Anthu ambiri akamamva 'kuponyedwa mchenga kwa mafakitale' amawona njira yauve yopangira zitsulo zolimba. Ndilo lingaliro lolakwika loyamba. Sikuti kungotaya zitsulo m’dzenje la mchenga. Luso lenileni likuwongolera zosintha zomwe wina aliyense amazinyalanyaza - 'mphamvu yobiriwira' ya kusakanikirana kwa mchenga, kutuluka kwa mpweya womwe sungathe kuwona, kutentha kwanyengo panthawi yolimba komwe palibe amene amalankhula m'mabuku onyezimira. Ndawona mapulojekiti ambiri akulephera chifukwa amawona mchenga ngati chidebe chopanda kanthu, osati otenga nawo mbali pantchitoyo.
Maziko: Zonse Ndi Zamchenga (Ndipo Sizili)
Tiyeni tiwongolere izi. 'Mchenga' poponya mchenga wa mafakitale ndi zinthu zopangidwa mwaukadaulo. Mchenga wa silika ndiwofala, zedi, koma binder system ndipamene matsenga kapena masautso amachitika. Dongo lopangidwa ndi dongo (mchenga wobiriwira) ndi wachangu komanso wotchipa pamayendedwe apamwamba kwambiri ngati midadada ya injini, koma panyumba yovuta yapampu yokhala ndi magawo oonda? Mutha kukhala bwino ndi makina opangidwa ndi utomoni monga furan kapena phenolic. Chisankhocho chimalamula chilichonse—kumaliza kwapamwamba, kulondola kwa dimensional, momwe mchenga umagwera mosavuta ukathira kuti usang'ambe. Ndimakumbukira ntchito yapa giya ya m'madzi momwe tinkagwiritsira ntchito mchenga wobiriwira wamba pa mtengo wake. Chotsatira? Kusalekeza kwa mitsempha yamkati pamayendedwe amkati. Tinasinthira ku mchenga wa zircon wokhala ndi chothandizira cha utomoni, vuto linathetsedwa, koma mtengo wa nkhungu udalumpha. Ndiko kusinthanitsa kosalekeza.
Tsatanetsatane wina: kubwezeretsa mchenga. Sikungokhala wobiriwira; ndi zachuma ndi kusasinthasintha. Mchenga wobwezeretsedwa umachita mosiyana. Mbewu zimazungulira, chindapusa chimawunjikana. Ngati simuyang'anira LOI (Kutayika pa Ignition) ndikusintha mwachangu zowonjezera zanu zomangira, mphamvu yanu ya nkhungu imakhala masewera ongoyerekeza. Tinaphunzira izi movutirapo patatha sabata imodzi yopanga nkhungu zowoneka bwino zomwe zimasweka pozigwira. Wolakwa? Mchenga womwe wabwezedwa udakwera kwambiri popanda kusintha kofananira.
Apa ndipamene kukhala ndi bwenzi lodziwa zambiri zakuthupi kumafunika. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi zaka zawo 30 akusewera, adzalandira izi mwamsanga. Amagwira ntchito popanga zipolopolo, ndalama, ndikuponya mchenga, kotero amamvetsetsa zomwe zimatengera mitundu yosiyanasiyana ya nkhungu. Sikuti kungosankha njira; ndizokhudza kudziwa kuti ndi mchenga uti womwe umagwirizana ndi aloyi ndi geometry. Mwachitsanzo, valavu yachitsulo chosapanga dzimbiri yomwe imafuna kukana kwa dzimbiri ingafune utomoni wa furan wa nayitrogeni wocheperako kuti uteteze kutsetsereka kwa pamwamba, momwe sitolo yogulitsira zinthu zonse ingaphonye.
Chitsanzo & Chinyengo cha Kuphweka
Aliyense amaika maganizo pa zitsulo. Chitsanzocho nthawi zambiri chimakhala chotsatira, chomwe ndi cholakwika chachikulu. Popanga mchenga, zinthu zapatani, zolembera, ndi kumaliza ndizofunikira kwambiri. Mapangidwe a matabwa ndi abwino kwa ma prototypes kapena othamanga pang'ono, koma kuti apange mosalekeza, chitsulo kapena epoxy yolimbitsa ndikofunikira. Kuvala ndi kung'ambika pamapangidwe amatabwa kumasintha mobisa pakapita nthawi, ndipo mwadzidzidzi makulidwe a khoma lanu latha.
