Ngatitaure nezve prototype jecha kukanda. Ndiyo imwe yeaya mazwi anokandwa kwakawanda, kazhinji nekamwe kusanzwisisana. Vanhu vanonzwa prototype uye vanofunga nezve 3D kudhinda kana yakakwirira-kumhanya machining, chimwe chinhu chakapfava uye chedhijitari. Vanobva vanzwa jecha richikanda uye mufananidzo mukuru, kugadzirwa kwakashata kunomhanya kumabhuroko einjini. Iwo mashiripiti chaiwo, uye dambudziko chairo, rinoitika ipapo panosangana pfungwa mbiri idzi. Hazvisi zvekugadzira chidimbu chimwe chakakwana murabhoritari; ndezvekugadzira chikamu chinoshanda, chinoyedzwa chinoita senge shanduro yekupedzisira yekugadzira ichaita, uchishandisa iyo imwechete yakakosha mhuri yemaitiro. Chinangwa hachingori chimiro - chimiro chemumiriri, maekiseni ekunyora, kupera kwepamusoro, uye zvese zvinokonzeresa zvinobva mukudurura simbi mujecha mold. Nguva zhinji ndakaona mapurojekiti achimira nekuti prototype yakagadzirwa kubva kune imwe nzira zvachose, uye data kubva mukuyedzwa haina kushandura. Ndiyo gap prototype jecha kukanda chinangwa kubhiriji.
Iyo Core Idea: Kuvimbika Pamusoro pePolish
Iko kukosha kwekushandisa jecha kukanda kune prototype kuvimbika. Uri kuzvipira kune chokwadi chegadziriro yacho kare. Kana chikamu chako chekupedzisira chiri kukanda jecha, saka prototype yako inofanirawo kuva. Izvi zvinomanikidza dhizaini yekugadzira (DFM) nhaurirano kuti dziitike pakutanga, kwete sekufunga kwazvino. Iwe uchaona kwaunoda dhizaini, iwe uchanzwa huremu hwesimbi, iwe unonzwisisa gating uye kusimuka matambudziko pachako. Mudzidzisi ane hutsinye asi akatendeseka. Iyo yakanaka machined billet prototype inogona kutaridzika yakakwana padhesiki, asi haina chainokuudza nezvekuti simbi ichayerera sei muforoma, uko shrinkage porosity inogona kuitika, kana kana madziro ako makubvu shanduko akanyanya kuomarara kune yekutanga maitiro.
Ndinoyeuka purojekiti yebhuraketi rinokwirisa rechidimbu chemidziyo yemuindasitiri. Yekutanga prototype yemutengi yaive CNC yakagadzirwa kubva yakasimba aluminium ndiro. Yakakwana, yakashanda. Ivo vanovhenekera chishandiso chekukanda-kudzvanya kufa. Mapfuti ekutanga kubva mukugadzira kufa aive akazara neinotonhora inovhara uye isina kukwana kuzadza. Sei? Chigadzirwa chakagadzirwa chine makona akapinza, masikweya emukati izvo zvaisaita kuti simbi yakanyunguduka izare nekumhanya kukuru. Yakareruka prototype jecha kukanda, kunyangwe yakakasharara, ingadai yakakurumidza kuisa iyo geometry sedambudziko. Tingadai takaona kudiwa radii. Ndiwo rudzi rwechidzidzo chinodhura makumi ezviuru mukufa kwakagadziridzwa.
Apa ndipo apo mudiwa ane ruzivo rwakadzama foundry asingagone kutaurirana. Iwe unoda mumwe munhu anogona kutarisa muenzaniso weCAD uye pakarepo fungidzira mold, mutsara wekuparadzanisa, macores. Kambani yakadai Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nemakore avo makumi matatu ekukandira, inoshanda munzvimbo ino intuitively. Hazvisi zvekungogadzira mold; ndezvekupa mazano ekugadzirisa dhizaini ye mold kuita prototype-uye nekuwedzera, chikamu chekupedzisira-chinobudirira. Basa ravo kumativi ose shell mold casting, kukanda mari, uye akasiyana alloys zvinoreva kuti vanonzwisisa spectrum, saka vanonyatsoziva nguva uye nei yekukurudzira jecha kune prototype.
Maitiro: Inokurumidza, Yakasviba, uye Inodzidzisa
Saka, zvinonyatsoshanda sei kune imwe-kure kana pfupi pfupi? Kazhinji ibhuku rekushandisa kana semi-manual process. Iwe hausi kugadzira yakasimba, inogona kushandiswazve pateni yemuchina wekuumba. Zvingangodaro, iwe uri kugadzira yakanaka pateni kubva kune yepakati senge urethane board kana kunyange yakakwirira-density foam. Iyi pateni inozoshandiswa kugadzira mold yejecha, kazhinji ichishandisa jecha risina kubikwa kuitira kumhanya. Iyo mold inogona kunge iri nyore-zvikamu zviviri cope uye kudhonza, kana ingangoda zvidimbu zvisina kusununguka. Tarisiro iri pakubata iyo geometry, kwete pakuwana dhizaini-yepamusoro pekupedzisira.
