Iingxaki ezinokwenzeka xa iipleyiti zokusika nge-laser

Kwi-laser cutting, kukho iingxaki ezifana ne-scum ezantsi kwe-workpiece, ukugoba kwisiphelo esisezantsi somphezulu wokusika, ukutshiswa kakhulu kwee-engile zasekunene/iikona ezibukhali, kunye nomphezulu wokusika orhabaxa. Oku kulandelayo kuya kusombulula ngokucwangcisiweyo izizathu kunye nezisombululo zezi ngxaki.

Isishwankathelo sokusombulula iingxaki eziphambili

Ingxaki 1: umhlwa osezantsi kwento yokusebenza (inkunkuma exhonyiweyo)

Uhlalutyo lwesizathu: emva kokuba i-laser inyibilikise izinto, ayikwazi ukuvuthuzwa ukusuka ezantsi kwesithintelo yigesi encedisayo ngexesha elifanelekileyo, ngaloo ndlela ijiya kwaye yenze i-slag exhonyiweyo. Oku ngokuyintloko ngumbandela wokulinganisela amandla kunye negesi.

Isisombululo:

1. Lungiselela iiparameter zegesi:

• Uxinzelelo; Kwintsimbi engagqwaliyo, i-aluminium alloy, njl.njl., xa usebenzisa i-nitrogen njengegesi encedisayo ecocekileyo kakhulu, uxinzelelo kufuneka lube phezulu ngokwaneleyo (umzekelo, i-1.6MPa okanye ngaphezulu) ukuze kufezekiswe ukusika okungena-oxidation kunye nokutshaya i-slag. Xa usebenzisa i-oxygen kwintsimbi yekhabhoni, uxinzelelo kufuneka lube phakathi, phezulu kakhulu kuya kuqinisa impendulo yokwenza i-slag erhabaxa.
• Ubunyulu kunye nohlobo: ukuqinisekisa ukuba ubunyulu begesi (ingakumbi i-nitrogen ifuna ngaphezulu kwama-99.9%), ubunyulu be-oksijini nabo kufuneka bube ngaphezulu kwama-99.5%.

2. Lungisa ukugxila kwemitha:

• Ukuphambuka kwindawo yokugxila yeyona nto ixhaphakileyo. Yenza umlinganiselo wokugxila kwaye uzame ukulungisa indawo yokugxila phezulu nasezantsi. Ngokubanzi, ukunciphisa ukugxila kancinci (ngaphakathi ngaphakathi kwezinto) kunceda ukuphucula umgangatho wokusika osezantsi.

3. Lungisa amandla kunye nesantya

• Isantya esikhawulezayo kakhulu okanye amandla aphantsi kakhulu aya kukhokelela ekunqunyulweni, ukwakheka kwe-slag ethambileyo exhonyiweyo; isantya esicothayo kakhulu okanye amandla aphezulu kakhulu aya kukhokelela ekunyibilikeni kakhulu, ukwakheka kwe-slag exhonyiweyo eqinileyo nebuthathaka. Kubalulekile ukufumana indibaniselwano yesantya samandla esifanelekileyo esihambelana nobukhulu bephepha.

4. Jonga kwaye utshintshe umlomo:

• Ukusetyenziswa kwemilomo eyonakeleyo, egoso okanye engahambelaniyo kunokuphazamisa ukuhamba komoya. Jonga ukuba umngxuma osembindini wemilomo ujikelezile na, uze ukhethe umlomo onobubanzi obufanelekileyo ngokobukhulu bepleyiti (ngesiqhelo ububanzi obukhulu kwipleyiti etyebileyo kunye nobubanzi obuncinci kwipleyiti ebhityileyo).

Ingxaki yesi-2: Sika iipleats ezisezantsi (imivimbo/ukutsha kakhulu)

Uhlalutyo lwesizathu: Le yinto eqhelekileyo yokutsha kakhulu. Ngenxa yokufakwa kobushushu obuninzi, izinto ziyanyibilika kakhulu okanye ziphele ziphele, zenze imivimbo erhabaxa, efana nemibimbi kwisiqingatha esisezantsi secandelo lokusika.

Isisombululo:

• Uhlengahlengiso oluphambili: Ukwandisa isantya sokusika. Isantya sicotha kakhulu sisizathu esiphambili, ukuphucula isantya kunokunciphisa i-laser kwindawo yeyunithi yendima yexesha, ukuze kuthintelwe ukuqokelelana kobushushu.
• Nciphisa amandla elaser. Ukuba isantya asisakwazi ukunyuswa, okanye ukuphakamisa kukhokelela ekunqunyulweni, amandla kufuneka ancitshiswe ngokufanelekileyo ukuze kuncitshiswe ubushushu obupheleleyo.
• Lungisa indawo yokugxila. Zama ukunciphisa indawo yokugxila kancinci ukuze wenze amandla agxile ngakumbi kwaye unciphise indawo echaphazelekileyo bubushushu.
• Jonga kwaye unciphise uxinzelelo lwegesi oluncedisayo. Ingakumbi xa usebenzisa ioksijini ekusikeni intsimbi yekhabhoni, uxinzelelo lweoksijini oluphezulu kakhulu luya kwenza kube nzima ukusabela kweoksijini njengento "yokuphucula ukutsha" kwaye ivelise ubushushu obugqithisileyo. Ukwehlisa uxinzelelo lomoya ngokufanelekileyo kunokuba nemiphumo engalindelekanga.

