Mapangidwe akupanga kuwotcherera akupanga sizokhudza kuyika zitsulo pa benchi. Zimakhudza nthawi yolondola, kuwongolera mphamvu, komanso kumverana chisoni kwamakina pakati pa zida ndi gawo la geometry. Ku Botou Haijun Metal Products Co., Ltd., tapanga zida zopitilira 1,200 zowotcherera zopangira makasitomala opangira magalimoto, nyumba zopangira zida zachipatala, ndi zida zamagetsi zogula - chilichonse chimatsimikiziridwa ndi katundu weniweni, osati zongoyerekeza za CAD.
Chifukwa Chake Fixture Design Imapanga Kapena Imaphwanya Mphamvu Yanu Yowotcherera
Ma weld ambiri omwe alephera kutulutsa amabwereranso ku chipangizocho, osati nyanga, osati jenereta. Timaziwona mobwerezabwereza: kasitomala akuwonetsa mphamvu zowotcherera zosagwirizana, kutayikira kwa flash, kapena kupunduka kwa gawo. Amalowa m'malo mwa transducer, kukonzanso matalikidwe ake, ngakhale kusintha utomoni—kungozindikira chomwe chinayambitsa chigawocho. Makina opangidwa molakwika amabweretsa mitundu yogwedezeka yosalamulirika, kuthamanga kosagwirizana, kapena kupotoza kwa kutentha komwe kumakhala. Nyumba ya sensor ya kasitomala imodzi idasweka pamzere wowotcherera 37% ya nthawiyo. Zopangira zawo zimagwiritsa ntchito mbale za aluminiyamu zophwanyika popanda madera othandizira. Pambuyo pokonzanso maziko ndi kuuma kokhazikika komweko komanso mapini ofananira ndi 0.02 mm, kulephera kudatsika mpaka 0.8%.
Zolepheretsa zazikulu zakuthupi zimayendetsa chisankho chilichonse:
Resonance kupewa: Zosintha ziyenera kukhala zosachepera 5 kHz pafupipafupi kuti zipewe kugwirizana ndi kuzungulira kwa 20-40 kHz Kugawa kwa mphamvu ya clamp: Kupanikizika kuyenera kukhazikika mkati mwa ± 0.3 mm wa cholumikizira chowotcherera - osati kudutsa gawo lonselo Kudzipatula kwamafuta: Aluminiyamu 6061-T6 ntchito prototyping otsika mkombero; Chitsulo cholimba cha H13 ndichofunikira pa> 50,000 cycle Malamulo Asanu Osakambirana (Kuchokera Pamiyala Yopanga Yeniyeni)
Timakhazikitsa malamulowa pakuwunika kulikonse kojambula - osasiyapo:
Pezani choyamba, chepetsani kachiwiri: Gwiritsani ntchito kukwera kwa kinematic nsonga zitatu (mapini awiri a dowel + kagawo kamodzi) musanagwiritse ntchito mphamvu iliyonse yothina. Tayesa mpaka 0.15 mm lateral masinthidwe omwe amamangika tisanawapeze—zokwanira kusiyanitsa molakwika wowongolera mphamvu wa 0.5 mm. Fananizani za CTE ndi gawolo: Ngati kuwotcherera PC/ABS, pewani zitsulo zosapanga dzimbiri pokhapokha mutalipidwa. Kusagwirizana kwakukula kwa kutentha kumayambitsa kusintha kwapang'onopang'ono panthawi yobwerezabwereza. Kukonza kwathu kokhazikika? Inlay 304 malo osapanga dzimbiri m'matupi a anodized 6061-T6. Palibe zoyandama pafupi ndi zone yowotcherera: Malo aliwonse osatetezedwa mkati mwa 8 mm olowa amakhala ngati njira yogwedezeka yosakonzekera. Timayika malo onse opezeka pamalo amodzi - osawonjezeranso zoyika pambuyo pa makina. Kutolerana kwa nthawi yokhala ndi zinthu zofunika: Mpata wa 0.05 mm pakati pa gawo ndi maziko amachulukirachulukira kukhala 0.12 mm kupatuka pansi pa 2,500 N chotchinga. Timalongosola kutsika kwapansi ≤0.01 mm pamalo ogwirira ntchito-ndikutsimikizira ndi CMM tisanatumize. Kufikira kwautumiki > kukongola: Timayendetsa mizere yonse ya pneumatic mkati ndikugwiritsa ntchito zomangira za hex-key-ngakhale zitawonjezera masekondi 12 kuti tigwirizane. Akatswiri am'munda amalowetsa malo otopa mkati mwa masekondi 90. Mapangidwe "oyera" a mpikisano amafunikira kusokoneza kwathunthu ndikukonzanso. Zosintha za Off-the-Shelf Zikalephera—ndi Zoyenera Kuchita M'malo mwake
Magulu ena amayesa midadada ya generic aluminiyamu yokhala ndi zingwe zosinthika. Zimagwira ntchito - 300 mikombero. Kenako mapini a locator amavala, maziko ake amasinthasintha, ndipo kusinthasintha kwa weld kumawonongeka. Timatsata zowola izi: kutayika kobwerezabwereza ndi 17% pozungulira 1,200 pazida zomwe sizinali zolimba. Masamu ndi omveka bwino. Pakuyenda mayunitsi opitilira 5,000, kapangidwe kake kamene kamawotcherera kamene kamakhala kobweza m'malo osakwana 8 mosinthana ndi zochepa komanso nthawi yopumira.
