Ukusika kweLaserisicelo
I-axial flow ekhawulezayo ye-CO2 lasers isetyenziswa kakhulu ukusika i-laser yezixhobo zetsimbi, ngakumbi ngenxa yomgangatho wabo olungileyo we-beam. Nangona ukubonakaliswa kwezona zintsimbi ezininzi ukuya kwimiqadi yelaser ye-CO2 kuphezulu kakhulu, ukubonakaliswa komphezulu wesinyithi kwindawo yobushushu begumbi kuyenyuka ngokunyuka kwamaqondo obushushu kunye neqondo le-oxidation. Emva kokuba indawo yesinyithi yonakaliswe, i-reflectivity yensimbi isondele kwi-1. Ukusika i-laser yensimbi, amandla aphezulu aphezulu ayimfuneko, kwaye kuphela i-CO2 lasers yamandla aphezulu analo mqathango.
1. Ukusika i-laser yezinto zensimbi
1.1 I-CO2 yokusika i-laser eqhubekayo Iiparamitha eziphambili zenkqubo ye-CO2 yokusika i-laser eqhubekayo iquka amandla e-laser, uhlobo kunye noxinzelelo lwegesi encedisayo, isantya sokusika, indawo yokugxila, ubunzulu be-focal kunye nokuphakama kwe-nozzle.
(1) Amandla eLaser Amandla eLaser anempembelelo enkulu ekusikeni ubukhulu, isantya sokusika kunye nobubanzi bokusika. Xa ezinye iiparitha zihlala zihlala, isantya sokusika siyancipha ngokunyuka kwe-plate yokusika ubukhulu kunye nokwandisa ngokunyuka kwamandla e-laser. Ngamanye amazwi, amandla amakhulu elaser, kokukhona ipleyiti inokusikwa, isantya esikhawulezayo sokusika, kwaye isikhulu kancinane ububanzi bokusika.
(2) Uhlobo kunye noxinzelelo lwegesi encedisayo Xa usika insimbi ye-carbon ephantsi, i-CO2 isetyenziswe njengegesi encedisayo ukusebenzisa ukushisa kwe-iron-oxygen combustion reaction ukukhuthaza inkqubo yokusika. Isantya sokusika siphezulu kwaye umgangatho wokusika ulungile, ngakumbi ukusika ngaphandle kwe-slag encangathi kungafumaneka. Xa usika insimbi engenasici, i-CO2 isetyenziswa. I-Slag ilula ukunamathela kwindawo engezantsi ye-incision. I-CO2 + N2 igesi edibeneyo okanye i-double-layer gas flow flow idla ngokusetyenziswa. Uxinzelelo lwegesi encedisayo lunempembelelo ebalulekileyo kwisiphumo sokusika. Ukunyusa ngokufanelekileyo uxinzelelo lwegesi kunokunyusa isantya sokusika ngaphandle kwe-slag enamathelayo ngenxa yokunyuka kwesantya sokuhamba kwegesi kunye nokuphuculwa kwamandla okususwa kwe-slag. Nangona kunjalo, ukuba uxinzelelo luphezulu kakhulu, umphezulu osikiweyo uba rhabaxa. Isiphumo soxinzelelo lweoksijini kumndilili woburhabaxa bomphezulu wokusikeka uboniswe kumzobo ongezantsi.
Uxinzelelo lomzimba lukwaxhomekeke kubukhulu beplate. Xa usika intsimbi ephantsi yekhabhoni nge-laser ye-1kW CO2, ubudlelwane phakathi koxinzelelo lwe-oksijini kunye nobukhulu beplate buboniswe kumzobo ongezantsi.
(3) Ukusika isantya Ukusika isantya kunempembelelo ebalulekileyo kumgangatho wokusika. Phantsi kweemeko ezithile zamandla e-laser, kukho amaxabiso aphezulu kunye asezantsi abalulekileyo ahambelana nesantya esilungileyo sokusika xa usikwa intsimbi ephantsi yekhabhoni. Ukuba isantya sokusika siphezulu okanye siphantsi kunexabiso elibalulekileyo, ukunamathela kwe-slag kuya kwenzeka. Xa isantya sokusika sicotha, ixesha lesenzo sokushisa kwe-oxidation kwi-cut cut yandiswa, ububanzi bokusika buyanda, kwaye indawo yokusika iba buhlungu. Njengoko isantya sokusika sikhula, ukusika kuya kuba kuncipha kude kube ububanzi bendawo ephezulu bulingane nobubanzi bendawo. Ngeli xesha, i-incision imile kancinci, ibanzi phezulu kwaye imxinwa ezantsi. Njengoko isantya sokusika siqhubeka sikhula, ububanzi bendawo engaphezulu buyaqhubeka buba buncinci, kodwa indawo esezantsi yokusikwa iba banzi kwaye ibe yimilo ye-wedge eguqulweyo.
(5)Ubunzulu bojoliso
Ubunzulu bengqwalasela bunempembelelo ethile kumgangatho wokusika kunye nesantya sokusika. Xa usikwa iipleyiti zentsimbi ezinkulu, kufuneka kusetyenziswe umqadi obunzulu obugxininisekileyo; xa usika amacwecwe amancinci, kufuneka kusetyenziswe i-boam enobunzulu obuncinci.
