Adalemba pa 2019-01-11Zinthu zitatu zamabizinesi, kuwongolera kumodzi komanso kuwiri kokhudzana ndi magwiridwe antchito ndikulimbikitsa opanga zomangira, zomata ndi masitampu ang'onoang'ono okhudzana ndi kugwiritsa ntchito ukadaulo wa dip spin coating.
Choyamba, oyang'anira zachilengedwe akupitilizabe kuyang'ana pa plating.Chachiwiri, chiwerengero ndi kuchuluka kwa ntchito zomwe zimafuna kuti ntchito yophimba kwambiri ikhale yopopera mchere, chiwerengero cha Kesternich ndi kusagwirizana kwa torque kukuwonjezeka.Kupaka zokutira dip spin pa mbale yopyapyala ya zinki kuti mutseke zinki ndi yankho lomwe ndi lothandiza komanso lotsika mtengo.Zotsatira zoyezetsa zopopera mchere zitha kukulitsidwa kuchokera ku maola 120 mpaka 1,000 pogwiritsa ntchito njirayi.Ndikwabwinonso kuposa njira zina zambiri malinga ndi chilengedwe.Pomaliza, hydrogen embrittlement ndi nkhawa nthawi zonse, ndipo dip / spin yawonetsa kuthekera kochepetsera kapena kuthetsa vutoli.
Dip spin ndi njira yomwe mankhwala amaikidwa mudengu la mauna, kuviikidwa muzitsulo zokutira ndikupota kuti achotse zokutira zochulukirapo.Kutentha ndi kukhuthala kwa zokutira, nthawi yomiza, kuyendayenda kwa ma spin ndi ma velocities ndi njira yochiritsira ndi zina mwazosintha zomwe zimalola ogwiritsa ntchito kusintha ndondomeko ya ndondomeko ndikupeza zotsatira zolondola, zobwerezabwereza kwambiri.
Chodziwikanso ndi kuthekera kwa dip/spin kuchepetsa mtengo wazinthu zonse zokutira komanso kutaya zinyalala.Izi ndichifukwa chaukadaulo wa 98 pct kapena kupitilira apo pakusamutsa bwino.
Makina a Dip spin monga omwe amapangidwa ndi Spring Tools, Portage, Michigan, ndiwopindulitsa kwambiri pazigawo zing'onozing'ono zokhala ndi ma contours ena komanso zomwe zitha kukutidwa mochulukira popanda kumamatira.Ndipo ngakhale pali zosiyana zodziwika bwino (wopanga zomangira m'modzi amakonza mabawuti ake okulirapo kuti akonzere dip/spin), magwiridwe antchito amakwaniritsidwa ndi zigawo zomwe zimakhala mainchesi 10 kapena kuchepera komanso zosakwana mainchesi awiri m'mimba mwake.
Ngakhale ma washers ndi zigawo zina zathyathyathya zimakutidwa bwino ndi njira zina, dip / spin ndiyoyenera kuyika padenga ndi zomangira zina, zomangira, akasupe, mphete za o, u-bolts, misomali ndi zomangira, zokwera zamagalimoto ndi zida zina zambiri zomwe zimagwiritsidwa ntchito. kwa kumaliza kwamakina.
Ukadaulo wa Dip spin umagwirizana ndi mitundu yonse yayikulu yokutira yomwe imagwiritsidwa ntchito pomaliza komaliza;makamaka, zokutira zomwe zimaphatikiza kukana kwambiri kwa mankhwala ndi galvanic / bi-metallic corrosion ndi kukhazikika kwa UV, anti-galling properties ndi / kapena anti-vibration.Zambiri zitha kukhala zogwirizana ndi zosindikizira, zomatira ndi zotchingira zotsekera ndipo zimatha kuuma mpaka kukhudza zikachiritsidwa.Mitundu yeniyeni yokutira yomwe imakhudzidwa imaphatikizapo ma fluorocarbons, zinki wolemera, zitsulo za ceramic (zopangidwa ndi aluminiyamu ndi topcoat organic kapena inorganic topcoat) ndi makina opangidwa ndi madzi.
Dongosolo la dip spin limaphatikizapo njira zitatu: 1) Kuyeretsa ndi kusamalidwa;2) zokutira ntchito;ndi 3) Kuchiza.Opanga zomangira nthawi zambiri amagwiritsa ntchito grit ya 80- mpaka 100-mesh aluminium oxide kuchotsa ma oxides ndi masikelo opangira kutentha.Micro-, medium- kapena heavy-crystalline zinc phosphate ndiye njira yoyamikiridwa ngati ikufunika, ngakhale pali zokutira zingapo za dip / spin zomwe zitha kuyikidwa pazitsulo zopanda kanthu.
Akaumitsa, zigawo zake zimayikidwa mudengu lokhala ndi waya.Ngati kutsitsa kumangochitika zokha, makinawo amatumiza magawo ku sikelo yoyezera yokhala ndi masikelo okhazikitsidwa kale.Pambuyo potsitsa, magawo amasamutsidwa m'chipinda choviika / chozungulira ndikulowera papulatifomu yozungulira pomwe amatsekedwa.Chophimbacho, chomwe chili pansipa, chimakwezedwa kuti chilowetse mtanga wa zigawozo.
Nthawi yomiza ikatha, chidebe chophikiracho chimatsika mpaka dengu likadali mumtsuko, koma pamwamba pa madziwo.Kenako dengulo limapangidwa ndi centrifuged.
Kuzungulira kozungulira kutha kukhala njira imodzi kwa 20 mpaka 30 sec, brake yodzaza, kenako kuzungulira kwanthawi yofanana.Ma braking action amawongoleranso zigawo kuti zichotse bwino zomatira kumkati.Dip/spin ikatha, chotengeracho chimatsitsidwa ndipo dengu limasinthidwanso, limatsegulidwa ndikuchotsedwa.Kutsegulanso kumachitika ndipo ndondomekoyi imabwerezedwa.
Zinthu zokutira zimayikidwa mu chotengera chachitsulo ndikulowetsedwa ndikuchotsedwa kudzera pakhomo lolowera mbali.Kusintha kwamitundu kumachitika mu 10 mpaka 15 min ndikungochotsa chotengera choyambirira ndi dengu ndikuyika zatsopano.Zovala zimasungidwa mu chidebe cha dip / spin, chomwe chimasindikizidwa ndi chivindikiro chachitsulo kapena polyethylene.Madengu a mauna amatsukidwa pogwiritsa ntchito soak kapena grit blast kapena ma mesh liner okha amawotchedwa mu uvuni woyaka moto.
Zopaka zochepa zomwe zimagwiritsidwa ntchito pomanga zowumitsa mpweya.Kwa 90 pct kuphatikiza zomwe zimafuna kutentha, mizere yaying'ono ya dip / spin imaphatikizapo uvuni wa batch;zida zazikuluzikulu zimakhala ndi uvuni wamalamba wotumizira.Malamba oyendetsa amakula mpaka magawo.Mbali zokutidwa zimayikidwa mwachindunji pa lamba wa uvuni ndikufalikira pamanja m'lifupi mwake.Kapena, amatsitsidwa pa tray yogwedezeka yomwe imayika magawo pa lamba wa uvuni.
Njira zochiritsira zimachokera ku 5 mpaka 30 min;kutentha kwachitsulo kwapamwamba kwambiri ndi 149 mpaka 316F.Malo ozizirirapo mpweya wokakamiza amabweretsa kutentha kwa zinthu pafupi ndi malo ozungulira.
Zida za Dip spin zimapangidwa mokulirapo kuti zigwirizane ndi zofunikira.Kumene magulu azinthu ali ang'onoang'ono ndipo kusintha kwamitundu kumafunikira, kachitidwe kakang'ono, kadengu kakang'ono ka mainchesi 10, mphamvu ya 750 lb/hr ndi liwiro lozungulira kuchokera ku ziro kufika pa 900 rpm kungalimbikitse.Dongosolo lamtunduwu limagwira ntchito pamanja, pomwe woyendetsa amanyamula dengu ndikugwiritsa ntchito dip ndi kupota magawo amizeremizere pogwiritsa ntchito ma valve m'manja kapena ma automation ang'onoang'ono pomwe kutsitsa / kutsitsa kumayendetsedwa pamanja, koma kuzungulira kumayendetsedwa ndi PLC.
Makina apakati, oyenera masitolo ambiri ogwira ntchito amagwiritsa ntchito dengu la mainchesi 16 m'mimba mwake ndi voliyumu yogwiritsidwa ntchito ya cu ft imodzi. Mphamvu ndi pafupifupi 150 lbs.Dongosololi limatha kupanga mpaka 4,000 lbs/hr pazamankhwala komanso kuthamanga kwa 450 rpm.
Opanga ma fasteners akulu kwambiri komanso malo ogulitsira ntchito nthawi zambiri amatumizidwa bwino ndi makina ogwiritsira ntchito dengu la mainchesi 24 ndipo amakhala ndi liwiro lofikira mpaka 400 rpm.
