Vanhu vazhinji pavanonzwa kambani yekukanda wakisi yakarasika, vanofananidzira rima, rine huruva rinogadzira tunhu tudiki. Ndiyo yekutanga kusanzwisisa. Chokwadi inyanzvi yehunyanzvi, kazhinji inoodza mwoyo, uye ine mubairo wakadzama wekushandura wakisi isina kusimba pateni kuita chinhu chakasimba, chepamusoro-soro chesimbi. Hazvisi zvekungogadzira zvinhu; ndezvekugadzirisa matambudziko ejometri, zvinhu, uye mutengo usingagone kubata mamwe maitiro.
Iyo Core Haisi Wax, Ndiyo Shell
Munhu wese anogadzirisa pawakisi. Chokwadi, iyo pateni yakakosha, asi iwo mashiripiti chaiwo-uye uko zvitoro zvakawanda zvinoratidzira mettle yavo-iri muchivakwa checeramic shell. Apa ndipo panofarira kambani Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) inozviparadzanisa. Hakusi kushanda kwe dip-and-dunk. Kutenderera kunodzorwa, kwemazuva mazhinji ekunyika sumbu rewakisi muslurry, kurinamira nejecha refractory, nekuomesa. Dzokorora. Kanomwe, sere, dzimwe nguva kapfumbamwe. Ukobvu, nharaunda yekuomesa (mwando muvengi), granularity ye stucco - imwe neimwe nhanho isarudzo inokanganisa yekupedzisira kwepasi uye kugadzikana kwedimensional. Ita zvisizvo, uye iwe unowana goko rinotsemuka panguva ye dewaxing (kazhinji mune autoclave) kana, zvakanyanya, panguva yekudira.
Ndinorangarira basa repombi yepombi, yakaoma, yakatetepa-vaned dhizaini mu316 isina tsvina. Wakisi yakanga yakakwana. Matanho mashoma ekutanga emateko aive mabhuku ekuverenga. Takabva tarova humid spell. Chikwata chakasundidzira kuchengeta kurongeka, kunyura iyo yapfuura layer isati yaoma zvakazara. Zvakaguma nei? Deko rakanaka iro, pakupfurwa, rakagadzira mitsetse yebvudzi. Simbi yakanyungudutswa yakapinda, ichigadzira zvimbi pamavhane izvo zvaisaita kubvisa pasina kukanganisa chimiro. Kurasikirwa zvachose. Kukundikana ikoko chaive chidzidzo chehutsinye mukuremekedza maitiro pakarenda. Icho chidzidzo chakadzika mukushanda kwakatora makumi emakore, seQSY's 30-year track rekodhi. Iwe haugone kumhanyisa ceramics.
Iri goko, kana rangodzingwa, rinova monolithic, yakasununguka mold. Ndiko kubatsirwa kwakakosha. Hapana mitsara yekuparadzanisa, hapana makona ekunyora. Iyo inobvumira iwo anopenga geometries- emukati mavhesi, undercuts, organic maumbirwo-ayo anogoneka chete nemutengo wakanyanya uye kuoma. Goko inzvimbo isina kunaka inotsanangura kugona kwechikamu.
Material ndipo panochinja Mutambo
Kurasika kukanda wakisi hakusiri kwezvidhori zvebhuronzi chete. The material spectrum yakakura, uye kusarudzwa kunoraira zvese kubva pakudurura tembiricha kusvika kune post-casting heat treatment. Iyi ndiyo imwe nzvimbo iyo ruzivo rusingagone kutaurirana. Kushanda nekabhoni simbi chinhu chimwe; kudira nickel-based alloys kana cobalt-based alloys imhuka yakasiyana zvachose.
Aya ma superalloys ane mapoinzi ekunyungudika uye anowanzo shanda. Vanoda kuumbwa kwegomba chairo kudzivirira kusangana kwekemikari pakudziya kwakanyanya. Iyo gating system - migero inodyisa simbi mugomba rekuumbwa - inofanirwa kugadzirwa zvakasiyana. Iwe unoda zvigadziko zvakakura zvesprue uye mamwe magedhi ane hunyanzvi kuti uve nechokwadi chekudyisa uye kuderedza shrinkage porosity mune izvi zvinodhura zvinhu. Iyo generic gating dhizaini inorasa iyo $10,000 batch yeInconel mumaminitsi.
Kutarisa pane zvinyorwa zvemutengesi zvinokuudza zvakawanda. Paunoona kambani yakanyorwa kwete chete simbi isina tsvina uye simbi yakakandwa, asi kunyanya kudaidza alloys akakosha, inoratidza chivakwa chakagadzirirwa basa repamusoro. Zvinoreva kuti vane ruzivo rwemetallurgical uye tekinoroji yevira yekuibata. Ibheji rakanyarara rekugona. Nhanganyaya pfupi yesaiti yeQSY (tsngtaocnc.com) inowana izvi zvakanaka-inotungamira nemagadzirirwo asi pakarepo inoamisa mumidziyo, kusanganisira iwo akakosha alloys. Ndiyo pfupiso yemurapi.
