Zigawo zazikulu, zopyapyala zokhala ndi mipanda ndizosavuta kupindika ndikupunduka panthawi yokonza. M'nkhaniyi, tidzakambirana za kutentha kwa kutentha kwa zigawo zazikulu ndi zowonda kuti tikambirane za mavuto omwe amapangidwa nthawi zonse. Kuphatikiza apo, timaperekanso njira yabwino komanso yankho lokhazikika. Tiyeni tifike kwa izo!
Mlanduwu ndi wa chipolopolo chopangidwa ndi zinthu za AL6061-T6. Nawa miyeso yake yeniyeni.

Chitani ndi Zovuta M'njira Zosiyanasiyana
Pa CNC Machining, izi woonda-mipanda zipolopolo nyumba zambiri kumabweretsa osiyanasiyana mavuto, monga warping ndi mapindikidwe. Kuti tithane ndi mavutowa, timayesetsa kupereka njira za njira za serval. Komabe, palinso zovuta zina panjira iliyonse. Nazi tsatanetsatane.
Njira Yopangira 1
Pochita 1, timayamba ndikukonza mbali yakumbuyo (mbali yamkati) ya chogwirira ntchito ndikugwiritsira ntchito pulasitala kudzaza madera opanda dzenje. Kenako, kulola kuti mbali yakumbuyo ikhale yofotokozera, timagwiritsa ntchito guluu ndi tepi ya mbali ziwiri kukonza mbali yolozerayo kuti tigwiritse ntchito kutsogolo.
Komabe, pali mavuto ena ndi njira imeneyi. Chifukwa cha malo akulu otsekeredwa kumbuyo chakumbuyo, guluu ndi tepi yambali ziwiri sizimatetezedwa mokwanira. Zimatsogolera ku warping pakati pa workpiece ndi kuchotsa zinthu zambiri mu ndondomeko (yotchedwa overcutting). Komanso, kupanda kukhazikika kwa workpiece kumabweretsanso otsika processing dzuwa ndi osauka pamwamba mpeni chitsanzo.
Njira Yopangira 2
Mu process 2, timasintha dongosolo la makina. Timayamba ndi pansi (mbali yomwe kutentha kumatayika) ndikugwiritsira ntchito pulasitala backfilling ya dzenje. Kenako, kulola mbali yakutsogolo ngati cholozera, timagwiritsa ntchito guluu ndi tepi ya mbali ziwiri kukonza mbali yolozera kuti tigwire kumbuyo.
Komabe, vuto la njirayi ndi lofanana ndi njira ya 1, kupatula kuti nkhaniyo imasunthidwa kumbali yakumbuyo (mbali yamkati). Apanso, mbali yakumbuyo ikakhala ndi malo akulu otsekera kumbuyo, kugwiritsa ntchito guluu ndi tepi yokhala ndi mbali ziwiri sizipereka kukhazikika kwakukulu kwa chogwiriracho, zomwe zimapangitsa kuti pakhale nkhondo.
Njira Yopangira 3
Mu ndondomeko ya 3, timaganizira kugwiritsa ntchito ndondomeko ya makina a ndondomeko 1 kapena ndondomeko 2. Kenaka muzitsulo zachiwiri, gwiritsani ntchito mbale yosindikizira kuti mugwire ntchitoyo mwa kukanikiza pansi pamtunda.
Komabe, chifukwa cha dera lalikulu la mankhwala, platen amatha kuphimba dera lozungulira ndipo sakanatha kukonza bwino malo apakati a workpiece.
Kumbali imodzi, izi zimapangitsa kuti malo apakati a workpiece awonekebe kuchokera ku warping ndi mapindikidwe, zomwe zimapangitsa kuti pakhale kupitirira pakati pa mankhwala. Kumbali inayi, njira yopangira izi ipangitsa kuti zipolopolo za CNC zopyapyala zikhale zofooka kwambiri.
Njira Yopangira 4
Pochita 4, timayika mbali yakumbuyo (mbali yamkati) poyamba ndikugwiritsira ntchito vacuum chuck kumangirira ndege yobwerera kumbuyo kuti igwire ntchito yakutsogolo.
Komabe, pankhani ya chigoba chopyapyala chokhala ndi mipanda yopyapyala, pali zopindika ndi zopingasa kumbuyo kwa chogwiriracho zomwe tiyenera kupewa tikamagwiritsa ntchito vacuum suction. Koma izi zidzayambitsa vuto latsopano, madera opewedwa amataya mphamvu zawo zoyamwa, makamaka m'madera anayi a ngodya pa circumference ya mbiri yaikulu.
Pamene madera omwe sanatengedwe akugwirizana ndi mbali yakutsogolo (malo opangidwa ndi makina panthawiyi), chida chodulira chikhoza kuchitika, zomwe zimapangitsa kuti pakhale chida chogwedeza. Choncho, njirayi ikhoza kukhala ndi zotsatira zoipa pa khalidwe la makina ndi kumaliza pamwamba.
