Qee qhov hloov mus cuag tau yog ua los ntawm tin tooj liab cov khoom, uas yuav tsum muaj qhov zoo elasticity, hnav tsis kam, diamagnetism thiab corrosion kuj. Vim tias qhov zoo ntawm cov seem, hauv cov txheej txheem stamping thiab khoov, thiaj li ua rau cov ntu tiav muaj qhov nro thaum nws tswj hwm qee qhov muaj zog thiab elasticity, thiab kom tsis txhob tawg ntawm lub ces kaum thaum lub workpiece yog khoov, hom no ntawm cov khoom siv workpiece raug rau qhov tsim nyog annealing kev kho mob. Vim li no, yuav ua li cas thiaj tsim cov txheej txheem ua cov txheej txheem tsim nyog thiab cov txheej txheem kho cua sov kom ua tau raws cov qauv tsim thiab cov khoom lag luam tsim ntawm ntu yog qhov tsim nyog heev.
1. Hu rau cov khoom siv thiab cov khoom siv ua kom sov
(1) Cov khoom siv 2.5mm tuab cov tin bronze ntawv.
(2) Yuav tsum kho cov cua sov Tom qab sib tw, cov haujlwm ua kom muaj qhov tawv txaus thaum tswj qee lub zog thiab elasticity, yog li yuav tsum tsis txhob muaj cov kab nrib pleb los yog ua teeb meem vim kev ua haujlwm nyuaj thaum stamping thiab khoov.
2. Cov neeg tiv toj yog muaj teeb meem ntau hauv cov txheej txheem thaiv pob thiab khoov
Thaum cov tin bronze daim ntawv ua tiav ncaj nraim yam tsis sib xws kev kho cua sov, qee yam ntawm kev ua haujlwm lub zog ua haujlwm tshwm sim vim yog cov khoom sib cuag tom qab xuas nrig ntaus (suav nrog xuas nrig ntaus, txiav grooves, thiab lwm yam) mus rau hauv cov thawj tswj kev ua haujlwm, ua rau tom qab tom qab lub sijhawm ua haujlwm. , qhov tsis zoo ntawm kev tawg thiab punch qhov hnav ntawm qhov tuag yog qhov muaj tshwm sim; tib lub sijhawm, vim yog qhov tsis txaus tawv, cov khoom tawg yooj yim tawg, tsis yooj yim rau kev tsim, thiab muaj kev cuam tshuam rau qhov kawg ntawm qhov loj me ntawm qhov seem thaum txheej txheem khoov. Vim li no, nws yog qhov tsim nyog los tsim cov kab ua kom tsim nyog thiab cov txheej txheem kev kho cua sov kom ua tau raws li cov qauv tsim thiab cov khoom lag luam ntawm cov ntu.
3. Teem cov ntu ua khoom
Raws li cov duab ntawm cov feem, cov yam ntxwv ntawm cov khoom siv ua khoom siv thiab cov txheej txheem ntawm kev siv, thiab kev hloov pauv ntawm cov khoom ntiag tug ntawm cov feem thaum ua, qhov kev coj ua tuaj yeem tau ntxig raws li: rab riam thiab txiab amping stamping → annealing → khoov → annealing → dabtsi yog khoov → nto kev ua thiab lwm cov txheej txheem ua.
