Paunonzwa 'chaizvo chekudyara kukanda', iwo mufananidzo wepakarepo kazhinji weasina kukanganisa, net-shape aerospace zvikamu. Ndiyo yakanakisa yekushambadzira. Chokwadi chiri pasi, mushure memakumi matatu emakore mumutambo uyu, inhaurirano yenguva dzose pakati peiyo yakanaka uye yakasindimara fizikisi yesimbi yakanyungudutswa uye magomba eceramic. Vatengi vazhinji, kunyanya avo vatsva muchiitiko ichi, vanouya nemhando dzeCAD vachitarisira zvishamiso-kushivirira kwedimensional kusimba kupfuura tsiye yegota, se-cast-surface inopedza kukwikwidzana, uye zvese nemutengo weyuniti unokodzera kudhindwa kwakagadzirwa-zhinji. Ndiyo hurukuro yekutanga yatinayo paQSY: kuseta tarisiro kunharaunda yezvinogoneka mumuviri. Hunyanzvi hwechokwadi haungori mukugadzira; zviri muhuinjiniya cheni yese-kubva papateni yewakisi kusvika pachikamu chakagadzirwa nemuchina-kurova nzvimbo inotapira pakati pekuita, mutengo, uye kuvimbika. Chirango chekuvamba, kwete mashiripiti.
Iyo Yakanyanya Kusanzwisisa: Kurongeka Kunoreva Hapana Basa Mushure mekukanda
Ngative vakagomara. Kana chikamu chakanyatso kuomarara, chine mukati menzira, undercuts, kana madziro matete, precision investment casting isingakundiki kugadzira. Asi 'as-cast' inenge isati yambo 'kugadzirira-kuisa'. Iyo chaiyo inoreva kudzokororwa uye kutorwa kweruzivo, kwete yekupedzisira dimensional certification. Ndakaona kukanda kwakanaka kweturbine blade kutadza kutariswa nekuti bhegi rekukwira rakadzimwa nezvikamu zvitatu kubva mugumi zvemirimita. Majekiseni ewakisi aipfekwa, zvishoma. Ndosaka isu takabatanidza CNC machining mukati-mumba makumi emakore apfuura. Iko kukanda kunokuwana iwe 95% ipapo, mune chaiyo geometry, nekuvimbika kwezvinhu. Iyo CNC inopedza machining, kazhinji pamichina 5-axis, inokuwana iwe yekupedzisira, yakasimbiswa zviyero. Kufunga nezve kukanda uye kugadzira seakasiyana vatengesi matanho ndiko uko mapurojekiti anorasikirwa nenguva, mari, uye kuunza kushivirira kurongedza-up zvikanganiso.
Kusarudzwa kwezvinhu ndiyo imwe hafu yeizvi. Tinoshanda zvakanyanya ne simbi isina tsvina uye nickel-based alloys. Gomba rakajairwa kutsanangura alloy-inoshanda senge Inconel 718 kune yakakwira-tembiricha zvivakwa, asi isingaverengere kuderera kwayo kwakanyanya uye kupisa kubvarura tsika panguva yekusimba. Iyo pateni negoko dhizaini ye718 yakasiyana zvakanyanya pane ye316 isina tsvina. Iwe haugone kungochinjanisa izvo zviri muiyo spec sheet uye kutarisira iwo maitiro akafanana kushanda. Takadzidza izvi nenzira yakaoma kare nebhechi remapombi epombi akatsemuka zvisingaonekwe mugoko. Mhinduro yacho yaive musanganiswa weakasarudzika gating kudzora kusimba kwekutungamira uye tweak kune goko rekubheka kutenderera. Aya ndiwo mabikirwo akasarudzika, akavakwa anopfuura makore makumi matatu, anoparadzanisa chitoro chebasa kubva kune nyanzvi.
Izvo zvinondiunza kune inoshanda pfungwa nezve shells. Iyo 'shell mold casting' maitiro atinoshandisa-kuvaka iwo maceramic layers-ndimo munogara akawanda emhizha. Yakanyanya kutetepa goko, uye iwe unowana kubhuroka, kukanganisa uye nengozi kukundikana. Yakanyanya kukora, uye unorasikirwa nedimensional kurongeka sezvo goko rikasadonha kure nesimbi iri kupera zvakanaka. The slurry viscosity, stucco jecha saizi yezviyo, nguva yekuomeswa pakati pemajasi… hunyanzvi hwekunzwa sekunge hwesainzi. Nyanzvi ine ruzivo rwokuzviwanira inogona kuona nokunzwika kwokurovera goko rakaomeswa kana zvakanaka kuenda. Ichi hachisi chinhu chaunozvigadzirisa zvachose.