Ndiye pali draft. Bukuli likuti madigiri 1-3. Zowona ndi zonyansa. Matumba akuya angafunike zambiri. Zowoneka bwino zingafunike zambiri. Poyamba tinali ndi kachidutswa kokongoletsa kamangidwe ka nthiti zowongoka. Zolemba zamabuku zinali zosakwanira; mchenga unkang'ambika nthawi yojambula. Tinayenera kuonjezera zolembera, zomwe zinasintha pang'ono maonekedwe okongola, zomwe zimafuna kukambirana koyambirira ndi kasitomala wotsiriza. Izi ndi zigamulo zowuluka zomwe zimalekanitsa kuponya kogwira ntchito kuchokera ku chinthu chochepa.
Kupanga zitsanzo kumalumikizananso ndi makina. Woyambitsa wabwino amaganizira zamtsogolo. Ngati mukupanga nyumba ya turbine yomwe pambuyo pake idzafunika kutayira bwino kwa CNC, muyenera kusiya ndalama zokwanira komanso zosasinthasintha za katundu pakuponya. Apa ndipamene ntchito yophatikizika imawonetsa mtengo wake. Mwachitsanzo, ku QSY, kuthekera kwawo kwa makina a CNC a m'nyumba kumatanthauza kuti akhoza kuyankha molunjika kuchokera pamakina kupita ku malo ogulitsira: Tikumenya molimba apa pa flange, tifunika kusintha kayesedwe koziziritsa kapena kuwonjezera kuzizira pamapangidwewo. Mayankho otsekeka amenewo ndi fumbi lagolide losasinthasintha.
Kuthira: Chisokonezo Cholamuliridwa
Iyi ndi nthawi ya choonadi. Chemistry yosungunuka iyenera kukhala yolondola-kudetsedwa bwino, kutentha mkati mwa zenera lolimba. Kutentha kwambiri, ndipo mumalowa mumchenga mopitirira muyeso, ndikuwononga pamwamba. Kuzizira kwambiri, ndipo mumapeza mistruns. Koma wamkulu, nthawi zambiri wosalankhula, wakupha ndi chipwirikiti. Mukufuna kudzaza laminar. Mtsinje wosokonekera umalowa mumlengalenga ndi slag, ndikupanga zophatikizika mkati mwa kuponya komwe simungathe kuziwona mpaka zitalephera kuyesa kukakamiza.
Mapangidwe a gating system ndi aluso kwambiri kuposa sayansi. Ndawonapo mitundu yopangidwa mwaluso ya CAD ya zipata ndi zokwera zomwe zidachita bwino kwambiri. Chifukwa chiyani? The kayeseleledwe mapulogalamu ankaganiza zinthu zabwino. Kunena zoona, mchengawo unali wothira madzi, kapena beseni lothira silinali lodzaza. Nthawi ina tidakopera kamangidwe ka mageti kuchokera kugawo lachitsulo chofananira kuti tigwire ntchito ya aloyi ya nickel. Aloyiyo inali ndi mawonekedwe osiyanasiyana a fluidity ndi solidification. Chotsatira chake chinali shrinkage porosity mu malo otentha. Tinayenera kukonzanso chokwera, ndikuchikulitsa ndikuyika manja amphamvu kuti chisungunuke motalika. Zinagwira ntchito, koma linali phunziro la kusachitira zitsulo zonse mofanana.
Gawo ili ndipamene ma aloyi apadera amakuyesani. Zomwe QSY idakumana nazo ndi cobalt ndi ma aloyi opangidwa ndi faifi ndizofunika apa. Ma alloys awa nthawi zambiri amakhala ndi malo osungunuka kwambiri komanso milingo yocheperako yolimba. Amakonda kung'ambika ndi kutentha ngati nkhungu ndi yolimba kwambiri. Kuwonongeka kwa dongosolo lanu lamchenga pambuyo pothira kumakhala kovuta kwambiri monga mphamvu yake musanathire. Ndi kusamalidwa bwino komwe mumangophunzira pogwira zinthu izi mobwerezabwereza.
Shakeout, Kuyeretsa, ndi Mtengo Wobisika
Kuponyedwa kukazizira, kumagwedezeka. Izi zikuwoneka zowongoka. Koma kugwedezeka mwamphamvu kungayambitse kuwonongeka kwamakina pamakina osakhwima. Zipata ndi zokwera ziyenera kuchotsedwa. Kwa zitsulo zokhala ndi aloyi wapamwamba kapena zosapanga dzimbiri, izi nthawi zambiri zimatanthawuza kudula kwa plasma kapena macheka abrasive, osati kungogwetsa nyundo.
