Ubale Pakati pa Laser Cutting Focus ndi Burrs

Malo ofunikira pakudula kwa laser ali ndi ubale wolunjika komanso wotsimikizika ndi mapangidwe a burr.Mwachidule, malo ofunikira amakhudza mwachindunji kugawa kwa mphamvu kwa mtanda mkati mwa chinthucho, motero amatsimikiza mtundu wa kerf, kugwira ntchito bwino kwa kutulutsa zinthu zosungunuka, komanso ngati ma burrs amatha kupangidwa.Maubwenzi afotokozedwa mwatsatanetsatane pansipa.

Mfundo Yoyambira: Momwe malo ofunikira amakhudzira njira yodulira

Mfundo yodulira pogwiritsa ntchito laser ndi kuunikira ntchitoyo ndi kuwala kwa laser komwe kumawonjezera mphamvu, zomwe zimapangitsa kuti isungunuke kapena kusungunuka mwachangu, pomwe辅助mpweya (monga mpweya kapena nayitrogeni) umachotsa zinthu zosungunuka kuti zipange chodulidwacho.

Kuyang'ana Kwambiri: Malo omwe mphamvu ya kuwala kwa laser imakhala yochuluka kwambiri ndipo kukula kwake ndi kochepa kwambiri.

Malo olunjika: amatanthauza malo omwe pali malo olunjika poyerekeza ndi malo ogwirira ntchito. Amagawidwa m'magulu atatu:

1. Kuchotsa chidwi chabwino: Malo ofunikira ali pamwamba pa malo ogwirira ntchito.

2. Kuchotsa zinthu molakwika: Malo ofunikira ali pansi pa malo ogwirira ntchito.

3. Zero defocus: Malo ofunikira ali pamalo pomwe ntchito imapangidwira.

Ubale weniweni pakati pa malo ofunikira ndi burr

Mtundu wa burr ndi wakuti kusungunuka kotsala, komwe sikunaphulitsidwe konse, kumakhazikikanso pansi pa chodulidwacho. Malo ofunikira amakhudza burr makamaka pokhudza mawonekedwe odulidwa ndi mphamvu ya mpweya.

1. sichikudziwika bwino (yang'anani pa ntchito yogwirira ntchito)

• Kugawa mphamvu: Mtanda ukalowa mu chinthucho, umasiyana, ndipo kuchuluka kwa mphamvu kumachepa pang'onopang'ono kuchokera pamwamba mpaka pansi. Mphamvuyo imakhala yamphamvu kwambiri pamwamba ndipo imakhala yofooka kwambiri pansi.
• Kapangidwe ka chocheka: kosavuta kupanga chocheka chooneka ngati V chokhala ndi chapamwamba chachikulu ndi chapansi chopapatiza.

Zotsatira pa burr:

• Chifukwa cha mphamvu yochepa pansi, pansi pa zinthuzo singathe kusungunuka kwathunthu kapena kusinthidwa kukhala mpweya.
• Kuthamanga kwa mpweya wothandiza kumawonjezeka pansi pang'ono, koma mphamvu yopumirayo singakhale yokwanira kuchotsa ndikutulutsa kusungunuka kwa viscous.

Zotsatira: N'zosavuta kupanga ma burrs ambiri ouma pansi. Ichi ndi chimodzi mwa zifukwa zomwe zimayambitsa ma burrs.

2. Kuchepetsa kukhazikika (kuyang'ana pansi pa ntchito)

• Kugawa mphamvu; mtandawo umalumikizana mkati mwa chinthucho, ndipo kuchuluka kwa mphamvu kumafika pamwamba kwambiri pakati kapena pansi pa chinthucho.
• Kapangidwe ka chocheka: kosavuta kupanga chocheka chooneka ngati ng'oma m'chiuno chokhala ndi chapamwamba, chapansi ndi chapakati chopapatiza.

Zotsatira pa burr:

• Ubwino wake ndi wakuti mphamvu ya pansi si yokwanira ndipo zinthuzo zimatha kusungunuka bwino kwambiri.
• Komabe, pakati pa chochekacho ndiye paliponse, zomwe zingayambitse kuti mpweya ufalikire apa ndikufooketsa mphamvu yopumira ikafika pansi.
• Ngati magawowo sakugwirizana bwino, kusungunukako kungamatirirebe pansi chifukwa cha mzere wosayera.

Zotsatira: Poyerekeza ndi defocus yabwino, mkhalidwe wa burr udzasintha, koma burr yofewa pang'ono ingapangidwebe. Pa kudula mbale yokhuthala, defocus yoipa nthawi zina imagwiritsidwa ntchito kuonetsetsa kuti pansi padulidwa.

3. Kusayang'ana kwambiri pamwamba pa chinthu chogwirira ntchito kapena kuzama kwinakwake (kuyang'ana kwambiri pamwamba pa chinthu chogwirira ntchito kapena kuzama kwina)

• Kugawa mphamvu: Malo amphamvu kwambiri ali pamwamba pa workpiece, yomwe ndi yabwino kwambiri podula mbale zopyapyala. Pa mbale zokhuthala, nthawi zambiri pamafunika malo "oyang'ana bwino kwambiri", kutanthauza kuti, kuyang'ana kumapita mozama kwambiri mkati mwa zinthuzo (mwachitsanzo, 1/3 ya makulidwe a mbale) kuti mphamvu ikhale yofanana pamwamba ndi pansi.
• Kapangidwe ka chocheka: chocheka choyima bwino kwambiri, chofanana.