Iko Kunopenya Kwacho (Uye Kwaisingaite)
Iko kuhwina kwekirasi kwekudyara kwekudyara kwakaoma-kune-huremu. Aerospace mabhureki, zvekurapa chiridzwa zvikamu, fluid inobata zvikamu zvine akakosha manifolds. Isu nguva pfupi yadarika takamhanyisa purojekiti yeimba ye sensor yaifanirwa kunge iri hermetic, mu17-4PH isina tsvina, ine mabheti emukati uye ekunze anokwira tambo. Kukandira kwakabvumira maitiro emukati kuti aumbe, kuchengetedza huwandu hukuru hweEDM kana welding basa. Isu takabva taita CNC-machini zviso zvekuisa chisimbiso uye shinda kuti titaure. Imwe nzira inoyerera, imwe yehutano system. Kuedza kugadzira izvo kubva kubillet kungadai kwakadhura zvakanyanya.
Asi hazvisi zvezvose. Ini ndinogara ndichiyambira kusaishandisa kune akareruka, chunky geometries. Chivharo chakasimba kana basic flange? Iwe uri nani nekukanda jecha kana kutotanga kubva kubhawa stock uye machining. Mutengo wewakisi pateni uye goko unoderedzwa pamusoro pekumhanya, saka kune prototypes kana yakaderera mavhoriyamu, mutengo weyuniti wakakwira. Iyo breakeven point inoenderana nedhizaini. Dzimwe nguva, kukosha hakusi mumutengo chaiwo asi mukuderedza nguva yekubvisa nekubvisa matanho egungano.
Iyo Yekubatanidza Edge: Kubva kuCAD kuenda kuCrate
Izvi ndizvo zvakavakwa kuseta kwedu kuQingdao Qiangsenyuan Technology Co., Ltd. (QSY) kwakatenderedza. Kubatanidza kwakatwasuka harisi izwi rekutaura; chinhu chinodiwa pakutonga. Kana mutengi achititumira modhi yemuviri wevharuvhu, timu yedu yeinjiniya haingotarise chikamu. Isu tinogadzira musangano wewakisi (kuti zvikamu zvakawanda zvakabatanidzwa sei pa'muti'), tevedzera kuzadza mold uye kusimba kufanotaura shrinkage porosity, uye tozoronga iyo CNC machining kubata pane imwecheteyo dhijitari modhi. Iyi injiniya yekumberi-yakatakura yakakosha. Kukandira kwakanyatsogadzirwa kunoderedza huwandu hwesimbi inozogadzirwa pave paya, zvichichengetedza kupfeka kwezvishandiso uye mutengo wezvinhu, kunyanya pakudhura. cobalt-based alloys.
Ndinoyeuka kukundikana kwakatidzidzisa chidzidzo ichi zvachose. Mutengi aisimbirira kushandisa ega jekiseni rewakisi kune akatevedzana ekuisa marine. Chishandiso chaive chekare, maitiro ewakisi aive nekusiyana kudiki. Takaakanda, tikaagadzira, tichibva tawana mutsauko webatch-to-batch mukukora kwemadziro izvo zvakaita kuti vamwe vatadze kuyedzwa kwekumanikidza. Dambudziko rakatanga muwakisi, yakakwidziridzwa mugoko, uye yaisakwanisika kugadzirisa mukugadzira. Kubva ipapo, isu tinoda kudzora, kana kuomarara kuongorora, iyo ketani yese. Webhusaiti yedu, tsngtaocnc.com, inotsanangura kugona uku, asi humbowo chaihwo huri mumishumo yekutanga yekuongorora yatinogadzira.
Rutivi rwekugadzira hausi kungowedzera. Kugadzira nzvimbo yekukanda kwakasiyana pane kugadzira billet rakagadzirwa. Ganda rinogona kuve nekuoma kushoma kusiyanisa, uye kugadzirisa kunofanirwa kuzvidavirira kune dzimwe nguva-zvisina kujairika kukanda datum nzvimbo. Vana machinists vakazvijaira izvi. Ivo vanoziva kutora kwekutanga kuchekwa kumisa datum yechokwadi kubva kune 'as-cast' chikamu, inova hunyanzvi pachayo.
Material Nuances: Haisi Ingori Nhamba Yegiredhi
Kushanda neakakosha alloys kunoreva kunzwisisa maitiro avo kunze kwe data sheet. Tora nickel-based alloy yekushanda kwepamusoro-tembiricha. Yayo yekukanda maparameter ikutamba kwakasimba. Dururira zvakanyanya kupisa, iwe unowana yakawandisa zviyo kukura uye slag maitiro. Dururira zvakanyanya, iwe unowana mistruns. Iyo post-casting heat treatment iriwo chikamu chekukanda, kwete danho rakasiyana. Kune kunaya-kuomesa mamakisi, iyo mhinduro yekurapa uye kuchembera kutenderera kunofanirwa kuvandudzwa tandem nedhizaini yekukanda kuti uwane yakatsanangurwa michina zvivakwa muchikamu chose, kwete chete pabvunzo kuponi.