Kenako pamabwera kuyeretsa—chinthu chovuta kwambiri komanso chotsika mtengo cha ntchitoyo. Kuphulika kwa mchenga kuchotsa mchenga wopsereza. Kupera kuti mizere yolekanitsa ikhale yosalala komanso kulumikizana ndi ma feeder. Apa ndipamene zowonongeka zapamtunda zimawonekera: kuphatikizika kwa mchenga, mabowo a mpweya, zotsekera ozizira. Mtengo wokonzanso pano ukhoza kupha malire a polojekiti. Njira yopangidwa bwino yokhala ndi mchenga wabwino imachepetsa izi, koma si ziro. Ndakhala masiku ndi chopukusira ndi zida zokonzera zowotcherera ndikuyesera kupulumutsa gulu la zida zomwe zinali ndi zibowo zapansi panthaka, vuto lomwe limabwerera ku mchenga wokhala ndi chinyezi chambiri.
Gawo la post-cast iyi ndichifukwa chake kuyanjana ndi malo omwe ali ndi makina mkati mwanyumba ndi mwayi wabwino. Tengani gawo lomwe latchulidwa Webusayiti ya QSY (https://www.tsingtaocnc.com). Ngati akupanga chopopera chachitsulo chosapanga dzimbiri pogwiritsa ntchito mchenga, amatha kuwusuntha molunjika kumakina awo a CNC kuti ayang'anire flange, kubowola bolt, ndi kumaliza kusindikiza pamwamba. Izi zimachotsa mayendedwe, zimagwira ntchito mosamalitsa (amadziwa zofooka zake), ndikuwonetsetsa kuti malipiro a makina amalemekezedwa. Kubwereza kobwerezabwereza ndi pompopompo.
Pamene Kuponya Mchenga Ndi (Ndipo Si) Yankho
Kuponyera mchenga wa mafakitale kumapambana pazigawo zapakati mpaka zazikulu, zapakati mpaka zazikulu, pomwe geometry imakhala yotseguka komanso zovuta zamkati zimayendetsedwa ndi ma cores. Ndizosangalatsa kwambiri pamakina olemetsa, matupi akulu a valve, nyumba zamapampu. Zida zake (chitsanzo) mtengo wake ndi wotsika kuposa nkhungu yosatha kapena kufa, zomwe zimapangitsa kuti zikhale zogwira ntchito zazifupi.
Koma si yankho pa chilichonse. Ngati mukufuna malo osalala kwambiri, zolimba ngati zotayira pansi pa IT13, kapena makoma owonda kwambiri (pansi pa 3mm pazitsulo zachitsulo), mukukankhira motsutsana ndi chilengedwe chake. Ndipamene mumayang'ana kuyika kwa chipolopolo (kumaliza bwino, kwapakati pazovuta) kapena kupanga ndalama (kwa mawonekedwe ovuta, kumaliza kwabwino kwambiri). Wothandizira bwino samangogulitsa njira imodzi. Ayenera kukulangizani. Kuyang'ana mbiri ya QSY, yomwe imatenga zipolopolo, ndalama, ndi kuponya mchenga, ali ndi mwayi woyimba foniyo moyenera. Anganene kuti kuponyedwa mchenga kwa giya yayikulu, yokulirapo yopanda kanthu koma kukutsogolerani kuzinthu zopangira ndalama zopangira choyikapo nyali chopindika chokhala ndi masamba opindika.
Zotengera zenizeni? Kuponyera mchenga m'mafakitale ndi njira yozama kwambiri, yolemera mosiyanasiyana yomwe ikuwoneka ngati yosavuta. Kupambana kwagona pakulemekeza mchenga, kuchita bwino patani, kuwongolera kuthirira, ndikukhala ndi njira yomveka bwino yokonza pambuyo poponya. Izo siziri zachikale; ndi chida chofunikira kwambiri chomwe, chikagwiritsidwa ntchito mwanzeru komanso chidziwitso chakuya, chimapanga zigawo zamphamvu kwambiri komanso zotsika mtengo. Mashopu omwe akuyenda bwino ndi omwe amawona unyolo wonse, kuyambira mulu wamchenga mpaka gawo lomalizidwa lopangidwa ndi makina, ngati njira imodzi yolumikizirana. Ndiko kusiyana pakati pa kupanga kuponya ndi kupanga chigawo chodalirika.
