Musiyano uripo pakati pehigh frequency uye medium frequency quenching in yakakwira frequency kudzima michina

(1) High-frequency quenching ine isina kudzika yakaomeswa layer (1.5 ~ 2mm), yakanyanya kuomarara, iyo workpiece haisi nyore kuisa oxidize, ine diki deformation, yakanaka quenching mhando uye yakakwirira kugadzirwa kwehunyanzvi, uye inokodzera zvikamu zvinoshanda pasi pekukakavara. mamiriro, akadai kazhinji magiya madiki, Shafts (midziyo inoshandiswa ndeye 45 # simbi, 40Cr);

(2) Iyo yakaomeswa dhizaini yepakati frequency quenching yakadzika (3 ~ 5mm), iyo inokodzera zvikamu zviri pasi pekumonyoroka uye kumanikidzwa mitoro, senge crankshafts, magiya mahombe, ekukuya muchina maspindle, nezvimwewo (zvinhu zvinoshandiswa 45 # simbi, 40Cr, 9Mn2V uye ductile iron).

(3) High frequency induction heat 200～1000kHz 0.5～2.5 Diki nepakati modulus magiya uye shaft zvikamu zvepakati uye diki saizi.

(4) Yepakati frequency induction kudziyisa 2500～8000Hz 2～10 Mahombe shafts uye makuru uye epakati modulus magiya.

Zvinoenderana neazvino frequency, induction yekudziya yekudzima kwepamusoro inogona kukamurwa kuita: yakakwira frequency quenching 100-1000kHz. Yepakati frequency inodzima 1-10kHz. Simba frequency kudzima 50Hz.

1. Kuomarara kwemupendero wepasi ndeye 2-3HRC yakakwira kupfuura iyo yekudzima zvakajairika, uye ine kuderera kwebrittleness, kuneta simba, uye kukanganisa kuoma. Kazhinji, workpiece inogona kuwedzerwa ne 20-30%.

2. Iyo deformation idiki, uye kudzika kwekudzimisa layer kuri nyore kudzora.

3. Yakachipa yakaderera yakaderera kuomarara simbi inogona kushandiswa, iko kushanda kuri nyore kuona mechanization uye otomatiki, kubereka kwakakwira, kukwirisa kwazvino frequency, kutetepa kwayo kuomarara layer.

(5) High frequency quenching midziyo inowanzoita 1-2mm, yepakati frequency quenching inowanzoita 3-5mm, uye simba frequency quenching inogona kusvika>=10-15mm.

(6) High-frequency induction heat: iyo yazvino frequency ndeye 100-500 kHz (kHz), uye iyo inoshanda kuomesa kudzika ndeye 0.5-2 mm (mm). Iyo inonyanya kushandiswa kune zvidiki uye zvepakati-saizi zvikamu zvinoda yakatetepa yakaomeswa layer, senge madiki Modular magiya, madiki uye epakati shafts, nezvimwe.

(7) Yepakati frequency induction heat: iyo frequency yazvino i500 kusvika 10000 Hz (Hz), uye kudzika kunoshanda kuomesa ndeye 2 kusvika 10 mm (mm). Inonyanya kushandiswa kune zvikamu zvinoda yakadzika yakaomeswa layer, senge magiya ane epakati modulus, Mahombe module magiya, shafts ane madhayamita akakura, nezvimwe.
