm weldment, tsuav yog tus neeg xyuas pib thiab cov weldment tsim ib lub voj tam sim no thiab tus neeg xyuas pib nyob ze rau qhov no ntawm cov weldment, thiaj li hais tias lawv tsim nyob ib sab conductors rau. ib leeg, qhov kev xav tau no tuaj yeem ua tiav. . High-frequency welding yog raws li cov qauv tshwj xeeb thiab cov kev cai tshwj xeeb ntawm cov qauv ntawm cov vuam, feem ntau yog siv cov nyhuv ntawm cov tawv nqaij thiab cov nyhuv sib thooj, kom cov hlau nto ntawm cov welding yuav tsum tau welded sai sai kom ua tiav vuam.
High zaus welding yog txawv los ntawm welding kuj. Thaum lub sij hawm siv high-frequency welding, lub vuam tam sim no tsuas yog nyob rau hauv parallel kev sib cuag nrog nto ntawm lub workpiece; Qhov tam sim no ntawm tsis kam vuam ntws perpendicular mus rau vuam interface. Feem ntau, qhov zaus ntawm kev siv vuam ntau zaus raug xaiv nyob rau hauv thaj tsam ntawm 300 txog 450 kHz: kev siv vuam siv lub zog zaus ntawm 50 kHz.
High-frequency welding siv cov khoom tiv thaiv tshav kub ua lub zog. Thaum lub sij hawm vuam, cov hluav taws xob tiv thaiv tau tsim nyob rau hauv lub workpiece los ntawm high-frequency tam sim no heats lub nto txheej ntawm lub workpiece welding cheeb tsam mus rau ib tug molten los yog kaw yas lub xeev, thiab ces siv (los yog tsis siv) upsetting quab yuam kom ua tiav hlau bonding. Yog li ntawd nws yog ib qho khoom theem tsis kam vuam txoj kev. High-frequency welding yuav muab faib ua kev sib cuag high-frequency welding thiab induction high-frequency vuam raws li txoj kev uas high-frequency tam sim no generates tshav kub nyob rau hauv lub workpiece. Nyob rau hauv kev sib cuag high-frequency welding, high-frequency tam sim no yog nkag mus rau hauv lub workpiece los ntawm mechanical contact nrog lub workpiece. Nyob rau hauv induction high-frequency vuam, lub high-frequency tam sim no generates ib tug induced tam sim no nyob rau hauv lub workpiece los ntawm lub coupling kev txiav txim ntawm induction kauj sab nraum lub workpiece. High-frequency welding yog ib txoj kev vuam tshwj xeeb, thiab cov cuab yeej tshwj xeeb yuav tsum tau nruab raws li cov khoom. Kev tsim khoom siab, vuam ceev txog 30m / min. Nws yog tsuas yog siv rau vuam longitudinal seams los yog kauv seams thaum tsim cov kav dej.
High zaus welding muaj cov hauv qab noyam ntxwv:
1. Txij li thaum tam sim no muaj concentrated nyob rau hauv lub vuam cheeb tsam, lub cua kub ceev ceev heev, yog li ntawd lub vuam ceev yuav siab li 150-200m / min.
2. Vim lub vuam ceev ceev thiab muaj zog nws tus kheej-txias cov nyhuv ntawm lub vuam, tsis tsuas yog lub tshav kub cuam tshuam cheeb tsam me me, tab sis kuj oxidation tsis yooj yim rau tshwm sim, yog li cov qauv thiab kev ua tau zoo ntawm cov vuam yog zoo heev.
3. Qhov saum npoo ntawm qhov vuam tsis tuaj yeem raug ntxuav ua ntej vuam, yog li txhim kho kev ua haujlwm zoo.
4. Muaj ntau hom hlau uas tuaj yeem welded, thiab cov khoom muaj ntau yam duab thiab specifications.
Cov ntsiab lus ntawmob qhov teebmeem lojntawm high-frequency tam sim no nyob rau hauv high-frequency welding yog:
Cov nyhuv ntawm daim tawv nqaij- Thaum tus neeg xyuas pib txuas nrog alternating tam sim no, qhov tam sim no faib rau ntawm tus neeg xyuas pib yog qhov tsis sib xws, qhov ceev tam sim no maj mam nce los ntawm qhov nruab nrab ntawm tus neeg xyuas pib mus rau saum npoo, thiab feem ntau ntawm cov tam sim no tsuas yog ntws los ntawm tus neeg xyuas pib. Qhov qis dua qhov resistivity ntawm tus neeg xyuas pib, qhov ntau dua qhov permeability, thiab siab dua qhov zaus ntawm qhov tam sim no, qhov tseem ceeb ntawm daim tawv nqaij ua haujlwm.
Cov nyhuv sib thooj- Ib qho tshwj xeeb ntawm lub cev tshwm sim uas tam sim no tsom mus rau sab uas nyob ib sab ntawm tus neeg xyuas pib thaum muaj cov zaus tam sim no ntws hauv ob tus neeg xyuas pib tawm tsam ib leeg lossis hauv tus neeg xyuas pib reciprocating.
High-frequency welding feem ntau yog siv nyob rau hauv tam sim no ntau zaus ntawm 300 ~ 450kHz, qee zaum siv zaus tsawg li 10kHz.