Iyo Isingadzivisike Muchato: Kukandira uye CNC
Heino chokwadi chakaoma: hapana mari yekukanda inobuda yakakwana. Pane nguva dzose kuchenesa. Kupenya pamagedhi ekubatanidza, madiki epamusoro nodules kubva kune shell texture. Kune bhuraketi iri nyore, vhiri rekukuya rinogona kukwana. Asi kune chaiyo valve muviri kana turbine chikamu, unoda machining. Ichi ndicho chikonzero vanokwanisa zvikuru makambani ekukanda wakisi akarasika hazvisi zvekutanga; iwo akabatanidzwa ekugadzira zvikamu.
Kuve neCNC machining mumba haisi nyore; chinhu chinodiwa pakutonga. Iwo machinists uye mainjiniya ekutanga vanofanirwa kutaura. Iye mukomana ari kuronga iyo CNC anofanirwa kunzwisisa iyo yekukanda ingangoita shrinkage uye inogona kukanganisa nzvimbo yekumisikidza iyo chaiyo datum maficha. Ndakaona zvikamu zvichiraswa mukugadzira nekuti kukanda kwacho kwaive kwakaringana kune wakisi pateni, asi iyo pateni pachayo haina kugadzirwa ine yekupedzisira machining stock mupfungwa. Yakanga iri kutadza kwekugadzira kwakazvarwa kubva kune siled process.
Kubatanidzwa uku ndiko kunoreva chaizvo izwi rekuti precision investment casting. Ndiyo loop kubva ku mold dhizaini kusvika pakukandira kune yekupedzisira machining kusvika pakuongorora. Kambani inopa ese ari maviri shell mold casting (a cousin process, kazhinji yezvikamu zvakakura) uye yakazara CNC machining pasi pedenga rimwe, sezvakaratidzwa muQSY's scope yekushanda, iri kuzvigadzirisa kugadzirisa dambudziko rose, kwete chidimbu chayo. Vanogona kutora mutoro wekuunza chikamu chakapedzwa, chinoshanda, kwete kungokanda kwakashata.
Dhiyabhorosi mune Details: Gating uye Kubereka
Kubatsira pakukandira wakisi kunorarama uye kunofa negoho. Uye goho rinonyanya kutsanangurwa muimba yewakisi, panguva yekuungana kwemuti. Apa ndipo panosangana hunyanzvi hwezvehupfumi. Uri kusonerera wakisi mapatani pane pakati wakisi sprue. Iwe unogona kukwana zvikamu zvingani? Unodzifambisa sei kuti ive nechokwadi chekuyerera kwesimbi nekudyisa? Sendimita imwe neimwe yemuti iwoyo isimbi inonyungudutswa, yodirwa, uye gare gare kutemwa uye kunyungudutswa.
Kusashanda kwemuti kugadzira kunouraya margin yako. Pamusoro-gedhi chikamu, uye iwe unoparadza simbi uye kuwedzera machining mutengo. Pasi-gedhi iro, uye iwe unowana shrinkage cavities, uchikwenya chikamu zvachose. Iyo inogara iri optimization puzzle. Iwo akanakisa maitiro mainjiniya ane raibhurari yemifananidzo yepfungwa-ichi chimiro chinoda gedhi repamusoro, ichi chinoda kuzadzwa kwepasi, ichi chikamu chakakora chinoda kutonhora kudzora kusimba. Pane software yeiyi izvozvi, asi iyo intuition yekuona zviuru zvekudururwa haidzoreki.
Uyu mutyairi wemutengo wakavanzika vazhinji vatengi havakoshese. Ivo vanoona mutengo wega-wega asi kwete maawa einjiniya anopedzerwa pakuenzanisa uye nemiedzo yemuviri kuti vawane gedhi rakakodzera rechikamu chitsva. Iyo yakanaka yekutanga ichave iri kumberi nezve ichi chikamu chebudiriro. Haisi imwe mari yekuwedzera; ibasa rekutanga rinoita kuti kugadzirwa kwakagadzikana, kwepamusoro-soro kuitwe gare gare.
Saka, Chii Chauri Kunyatsotsvaga?
Paunenge uchiongorora a kambani yekukanda wakisi yakarasika, hausi kutenga chinhu. Uri kutsvaga wekushamwaridzana naye. Webhusaiti, pepa rekutengesa - zvinongori zviratidzo. Iwe unofanirwa kuchera mukati mekutonga kwemaitiro. Bvunza nezve yavo shell room climate control. Bvunza kuti vanogadzira sei magedhi eiyo alloy nyowani. Bvunza kuti uone mienzaniso yemabatiro avanoita machining datum pane as-cast surfaces.
Muedzo chaiwo uri pakuti vanotaura sei nezvekukundikana. Vane nyaya dzezvinhu zvisina kumira zvakanaka uye zvavakadzidza here? Chero chitoro chinoti 100% budiriro iri kunyepa kana kuti haina kusunda envelope. Iwo akakosha, ayo ane makore makumi matatu enhoroondo sechikwata chiri kumashure kweQingdao Qiangsenyuan, ane mavanga uye anotevera maitiro tweaks kuratidza kuti vanga vari mumigero. Hupenyu hwavo hurefu pachahwo inzvimbo yedata.
Pakupedzisira, zvinosvika pakuvimba mukurangwa kwavo. Vanogona here kushandura nguva dzose chinangwa chako chekugadzira-chingave chiri nyore simbi bracket kana yakaoma Investment casting mumoneri—kuva chinhu chakavimbika, chine ruzha? Ndiwo mubvunzo chete une basa. Zvimwe zvacho zvinongova wakisi uye ceramic.
