Zopangira zowotcherera zimakhala ndi malo enieni - palibe zongoyerekeza, palibe kukonzanso. Kulekerera kumachepera mpaka ± 0.1 mm ndipo nthawi zozungulira zimafuna kubwerezanso kudutsa mayunitsi 500+, ma jigs wamba amalephera. Ndiko kumene Chida cha 3D welding machitidwe amalowa-osati monga zowonjezera, koma monga zowonjezera zowonjezera za cholinga cha wowotchera.
Chifukwa chiyani "3D" Imasintha Zomwe Ma Fixtures Angachite
Chowotcherera cha 3D sichimatanthauzidwa ndi kuchuluka kwa nkhwangwa. Zimatanthauzidwa ndi momwe zimathetsera zovuta zenizeni padziko lapansi: ma angles ophatikizika m'mabulaketi a chassis, ma flanges okhala ndi ma hydraulic manifolds, kapena magulu azinthu zambiri komwe kukulitsa kwamafuta kumasiyanasiyana pakati pa aluminiyamu ndi chitsulo chosapanga dzimbiri. Tawona makasitomala akutaya 12% yamagulu oyamba chifukwa chotengera cholowacho sichinathe kukhala ndi perpendicularity pakati pa khutu lopindika ndi malo okwera a laser. Kukonzekera sikunali zomangira zolimba - zinali mawonekedwe ogwirizana omwe amatseka ma data mu X, Y, * ndi * Z nthawi imodzi.
Kuthekera kowona kwa 3D kumatanthauza zinthu zitatu pochita:
Modular base mbale okhala ndi malo otsetsereka a T ndi malo obwerezabwereza (± 0.01 mm) Osinthana malo-osati mapini ndi maimidwe okha, koma zothandizira zosinthika kutalika, midadada yachisa chaang'ono, ndi manja omangirira osintha mwachangu okhala ndi torque yokhazikika Integrated reference geometry, kotero kuti gawo lililonse limamanga zisa za datum ndege yomweyo, osati motsutsana ndi mbali ina yosagwirizana. Izi sizongoyerekeza. Mu ntchito imodzi ya zida zaulimi, kusintha kuchokera ku zida za 2D kupita ku 3D fixture idadula kupotoza kwa weld ndi 63% ndikuchepetsa nthawi yokonza pambuyo pa kuwotcherera kuchokera pa mphindi 18 mpaka pansi pa masekondi 90 pa subassembly.
Chomwe Chimapangitsa Fimbo Kukwanira—Osati Kungogwira
Opanga ena amawona zosintha ngati ma templates okhazikika. Timawatenga ngati othandizira ma dynamic process. Makinawa amayenera kupulumuka mizunguliro 5,000+ osataya kukhulupirika kwawo komwe kuli. Iyenera kulola mwayi wofikira ma nyali a MIG, mitu yowotcherera ya robotic, ndikuwunika pambuyo pa weld-popanda kusokoneza. Ndipo ikuyenera kukula: mbale yoyambira yomweyi, malo osiyanasiyana, pamayendedwe a mayunitsi 15 ndi magulu opanga 3,000.
