Ogula ambiri kapena mainjiniya ena akamva za 'OEM sand casting', amawonetsa gawo loyambira, loyipa, lotsika mtengo. Ndilo lingaliro lolakwika loyamba komanso lalikulu. Sikuti amangopanga makope otchipa; Ndi za luso loyambira, njira zosunthika kwambiri zoperekera zigawo zogwira ntchito, zodalirika pa kuchuluka kwake. Luso lenileni lagona pa kudziwa nthawi yoigwiritsa ntchito, momwe mungaipangire, komanso momwe mungasinthire kuti ikwaniritse zomwe nthawi zambiri zimadabwitsa anthu.
Kusinthasintha Kosamvetsetseka kwa Mchenga
Tiyeni tinene mwachindunji. Kusinthasintha sikungokulirakulira - ngakhale inde, mutha kuponyera bulaketi yaying'ono kapena bedi lalikulu la makina. Ndi za kusinthika kwa zinthu ndi kusintha kwa mapangidwe. Ndagwirapo ntchito zomwe kasitomala anabwera kwa ife ndi a OEM mchenga kuponyera kapangidwe ka chitsulo cha ductile, koma titawunikanso katundu ndi mawonekedwe amavalidwe, tidapereka lingaliro losintha kukhala chitsulo chopanda aloyi. Zida - chitsanzo - chinakhalabe chimodzimodzi, koma kusintha kwa zinthu mumchenga kunapatsa gawolo moyo wautali wa 40%. Ndiwo mtengo womwe simumapeza pongogula mtengo wotsika kwambiri.
Chitsanzo palokha ndi zokambirana zonse. Mapangidwe amitengo a prototypes kapena mathamangitsidwe amfupi, urethane kwa zidutswa mazana angapo, ndipo pamapeto pake machitidwe achitsulo opangira makumi masauzande. Gawo lirilonse ndi mtengo poyerekeza ndi chisankho cha voliyumu. Ndawonapo makampani akuwotcha ndalama polumphira ku zida za aluminiyamu kuti apange magawo 500, osazindikira kuti mtengowo ukanadzilipira kakhumi. Mapangidwe a gating system mu nkhungu yamchenga ndi luso lina lobisika. Kusayenda bwino kumabweretsa kuchepa, kutsekeka kozizira, ndi kuwonongeka kwachitsulo. Si chinachake inu angwiro kuchokera buku; ndi chifukwa chowona nkhungu zambiri zikutsanuliridwa ndikudula zidutswazo kuti awone chomwe chalakwika.
Apa ndi pamene zokumana nazo za foundry zimatiuza. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi zaka makumi ambiri akujambula, akumvetsa kusiyana kumeneku. Iwo sali chabe a kuponya mchenga shopu; kugwira ntchito kwawo kwanthawi yayitali kumatanthauza kuti amamanga ndikubwereza masauzande amitundu. Kudziwa kwamabungwe momwe mungayendetsere gawo mu nkhungu, komwe mungayike zokwera, komanso momwe mungasinthire ma aloyi osiyanasiyana ndizomwe mukulipira.
Kumene Ikuyenera (ndipo Pomwe Siikuyenera)
Ndiye liti OEM mchenga kuponyera kuyimba koyenera? Kwa ma geometries ovuta, amodzi kapena ochepa muzitsulo zachitsulo, nthawi zambiri zimakhala zosagonjetseka. Ganizirani zigawo zazikulu zamakina, nyumba zapampu, kapena matupi akuluakulu a valve. Kumapeto kwake kumakhala kovutirapo kuposa kuyika ndalama, ndipo kulolerana kwapang'onopang'ono kumakhala kokulirapo - nthawi zambiri kumakhala +/- 0.5mm pamlingo wa 100mm, kutengera. Simungayembekezere kugwira gawo lakhumi la millimeter. Ngati mukufuna izo, mukuyang'ana mautumiki awo ena monga CNC makina monga ntchito yachiwiri, zomwe ndizo zomwe wothandizira ophatikizidwa amapereka.
