Kuchepetsa Aluminium Brazing ndi Computer Assisted

Kuchepetsa Aluminium Brazing ndi Computer Assisted

Kuchepetsa kutayikira kwa aluminium chikuchulukirachulukira m'makampani. Chitsanzo chabwino ndikumanga mapaipi osiyanasiyana pagalimoto yosinthira magalimoto. Pulogalamu ya kutentha kotentha yogwiritsidwa ntchito kwambiri pamtunduwu ndiosazungulira imodzi, yomwe imatha kutchedwa kalembedwe ka "Horseshoe-hairpin". Kwa ma coil awa, maginito omwe amachititsa kuti magawidwe azipezekanso pano ali ndi 3-D mwachilengedwe. Pakugwiritsa ntchito kumeneku, pali zovuta zamtundu wolumikizana komanso kusasinthasintha kwa zotsatira kuchokera mbali imodzi mpaka mbali. Pofuna kuthana ndi vuto limodzi kwa wopanga magalimoto akuluakulu, pulogalamu yofanizira makompyuta ya Flux3D idagwiritsidwa ntchito pophunzira ndikuwongolera. Kukhathamiritsa kunaphatikizaponso kusintha koyilo yochotsereka ndi kasinthidwe kazitsulo kazitsulo. Ma coil atsopano, omwe amayesedwa mozama mu labotale, amapanga magawo okhala ndi ziwalo zapamwamba kwambiri m'malo opangira angapo.

Galimoto iliyonse imafunikira chosinthira kutentha zingapo (zotenthetsera, ma evaporator, ma condensers, ma radiator, ndi zina zambiri) kuti kuziziritsa mphamvu yamagetsi, kuziziritsa mpweya, kuzirala kwamafuta, ndi zina zotero. Ambiri omwe amasinthitsa kutentha kwa magalimoto masiku ano amapangidwa ndi aluminiyamu kapena aluminiyamu. Ngakhale injini imodzimodziyo itagwiritsidwa ntchito popanga mitundu ingapo yamagalimoto, malumikizowo amatha kusiyanasiyana chifukwa cha mawonekedwe osiyanasiyana pansi pake. Pachifukwa ichi, ndichizolowezi choti opanga magawo amapanga matupi angapo osinthira kutentha kenako ndikulumikiza zolumikizira zosiyanasiyana pantchito yachiwiri.

Matupi osinthanitsa kutentha nthawi zambiri amakhala ndi zipsepse za aluminiyamu, machubu ndi mitu yolumikizidwa m'ng'anjo. Pambuyo polimba, zotenthetsera zimasinthidwa pamtundu wagalimoto pomata matanki a nayiloni kapena mapaipi amtundu wa aluminium osiyanasiyana. Mapaipi awa amalumikizidwa ndi MIG kuwotcherera, lawi kapena kulowetsa. Pankhani yolimba, kutentha koyenera kumafunikira chifukwa chakuchepa kwakanthawi kosungunuka ndi kutentha kwa aluminiyamu (20-50 C kutengera aloyi, chitsulo chodzaza ndi mpweya), kutentha kwambiri kwa aluminiyamu komanso mtunda woyandikira wina mafupa omwe adalumikizidwa pantchito yapita.

Kutentha Kwambiri ndi njira yodziwika bwino yolimbira mapaipi osiyanasiyana kuti mutenthe ma mutu osinthanitsa. Chithunzi 1 ndi chithunzi cha kusinthitsa set for up for brating a pipe to a tube on a heat exchanger header. Chifukwa cha zofunikira pakuwotcha bwino, nkhope ya coil induction iyenera kukhala pafupi kwambiri ndi cholumikizira chomwe chingakhale brazed. Chifukwa chake koyilo ya cylindrical yosavuta singagwiritsidwe ntchito, chifukwa gawolo silinachotsedwe olumikizanawo atalimba.

Pali mitundu iwiri yayikulu yopangira ma coil yomwe imagwiritsidwa ntchito polimbira izi: Omwe amathandizira "Clamshell" amafanana ndi ma inductors a cylindrical, koma amatseguka kuti alole gawo kuchotsedwa. Othandizira "Horseshoe-hairpin" amapangidwa ngati kansalu ka akavalo kuti azitsitsa gawolo ndipo kwenikweni ndi ma coil opangira tsitsi mbali zotsutsana za olowa.

Ubwino wogwiritsa ntchito "Clamshell" inductor ndikuti Kutentha kumakhala kofanana mozungulira komanso kosavuta kulosera. Chosavuta cha "Clamshell" inductor ndikuti makina ofunikira amafunika kukhala ovuta kwambiri ndipo omwe adalumikizana nawo pano ndi osadalirika.

Othandizira "Horseshoe-hairpin" amatulutsa kutentha kovuta kwambiri kwa 3-D kuposa "Clamshells". Ubwino wogwiritsa ntchito kalembedwe ka "Horseshoe-hairpin" ndikuti gawo lomwe limagwira ndi losavuta.

