Kutentha mankhwala ndondomeko pamwamba kuzimitsa

kuumitsa padziko

Zigawo zina zimakhala ndi katundu wosinthasintha monga torsion ndi kupindika ndi katundu wokhudzidwa pamene chogwirira ntchito chili mu workpiece, ndipo pamwamba pake imakhala ndi kupsinjika kwakukulu kuposa pachimake. Pankhani ya kukangana, kusanjikiza pamwamba kumavala nthawi zonse, kotero kuti pamwamba pa zigawo zina zimafuna mphamvu zambiri, kuuma kwakukulu, kukana kuvala kwambiri komanso kutopa kwambiri. Kulimbitsa pamwamba kokha kungakwaniritse zofunikira pamwambapa. Chifukwa kuzimitsa pamwamba kumakhala ndi ubwino wochepetsera pang’ono komanso kutulutsa kwakukulu, kumagwiritsidwa ntchito kwambiri popanga.

Malinga ndi njira zosiyanasiyana zotenthetsera, kuzimitsa kwapamtunda kumaphatikizapo kuzimitsa kutentha kwapamtunda, kuzimitsa moto wamoto, kuzimitsa kwamagetsi pamagetsi, etc.

Induction Heating Surface Kulimbitsa

Kuwotcha kwa induction ndikugwiritsa ntchito induction ya electromagnetic kupanga mafunde a eddy mu chogwirira ntchito kuti mutenthetse chogwirira ntchito. Poyerekeza ndi kuzimitsa wamba, kutenthetsera kutentha pamwamba pa quenching kuli ndi izi:

1. Gwero la kutentha liri pamwamba pa chogwirira ntchito, kutentha 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. Ndizopindulitsa kugwiritsa ntchito zomwe zingatheke, kupulumutsa chuma, ndi kukonza moyo wautumiki wa magawo;

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

6. Kuwongolera makina ndi makina;

7. Osagwiritsidwa ntchito kokha kuzimitsa pamwamba komanso pakuwotcha kolowera komanso kutentha kwamankhwala.
