N'zosapeweka kuti mavuto amachitika pogwiritsa ntchito makina odulira laser, ndiye mungathetse bwanji mavutowa? Yang'anani mafunso 7 otsatirawa. Kodi mwakumana nawo mukugwira ntchito?
1. Njira yodulira nkhonya. Njira iliyonse yodulira kutentha, kupatulapo nthawi zina pomwe imayambira m'mphepete mwa bolodi, nthawi zambiri imafuna dzenje laling'ono m'bolodi. Makina odulira ndi laser asanagwiritse ntchito nkhonya, choyamba timachotsa dzenje, kenako timagwiritsa ntchito laser kuchokera ku kafukufuku wofufuza za chitukuko cha dzenje laling'ono. Pali njira ziwiri zazikulu zolowera mu laser cutter popanda kugwiritsa ntchito chobowola:
Kuboola kwa pulasitiki - Zipangizozo zimayatsidwa ndi laser yopitilira kuti zipange crater pakati pa chinthucho, chomwe chimasakanikirana mwachangu ndikuchotsedwa ndi mtsinje wa okosijeni wa okosijeni ndi kuwala kwa laser. Kawirikawiri, kukula kwa dzenjelo kumagwirizana ndi makulidwe a mbale. M'mimba mwake wapakati wa dzenje loboola ndi theka la makulidwe a mbaleyo. Chifukwa chake, m'mimba mwake wa dzenje loboola la mbale yokhuthala ndi yayikulu osati yozungulira, yomwe si yoyenera magawo omwe ali ndi zofunikira kwambiri pakukonza. Ingochotsani. Kuphatikiza apo, chifukwa kupanikizika kwa mpweya komwe kumagwiritsidwa ntchito ndi bizinesiyo ndi kofanana ndi komwe kumadulidwa, kupopera kumakhala ndi mphamvu yayikulu.
Pulse Punch - Imagwiritsa ntchito laser yothamanga kwambiri kuti isungunuke kapena kuwononga zinthu zochepa. Mpweya kapena nayitrogeni nthawi zambiri imagwiritsidwa ntchito ngati mpweya wothandizira kuchepetsa kufutukuka kwa mabowo komwe kumachitika chifukwa cha kusungunuka kwa exothermic. Kupanikizika kwa mpweya kumakhala kochepa kuposa kupsinjika kwa okosijeni panthawi yodula. Kugunda kulikonse komwe kumachitika ndi laser kumapanga ndege yaying'ono ya tinthu tating'onoting'ono tomwe timapangidwa pang'onopang'ono, kotero timafunikira nthawi yodumphira mbale yokhuthala m'masekondi ochepa. Kudumphadumpha kukatha, dulani ndi mpweya m'malo mwa mpweya wothandizira. M'mimba mwake wodumphadumpha woterewu umakhala ndi mphamvu yochepa ndipo ubwino wake wodumphadumpha ndi wapamwamba kuposa kuphulikadumpha. Laser yomwe imagwiritsidwa ntchito podumphadumpha ndi laser siyenera kukhala ndi mphamvu yotulutsa mphamvu zambiri, komanso kukhala ndi mawonekedwe a nthawi ndi malo a mtanda, kotero laser ya CO2 yodutsa mtunda wonse sangakwaniritse zofunikira zodumphadumpha ndi laser. Kuphatikiza apo, ndikofunikira kukhala ndi njira yodalirika yowongolera njira ya gasi kuti muzindikire mitundu yosiyanasiyana ya gasi, kusintha kwa kupanikizika kwa gasi ndi nthawi yobowola.
Kuti mupeze kudula kwapamwamba kwambiri, chisamaliro chiyenera kuperekedwa ku ukadaulo wosinthira kuchokera pakubowola kwa pulse pamene workpiece ili pampando kupita ku kudula kosalekeza kwa liwiro lokhazikika. Polankhula za chiphunzitso, nthawi zambiri zimatha kusintha mikhalidwe yaukadaulo yodulira ya gawo lofulumira la bizinesi, monga kutalika kwa focal, malo a nozzle, kuthamanga kwa mpweya, ndi zina zotero, koma kwenikweni, sizingatheke kusintha zinthu zoposa chimodzi mwa izi chifukwa nthawi yogwira ntchito ndi yochepa kwambiri. Pakupanga mafakitale, ndizotheka kusintha mphamvu yapakati ya laser posintha m'lifupi mwa pulse, pulse frequency, pulse m'lifupi ndi pulse frequency. Kusanthula zotsatira zenizeni za kafukufuku kukuwonetsa kuti njira yachitatu ili ndi zotsatira zabwino kwambiri.
2. Kusanthula kusintha kwa njira yodulira makiyi. Izi zili choncho chifukwa zida zamakina zaku China (zokhazo za makina odulira laser amphamvu kwambiri) sizingatenge kubowola kwa blasting pokonza makiyi, koma zimagwiritsa ntchito kubowola kwa pulse (kubowola kofewa), zomwe zimapangitsa kuti chitukuko cha mphamvu ya laser m'dera laling'ono la ana chikhale chodzaza kwambiri, ndipo malo osagwiritsidwa ntchito pokonza makiyi amawotchedwa. Zimayambitsa kusintha kwa mabowo, zomwe zimakhudza mtundu wa zinthu zomwe zimapangidwa komanso zomwe zimagwiritsidwa ntchito pokonza. Pakadali pano, mu njira yopangira makiyi, njira yobowola ya pulse (kubowola kofewa) iyenera kusinthidwa kukhala njira yobowola ya blasting (kubowola wamba) kuti athetse vutoli. Ndipo pa makina odulira ang'onoang'ono a laser amphamvu ndi zosiyana, njira yopangira mabowo m'bowo iyenera kutenga njira zosiyanasiyana zobowola pulse kuti apange mawonekedwe abwino pamwamba.
