Mfundo ndi ubwino wa induction Kutentha pamwamba kuumitsa

Zigawo zina zimakhala ndi katundu wosinthasintha komanso zolemetsa monga torsion ndi kupindika panthawi yogwirira ntchito, ndipo mawonekedwe ake apamwamba amakhala ndi kupsinjika kwambiri kuposa pachimake. Pa nthawi ya kukangana, pamwamba pa pamwamba amavalidwa mosalekeza. Choncho, pamwamba wosanjikiza mbali zina chofunika kukhala ndi mphamvu mkulu, mkulu kuuma, mkulu kuvala kukana ndi mkulu kutopa malire. Kulimbitsa pamwamba kokha kungakwaniritse zofunikira pamwambapa. Chifukwa kuzimitsidwa pamwamba kumakhala ndi ubwino wochepetsera pang’ono komanso kutulutsa kwakukulu, kumagwiritsidwa ntchito kwambiri popanga.

Malinga ndi njira zosiyanasiyana zotenthetsera, kuzimitsa pamwamba kumaphatikizapo kuzimitsa kutentha kwapamtunda, kuzimitsa moto wamoto, komanso kuzimitsa kwamagetsi.

Kuwotcha kwapakatikati: Kutentha kwa induction ndikugwiritsa ntchito ma elekitirodi opangira magetsi kuti apange mafunde a eddy mu chogwirira ntchito kuti azitenthetsera chogwirira ntchito. Poyerekeza ndi kuzimitsa wamba, kutenthetsera kutentha pamwamba pa quenching kuli ndi zotsatirazi:

1. Gwero la kutentha lili pamwamba pa chogwirira ntchito, kuthamanga kwachangu kumathamanga, ndipo kutentha kwabwino kumakhala kwakukulu.

2. Chifukwa workpiece si kutenthedwa lonse, deformation ndi yaying’ono

3. Kutentha nthawi ya workpiece ndi yochepa, ndipo kuchuluka kwa okosijeni pamwamba ndi decarburization ndi yaing’ono.

4. Kulimba kwapamwamba kwa workpiece ndikwapamwamba, chidziwitso cha notch ndi chaching’ono, ndipo kuuma kwake, mphamvu ya kutopa ndi kukana kuvala kumakula kwambiri. Kuthandizira kugwiritsa ntchito kuthekera kwazinthu, kupulumutsa kugwiritsa ntchito zinthu, ndikuwonjezera moyo wautumiki wa magawo

5. Zidazi ndizophatikiza, zosavuta kugwiritsa ntchito komanso malo abwino ogwirira ntchito

6. Kuwongolera makina ndi makina

7. Osagwiritsidwa ntchito kokha pakuzimitsa pamwamba, komanso pakuwotcha kolowera komanso kutentha kwamankhwala.
