Ndeupi mutsauko pakati yakakwira frequency kudzima uye yepakati frequency quenching?

Nheyo yekushanda yekudzima kwepamusoro-frequency quenching uye yepakati-frequency quenching yakafanana neiyo yekupisa induction: ndiko kuti, workpiece inoiswa muinductor, uye inductor kazhinji igomba remhangura chubhu inopinza yepakati frequency kana yakakwirira frequency alternating ikozvino. (1000-300000Hz kana kupfuura). Iyo inotsinhanisa magineti inogadzira iyo induced ikozvino yeakawanda frequency mune workpiece. Kugoverwa kweiyi induced ikozvino mu workpiece haina kuenzana, yakasimba pamusoro pepamusoro, asi yakanyanya kusimba mukati, uye iri pedyo ne0 pakati. Iyi ganda rinoshandiswa rinoshandiswa. , pamusoro pebasa rekushanda rinogona kupisa nokukurumidza, kutonhora kwepamusoro kunokwira kusvika 800-1000 ℃ mumasekondi mashomanana, uye kutonhora kwechikamu chepakati iduku zvikuru.

Nekudaro, panguva yekupisa, kugoverwa kweiyo induced ikozvino muworkpiece haina kuenzana, uye kupisa kunogadzirwa neazvino mafrequencies akasiyana zvakare. Zvadaro, mutsauko pakati pe-high-frequency quenching uye yepakati-frequency quenching inouya:

1. High frequency quenching

Ikozvino frequency pakati pe100 ne500 kHz

Kudzika kwakaomeswa layer (1.5 ~ 2mm)

Zvakanakira mushure mekudzimisa frequency: kuomarara kwakanyanya, iyo workpiece haisi nyore kuve oxidized, iyo deformation idiki, yekudzima mhando yakanaka, uye kugona kwekugadzira kwakakwira.

High-frequency quenching inokodzera zvikamu zvinoshanda pasi pekukwesha, senge magiya madiki uye shafts (zvinhu zvinoshandiswa 45# simbi, 40Cr)

2. Intermediate frequency quenching

Ikozvino frequency ndeye 500 ~ 10000 Hz

Iyo yakaomeswa layer yakadzika (3 ~ 5mm)

Yepakati frequency quenching inokodzera zvikamu zviri pasi pekumonyorora uye kumanikidzwa mitoro, senge crankshafts, magiya mahombe, kugaya muchina spindles, nezvimwewo (zvinhu zvinoshandiswa 45 # simbi, 40Cr, 9Mn2V uye ductile graphite.

Muchidimbu, imwe yemisiyano iri pachena pakati pekudzima kwepamusoro-frequency quenching uye yepakati-frequency quenching ndiyo mutsauko mukupisa kwekupisa. High-frequency quenching inogona kuomesa pasi munguva pfupi, chimiro chekristaro chakanyanya kunaka, uye deformation yemaitiro idiki. Iva mudiki.
