Njira zopewera kusinthika kwa macheka ozungulira pogwiritsa ntchito makina owumitsa kwambiri komanso njira zowongolera
Njira zopewera kusinthika kwa macheka ozungulira makina owumitsa pafupipafupi kwambiri kuzimitsa ndi njira zolezera
1. Bolodi la macheka liyenera kulowa m’malo ozizira molunjika panthawi yozimitsa, kuti malekezero onse a bolodi azitha kukhazikika nthawi imodzi. Mafuta akagwiritsidwa ntchito ngati njira yozimitsira kuziziritsa, ndikwabwino kuwongolera pa 60-90 ° C. Ngati kutentha kwamafuta kuli kotsika kuposa 50 ℃, kusinthika kwa bolodi kumawonjezeka, ndipo pamakhala chiwopsezo chozimitsa ming’alu. Kuti muchepetse kupsinjika, kutsitsa kapena kutsitsa kumatha kugwiritsidwa ntchito.
2. Pansi pa malo owonetsetsa kuumitsa, njira yowotchera magetsi imatengedwa kuti kuchepetsa mphamvu ya mafunde a electromagnetic pa workpiece.
3. Pamene kusanja kumalephera kukwaniritsa zofunikira pambuyo pa kusintha kwa magawo awiri, mungagwiritse ntchito nyundo yozizira kuti muyike, koma teknoloji yopangira nyundo imakhala yovuta kwambiri, ndipo kusinthika kumawonjezeka ngati sikuli kolondola.
4. The Ms point ya 65Mn chitsulo ndi pafupifupi 270 ℃. Pamene kusintha kwa martensitic kumachitika, pulasitiki yachitsulo imakhala yabwino kwambiri. Ngati bolodi la macheka liyikidwa pakati pa mbale ziwiri panthawiyi, likhoza kukakamizidwa kuti likhale lofanana.
5. Njira yosinthira gawo yomwe imachitika pamene bolodi la macheka likutenthedwa lingagwiritsidwe ntchito kupititsa patsogolo. Tsukani pamwamba pa tsamba la macheka musanayambe kutentha kuti muchepetse zolakwika zomwe zasonkhanitsidwa panthawi ya stacking. Kutentha kuyenera kupanikizidwa ndi mbale yosalala ndipo nthawi yotentha iyenera kukhala yokwanira.
6. Kutentha kwa kutentha kuyenera kutenga malire apamwamba, ndipo nthawi yotentha iyenera kukhala yokwanira kukhazikika mkati mwa bolodi la macheka, kuchepetsa Ms point, kuonjezera kuchuluka kwa austenite yosungidwa pambuyo pozimitsa, ndi kuchepetsa kusinthika kwa bolodi. .
