Kev tiv thaiv kev tiv thaiv kev tawg ntawm tus kheej drilling screws
Kev puas tsuaj rau lub hau tawg, tawg tus Tsov tus tw, tus pas nrig tawg, feem ntau tshwm sim nyob rau hauv martensitic carbon steel nws tus kheej drilling ntsia hlau, martensitic carbon steel nws tus kheej drilling ntsia hlau los ntawm kub carbonitriding nto hardness mus txog ≥560HV, muaj zog nkag mus, tab sis kuj nce lub brittleness ntawm cov ntsia hlau. Thaum tus kheej drilling ntsia hlau nyob rau hauv cov ntaub ntawv ntawm ntau load, ntau torque, yooj yim vibration yuav tshwm sim brittle fracture phenomenon.Thaum tus kheej drilling lov, nws yuav tsis tsuas cuam tshuam rau kev tsim kho, tsis zoo nkauj, tab sis kuj coj ib tug series ntawm kev nyab xeeb kev nyab xeeb. Feem ntau yog cov hauv qab no los tiv thaiv kev tawg ntawm drilling ntsia hlau:
1: Xaiv cov khoom tsim nyog
a: Ua ntej siv, paub meej tias cov khoom siv kho tshuab puas tuaj yeem ua tau raws li qhov yuav tsum tau siv
b: Tsim nyog xaiv ntawm cov ntsia hlau loj thiab ntev
C: Nws raug nquahu kom siv ib nrab hniav los yog ob tug hniav khoom hauv interlayer ib puag ncig
2: Siv tus lej
A: Siv 4-6 screws ib square meter
B: Tus naj npawb ntawm lub ru tsev thiab lub phaj hnyav yuav tsum tau nce kom tsim nyog
C: Cua cheeb tsam yog qhov loj dua tsim nyog nce ntau npaum
3: Txoj kev siv kom raug
A: Coj mus rhaub perpendicular rau axis ntawm cov xov, tsis txhob qaij
B: Hauv cov txheej txheem nruj, lub zog yuav tsum tsis sib xws, thiab lub zog nruj yuav tsum tsis txhob dhau qhov kev nyab xeeb torque
C: 12 #, 14 # specification khoom, hluav taws xob xyaum ceev 1000-1800 kiv puag ncig tsis tuaj yeem ceev heev
4: Ua tsis tiav torque (cov ntaub ntawv hauv qab no rau kev siv nkaus xwb) chav tsev:Nm