Induction Aluminum Brazing

Kuyimira kwamakompyuta kumakwaniritsa kulimba

Wopanga chida chachikulu chotenthetsera kutentha anali ndi mavuto abwinobwino polimbitsa cholumikizira chomwe chikuwonetsedwa mu mkuyu. 1 pogwiritsa ntchito choyezera chopangira kavalo. Mgwirizano wa braze unali wabwino kwa mbali zambiri, koma kutentha kumakhala kosiyana kwambiri ndi magawo ena, kumapangitsa kuchepa kophatikizana, kulumikizana kozizira komanso chitsulo chodzaza khoma la chitoliro chifukwa chakutentha kwamderalo. Ngakhale poyesa chilichonse chosinthanitsa kutentha kuti chituluke, magawo ena adatayikirabe pachilumikizachi. Center for Induction Technology Inc. idapatsidwa mgwirizano kuti athe kusanthula ndi kuthana ndi vutoli.

Mphamvu yomwe imagwiritsidwa ntchito pantchitoyi imakhala ndi mafupipafupi a 10 mpaka 25 kHz ndikuwonetsa mphamvu ya 60 kW. Pakukonza brazing, wogwiritsa ntchito amalowetsa mphete yazitsulo kumapeto kwake ndikulowetsa chitolirocho mkati mwa chubu. Wosinthanitsa kutentha amaikidwa pachitsulo chapadera ndikusunthira mkati mwa cholowetsa nsapato.

Dera lonse lolimbikira limadulidwa kale. Pafupipafupi momwe amagwiritsira ntchito kutentha gawolo nthawi zambiri ndi 12 mpaka 15 kHz, ndipo nthawi yotentha imakhala pafupifupi masekondi 20. Mulingo wamagetsi udakonzedwa ndikuchepetsa kocheperako kumapeto kwa kutentha. Pyrometer yowoneka bwino imazimitsa mphamvuyo kutentha kwakumbuyo kwakanthawi kwa chophatikizira kukafika pamtengo wokonzedweratu.

Pali zinthu zambiri zomwe zingayambitse kusagwirizana komwe wopanga anali kukumana nako, monga kusiyanasiyana kwa zinthu zophatikizana (kukula kwake ndi malo ake) komanso kusakhazikika komanso kusinthasintha (munthawi) kukhudzana kwamagetsi ndi matenthedwe pakati pa chubu, chitoliro, mphete yodzaza, ndi zina. ali osakhazikika mwachibadwa, ndipo kusiyanasiyana kwakung'ono kwa izi kumatha kuyambitsa machitidwe osiyanasiyana. Mwachitsanzo, mphete yachitsulo yotseguka imatha kumasuka pang'ono pang'ono pansi pamagetsi amagetsi, ndipo mathero omasuka a mpheteyo amatha kuyamwa mmbuyo ndi mphamvu yama capillary kapena osasungunuka. Zinthu zaphokoso ndizovuta kuchepetsa kapena kuthetsa, ndipo yankho lavutoli limafunikira kukulitsa kulimba kwa zonsezo. Kuyimira kwamakompyuta ndi chida chothandiza pofufuza ndi kukonza njirayi.

Pomwe pakuwunika kwa brazing, mphamvu zamphamvu zamagetsi zimawonedwa. Pakadali pano magetsi ayatsidwa, koyilo ya akavalo ikuwonekeratu kuti ikukula chifukwa chogwiritsa ntchito mphamvu zamagetsi zamagetsi mwadzidzidzi. Chifukwa chake, inductor adalimbikitsidwa mwamphamvu, kuphatikiza kuphatikiza mbale yowonjezera ya fiberglass (G10) yolumikiza mizu yama coil awiri opangira tsitsi. Chizindikiro china cha mphamvu zamagetsi zomwe zidalipo ndikusintha kwachitsulo chosungunuka kutali ndi madera oyandikira mkuwa komwe maginito amakhala olimba. Mwanjira yokhazikika, chitsulo chodzaza chimagawa chimodzimodzi mozungulira cholumikizacho chifukwa champhamvu yamagetsi ndi mphamvu yokoka mosiyana ndi njira yachilendo pomwe chitsulo chodzaza chimatha kutuluka olumikizana kapena kukwera pamwamba pa chitoliro.

chifukwa kulowetsa aluminiyumu kumangirira ndichinthu chovuta kwambiri, sizingatheke kuyerekezera kuyerekezera kolondola kwa unyolo wonse wazinthu zogwirizana (zamagetsi, zamagetsi, zamakina, hydrodynamic ndi metallurgical). Njira yofunikira kwambiri komanso yowongolereka ndikupanga magetsi opangira magetsi, omwe adayesedwa pogwiritsa ntchito pulogalamu ya Flux 3D. Chifukwa cha zovuta zakapangidwe kabwino ka brazing, kuphatikiza kwa kuyerekezera kwamakompyuta ndi zoyeserera kunagwiritsidwa ntchito pakupanga makina ndi kukhathamiritsa.
