Ua ntej txias forging ntawm bolts

Loj steel hlau yuav tsum tau uncoiled thiab txiav mus rau ib tug ntev ntev. Raws li cov kev cai ntawm ISO 898-1, cov qib steel ntawm tag nrho cov kev lag luam yog tus qauv. Tom qab ntawd, siv cov cuab yeej tshwj xeeb kom txias forge steel hlau rau hauv qhov tseeb. Hlau yog qhov tseem ceeb stamped thiab tsim nyob rau hauv ib lub pwm los ntawm ib tug series ntawm compression pwm ntawm chav tsev kub thiab siab siab. Cov pwm nws tus kheej yuav yog qhov nyuaj heev, muaj txog li 200 qhov sib txawv nrog kev ua siab ntev ntawm ob peb feem pua ​​millimeters. Thaum ua tiav, txias forging tuaj yeem ua kom ceev ceev, loj-scale, thiab ua kom zoo ib yam ntawm cov bolts.
Rau txoj kev tsim cov ntsia liaj qhov rooj uas tsis tuaj yeem tsim los ntawm qhov txias forging, ntxiv cov txheej txheem tig los yog drilling yuav tsum tau ua. Tig yog siv cov kev kub ceev rotating bolts los txiav steel kom ua tau raws li qhov xav tau thiab tsim. Drilling yog txheej txheem ntawm xuas nrig ntaus qhov hauv bolts. Yog tias xav tau los ntawm kev tsim, qee qhov bolts kuj tseem muaj cov tshuab ntxhua khaub ncaws ntxiv rau theem no.
