Buku Lotsogolera Lonse Lokhudza Kuchotsa Ma Laser-Cutting Burrs ndi Slag Adherents! Mafakitale 90% agwera mu misampha iyi.

Ogwiritsa ntchito laser nthawi zambiri amavutika ndi ma burrs ndi slag adhesion. Pambuyo podula, workpiece imakhala ndi m'mphepete mopingasa komanso slag adhesion pansi, zomwe sizimangofunika kupukutidwa ndi kusinthidwa, kuchepetsa kupanga, komanso zimapangitsa kuti zinthu ziwonongeke, kulondola kwa zinthu zosagwirizana, komanso ngakhale kukonzanso kapena kutaya dongosolo.

Anthu ambiri, akakumana ndi vuto, amasinthasintha mphamvu kapena liwiro lake mosazindikira, pothana ndi zizindikiro zokha popanda kuthana ndi chomwe chimayambitsa vutoli. Ndipotu, zifukwa zazikulu zomwe zimayambitsa ma burrs ndi slag adhesion mu laser cutting zimagawidwa m'magulu anayi akuluakulu:magawo a njira zosafanana, kupotoka kwa njira yowunikira, zolakwika mu dongosolo la pneumatic, ndi kuwonongeka kwa zida.Lero, ndikugawana nanu buku lothandiza kwambiri lothandizira kuthetsa mavuto ndi njira zothetsera mavuto zomwe ngakhale oyamba kumene angathe kuzidziwa bwino.

Choyamba, fotokozani momveka bwino: ma burrs ndi slag si chinthu chimodzi.

Akatswiri ambiri amakonda kusokoneza zinthu ziwirizi, zomwe zimapangitsa kuti pakhale njira zolakwika zochotsera zolakwika. Mavuto angathetsedwe bwino pokhapokha ngati adziwa chomwe chimayambitsa vutoli.

Burr:Chodulidwa m'mphepete mwake chocheperako, chopindika kwambiri, chopindika, chodulidwa pang'onopang'ono, chomwe chikufunika kufulumizitsidwa, chitsulo chosungunuka sichinachotsedwe kwathunthu, kuzizira ndi kulimba, chofala mu chitsulo chosapanga dzimbiri, kudula mbale yopyapyala.

Kupachika zinyalala:Kudula kwambiri kwa slag komwe kumakhala kolimba komanso kolimba pansi pa workpiece sikophweka kugwa, makamaka chifukwa cha mpweya wochepa wowonjezera komanso kuchuluka kwa slag komwe sikungathe kuphulika, zomwe zimapangitsa kuti kudula kwa mbale zokhuthala komanso kudula mabowo ang'onoang'ono kukhale kwakukulu.

Czifukwa za miyala + mayankho olondola (zinthu zouma zogwira ntchito)

1. Kuchepetsa Kuyang'ana Kwambiri: vuto lalikulu lomwe silingalandiridwe mosavuta

Malo owunikira pogwiritsa ntchito laser amatsimikiza mwachindunji kuchuluka kwa mphamvu yodulira, kuyang'ana kwambiri, kutsika kumabweretsa msoko wodula wosazolowereka, zotsalira za slag. Kupotoka kwa plate yopyapyala kudzawoneka ngati m'mphepete mwa burr, kuyang'ana kwambiri kwa plate sikuloledwa kupachika malo ambiri a slag.

Yankho: Chitsulo cha carbon steel chopyapyala chikhoza kuyikidwa pa 0.5mm pamwamba kapena pansi pang'ono pa mbale kuti chiwonjezere mphamvu yodulira pansi; Burr yakutsogolo imawonekera podula, makamaka chitsulocho chimakhala chotsika kwambiri, chomwe chingasinthidwe moyenera. Chitsulo choyipa chiyenera kukonzedwa bwino kuti chidulidwe cha mbale chokhuthala chikhale ndi mphamvu zokwanira mu ndondomeko yonse ya mbaleyo komanso kudula kowonekera. Ndikofunikira kuti muwongolere chitsulocho kamodzi patsiku.

2. Kusalingana kwa magawo: mphamvu ndi liwiro sizikugwirizana

Ngati liwiro lodulira ndi lachangu kwambiri, laser sidzasungunuka mokwanira ndikulowa mu mbale, zomwe zimapangitsa kuti pakhale ma burrs abwino. Ngati liwiro lichepa kwambiri, mbaleyo idzasungunuka kwambiri, ndipo dziwe losungunuka lidzakula ndikusonkhanitsa slag yolemera. Ngati mphamvu ili yotsika kwambiri, kudula sikudzadutsa ndikusiya zotsalira. Ngati mphamvu ili yokwera kwambiri, pamwamba pa kudulapo padzaphwanyika ndi kugwedezeka.

