Paunonzwa 'high precision magnesium alloy die casting', mufananidzo wepakarepo unowanzo kunge usina kukanganisa, nhete-madziro, yakaoma chikamu chakananga kunze kwekufa, chagadzirira kuungana. Ndiyo yakanakisa yekushambadzira. Chokwadi, icho chatinonetsana nacho zuva nezuva, ndechekuti kuwana chokwadi chepamusoro muMg alloys ishoma nezve alloy pachayo uye nezve kudzora zvese zvinoitika simbi isati yatombobata mhango yekufa. Ndiyo hurongwa, kwete imwe nzira. Vazhinji vatengi vanouya vachifunga kuti mashiripiti ari mu magnesium alloy formula-AZ91D vs. AM60B- uye zvisinei izvo zvine basa, ndingapokana dhizaini yegedhi, kutonga kwekupisa kwekufa, uye maparamendi ekupfurwa anowanzo gadzira kana kutyora stack yekushivirira tisati tatombotaura nezvechipiri. CNC machining.
Nheyo: Sei Magnesium, uye Nei Iine Mano
Isu tinoshanda nezvinhu zvakawanda paQSY-isina, nickel-based alloys yenzvimbo dzakanyanyisa-asi. magnesium alloy die casting inotora niche yakasarudzika. Chikumbiro chiri pachena: simba rinoshamisa-ku-kurema, kunyorova kwakanaka, machinability akanakisa. Asi mukurumbira wayo wekuve 'nyore' kukanda unorasisa. Hongu, inoyerera semvura ichienzaniswa nealuminium, ichizadza zvikamu zvitete zvinoyevedza. Ndiko kukwidza. Iyo yakashata ndeyekuyerera kwakafanana kunoita kuti iite mhirizhonga yekuzadza kana iyo yekupfura system isina kunyatso kurongeka, zvichitungamira kune mhepo kuvharirwa uye porosity chaipo pausingade - munzvimbo dzakatemerwa. high nemazvo kugadzira gare gare. Iwe haugone kugadzira muchina mupore.
Ini ndinorangarira chirongwa che sensor pekugara makore mashoma kumashure. Chikamu chacho chaive ne0.05mm kushivirira pane yakaoma bore. Takashandisa premium alloy, asi mapfuti ekutanga akatadza kuongororwa. Nyaya yakanga isiri iyo alloy kuchena; kwaiva kufa kusawirirana kwekushisa. Imwe hafu yekufa yaimhanya 30 ° C inotonhorera kupfuura imwe, zvichikonzera kusaenzana kusimba uye warpage iyo yakauraya iyo chaiyo. Isu taifanira kudzoreredza mamwe mitsara yekutonhodza uye kuenda ne pulsed kutonhora regime. Ndirwo rudzi rwemaoko-pakugadzirisa izwi rekuti 'high precision' inoda chinyararire.
Apa ndipo pane kwatakabva shell mold casting uye Investment casting kune mamwe masimbi anozivisa yedu Mg kufa casting basa. Aya maitiro ndeezvekungwarira kupisa uye gating kutonga kuti uwane kugadzikana kwedimensional. Isu tinoshandisa ihwo huzivi hwekudzora nzira yekusimbisa, panguva inokurumidza kutenderera nguva. Ipfungwa.
Iyo Die ndiyo Gamba Risina Kusungwa (kana kuti villain)
Kana uchida high precision magnesium alloy die casting, tanga nekudyara 60% yekuedza kwako uye bhajeti mudhizaini yekufa uye kuvaka. Kufa kwakanaka kweMg hakusi kungoita simbi yakaoma. Iyo thermal gradient manejimendi yakakosha. Isu tinowanzo shandisa conformal kutonhora chiteshi padhuze neakakosha maficha izvozvi, chimwe chinhu chatakadzidza chaive chisingagone kutaurirana kune dzakasimba-kushivirira zvikamu. Iyo inofa simbi giredhi ine basa zvakare-H13 yakajairwa, asi kune-refu-inomhanya, yakakwirira-chaiyo mabasa, giredhi rekutanga rine zvirinani kupisa kupera simba kuramba rinobhadhara nekuchengetedza magonhi pamusoro pezviuru zvematenderedzwa.
