Cov txheej txheem tsim cov duab kos yog ib txoj hauv kev ntawm shaping qhov chaw los ntawm rub lossis ncab cov khoom los ntawm kev tuag.Cov txheej txheem pib nrog ib tug cylindrical billet, uas yog txo nyob rau hauv loj thiab ces shaped mus rau hauv cov khoom xav tau.
Cov txheej txheem kos duab ua haujlwm li cas?
Tag nrho cov txheej txheem kos duab ua haujlwm ntawm tib txoj cai.Nws txoj haujlwm tuaj yeem raug sau tseg raws li hauv qab no:
1. Cua sov
Thawj kauj ruam hauv kev kos duab yog kom sov cov hlau mus rau qhov kub thiab txias.Qhov ntsuas kub no yog "kev kos duab kub" thiab tseem ceeb heev rau kev ua tiav cov yas deformation tsim nyog.
2. Thauj khoom rau hauv Drawbench
Tom ntej no, cov hlau rhuab yog loaded rau hauv ib tug drawbench, uas muaj ib tug series ntawm tuag thiab ib tug rub mechanism.Cov hlau yog positioned kom ib kawg yog nyob rau hauv kev sib cuag nrog thawj tuag thiab lwm yam yog txuas mus rau lub rub mechanism.
3. Kev ntxuav los ntawm tus neeg ua kua qaub
Tom ntej no, cov hlau rhuab yog ntxuav los ntawm tus neeg sawv cev acid hu ua acid pickling.Cov txheej txheem no ua kom cov hlau tsis muaj plua plav, kev sib tsoo thiab lwm yam impurities.
4. Npaj nrog Lubricant Solutions
Tom qab ntawd cov hlau yog coated nrog ib tug lubricant tov, feem ntau sulling, phosphating, thiab liming.Sulling yog txheej txheej nrog ferrous hydroxide.Ib yam li ntawd, Phosphate collating yog siv rau cov hlau hauv qab phosphating.Roj thiab roj yog siv rau hlau kos duab, thiab xab npum rau daim duab qhuav.
5. Kos Duab Los Ntawm Kev Tuag
Lub tshuab rub tawm yog qhib, siv lub zog tensile rau cov hlau.Raws li cov hlau yog rub los ntawm thawj qhov tuag, nws raug txo nyob rau hauv qhov chaw hla ntu thiab elongated.Cov hlau yog ces kos los ntawm cov tuag tom ntej, txhua tus uas muaj txoj kab uas hla me dua qhov tuag dhau los.Tus naj npawb ntawm cov tuag thiab lawv qhov tshwj xeeb qhov ntev yuav nyob ntawm qhov khoom kawg.
6. Cua txias
Tom qab tau kos los ntawm qhov kawg tuag, cov hlau tau txias sai heev los ntawm huab cua, dej, lossis roj, nyob ntawm seb cov khoom siv thiab cov khoom xav tau kawg.Cov kauj ruam ua kom txias stabilizes cov khoom qhov ntev thiab tiv thaiv
Qhov zoo ntawm Drawing Manufacturing Process
Cov txheej txheem tsim cov duab kos tuaj yeem muaj ntau yam zoo.Nov yog qee qhov ntawm lawv:
1. Precision
Kev kos duab muab siab precision thiab raug cov duab.Cov khoom tsim los ntawm kev kos duab muaj lub siab ntev thiab qhov ntev ntev uas tseem ceeb rau kev siv hauv kev lag luam.Cov txheej txheem tseem tuaj yeem tsim cov khoom nrog cov duab nyuaj, xws li cov uas muaj ntau lub lobes.
2. Tus nqi tsim nyog
Kev kos duab yog tus nqi ntau dua li lwm cov txheej txheem tsim khoom rau cov khoom me me rau nruab nrab.Tag nrho cov txheej txheem sib sib zog nqus nqus tau tuaj yeem siv tau, ua kom yooj yim los tsim kom muaj nuj nqis hauv ntau txhiab thiab ntau lab.Yog li, tus nqi ib feem yog meagre.
3. Ua kom muaj zog ntxiv
Cov txheej txheem kev kos duab tuaj yeem ua haujlwm tsis siv neeg, nce kev tsim khoom thiab txo lub sijhawm ntau lawm.Automated drawing presses tuaj yeem tsim qhov chaw sai dua li cov txheej txheem ntawm phau ntawv.
4. Txhim kho nto tiav
Cov txheej txheem tuaj yeem tsim cov npoo du, polished zoo tagnrho rau cov khoom uas xav tau qib siab ntawm kev ua tiav lossis qhov zoo.
5. Txhim kho lub zog
Cov txheej txheem kev kos duab tuaj yeem ua rau cov khoom muaj zog thiab hardness, ua rau nws ruaj khov thiab tsis muaj corrosion.Qhov no yog vim hais tias kev kos duab yuav ncab cov khoom, uas aligns cov molecules thiab ua rau lawv harden, ua rau cov khoom muaj zog.