Sarudzo yesimbi yakakosha. Iwe unoda kuenzanisa, zvakanyanya sezvinobvira, iyo alloy yakagadzirirwa kugadzirwa. Kana chikamu chekupedzisira chiri ductile iron, prototype yako inofanira kudirwa mu ductile iron. Izvi zvinoedza kuyerera kweiyo chaiyo alloy, iyo shrinkage rate, yayo yekudyisa zvinodiwa. Kudurura prototype mualuminium apo kugadzirwa kunenge kuri simbi kunenge kusingabatsiri kubva pakuita zvinhu. Iyi ndiyo imwe nharaunda uko hunyanzvi hwezvinhu zve foundry hwakakosha. Chiitiko cheQSY ne simbi yakakandwa, simbi, simbi isina tsvina, uye kunyange yakakosha nickel-based alloys zvinoreva kuti vanogona kukutungamira kune inomiririra zvinhu, kunyangwe kune prototype. Kupisa kwesimba rekudira superalloy inyika isina grey iron.
Mhedzisiro yakakosha sekudira. Iwe unozunza kunze, kugura masuwo nekusimuka, uye ipapo unonyatsoona zvaunazvo. Kutarisa kwekutanga kunogara kuchitaura. Unogona kuona mhango inooneka muchikamu chakakora, zvichiratidza kuti unoda musimu mukuru. Unogona kuona jecha richibvira pachikamu chitete, zvichiratidza kuti simbi yaipisa zvakanyanya kana kuti chikamu chacho chakanyanya kutetepa kuti chizadze zvakanaka. Iyi mbishi, mhinduro yekukurumidza. Iwe wobva waita kucheneswa kushoma-pamwe kukurumidza kupfura kuputika uye kupfuura pamusoro pemutsara wekuparadzanisa neguyo-zvakakwana kuti iite kushanda pakuyedza. Chinangwa ndechekuipinza mumushini kana kumuchina kuti uone kana ichishanda, uye zvakanyanya kukosha, kuti inotadza sei kana ikadaro.
Kana Chiri Chishandiso Chakakodzera (Uye Kana Chisiri)
Prototype jecha rekukanda rinopenya kune mamwe maapplication. Zvikamu zvakakura, kune imwe. Kazhinji ndiyo chete inodhura-inoshanda nzira ye prototype chikamu chiri mita kana kupfuura muhukuru. Heavy-chikamu zvikamu ndemumwe mumiriri akanaka, sezvo dzimwe nzira dzekukurumidza dzeprototyping dzichinetseka nesimbi yakasimba mavhoriyamu. Yakanakirawo zvikamu zvine makomba emukati akaomarara anoda jecha cores. Iwe unogona prototype iyo yepakati-yekugadzira maitiro pachayo. Uye zvechokwadi, zvakakosha kana zvimiro zveiyo chaiyo yekukanda alloy yakakosha pabvunzo, senge kupikisa kupisa kwe cobalt-based alloy kana kushorwa kwegiredhi chaiyo isina tsvina.
Asi haisi panacea. Kune zvidiki-diki, zvakatsanangurwa zvikamu zvine kushivirira kwakasimba, kukanda mari inogona kunge iri nani prototype nzira, kunyangwe yejecha-cast-cast chikamu chekugadzira, kungotarisa kukwana uye fomu. Kana iwe uchida gumi nemaviri akada kufanana prototypes ebvunzo batch, iyo hupfumi inogona kukusundidzira iwe kune ipfupi-inomhanya isingaperi mold kana kunyange machining. Uye kana kupedzisa kwepamusoro kana kurongeka kuri iko kunonyanya kunetseka pabvunzo, saka iwe unogona kunge uri nani pane machining. Kusimba kweiyo prototype jecha kukanda kuyedza kugadzirwa uye kuwanda kwekushanda kwedhizaini yakagadzirirwa kukanda jecha.
Muenzaniso unoshanda: takamboshanda pane prototype yedhizaini nyowani yakawanda. Geometry yakanga yakaoma, ine ndima dzinopindirana. Iyo nzira yekugadzira yaive yekuumba shell. Isu takashandisa prototype jecha kukanda (inonyatso nzira yegirinhi jecha) kuyedza dhizaini yekutanga. Iyo prototype yakaratidza nyaya huru yemhirizhonga mune imwe ndima iyo ingadai yakakonzera kuumbwa kwemarara. Isu takagadziridza iyo mumhanyi system zvichibva pane imwechete prototype kudururira. Patakazoenda paya chaipo shell mold casting process for pre-kugadzirwa, dambudziko iroro rakanga ratogadziriswa. Iyo prototype haina kutaridzika zvakanaka, asi yakachengetedza purojekiti.
Zvipingamupinyi Zvinooneka uye Sarudzo Chaiyo
Hazvisi zvese zvakanangana. Imwe yemarwadzo makuru emusoro ndeyekugadzira maitiro. Kune yechokwadi imwe-off, kuparadza chimiro chakagadzirwa mu mold chinogamuchirwa. Asi kana iwe uchifunga kuti ungangoda maviri kana matatu anodururwa kuti aite, iwe unoda yakasimba pateni. Izvo zvinosimudzira mutengo wekutanga uye nguva. Pane kugara uchitengeserana: yakawanda sei yatinodyara muiyo prototype tooling (iyo pateni) maringe nekungowana simbi muruoko?
Imwe pfungwa yakavanzika ijecha pacharo. Mafekitori ekugadzira anoshandisa rakadzorwa zvakasimba, jecha rakadzokororwa rine zvimwe zvinowedzera. Chitoro chemuenzaniso chinogona kushandisa rakasiyana, rinoshanda zvakasiyana-siyana jecha system. Thermal properties inosiyana.
