Kev ntsuas los tiv thaiv deformation ntawm ncig saws los ntawm high-frequency hardening tshuab quenching thiab leveling txoj kev

1. Lub saw board yuav tsum nkag mus rau qhov nruab nrab cua txias ntsug thaum lub sij hawm quenching, thiaj li hais tias ob qhov kawg ntawm lub saw board yog txias tib lub sij hawm. Thaum cov roj siv los ua lub quenching txias nruab nrab, nws yog feem ntau zoo dua los tswj nws ntawm 60-90 ° C. Yog tias cov roj kub qis dua 50 ℃, qhov deformation ntawm cov saw board yuav nce, thiab muaj peev xwm ntawm quenching cracking. Txhawm rau txo qhov kev ntxhov siab, kev siv tshuaj tua kab mob los yog qib quenching tuaj yeem siv.

2. Nyob rau hauv lub premise ntawm kev ruaj ntseg hardening, txoj kev ntawm lub hwj chim-tawm cua sov yog saws los txo cov kev cuam tshuam ntawm electromagnetic tsis nyob rau hauv lub workpiece.

3. Thaum lub leveling tseem ua tsis tau raws li qhov yuav tsum tau ua tom qab ob theem hloov, koj tuaj yeem siv lub rauj txias rau leveling, tab sis lub tshuab hammering yog xav tau heev, thiab qhov deformation yuav nce ntxiv yog tias nws tsis raug.

4. Ms point ntawm 65Mn steel yog hais txog 270 ℃. Thaum lub martensitic transformation tshwm sim, lub plasticity ntawm cov hlau yog zoo heev. Yog hais tias lub saw board tau muab tso rau nruab nrab ntawm ob daim hlau nyob rau lub sijhawm no, nws tuaj yeem raug yuam kom qib.

5. Cov txheej txheem hloov theem uas tshwm sim thaum cov saw board yog tempered tuaj yeem siv rau kev sib tw ntxiv. Ntxuav lub ntsej muag ntawm cov saw hniav ua ntej tempering kom txo tau qhov yuam kev ntau ntxiv thaum lub sij hawm stacking. Lub tempering yuav tsum tau nias nrog lub tiaj tiaj tiaj thiab lub sijhawm tempering yuav tsum txaus.

6. Cov cua kub cua sov yuav tsum siv lub sij hawm ua kom sov, thiab lub sij hawm cua sov yuav tsum txaus kom stabilize lub sab hauv ntawm lub saw board, txo qhov Ms point, nce tus nqi ntawm cov austenite tuav tom qab quenching, thiab txo cov deformation ntawm saw board. .
