Iingcebiso zoshishino zokusikwa kweepleyiti ze-aluminium nge-pulse

Kwi-aluminium pulse fiber laser cutting, eyona nto iphambili kukulawula ngokuchanekileyo i-pulse output ye-laser (frequency, duty cycle, njl.njl.) kunye nokufudumala izinto rhoqo ukuze kuphuculwe i-heat input, ukuze kulinganiswe umgangatho wokusika kunye nokusebenza kakuhle phantsi kwe-reflectivity ephezulu kunye ne-thermal conductivity ye-aluminium.

Iiparameter zenkqubo eziphambili kunye neengcebiso zokwenza ngcono

Ezi zilandelayo ziingcebiso zokusika iipleyiti ze-aluminium ngokobukhulu obahlukeneyo, ezishwankathelwe kuphando lwezemfundo:

Iinjongo zeNkqubo

Ukusika okusemgangathweni ophezulu (nciphisa ukuxhoma kwe-slag, phucula ukugqitywa kwecandelo)

• Ubukhulu obusebenzayo: ubukhulu obuphakathi (umz. 4mm)
• Iingcebiso eziphambili zeparameter:
• Imo yeLaser: Imo yePulse iyacetyiswa
• Igesi encedisayo: I-nitrogen okanye i-Argon iyacetyiswa
• Amanqaku aphambili: yonyusa uxinzelelo lomoya oluncedisayo ukuze wonyuse amandla okuvuthuza i-slag; lawula igalelo lobushushu be-laser ukuze uphephe ukunyibilika kakhulu.

Ukusebenza kakuhle/ukusika iipleyiti ezityebileyo (ukusukela isantya okanye ukusika iipleyiti ezityebileyo)

• Ubukhulu obusebenzayo: ipleyiti ephakathi nenzima (umz. 10-15mm)
• Iingcebiso eziphambili zeparameter:
• Imo yeLaser: ingasebenzisa amaza aqhubekayo okanye ukubetha komjikelo ophezulu
• Igesi encedisayo: ioksijini ingazanywa
• Amanqaku angundoqo: Ukusabela kwe-oksijini exothermic kunokunyusa amandla kwaye kuphucule amandla okusika iipleyiti ezityebileyo; kodwa eli candelo liya kunyibilika libe rhabaxa, kwaye kufuneka ukucubungula okulandelayo.

Ukusika okuchanekileyo/okunephepha eliphezulu (kusetyenziswa kwiindawo ezichanekileyo ezifana neenqwelo-moya)

• Ubukhulu obusebenzayo: ipleyiti ebhityileyo (umz. 0.5-2mm)
• Iingcebiso eziphambili zeparameter:
• Imo yeLaser: imo ye-pulse ye-frequency ephezulu iyacetyiswa
• Igesi encedisayo: Kucetyiswa i-nitrogen
• Amanqaku aphambili: ukusetyenziswa kwesantya esiphezulu sokusika kunye noxinzelelo oluncedisayo olufanelekileyo; ukulawula igalelo lobushushu ukunciphisa indawo echaphazelekileyo kubushushu (ingalawulwa ngaphantsi kwe-20 m).

Isalathiso sepharamitha yomgangatho ophezulu ngokubanzi (i-aluminium alloy ye-4mm 2219 njengomzekelo)

Ukuze kufezekiswe iikhrayitheriya zokusika zenqanaba loku-1 (ukuxhonywa okuncinci kwe-slag kunye noburhabaxa obuphantsi), uphando lufumanise ukuba uluhlu olufanelekileyo lweeparameter zezi:

• Amandla eLaser:>4.5 kW
• Isantya sokusika: 3-4 m/min
• Uxinzelelo lomoya oluncedisayo: 1.3 MPa

Imingeni Engundoqo kunye neZisombululo Ezijoliswe Kuyo

Imingeni ephambili kunye nezisombululo zokusika i-aluminium zezi zilandelayo:

1. Ukukhanya okuphezulu

• Umngeni: I-Aluminium inomtsalane kakhulu kwi-laser, ingakumbi i-laser yefayibha ekufutshane ne-infrared, kwaye ayisebenzisi kakhulu amandla.
• Isisombululo: Sebenzisa i-laser enendlela "yokulwa nokukhanya"; sebenzisa i-pulse enamandla aphezulu ukuqhekeza izinto kwisigaba sokuqala sokusika, kwaye ukukhanya kuya kuncipha emva kokuba umngxuma wokuqala wenziwe.

