Izakhono zokusika umphezulu oqaqambileyo nge-laser

Ukusebenzisa umatshini wokusika i-fiber laser ukusika izinto ezikhanyayo (ezifana nentsimbi engagqwaliyo yesipili, i-aluminium ekhazimlayo, ubhedu, ubhedu, njl.njl.) kuneeyantlukwano ezibalulekileyo kunye neenzuzo ezinkulu ekusebenziseni i-CO₂ laser yendabuko, kodwa ikwafuna izakhono ezikhethekileyo ukufumana iziphumo ezilungileyo nokuqinisekisa ukhuseleko.

Umgaqo oyintloko: Ububanzi be-laser yefayibha yi-1.06 microns, kwaye izinga lokufunxwa kwezinto zesinyithi liphezulu kakhulu kunele laser ye-CO₂ ene-10.6 microns.Oku kuthetha ukuba i-fiber laser ayinakwenzeka ukuba ibonakale, ukusetyenziswa kwamandla kuphezulu, kwaye umngcipheko womonakalo wokubonakaliswa kwezixhobo uncitshisiwe kakhulu. Kodwa oko akuthethi ukuba akukho mingeni.

Ezi zilandelayo ziindlela ezicacileyo zokusika umphezulu ezenzelwe ngokukodwa umatshini wokusika i-fiber laser:

Iingenelo eziphambili kunye neZakhiwo

Okokuqala, kuyacaca ukuba kwi-stainless steel eqaqambileyo ye-304, oomatshini bokusika i-fiber laser banamhlanje banokusika ngokuthe ngqo ngaphandle kokulungiswa okuntsonkothileyo njenge-CO₂ laser, kwaye umngcipheko wokubonakalisa uphantsi kakhulu. Ubunzima bukwindlela yokufumana umphezulu wokusika "ongenasiphako" ukuthintela ukukrweleka kunye ne-oxidation yomphezulu.

Izakhono eziphambili kunye nokuphuculwa kweeParameter

1. Ukukhethwa kwegesi kunye nolawulo loxinzelelo (eyona nto ibalulekileyo)

• Ukusikwa kwe-nitrogen ecocekileyo/ukucoca okuphezulu
• Injongo: Ukufumana umphezulu oqaqambileyo ongenawo umbala we-oxidation, umbala omhlophe wesilivere okanye wendalo.
• Iimfuno zoxinzelelo: Kufuneka uxinzelelo lomoya oluphezulu kakhulu (ngesiqhelo i-> 1.2MPa okanye ngaphezulu). I-nitrogen enoxinzelelo oluphezulu ingasusa ngokukhawuleza isinyithi esinyibilikisiweyo, ukuthintela ukubola kwayo kumphezulu wokusika, ngelixa ipholisa umthungo wokusika.
• Iimfuneko zoBumsulwa: Sebenzisa i-nitrogen engama-99.99% okanye ngaphezulu ukuze uphephe ukungcola kwe-oksijini okubangela ukuba umphezulu osikiweyo unyibilike kwaye ujike ube tyheli kwaye ube mnyama.
• Ukusika ioksijini:
• Isebenza kuphela ekufuneni isantya sokusika, kwaye ungayikhathaleli indawo yokusika yomaleko we-oxide emnyama. Kwizinto zokusebenza ezifuna ukugcina inkangeleko "yomphezulu oqaqambileyo", azisetyenziswa rhoqo.

2. Ukukhetha i-nozzle kunye nokulawula ukuphakama

• Sebenzisa umlomo onamaleko amabini/odibeneyo: umlomo onamaleko amabini (njenge-HighSpeed, umlomo onamaleko aphantsi) unokwenza ukuhamba komoya okuzinzileyo nokudibeneyo, amandla okususa i-slag aqine ngakumbi, afaneleke ngakumbi ekusikeni umphezulu okhanyayo we-nitrogen ocinezelweyo.
• Ukuvulwa kwempumlo: ngokwendlela ekhethiweyo ngayo ipleyiti etyebileyo, kudla ngokusetyenziswa ukuvulwa okukhulu kancinci (okufana ne-φ2.0, φ3.0) ukuqinisekisa ukuhamba komoya okwaneleyo.
• Indawo yokugxila: Zama ukulungisa ukugxila kancinci ezantsi (nzulu kwiphepha) ukuze ufumane ukusika okuthe nkqo nokugudileyo.
• Ukuphakama kokusika: gcina ubude bokulandelela obungaguqukiyo nobuchanekileyo ukuqinisekisa ukuhamba komoya okuzinzileyo.

3. Ukulungiswa kweeparameter zeLaser

• Amandla: Ukusebenzisa amandla aphezulu ngesantya esiphezulu kunokunciphisa indawo echaphazelekileyo bubushushu kwaye kuthintele ukunyibilika kakhulu okanye ukutyheli komphetho osikiweyo.
• Ukuphindaphinda: Ukwandisa ukuphindaphinda kwe-pulse (njenge-500-1000Hz okanye ngaphezulu) kunokwenza umgca wokusika ube buthathaka kwaye ubushelelezi.
• Umjikelo womsebenzi: lungisa umjikelo womsebenzi ofanelekileyo, phantsi kwengcamango yokuqinisekisa uzinzo lokusika, ukuze ufumane iiparameter ezilungileyo zokugqiba.
• Isantya sokusika: kwimeko yokuqinisekisa ukuba ukusika kuyanqumla, zama ukusebenzisa isantya sokusika esikhawulezayo ukunciphisa ukuqokelelana kobushushu.

