Mapangidwe a laser kuwotcherera amalekanitsa kupanga kodalirika ndi kukonzanso kokwera mtengo. Tawona makasitomala amatha milungu ingapo akuchotsa ma weld splatter, kusalinganika molakwika, kapena kupotoza mbali zina - kungoyang'ana zomwe zidayambitsa kubwereranso kuzomwe sizinapangidwe bwino. Kulondola sikuwonjezedwa pakukonza pambuyo; yatsekeredwa mkati * pamaso* pamoto wa laser. Ku Botou Haijun Metal Products Co., Ltd., timapanga zopangira zowotcherera laser osati zongogwira, koma monga othandizira pakubwereza, kasamalidwe ka matenthedwe, ndi kukhulupirika kwa geometric.
Chifukwa chiyani Zosintha Zokhazikika Zimalephera Pansi pa Mikhalidwe ya Laser
Mphamvu yokhomerera pamakina pawokha sikutsimikizira kukhazikika pakuwonetsa 1-10 kW laser. Kusiyana kwa kukula kwa kutentha pakati pa zinthu zoyambira ndi zogwirira ntchito kumatha kusuntha gawo ndi 0.08 mm mkati mwa masekondi atatu - zokwanira kutsegula kusiyana kwa 0.2 mm pa cholumikizira chowotcherera. Tinayesa izi mobwerezabwereza pogwiritsa ntchito ma thermocouples ophatikizidwa ndi kutsata kothamanga kwa CMM pamisonkhano yazitsulo zosapanga dzimbiri. Zosintha zambiri zapashelufu zimagwiritsa ntchito aluminiyamu ya 6061-T6 kuti ikhale yopepuka, koma coefficient of thermal expansion (23.6 µm/m·°C) ndi pafupifupi kuwirikiza kawiri kuposa 304 zosapanga dzimbiri (17.3 µm/m·°C). Kusagwirizana kumeneku kumapangitsa kuyenda kwa ma micro-, kusagwirizana kwa mtengo, ndi porosity.
Zokonza zimalepheranso akamanyalanyaza zopinga zamtundu wa laser: mwayi wowonekera kwa ma collimated optics, chilolezo chotsuka mpweya wa nozzle, komanso mankhwala osawunikira. Pini yopukutidwa ya 316L yosapanga dzimbiri imatha kuwoneka ngati yofunika kwambiri, koma imawonetsa 65% ya mphamvu ya 1070 nm yobwerera ku optics. Tidasinthira ku matte-finish Inconel 718 pini titasintha ma lens awiri sabata imodzi.
Mfundo Zinayi Zosakambirana Zomwe Timagwiritsira Ntchito
Chilichonse chowotcherera cha laser chomwe timapereka chimatsatira malamulo ovomerezeka awa:
Thermal Decoupling: Zikhazikiko zimagwiritsa ntchito zida zotsika ngati G10 fiberglass kapena PEEK yodzaza ndi ceramic pomwe kutentha kwachindunji kuyenera kuchepetsedwa. Malo ovuta amakwera pazipinda zazing'ono zazitsulo zosapanga dzimbiri zokhala ndi zopuma zotentha. Dynamic Clamping: Ma actuators a pneumatic kapena servo-electric amagwiritsa ntchito 15–25 N/mm² clamping pressure—yoyezedwa mu nthawi yeniyeni—osati mphamvu ya masika yoikidwiratu. Kumangirira mopitirira muyeso kumapindika m'mabulaketi ang'onoang'ono; pansi-clamping imalola kugwedezeka kwa weld ripple. Reference Surface Integrity: Malo onse a datum ali pansi mpaka Ra ≤ 0.4 µm ndipo amatsimikiziridwa ndi optical flat interferometry. Timakana malo aliwonse ndi> 0.005 mm chiwerengero chonse chowerengera pa 100 mm-chifukwa cholakwika cha 0.003 mm pa malo opezekapo chimakhala 0.012 mm pa 400 mm weld seam. Modular Reconfigurability: Palibe zikhomo zowotcherera. Wopeza aliyense amagwiritsa ntchito zoyika za M4–M8 zokhala ndi mapini olimba achitsulo (HRC 60–62), kulola kukonzanso kwathunthu mkati mwa mphindi 90 popanda kukonzanso. Nthawi Yoyenera Kusankha Mwambo vs. Modular Laser Welding Fixtures
Akatswiri ena amaganiza kuti zida za modular zimapulumutsa nthawi. Koma tatsata mapulojekiti 17 pomwe makina "okwanira mwachangu" amafunikira mizere itatu yonyezimira, maola asanu akukonzanso njira ya laser, ndi kutsika kwamphamvu komaliza kwa 12-18%. Modular imagwira ntchito pokhapokha gawo la geometry likhala lofanana pamitundu ≥10 - ndipo ngakhale pamenepo, kusuntha kwamafuta kumachulukana mwachangu kuposa ndi mapangidwe opangidwa ndi cholinga.
