Uyilo lwe-laser welding fixture yahlula imveliso ethembekileyo kwimisebenzi ebiza kakhulu. Siye sabona abathengi bechitha iiveki belungisa i-weld splatter, ukungahambi kakuhle, okanye ukugqwetheka kwenxalenye-kuphela ukulandelela unobangela wokubuyela kwindawo engaphantsi kobunjineli. Ukuchaneka ayongezwa kwi-post-processing; Itshixiwe ngaphakathi *phambi kokuba* kutshiswe imililo yelaser. E-Botou Haijun Metal Products Co., Ltd., sakha izixhobo zokuwelda i-laser kungekhona njengabagcini nje, kodwa njengabafaki nxaxheba abasebenzayo ukuphindaphinda, ulawulo lwe-thermal, kunye nokuthembeka kwejometri.
Kutheni izilungiso ezisemgangathweni zisilela phantsi kweemeko zeLaser
Amandla okubamba oomatshini kuphela akuqinisekisi uzinzo ngexesha le-1–10 kW sesichengeni selaser. Izahlulo zokwandiswa kwe-thermal phakathi kwezinto ezisisiseko kunye ne-workpiece inokutshintsha inxalenye ye-0.08 mm ngaphakathi kwe-3 imizuzwana-ngokwaneleyo ukuvula i-gap ye-0.2 mm kwi-weld joint. Silinganise oku ngokuphindaphindiweyo sisebenzisa i-thermocouples edibeneyo kunye ne-high-speed CMM yokulandelela kwiindibano zensimbi ezingenasici. Uninzi lwezixhobo ezingaphandle kweshelufu zisebenzisa i-6061-T6 i-aluminiyam yokukhanya-kodwa i-coefficient yayo yokwandiswa kwe-thermal (23.6 µm/m·°C) iphantse yaphinda kabini loo 304 stainless (17.3 µm/m·°C). Oku kungafaniyo kubangela ukuhamba kancinci, ukugxilwa komqadi okungahambelaniyo, kunye ne-porosity.
Ukulungiswa kwakhona kuyasilela xa kungahoywa imiqobo ye-laser-specific: ukufikelela kwi-line-of-sight ye-collimated optics, ukukhutshwa kwe-nozzle yokucoca ukuhamba kwegesi, kunye nonyango lwangaphandle olungabonisiyo. I-pin yokufumana indawo ekhazimlisiweyo ye-316L inokukhangela i-premium-kodwa ibonisa i-65% ye-1070 nm ye-beam yamandla ebuyela kwi-optics. Sitshintshele kwi-matte-finish Inconel 718 izikhonkwane emva kokutshintshwa kweelensi ezimbini kwiveki enye.
ImiGaqo emine yoYilo olungaThengiswayo esiyisebenzisayo
Zonke izixhobo zokuwelda ngelaser esizizisayo zilandela le migaqo iqinisekisiweyo ebaleni:
I-Thermal Decouupling: Iziseko zokulungisa zisebenzisa izinto eziphantsi ze-conductivity ezifana ne-G10 fiberglass okanye i-ceramic-filled PEEK apho ukuhanjiswa kobushushu ngokuthe ngqo kufuneka kuncitshiswe. Iindawo ezibalulekileyo zikhwela kwiipleyiti ezincinci zentsimbi ezingenasici kunye neziqhekeza ze-thermal. UkuQhwatha okunamandla: I-actuator ye-pneumatic okanye i-servo-electric ifaka i-15-25 N / mm² i-clamping pressure-elinganiswa ngexesha langempela-kungekhona ukusetwa kwangaphambili kwamandla entwasahlobo. I-over-clamping ikhubaza izibiyeli zegeyiji encinci; ukunyanzeliswa ngaphantsi kuvumela i-weld ripple eshukumayo. Isingqinisiso soMphezulu woMphezulu: Yonke imiphezulu yedatum iphantsi kweRa ≤ 0.4 µm kwaye ingqinwe nge-optical flat interferometry. Siyayikhaba nayiphi na indawo ene->0.005 mm iyonke yokufundwa kwesalathisi kwi-100 mm—kuba impazamo ye-0.003 mm kwindawo iba yi-0.012 mm kumthungo we-weld we-400 mm. Uhlengahlengiso lweModyuli: Azikho izikhonkwane ezidityanisiweyo. Indawo nganye isebenzisa i-M4–M8 efakelwayo enemisonto enezikhonkwane zentsimbi eqinisiweyo (HRC 60–62), evumela ukuphinda kusetyenziswe ngokupheleleyo ngaphantsi kwemizuzu engama-90 ngaphandle kokulungiswa kwakhona. Unokukhetha nini iSiko kunye neModyuli yeLaser Welding Fixtures
Ezinye iinjineli zicinga ukuba iikiti zemodyuli zonga ixesha. Kodwa siye salandelela iiprojekthi ezili-17 apho iinkqubo “zokulungela ngokukhawuleza” zifuna imijikelo emithathu yeshimming, iiyure ezintlanu zokuhlengahlengiswa kwendlela yelaser, kunye nokuhla kwamandla e-weld okokugqibela nge-12–18%. Imodyuli isebenza kuphela xa inxalenye yejometri ihlala ifana ≥10 ukwahluka-kwaye nalapho, i-thermal drift iqokelelana ngokukhawuleza kunoyilo olwakhiwe ngenjongo.
