Dab tsi yog cov ntsiab cai ntawm high-frequency hardening tshuab?

(1) Cov hauv paus ntsiab lus

Muab lub workpiece tso rau hauv lub qhov txhab inductor nrog lub hollow tooj liab raj. Tom qab dhau los ntawm qhov nruab nrab zaus lossis siab zaus hloov pauv tam sim no, qhov cuam tshuam tam sim no ntawm tib zaus yog tsim rau ntawm qhov chaw ntawm lub workpiece, thiab qhov saum npoo los yog ib feem ntawm qhov yog rhuab sai heev (qhov kub tuaj yeem nce hauv ob peb feeb) 800 ～ 1000 ℃, cov tub ntxhais tseem nyob ze rau hauv chav tsev kub) Tom qab ob peb feeb, tshuaj tsuag (immersion) dej txias (los yog tshuaj tsuag immersion roj txias) sai sai thiab tam sim ntawd ua kom tiav cov immersion ua hauj lwm, kom cov nto los yog ib feem ntawm lub workpiece tuaj yeem ntsib qhov sib thooj hardness yuav tsum tau.

(2) Kev xaiv cov cua sov zaus

Nyob rau hauv chav tsev kub, kev sib raug zoo ntawm qhov tob δ (mm) ntawm induced tam sim no ntws mus rau hauv lub workpiece nto thiab qhov zaus tam sim no f (HZ) yog tias qhov zaus nce, qhov tam sim no nkag mus tob, thiab hardening txheej yuav txo.

Feem ntau siv tam sim no frequencies yog:

1. Cov cua kub ntau zaus: 100 ~ 500KHZ, feem ntau siv 200 ~ 300KHZ, nws yog hluav taws xob raj hom cua sov zaus, lub hardening txheej tob yog 0.5 ~ 2.5 hli, haum rau me me thiab nruab nrab qhov chaw.

2. Qhov nruab nrab zaus cua sov: qhov zaus tam sim no yog 500 ~ 10000HZ, feem ntau yog 2500 ~ 8000HZ, cov khoom siv hluav taws xob yog cov khoom siv hluav taws xob nruab nrab zaus cua sov lossis silicon tswj nruab nrab zaus generator. Qhov tob ntawm txheej hardened yog 2 ~ 10 mm. Haum rau txoj kab uas hla loj, nruab nrab thiab loj zog, thiab lwm yam 3. Fais fab zaus cua sov: qhov zaus tam sim no yog 50HZ. Siv cov khoom siv hluav taws xob hluav taws xob ntau zaus cua sov, qhov tob ntawm txheej tawv tuaj yeem ncav cuag 10-20mm, uas yog tsim rau nto quenching ntawm loj-inch workpieces.
