Ubwino wozimitsa ndi chiyani zida zotseketsa kwambiri palokha

Kugwiritsa ntchito quenching yapamwamba kwa nthawi yayitali kwakhala kukugwiritsidwa ntchito mumakampani azitsulo kwanthawi yayitali, pang’onopang’ono m’malo mwa zida zochizira kutentha kwachikhalidwe, ndikukula kwaukadaulo kopitilira muyeso wazitsulo kuti kuwongolera magwiridwe antchito a workpiece. Mitundu iwiri ya zida zozimitsira mafupipafupi, zomwe zimafanana ndi kuzimitsa kwafupipafupi, zimakhala ndi ubwino waumisiri wofanana, koma zida zozimitsa zosiyana zimasankhidwa malinga ndi zofunikira zamakono. Lero, tiyeni tiwone ubwino wozimitsa wa zida zozimitsira ma frequency apamwamba.

Kuzimitsa pafupipafupi kwambiri kumagwiritsa ntchito mfundo ya electromagnetic induction, ndipo kupangika komwe kumapangidwa kumatha kuchitapo kanthu kutentha, kutentha ndi njira zina pa workpiece. Ndiye ili ndi makhalidwe ndi ubwino zomwe zida wamba zilibe. Ubwino waukulu ndi:

1. Pamwamba pa workpiece si kophweka kuti oxidized. Chifukwa cha kutentha, workpiece mosavuta kukhudzana ndi mpweya, ndipo pamwamba ndi oxidized, zomwe zidzakhudza Kutentha zotsatira workpiece. M’malo mwake, njira yozimitsa maulendo apamwamba sikuti imangoyambitsa okosijeni wochuluka, koma kuthamanga kwa kutentha kwa workpiece kumakhala kofulumira, komwe kumapangitsa kuti ntchitoyo ikhale yabwino, ndipo chogwirira ntchitocho sichimapunduka kawirikawiri.

2. Muyezo wa pamwamba oumitsa wosanjikiza wa mkulu pafupipafupi quenching workpiece ndi mkati 1-1.5mm, amene si chimodzimodzi ndi wapakatikati pafupipafupi quenching. Kuzama kwa wosanjikiza wowumitsidwa wapakati pafupipafupi kuzimitsa kumatha kufikira mkati mwa 1-5mm, kotero kuzimitsa kwapakatikati kumagwiritsidwa ntchito ngati kuzimitsa kwanthawi yayitali sikungakwaniritse zofunikira. Inde, ngati ndi workpiece ndi wosanjikiza mozama, ife ntchito mphamvu-pafupipafupi kuzimitsa njira.

3. Njira yowotchera ya zida ndizotenthetsera zosalumikizana, zomwe zimatha kutenthetsa mwachangu gawo lachiwiri lopunduka.

4. Njira yozimitsira ya workpiece imatha kuyendetsedwa yokha, ndipo ikhoza kukhala ndi chida chozimitsa makina kuti chikwaniritse kuzimitsidwa kosalekeza, kuzimitsa kwa magawo ndi kusanthula kotsatira. Njira imeneyi ndi yabwino kwambiri kwa ma workpieces omwe ali ndi zofunika kwambiri.

5. Kugwiritsa ntchito kutentha kwa kutentha kwa zipangizo zozimitsa pafupipafupi ndizosavuta komanso zotsika mtengo.