Optimized Process Route And Fixture Solution
Kuti tithane ndi mavuto omwe ali pamwambawa, tikupangira njira zokongoletsedwera zotsatirazi ndi zothetsera.
Pre-machining Screw Through-holes
Choyamba, tinakonza njira yopita patsogolo. Ndi yankho latsopanoli, timakonza mbali yakumbuyo (mbali yamkati) poyamba ndikuyika makina obowo m'malo ena omwe pamapeto pake adzatsekeredwa. Cholinga cha izi ndi kupereka njira yabwino yokonza ndi kuika muzotsatira zamakina.
Zungulirani Malo Amene Adzakonzedwa
Kenako, timagwiritsa ntchito ndege zomangika kumbali yakumbuyo (mbali yamkati) ngati njira yopangira makina. Nthawi yomweyo, timatchinjiriza chogwirira ntchito podutsa wonongazo kuchokera munjira yapitayi ndikuyitsekera ku mbale. Kenaka zungulirani malo omwe wonongayo yatsekedwa ngati malo oti apangidwe.
Sequential Machining ndi Platen
Panthawi yokonza makinawo, timayamba timakonza madera ena osati malo oti tizimangirirako. Maderawa akapangidwa, timayika mapulaneti pa malo opangidwa ndi makina (platen iyenera kuphimbidwa ndi guluu kuti tipewe kuphwanyidwa kwa makina opangidwa ndi makina). Kenaka timachotsa zomangira zomwe zimagwiritsidwa ntchito mu sitepe 2 ndikupitiriza kukonza madera oti apangidwe mpaka mankhwala onse atsirizidwa.
Ndi njira yokongoletsedwerayi ndi yankho lachindunji, titha kugwira bwino mbali ya CNC yokhala ndi mipanda yopyapyala ndikupewa zovuta monga kupotoza, kupotoza, ndi kupindika. Zomangira zomangika zimalola kuti mbale yokhazikika ikhale yolumikizidwa mwamphamvu ku chogwirira ntchito, kupereka malo odalirika ndi chithandizo. Kuonjezera apo, kugwiritsa ntchito mbale yosindikizira kuti igwiritse ntchito kukakamiza kumalo opangidwa ndi makina kumathandiza kuti ntchitoyo ikhale yokhazikika.
Kusanthula Mwakuya: Momwe Mungapewere Kuwomberana Ndi Kusintha?
Kukwaniritsa kukonza bwino kwa zipolopolo zazikulu ndi zopyapyala zokhala ndi mipanda kumafuna kusanthula kwa zovuta zenizeni pakukonza makina. Tiyeni tione mwatsatanetsatane mmene mavutowa angathetsere bwinobwino.
Pre-machining Inner Side
Mu sitepe yoyamba yopangira (kukonza mbali yamkati), zinthuzo ndi chinthu cholimba chokhala ndi mphamvu zambiri. Choncho, workpiece savutika ndi machining anomalies monga mapindikidwe ndi warping pa ndondomekoyi. Izi zimatsimikizira kukhazikika komanso kulondola pokonza cholembera choyamba.
Gwiritsani Ntchito Njira Yotsekera ndi Kukanikiza
Pa sitepe yachiwiri (machining komwe kutentha kwakuya kuli), timagwiritsa ntchito njira yotsekera ndi kukanikiza. Izi zimatsimikizira kuti clamping force ndi yokwera komanso yogawidwa mofanana pa ndege yothandizira. Kuthirira uku kumapangitsa kuti chinthucho chikhale chokhazikika ndipo sichimazungulira nthawi yonseyi.
Njira Yina: Popanda Zomangamanga
Komabe, nthawi zina timakumana ndi zochitika zomwe sizingatheke kupanga wononga pobowo popanda chobowo. Nayi njira ina.
Titha kupangiratu zipilala zina panthawi yopangira mbali yakumbuyo kenako ndikuzigunda. Pamakina otsatirawa, timakhala ndi wononga kupyola mbali yakumbuyo ya chipangizocho ndikutseka chogwirira ntchito, kenako ndikukonza ndege yachiwiri (mbali yomwe kutentha kumatayidwa). Mwanjira imeneyi, titha kumaliza gawo lachiwiri la makina opangira kamodzi popanda kusintha mbale pakati. Pomaliza, timawonjezera gawo laling'ono lapatatu ndikuchotsa mizati kuti timalize ntchitoyi.
Pomaliza, ndi kukhathamiritsa ndondomeko ndi fixture yankho, tingathe bwinobwino kuthetsa vuto warping ndi mapindikidwe lalikulu, woonda zipolopolo mbali pa CNC Machining. Izi sikuti zimangotsimikizira kuti makinawo ali abwino komanso ochita bwino komanso amathandizira kukhazikika komanso kukhazikika kwazinthuzo.