Ndikukumbukira pulojekiti yopanga ma hydraulic manifold. Mapangidwe oyambirira anali opangidwa ndi zitsulo zopangidwa ndi zitsulo. Nthawi yotsogolera inali yayitali, kusokonekera kwa kuwotcherera kunali kowopsa, ndipo kuyesa kukakamiza kunali ndi kutayikira. Tinalipanganso kukhala limodzi kuponya mchenga mu zitsulo zotayidwa. Magawo ofunikirawo adayikidwa mumchenga, ndikuchotsa ma welds ambiri. Pamwamba ngati-cast iyenera kuyeretsedwa, koma malo osindikizira adapangidwa ndi makina a CNC. Zotsatira zake zinali zamphamvu, zotsimikizira kutayikira pamtengo wotsikirapo wa voliyumu yofunikira. Chinsinsi sichinali kuwona kuponya mchenga ngati yankho lonse, koma ngati njira yabwino yoyambira.
Mlandu wolephera? Kuyesera kugwiritsa ntchito ma geometrium okhala ndi mipanda yopyapyala komanso yodabwitsa kwambiri. Nthawi ina tinayesa nyumba zosefera zosapanga dzimbiri zokhala ndi nthiti zambiri zabwino. Mchengawo sunathe kulongedza bwino m’mabowo ang’onoang’ono, zomwe zimachititsa kuti tiziumba ting’onoting’ono ting’ono ting’ono ting’ono ting’ono. Zokololazo zinali zoipa kwambiri. Tidasinthira ku chipolopolo chopangira ntchitoyo - njira yomwe QSY imatchulanso, yomwe kwenikweni ndi mchenga woyengedwa bwino pogwiritsa ntchito mchenga wokutidwa ndi utomoni kuti mumve zambiri. Kudziwa malire a ndondomekoyi kunapulumutsa polojekitiyo.
The Critical Link: Foundry ndi Machining
Ili ndi gawo lomwe ambiri amanyalanyaza. A yaiwisi kuponya mchenga pafupifupi si gawo lomaliza. Mufunika makina opangira mabowo a bawuti, malo osindikizira, ndi miyeso yovuta. Ngati wothandizira wanu ali wosiyana ndi malo ogulitsira makina, mukubweretsa vuto. Kusintha kwa ma benchmarks a dimensional, mayendedwe amawonjezera mtengo, ndipo kuloza chala kumayamba pomwe kuponya sikungatheke.
Ntchito yophatikizika imasintha chilichonse. Tengani chitsanzo kuchokera ku mbiri ya QSY: amapereka zonse zoponya ndi CNC makina. Izi zikutanthauza kuti makina gulu ntchito ndi foundry kuchokera chitsanzo siteji kapangidwe. Atha kulangiza pakuwonjezera makina opangira zinthu m'malo oyenera, kupewa zinthu zovuta zomwe zili pafupi ndi mizere yolekanitsa, ndikuwonetsetsa kuti kuponyerako kuli ndi kukhulupirika kwadongosolo kuti athe kupirira mphamvu zomenyera panthawi ya mphero. Gawoli limapangidwa kamodzi paulendo wonse wopanga.
Tinaphunzira izi movutikira kale. Anapereka gulu la ma ductile iron gearbox housings kumalo ogulitsira makina. Sitoloyo idadandaula za kuvala kwa zida ndi mawanga olimba. Zinapezeka kuti kuzizira mu nkhungu zathu zamchenga sikunali kofanana, zomwe zimapangitsa kuti pakhale kusiyana pang'ono kwa microstructure m'magawo ena. Okonza makinawo anali kugunda malo olimba kwambiri. Tikadakhala pansi pa denga limodzi, mayankho akadakhala nthawi yomweyo-kusintha kuziziritsa, mwina kusintha kachitidwe kanoculant-ndikuthetsedwa gulu lonse lisanatsanulidwe. Tsopano, nthawi zonse timagogomezera kufunika kwa wothandizira yemwe amawongolera njira zonse ziwiri.
Zofunika Kuposa Tsamba Lapadera
Makasitomala amapereka giredi yakuthupi ngati ASTM A216 WCB ndikuganiza kuti ntchito yatha. Mu kuponya mchenga, kalasi ndi chiyambi chabe. Mchitidwe wosungunula, kuthira ma ladle, kutentha kothira mu nkhungu yamchenga - izi zimatanthauzira mawonekedwe enieni a zinthu. Kuthekera kwa opeza okhala ndi ma aloyi apadera, monga ma nickel-based kapena cobalt omwe QSY amatchula, ndi chizindikiro champhamvu chowongolera zitsulo. Ma alloys awa ndi osakhululuka; kutentha kolakwika kapena kuipitsidwa mu nkhungu yamchenga kungawononge kusungunuka.
