1. Cov txheej txheem ntawm kev kos duab
Cov txheej txheem kos duab hlau yog nqa tawm ntawm daim ntawv hlau sib sib zog nqus nqus tshuab. Hauv kev kos duab hlau lossis kos duab sib sib zog nqus, ib daim ntawv hlau lossis qhov khoob yog kos los ntawm kev kos duab punch. Cov xuas nrig ntaus nkag mus rau hauv qhov tuag los ua daim ntawv, uas yog cov duab kos hlau (los yog kos duab sib sib zog nqus). Feem ntau cylindrical los yog lub thawv-zoo li lub thawv yog tsim los ntawm kev kos duab lossis kos duab sib sib zog nqus, xws li cov kaus poom dej haus, qhov chaw zoo li lub thoob, qhov chaw npauj npaim, thiab lwm yam ntim thiab cov xov tooj ntawm tes ntawm ntau cov duab thiab ntau thiab tsawg. Ua piv txwv, cov txheej txheem ntws yog: sharpening → degreasing thiab xeb tshem tawm → dej ntxuav → phosphating kev kho mob → dej ntxuav → immersion nyob rau hauv lubricating kua → ziab → kos duab → straightening → txiav → oiling → ntim, thiab lwm yam.
Qhov thib ob, kev faib tawm ntawm cov txheej txheem kos duab
1. Raws li kev faib tawm ntawm daim duab lubricating cov ntaub ntawv, tuaj yeem muab faib ua daim duab qhuav thiab roj kos duab. Daim duab qhuav siv cov hmoov pleev xim ua cov roj nplaum, uas yog siv los kos cov xov hlau uas tsis tas yuav muaj qhov pom kev siab, thiab cov duab nrawm yog tsawg. Kev kos duab roj siv cov roj tshwj xeeb los ua cov roj nplua nyeem, uas yog siv rau kev kos duab ci ntsa iab nrog cov kev xav tau zoo ntawm qhov chaw. Nws yog tus cwj pwm los ntawm kev ua kom lubricity zoo thiab ua kom txias thiab ua kom nrawm nrawm.
2. Raws li kev kos duab nrawm ntawm cov khoom siv, nws tuaj yeem muab faib ua qhov nruab nrab thiab qis-ceev daim duab thiab high-speed drawing. Nrog rau kev txhim kho ntawm cov txheej txheem thev naus laus zis, tus nqi nruab nrab thiab qis-ceev daim duab kuj nce ntxiv.
3. Raws li cov khoom siv kos duab, muaj cov hlau tsis muaj carbon steel, nruab nrab carbon steel, siab carbon steel, stainless hlau, tooj liab, txhuas, thiab lwm yam ntaub ntawv.
4. Raws li seem ntawm lub workpiece, nws tuaj yeem muab faib ua cov khoom seem workpiece kos duab thiab hollow seem kos duab. Cov khoom seem dawb paug yog kos rau hauv ntau yam tshwj xeeb thiab cov duab ntawm cov hlau, ntawm cov txheej txheem ntawm kev kos duab puag ncig cov hlau yog qhov yooj yim tshaj plaws. Cov kav dej ntawm ntau yam duab yog kos los ntawm hollow seem blanks. Thaum cov yeeb nkab phab ntsa feem ntau stretched, cov tub ntxhais pas nrig thiab caj npab dawb paug dhau los ntawm cov pwm kom ua tiav txoj kab uas hla thiab txo phab ntsa.
3. Qhov teeb meem ntawm kev kos duab
1. Cov teeb meem tshwm sim ntawm qhov loj thiab nruab nrab txoj kab uas hla hlau rods yog: ①Cov hlau pas nrig tsis ci thiab muaj cov cim rub; ② Cov kab mob hnyav heev thiab cov pwm hnav hnyav heev; xeb;
2. Cov teeb meem tshwm sim ntawm me me txoj kab uas hla hlau rods yog: ① Kev tawg ntawm cov hlau tsis tu ncua thiab shrinkage loj; ② Cov hlua hlau tsis ci thiab muaj khawb; ③ Cov hlua hlau yog oxidized thiab tsis muaj xim;
3. Cov teeb meem tshwm sim ntawm micro-diameter xov hlau yog: ① Kev tawg ntawm cov hlau tsis tu ncua thiab cov xaim loj heev; ② Lub workpiece yog adsorbed tiag tiag thiab nyuaj los ntxuav;
Plaub, kev xaiv ntawm kev kos duab roj
1. Raws li cov khoom sib txawv hauv cov hlau kos duab, cov qauv ntawm cov roj teeb uas tsim nyog yuav txawv. Piv txwv li, kev kos duab ntawm cov hlau tsis muaj hlau yuav tsum tau siv cov roj pleev tshwj xeeb rau cov hlau tsis muaj steel. Yog li ntawd, thaum yuav khoom, koj yuav tsum xaiv hom roj uas tsim nyog raws li cov khoom siv tiag tiag;
2. Cov txheej txheem kev kos duab sib txawv muaj qhov kev ua tau zoo sib txawv rau kev kos duab roj, yog li nws yuav tsum xaiv cov roj kos duab nrog kev ua haujlwm zoo raws li cov txheej txheem tiag tiag (xws li kos duab nrawm, txo qhov sib piv, qhov ua tiav ntawm qhov chaw ua haujlwm, thiab lwm yam);
3. Cov formulations ntawm ntau hom kev kos duab roj tsis zoo ib yam, thiab kev ua haujlwm ntawm cov txheej txheem tiag tiag txawv, yog li cov khoom siv kuj sib txawv.
