Iyini i-High-frequency Quenching?

High-frequency quenchingisetshenziselwa kakhulu ukucisha izingxenye zensimbi zezimboni.Kuwuhlobo lwendlela yokwelashwa kokushisa kwensimbi eyenza indawo yokusebenza ikhiqize umshini othile owenziwe, ushise ngokushesha ubuso bezingxenye, bese ucisha ngokushesha.Imishini yokushisa yokungeniswa, okungukuthi, i-workpiece induction heat, ukuze kucinywe indawo. imishini.

Isimiso sokushisisa kokungeniswa:I-workpiece ifakwa emoyeni ngepayipi lethusi elingenalutho kunzwa, ngemva kokufinyelela kumafrikhwensi aphakathi nendawo noma i-high frequency alternating current (ac), eyakhiwe phezulu ne-frequency yamanje eyenziwe, indawo yokusebenza. noma ukushisa kwasendaweni okusheshayo (imizuzwana embalwa kuya emazingeni okushisa angama-800 ~ 1000 ℃, umnyombo usaseduze nezinga lokushisa legumbi) ngokushesha ngemva kwemizuzwana embalwa ngokushesha fafaza (cwilisa) ukupholisa amanzi (noma ukupholisa ukucwiliswa kwamafutha) ukucwiliswa okuphelele komsebenzi womlilo, Yenza indawo yokusebenza noma yendawo ukuze kuzuzwe izidingo zobulukhuni obuhambisanayo.

Uma kuqhathaniswa nokucisha ukushisa okujwayelekile, inakho:

1. Isivinini sokushisisa siyashesha kakhulu, esinganweba ububanzi bezinga lokushisa lokushintsha komzimba A futhi sifinyeze isikhathi soshintsho.

2. I-cryptocrystalline martensite enhle kakhulu ingatholakala ebusweni bomsebenzi ngemva kokucisha, futhi ubulukhuni buphakeme kancane (2 ~ 3HRC) .Ukuqina okuphansi namandla aphezulu okukhathala.

3. I-workpiece ephathwa ngenqubo akulula uku-oxidize kanye ne-decarbonize, futhi ngisho nezinye ze-workpiece zingahlanganiswa ngokuqondile futhi zisetshenziswe ngemva kokucubungula.

4, ungqimba oluqinile lujulile, kulula ukulawula ukusebenza, kulula ukuqaphela umshini, i-automation.

5, ukushisa kwelangabi kucime

Ukucisha imvamisa ephezulu kusetshenziswa ucezu lokusebenza oludinga ukuthwala isenzo sokushintshana komthwalo njengokugoba nokugoba.Kudinga ungqimba olungaphezulu ukuthi luthwale ukucindezeleka okuphezulu noma ukumelana nokugqoka kunomgogodla, futhi ingaphezulu le-workpiece lidinga ukuqiniswa.Ifanele insimbi enokuqukethwe kwekhabhoni We=0.40 ~ 0.50%.