Kuthetsa vuto la burr yachitsulo chotsika mpweya pogwiritsa ntchito laser, malinga ndi mfundo yoyambira ya CO2 laser cutting ndi kapangidwe ka maphunziro, kusanthula kungatheke kuti pali zifukwa zotsatirazi: chifukwa chachikulu chomwe chimayambitsa vuto lalikulu ndi ntchito yopangira burr ndi: laser focus mmwamba ndi pansi si yolondola, chifukwa chake ndikofunikira kuchita mayeso a focus, malinga ndi momwe anthu amaganizira za kusintha kwa offset; mphamvu yotulutsa ya laser si yokwanira, tiyenera kuwona ngati antchito a jenereta ya laser akhoza kukhala abwinobwino, ngati si abwinobwino, kenako tiwone ngati njira yotulutsira ya batani lolamulira laukadaulo wa laser iyenera kukhala yolondola, kuti isinthidwe; Liwiro lodulira ndi lochedwa kwambiri, kotero ndikofunikira kuwonjezera liwiro la linear mu opareshoni yeniyeni. Kuyera kwa kudula mpweya sikokwanira, chifukwa chake ndikofunikira kupanga kuti pakhale kasamalidwe kodulira kabwino kwambiri komwe kumagwirira ntchito, chifukwa cha mpweya; laser focus offset, chifukwa cha kuyesa malo olunjika, chifukwa cha kasamalidwe ka offset nthawi zonse kumasinthidwa; chida chamakina chikagwira ntchito kwa nthawi yayitali, mphunzitsi ayenera kuzimitsa ndikuyambiranso.
Kusanthula kwa burr kwa chitsulo chosapanga dzimbiri ndi aluminiyamu zinc plate workpiece burr, kuonekera kwa zochitika izi, choyamba ndikofunikira kuganizira kudula chitsulo chotsika mpweya pamene burr ikupanga zinthu, koma n'kosapeweka kungofulumizitsa liwiro lodula, chifukwa nthawi zina kudula mbale sikumavala vutoli, izi ndizofunikira kwambiri pokonza mbale ya zinc ya aluminiyamu. Pakadali pano, tiyenera kuganizira ngati nozzle iyenera kusinthidwa, kayendetsedwe kosakhazikika ka njanji yowongolera ndi zina zomwe ziyenera kuthetsedwa.
5 laser si kudula kwathunthu momwe kusanthula kumachitikira, kusanthula kungapezeke kudzera m'mikhalidwe yosiyanasiyana iyi ndi chitukuko chachikulu cha kusakhazikika komwe kumakhudza khalidwe la kukonza: kusankha kwa nozzle ya mutu wa laser ndi makulidwe a mbale yopangira sikukugwirizana; Liwiro la mzere wodula wa laser ndi lachangu kwambiri, tifunika luso lathu lowongolera makina ogwiritsira ntchito kuti tichepetse liwiro la mzere; Kulowetsa nozzle sikuloledwa kutsogolera ku malo owunikira a laser. Cholakwika ndi chachikulu kwambiri, tifunika kuyambiranso kuti tidziwe deta yolowetsa nozzle, makamaka pamene kudula aluminiyamu ndiko komwe kungayambitse.
Kudula chitsulo chotsika 6 chopanda mpweya wabwino kwambiri. Kukonza zinthu molakwika kumeneku kudzakhudza mbali za kapangidwe kake komaliza. Ngati magawo ena ndi abwinobwino, zinthu zotsatirazi ziyenera kuganiziridwa: NOZZEL ya mutu wa laser yatayika. Bwezerani nozzle pakapita nthawi. Ngati palibe nozzle yatsopano yosinthira chikwamacho, malo ogwirira ntchito ayenera kuwonjezeredwa ndi mpweya kudzera mu kupanikizika; Ulusi pakati pa nozzle ndi mutu wa laser ndi womasuka. Pakadali pano, tiyenera kuyimitsa kudula nthawi yomweyo, kuyang'ana momwe kulumikizana kwa mutu wa laser kulili, ndikubwezeretsanso ulusi.
7. Tetezani lenzi kuti ipange utsi wa madzi mu njira yodulira makina odulira laser, mpweya wothandiza ndi wofunikira! Pakati pawo, mpweya ndi nayitrogeni zimagwiritsidwa ntchito kwambiri m'dziko lathu. Zachidziwikire, kuyera kwa mpweya kumakhala kwakukulu, komanso mtundu wa kudula udzakhala wabwino kwambiri. Pali makasitomala ambiri omwe akufuna kusunga ndalama zodulira mpweya, koma nthawi zonse pamakhala chifunga chomwe chimateteza lenziyo mu njira yodulira, ubwino wodula ndi wochepa kwambiri, chifukwa chiyani?
Choyamba, tipatseni kutchuka konse, udindo wa mpweya wothandiza: 1. Kutulutsa zotsalira, kuti tipeze njira yabwino kwambiri yodulira. 2. Gwiritsani ntchito mpweya kuti mutulutse chitsulo chosungunuka.
