Hluav taws xob hexagonal laum tail nrog ncoo nws tus kheej tapping galvanized dovetail ntsia hlau xim steel pobzeb ntsia thawv laum Tail rau kaum kaum laum tail ntsia hlau

Yog tias koj thawj zaug nkag siab txog cov khoom siv ntawm cov ntsia hlau thaum siv lawv, ces koj tuaj yeem siv tau zoo dua. Ntau hom screws muaj cov khoom sib txawv, thiab cov khoom sib txawv ntawm cov khoom siv sib txawv ua rau ntau lub sijhawm uas siv cov ntsia hlau. 1, Self tapping screws: Mechanical kev ua tau zoo yuav tsum tau 1. Core hardness: tus qauv nqi HRC28-38. Thaum kuaj, coj ib ntu 1-2 zaug ntawm nominal txoj kab uas hla ntawm tus Tsov tus tw. Yog hais tias lub nominal ntev luv luv, nws yuav tsum tau embedded ua ntej thiab ces lub hardness yuav ntsuas. 2. Nto hardness: Txheem MIN HV450. 3. Carbonized txheej: Standard 4 # -6 #: 0.05-0.18mm, 8 # -12 #: 0.10-0.23mm, 14 #: 0.13-0.28mm. Lub hom phiaj tseem ceeb ntawm carburization yog txhawm rau txhim kho qhov tawv tawv thiab ua kom lub zog ntawm cov hniav. Yog tias qhov decarburization tob dhau lawm thiab cov carburization tsis txaus, lub zog ntawm cov hniav yuav tsis ua raws li qhov yuav tsum tau ua, uas txhais tau hais tias cov hniav yuav puas thaum lub sij hawm ntsia hlau. 4. Torque: Standard specifications 4 # 5 # 6 # 7 # 8 # 10 # 12 # 14 # A cov hniav 14212835455696145AB hniav 142128354565102165. 5. Screw nyob rau hauv kev sim: Ntsia hlau rau hauv lub steel phaj tapping ntsia hlau. Tus kheej tapping ntsia hlau yuav tsum tsim cov xov sib txuam hauv daim ntawv xeem, thiab cov xov ntawm cov ntsia hlau nws tus kheej yuav tsum tsis txhob deform los yog puas mus txog rau thaum kawg taper xov tag dhau los ntawm cov phaj xeem. Cov ntsia hlau hauv kev sim tsuas yog siv tau rau tus kheej tapping screws ntawm hom AB, B, BP, thiab lwm yam. Raws li IFI cov kev cai, cov phaj xeem yuav tsum tau npaj los ntawm ib qho nyuaj-carbon txias-dov hlau nrog Rockwell hardness ntawm 70-85HRB. Cov txheej txheem tshwj xeeb rau cov hlau phaj, nrog rau cov tuab, muaj nyob hauv cov lus hauv qab no. Qhov ntsuas qhov yuav tsum tau xuas nrig ntaus los yog drilled, nrog ib tug kam rau ua ntawm ± 0.025mm rau cov teev nominal txoj kab uas hla (saib cov lus hauv qab no). Specification 6 # 7 # 8 # 10 # 12 # 1/4 xeem phaj thickness (mm) 1.85-1.953.12-3.234.68-4.84 aperture (mm) ± 0.0252.953.263.454.044.765.50.
