"N'chifukwa chiyani ndingadule chitsulo chosapanga dzimbiri dzulo, koma osagwira ntchito lero? Sindinasinthe chilichonse pa makinawo. Chifukwa chiyani?"
Kodi mukukumana ndi vuto lomweli?
Kusalowa bwino kwa zinthu ndi vuto lodziwika bwino mukudula kwa laser kosapanga dzimbiri, nthawi zambiri zimapangitsa kuti m'mphepete mwake musakhale bwino, kukonza kwachiwiri, komanso kuchepetsa mphamvu yopangira. Ngakhale kuti magawo odulira mu makina owongolera a CNC sangasinthe, kusintha kwa momwe zinthu zilili pakugwira ntchito kumatha kukhudza kwambiri magwiridwe antchito odulira.
Kukambiranaku kukuyang'ana kwambiri mbali zothandiza za uinjiniya, kuphatikizapo momwe nozzle imagwirira ntchito komanso momwe imagwirizanirana, kuthandiza mpweya kupanikizika ndi kuyera, kukhazikika kwa malo olunjika, kuipitsidwa kwa zinthu zowunikira, momwe zinthu zilili pamwamba, komanso kusalala kwa pepala.
Zinthu 5 Zochititsa Chidwi Kwambiri (motsatira njira yodziwira zomwe zingachitike)
1️⃣ Nozzle Yodetsedwa
Zizindikiro: Kudula kodetsedwa pansi pa kerf
Kudula kosakwanira m'malo ena
Nthunzi zikutuluka mmwamba
Mphepete mwachitsulo chodulidwacho chili ndi "kapangidwe ka sawtooth + slag"
Chifukwa chiyani zinali bwino dzulo koma lero sizinali bwino?
Chida cholumikizira ndi gawo logwiritsidwa ntchito:
Yothira ndi slag yosungunuka
Kugundidwa pang'ono ndi chogwirira ntchito
Kuwonongeka kwa chibowo chamkati
Mwina sizingawonekere kwa maso, koma mpweya wasokonekera kale.
Yankho:
Chotsani nozzle ndikuwona ngati dzenjelo ndi lozungulira pogwiritsa ntchito galasi lokulitsira.
Sinthani ndi nozzle yatsopano yoyesera (njira yofulumira kwambiri yotsimikizira).
Chitaninso kuwunikira kwa nozzle concentricity kachiwiri.
Zochitika: M'mafakitale ambiri, 70% ya "mavuto odulira mwadzidzidzi" amachitika chifukwa cha mavuto a nozzle.
2️⃣ Mpweya Wothandiza Wosazolowereka (Kupanikizika/Kuyera)
Chongani: Kodi mphamvu ya nayitrogeni/mpweya ndi yotsika kuposa ya dzulo?
Kodi silinda ya gasi ili pafupi kukhala yopanda kanthu?
Kodi pali kuzizira munjira yoyeretsera?
Kodi valavu ya solenoid imachedwa? Kuzindikira Kosavuta:
Yang'anirani pamene mukudula:
Kodi kupopera kwa nthunzi kumapita pansi (kwabwinobwino)?
Kapena ikubalalika/kufalikira/kukwera mmwamba (vuto la mpweya)?
Yankho:
Yesani kuthamanga kwa mphamvu panthawi yodula
Yesani silinda ina ya gasi
Tulutsani madzi, yang'anani fyuluta
3️⃣ Kuwongolera Malo Oyang'ana
Ngakhale magawo sanasinthe, zitha kukhala chifukwa cha:
Lenzi yoteteza yodetsedwa
Kuwotcha pang'ono kwa lenzi
Kusakhazikika kwa kuyang'ana kokhazikika
Izi zipangitsa kuti:
Pamwamba padulidwa, koma mphamvu sizikwanira pansi → kudula kosakwanira
Yankho:
Tsukani/sinthani lenzi yoteteza
Yambitsaninso cholinga
Yesani kuchepetsa chidwi ndi 0.5 ~ 1mm
4️⃣ Zinthu Zasintha (Zachilendo Kwambiri)
Chithunzi ichi chikuwoneka ngati:
Mulingo wa oxide pamwamba
Kapena makulidwe osagwirizana a mbale
Kapena zinthu zina zapafupi
Mavuto ofala:
Yasinthidwa kukhala gulu lina la mbale
Kuchuluka kosiyana pakati pa m'mphepete ndi pakati pa mbale imodzi
Mafuta, dzimbiri, kapena utoto pamwamba
Yankho:
Yesani makulidwe enieni ndi caliper
Yesani ndi chinthu china
Yesani kudula pa liwiro lochepetsedwa ndi 10-20%.
5️⃣ Z-axis Height Drift / Mbale Yosafanana
Ngati nozzle ili pamwamba kuposa dzulo:
→ Kuchuluka kwa mphamvu kumachepa
→ Kudula kosakwanira pansi
Chongani:
Kodi sensa ya capacitive ndi yodetsedwa?
Kodi kutalika kotsatirako kuli kokhazikika?
Kodi mbaleyo yapindika?
II. Njira Yofulumira Kwambiri Yothetsera Mavuto (Palibe Njira Zosafunikira)
Potsatira ndondomeko iyi, mutha kuzindikira vutoli mu mphindi 10-20:
Sinthani nozzle
Yang'anani ndikusintha lenzi yoteteza
Yesani kuthamanga kwa mpweya
Chepetsani chidwi ndi 0.5–1mm
Yesani kudula pa liwiro lochepetsedwa ndi 15%.
Kawirikawiri, vutoli limathetsedwa ndi sitepe yachiwiri.
Ngati muli ndi mafunso okhudzamakina odulira a laser a fiberKuti mugwiritse ntchito zitsulo, musazengereze kulankhulana nafe.
