Ekusetshenzisweni Kwesikhunta, Izimpawu, Izesekeli Zezingxenyekazi Zekhompyutha, Amabhodi Wokukhangisa, amapuleti elayisensi Yezimoto neminye imikhiqizo, izinqubo zokugqwala ezivamile ngeke zibangele ukungcoliswa kwemvelo kuphela, kodwa futhi nokusebenza kahle okuphansi. Izinhlelo zokusebenza zendabuko ezifana nomshini, izinsalela zensimbi nezipholile nazo zingadala ukungcoliswa kwemvelo. Nakuba ukusebenza kahle sekuthuthukisiwe, ukunemba akuphakeme, futhi ama-engeli abukhali awakwazi ukuqoshwa. Uma kuqhathaniswa nezindlela zokuqopha ezijulile zensimbi, i-laser metal deep carving inezinzuzo zokungangcoli, ukunemba okuphezulu, kanye nokuqukethwe okuqoshweyo okuguquguqukayo, okungahlangabezana nezidingo zezinqubo eziyinkimbinkimbi zokubaza.
Izinto ezivamile zokuqopha okujulile kwensimbi zihlanganisa i-carbon steel, insimbi engagqwali, i-aluminium, ithusi, izinsimbi eziyigugu, njll. Onjiniyela benza ucwaningo olusezingeni eliphezulu olujulile lokuqopha ipharamitha yezinto ezihlukene zensimbi.
Ukuhlaziywa kwecala langempela:
Imishini yokuhlola yesikhulumi i-Carmanhaas 3D Galvo Head eneLens (F=163/210) yenza ukuhlolwa okujulile kokuqopha. Usayizi wokuqopha ngu-10 mm×10 mm. Setha amapharamitha okuqala okuqoshwa, njengoba kukhonjisiwe kuThebula 1. Shintsha imingcele yenqubo njengenani le-defocus, ububanzi be-pulse, isivinini, isikhawu sokugcwalisa, njll., sebenzisa umhloli oqoshiwe ojulile ukuze ulinganise ukujula, futhi uthole amapharamitha wenqubo. ngomphumela omuhle kakhulu wokubaza.
Ithebula 1 Imingcele yokuqala yokuqoshwa okujulile
Ngethebula lepharamitha yenqubo, singabona ukuthi kunemingcele eminingi enomthelela kumphumela wokugcina wokuqopha ojulile. Sisebenzisa indlela yokulawula eguquguqukayo ukuze sithole inqubo yomthelela wepharamitha yenqubo ngayinye kumphumela, futhi manje sizowamemezela ngamunye ngamunye.
01 Umthelela we-defocus ekujuleni kokubaza
Okokuqala sebenzisa i-Raycus Fiber Laser Source, Amandla:100W, Imodeli: RFL-100M ukuze uqophe amapharamitha okuqala. Yenza isivivinyo sokuqopha ezindaweni ezehlukene zensimbi. Phinda umdwebo izikhathi eziyi-100 ngamasekhondi angama-305. Shintsha i-defocus futhi uhlole umphumela we-defocus kumphumela oqoshiwe wezinto ezahlukene.
Umfanekiso 1 Ukuqhathaniswa komthelela we-defocus ekujuleni kokuqoshwa kwezinto ezibonakalayo
Njengoba kukhonjisiwe kuMfanekiso 1, singathola okulandelayo mayelana nokujula okuphezulu okuhambisana namanani ahlukene okususa ukugxila lapho kusetshenziswa i-RFL-100M ekuqoshweni okujulile ezintweni zensimbi ezahlukene. Kusukela kudatha engenhla, kuphetha ngokuthi ukuqopha okujulile endaweni yensimbi kudinga i-defocus ethile ukuze uthole umphumela omuhle kakhulu wokuqopha. I-defocus yokuqopha i-aluminium nethusi ingu--3 mm, kanti i-defocus yokuqopha insimbi engagqwali ne-carbon steel ingu--2 mm.
02 Umthelela wobubanzi be-pulse ekujuleni okuqoshiwe
Ngokuhlola okungenhla, inani eliphelele le-defocus le-RFL-100M ekuqoshweni okujulile ngezinto ezihlukile liyatholwa. Sebenzisa inani elilungile le-defocus, shintsha ububanzi be-pulse kanye nemvamisa ehambisanayo kumapharamitha okuqala, futhi amanye amapharamitha ahlala engashintshile.
Lokhu kungenxa yokuthi ububanzi be-pulse ngayinye belaser ye-RFL-100M bunobuningi obuhambisanayo obuyisisekelo. Uma i-frequency iphansi kune-frequency eyisisekelo ehambisanayo, amandla okukhiphayo aphansi kunamandla amaphakathi, futhi uma i-frequency iphakeme kune-frequency eyisisekelo ehambisanayo, amandla aphezulu azokwehla. Ukuhlolwa okuqoshiwe kudinga ukusebenzisa ububanzi obukhulu be-pulse kanye nomthamo omkhulu wokuhlola, ngakho-ke imvamisa yokuhlola iyimvamisa eyisisekelo, futhi idatha yokuhlola efanele izochazwa ngokuningiliziwe ekuhlolweni okulandelayo.
