Qhov nrov tshaj plaws shearing tshuab lag luam, xuas nrig ntaus, yog siv los txhuam sheared slug. Shearing kuj tshwm sim ntawm qhov punch thiab tuag. Punching, Txiav, blanking, Piercing, notching, Perforating, thiab nibbling yog tag nrho ntawm cov haujlwm shearing.
1. Punching lossis Blanking:
Siv cov xuas nrig ntaus kom tshem tawm cov khoom siv los ntawm cov ntawv hlau los yog ib qho tseem ceeb tshaj plaws yog hu ua blanking lossis xuas nrig ntaus. Punching txhais tau tias tshem cov khoom me me; blanking txhais tau tias tshem tawm cov seem me me thiab qhov seem uas yuav pab tau.
2. Txiav:
Tsawg heev cov hlau yog kis tau rau ntawm lub dav hlau parting thaum poob forging los yog tuag-casting qhov chaw ntau lawm. Cov hlau ntxiv, hu ua flash, raug tshem tawm ntawm ib feem thaum lub sij hawm trimming txheej txheem ua ntej nws yuav siv. Blanking thiab trimming yog cov txheej txheem zoo sib xws, thiab cov tuag siv hauv txhua qhov txheej txheem zoo sib xws.
3. Kev tho
Piercing yog lub ntsiab lus ntawm tearing ib lub qhov nyob rau hauv hlau. Vim tias slug tsis tsim thaum lub sijhawm tho, nws txawv ntawm kev xuas nrig ntaus. Ib lub qhov drilled zoo ib yam li lub qhov mos txwv nyob rau hauv ib daim ntawv hlau zoo sib xws.
4. Neeb
Nibbling yog ib qho tshwj xeeb notching qhov twg cov hlau yog hlais nrog overlapping notches. Nibbling yog siv los tsim cov duab uas xav tau, xws li flanges lossis dab tshos.
5. Perforating
Cov txheej txheem ntawm kev tsim kom muaj qhov sib txawv ntawm qhov nyob rau hauv ib daim ntawv hlau uas tuaj yeem ua txhua qhov loj lossis cov duab thiab npog tag nrho cov ntawv yog hu ua qhov no.
