Kodi High-frequency Quenching ndi chiyani?

High-frequency kuzimitsaamagwiritsidwa ntchito kwambiri kuzimitsa zitsulo zamakampani.Ndi mtundu wa zitsulo kutentha mankhwala njira kuti kumapangitsa workpiece pamwamba kutulutsa zina anachititsa panopa, mwamsanga kutentha pamwamba pa mbali, ndiyeno mwamsanga quenching.Induction Kutentha zipangizo, ndiko, workpiece kupatsidwa ulemu Kutentha, kuti pamwamba quenching. zida.

Mfundo yotenthetsera kutenthetsa: Chogwirira ntchito chimayikidwa mumphepo ndi chitoliro chamkuwa chopanda kanthu mu sensa, mutatha kupeza ma frequency apakatikati kapena ma frequency alternating current (ac), opangidwa pamwamba ndi ma frequency a induced current, workpiece surface. kapena kutentha kwanuko mwachangu (masekondi pang'ono mpaka kutentha kwa 800 ~ 1000 ℃, pachimake akadali pafupi ndi kutentha kwa chipinda) patangopita masekondi angapo mwachangu utsi (kuviika) kuziziritsa kwamadzi (kapena kupopera mafuta kumiza kuzirala) kumiza kwathunthu ntchito yamoto, workpiece pamwamba kapena m'deralo kuti akwaniritse kuuma kofananako.

Poyerekeza ndi kuzimitsa kutentha wamba, ili ndi:

1. Kuthamanga kwachangu kumathamanga kwambiri, komwe kumatha kukulitsa kuchuluka kwa kutentha kwa thupi A ndikufupikitsa nthawi yosinthira.

2. Martensite yabwino kwambiri ya cryptocrystalline martensite ingapezeke pamtunda wa workpiece pambuyo pozimitsa, ndipo kuuma kumakhala kochepa kwambiri (2 ~ 3HRC) .

3. Chogwiritsiridwa ntchito chogwiritsidwa ntchito ndi ndondomekoyi sichophweka kuti chikhale ndi oxidize ndi decarbonize, ndipo ngakhale ena mwa workpiece akhoza kusonkhana mwachindunji ndikugwiritsidwa ntchito pambuyo pokonza.

4, wosanjikiza wowumitsa ndi wakuya, wosavuta kuwongolera magwiridwe antchito, osavuta kuzindikira makina, makina opangira.

5, kutentha pamwamba pa moto kuzimitsa

Kuzimitsa pafupipafupi kumagwiritsidwa ntchito pa chogwirira ntchito chomwe chimafunika kunyamula katundu wosinthika monga torsion ndi kupinda.Zimafunika kuti pamwamba pake ikhale ndi kupsinjika kwakukulu kapena kuvala kukana kuposa pachimake, ndipo pamwamba pa workpiece iyenera kulimbikitsidwa.Ndi oyenera zitsulo ndi mpweya zili We = 0.40 ~ 0.50%.
