Yuav ua li cas txias kos round bar tsim

Raw Khoom Xaiv thiab Kev Npaj

Kev tsim cov khaub thuas rub puag ncig bar pib nrog nruj raw khoom xaiv. High- zoo steel billets los yog kub- dov puag ncig bar yog xaiv los ua cov khoom siv hauv paus, vim tias lawv cov tshuaj muaj pes tsawg leeg thiab cov qauv pib ncaj qha cuam tshuam rau qhov kawg ntawm qhov txias txias puag ncig bar. Cov khoom siv raw uas tau xaiv tau raug ntxuav ua ntej kom tshem tawm cov impurities, xeb, thiab roj stains, kom tsis txhob muaj kab mob cuam tshuam nrog cov txheej txheem tom ntej.

Pretreatment ntawm raw khoom

Tom qab kev npaj, cov ntaub ntawv raw mus los ntawm pretreatment. Cov theem no feem ntau muaj xws li annealing, uas kho cov qauv ntawm cov hlau los txhim kho nws cov ductility thiab txo hardness, ua rau nws yooj yim rau kos. Qhov saum npoo ntawm cov khoom yog tom qab ntawd kho nrog pickling lossis txhaj tshuaj blasting kom tshem tawm cov nplai oxide ntxiv, ua raws li cov txheej txheem lubrication. Kev lubrication zoo tsim cov yeeb yaj kiab tiv thaiv ntawm qhov chaw, txo kev sib txhuam ntawm cov khoom thiab cov tuag thaum lub sij hawm kos duab.

Txias Drawing txheej txheem ua

Cov kauj ruam tseem ceeb hauv kev tsim cov khaub thuas kos puag ncig bar yog cov txheej txheem kos duab txias nws tus kheej. Pretreated raw khoom yog rub los ntawm ib tug tshwj xeeb tsim tuag nyob rau hauv chav tsev kub. Tus tuag lub puab txoj kab uas hla yog qhov xav tau loj ntawm qhov kawg txias kos puag ncig bar. Nyob rau hauv lub zog rub, cov khoom yog deformed, nws tus ntoo khaub lig -sectional cheeb tsam yog txo, thiab nws yuav siv sij hawm nyob rau hauv lub round puab txhais los ntawm cov tuag. Cov txheej txheem no txhim kho cov khoom siv kho tshuab los ntawm kev ua haujlwm hardening.

Ncej -Drawing Straightening thiab Trimming
Tom qab cov txheej txheem kos duab txias, qhov tsim txias rub tawm puag ncig yuav muaj me ntsis khoov lossis ntev ntev. Yog li ntawd nws undergoes straightening los xyuas kom meej linearity zoo, uas yog ib qho tseem ceeb rau kev siv tom ntej. Tom qab ntawd, lub bar yog txiav mus rau qhov ntev yuav tsum tau raws li cov qauv tshwj xeeb. Cov theem no tseem suav nrog tshem tawm cov burrs lossis qhov tsis sib xws ntawm qhov kawg los txhim kho cov khoom lag luam tag nrho.
Kev soj ntsuam zoo kawg thiab ntim khoom

Cov kauj ruam kawg yog kev soj ntsuam zoo ntawm qhov txias rub puag ncig bar. Cov neeg soj ntsuam xyuas nws qhov tseeb qhov tseeb, qhov chaw tiav, thiab cov khoom siv kho tshuab kom ua raws li cov lus qhia tshwj xeeb. Tsuas yog cov khoom uas dhau tag nrho cov kev kuaj xyuas yog ntim. Kev ntim khoom kom zoo tiv thaiv qhov txias rub tawm puag ncig los ntawm kev puas tsuaj lossis kev sib kis thaum lub sijhawm khaws cia thiab kev thauj mus los, kom ntseeg tau tias nws ncav cuag cov neeg siv khoom zoo.
