5, Lub kaum ntse ntse chamfering blunt.
6, Ntse ntug chamfering blunt, tshem tawm burr ya ntug.
Thib ob, qhov chaw kho qhov chaw
1, qhov chaw ua haujlwm nto, yuav tsum tsis muaj khawb, khawb thiab lwm yam tsis xws luag uas ua rau qhov chaw ntawm qhov chaw puas.
2, Tsis muaj qhov tsis xws luag xws li cov tawv nqaij dub, pob tw, qhov 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. Ua ntej pleev xim, txhua qhov hlau yuav tsum tsis muaj xeb, oxide, roj, plua plav, av nkos, ntsev thiab av.
3, Ua ntej tshem tawm xeb, tshem tawm cov roj thiab cov av ntawm qhov chaw ntawm cov hlau nrog cov organic hnyav, alkali, emulsifier, chav, thiab lwm yam.
4, Lub sij hawm ncua sij hawm ntawm qhov chaw yuav tsum tau coated los ntawm txhaj blasting los yog phau ntawv tshem tawm xeb thiab cov primer txheej yuav tsum tsis txhob ntau tshaj 6h.
5, riveted qhov chaw nyob rau hauv kev sib cuag nrog ib tug nto, ua ntej kev sib txuas yuav tsum tau coated nrog ib tug tuab ntawm 30 ~ 40μm anti-xeb xim. Lub ntug ntawm lub puab tsaig yuav tsum tau kaw nrog cov xim, putty los yog nplaum. Vim yog ua los yog vuam puas rau cov primer, kom repaint.
Thib peb, qhov chaw kho cua sov
1, los ntawm tempering kev kho mob, HRC50 ~ 55.
2, nruab nrab carbon steel: 45 los yog 40Cr qhov chaw rau high-frequency quenching, 350 ~ 370 degree tempering, HRC40 ~ 45.
3, carburizing qhov tob ntawm 0.3mm.
4, kub kub kho kev laus.
Los ntawm qhov sib qhia me me, peb tsis nyob ntawm cov khoom siv tshuab ua cov txheej txheem kev siv tshuab muaj kev nkag siab ua ntej, Kuv vam tias cov ntsiab lus saum toj no yuav pab koj Oh!
