Kulo mhlahlandlela, sizohlola konke odinga ukukwazi mayelana ne-laser cutting aluminium. Sizocacisa ukuthi inqubo isebenza kanjani, izinzuzo ezibalulekile, ukuhamba komsebenzi kwesinyathelo nesinyathelo ukusuka kumklamo ukuya engxenyeni eqediwe, kanye nezisetshenziswa ezibalulekile ozidingayo. Sizophinde sihlanganise izinselele zobuchwepheshe nokuthi ungazinqoba kanjani, siqinisekise ukuthi ungafinyelela ukusikeka okuphelele ngaso sonke isikhathi.

Iyini i-Laser Cutting Aluminium futhi Isebenza Kanjani?

Ukusika i-laser kuyinqubo yokushisa engathinteki esebenzisa umsebe wokukhanya ogxile kakhulu ukuze usike izinto ngokunemba okumangalisayo. Emgogodleni wayo, inqubo iwukusebenzisana okuphelele phakathi kwamandla agxilile nokunemba kwemishini.

• I-Core Process:Inqubo iqala lapho ijeneretha ye-laser idala umsebe wokukhanya onamandla, ohlangene. Le nsimbi iqondiswa ngezibuko noma ngentambo ye-fiber optic iye ekhanda lokusika lomshini. Lapho, ilensi igxilisa yonke induku endaweni eyodwa, encane encane endaweni ye-aluminium. Lokhu kuhlangana kwamandla kushisisa insimbi ngokushesha kudlule indawo yayo yokuncibilika (660.3∘C / 1220.5∘F), okubangela ukuthi izinto ezisendleleni yohlaka zincibilike futhi zihwamuke.

• Iqhaza Legesi Yokusiza:Njengoba i-laser incibilikisa i-aluminiyamu, ijethi yokusiza igesi enomfutho ophezulu idutshulwa ngombhobho ofanayo. Nge-aluminium, lena cishe njalo i-nitrogen ehlanzekile kakhulu. Le jethi yegesi inemisebenzi emibili: okokuqala, iphephetha ngamandla insimbi encibilikisiwe iphume emzileni osikiwe (i-kerf), iyivimbele ukuthi ingaqini kabusha futhi ishiye unqenqema oluhlanzekile, olungenawo amanyela. Okwesibili, ipholisa indawo ezungeze ukusika, okunciphisa ukuphazamiseka kokushisa.

• Amapharamitha angukhiye wempumelelo:Ukusikwa kwekhwalithi kuwumphumela wokulinganisa izici ezintathu ezibalulekile:

  • Amandla e-Laser (Watts):Inquma ukuthi angakanani amandla alethwayo. Kudingeka amandla engeziwe ezintweni eziwugqinsi noma isivinini esisheshayo.

  • Isivinini sokusika:Izinga lapho ikhanda elisika lihamba khona. Lokhu kufanele kuhambisane ngokuphelele namandla ukuze kuqinisekiswe ukusika okugcwele, okuhlanzekile ngaphandle kokushisa ngokweqile.

  • Ikhwalithi ye-Beam:Kubhekisela ekutheni i-beam ingagxilwa ngokuqinile. I-beam yekhwalithi ephezulu ibalulekile ekugxiliseni amandla ngokuphumelelayo, okubalulekile ekusikeni okubonakalayo njenge-aluminium.

Izinzuzo Eziyinhloko Ze-Laser Cutting Aluminium

Ukukhetha i-laser cut aluminium kunikeza izinzuzo ezibalulekile kunezindlela ezindala njenge-plasma noma ukusika imishini. Izinzuzo eziyinhloko zingena ezigabeni ezintathu: ikhwalithi, ukusebenza kahle, nokugcinwa kwezinto ezibonakalayo.

• Ukunemba Nekhwalithi:Ukusika kwe-Laser kuchazwa ngokunemba kwayo. Ingakhiqiza izingxenye ezinokubekezelelana okuqinile kakhulu, ngokuvamile phakathi kuka-±0.1 mm (±0.005 amayintshi), okuvumela ukudalwa kwamajiyometri ayinkimbinkimbi futhi ayinkimbinkimbi. Amaphethelo avelayo abushelelezi, abukhali, futhi cishe awanawo ama-burr, okuvamise ukuqeda isidingo sezinyathelo zokuqeda ezidla isikhathi kanye nezindleko ezibizayo ezifana nokususa noma ukwenza isihlabathi.

• Ukusebenza Nesivinini: Ama-Laser cuttersziyashesha futhi zisebenza ngempumelelo. I-kerf encane (ububanzi obunqunyiwe) isho ukuthi izingxenye "zingafakwa" eduze kakhulu eshidini le-aluminium, ukwandisa ukusetshenziswa kwezinto ezibonakalayo futhi kunciphise kakhulu udoti olahliwe. Le nto kanye nokonga isikhathi kwenza inqubo ingabizi kakhulu kukho kokubili ukwenziwa kwe-prototyping kanye nokuqhutshwa kokukhiqiza okukhulu.

• Ukulimala Okuncane Kokushisa:Inzuzo enkulu indawo encane kakhulu Ethinteke Ukushisa (HAZ). Ngenxa yokuthi amandla e-laser agxile kakhulu futhi ahamba ngokushesha, ukushisa akunasikhathi sokusakazeka ezintweni ezizungezile. Lokhu kulondoloza ukuthukuthela nobuqotho besakhiwo se-aluminium kuze kufike onqenqemeni lokusikwa, okubalulekile ezingxenyeni ezisebenza kahle kakhulu. Kuphinde kunciphise ubungozi bokungqubuzana nokuhlanekezela, ikakhulukazi kumashidi amancanyana.

Inqubo yokusika i-Laser: Umhlahlandlela wesinyathelo ngesinyathelo

Ukuguqula ifayela ledijithali libe yingxenye ye-aluminium ebonakalayo kulandela ukuhamba komsebenzi okucacile, okuhlelekile.

1. Ukuklama nokulungiselela:Inqubo iqala ngomklamo wedijithali we-2D odalwe kusofthiwe ye-CAD (njenge-AutoCAD noma i-SolidWorks). Leli fayela lisho izindlela zokusika eziqondile. Kulesi sigaba, i-aluminium alloy efanele (isb, 6061 yamandla, 5052 for formability) kanye nogqinsi kukhethwa ukuze isicelo.

2. Ukusethwa komshini:Umsebenzisi ubeka ishidi elihlanzekile le-aluminium embhedeni womsiki we-laser.
