Yog vim li cas tsis tau ib txheej ntawm cov cuab yeej ua kom muaj zog ntau ua tau raws li qhov yuav tsum tau muaj ntawm ntau hom workpieces?

Piv txwv li, xws li quenching xav tau:

1. Qag tus pin qeb:

1. Lub workpiece yuav tsis tawg tom qab quenching

2. Deformation tsis tuaj yeem siab dua 0.2mm

3. Ua tau zoo nto quenching qhov tob: 1-5mm

4. Lub hardness tom qab kho yog kwv yees li: 45-50mm

5. Cov khoom tseem ceeb yog nruab nrab-carbon alloy yeeb nkab steel, cov khoom tseem ceeb yog 40Cr, 42CrMo, hardness ntawm workpiece tom qab kho yog hais txog HRC: 45-5

6. Workpiece loj: ntev 620-1476mm txoj kab uas hla: φ44-φ103mm

2. Gears

1. Qhov tob ntawm qhov quenching: 0.8-0.9mm

2. Cov khoom tseem ceeb: 45 #, 40Cr, 40CrNi, thiab lwm yam.

3. Nto hardness HRC tom qab kho: 48-53

4. Tus naj npawb ntawm cov hniav: 26, 33, 55, 60 Txoj kab uas hla ntawm qhov ntsuas lub voj voog: φ52, φ66, φ110, φ120 Modulus: 2

3. Cov kabmob

1. Qhov tob ntawm qhov quenching: 0.5-1mm

2. Cov khoom tseem ceeb: Cr14Mo4V, G20Cr2Ni4A, thiab lwm yam.

3. Nto hardness HRC tom qab kho: 61-63

4. Sab nraud txoj kab uas hla: φ50-φ120

Cov neeg siv khoom xav tau cov khoom siv quenching siab kom ua tau raws li qhov xav tau ntawm quenching saum toj no peb hom workpieces tib lub sijhawm. Qhov no tsis tuaj yeem ua tiav, feem ntau yog vim yog kev xaiv ntawm cov khoom siv hluav taws xob siab induction cua sov. Vim hais tias: qhov tob ntawm qhov tob yog 1-5 hli, peb yuav pom zoo kom xaiv lub suab nrov zaus induction cua sov lub zog nrog qhov zaus ntawm 30KHZ, thiab qhov tob ntawm qhov tob ntawm 0.8-0.9 hli yuav tsum xaiv 250KHZ high-frequency induction cua sov lub zog. mov, ib tug high-frequency induction cua sov fais fab mov tsis tuaj yeem ua tiav ob zaus, yog li nws tsis tuaj yeem ua tau raws li tag nrho cov kev xav tau quenching, ob lub high-frequency quenching cov cuab yeej yuav tsum tau los daws cov txheej txheem quenching, uas ntau tshaj tus neeg siv khoom thawj cov peev nyiaj, yog li qhov no kuj yog qhov kev txwv ntawm high-frequency induction hardening. Tsis tas li ntawd, high-frequency induction hardening tsis haum rau workpieces nrog complex duab, xws li tej yam kis tau tus mob gears. Nws yuav tsum tau hnav tsis tshua muaj siab thiab tawv cores. Tam sim no, nitriding tshuab tseem siv. Yog li ntawd, high-frequency induction hardening tsuas yog haum rau loj ntau lawm ntawm ib los yog ib tsev neeg ntawm workpieces.
