Ndedzipi nheyo dze high-frequency kuomesa michina?

(1) Nheyo dzinokosha

Isai workpiece mune inductor ronda rine mhango yemhangura chubhu. Mushure mekupfuura mukati mepakati frequency kana yakakwira frequency alternating ikozvino, yazvino induced yeiyo frequency inoumbwa pamusoro peiyo workpiece, uye pamusoro kana chikamu chechikamu chinokurumidza kupisa (tembiricha inogona kuwedzerwa mukati memasekondi mashoma) 800 ～1000 ℃, iyo musimboti ichiri padyo nekamuri tembiricha) Mushure memasekondi mashoma, pfapfaidza (kunyudza) kutonhora kwemvura (kana kupfapfaidza kunyudza mafuta kutonhora) nekukurumidza uye nekukasira kupedza basa rekunyudza, kuitira kuti nzvimbo kana chikamu cheworkpiece chigone kusangana. izvo zvinoenderana nekuoma zvinodiwa.

(2) Kusarudzwa kwekupisa nguva

Pakupisa kwekamuri, hukama huri pakati pehupamhi δ (mm) yezvino induced inoyerera ichipinda pamusoro pechishandiso chekushanda uye ikozvino frequency f (HZ) ndeyokuti kuwanda kunowedzera, kudzika kwekupinda kwezvino kunoderera, uye kuoma kwemukati kunoderera.

Anowanzo shandiswa ma frequency azvino ndeaya:

1. High frequency heat: 100～500KHZ, inowanzoshandiswa 200～300KHZ, ndeye electronic tube type high frequency heat, iyo yakaoma layer yakadzika ndeye 0.5～2.5mm, inokodzera zvikamu zviduku uye zvepakati.

2. Yepakati frequency kudziyisa: Iyo yazvino frequency ndeye 500～10000HZ, kazhinji 2500～8000HZ, iyo magetsi emagetsi midziyo ndeye mechaniki yepakati frequency kupisa mudziyo kana silicon inodzorwa yepakati frequency jenareta. Kudzika kweiyo yakaoma layer ndeye 2～10 mm. Inokodzera madhayamita mahombe, magiya epakati uye makuru, nezvimwe. 3. Simba rekupisa kwemagetsi: Ikozvino nguva ndeye 50HZ. Uchishandisa magetsi emagetsi emagetsi ekudziya magetsi, kudzika kweiyo yakaomeswa layer inogona kusvika 10-20mm, iyo inokodzera kudzima kwepamusoro pemahombe-diameter workpieces.
