Intsimbi yekhabhoni
Ngenxa yokuba i-carbon steel iqulethe ikhabhoni, ayibonakalisi ukukhanya ngamandla kwaye ifunxa kakuhle imiqadi yokukhanya.Intsimbi yeCarbon ifanelekile ukusika i-laser kuzo zonke izinto zetsimbi.Ke ngoko, oomatshini bokusika i-carbon steel laser banendawo engenakushukunyiswa kwi-carbon steel processing.
Ukusetyenziswa kwekhabhoni yensimbi kuya kuba kuninzi ngakumbi.Yangokuoomatshini bokusika laserinokunqumla ubukhulu obukhulu beepleyiti zensimbi zekhabhoni ukuya kwi-20MM.I-slit yokusika i-carbon steel usebenzisa i-oxidative melting kunye nendlela yokusika inokulawulwa kububanzi obanelisayo.Ukuya malunga ne-0.1MM.
Yenziwe ngentsimbi eshayinayo
I-Laser yokusika insimbi engenasici isebenzisa amandla akhutshiweyo xa i-laser beam ifakwe kwi-irradiated kumphezulu wepleyiti yensimbi ukuze inyibilike kwaye ikhuphe insimbi engenasici.Kwishishini lokuvelisa elisebenzisa ishidi lensimbi engenasici njengeyona nto iphambili, ukusika i-laser yensimbi engenasici yindlela ekhawulezayo nesebenzayo yokucubungula.Iiparamitha zenkqubo ebalulekileyo echaphazela umgangatho wokusika wensimbi engenasici kukusika isantya, amandla e-laser, kunye noxinzelelo lomoya.
Xa kuthelekiswa nentsimbi ephantsi yekhabhoni, ukusika insimbi engenasici kufuna amandla aphezulu e-laser kunye noxinzelelo lwe-oxygen.Nangona ukusika kwensimbi engenasici kufezekisa umphumo owanelisayo wokusika, kunzima ukufumana i-slag-free cut seams ngokupheleleyo.Uxinzelelo oluphezulu lwe-nitrogen kunye ne-laser beam ifakwe i-coaxially ukuvuthela isinyithi esityhidiweyo ukuze kungabikho i-oxide eyenziwa kwindawo yokusika.Le yindlela efanelekileyo, kodwa ibiza kakhulu kunendlela yokusika i-oxygen yendabuko.Enye indlela yokutshintsha initrogen esulungekileyo kukusebenzisa umoya ocinezelweyo wezityalo ohluziweyo, oquka i-78% yenitrogen.
Xa i-laser yokusika isibuko sensimbi engenasici, ukwenzela ukukhusela ibhodi ekutshiseni okunzulu, ifilimu ye-laser iyadingeka!
I-aluminium kunye ne-alloy
Nangona umatshini wokusika we-laser ungasetyenziswa ngokubanzi ekuqhutyweni kwezinto ezahlukeneyo zetsimbi kunye nezingezo zetsimbi.Nangona kunjalo, ezinye izinto, ezifana nobhedu, i-aluminium, kunye ne-alloys yazo, zenza kube nzima ukusika i-laser ngenxa yeempawu zabo (ukubonakala okuphezulu).
Okwangoku, i-aluminium plate laser cutting, i-fiber lasers kunye ne-YAG lasers zisetyenziswa ngokubanzi.Zombini ezi zixhobo zisebenza kakuhle ekusikeni i-aluminiyam kunye nezinye izinto, njengentsimbi engatyiwayo kunye nentsimbi yekhabhoni, kodwa azinakucutshungulwa ngakumbi.Aluminiyam.Ngokubanzi, ubukhulu obukhulu be-6000W bunokunqunyulwa ukuya kwi-16mm, kwaye i-4500W inokunqunyulwa ukuya kwi-12mm, kodwa ixabiso lokucubungula liphezulu.Igesi encedisayo esetyenziswayo isetyenziselwa ukuvuthela imveliso etyhidiweyo ukusuka kwindawo yokusika, kwaye ngokubanzi umgangatho ongcono wokusika unokufumaneka.Kwezinye ii-alloys ze-aluminium, ingqalelo kufuneka ihlawulwe ekukhuseleni i-micro-cracks ebusweni be-slit.
Ubhedu kunye ne-alloys
Ubhedu olucocekileyo (ubhedu) alunakunqunyulwa nge-laser beam ye-CO2 ngenxa yokukhanya kwayo okuphezulu.I-Brass (i-alloy yobhedu) isebenzisa amandla aphezulu e-laser, kwaye igesi encedisayo isebenzisa umoya okanye i-oxygen, enokuthi inqumle iipleyiti ezincinci.
I-Titanium kunye ne-alloys
Ukusika i-laser ye-titanium alloys edla ngokusetyenziswa kwishishini leenqwelomoya kunomgangatho olungileyo.Nangona kuya kubakho intsalela encangathi encinci ezantsi kwe-slit, kulula ukuyisusa.I-titanium ecocekileyo inokudityaniswa kakuhle kunye namandla ashushu aguqulwe ngumqa we-laser ogxilileyo.Xa igesi encedisayo isebenzisa i-oksijini, ukuphendulwa kweekhemikhali kubukhali kwaye isantya sokusika sikhawuleza.Nangona kunjalo, kulula ukwenza i-oxide layer kwi-cut cut, kwaye ukutshisa ngengozi kunokwenzeka.Ngenxa yokuzinza, kungcono ukusebenzisa umoya njengegesi encedisayo ukuqinisekisa umgangatho wokusika.
Intsimbi ye-alloy
Uninzi lweentsimbi zolwakhiwo lwe-alloy kunye neentsimbi zesixhobo se-alloy zinokusikwa nge-laser ukufumana umgangatho olungileyo wokusika.Kwanakwizinto ezithile eziphezulu zokuqina, nje ukuba iiparitha zenkqubo zilawulwa ngokufanelekileyo, imida yokusika eqondileyo kunye ne-slag-free ingafumaneka.Nangona kunjalo, kwi-tungsten-equkethe i-tungsten-high-speed tool steels kunye ne-hot-mold steels, i-ablation kunye ne-slagging zenzeka ngexesha lokusika kwe-laser.
I-nickel alloy
Kukho iintlobo ezininzi ze-nickel-based alloys.Uninzi lwazo lunokuba phantsi kwe-oxidative fusion cut.