2. Ukuqhuba ubushushu ngokukhawuleza kunye nokuxhonywa kwe-slag okulula

• Umngeni: Ubushushu buyaphela ngokukhawuleza, kwaye isinyithi esinyibilikisiweyo ezantsi kwesithintelo siyaqina size senze i-slag ekunzima ukuyisusa.
• Isisombululo: Xa kuthelekiswa ne-laser eqhubekayo, i-pulse laser inokulawula ubushushu ngokuchanekileyo; Yonyusa uxinzelelo lwegesi oluncedisayo (olufana ne-≥ 1.3MPa), iphucule amandla okucheba komoya ukuze kuphuphume i-slag; Lungiselela indawo yokugxila, ngokuqhelekileyo ngaphantsi komphezulu wepleyiti.

3. Ukusika umgangatho wecandelo kunye neemfuno zenkqubo ezilandelayo

• Umngeni: Icandelo lokusika liya kwenza umaleko onyibilikisiweyo. Ukuba kufuneka ukuwelda okulandelayo, kuya kuchaphazela ukuvuleka kweweld.
• Isisombululo: Ukuba kufuneka ukuwelda emva kokusika, inkqubo kufuneka ilawulwe ngokungqongqo, kwaye ubukhulu bomaleko wokunyibilikisa umthungo wokusika kufuneka bulawulwe ngaphantsi kwe-136μm ukuze kuncitshiswe ngempumelelo ukuqina kwe-weld.

Uluhlu lwezinto eziphambili zokusebenza kwemizi-mveliso

• Ukukhetha igesi:ukufunwa kokusika okusemgangathweni okuphezulu okungaxutywanga (ingakumbi imfuneko elandelayo yokuwelda), nika phambili i-nitrogen okanye i-argon ecocekileyo kakhulu. Ioksijini inokuvavanywa xa kulandelwa ubukhulu kunye nesantya sokusika kwaye ukuxutywa kwecandelo akuyongxaki.
• Ulandelelwano lokulungisa iimpazamo zeparameter:Kucetyiswa ukuba kulungiswe ezinye izinto eziguquguqukayo kwaye kulungiswe le ngxaki ngolu hlobo: indawo yokugxila → uhlobo lwegesi oluncedisayo kunye noxinzelelo → amandla elaser → isantya sokusika → iiparameter zepulse (ukuba kusetyenziswa imo yepulse).
• Izixhobo kunye nokhuseleko:ukuqinisekisa ukuba i-laser inamandla okujongana nezinto ezikhazimlayo kakhulu; Xa usika ipleyiti ye-aluminiyam, ukutshiza kwentlantsi kuba namandla ngakumbi. Kubalulekile ukuqinisekisa ukuba inkqubo yokususa uthuli iyasebenza kwaye izixhobo kunye nabasebenzi bakhuselekile.
• Ukusika nokuhlola uvavanyo:Ukusika uvavanyo kufuneka kwenziwe ngaphambi kokusika ngokusesikweni. Ukuze uhlole umgangatho, nceda ujonge oku: ukujongwa ngokubonakalayo kwe-slag exhonywe ezantsi; uburhabaxa becandelo lokuqonda indlela yoqhagamshelwano; ukulinganiswa kwe-microscope yobukhulu bomaleko obuye bancibilikiswa (ukuba kukho iimfuno eziphezulu).

Isishwankathelo kunye neeNgcebiso zokugqibela

Isiseko sepleyiti ye-aluminiyam yokusika i-laser yefayibha eshukumayo yi"Ulawulo lobushushu oluchanekileyo"Le ndlela ilandelayo iyacetyiswa:

1. Eyona nto ibalulekileyo:Okokuqala misela ukuba injongo yakho ephambili kukukhetha icandelo, ukusebenza kakuhle kokusika okanye ukusebenza kakuhle kokuwelda.

2. Ngokwesixa seeparameters eziphambili:jonga kwitheyibhile yangaphambili, ngokobukhulu kunye nokubaluleka kweplate yakho ye-aluminium, misela imo yelaser yokuqala kunye nohlobo lwegesi.

3. Ukulungisa iimpazamo nokuqinisekisa:Ukulungisa iimpazamo kakuhle kwenziwa ngokujikeleze uxinzelelo lomoya oluncedisayo kunye nesantya sokusika, kwaye ukuqinisekiswa kokusikwa kwesilingo kwenziwa ngokungqongqo.
