Momwe mungathetsere slag yomatira pamene laser kudula aluminiyamu mbale

Kudula kwa aluminiyamu pogwiritsa ntchito laser (komwe kumadziwikanso kuti kulendewera kwa slag, slag) ndi vuto lofala, makamaka chifukwa cha kutentha kwambiri kwa aluminiyamu, malo otsika osungunuka, kusungunuka mosavuta komanso kukhuthala kwa sungunuka ndi zina. Kuti vutoli lithe bwino, ndikofunikira kukonza bwino mpweya, magawo, zipangizo, zida ndi njira 5. Zotsatirazi zimapereka mayankho okwanira:

Kiyi yayikulu: kusankha ndi kukonza mpweya wothandiza (iyi ndiye gawo lofunika kwambiri)

1. Nayitrogeni yoyera kwambiri ndi yabwino kwambiri

• Mfundo: Nayitrogeni ngati mpweya wopanda mpweya imatha kuletsa kusungunuka kwa aluminiyamu ndikuchepetsa kupangika kwa zotsalira zomata za aluminiyamu (Al₂O₃). Nthawi yomweyo, nayitrogeni wopanikizika kwambiri amatha kupukutira madzi osungunuka a aluminiyamu pansi kuchokera pamng'alu, m'malo momangirira mbali ndi mbali.
• Kufunika kwa ukhondo: ≥ 99.99% (99.995% kapena kupitirira apo akulimbikitsidwa). Kusayera ndi chimodzi mwa zifukwa zazikulu zomwe zimamatira matope.
• Zofunikira pa kuthamanga kwa mpweya: malinga ndi kusintha kwa makulidwe a mbale, nthawi zambiri zimakhala zapamwamba (monga kudula mbale ya aluminiyamu ya 3mm kufika pa 1.5-2.0MPa). Kuthamanga kosakwanira sikuchotsa bwino kusungunuka.

2. Mpweya wopanikizika wapamwamba kwambiri (njira ina yotsika mtengo)

• Zochitika zomwe zingagwiritsidwe ntchito: zofunikira zapamwamba pamtundu wotsika sizili zapamwamba, kapena mbale yopyapyala ya aluminiyamu (monga ≤ 3mm) yopangira makina okhwima.
• Zofunikira:
• Ayenera kukhala ndi makina owumitsira oziziritsa bwino komanso zosefera zolondola kuti mpweya usakhale ndi madzi komanso mafuta. Chinyezi ndi mafuta zidzawonjezera kukhuthala kwa aluminiyamu ndikumatira kwa slag.
• Kupanikizika kuyenera kukhala kokhazikika mokwanira.

3. Mpweya (ntchito yapadera)

• Mfundo: Gwiritsani ntchito njira yothira okosijeni kuti mupereke kutentha kowonjezera ndikuwonjezera liwiro lodulira. Komabe, kuchuluka kwa alumina slag yolimba komanso yolimba kudzapangidwa mosalephera, zomwe nthawi zambiri sizimalimbikitsidwa podulira zomwe sizikufuna kuti slag imamatire, koma pokhapokha pazochitika zomwe zimafuna kufunikira kochepa kwambiri pamwamba kapena kukonza pambuyo pake.

kudula magawo okonza

Ma parameter ayenera kufananizidwa ndi gasi kuti athetse vuto la dongosolo.

1. Mphamvu ndi liwiro loyenera:

• Mphamvu yake ndi yokwera kwambiri/liwiro lake ndi lochedwa kwambiri: mphamvu yochulukirapo imayambitsa kusungunuka kwa aluminiyamu mopitirira muyeso, dziwe losungunuka limakula, mpweya umavuta kuupukutira, ndipo pansi pake pamakhala matope ozungulira.
• Mphamvu ndi yochepa kwambiri/yachangu kwambiri: mphamvu yosakwanira, zinthu sizidulidwa kapena pansi pazizira mofulumira kwambiri, kusungunuka kudzauma m'mphepete mwake kusanatuluke.
• Njira yochotsera zolakwika: kutengera magawo omwe akulimbikitsidwa, mayeso a liwiro la makwerero amachitika kuti apeze "malo abwino" omwe amangodula ndikupachika slag yochepa kwambiri ".

2. Kuchuluka kwa nthawi ndi ntchito:

• Kuchepetsa ma frequency ndi kusintha kayendedwe ka ntchito nthawi zina kumathandiza kuwongolera kutentha komwe kumalowa ndikuchepetsa kutentha kwambiri pansi. Pa ma plates owonda, ma frequency apamwamba angagwiritsidwe ntchito.

