1. Ukusika isantya
Abathengi abaninzi ekuboniseni umatshini wokusika i-laser baya kubuza ukuba umatshini we-laser unokusika ngokukhawuleza kangakanani. Enyanisweni, umatshini wokusika i-laser sisixhobo esisebenza kakuhle kakhulu, kwaye isantya sokusika ngokwemvelo sigxininise kubathengi. Kodwa isantya esikhawulezayo sokusika asichazi umgangatho wokusika i-laser.
Ngokukhawuleza kakhulu tyena usika isantya
a. Ayikwazi ukunqumla imathiriyeli
b. Umphezulu wokusika ubonisa i-oblique grain, kwaye isiqingatha esisezantsi somsebenzi sivelisa amabala anyibilikayo
c. I-rough cutting edge
Ukucotha kakhulu isantya sokusika
a. Ngaphezulu kwemeko yokunyibilika kunye nomphezulu wokusika
b. I-gap yokusika ebanzi kunye nekona ebukhali iyancibilika kwiikona ezijikelezileyo
Ukwenza izixhobo zomatshini wokusika i-laser zidlale ngcono umsebenzi wawo wokusika, musa ukubuza nje ukuba umatshini we-laser unokusika kangakanani, impendulo ihlala ingachanekanga. Ngokuchasene noko, nikezela ngeMimoWork ngengcaciso yemathiriyeli yakho, kwaye siya kukunika impendulo enoxanduva ngakumbi.
2. Indawo ekugxilwe kuyo
Ngenxa yokuba ubuninzi bamandla we-laser bunempembelelo enkulu kwisantya sokusika, ukukhethwa kwe-lens ubude bogxininiso yinto ebalulekileyo. Ubungakanani bendawo yelaser emva kokugxila kwelaser bulingana nobude bojoliso belensi. Emva kokuba i-laser beam igxininiswe yi-lens kunye nobude obufutshane obugxilwe, ubungakanani bendawo ye-laser buncinci kakhulu kwaye ubuninzi bamandla kwindawo ekugxilwe kuyo buphezulu kakhulu, enenzuzo ekusikeni izinto eziphathekayo. Kodwa ukungonakali kwayo kukuba ngobunzulu obufutshane bokujolisa, kuphela isibonelelo esincinci sohlengahlengiso lobunzima bezinto eziphathekayo. Ngokubanzi, i-lens egxininisekile enobude obufutshane obugxininisekile ifaneleke ngakumbi kwi-high-speed cut cut material ebhityileyo. Kwaye i-lens ekugxilwe kuyo enobude bojoliso obude inobunzulu bojoliso olubanzi, okoko nje inamandla okwaneleyo oxinaniso, ifaneleka ngakumbi ukusika izinto zokusebenza ezishinyeneyo ezinje ngogwebu, i-acrylic, kunye nomthi.
Emva kokugqiba ukuba yeyiphi i-lens yobude be-focal enokusetyenziswa, indawo ehambelanayo yendawo ekugxilwe kuyo kwindawo yokusebenza ibaluleke kakhulu ukuqinisekisa umgangatho wokusika. Ngenxa yobuninzi bamandla obuphezulu kwindawo ekugxilwe kuyo, kwiimeko ezininzi, indawo ekugxilwe kuyo ingaphantsi okanye kancinane kumphezulu wesixhobo sokusebenza xa usikwa. Kuyo yonke inkqubo yokusika, yimeko ebalulekileyo yokuqinisekisa ukuba indawo ehambelanayo yokugxila kunye ne-workpiece ihlala rhoqo ukufumana umgangatho wokusika ozinzile.
3. Inkqubo yokuVuthela umoya kunye neGesi eNcedisayo
Ngokuqhelekileyo, ukusika kwe-laser yezinto kufuna ukusetyenziswa kwegesi encedisayo, ngokukodwa ehambelana nohlobo kunye noxinzelelo lwegesi encedisayo. Ngokuqhelekileyo, igesi encedisayo ikhutshwe i-coaxially kunye ne-laser beam ukukhusela i-lens ekungcoleni kunye nokuvuthela i-slag ezantsi kwendawo yokusika. Kwizinto ezingezizo zetsimbi kunye nezinye izinto zetsimbi, umoya oxinyiweyo okanye igesi ye-inert isetyenziselwa ukususa izinto ezincibilikisiweyo kunye ne-evaporated, ngelixa zivimbela ukutshisa okugqithiseleyo kwindawo yokusika.
