Kugadzira a DIY simbi yekukanda fekitori haisi yekudzokorodza chivakwa cheindasitiri mugaraji rako. Izvo ndezvekuvaka inodzokororwa, yakachengeteka, uye scalable maitiro - kutanga nekukandira jecha - iyo inopa anoshanda zvikamu zvaunogona muchina, kuyedza, uye kuvimba. Isu takatungamira vanopfuura makumi matatu nevanomwe vagadziri vedanho rekutanga, maLab ehunyanzvi, uye vagadziri vadiki kuburikidza neshanduko iyi. Vazhinji vanokundikana kwete kubva mukushaikwa kwezvishandiso-asi kubva pakusvetuka nhanho nhatu dzisingagone kutaurirana: kurongeka kwezvinhu, kuongororwa kwekuvimbika kwe mold, uye kupisa kwehuwandu hwekupisa.
Tanga Nezvaunogona Kuyera—Kwete Zvaunotarisira Kuti Zvinoshanda
Vanotanga vanowanzotenga choto chinopisa chakayerwa 1200 ° C uye vanofungidzira kuti inobata aruminiyamu, ndarira, uye grey iron zvakaenzana. Hazvidaro. Aluminium inonyunguduka pa660°C asi inoda kunyatso kudzora kuyerera kudzivirira hydrogen porosity. Simbi ye grey inoda 1250 ° C zvishoma-uye kana choto chako kikanyura pazasi panguva yekudira, simbi inoomesa pakati pegomba. Takamboona mutengi achirasa 14 cylinder head pateni nekuti yavo infrared thermometer inoverenga tembiricha yepasi chete-kwete kunyungudika pool core temp.
Yako yekutanga setup inofanira kusanganisira:
- A calibrated thermocouple probe (Rudzi K, ± 1.5°C kunyatsoita) akaiswa zvakananga musimbi yakanyungudutswa.
- Jecha rakasvibira rinodzorwa nehunyoro (6-7% yemvura nehuremu, yakasimbiswa nedigital mwando mita-kwete bvunzo dzekudzvanya nemaoko)
- Yakamisikidzwa patani dhizaini: 1.5 ° yealuminium, 3 ° yesimbi yakakandwa, hapana kunze
- Mapepa akadhinda akakura kuti aenderane nemaburi emhepo - haana kumbofungidzira
Kanganwa "universal" casting alloys. Tanga neA380 aluminium kana ASTM A48 Kirasi 30 grey iron. Ose ari maviri anopindura achifanofungidzira kune yekutanga gating, feed, uye riser dhizaini. Cobalt-nickel alloys seAMS 5387? Imbomira kusvika wadira 50+ zvikamu zvisina hurema. Kupisa kwavo kupisa ndeye 1/5 iyo yealuminium-saka shrinkage kufanotaura zvikanganiso zvinosanganiswa nekukurumidza.
Jecha Harisi Jecha Rako-Uye Mold Yako Ndiyo Yekutanga Machining Operation
Takaedza majecha masere ekutengeserana munzvimbo nhatu dzine humidity. Maviri chete akaunza simba rakasvibira rinoenderana pamusoro pe140 kPa pa6.2% mwando. Imwe yese yakatsemuka ichizunguzika kana kudonha pakudirwa. Sei? Sodium bentonite yemukati yakasiyana 22-38%. Musiyano iwoyo unoshandura kukiyiwa kwakasimba kwejecha-uye nekuchena kwavanoburitsa kubva patani.
Mold yako haina kumira mushe. Ndicho chikamu chako chekutanga chechokwadi. Pese pese pese pese pese, dhizaini kona, uye mutsara wekutenderana kunovharirwa mukati simbi isati yaibata. Isu tinoshandisa cheki yakapusa: dzvanya chikero chemuchina mujecha rakaporeswa. Kana iyo imprint inobata micheto yakapinza isina kudonha, musanganiswa wako wakagadzirira. Kana ikasvibiswa, wedzera ivhu-kwete imwe mvura.
