Cov kav dej txiasmuaj ntau heev nyob rau hauv kev lag luam thiab yog ib tug dav siv hom steel yeeb nkab.
Cov kav dej txias txias yog tsim los ntawm cov kav dej kub dov, thiab kev xaiv cov khoom siv, cov lus qhia tshwj xeeb, thiab qhov zoo ntawm cov kav dej kub dov ncaj qha cuam tshuam rau cov txheej txheem kos duab thiab cov khoom tiav.Thaum xaiv cov khoom, cov ntsiab lus hauv qab no yuav tsum raug sau tseg:
(1) Thaum xaiv cov ntaub ntawv, cov ntaub ntawv uas tsis tshua muaj hardness thiab zoo plasticity feem ntau xaiv thaum ua kom muaj zog;
(2) Cov kev qhia tshwj xeeb ntawm cov kav hlau steel yuav tsum raug xaiv raws li qhov tshwj xeeb ntawm cov khoom tiav, kom ntseeg tau tias lawv cov elongation nyob nruab nrab ntawm 20% thiab 40%;Yog tias qhov elongation me dhau lawm, lub zog saum npoo ntawm cov khoom tiav tsis tuaj yeem lav, thiab yog tias nws loj dhau, nws ua rau nws nyuaj rau kev ua tiav cov txheej txheem kos duab;
(3) Qhov saum npoo ntawm cov khoom yuav tsum tsis txhob muaj qhov tsis xws luag xws li qhov pits, tawg, tawg, folds, nti, ellipses, thiab lwm yam;
(4) Nws raug nquahu kom xaiv cov kav hlau uas tau kub dov thiab muab tso rau 0.5-2a.Yog tias lub sijhawm luv luv, qhov xeb ntawm cov kav hlau yuav tsum ntiav, thiab yog tias lub sijhawm ntev dhau lawm, qhov xeb ntawm cov kav hlau yuav tob dhau.Cov no tuaj yeem ua rau tsis txaus kho ua ntej ntawm cov yeeb nkab steel nto, yog li cuam tshuam rau qhov zoo ntawm cov khoom tiav.
Cov kav hlau uas tsis tau ua tiav tsis tuaj yeem rub tawm thaum lub caij txias txias vim muaj kev sib txhuam coefficient ntau dhau ntawm cov yeeb nkab steel thiab pwm;Tsuas yog los ntawm cov txheej txheem ua ntej kev kho mob, cov yeeb nkab hlau tuaj yeem xeb tawm ua ntej, thiab dhau los ntawm phosphating, saponification, thiab lwm yam kev kho mob, cov ntaub so ntswg hlau nplaum yog tsim rau ntawm nws sab hauv thiab sab nrauv kom tsis txhob muaj kev sib txhuam ntawm cov yeeb nkab steel thiab pwm. , yog li ua kom muaj kev vam meej ntawm kev kos duab.Nyob rau tib lub sijhawm, kev kho mob ua ntej tuaj yeem txo qhov poob ntawm cov pwm, txhim kho cov txiaj ntsig thiab kev ua haujlwm zoo, thiab ua kom cov khoom tiav ntawm cov khoom lag luam du thiab zoo ib yam, nrog kev tiv thaiv xeb zoo.
Cov ntsiab lus hauv qab no yuav tsum raug sau tseg hauv kev kho ua ntej ntawm cov kav dej steel:
(1) Acid tu thiab tshem tawm xeb yuav tsum tau ua tib zoo.Thaum twg cov xeb uas tsis tau muab tshem tawm tau pom, nws yuav tsum tau muab rov qab.
(2) Thaum lub sij hawm tsim khoom, qhov muaj pes tsawg leeg ntawm cov tshuaj phosphating thiab saponification tov yuav tsum tau kuaj tsis tu ncua los xyuas kom meej cov khoom ntsuas ntawm cov tshuaj phosphating thiab saponification tov.Yog tias qhov ntsuas tsis tau ua tiav, kev sib xyaw ua ke yuav tsum tau ua raws sijhawm.
(3) nruj me ntsis tswj qhov kub thiab txias lub sij hawm ua hauj lwm ntawm kev kho cov tshuaj.
Cov kav dej txias txias yog tsim los ntawm kev kos cov duab thiab cov pwm loj nyob rau hauv qhov kev txiav txim ntawm lub zog, thiab qhov tseeb qhov tseeb thiab qhov zoo ntawm cov pwm ncaj qha cuam tshuam rau qhov raug thiab qhov zoo ntawm cov khoom tiav.
Pwm tsim yuav tsum xyuam xim rau cov hauv qab no:
(1) Kev txiav txim siab ntawm cov pwm sab hauv thiab sab nraud yuav tsum xav txog cov nyiaj rov qab ntawm cov khoom tiav tom qab kos duab txias.Feem ntau, cov ntaub ntawv uas tsis tshua muaj hardness thiab me me deformation muaj ib tug me me rebound tus nqi, thaum cov ntaub ntawv uas siab hardness thiab loj deformation muaj ib tug loj rebound tus nqi;
(2) Qhov saum npoo ntawm cov pwm yuav tsum muaj qhov xav tau qis dua, feem ntau yog ib mus rau ob theem qis dua cov khoom tiav;
(3) Cov khoom siv pwm yog ua los ntawm cov khoom siv muaj zog thiab hnav-resistant.
Tshiab Gapower hlauyog tus kws tshaj lij steel yeeb nkab chaw tsim khoom, qhov loj ntawm OD6mm txog 273mm, thickness yog los ntawm 0.5mm mus rau 35mm.Cov qib steel tuaj yeem yog ST35 ST37 ST44 ST52 42CRMO4, S45C CK45 SAE4130 SAE4140 SCM440 thiab lwm yam. Zoo siab txais tos cov neeg siv khoom nug thiab tuaj xyuas lub Hoobkas.
