Nruab nrab-frequency resistance welding machines yog dav siv nyob rau hauv niaj hnub manufacturing industries xws li automotive Cheebtsam, hardware, sheet hlau fabrication, khoom vaj khoom tsev, electronics, thiab tshiab zog khoom.

Kuj tseem hu ua qhov nruab nrab zaus inverter qhov chaw vuam tshuab lossis nruab nrab zaus DC tsis kam vuam tshuab , cov tshuab no siv tshuab inverter los muab kev tswj xyuas meej dua ntawm vuam tam sim no thiab cov txheej txheem.

Tab sis li cas lub nruab nrab zaus kuj vuam tshuab ua hauj lwm? Nws qhov txiaj ntsig tseem ceeb yog dab tsi? Qhov kev lag luam thiab cov ntaub ntawv twg yog nws tsim nyog rau? Thiab dab tsi manufacturers yuav tsum xav txog ua ntej yuav ib tug?

Phau ntawv qhia no piav qhia txog txoj hauv kev ua haujlwm, qhov zoo tseem ceeb, kev siv, kev siv vuam tsis zoo, thiab kev xaiv cov kev xav ntawm nruab nrab-frequency resistance welding machines.

1. Dab tsi yog qhov nruab nrab-Frequency Resistance Vuam Tshuab?

Lub nruab nrab-zaus tsis kam vuam tshuab yog ib qho kev siv vuam tshuab uas siv cov tshuab nruab nrab zaus inverter los koom nrog cov hlau ua haujlwm.

Cov ntsiab lus kev lag luam uas muaj xws li:

• Medium-frequency kuj welding tshuab

• Medium-frequency chaw vuam tshuab

• Medium-frequency inverter chaw vuam tshuab

• Medium-frequency DC kuj welding tshuab

• Medium-frequency inverter vuam tshuab

Lub tshuab siv hluav taws xob tsis kam ua kom muaj cua sov ntawm cov hlau ua haujlwm.

Thaum lub sij hawm vuam, ob los yog ntau tshaj hlau Cheebtsam yog positioned ntawm electrodes. Cov electrodes siv siab thaum vuam tam sim no dhau los ntawm cov khoom ua haujlwm. Vim hais tias hluav taws xob kuj muaj nyob rau ntawm qhov chaw sib cuag, cua sov yog generated sai heev. Qhov cua sov no tsim ib qho molten weld nugget nruab nrab ntawm cov workpieces.

Tom qab lub vuam tam sim no nres, electrode siab yog khaws cia thaum lub weld nugget txias thiab solidifies, tsim qhov kawg weld point.

Cov txheej txheem yooj yim tuaj yeem sau tau raws li:

Electrode siab → Vuam tam sim no → Resistance tshav kub → Weld nugget tsim → Tuav thiab txias → Weld tiav

Tsis zoo li cov txheej txheem uas yuav tsum tau vuam hlau lossis cov khoom siv muab tub lim, qhov chaw vuam feem ntau koom nrog hlau los ntawm kev tswj hluav taws xob tam sim no thiab cov tshuab ua haujlwm siab.

2. Lub Nruab Nrab-Frequency Resistance Vuam Tshuab ua haujlwm li cas?

Lub hauv paus ntsiab lus ntawm kev tiv thaiv vuam yog ua raws li Joule cua sov.

Tus nqi ntawm tshav kub generated tuaj yeem sawv cev los ntawm:

Q = I² Rt

Qhov twg:

• Q = Thaum tshav kub kub generated thaum vuam

• Kuv = welding tam sim no

• R = hluav taws xob tsis kam nyob rau hauv qhov chaw vuam

• t = welding lub sijhawm

Thaum lub sij hawm welding tiag tiag, ntau yam tsis ua hauj lwm ua ke los txiav txim qhov kawg weld zoo.

Vuam tam sim no cuam tshuam ncaj qha rau cov cua sov tsim tawm.