Venting ndehumwe hunyanzvi husina kujeka. Mg inoda mhepo ine hukasha kupfuura aluminium nekuda kwekukurumidza kuzadza, asi mavhavha anofanirwa kuiswa uye nehukuru kudzivirira kupenya uku uchirega mweya kutiza. Nguva zhinji, ndakaona kufa uko mavhavha aive efungidziro, zvichitungamira mukutsva-mukati megasi homwe dzinoita senge hurema hwepamusoro uye dzinoparadza high nemazvo pamusoro pekupedzisira zvinodiwa. Iyo chiyero pakati pekumhanya kwekuzadza uye kunyatsoita mhepo iyo iwe unongodzidza nekupfura akawanda ezvakaipa zvikamu kutanga.
Takabatana nechitoro chekushandisa pane inofa yechinhu chakareruka che drone. Dhizaini yekutanga yaive nemabhuku ealuminium masuwo. Isu takasundira kumashure, tichisimbirira pane fan gedhi system ine yakapinza yekufashukira zano kune yaMg yekuyerera maitiro. Mushopu wezvokushandisa wakanga usina chokwadi—wakanga wakaoma zvikuru kugadzira muchina. Asi yekutanga-kupfura goho pazvikamu zvakanaka zvakasvetuka ne40%. Ndiro rinoshanda, risiri-rinoyevedza basa kuseri kwekiyi kiyi.
Machining: Iko Kunozonyatso onekwa
Apa ndipo panopenya nzira yeQSY yakabatanidzwa. Kwete high precision magnesium alloy die casting nzira inopera pasina kufunga machining. Kukandira kunokuwana 95% ipapo; CNC machining inokiya mune yekupedzisira 5% yechokwadi. Asi machining Mg imhuka yakasiyana. Izvo hazvina kuita sekugadzira masimbi asina tsvina kana nickel-based alloys isu tinobatawo. Mg machipisi anogona kupisa moto, saka inotonhorera kusarudzwa uye chip evacuation ndiko kuchengetedza-kwakakosha. Iwe zvakare haugone kushandisa iwo akafanana ekugadzirisa anomanikidza-Mg yakapfava, saka iwe unozokanganisa chikamu kana iwe ukasunga zvakanyanya, uchikanda zvese zvekukanda kunze nepahwindo.
Isu tinogadzira zvigadziriso zvekukanda uye machining zvigadziriso tandem. Isu tinogona kuwedzera madiki, ekuzvipira ekutsvaga mapedhi pane yekukanda yakanangana neiyo CNC vise kuti ibate, iyo inonyungudutswa mukushanda kwekupedzisira. Izvi zvinovimbisa kuti chikamu chinoratidzwa kubva kune chayo datums, isina kukanganiswa nechisimba chekumanikidza. Iyo inhanho yekuwedzera, asi ndiyo chete nzira yekurova nekuvimbika izvo ± 0.025mm kushivirira paimba yakatetepa-yakavakirwa.
Kukundikana kwatakadzidza kubva: takambogadzira batch yeAZ91D zvikamu zvakaoma kuti zvipere zvirinani. Kupisa kwekupisa kubva mukugadzira, kusanganiswa neguruva rakanaka, kwakagadzira njodzi yekupotsa moto. Ikozvino, isu tinoshandisa chaiyo yakakwira-vhoriyamu, yakaderera-kudzvanya inotonhorera inodzora kupisa uye inodzvanya guruva pasina kukonzeresa ngura pamusoro pemichina. Chidzidzo chakadzidza nenzira yakaoma.
