Momwe mungathanirane ndi burr yopangidwa ndi chitsulo chodula laser

Burr yomwe imapangidwa ndi laser cutting sheet sheet ndi vuto lofala kwambiri la njira yodulira, zomwe nthawi zambiri zimasonyeza kuti njira yodulira si yabwino kwambiri. Kuti muthetse vutoli mwadongosolo, ndikofunikira kuyang'ana ndikusintha kuchokera ku miyeso yosiyanasiyana monga zida, zipangizo, magawo a njira ndi mpweya wothandiza.

Malangizo oyendetsera bwino zinthu ndi njira zinazake

1. Konzani magawo a njira (ya chitsulo cha kaboni ndi zipangizo zina)

• Mphamvu ya laser: mphamvu yosakwanira ndi chimodzi mwa zifukwa zazikulu zomwe zimayambitsa ziphuphu. Kuonjezera mphamvu moyenera kungatsimikizire kuti chitsulocho chasungunuka kwathunthu. Komabe, ziyenera kudziwika kuti mphamvu yochulukirapo ingayambitse kuti mbaleyo ipse kapena kupachikika.
• Liwiro lodulira: Liwiro ndi lachangu kwambiri, mphamvu ya laser sikokwanira, zinthuzo sizisungunuka kwathunthu, ndipo zidzawombedwa ndi mpweya; ngati liwiro likuyenda pang'onopang'ono, kuyaka kudzakhala kwakukulu ndipo slag idzagwirana. Sinthani liwiro labwino kwambiri lomwe likugwirizana ndi mphamvu ndi makulidwe a mbale. Nthawi zambiri mutha kuyesa magawo kaye. Malo olunjika: Kulunjika kolakwika kumabweretsa kuchuluka kwa mphamvu kosakwanira. Yesani kuyang'ana kuti mupeze malo oyenera kwambiri makulidwe a mbale omwe alipo (nthawi zambiri mukadula chitsulo cha kaboni, kuyang'ana kumakhala pamwamba pa mbale kapena pansi pang'ono).

2. Onetsetsani kuti mpweya wothandiza uli bwino kwambiri (chinthu chofunikira kwambiri)

• Mtundu wa gasi ndi chiyero chake:
• Kudula chitsulo cha kaboni: Mpweya woyera kwambiri (≥ 99.95%) uyenera kugwiritsidwa ntchito. Mpweya woyera umagwira ntchito mu exothermic reaction, kuthandiza kutentha ndi kuwononga slag. Kusakwanira kwa chiyero kudzakhudza kwambiri khalidwe la kudula ndi gawo la oxide.

Kudula chitsulo chosapanga dzimbiri ndi aluminiyamu: nayitrogeni woyeretsedwa kwambiri (≥ 99.99%) kapena argon ziyenera kugwiritsidwa ntchito. Gwiritsani ntchito mpweya wopanikizika kwambiri kuti mutulutse chitsulo chosungunuka kuti muchepetse kusungunuka. Mpweya wodetsedwawo umayambitsa slag pansi.

• Kupanikizika kwa mpweya:
• Kudula chitsulo cha kaboni (ndi mpweya): kupanikizika sikuyenera kukhala kwakukulu kwambiri (nthawi zambiri 0.8-2bar). Kupanikizika kwambiri kudzaziziritsa kudulidwako, koma kuchepetsa mphamvu ya kuyaka, kupangika kwa ma burrs.
• Kudula chitsulo chosapanga dzimbiri/aluminiyamu (yokhala ndi nayitrogeni): Kupanikizika kuyenera kukhala kokwanira (nthawi zambiri mipiringidzo 10-20, kutengera makulidwe a mbale). Kupanikizika kosakwanira ndiye chifukwa chofala kwambiri cha kulephera kudula popanda burr, ndipo chitsulo chosungunuka sichingathe kuchotsedwa kwathunthu.
• Mkhalidwe wa Nozzle:
• Onetsetsani kuti nozzle yawonongeka kapena yotsekedwa ndi madzi. Nozzle yosweka ingayambitse kugwedezeka kwa mpweya.
• Onetsetsani ngati kukula kwa dzenje la nozzle kukugwirizana ndi makulidwe a plate ndi kuthamanga kwa mpweya. Ma plate okhuthala nthawi zambiri amafuna ma nozzle akuluakulu a orifice.
• Linganizani kuchuluka kwa mpweya ndi mutu wa laser. Kusinthasintha kwa kuchuluka kwa mpweya kudzapangitsa kuti mpweya uphulike ndi kupanga ma burrs mbali imodzi.