(6)Ubude bomlomo
Ubude bombhobho bubhekiselele kumgama osuka ekupheleni kombhobho werhasi oncedisayo ukuya kumphezulu womsebenzi. Ukuphakama kwe-nozzle kukhulu, kwaye ukukhawuleza kwe-airflow ekhutshiweyo yokuncedisa kulula ukuguquguquka, okuchaphazela umgangatho wokusika kunye nesantya. Ke ngoko, xa kusikwa i-laser, ubude bombhobho buncitshiswa ngokubanzi, buqhele ukuba yi-0.5 ~ 2.0mm.
① Imiba yeLaser
a. Ukwandisa amandla e-laser. Ukuphuhlisa iilaser ezinamandla ngakumbi yindlela ethe ngqo nesebenzayo yokunyusa ukutyeba kokusika.
b. Ukuqhubekeka kwe-Pulse. Iilaser ezipholileyo zinamandla aphezulu kakhulu kwaye zinokungena kwiipleyiti zentsimbi ezishinyeneyo. Ukusebenzisa i-high-frequency, i-pulse-width-pulse-width pulse laser cutting technology inokusika iipleyiti zentsimbi ezishinyeneyo ngaphandle kokunyusa amandla e-laser, kwaye ubungakanani bokusika buncinci kunobo bokusika i-laser eqhubekayo.
c. Sebenzisa iilaser ezintsha
②Inkqubo yokubona
a. Inkqubo ye-adaptive optical system. Umahluko ukusuka kwi-laser yendabuko yokusika kukuba ayifuni ukubeka ingqalelo ngaphantsi kwendawo yokusika. Xa indawo ekugxilwe kuyo iguquguquka ukuya phezulu nasezantsi ngeemilimitha ezimbalwa ecaleni kobungqingqwa becala lepleyiti yentsimbi, ubude bojoliso kwinkqubo yokukhanya eguquguqukayo buya kutshintsha ngokutshintsha kwendawo ekugxilwe kuyo. Ukunyuka nokuhla kweenguqu kubude bogxininiso lungqamana nentshukumo ehambelanayo phakathi kwelaser kunye nesixhobo sokusebenza, esibangela ukuba indawo ekugxilwe kuyo itshintshe phezulu nasezantsi ecaleni kobunzulu bomsebenzi. Le nkqubo yokusika apho ugxininiso lwesikhundla lutshintsha kunye neemeko zangaphandle kunokuvelisa ukusika okuphezulu. Ukungalungi kwale ndlela kukuba ubunzulu bokusika bukhawulelwe, ngokuqhelekileyo akukho ngaphezu kwe-30mm.
b. Itekhnoloji yokusika iBifocal. I-lens ekhethekileyo isetyenziselwa ukugxila kwi-beam kabini kwiindawo ezahlukeneyo. Njengoko kubonisiwe kuMzobo 4.58, i-D yi-diameter yecandelo eliphakathi lens kunye nobubanzi bomda we-lens. I-radius ye-curvature embindini we-lens inkulu kunendawo ejikelezileyo, yenza ukugxila kabini. Ngethuba lenkqubo yokusika, ugxininiso oluphezulu lubekwe kwindawo ephezulu ye-workpiece, kwaye ugxininiso oluphantsi lubekwe kufuphi nomgangatho ophantsi we-workpiece. Le teknoloji ekhethekileyo yokusika i-laser ene-double-focus ineenzuzo ezininzi. Ukusika intsimbi ethambileyo, ayinakugcina kuphela i-laser ye-high-intensity beam kumphezulu ophezulu wesinyithi ukuhlangabezana neemeko ezifunekayo ukuze izinto zivutha, kodwa nokugcina i-laser beam ephezulu kufuphi nomgangatho ophantsi wentsimbi. ukuhlangabezana neemfuno zokutshisa. Isidingo sokuvelisa ukusikwa okucocekileyo kulo lonke uluhlu lobunzima bezinto eziphathekayo. Le teknoloji yandisa uluhlu lweeparamitha zokufumana ukusika okuphezulu. Umzekelo, usebenzisa i-3kW CO2. i-laser, ubukhulu bokusika obuqhelekileyo bunokufikelela kuphela kwi-15 ~ 20mm, ngelixa ubuninzi bokusika usebenzisa iteknoloji yokusika i-double focus inokufikelela kwi-30 ~ 40mm.
③Nozzle kunye nokuhamba komoya okuncedisayo
Yila ngokufanelekileyo umbhobho wokuphucula iimpawu zentsimi yokuhamba komoya. Idayamitha yodonga lwangaphakathi lombhobho we-supersonic uqala ukucutheka kwaye emva koko uyanda, nto leyo enokuvelisa ukuhamba komoya okuphezulu kwindawo yokuphuma. Uxinzelelo lonikezelo lomoya lunokuba phezulu kakhulu ngaphandle kokuvelisa amaza othusayo. Xa usebenzisa i-supersonic nozzle yokusika i-laser, umgangatho wokusika nawo ufanelekile. Kuba uxinzelelo lokusika lombhobho we-supersonic kumphezulu womsebenzi uzinzile, ilungele ukusika i-laser yeepleyiti zentsimbi.