Material Nuances Kupfuura Data Sheet
AZ91D ndiyo bhiza rekushanda, asi rekuda chaizvo high nemazvo maapplication, kunyanya painoda kuramba kana tembiricha yepamusoro inodiwa, tinotarisa alloys seAE44 kana kunyange tsika tweaks. Chinokosha kutaurirana nemutengi nezvemamiriro ekushanda chaiwo. Imba yakamira here kana kuti chikamu chinofamba chiri pasi pemutoro? Ichaona bhasikoro rinopisa here? Mhinduro dzinoshandura kurudziro yealloy uye, nekudaro, magadzirisiro atinoita yekukanda kufa uye kupisa kupisa paramita.
Semuenzaniso, mamwe maalloys anowanzo kutarisana ne micro-porosity pasi pemamwe mazinga ekusimba. Izvi zvingasaratidzike paX-ray asi zvinozokonzeresa kupedzwa kwepamusoro panguva yekukwenenzverwa kana nhanho yekupotera gare gare, zvichikanganisa kunaka kwe 'chaiyo'. Isu takatanga kushandisa chaiyo-nguva yekutarisisa pamichina yedu yekukanda zvine hukasha, kuteedzera paramita senge kusimbaradza kudzvanywa uye kunonoka-kupfura kumhanya kunopesana negoridhe sampuli mbiri. Zviri pamusoro pekugadzira siginecha inodzokororwa kune imwe neimwe chikamu nhamba, kwete kungomhanya kune yakajairwa muchina kuseta.
Iyi nhanho yekutonga ndiyo inovhara ruzivo rwedu mukati Investment casting ye superalloys - uko kudzokororwa kwemaitiro chitendero - kune yakakwirira-vhoriyamu yenyika yeMg die casting. Misimboti yemetallurgical control inotamiswa.
Iyo Integrated Supply Chain Reality
Pakupedzisira, kuwana yakavimbika high precision magnesium alloy die casting hachisi chiito chega. Zvinoda chiuno chakasimba nevashambadziri vezvigadzirwa, vanofa vanogadzira, uye post-processing vadyidzani. PaQSY, kuve nekukanda uye CNC machining pasi pedenga rimwe, sezvinoonekwa mukushanda kwedu kuQingdao Qiangsenyuan Technology Co., Ltd.https://www.tsingtaocnc.com), inobvisa chitubu chikuru chekusiyana. Iko hakuna mhosva yemutambo pakati peimba yekukanda uye chitoro chemuchina kana kushivirira kukapotswa. Chikwata chinokandira chikamu ndicho chimwechete chinochigadzira, saka loop yemhinduro inoitika ipapo ipapo.
Isu tinokwanisa kuteedzera kusaenderana kumashure kune yakatarwa nhamba yepfuti, tarisa maparamita emuchina kubva kubhechi iro, uye gadzirisa. Kubatanidzwa kwakatwasuka uku, kwakakwidziridzwa mumakore edu makumi matatu mukukandira uye kugadzira, kune nharo ndiko kukuru kugonesa kwe 'kurongeka kwepamusoro'. Iyo inoishandura kubva kune tariro yakatarwa kuita inodzoreka, zuva nezuva kubuda.
Saka, kana mutengi achiuya kwatiri nedhirowa izere nekushivirira kwakasimba uye obvunza kana isu tichiita 'yakanyanya chaiyo magnesium die casting', mhinduro yangu ndeye nguva dzose, Tinogona, asi ngatitaure nezve chikamu chako chese chehupenyu, kubva padhizaini yekufa kusvika pakuongorora kwekupedzisira. Nekuti kuita kwayo hakuitwe nechinguva chimwe; inovakwa kuburikidza neketani yezvisarudzo zvemaune, zvinodzorwa, uye kazhinji zvisina kunaka. Ndiyo nyaya chaiyo kuseri kwekiyi.