Ngaphantsi kwesiseko sokuqinisekisa igesi encedisayo, uxinzelelo lwegesi luyinto ebaluleke kakhulu. Xa usika izinto ezincinci ngesantya esiphezulu, uxinzelelo lwegesi oluphezulu luyafuneka ukukhusela i-slag ukuba ibambelele ngasemva kwe-cut (i-slag eshushu iya kulimaza i-cut cut xa ibetha i-workpiece). Xa ubukhulu bezinto eziphathekayo bukhula okanye isantya sokusika sicotha, uxinzelelo lwegesi kufuneka luncitshiswe ngokufanelekileyo.
4. Inqanaba lokuJonga
Ubude belaser ye-CO2 yi-10.6 μm elungele ukuba izinto ezingezizo ezentsimbi zifunxe. Kodwa i-laser ye-CO2 ayifanelekanga ukusika isinyithi, ngakumbi izinto zetsimbi ezinokubonakala okuphezulu njengegolide, isilivere, ubhedu kunye nentsimbi ye-aluminium, njl.
Izinga lokufunxa kwezinto kwi-beam lidlala indima ebalulekileyo kwinqanaba lokuqala lokufudumeza, kodwa emva kokuba umngxuma wokusika uqulunqwe ngaphakathi kwendawo yokusebenza, umphumo omnyama womngxuma wenza izinga lokufunxa kwempahla kwi-beam ivale. ukuya kwi-100%.
Ubume bezinto eziphathekayo buchaphazela ngokuthe ngqo ukufunxwa kwe-beam, ngokukodwa uburhabaxa bomphezulu, kunye nomgangatho we-oxide ongaphezulu uya kubangela utshintsho olucacileyo kwisantya sokufunxa. Kwinkqubo yokusika i-laser, ngamanye amaxesha ukusika kwezinto eziphathekayo kunokuphuculwa ngempembelelo yemeko yendawo yezinto eziphathekayo kwizinga lokungena kwe-beam.
5. Laser Head Nozzle
Ukuba umlomo wombhobho awukhethwanga kakuhle okanye awugcinwanga kakuhle, kulula ukubangela ungcoliseko okanye umonakalo, okanye ngenxa yokungqubana okubi komlomo wombhobho okanye ukuvaleka kwendawo okubangelwa kukutshiza kwentsimbi eshushu, imisinga yeedyi iya kwenziwa kumbhobho, nto leyo eya kubangela ukuba kube nokwenzeka kakhulu. ukusebenza kokusika okubi. Ngamanye amaxesha, umlomo we-nozzle awuhambelani nomqadi ogxininisekileyo, okwenza umqadi ukucheba umphetho we-nozzle, oya kuchaphazela umgangatho wokusika umgca, ukwandisa ububanzi bokuqhawula kwaye wenze ukunqunyulwa kobukhulu bokusika.
Kwimibhobho, imiba emibini kufuneka ihlawulwe ingqalelo ekhethekileyo
a. Impembelelo yobubanzi bombhobho.
b. Impembelelo yomgama phakathi kombhobho kunye nomphezulu womsebenzi.
6. Indlela yokubona
Umqadi wokuqala okhutshwe yi-laser usasazwa (kubandakanya ukubonakalisa kunye nokuhanjiswa) ngenkqubo yangaphandle ye-optical path system, kwaye ikhanyise ngokuchanekileyo umphezulu we-workpiece kunye nokuxinana kwamandla aphezulu kakhulu.
Izinto ezibonakalayo zenkqubo yangaphandle ye-optical path kufuneka zihlolwe rhoqo kwaye zilungiswe ngexesha ukuze kuqinisekiswe ukuba xa itotshi yokusika isebenza ngaphezu kwendawo yokusebenza, i-beam yokukhanya idluliselwa ngokuchanekileyo kumbindi we-lens kwaye igxininiswe kwindawo encinci yokusika. i-workpiece enomgangatho ophezulu. Emva kokuba isikhundla se-optical element sitshintshile okanye singcolisekile, umgangatho wokusika uya kuchaphazeleka, kwaye ukusika akunakwenziwa.
I-lens yangaphandle yendlela ye-optical ingcoliswa yizinto ezingcolileyo kwi-airflow kwaye iboshwe ngokutshiza iincinci kwindawo yokusika, okanye i-lens ayipholi ngokwaneleyo, eya kubangela ukuba i-lens igqithise kwaye ichaphazele ukuhanjiswa kwamandla e-beam. Ibangela ukungqubana kwendlela yokubona ukukhukuliseka kwaye ikhokelela kwiziphumo ezibi. I-lens overheating nayo iya kuvelisa ukugqwetheka okugxile kwaye ibeke emngciphekweni lens ngokwayo.