3. Yang'anani ndikusunga momwe zida zilili

• Kuyeretsa magalasi a kuwala: kuteteza magalasi, kuipitsa magalasi molunjika kudzachepetsa kwambiri mphamvu ya laser ndi kuwala kwa kuwala. Yang'anani nthawi zonse ndikutsuka kapena kusintha magalasi.
• Ubwino wa mtanda: kuwunikira mtanda nthawi zonse kuti muwonetsetse kuti njira yowunikira ndi yolondola komanso kuti cholinga chake ndi chozungulira.
• Kukhazikika kwa zida: Onetsetsani ngati njanji yowongolera zida zamakina ndi makina otumizira zinthu zili zokhazikika, ndipo ma burrs osakhazikika adzapangidwa mukagwedeza mofulumira kwambiri.

4. Yang'anani kwambiri pa nkhaniyo yokha

• Pamwamba pa pepala: Onetsetsani kuti pamwamba pa pepalalo mulibe dzimbiri, utoto kapena utoto, zomwe zingakhudze kuyamwa kwa laser ndi kukhazikika kwa kudula.
• Kapangidwe ka zinthu ndi ubwino wake: kapangidwe ka mbale kosakhala bwino kapena kosagwirizana kungayambitsenso kusinthasintha kwa zotsatira zodula.

Nkhawa Zapadera pa Mavuto a Burr mu Zipangizo Zosiyanasiyana

• Mbale yachitsulo cha kaboni (kudula mpweya): pansi pake pamakhala chitsulo cholimba komanso chophwanyika. Makamaka kuchokera ku kuyera kwa mpweya, malo olunjika, ndi liwiro la mphamvu.
• Mbale ya aluminiyamu yopanda chitsulo (kudula nayitrogeni): ma burrs apansi nthawi zambiri amakhala ofewa komanso atali chitsulo chosungunuka chosaphulika. Ntchito yoyamba ndikuwona ngati kuthamanga kwa nayitrogeni kuli kokwanira, ngati mpweya ndi woyera, komanso ngati nozzle ndi yoyenera.

Malangizo okhudza njira zothetsera mavuto mwadongosolo

1. Lembani ndi kubwerezanso:lembani mwatsatanetsatane mtundu wa mbale ya burr yomwe ilipo, makulidwe ake, ndi magawo onse a njira (mphamvu, liwiro, kuthamanga kwa mpweya, kuyang'ana, mtundu wa nozzle).

2. Kusintha kosinthika kamodzi:Sinthani gawo limodzi lokha panthawi imodzi (ndibwino kuyamba ndi mpweya woipa ndi malo ofunikira poyamba) kuti muyerekezere zodulidwa.

3. Kuthetsa mavuto mosavuta mpaka ovuta:

• Gawo 1: Yang'anani ndi kuyeretsa nozzle ndi lenzi.
• Gawo 2: Chongani kuyera kwa mpweya ndi kuthamanga kwake.
• Gawo 3: Konzani bwino malo oti muyang'ane.
• Gawo 4: Sinthani kufananiza kwa mphamvu ndi liwiro.
• Gawo 5: konzani njira yowunikira ndi kukhazikika kwa chipangizocho.

4. Khazikitsani laibulale yokhazikika ya magawo:Mukapeza magawo abwino kwambiri a mbale zamitundu yosiyanasiyana, makulidwe ndi zipangizo, zidzalembedwa kuti zikhale malangizo ogwiritsira ntchito.

Chidule:Cholinga chachikulu chothetsera vuto la ma laser cutting burrs ndi "kuonetsetsa kuti mphamvu yokwanira ikugwiritsidwa ntchito, ndikugwirizana ndi njira yokhazikika, yoyera, komanso yolondola ya mpweya kuti ichotse kusungunuka kwa madzi pakapita nthawi". Ndi vuto ladongosolo lomwe limafuna kuti wogwiritsa ntchito akhale woleza mtima komanso pang'onopang'ono afufuze ndikukonza bwino pogwiritsa ntchito njira zasayansi. Ngati njira zonse zomwe zili pamwambapa zawunikidwa ndipo vutoli likupitirira mutasintha, muyenera kulumikizana ndi wopanga zida kuti muwone ngati mphamvu yotulutsa laser kapena kuwala kwa magetsi yasintha.