4. Ulawulo loGxilo

• Kwenziwe uvavanyo lokugxila ukuze kufunyanwe indawo efanelekileyo yokugxila kwizinto ezikhanyayo kunye nobukhulu. Ngokwesiqhelo ukugxila okungalunganga kancinci (ukugxila kwelaser kungaphakathi kwipleyiti) kunceda ukufumana icandelo elithe nkqo elingcono.

Izinto ezikhethekileyo eziqwalaselwayo kwizinto ezahlukeneyo ezikhazimlayo

isibuko sentsimbi engatyiwayo:

• Umphezulu wokuqala okhuselayo: ukusetyenziswa kwefilimu ekhethekileyo yokukhusela esemgangathweni ophezulu yokusika nge-laser! Le yeyona ndlela isebenzayo yokuthintela ukuchitheka okubangelwa kukusika kunye nomphezulu wetafile yomatshini ekukrweleni umphezulu wesibuko.
• Emva kokusikwa, ifilimu ekhuselayo ingakrazulwa lula ukuze ifumane umphezulu ogudileyo.

Ii-aluminium kunye nee-aluminium alloys (ingakumbi i-gloss ephezulu):

• Umngcipheko wokubonakalisa: Ukubonakalisa kwe-aluminium ecocekileyo kunye ne-aluminium ye-silicon ephezulu kusephezulu. Nangona umngcipheko uphantsi kune-CO₂, ii-laser ze-fiber ezinamandla aphezulu (umz., ii-watts ezili-10,000 okanye ngaphezulu) kusafuneka ziqaphele impembelelo enokubakho yokubonakalisa ngasemva kwiindawo zangaphakathi zentloko ye-fiber xa zisikwa.
• Iiparameters: I-Aluminium iqhuba ubushushu ngokukhawuleza, ifuna amandla aphezulu kunye nesantya esikhawulezayo. Sebenzisa i-nitrogen ecocekileyo kwaye unokufuna ukongeza inani elincinci le-argon ukuze ufumane icandelo elikhanyayo.
• Ukuxhoma i-slag: Ukusikwa kwe-aluminium kulula ukuvelisa ukuxhoma i-slag esezantsi, ekufuneka koyiswe ngokuphucula uxinzelelo lomoya kunye nokugxila.

ubhedu nobhedu:

• Ukukhanya okuphezulu: Ubhedu olucocekileyo (ubhedu) yenye yezona metali zikhanyayo kwaye ikwayingozi kwi-fiber lasers. Soloko uqala uvavanyo ngamandla aphantsi.
• Ingxaki yokufunxa: I-laser yefayibha eluhlaza (ubude be-wavelength 515nm) ingasetyenziswa. I-Copper inezinga eliphezulu kakhulu lokufunxa ukukhanya okuluhlaza. Lukhetho olufanelekileyo lokusika i-copper, kodwa izixhobo zibiza kakhulu.
• I-Brass: i-zinc, umphunga we-zinc uya kuveliswa xa kusikwa, icandelo lilula ukulifaka mnyama. I-nitrogen enoxinzelelo oluphezulu iyafuneka kwaye iiparameter ziyalungiswa.

Iingcebiso zokhuseleko kunye nokusebenza

1. Uvavanyo lokuqala:Kwizinto ezikhazimlayo kakhulu (ubhedu olucocekileyo, i-aluminium ecocekileyo), xa kusikwa okokuqala, ii-scrap zingasetyenziswa kuqala, kwaye zivavanywe ngamandla aphantsi ukujonga imeko yokusika kunye nempendulo yomatshini.

2. Ukuhlolwa kwezixhobo:Qinisekisa ukuba intloko yelaser yomatshini wakho wokusika ilaser yefayibha ixhotyiswe ngesixhobo sokukhusela ukubonakaliswa (njenge-back reflection isolator). Uninzi lweemashini ze-fiber optic zanamhlanje ezisebenzisa amandla aphakathi ukuya kwaphezulu ziza ngokwesiqhelo.

3. Ukucoca kunye nokugcinwa:

• Coca umphezulu wento ngeoyile phambi kokuba uyinqumle.
• Jonga rhoqo kwaye ucoce umlomo kwaye ukhusele ilensi. Igesi enoxinzelelo oluphezulu ngexesha lokusika umphezulu okhanyayo inokuphakamisa uthuli kwaye iluncamathisele kwilensi ngokulula.

4.Ukusika uvavanyo kunye nethala leencwadi leeparameter:Misela "ilayibrari yepharamitha yokusika umphezulu eqaqambileyo" yezixhobo ezahlukeneyo, ubukhulu obahlukeneyo kunye neemfuno ezahlukeneyo zomphezulu, kwaye wenze uqinisekiso lokusika oluncinci rhoqo xa izinto zitshintshwa.

Amanqaku esishwankathelo

Isiphelo:Kwi-laser zefayibha, isiseko sokusika izinto ezikhanyayo zomphezulu sitshintshile ukusuka “kwindlela yokuthintela umonakalo wokubonakalisa” ukuya “kwindlela yokwenza ngcono inkqubo yokufumana umphezulu ogqibeleleyo wokusika nokukhusela ukubonakala kwezinto”. Ngokudibanisa “uhlengahlengiso oluhle lweeparameter zokhuseleko lwefilimu yokusika umphezulu we-nitrogen ecocekileyo kakhulu”, izinto zokusebenza ezikhanyayo zomgangatho ophezulu zinokucutshungulwa ngokuzinzileyo nangokufanelekileyo.
