Vuam txoj cai ntawm high zaus welded steel yeeb nkab: synergistic nyhuv ntawm daim tawv nqaij nyhuv thiab sib thooj nyhuv
Lub hauv paus ntsiab lus ntawm kev sib txuas ntawm high zaus welded steel yeeb nkab feem ntau yog ua raws li cov nyhuv ntawm daim tawv nqaij thiab cov nyhuv sib thooj ntawm cov zaus tam sim no. Cov nyhuv ntawm daim tawv nqaij txhais tau hais tias thaum high-frequency tam sim no dhau los ntawm ib tug hlau conductor, vim electromagnetic induction, qhov tam sim no ceev yog mas concentrated nyob rau saum npoo ntawm tus neeg xyuas pib, thaum lub tam sim no ceev nyob rau hauv lub conductor yog me me. Cov nyhuv no ua rau lub zog hluav taws xob ntau zaus los mloog zoo rau ntawm qhov chaw ntawm qhov vuam, yog li ua kom sov rau thaj tsam weld. Qhov kev siv ntawm daim tawv nqaij cov nyhuv yog ncaj qha proportional rau tam sim no zaus. Qhov siab dua qhov zaus, qhov siab dua qhov concentration ntawm tam sim no ntawm tus neeg xyuas pib nto. Yog li ntawd, kev siv cov vuam siv hluav taws xob feem ntau siv tam sim no nrog qhov zaus siab tshaj 300kHz kom ua tiav cov cua sov ntawm thaj tsam weld.
Cov txiaj ntsig sib thooj txhais tau hais tias thaum lub zog loj tam sim no ntws rov qab rau hauv ob qhov chaw nyob sib ze, vim yog kev sib cuam tshuam ntawm cov hlau nplaum, qhov tam sim no yuav mloog zoo rau ntawm ntug ntws ntawm ob tus neeg nyob ib sab. Cov nyhuv no tuaj yeem tswj tau txoj hauv kev ntws ntawm high-frequency tam sim no, ua rau nws muaj zog dua nyob rau hauv qhov chaw weld, yog li txhim kho qhov vuam efficiency thiab zoo. Nyob rau hauv cov txheej txheem ntawm kev siv vuam ntau zaus, cov nyhuv sib thooj yog pab kom txo tau lub zog poob, ua kom muaj cua sov txaus rau hauv qhov chaw vuam, thiab paub txog cov cua sov sai thiab zoo ib yam.
Nyob rau hauv cov txheej txheem ntawm high-frequency welding, high-frequency tam sim no yog nkag mus rau hauv lub workpiece los ntawm induction kauj los yog hu rau electrode, uas generates tshav kub rau hauv zos yaj cov hlau. Induction kauj yog ib qho cuab yeej uas hloov cov zaus tam sim no mus rau hauv electromagnetic induction zog. Nws tsim ib qho chaw sib nqus sib nqus nyob ib ncig ntawm lub workpiece, ua rau eddy tam sim no hauv workpiece, yog li cua sov cov hlau. Kev sib cuag electrode yog nyob rau hauv kev sib cuag ncaj qha nrog lub workpiece, qhia high-frequency tam sim no rau hauv lub workpiece thiab cua sov cov hlau los ntawm cov thermal nyhuv ntawm kuj. Ob txoj kev muaj lawv tus kheej qhov zoo thiab qhov tsis zoo. Induction vuam yog tsim rau tuab workpieces, thaum sib cuag vuam yog haum rau nyias workpieces.
Tom qab ntawd, los ntawm kev siv lub siab, cov hlau molten yog txias los ua ib qho kev sib koom tes ruaj khov. Nyob rau hauv cov txheej txheem vuam, lub siab thiab lub sij hawm daim ntawv thov muaj ib qho tseem ceeb cuam tshuam rau lub vuam zoo. Lub siab zoo tuaj yeem xyuas kom meej tias cov hlau molten ntws thiab fuses tag nrho los tsim cov vuam tuab, thaum lub siab ntau dhau tuaj yeem ua rau weld deformation lossis tsis xws luag. High-frequency welding muaj qhov zoo ntawm cov cua kub ceev ceev, me me tshav kub cuam tshuam cheeb tsam thiab siab weld zoo. Cov khoom siv kho tshuab thiab sealing kev ua tau zoo ntawm weld yog zoo heev, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm ntau yam haujlwm rau kev ua haujlwm ntawm cov kav dej.