Mwachitsanzo, kutsanulira chitsulo chochuluka cha chromium chokana abrasion. Mukathira kutentha kwambiri mumchenga, mutha kuzizira - kupanga zolimba kwambiri, zonyezimira pamwamba pomwe, zomwe zimatha kugwira ntchito. Mukathira mozizira kwambiri, mumapeza mistruns. Zenera ndi lopapatiza. Zimakhudza kumverera ndi deta: kuyang'ana kayendedwe kachitsulo, kuyang'ana kuwerengera kwa thermocouple, ndikudziwa momwe mchenga wanu umatenthera. Izi sizongochitika zokha; ndi luso la woyambitsa.
Izi zimafikira ku chithandizo cha kutentha pambuyo poponya. A kuponya mchenga gawo nthawi zambiri limatuluka ndi zotsalira zotsalira komanso ma microstructure omwe sali abwino. Kukhazikika, kuzimitsa ndi kutenthetsa - izi nthawi zambiri zimakhala zofunikira pakuchita bwino. Wopereka chithandizo chonse azikhala ndi izi mkati kapena aziyendetsedwa molimba. Simukufuna kuponyera kwanu kochepetsa nkhawa mutakhala mgalimoto kwa milungu iwiri musanayambe kukonza, zomwe zitha kutenga zovuta zatsopano.
Chowonadi cha OEM: Kusagwirizana pa Volume
OEM mu OEM mchenga kuponyera kutanthauza kupanga kobwerezabwereza. Ichi ndi gawo lovuta kwambiri. Kupanga kuponya kumodzi kwabwino ndikosavuta. Kupanga 10,000 kukhala yofanana ndi yoyamba ndizovuta. Kuwonongeka kwa mchenga, kuvala kwa mapangidwe, ndi ng'anjo zamoto zimasintha. Kuwongolera njira ndi chilichonse. Zikutanthauza kuyendera mosamalitsa kwa mawonedwe a nkhani yoyamba, osati zigawo zomaliza. Zimatanthawuza kuyezetsa kowononga nthawi ndi nthawi-kudula kuponya kuti muwone kumveka kwamkati ndi microstructure-ngakhale panthawi yoyendetsa.
Dongosolo lothandiza lomwe timagwiritsa ntchito ndikuwongolera njira zowerengera pamiyeso yayikulu kuchokera ku magawo oponyedwa, tisanapange makina. Mukuwona mayendedwe. Ngati malo obowola ayamba kugwedezeka, mwina mbale zapatani zavala kapena makina omangira amafunika kusintha. Kuchigwira msanga kumalepheretsa kuti zinyalala. Kuti mukhale ndi mgwirizano weniweni wa OEM, wogulitsa ayenera kukhala ndi malingaliro awa. Sizokhudza kuyang'anira kusanja mbali zoyipa; ndi za kulamulira ndondomeko kuti mbali zoipa sanapangidwe.
Kuyang'ana zopereka zamakampani omwe adakhazikitsidwa nthawi yayitali, monga mbiri yazaka 30 yomwe idadziwika ku QSY, kuti moyo wautali nthawi zambiri umalankhula ndi kuthekera kosunga mayendedwe amtunduwu. Awona makina awo amchenga akusintha, ukadaulo wawo wakuumba ukutukuka, ndipo ali ndi chidziwitso pazaka zambiri zakutsanuliridwa. Kwa OEM, zomwe zachitika kale ndi chinthu chobisika mukayenerera gawo latsopano. Atha kunena kuti, Kwa geometry yofananira mu chitsulo cha 4340, nayi chinthu chocheperako chomwe tidagwiritsa ntchito, ndipo nayi kumalizidwa komwe tidapeza. Izi zimachepetsa chiopsezo chanu ndi nthawi yachitukuko kwambiri.
Pamapeto pake, wopambana OEM mchenga kuponyera si kugula chinthu. Ndi mgwirizano waukadaulo panjira yolimba, yopanga ndalama. Zimafunika wogulitsa yemwe amawona kupyola nkhungu kuzinthu zonse ndi makina amoyo. Ikadina, imapereka magawo omwe ndi olimba, otsika mtengo, komanso odalirika - ndendende zomwe OEM imafuna.
