Hydraulic pas nrig, thawb-rub pas nrig quenching thiab tempering ntau lawm kab

1. Kev xav tau

1. Lub hom phiaj

Siv rau tag nrho cov cua sov thiab tempering ntawm hydraulic rods thiab laub-rub rods.
2. Cov yam ntxwv ntawm lub workpiece

1) Cov khoom siv: 45 # steel, 40Cr, 42CrMo

2) Khoom qauv (mm):

Txoj kab uas hla: 60 ≤ D ≤ 150 (khoom khov hlau)

Ntev: 2200mm ~ 6000mm;

3) Lub round steel yog rhuab mus rau lub quenching kub los ntawm nruab nrab zaus thiab ces txias rau quenching kev kho mob, thiab tempering kev kho mob yog ua on-line.

quenching cua kub: 950 ± 10 ℃;

Tempering kub: 650 ± 10 ℃;

4) Tawm tswv yim voltage: 380V ± 10%

5) Cov zis yuav tsum tau: 2T / H (txog 100mm round steel)

3. Kev xav tau rau cov cuab yeej quenching thiab tempering:

1) Tag nrho cov saum npoo hardness ntawm tag nrho cov ncej yog 22-27 degrees HRC, qhov tsawg kawg nkaus hardness yuav tsis tsawg tshaj li 22 degrees, thiab qhov tsim nyog hardness yog 24-26 degrees;

2) Lub hardness ntawm tib lub ncej yuav tsum yog uniform, hardness ntawm tib batch kuj yuav tsum uniform, thiab uniformity ntawm ib tug ncej yuav tsum nyob rau hauv 2-4 degrees.

3) Lub koom haum yuav tsum muaj kev sib xws thiab cov khoom siv tshuab ua tau raws li qhov yuav tsum tau ua:

ib. Lub zog tawm los yog ntau dua 50kgf / mm ²

b. Tensile lub zog yog ntau dua 70kgf / mm ²

c. Elongation ntau dua 17%

4) Qhov qis tshaj ntawm qhov nruab nrab ntawm lub voj voog yuav tsum tsis txhob qis dua HRC18, qhov qis tshaj ntawm 1/2R yuav tsum tsis txhob qis dua HRC20 degrees, thiab qhov qis tshaj ntawm 1/4R yuav tsum tsis txhob qis dua HRC22 degrees.

2. Workpiece specifications

Raws li qhov yuav tsum tau muaj ntawm tus neeg yuav khoom, peb muab cov khoom nram qab no ntawm cov sensors rau 45-150 round steel

Raws li lub workpiece specification lub rooj muab los ntawm tus neeg yuav khoom, tag nrho ntawm 4 teeb ntawm inductors yuav tsum tau, 4 teev txhua rau quenching thiab tempering. Qhov cua sov ntawm lub workpiece yog 40-150mm. Lub quenching kub nce sensor txais 800mm × 2 tsim, quenching uniform kub sensor txais 800mm × 1 tsim, thiab quenching kub preservation inductor txais 800mm × 1 tsim los xyuas kom meej cov cua sov. Lub tempering ib feem yog tsim nyob rau hauv tib txoj kev.

Peb, txheej txheem ntws piav qhia

Ua ntej, manually tso lub workpieces uas yuav tsum tau rhuab nyob rau hauv ib tug kab thiab ib txheej ntawm cov khoom noj racking, thiab ces cov khoom yog maj mam xa mus rau lub feeding khib los ntawm lub loading tshuab, thiab ces cov khoom raug thawb mus rau hauv cov khoom noj. inclined roller los ntawm lub tog raj kheej cua. Lub inclined roller tsav cov khoom bar rau pem hauv ntej thiab xa cov khoom mus rau quenching cua sov inductor. Tom qab ntawd lub workpiece yog rhuab los ntawm quenching cua sov ib feem, thiab quenching cua sov muab faib ua quenching cua sov cua sov thiab quenching cua sov preservation cua sov. Hauv qhov quenching thiab cua sov, 400Kw nruab nrab zaus fais fab mov yog siv los ua kom sov lub workpiece, thiab tom qab ntawd ob txheej ntawm 200Kw nruab nrab zaus fais fab mov yog siv rau kev txuag hluav taws xob thiab cua sov.

Tom qab cov cua kub ua tiav, lub workpiece yog tsav los ntawm inclined roller kom dhau los ntawm cov quenching dej tsuag nplhaib rau quenching. Tom qab quenching tiav, nws nkag mus rau lub tempering cua sov inductor rau tempering cua sov. Tempering cua sov kuj muab faib ua ob ntu: tempering cua sov thiab tempering kub preservation. Lub tshuab cua sov siv 250Kw nruab nrab zaus fais fab mov, thiab qhov chaw txuag hluav taws xob siv ob txheej ntawm 125Kw nruab nrab zaus siv hluav taws xob. Tom qab cov cua sov ua tiav, cov khoom raug tshem tawm, thiab cov txheej txheem tom ntej yog nqa tawm.