Ingxaki 3: I-Engile Yasekunene/Ukutshisa Okubukhali

Uhlalutyo lwesizathu: Isantya sentloko yokusika nge-laser sizinzile xa uhamba kumgca othe tye, kodwa xa usika kwi-engile yasekunene okanye kwi-engile ebukhali, kufuneka ihlehlise isantya, ijike, kwaye ikhawuleze kwakhona. Ukuwa kwesantya ekhoneni kubangela ukuba ixesha lokuhlala kwe-laser libe lide, kwaye ubushushu buqokelelana ngokukhawuleza, ngaloo ndlela bususa ikona ebukhali.

Isisombululo:

1. Sebenzisa i-rounded corner transition (eyona ndlela isebenzayo):

• Kwinqanaba loyilo lomzobo, ikona ebukhali itshintshwa ibe yikona encinci ejikelezileyo (ikona engu-R). Kwanefillet encinci enobubanzi obuyi-0.5mm ingenza intloko yokusika itshintshe kakuhle, iphephe utshintsho olukhulu kwisantya, kwaye ithintele ngokufanelekileyo ukutsha kakhulu.

2. Sebenzisa umsebenzi wenkqubo yekona (umsebenzi wekona eqaqambileyo):

• Iinkqubo zokusika i-laser zanamhlanje ziza nomsebenzi "wolawulo lwamandla ekhoneni" okanye "wekona eqaqambileyo". Lo msebenzi unokwenza oku kulandelayo:
• Xa kufunyenwe ikona, amandla elaser ancitshiswa ngokuzenzekelayo.
• Okanye sebenzisa ukusika okuhlukaniswe ngamasebe, cima i-laser ekhoneni okwethutyana, uze unqumle ibe ngamacandelo amabini.
• Nceda ujonge incwadi yemiyalelo yenkqubo yokusebenza yesixhobo sakho ukuze ukwazi ukuyivula nokulungisa olu phawu.

3. Yehlisa isantya sokusika ekhoneni:

• Kwitheyibhile yeparameter yenkqubo, isantya sokusika sekona simiselwe ngokwahlukeneyo ukuze sibe ngaphantsi kunesantya esithe ngqo, kodwa oku kufuneka kusetyenziswe kunye nokunciphisa amandla.

Ingxaki 4: umphezulu wokusika orhabaxa (umgubo othe nkqo)

Uhlalutyo lwesizathu: umphezulu wokusika ubonakala ucacile, kungekhona imivimbo ethe nkqo egudileyo, ngokuqhelekileyo ngenxa yokungazinzi kwamandla okanye ukungafani kweeparameter, okubangela imeko yokunyibilika okungalinganiyo kwezinto.

Isisombululo:

• Qinisekisa ukuba indawo yokugxila ichanekile kwaye izinzile: Le yeyona nto ibalulekileyo ukuze ufumane umphezulu wokusika ogudileyo. Utshintsho oluncinci kwingqwalasela luya kukhokelela kumahluko omkhulu kwimigca enqamlezileyo. Coca kwaye ulinganise ilensi yokugxila ukuqinisekisa ukuba ingqwalasela izinzile.
• Sebenzisa igesi encedisayo ecocekileyo kakhulu: Ukungcola kwigesi kunokuphazamisa ukuhamba kunye nenkqubo yokupholisa yesinyithi esinyibilikisiweyo, nto leyo ebangela iindawo ezirhabaxa.
• Lungiselela isantya sokusika: Isantya esingazinzanga okanye ukuseta okungafanelekanga kuya kubangela ukuba isinyithi esinyibilikisiweyo senze imicu engalinganiyo ngexesha lenkqubo yokupholisa. Fumana isantya esizinzileyo esivelisa iitships eziqhubekayo nezigudileyo.

Jonga uzinzo lwezixhobo:

• Ingaba isiporo esikhokelayo sigudile? Ukungcangcazela kwezixhobo kuya kubonakala ngokuthe ngqo kumphezulu wokusika.
• Ingaba i-nozzle i-coaxial kunye nomqadi? Ukuhamba komoya kwee-axes ezahlukeneyo kunokubangela ukungalingani kunye noburhabaxa becandelo.
• Ngaba iilensi zokukhanya zicocekile okanye zonakele? Iilensi ezingcolileyo zinokusasaza amandla e-laser, nto leyo ebangela ukuba kuqhekeke amanxeba kwaye kubekho iindawo ezirhabaxa.

Uluhlu lokuHlola lweSiseko esiBanzi

Ngaphambi kokuba wenze naluphi na uhlengahlengiso lweparameters, qiniseka ukuba wenza olu hlolo lulandelayo olusisiseko:

1. Ilensi yokukhanya:khangela ukuba ilensi egxile kwi-focus kunye nelensi ekhuselayo zicocekile na, akukho ngcoliseko, akukho mabala amanzi, akukho monakalo.

2. Ukulungelelaniswa kwemilomo:Qinisekisa ukuba umqadi welaser udlula ngokugqibeleleyo usuka embindini wempumlo.

3. Isekethe yegesi negesi:qinisekisa ukuba akukho kuvuza kwisekethe yegesi, kwaye uhlobo lwegesi kunye nobunyulu zichanekile.

4. izinto:ukuqinisekisa ukuba umphezulu wepleyiti ucocekile, akukho maleko we-oxide, ioyile, kunye nezinto ezifanayo.

Isishwankathelo kunye neeNgcebiso

Ukusika nge-laser yinkqubo echanekileyo ene-multi-parameter synergy. Eyona nto ibalulekileyo ekusombululeni ingxaki kukutshintsha i-variable enye ngexesha kunye nokugcina iirekhodi ukuze ufumane unobangela wengxaki.