Imvamisa eyisisekelo ehambisana nobubanzi be-pulse ngayinye yilezi: 240 ns, 10 kHz, 160 ns, 105 kHz, 130 ns, 119 kHz, 100 ns, 144 kHz, 58 ns, 179 kHz, 40 ns, 245 kHz, 20 ns, 49 kHz, 10 ns,999 kHz.Yenza isivivinyo sokuqopha ngokusebenzisa ishayela elingenhla kanye nemvamisa, umphumela wokuhlola uboniswa kuMfanekiso 2.
Umfanekiso 2 Ukuqhathaniswa komthelela wobubanzi bokushaya kwenhliziyo ekujuleni kombhalo
Kungabonakala eshadini ukuthi lapho i-RFL-100M iqoshwa, njengoba ububanzi be-pulse buncipha, ukujula okuqoshiwe kuncipha ngokufanele. Ukujula okuqoshiwe kwento ngayinye kukhulu kunama-240 ns. Lokhu kubangelwa ikakhulukazi ukwehla kwamandla e-pulse eyodwa ngenxa yokuncipha kobubanzi be-pulse, okubuye kunciphise umonakalo ebusweni bensimbi, okuholela ekujuleni okuqoshiwe kube kuncane futhi kuncane.
03 Umthelela wemvamisa ekujuleni kokuqoshwa
Ngokuhlola okungenhla, inani elingcono kakhulu le-defocus nobubanzi be-pulse ye-RFL-100M lapho kuqoshwa ngezinto ezihlukile kutholwa. Sebenzisa inani elingcono kakhulu le-defocus nobubanzi be-pulse ukuze uhlale ungashintshiwe, shintsha imvamisa, futhi uhlole umthelela wamafrikhwensi ahlukene ekujuleni kombhalo. Imiphumela yokuhlolwa Njengoba kukhonjisiwe kuMfanekiso 3.
Umfanekiso 3 Ukuqhathaniswa kwethonya lemvamisa ekuqoshweni okujulile kwempahla
Kungabonakala eshadini ukuthi lapho i-laser ye-RFL-100M iqopha izinto ezihlukahlukene, njengoba imvamisa ikhula, ukujula kokuqoshwa kwento ngayinye kuncipha ngokufanele. Uma imvamisa ingu-100 kHz, ukujula kombhalo kukhulu, futhi ukujula okuphezulu kokuqoshwa kwe-aluminium emsulwa kungu-2.43. mm, 0.95 mm ngethusi, 0.55 mm ngensimbi engagqwali, kanye no-0.36 mm ngensimbi yensimbi. Phakathi kwazo, i-aluminium izwela kakhulu ekushintsheni kwemvamisa. Uma imvamisa ingu-600 kHz, ukuqoshwa okujulile akukwazi ukwenziwa phezu kwe-aluminium. Nakuba ithusi, insimbi engagqwali kanye nensimbi ye-carbon kungathinteki kangako ukuvama, futhi kubonisa inkambiso yokuncipha kokujula kokuqoshwa okunobuningi obukhulayo.
04 Umthelela wesivinini ekujuleni kokuqoshwa
Umfanekiso 4 Ukuqhathaniswa komphumela wejubane lokubaza ekujuleni kokubaza
Kungabonakala eshadini ukuthi njengoba ijubane lokuqopha landa, ukujula okuqoshiwe kuncipha ngokufanele. Uma isivinini sokuqoshwa singama-500 mm/s, ukujula okuqoshiwe kwento ngayinye kukhulu kakhulu. Ukujula okuqoshiwe kwe-aluminium, ithusi, insimbi engagqwali ne-carbon steel ngokulandelana: 3.4 mm, 3.24 mm, 1.69 mm, 1.31 mm.
05 Umphumela wokugcwalisa isikhala ekujuleni kokuqoshwa
Umfanekiso 5 Umphumela wokugcwalisa ukuminyana ekusebenzeni kahle kokuqopha
Kungabonakala eshadini ukuthi lapho ukugcwala kokugcwalisa kungu-0.01 mm, ukujula okuqoshiwe kwe-aluminium, ithusi, insimbi engagqwali, ne-carbon steel konke okuphezulu, futhi ukujula okuqoshiwe kunciphisa njengoba igebe lokugcwalisa landa; isikhala sokugcwalisa sikhuphuka sisuka ku-0.01 mm Ngenqubo ka-0.1 mm, isikhathi esidingekayo sokuqedela ukuqoshwa kwe-100 sifinyezwa kancane kancane. Uma ibanga lokugcwalisa likhulu kuno-0.04 mm, ububanzi besikhathi sokunciphisa buncishiswa kakhulu.
Ekuphetheni
Ngokusebenzisa lezi zivivinyo ezingenhla, singathola imingcele yenqubo enconyiwe yokuqoshwa okujulile kwezinto zensimbi ezahlukahlukene kusetshenziswa i-RFL-100M:
