Pamene mainjiniya afotokoza mpweya woyika mchenga kuponyera pazigawo zazitsulo zolondola, iwo sakusankha njira ya cholowa-akusankha njira yotsimikiziridwa, yokhazikika pazigawo zomwe ziyenera kupulumuka kupsinjika kwakukulu, kuyendetsa njinga zamoto, ndi kuvala kwa abrasive. Mosiyana ndi mchenga wobiriwira kapena utomoni wosaphika, kuponyera mchenga kumadalira chinyontho cha mumlengalenga ndi kutentha kozungulira kuti kuchiritse chomangiracho—palibe mavuni, zopangira zinthu, palibe mpweya wokakamiza. Kuphweka kumeneku kumabisa luso lenileni laukadaulo: kukwaniritsa kulolerana kwa ± 0.15 mm pampopi ya 300-mm cobalt alloy sikutanthauza "kungogwiritsa ntchito mchenga." Zimakhudza kuwongolera kwa chemistry, kubwereza kwa nkhungu, kusungika kwa geometry panthawi yogwedezeka, komanso kukhazikika kwapambuyo pakupanga makina.
Taponya ma nozzles opitilira 12,000 AMS 5387 a aloyi m'zaka zitatu zapitazi-iliyonse ili ndi makulidwe a khoma pansi pa 4.2 mm ndi ndime zoyenda mkati zomwe zimafuna kutsata kwa CMM-Verified GD&T. Pagulu lililonse, njira yokhazikitsira mpweya imabweretsa kupsinjika kotsalira kotsalira kuposa njira zina zomangira utomoni, kuchepetsa kupotoza kwa pambuyo-machining ndi 37% panyumba za silinda zapampu ya piston. Izi sizongoyerekeza. Imayezedwa pamakina athu oyezera a Zeiss CONTURA G2, olowetsedwa pagawo lililonse, owoneka ndi manambala a kutentha kwapawiri ndi ma ID a nkhungu.
N’chifukwa chiyani zimenezi zili zofunika? Chifukwa kuponyera mchenga wopangidwa ndi mpweya sikubwereranso - ndi njira yothandizira ma geometri ofunikira kwambiri pomwe kukhulupirika kwa microstructure ndi kulosera zam'mbali zimaposa liwiro laiwisi. Ganizirani za hydraulic pressure valve body: yopangidwa kuchokera ku chitsulo chosapanga dzimbiri, zingatenge maola 18 a mphero zambirimbiri ndikupanga 62% zinyalala zakuthupi. Kuponyedwa kudzera mumchenga wa mpweya, mawonekedwe apafupi ndi ukonde amafika ndi 92% ya misa yomaliza, porosity yochepa yamkati (ASTM E155 Level 2), ndi yunifolomu dendritic spacing yotsimikiziridwa ndi metallographic cross-section. Chotsatira? Mtengo wotsika, nthawi yocheperako, komanso - movutikira - kukana kutopa kwabwinoko pamakwerero okwera pamwamba pa mipiringidzo 420.
- Kukhulupirika kwakuthupi: Zomangira mpweya (zomwe nthawi zambiri zimakhala ndi sodium silicate + CO₂ activator kapena organic ester systems) zimabweretsa chithunzithunzi cha kaboni chosasamala. Izi zimateteza mazenera olimba a chemistry omwe amafunikira ma aloyi a T800 a cobalt-pomwe ngakhale 0.03% ya kaboni yochulukirapo imawononga kuuma kotentha.
- Kukhazikika kwa nkhungu: Kupanda kutulutsa mpweya kumatanthauza kusagwedezeka kwa kutentha kwa nkhungu panthawi yothira. Nthawi zambiri timatsanulira 1100 ° C wosungunuka wa cobalt-nickel mu nkhungu zomwe zimasungidwa pa 22-28 ° C pozungulira - popanda matuza, popanda mitsempha ya pamwamba.
- Dimensional kusasinthasintha: Kukula kwa nkhungu ndikodziwikiratu komanso kutsata mzere. Pa makina opangira makina opangira ma winch center shaft rollers (OD 215 mm, kutalika 480 mm), timakhala mozungulira mkati mwa 0.08 mm kudutsa ma 100-unit lots-popanda kuchepetsa nkhawa.
Ena angatsutse kuti mchenga woyika mpweya ulibe mapeto opangira ndalama. Zoona, koma kuuma kwapamtunda Ra 6.3 µm ndi yokwanira kukweretsa malo ogwirira ntchito pa maziko a pampu ndi ma valve ochuluka. Kumene kumalizidwa kuli kofunikira, timaphatikiza kulondola kwa CNC kutembenuka *pambuyo* kuponya—osati kale. Kutsatira kumeneku kumapewa kupotoza kwa makina kuchokera pakuchepetsa kupsinjika kotsalira. Timapewanso msampha wamba wonena mopitilira muyeso mphamvu zomangira: sodium silicate yochulukirapo imawonjezera kuwonongeka kwa nkhungu komanso chiwopsezo chosweka pakagwiridwe. Kupanga kwathu koyenera kumagwiritsa ntchito 3.8% binder ndi kulemera kwake, kuchiritsa mphindi 45 pa 55% RH-yovomerezeka m'miyezi itatu ya chinyezi cha Qingdao.
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yathu mpweya wokhazikika mchenga kuponyera fakitale imagwira ntchito ngati mfundo imodzi mumayendedwe ogwirizana kwambiri - osati malo akutali. Makasitomala akatumiza chojambula cha pulagi ya cobalt alloy yosakhala wamba, njira yathu imayamba ndikuwunikanso zitsulo: Kodi AMS 5387 ndiye giredi yoyenera - kapena kusinthidwa kwa T800 kungapereke kukana kwamphamvu kwamadzi amchere? Kenako pamabwera chifaniziro cha nkhungu: Kodi khomo lolowera liyenera kudyetsa gawo lokhala ndi mipanda yopyapyala khungu lisanawume? Pokhapokha timapanga mapangidwe, kusakaniza mchenga, ndikutsanulira. Gawo lililonse limabwezeretsanso deta mu ISO 9001-certified quality loop-cert cert, mipiringidzo yolimba yoyesedwa pa ASTM A781, kuyang'ana kwa akupanga kumakoma onse> 25 mm wandiweyani.
Kuphatikiza uku kumapereka zomwe ogula amafunikiradi: magawo omwe amakwanira, amagwira ntchito, komanso omaliza - osati magawo omwe amatumiza. Kwa zida zamafuta aku North America OEMs, izi zikutanthauza kuti ma valve opanikizika omwe amakhala ndi mizere 12,000 pa 350 ° F popanda kutayikira. Kwa omanga magalimoto aku Europe, zikutanthauza kuti ma roller a winch shaft amakhalabe okhazikika pambuyo pa maola 500 akuyendetsa njinga. Kwa ophatikiza pampu akumwera chakum'mawa kwa Asia, zikutanthauza kuti nyumba za silinda zikufika zokhala ndi makina opangidwa kale mkati mwa ± 0.05 mm - okonzeka kusonkhana komaliza, osati kukonzanso.
Ngati mukuwunika ogulitsa kuti awonetsedwe molondola, funsani mafunso atatu: Kodi angasonyeze malipoti a CMM a geometry yanu yeniyeni - osati zitsanzo zamtundu uliwonse? Kodi amawongolera kusakanikirana kwa ma binder, kuchiritsa nkhungu, ndi ma shakeout mu nthawi yeniyeni - kapena kudalira luso la opareta okha? Ndipo kodi amalumikiza deta yotumizira ku gawo lomaliza pakugwiritsa ntchito m'munda? Pamalo athu, yankho kwa onse atatu ndi inde-ndipo zolembedwa muzolemba zilizonse zopanga. Kulondola sikutheka m'malo opangira makina. Zimayambira mumchenga.