Tapeza zinthu zitatu zomwe sizingakambirane panthawi yotumiza:
Kukhazikika kwakuthupi: Palibe zitsulo zotayira zomwe zimapindika pambuyo pa njinga yamoto yobwerezabwereza. Timagwiritsa ntchito zitsulo zochepetsera nkhawa za 42CrMo4 alloy kapena anodized 7075-T6 aluminiyamu-yoyesedwa kuti isasunthike pa 80 ° C kupitilira maola 72. Kusagwirizana kwamphamvu ya clamp: Zingwe zodzaza ndi masika zimataya mphamvu; pneumatic amafuna mizere ya mpweya. Muyezo wathu umagwiritsa ntchito zingwe zomangira zitsulo zolimba zokhala ndi loko yabwino - yotsimikizika pa 12 kN yogwira mphamvu, yobwerezedwa mkati mwa ± 3% Serviceability: Malo amavala. Ma pin amawombedwa. Chifukwa chake chowotcherera chilichonse cha 3D chimaphatikizapo zoyikapo zolimba zosinthika - osati zida zamakina - ndi BOM yathunthu yokhala ndi nthawi zotsogola zosakwana maola 72. Wogulitsa magalimoto wina waku North America Tier-1 anakana lingaliro lathu loyambirira chifukwa chopanga maloboti awo amafunikira ma TCP enieni. Tidaphatikizira zosinthazo mwachindunji mumtundu wa CAD-operekedwa ngati mafayilo a STEP okhala ndi ma callout a GD&T ogwirizana ndi makina awo owongolera maloboti. Adayendetsa kutsimikizika koyamba m'maola 4.2.
Momwe Kulondola Kumayambira Pamaso Pa Weld Yoyamba
Chowotcherera cha 3D sichilipira mapangidwe olakwika - chimawulula. Tawunikanso zithunzi zopitilira 200 zamakasitomala pomwe ma weld amawoloka mizere yokhotakhota, zomwe zimapangitsa kuti pakhale ming'alu m'malo opsinjika kwambiri. Kapena kumene milu ya kulolerana inapangitsa kuti msonkhano womaliza ukhale wosatheka—ngakhale kuti mbali iliyonse inadutsa kuyendera limodzi.
Ichi ndichifukwa chake chithandizo chathu cha uinjiniya chimayamba * tisanapange * zopanga:
Kuyika kwa seam yoyendetsedwa ndi DFM: Timatsanzira kagawidwe ka kutentha ndikupereka malingaliro osunthika msoko kuti tichepetse kusokonekera-zolembedwa ndi mamapu amitundu yotentha. Ndemanga ya njira ya Datum: Kodi datum yanu yoyamba ikugwirizana ndi malo opangira makina? Ndi mizere yolekanitsa? Ndi malo oyendera a CMM otsika? Timapanga mapu onse atatu Kusintha-ku-kachitidwe handoff: Sitingopereka zida zokha, koma ma weld parameter omwe amatsimikiziridwa pa makulidwe azinthu zofanana, mitundu yama waya, ndi ma geometri olowa. Palibe zida za "mulingo umodzi wokwanira-zonse". Aliyense Chida cha 3D welding timapanga zimayamba ndi zofunikira za gawo lanu-osati manambala athu amndandanda.
Zotsatira Zenizeni, Osati Benchmarks
Ku Botou Haijun Metal Products Co., Ltd., timayesa zosintha zomwe zili ndi katundu, osati kulemera kwa static, koma kutengera kamvekedwe kapangidwe. Chitsulo chovotera 3 mm mild steel chiyenera kukhala chowona kudzera m'mizere yotsatizana 100 pa kutentha kwa 120 ° C, ndi 3-sekondi imodzi yolumikizira, ndi 15-sekondi zowotcherera - zonsezo zimalowetsedwa kudzera m'ma geji ophatikizika ndi matenthedwe.
Makasitomala athu amafotokoza zotsatira zosasinthika:
Kuchepetsa 92% pakusintha koyenera kwa nkhani yoyamba Kupanikizika kwa nthawi ya weld cycle kwa 18-27%, kutsimikiziridwa ndi maphunziro oyenda nthawi Mlingo wa scrap watsika kuchokera pa 4.7% mpaka 0.3% pamisonkhano yovuta yokhala ndi ≥7 zolumikizira zowotcherera Sitigulitsa zosintha. Timapereka kubwereza-kuyesedwa mu ma microns, kutsatiridwa mumphindi, kutsimikiziridwa molembedwa. Chifukwa pamene katundu wanu akuyenda, kukweza, kapena kunyamula katundu, weld si olowa chabe. Ndi maziko.