Zvakare zvakakosha: kuiswa kwemhepo. Kwete chete "kuwedzera mavhavha." Zviise panzvimbo yekupedzisira-yekuzadza * uye* homwe yese inoteya mweya. Imwe winch centre shaft roller yatakakandira mota yeinjiniya yakatadza kuputika kuyedza nekuti imwe 2-mm vent yakavharwa nejecha rakarasika. Air pressure yakavakwa, ndokubva yatsemura ganda rinopisa. Kugadzirisa? Matatu ma 3-mm mamhepo akaboorwa pa 120° intervals akatenderedza hub- akasimbiswa ne compressed air flow test pre-duir.
Nei "DIY Metal Casting Factory" Inoreva Kudzora Kwakasimba-Kwete Zvimwe Zvishandiso
A chokwadi diy simbi yekukanda fekitori inobatanidza kukanda, kugadzira, uye kuongorora-kwete sezvikamu zvakasiyana, asi semhinduro. Unokanda muviri wevharuvhu. Iwe CNC-muchina yayo yekuisa chisimbiso pamusoro. Iwe unoyera flatness pane granite ndiro ine dial indicator. Wobva wagadzirisa kureba kwemuumbi wako ne 0.05 mm kune rimwe batch rinotevera.
Apa ndipo panomira mahobby setups. Vakakanda. Vanoyemura. Ivo havabatanidze kukanganisa kugadzirisa zvinosiyana. Saka isu takavaka pepa rekutevera rakareruka: imwe koramu yekudirwa-choto chevira, nguva yekudurura, mold temp, chiyero chekutonhodza (inoyerwa neIR pfuti pakukanda pamusoro pamakumi matatu-sec intervals), uye yekupedzisira CMM scan kutsauka pamabore akakosha.
Mushure mekudururwa kwe22, mapatani akabuda. Kana mold temp yakadzikira pasi pe28 ° C, shrinkage mupiston pombi yeimba ye42-mm bore yakawedzera 0.018 mm avhareji-yakakwana kubvisa chikamu ichipokana neISO 2768-mK kushivirira. Mhinduro? Preheat molds kusvika 32-35 ° C uchishandisa mwenje wakadzika-wattage kupisa-kwete ovheni. Zvinoenderana, zvinodzoreka, zvinodzokororwa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inoshandisa pfungwa imwechete iyi pachiyero. Nzvimbo yavo inoenderana neISO inobata kukanda kwega kwega senzvimbo yedata - kwete chikamu chete. Dzavo T800 cobalt alloy nozzles dzinoita kuzere zvinhu traceability kubva ingot lot kusvika yekupedzisira X-ray kuongororwa. Chirango ichocho chinotanga chidiki: nyora kudira kwese. Batanidza kukanganisa kwese kune inoyerwa parameter. Rega kufungidzira kuti sei.
Gadzira Sisitimu - Wobva wawedzera Kubuda
Yako yekutanga "fekitori" haitsanangurwe ne square footage kana tonnage. Iyo inotsanangurwa nekudzokororwa: yakafanana dimensional mhedzisiro, yakafanana microstructure, yakafanana pamusoro pekuvimbika-mumabatch. Izvo zvinoda zvinyorwa, kwete zvekushongedza. Gadzira 1-peji yakajairwa maitiro ekushandisa kune yega yega nhanho: kusanganisa jecha, mold ramming, choto chekukwira-kumusoro, kudurura nguva, shakeout hwindo, kutenderera kwekushushikana.
Shandisa zvibatiso zvepasirese. Panzvimbo pekuti “kutonhorera kusvika kwakachengeteka,” nyora kuti “kutonhorera kusvika pasi pakanyorwa kuti ≤120°C papfuti yeIR—yakasimbiswa munzvimbo nhatu.” Panzvimbo pekuti "muchina wekudhinda," tsanangura "kupedzisa kubereka necarbide insert, 0.15 mm radial kudzika, 80 m/min yekucheka kumhanya, mafashama anotonhorera." Precision inobuda kubva kune chaiyo.
Paunorova 95% yekutanga-kupasa goho pamabheji mashanu akateedzana, wawana iyo label. diy simbi yekukanda fekitori. Kwete kare. Kukura kunouya mushure mekudzora-kwete padivi pahwo.
