Ma laser amakono amatha kudula chitsulo, chitsulo chosapanga dzimbiri, ndi aluminiyamu ndi luso lapamwamba komanso lolondola.
Pakadali pano, kudula kwa waterjet kumagwiritsa ntchito madzi amphamvu kwambiri—nthawi zambiri osakanikirana ndi chotsukira—kudula zinthu. Ubwino wa kudula kwa waterjet ndikuti sikupanga malo okhudzidwa ndi kutentha, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito zinthu zomwe zimakhudzidwa ndi kusintha kwa kapangidwe ka kutentha, kapena ntchito zomwe zimafuna mtundu wokhazikika wa zinthu.
5. Kuchiza Kutentha Kwamakono: Kulamulira Katundu wa Makina Molondola
Zipangizo za makina sizimangopangidwa ngati "zofanana"; zitsulo zimafunikanso kukonzedwa kuti zikwaniritse kuuma, kulimba, komanso kukana kuvala komwe kumafunikira pantchito yawo. Mankhwala amakono otenthetsera monga kuuma kwa vacuum, kuuma kwa induction, ndi carburizing yolamulidwa amawongolera kwambiri khalidwe la chitsulo.
Ukadaulo wamakono wothira kutentha kwa ng'anjo umagwiritsa ntchito njira yowongolera kutentha kwa digito, mlengalenga wolamulidwa, ndi masensa olondola kuti atsimikizire kuti njira zotenthetsera ndi kuziziritsa zikugwirizana ndi zofunikira. Izi zimapangitsa kuti pakhale zotsatira zofanana, chiopsezo chocheperako cha zolakwika, komanso magwiridwe antchito abwino—monga magiya, ma shaft, ndi ma bearing housings omwe amagwira ntchito pansi pa katundu wambiri.
6. Uinjiniya Wapamwamba: Kuphimba ndi Kuteteza Bwino
Kuti zipangizo za injini zisawonongeke ndi dzimbiri, kukangana, ndi kutentha kwambiri, ukadaulo waukadaulo wa pamwamba umagwiritsidwa ntchito. Njira zina zodziwika bwino kwambiri ndi izi:
– PVD (Kutulutsa nthunzi m'thupi) ya zokutira zopyapyala komanso zolimba pa zida ndi zigawo zake zolondola.
– Zophimba zolimba zolowa m'malo mwa chrome zomwe siziwononga chilengedwe, monga kupopera HVOF (High Velocity Oxygen Fuel).
- Kupaka mafuta odzola a aluminiyamu kuti awonjezere kukana dzimbiri ndikulimbitsa pamwamba.
- Kuyika nitriding kuti kuwonjezere kuuma kwa pamwamba pa chitsulo popanda kupangitsa kuti chitsulocho chisinthe kwambiri.
Ndi uinjiniya wa pamwamba, moyo wa zinthu umawonjezeka, nthawi yosamalira makina imatha kukulitsidwa, ndipo chiopsezo cha kulephera chifukwa cha kuwonongeka kapena dzimbiri chingachepe.
7. Makina Odzichitira Zinthu Zokha, Ma Robotic, ndi Mafakitale Anzeru
Mafakitale amakono amadalira kwambiri maloboti a mafakitale kuti aziwotcherera, kusamalira zinthu, kupukuta, ndi kuyang'anira. Maloboti amatha kugwira ntchito mokhazikika komanso mobwerezabwereza pa liwiro lalikulu, zomwe zimachepetsa chiopsezo cha ngozi kuntchito pazinthu zoopsa monga kuwotcherera kwambiri kapena kunyamula zinthu zolemera.
Fakitale yanzeru kapena lingaliro la Industry 4.0 limaphatikiza makina opanga ndi makina odziwitsa kudzera pa intaneti ya Zinthu (IoT). Masensa amayikidwa pamakina kuti aziwunika kugwedezeka, kutentha, kuchuluka kwa injini, ndi zina. Deta iyi imasanthulidwa kuti:
- Kukonza zinthu moganizira zomwe zingachitike, kuti makina asawonongeke mwadzidzidzi.