Uphuhliso lwesiko lwelaser welding luhlawula ngaphantsi kwe 420 iiyure zemveliso kumalungu ane ≥3 imithungo ye weld okanye ukunyamezela kuqina kune ±0.1 mm. Ixesha lethu eliqhelekileyo lokuhamba? Iintsuku ze-12 zokusebenza ukusuka kumzobo ovunyiweyo we-GD & T ukuya kwingxelo yokuhlola inqaku lokuqala-kubandakanywa nokuqinisekiswa kweCMM yazo zonke iimpawu zedatum ngokuchasene ne-ISO 1101.
Asicaphuli izilungiso zodwa. Isicelo ngasinye sixhokonxa uphononongo lwe-DFM: Ngaba ijoyinti iyafikeleleka nge-15° ubuncinane bokufikelela kwi-engile? Ngaba ukuqina kwenxalenye kukuxhasa ukugoba ngaphandle kokubuyiswa kwe-elastic? Ngaba iindawo ze-weld seam azinazo iipokotho zerhasi ezivalelekileyo? Sifaka imiba phambi kokusika isinyithi-kuba ukulungisa kamva kubiza i-7 × ngaphezulu.
Iimetriki zeNtsebenzo yokwenyani yeHlabathi onokuthi uyiqinisekise
Ukulungiswa kwethu kuhlala kuzisa iziphumo ezinokulinganiswa-hayi amabango okuthengisa:
Isikhundla se-Weld siphindaphindeka: ±0.03 mm ngaphezu kwemijikelo eyi-1,000 (ingqinwe ngelaser tracker) Utshintsho-kuya-kulungiso olutshintshanayo: ≤0.05 mm ubukhulu bokutenxa kwiiyunithi ezi-5 ezakhelwe kushicilelo olufanayo Ixesha eliphakathi phakathi kohlengahlengiso: I-14,200 welds (ngokusekelwe kwidatha yangaphakathi ye-2023 kwiiprogram ze-47 ze-bracket zemoto) Ukugcinwa kokugqiba umphezulu: Ra ≤ 0.6 µm kwiindawo ezibalulekileyo emva kweminyaka emi-2 yokusetyenziswa kwemihla ngemihla Zonke iinqanawa zokulungiswa kwenqanawa ezinezatifikethi zolungelelwaniso olulandelekayo ukuya kwi-NIM yaseTshayina, kubandakanywa nolwandiso lwe-thermal coefficients ngokwendawo yemathiriyeli kunye ne-clamping force imaphu eveliswe kuvavanyo lwe-strain-gauge.
Ukusebenza kwe-laser welding ayiyothiyori-ilinganiswa ngee-microns, millisecond, kunye namazinga esivuno. I-Botou Haijun Metal Products Co., Ltd. yakha izixhobo ezibambe inyaniso xa i-laser ibetha, kungekhona nje xa inxalenye ihleli. Ukuba iprojekthi yakho elandelayo ifuna laser welding fixture ukuthembeka-kungekhona nje ukubamba amandla-qala ngenjongo yobunjineli, kungekhona amanani ekhathalogu. Ukuchaneka kuqala apho inxalenye idibana ne-base plate.
