Kufotokozera kwa Ntchito Makina Otenthetsera Okwera Kwambiri mu Surface Quenching of Metal Workpieces

Makina otenthetsera otenthetsera okwera kwambiri amagwiritsidwa ntchito kwambiri kuzimitsa zitsulo zachitsulo, monga kuzimitsa ndi kuumitsa mutu wa kubowola, kuzimitsa magiya a mano, kuzimitsa kutentha kwapagalimoto pamalumikizidwe apadziko lonse lapansi, ma crankshafts, zomangira, etc. . Tsopano tiyeni tifotokoze mwachidule njira yoyambira yozimitsa pamwamba. Tikayika chitsulo chopangira chitsulo pabalaza la inductor ndi chubu chamkuwa chopanda pake cha makina otenthetsera otenthetsera kwambiri, titatha kudutsa maginito osinthasintha apano, kutentha kwanthawi yayitali komweko kumapangidwa mwachangu pamwamba pa maginito. workpiece. Pamwamba pa gawo ndi mkangano mofulumira, pamwamba pa workpiece akhoza usavutike mtima ndi madigiri 800 mpaka 1000 mu masekondi pang’ono, ndi chapakati pa workpiece akadali pafupi ndi kutentha m’nyumba, ndiyeno nthawi yomweyo utsi madzi ozizira. kapena kumiza workpiece mu quenching mafuta kuziziritsa, kotero kuti pamwamba wosanjikiza workpiece kufika ankafuna quenching kuuma.

Kwa nthawi yaitali, pamwamba quenching ndondomeko zitsulo workpieces, tidakali ndi njira zambiri zachikhalidwe ndi wamba, monga: lawi Kutentha pamwamba quenching, magetsi kukhudzana Kutentha pamwamba quenching, electrolyte Kutentha pamwamba quenching, laser Kutentha pamwamba quenching, elekitironi mtengo Kutentha. kuyeretsa pamwamba ndi zina zambiri. Komabe, njira yowumitsa kutentha kwapamwamba kwambiri imakhala ndi ubwino wake, chifukwa pakali pano imatentha kwambiri ndi kutentha kuposa njira zina, ndipo nthawi yomweyo imaphatikizidwa ndi kuzizira. Makina otenthetsera othamanga kwambiri amatha kubweretsa mwachangu pamwamba pa chogwirira ntchito kapena chitsulo ku kutentha kozimitsa, ndipo makina otenthetsera othamanga kwambiri amazizira mwachangu osadikirira kuti kutentha kufikire pakati, kuuma kokhako kumangokhala ndi martensite, ndipo likulu limakhalabe losazimitsidwa pulasitiki loyambirira, bungwe labwino lolimba (kapena lokhazikika, lokhazikika komanso lozimitsidwa ndi kupsya mtima).