Koma makonda sikutanthauza zovuta. Zosintha zathu zogwira mtima kwambiri zimatsata dongosolo losavuta:
Base mbale: 40 mm wandiweyani H13 chitsulo, kutentha kwa 48-52 HRC, pansi lathyathyathya mpaka 0.005 mm Locator system: Kuyika kwazitsulo zosinthika zosinthika, zosindikizira-zokwanira ndi kusokoneza kwa 0.002 mm Clamping mechanism: Masilinda a pneumatic okhala ndi masensa am'malo-palibe ma levers amanja Part ejection: Zikhomo zonyamulira zodzaza ndi masika zomwe zimayendetsedwa ndi mpweya wofanana ndi kukakamiza Kutsimikizika Kwamapangidwe Mungathe Kukhulupirira-Osati Kungoyembekeza
Chojambula si chojambula. Timatsimikizira mapangidwe onse m'magawo atatu:
Choyamba, kusanthula kwamachitidwe mu SolidWorks Simulation-kutsimikizira kuti palibe njira yolumikizira yomwe ilipo pakati pa 15-45 kHz. Chachiwiri, kuyesa kwa prototype pa Branson 2000X yathu yokhala ndi magawo enieni opanga ndi ma resin ambiri. Chachitatu, kuyezetsa moyo kwachangu: kuzungulira 10,000 weld pa 120% mphamvu mwadzina, kuyeza kavalidwe ka malo, kutembenuka koyambira, ndi kutsika kwamphamvu kwa weld shear.
Izi zidagwira choyipa kwambiri pagulu laposachedwa la sensor yaulimi. Kusanthula kwa ma modal kunasonyeza kuti pali 32.7 kHz - mkati mwa 0.3 kHz ya 33 kHz horn frequency. Popanda kuwongolera, resonance ikanakulitsa kuvala kwa nyanga ndi 4 ×. Tinawonjezera nthiti ziwiri zolimba za 8 mm-zotsimikiziridwa mu gawo lachiwiri loyesa. Kukonzekera komaliza kunapereka zokolola 99.94% yoyamba kudutsa mayunitsi 42,000.
Yambani Kumanja—Musanadutse Koyamba
Tibweretsereni gawo lanu losindikiza, chojambula cholumikizira cholumikizira, chandamale cha nthawi yozungulira, ndi voliyumu yapachaka. Pasanathe maola 72, mudzalandira lipoti la DFM lomwe likuwonetsa zofunikira kwambiri: kuyika kwa director director, kusintha kwa makulidwe a khoma, ndi zomwe zingayambitse kupsinjika. Palibe malonda. Palibe ma template a PDF. Ndemanga za uinjiniya zokha zomwe zidakhazikitsidwa zaka 14 zopanga zitsulo zozizira komanso kasamalidwe ka kulekerera kwa geometric.
Msonkhano wodalirika wa pulasitiki umayambira pomwe gawolo limakumana ndi zitsulo. Osati ndi malingaliro a pulogalamu-koma ndi data yokhazikika ya CMM, kukwera njinga zenizeni zapadziko lonse lapansi, ndi zida zomangidwira kuti zisunge kulolerana molimba kuposa momwe mukuumba. Umu ndi momwe mapangidwe awotcherera akupanga amasiya kukhala malo okwera mtengo - ndikukhala gawo lanu lamphamvu kwambiri lowongolera.
