Kodi Pali Njira Yopewera Burr Mukamagwiritsa Ntchito Makina Odulira Laser?
Yankho ndi lakuti inde. Mu ndondomeko ya pepala zitsulo kudula processing, ndi chizindikiro atakhala, mpweya chiyero ndi kuthamanga mpweya wa CHIKWANGWANI laser kudula makina zingakhudze processing khalidwe. Iyenera kukhazikitsidwa molingana ndi zinthu zogwirira ntchito kuti zitheke bwino.
Burrs kwenikweni ndi mochulukira zotsalira particles pamwamba pa zitsulo zipangizo. Pamene azitsulo laser kudula makinaamakonza workpiece, laser mtengo irradiates pamwamba workpiece, ndi kwaiye mphamvu vaporizes pamwamba pa workpiece kukwaniritsa cholinga kudula. Podula, mpweya wothandiza umagwiritsidwa ntchito mwamsanga kuwombera slag pamtunda wachitsulo, kuti gawo locheka likhale losalala komanso lopanda burrs. Magesi othandizira osiyanasiyana amagwiritsidwa ntchito podula zinthu zosiyanasiyana. Ngati mpweya siwoyera kapena kupanikizika sikokwanira kuti pakhale kutuluka pang'ono, slag sidzawombedwa bwino ndipo ma burrs adzapangidwa.
Ngati workpiece ili ndi burrs, ikhoza kufufuzidwa kuchokera kuzinthu zotsatirazi:
1. Kaya chiyero cha gasi wodula sikokwanira, ngati sikokwanira, sinthani mpweya wothandiza wodula wapamwamba kwambiri.
2. Kaya malo owunikira a laser ndi olondola, muyenera kuyesa malo owunikira, ndikuwongolera molingana ndi momwe mukuwonera.
2.1 Ngati malo owonetsetsa ali apamwamba kwambiri, izi zidzawonjezera kutentha komwe kumatengedwa ndi mapeto apansi a workpiece kuti adulidwe. Pamene kuthamanga kwachangu ndi kuthamanga kwa mpweya wothandiza kumakhala kosalekeza, zinthu zomwe zimadulidwa ndi zinthu zomwe zimasungunuka pafupi ndi kavalo zimakhala zamadzimadzi pansi. Zinthu zomwe zimayenda ndikusungunuka pambuyo pa kuziziritsa zimamamatira kumunsi kwa workpiece mu mawonekedwe ozungulira.
2.2 Ngati malo akutsalira. Kutentha komwe kumakhudzidwa ndi kumapeto kwa pansi pazitsulo zodulidwa kumachepetsedwa, kotero kuti zinthu zomwe zili mumpata sizingathe kusungunuka kwathunthu, ndipo zotsalira zina zakuthwa ndi zazifupi zimamatira pansi pa bolodi.
3. Ngati mphamvu yotulutsa laser ndiyokwanira, yang'anani ngati laser ikugwira ntchito bwino. Ngati ndizabwinobwino, onani ngati mtengo wa batani lowongolera laser ndi wolondola ndikusintha moyenera. Ngati mphamvuyo ndi yaikulu kapena yaying'ono kwambiri, gawo lodula bwino silingapezeke.
4. Liwiro lodula la makina odulira laser ndilochedwa kwambiri kapena lachangu kwambiri kapena laling'ono kwambiri kuti likhudze zotsatira zodula.
4.1 Zotsatira za kuthamanga kwambiri kwa laser kudula chakudya pamtundu wodula:
Zitha kuyambitsa kulephera kudula ndi kuwotcha.
Madera ena amatha kudulidwa, koma madera ena sangadulidwe.
Zimapangitsa kuti gawo lonse lodula likhale lokhuthala, koma palibe madontho osungunuka omwe amapangidwa.
Kuthamanga kwa chakudya chodula kumathamanga kwambiri, kuchititsa kuti pepalalo lisathe kudulidwa mu nthawi, gawo lodula limasonyeza msewu wa oblique, ndipo madontho osungunuka amapangidwa m'munsimu.
4.2 Zotsatira za kuthamanga kwapang'onopang'ono kwa laser kudula pamtundu wodula:
Pangani pepala lodulidwa kuti lisungunuke kwambiri, ndipo gawo lodulidwa ndi lovuta.
Msoko wodula udzakulitsidwa molingana, kuchititsa kuti dera lonselo lisungunuke pamakona ang'onoang'ono ozungulira kapena akuthwa, ndipo zotsatira zabwino zodula sizingapezeke. Kutsika kwachangu kumakhudza mphamvu zopanga.
4.3 Momwe mungasankhire liwiro loyenera lodula?
Kuchokera pazitsulo zodulira, kuthamanga kwa liwiro la chakudya kumatha kuweruzidwa: Nthawi zambiri, zowombera zimafalikira kuchokera pamwamba mpaka pansi. Ngati zonyezimira zimapendekera, liwiro la chakudya limakhala lothamanga kwambiri;
Ngati zipserazo sizikufalikira komanso zazing'ono, ndipo zimafupikitsidwa pamodzi, zikutanthauza kuti liwiro la chakudya ndilochedwa kwambiri. Sinthani liwiro lodula moyenera, malo odulira amawonetsa mzere wokhazikika, ndipo palibe banga losungunuka pa theka lapansi.
5. Kuthamanga kwa mpweya
Mu njira yodulira laser, kuthamanga kwa mpweya wothandizira kumatha kutulutsa slag panthawi yodula ndikuziziritsa malo omwe amakhudzidwa ndi kutentha. Mipweya yothandiza imaphatikizapo mpweya, mpweya woponderezedwa, nayitrogeni, ndi mpweya wa inert. Pazinthu zina zachitsulo komanso zopanda zitsulo, gasi wolowera kapena mpweya woponderezedwa nthawi zambiri amagwiritsidwa ntchito, zomwe zimatha kuteteza zinthu kuti zisayaka. Monga kudula kwa aluminiyamu aloyi zipangizo. Pazinthu zambiri zachitsulo, gasi yogwira ntchito (monga mpweya) imagwiritsidwa ntchito, chifukwa mpweya ukhoza kutulutsa zitsulo pamwamba pazitsulo ndikuwongolera kudula bwino.
Pamene mpweya wothandiza wa mpweya ukukwera kwambiri, mafunde a eddy amawoneka pamwamba pa zinthuzo, zomwe zimafooketsa mphamvu yochotsa zinthu zosungunuka, zomwe zimapangitsa kuti ming'alu ikhale yowonjezereka komanso yodula pamwamba;
Kuthamanga kwa mpweya kumakhala kochepa kwambiri, zinthu zosungunula sizingathe kuphulika, ndipo pansi pazitsulozo zimamatira ku slag. Chifukwa chake, kuthamanga kwa gasi wothandizira kuyenera kusinthidwa panthawi yodula kuti mupeze mtundu wabwino kwambiri wodula.
6. Nthawi yayitali ya chida cha makina imapangitsa makinawo kukhala osakhazikika, ndipo amafunika kutsekedwa ndikuyambiranso kuti makinawo apume.
Ndi kusintha zoikamo pamwamba, ine ndikukhulupirira inu mosavuta zokhutiritsa laser kudula zotsatira.
