Kutentha mankhwala a masika zitsulo

Spring zitsuloakhoza kugawidwa mu kasupe otentha kupanga ndi ozizira kupanga kasupe malinga ndi njira zosiyanasiyana kupanga.

Kutentha mankhwala a thermoforming akasupe. Akasupe a thermoforming amagwiritsidwa ntchito kupanga akasupe amitundu yayikulu kapena yovuta. Kawirikawiri, kutentha kozimitsa kumaphatikizidwa ndi kupanga. Ndiko kuti, Kutentha kutentha ndi apamwamba pang'ono kuposa kutentha quenching (830 ℃ ~ 880 ℃), pambuyo Kutentha, otentha koyilo kupanga ikuchitika, ndiyeno zinyalala kutentha kuzimitsidwa, ndipo potsiriza zolimbitsa kutentha tempering ikuchitika pa 350 ℃ ~ 450 ℃, kuti apeze wokwiya tretinite dongosolo.

Pamwamba khalidwe la masika zitsulo n'kofunika kwambiri chifukwa pazipita torsional ndi kupinda maganizo. Decarburization pamwamba ndiye taboo kwambiri, kuchepetsa kwambiri kutopa mphamvu ya chitsulo. Choncho, kutentha kwa kutentha, nthawi yotentha ndi kutenthetsa sing'anga iyenera kumvetsera kusankha ndi kulamulira. Kuphatikiza apo, kuwomberedwa koyang'ana pambuyo pakutentha kumathandizanso kuthetsa zolakwika zapamtunda monga decarburization, ming'alu, inclusions ndi zolembera, ndikulimbitsa pamwamba kuti mupange kupsinjika kotsalira ndikuwonjezera kutopa kwa masika.

Kutentha mankhwala ozizira kupanga akasupe. Chitsulo chozizira chopangidwa ndi masika chimakhala choyamba pambuyo pozimitsa, kutentha kwa mankhwala, kapena kuzimitsa kwa isothermal, ndiyeno kupyolera muzithunzi zozizira kuti mutenge waya wachitsulo, ndiyeno mugwiritse ntchito waya wachitsulo ichi mwachindunji kuti mugulitse chofunika kasupe. Kasupe uyu sakhalanso wopangidwa pambuyo pozimitsa chithandizo, kokha 180 ~ 370 ℃ otsika komanso apakati kutentha kutentha, kuti athetse kupsinjika kwamkati komwe kumachitika chifukwa cha kupanga. The mtanda gawo kukula kwa mtundu uwu wa masika zitsulo ndi yaing'ono, malinga ndi quenching ndi tempering ndondomeko pamaso kupanga lagawidwa mafuta tempering zitsulo waya ndi mofulumira isothermal mankhwala ozizira kukopeka zitsulo waya. Yoyamba ndikuzimitsa mafuta + kutentha kwapakati kutentha; Yotsirizirayi imatanthawuza kusamba kutsogolera (500 ~ 550 ℃) isothermal quenching kupanga sotenite kusintha, ndiyeno kupyolera angapo ozizira kujambula kulimbitsa.

Ngati kasupe waya awiri ndi lalikulu kwambiri, monga Φ> 15mm, mbale makulidwe h> 8mm, padzakhala kuzimitsa opaque chodabwitsa, chifukwa mu kuchepetsa malire zotanuka, kutopa mphamvu, kotero kasupe zitsulo hardenability ayenera ndinazolowera m'mimba mwake zinthu masika.