Zotsatira pa burr:

• Kugawa mphamvu m'dera lonse lodulidwa ndi kofanana, ndipo zinthuzo zimatha kusungunuka mosalekeza komanso mokhazikika.
• Kudula kofananako kumapereka njira yosalala ya mpweya wothandiza, womwe ungathe kunyamula mphamvu zokwanira zoyendetsera mpweya kuti utulutse bwino kusungunuka kuchokera pansi.

Zotsatira: Iyi ndi njira yabwino kwambiri yopezera ma burr kapena ma burr ochepa. Kusungunukako kunachotsedwa "moyera" popanda zotsalira.

Chidule ndi Kufanizira

Mukhoza kumvetsa motere:

• Sili bwino kwenikweni: ngati "chisel chopanda pake", pamwamba pake ndi polimba kwambiri, koma pansi pake ndi potopetsa, imatha "kupukuta" nsaluyo, ndikusiya yopyapyala.
• Kuchotsa zinthu molakwika: Monga "kuphulika" mkati mwa chinthucho, ngakhale kuti chingaphulike, njira yotulukira singakhale yoyera ndipo ingatulutse zinyalala zina.
• Cholinga chabwino kwambiri: Monga "chogwirira chakuthwa", chodulidwa bwino kuyambira pamwamba mpaka pansi, choyera komanso choyera.

Buku Lophunzitsira: Momwe Mungasinthire Kuyang'ana Kwambiri Kutengera ndi Zolakwika

Pakugwira ntchito kwenikweni, ngati ma burrs apezeka, njira zotsatirazi ziyenera kutsatiridwa kuti muwone ndikukonza:

1. Yang'anani mawonekedwe a burr:

• Pali ma burrs ambiri olimba komanso opindika pansi: mwina pansi pake sipanadulidwe chifukwa cha kusayang'ana bwino (kuyang'ana kwambiri) kapena mphamvu yosakwanira/liwiro lothamanga kwambiri. Kuyang'ana kuyenera kusinthidwa pansi.
• Pansi pali burr wofewa, wosavuta kugwa ngati ndevu: ukhoza kukhala negative defocus (focus ndi yotsika kwambiri) kapena mpweya wosakwanira/mpweya wosayera womwe umapangitsa kuti kusungunuka kusatuluke. Mungayesere kukonza focus mmwamba ndikuyang'ana magawo a mpweya.

2. Kuyesa ndi kuwunikira bwino:

• Gwiritsani ntchito chida cholozera malo kuti mudziwe bwino malo olunjika pa zero.
• Mu pulogalamu yodulira, kusintha kwa ± nthawi zambiri kumachitika potengera mfundo ya 0. Chitani mayeso owunikira (monga +1 mpaka -3 mu masitepe 0.5), dulani chithunzi chomwecho, kenako onani malo omwe ali ndi kudula kosalala komanso kocheperako. Malo awa ndiye malo abwino kwambiri opangira zinthu zamakono, makulidwe ndi zida.

OZinthu zazikulu zomwe zimakhudza zolakwika (zoyenera kuganiziridwa mogwirizana)

Kuyang'ana kwambiri si chinthu chokhacho ndipo chiyenera kukonzedwa bwino mogwirizana ndi magawo ena a njira:

Mpweya wothandiza:

Kupanikizika:Kupanikizika kosakwanira sikungachotse bwino matope; kupanikizika kwambiri kungayambitse kugwedezeka, komwe kungasokoneze kukhazikika.

Chiyero:Makamaka podula chitsulo chosapanga dzimbiri, ndikofunikira kugwiritsa ntchito nayitrogeni woyeretsedwa kwambiri (99.99% kapena kuposerapo). Mpweya wotsalira umapanga slag yosungunuka ndipo umawonjezera ma burrs.

Kudula liwiro:Liwiro lake ndi lachangu kwambiri, mphamvu zomwe zimalowa sizikwanira, ndipo zinthuzo sizinadulidwe mokwanira, zomwe zimapangitsa kuti ma burrs apansi apangidwe; liwiro lake ndi lochedwa kwambiri, kuchotsedwa kwakukulu kwa ma burrs, kudula kosalala, ndi ma burrs amathanso kupangidwa.

Mphamvu ya laser:mphamvu ndi liwiro kuti zigwirizane. Mphamvu ndi yochepa kwambiri moti sitingathe kuidula.

Mphuno:Kutseguka, kutalika ndi kupingasa kwa nozzle kumakhudza mwachindunji momwe mpweya umayendera. Kusagwirizana ndi chifukwa chofala cha kudulidwa kosagwirizana komanso ma burrs.

Nkhani yokha:kapangidwe ka zinthuzo, momwe pamwamba pake palili (monga ngati pali dzimbiri, mafuta) zimakhudzanso.

Malo olunjika ndiye gawo lalikulu losinthira kuti liwongolere kudula kwa laser.Malo abwino olunjika amapanga kudula kowongoka komanso kosalala ndipo kumalola mpweya wothandizira kutulutsa bwino kusungunuka. Mukakumana ndi vuto la burr, choyamba muyenera kuchita mayeso olunjika kuti mupeze focus yabwino kwambiri, kenako gwirizanitsani kuti musinthe magawo ena monga gasi ndi liwiro kuti mupeze zotsatira zabwino zodula zopanda burr.