Kukula kwa zida zowotcherera za laser kumabwezera m'maola osakwana 420 opangira magawo omwe ali ndi ≥3 ma weld seams kapena zololera zolimba kuposa ± 0.1 mm. Nthawi yathu yeniyeni yotsogolera? Masiku 12 ogwira ntchito kuchokera ku zojambula zovomerezeka za GD&T kupita ku lipoti loyendera nkhani yoyamba-kuphatikiza kutsimikizika kwa CMM kwazinthu zonse zama data motsutsana ndi ISO 1101.
Sitinatchule zosintha paokha. Pempho lililonse limayambitsa kuwunikanso kwa DFM: Kodi cholumikiziracho chikupezeka pa 15° wocheperako? Kodi kuuma kwa gawolo kumathandizira kukanikiza popanda kuchira? Kodi malo opangira ma weld seam alibe matumba amafuta otsekeka? Timayika nkhani tisanadule zitsulo - chifukwa kukonza pambuyo pake kumawononga 7 × zambiri.
Ma Metrics Ogwira Ntchito Padziko Lonse Mutha Kutsimikizira
Zosintha zathu nthawi zonse zimapereka zotsatira zoyezeka - osati zotsatsa:
Weld udindo kubwereza: ± 0.03 mm pa 1,000 mizunguliro (kutsimikiziridwa kudzera laser tracker) Kusinthana-ku-ka-sinthidwe: ≤0.05 mm kupatuka kwakukulu pamayunitsi 5 opangidwa kusindikiza komweko Pakalipano pakati pa zosintha: 14,200 welds (kutengera data yamkati ya 2023 pamapulogalamu 47 amabulaketi amagalimoto) Kusungidwa kwapamwamba: Ra ≤ 0.6 µm pa malo ovuta pambuyo pa zaka 2 zogwiritsidwa ntchito tsiku ndi tsiku Zosintha zonse zimatumizidwa ndi ziphaso zoyeserera ku NIM China, kuphatikiza ma coefficients owonjezera amafuta pagawo lililonse lazinthu ndi mamapu amphamvu oponderezedwa opangidwa ndi kuyesa kwa strain-gauge.
Kuchita kwa laser kuwotcherera sikongoyerekeza - kumayesedwa mu ma microns, ma milliseconds, ndi kuchuluka kwa zokolola. Botou Haijun Metal Products Co., Ltd. imamanga zida zomwe zimakhala zoona laser ikagunda, osati gawo likakhala chete. Ngati polojekiti yanu yotsatira ikufuna chipangizo cha laser kuwotcherera kudalirika—osati kungokhala ndi mphamvu—yambani ndi cholinga cha uinjiniya, osati manambala a m’ndandanda. Kulondola kumayambira pomwe gawolo limakumana ndi mbale yoyambira.