3. Malo ofunikira:

• Yesetsani kuchepetsa pang'ono kulunjika (negative defocus) kuti mphamvu ikhale yolimba kwambiri mu theka la pansi la mbale, zomwe zimathandiza kutulutsa kusungunuka kuchokera pansi. Iyi ndi njira yothandiza yowongolera slag yopachikika pansi. Iyenera kukonzedwa bwino malinga ndi momwe zinthu zilili.

Mkhalidwe wa Zida ndi Zogwiritsidwa Ntchito

1. Kuyang'anira ndi kusankha nozzle:

• Momwe zilili: Onetsetsani kuti nozzle yatha, siiwonongeka, ndipo siikuwonongeka pakati. Nozzle yotha ntchito imapangitsa kuti mpweya ukhale wosasunthika ndipo mpweya wotuluka m'madzi ukhale wofooka.
• M'mimba mwake: nthawi zambiri amagwiritsa ntchito nozzle yayikulu (monga φ2.0mm kapena kupitirira apo) yokhala ndi nayitrogeni wopanikizika kwambiri, yomwe ingapangitse kuti chotchinga cha mpweya chikhale cholimba komanso chachikulu chikhale chotchinga.

2. Ubwino wa mtanda:

• Onetsetsani kuti lenzi ya mutu wa laser (galasi loyang'ana, galasi loteteza) ndi yoyera komanso yopanda kuipitsa, ndipo onetsetsani kuti mphamvu ya kuwala kwa dzuwa ndi yofanana komanso yokhazikika.

Kukonzekera zinthu ndi njira

1. Pamwamba ndi zinthu za mbale ya aluminiyamu:

• Kuyeretsa: Chotsani mafuta, fumbi ndi oxide pamwamba pa mbale ya aluminiyamu musanadule. Chotsukira chapadera cha aluminiyamu chingagwiritsidwe ntchito.
• Gulu la aloyi: magwiridwe antchito osiyanasiyana a aluminiyamu ndi osiyana. Kawirikawiri magulu 5 (monga 5052) kuposa magulu 6 (monga 6061) ndi odula bwino, slag yochepa. Silicon, magnesium ndi zinthu zina zomwe zimakhala ndi kukhuthala kwakukulu kwa aloyi zimakhala zazikulu.
• Okisidi wosanjikiza: ngati pali khungu lokhuthala la okosidi pamwamba pa mbaleyo, likhoza kupukutidwa pang'ono kapena kuviikidwa mu viniga.

2. Mtunda wogwirira ntchito:

• Onetsetsani kuti mtunda wochokera ku nozzle kupita ku mbale ndi wofanana komanso woyenera (nthawi zambiri 0.5-1.5mm). Kukwera kwambiri kudzachepetsa kuthamanga kwa mpweya.

3. Kuboola ndi kuboola chitsulo:

• Konzani bwino magawo obowola kuti madzi asatulukire pamwamba panthawi yobowola.
• Gwiritsani ntchito zingwe zakunja kapena zingwe za arc kuti mupewe kusonkhanitsa zinyalala kumayambiriro kwa mawonekedwe a workpiece.

Chithandizo pambuyo podula (njira yochiritsira)

Ngati pali slag pang'ono yopachika, njira zotsatirazi zitha kuchitidwa:

1. Kuchotsa thupi:Gwiritsani ntchito chokokera, burashi yachitsulo chosapanga dzimbiri kapena chotsukira kuti muchotse pamanja. Pa slag yolimba ya mbale yolemera, chopukusira chaching'ono chokhala ndi gudumu lapadera la nayiloni chingafunike.

2. kuyeretsa mankhwala:Kugwiritsa ntchito madzi apadera oyeretsera aluminiyamu kapena madzi oyeretsera a alkaline ochepetsedwa, kungathe kusungunula gawo la slag yomata. Kumbukirani kupewa kugwiritsa ntchito ma acid amphamvu ndi alkali, ndipo mutalandira chithandizo muyenera kutsukidwa bwino ndi madzi ndikuwumitsa.

3. Kuphulitsa mchenga:Pazigawo za batch kapena zomwe zimafuna malo ofanana osawoneka bwino, mchenga wosalala (monga mikanda yagalasi) ungagwiritsidwe ntchito popaka mchenga.

Kudzera mu kafukufuku ndi kukonza bwino komwe kwatchulidwa pamwambapa, vuto la kukana kwa slag pa mbale ya aluminiyamu yodula ndi laser lingathe kulamulidwa bwino kuti lidulidwe bwino. Chofunika kwambiri ndikumvetsetsa kuti "kuchotsa mpweya woyera bwino" ndiye maziko, ndipo magawo ena onse amagwirizanitsidwa mozungulira maziko awa.