Yankho: Tsatirani mfundo ya "kudula mwachangu mbale zoonda ndi kudula pang'onopang'ono mbale zokhuthala. Kuphulika pang'ono kwa mbale yoonda kumatha kuwonjezera mphamvu ndikuchepetsa liwiro pang'ono. Ngati mbale yokhuthala ili ndi slag yoopsa, liwiro lidzakonzedwa bwino poyamba kuti lisasungunuke kwambiri, ndipo nthawi yomweyo phatikizani ndi ma frequency oyenera a laser kuti muwonetsetse kuti kudula kuli kokhazikika.

3. Vuto la njira ya gasi: kuthamanga kwa mpweya, kuyera, ndi nozzle ndiye chinsinsi

Ntchito ya mpweya wothandiza ndi kuphulitsa chitsulo chosungunuka ndikuziziritsa pamwamba pake, chomwe ndi chinsinsi chopewera kutayikira kwa slag. Kupanikizika kosakwanira kwa mpweya, kuyera kosakwanira, komanso kutsekeka kwa nozzle ndi kuwonongeka kumayambitsa mwachindunji zotsalira za slag. Kudula kwa okosijeni ndikosavuta kupanga slag ya okosijeni, kuyera kwa nayitrogeni kosakwanira kudzawoneka ngati kukuda kwa gawo, ndipo burr idzawonjezeka.

Yankho: burr pang'ono iwonjezere kuthamanga kwa mpweya moyenera; mbale yokhuthala yolimba yopachika, yofunika kwambiri m'malo mwa kudula kwa nayitrogeni koyera kwambiri. Tsukani zotsalira za nozzle, yang'anani ngati nozzle ndi yolakwika kapena yosiyana, gwirizanitsani nozzle ndi malo otseguka ogwirizana malinga ndi makulidwe a mbale, ndikusunga kutalika kwa nozzle ndi mbale kukhala kofanana komanso kokhazikika.

4. Mavuto a zida ndi mbale: zolakwika zobisika siziyenera kunyalanyazidwa

Kuipitsidwa kwa ma lens, kupotoka kwa njira yowunikira, njanji yowongolera imatsekeka, zingayambitse kuchepa kwa mphamvu ya laser, kusakhazikika kwa beam, zomwe zimapangitsa kuti slag ikulendewera pang'onopang'ono. Kuphatikiza apo, sheet oxide layer ndi yokhuthala kwambiri, kapangidwe ka alloy kosagwirizana, galvanized sheet zinc layer ikusanjikiza, zidzawonjezera kukhuthala kwa slag, zomwe zimakhala zovuta kuzichotsa.

Yankho: Tsukani lenzi yoteteza nthawi zonse, sinthani njira yowunikira ndikuwongolera kulondola kwa njanji. Mukakonza ma plate okhala ndi okosijeni wambiri komanso wokutira wapadera, kwezani mpweya moyenera, konzani bwino malo owunikira, ndikuyeretsani zinyalala pamwamba pa plateyo pasadakhale.

Fnjira yothetsera mavuto a ast (mphindi 3 kuti vuto lithe)

1. Yang'anani mawonekedwe: ma burrs opyapyala amasintha mphamvu ndi liwiro; Zotsalira zolemera zomwe zimapachikidwa kuti ziwone kuthamanga kwa mpweya ndi nozzle

2. Yang'anani zida: yeretsani lenzi, yang'anani nozzle, sinthani malo ofunikira

3. Magawo a nyukiliya: makulidwe ofanana a mbale, liwiro lokonza bwino ndi mphamvu

4. Kuyang'anira mpweya: kutsimikizira kuyera kwa mpweya ndikusintha kuthamanga kwa mpweya ngati pakufunika

Wyodulidwa kumapeto

Kudula kwa laser popanda burr, palibe kupondereza slag, osati mwa kukonza zolakwika mwachisawawa, koma mwa kufananiza magawo ndi kukonza zida tsiku ndi tsiku. Zolakwika zambiri zogwirira ntchito si kulephera kwa zida, koma magawo, njira ya gasi, kuyang'ana kwambiri kupotoka pang'ono. Kuchita bwino pakukonza tsiku ndi tsiku ndi ntchito yokhazikika sikungopulumutsa ndalama zokonzanso ndi kupukuta, komanso kumawonjezera kwambiri kulondola ndi magwiridwe antchito a chinthu chomalizidwa.
