Cold-draw tube yog lub raj hlau uas raug tsim los ntawm cov txheej txheem kos duab txias. Nws nta siab qhov tseeb, zoo heev nto tiav, thiab superior mechanical zog. Nws yog dav siv nyob rau hauv machinery manufacturing, automotive kev lag luam, aerospace, thiab lwm yam teb. Nws txoj kev tsim khoom feem ntau suav nrog cov kauj ruam tseem ceeb xws li kev npaj lub raj khoob, lubrication, kos duab txias, thiab kev kho cua sov.
Ua ntej, kev npaj tube dawb paug yog ib kauj ruam tseem ceeb hauv kev ua kom txias - rub tube ntau lawm. Tube blanks feem ntau yog kub- dov seamless los yog welded steel kav thiab tau ua tib zoo tshuaj xyuas kom ntseeg tau tias lawv cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom raws li cov kev cai. Qhov loj thiab qhov zoo ntawm lub raj blanks ncaj qha cuam tshuam rau cov txheej txheem kev kos duab txias tom ntej. Yog li ntawd, lub raj blanks yuav tsum tau ncaj, txiav, thiab ntxuav kom tshem tawm cov nplai thiab qhov tsis xws luag los xyuas kom meej tias cov txheej txheem txias txias.
Qhov thib ob, lubrication yog ib kauj ruam tseem ceeb hauv kev kos duab txias. Vim tias kev sib txhuam ntawm cov hlau thiab cov tuag thaum lub caij txias txias yog qhov siab, nws tuaj yeem ua rau lub raj ntog los yog ua rau tuag. Yog li ntawd, ib tug siab - lubricant efficiency yuav tsum tau siv rau lub raj dawb paug nto. Cov txheej txheem lubrication muaj xws li phosphating thiab saponification, graphite txheej, los yog tshwj xeeb lubricating coatings los txo kev sib txhuam, txhim kho qhov txias txias efficiency, thiab txhim kho qhov zoo ntawm lub raj.
Tom qab ntawd los rau theem kev kos duab txias. Kev kos duab txias yog rub lub raj dawb paug los ntawm kev tuag tapered, txo nws cov ntoo khaub lig-section thiab ua kom nws ntev kom ua tiav qhov ntev thiab zoo. Thaum lub sij hawm txias txias txheej txheem, lub raj tau txais cov yas deformation ntawm chav tsev kub, uas ua rau cov nplej refinement thiab kev txhim kho tseem ceeb hauv cov khoom siv kho tshuab. Kev kos duab txias tuaj yeem ua tau hauv ib qho lossis ntau qhov kev hla. Cov txheej txheem tshwj xeeb, xws li kev nrawm nrawm, tuag taper, thiab lubrication tej yam kev mob, yuav tsum tau kho raws li cov khoom siv raj thiab specifications.
Thaum kawg, txias-cov hlab ntsha feem ntau raug kho cua sov kom tshem tawm kev ua haujlwm nyuaj, txhim kho microstructure, thiab kho cov khoom siv kho tshuab. Cov kev kho cua sov feem ntau muaj xws li annealing thiab normalizing. Los ntawm kev tswj cov cua kub thiab txias tus nqi, lub raj ua tiav qhov xav tau lub zog, toughness, thiab ductility. Hauv cov ntsiab lus, txoj kev sib xyaw ua ke ntawm qhov txias txias - cov raj kos muaj ntau qhov txuas xws li cov raj khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob Los ntawm kev tswj cov txheej txheem meej, siab -kev ua tau zoo precision steel raj tuaj yeem tsim ua kom tau raws li daim ntawv thov kev xav tau ntawm cov chaw lag luam sib txawv.
